Oral complications of radiation therapy for head and neck cancer (HNC) are associated with a significant decline in oral health-related quality of life (OHQOL). The dentist, working with the radiation oncologist and the rest of the health care team, plays an important role in the prevention and management of these complications, but patients do not always receive care consistent with current guidelines. This study investigated barriers to recommended care. There is variability in knowledge and practice among dentists and radiation oncologists regarding the dental management of patients treated with head and neck radiotherapy (HNRT), and inadequate communication and collaboration between members of the patient's health care team contribute to inconsistencies in application of clinical care guidelines. There is on interest and need for continuing dental (CDE) and medical education (CME) on this topic. A questionnaire was developed to assess dentists' knowledge and practice of dental management of HNC patients and their interest in CDE on this topic. All members of the Michigan Dental Association (MDA) with email addresses were asked to complete the survey online, and a random sample of MDA members without email addresses was invited to complete a paper version of the same survey. All Michigan members of the American Society for Radiation Oncology (ASTRO) were invited to complete an online version of the survey modified for radiation oncologists. The response rate for dentists was 47.9% and radiation oncologists was 22.3%. Of the dentists who responded, 81% reported that a major barrier to providing dental treatment before radiotherapy was a lack of time between initial dental consultation and the start of radiation; inadequate communication between health care providers was blamed most frequently for this. Ten percent of the dentists and 25% of the radiation oncologists reported that they did not treat HNC patients because they lacked adequate training, and 55% of dental respondents said that they did not feel adequately trained in dental school to treat patients who have had head and neck radiation therapy. Most respondents (radiation oncologists 67%; dentists 72%) were interested in CDE and CME on this topic. These results suggest a need for CDE and CME for Michigan dentists and radiation oncologists on the oral management of HNC patients. Improved training and communication between health professionals could improve patient outcomes and more consistent application of clinical care guidelines.

Purpose: To perform a national survey of radiation oncologists and urologists about the type of resources used and the level of evidence needed to change clinical practice in localized prostate cancer. Methods and Materials: From a random sample, 1422 physicians were mailed a survey assessing the types of information used and what level of evidence could alter their clinical practice in prostate cancer. Multivariable logistic regression models were used to identify differences in physician characteristics for each outcome. Results: Survey response rates were similar for radiation oncologists and urologists (44% vs 46%; P=.46). Specialty-specific journals represented the most commonly usedmore » resource for informing the clinical practice for radiation oncologists (65%) and urologists (70%). Relative to radiation oncologists, urologists were less likely to report utilizing top-tier medical journals (25% vs 39%; adjusted odds ratio [OR] 0.50; P=.01) or cancer journals (22% vs 51%; adjusted OR 0.50; P<.001) but more likely to rely on clinical guidelines (46% vs 38%; adjusted OR 1.6; P=.006). Both radiation oncologists and urologists most commonly reported large randomized, clinical trials as the level of evidence to change treatment recommendations for localized prostate cancer (85% vs 77%; P=.009). Conclusions: Both specialties rely on their own specialty-specific journals and view randomized, clinical trials as the level of evidence needed to change clinical practice. Our study provides a context on meaningful ways of disseminating evidence for localized prostate cancer.« less

To examine characteristics of medical malpractice claims involving radiation oncologists closed during a 10-year period. Malpractice claims filed against radiation oncologists from 2003 to 2012 collected by a nationwide liability insurance trade association were analyzed. Outcomes included the nature of claims and indemnity payments, including associated presenting diagnoses, procedures, alleged medical errors, and injury severity. We compared the likelihood of a claim resulting in payment in relation to injury severity categories (death as referent) using binomial logistic regression. There were 362 closed claims involving radiation oncology, 102 (28%) of which were paid, resulting in $38 million in indemnity payments. The most common alleged errors included "improper performance" (38% of closed claims, 18% were paid; 29% [$11 million] of total indemnity), "errors in diagnosis" (25% of closed claims, 46% were paid; 44% [$17 million] of total indemnity), and "no medical misadventure" (14% of closed claims, 8% were paid; less than 1% [$148,000] of total indemnity). Another physician was named in 32% of claims, and consent issues/breach of contract were cited in 18%. Claims for injury resulting in death represented 39% of closed claims and 25% of total indemnity. "Improper performance" was the primary alleged error associated with injury resulting in death. Compared with claims involving death, major temporary injury (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.29-5.85, P=.009), significant permanent injury (OR 3.1, 95% CI 1.48-6.46, P=.003), and major permanent injury (OR 5.5, 95% CI 1.89-16.15, P=.002) had a higher likelihood of a claim resulting in indemnity payment. Improper performance was the most common alleged malpractice error. Claims involving significant or major injury were more likely to be paid than those involving death. Insights into the nature of liability claims against radiation oncologists may help direct efforts to improve quality of care and minimize the risk of being sued. Copyright © 2017 Elsevier Inc.

Purpose: To analyze error disclosure attitudes of radiation oncologists and to correlate error disclosure beliefs with survey-assessed disclosure behavior. Methods and Materials: With institutional review board exemption, an anonymous online survey was devised. An email invitation was sent to radiation oncologists (American Society for Radiation Oncology [ASTRO] gold medal winners, program directors and chair persons of academic institutions, and former ASTRO lecturers) and residents. A disclosure score was calculated based on the number or full, partial, or no disclosure responses chosen to the vignette-based questions, and correlation was attempted with attitudes toward error disclosure. Results: The survey received 176 responses:more » 94.8% of respondents considered themselves more likely to disclose in the setting of a serious medical error; 72.7% of respondents did not feel it mattered who was responsible for the error in deciding to disclose, and 3.9% felt more likely to disclose if someone else was responsible; 38.0% of respondents felt that disclosure increased the likelihood of a lawsuit, and 32.4% felt disclosure decreased the likelihood of lawsuit; 71.6% of respondents felt near misses should not be disclosed; 51.7% thought that minor errors should not be disclosed; 64.7% viewed disclosure as an opportunity for forgiveness from the patient; and 44.6% considered the patient's level of confidence in them to be a factor in disclosure. For a scenario that could be considerable, a non-harmful error, 78.9% of respondents would not contact the family. Respondents with high disclosure scores were more likely to feel that disclosure was an opportunity for forgiveness (P=.003) and to have never seen major medical errors (P=.004). Conclusions: The surveyed radiation oncologists chose to respond with full disclosure at a high rate, although ideal disclosure practices were not uniformly adhered to beyond the initial decision to disclose the occurrence of the error.« less

Abstract Introduction This paper reports the key findings of the Faculty of Radiation Oncology 2014 workforce census and compares the results with earlier surveys. Methods The census was conducted in mid‐2014 with distribution to all radiation oncologists, educational affiliates and trainees listed on the college database. There were six email reminders and responses were anonymous. The overall response rate was 76.1%. Results The age range of fellows was 32–96 (mean = 49 years, median = 47 years). The majority of the radiation oncologists were male (n = 263, 63%). The minority of radiation oncologists were of Asian descent (n = 43, 13.4%). Radiation oncologists graduated from medical school on average 23 years ago (median = 22 years). A minority of fellows (n = 66, 20%) held another postgraduate qualification. Most radiation oncologists worked, on average, at two practices (median = 2, range 1–7). Practising radiation oncologists worked predominantly in the public sector (n = 131, 49%), but many worked in both the public and private sectors (n = 94, 37%), and a minority worked in the private sector only (n = 38, 14%). The largest proportion of the workforce was from New South Wales accounting for 29% of radiation oncologists. Radiation oncologists worked an average of 43 h/week (median = 43 h, range 6–80). Radiation oncologists who worked in the private sector worked less hours than their public sector or public/private sector colleagues. (38.3 vs. 42.9 vs. 44.3 h, P = 0.042). Victorians worked the fewest average hours per week at 38 h and West Australians the most at 46 h/week. Radiation oncologists averaged 48 min for each new case, 17 min per follow up and 11 min for a treatment review. Radiation oncologists averaged 246 new patients per year (median = 250, range = 20–600) with men (average = 268), Western Australians (average = 354) and those in private practice seeing more (average = 275). Most radiation oncologists considered themselves as specialists (n = 151, 60%), but nearly all those from South Australia were generalists (n = 15, 94%) as were three‐quarters of those from private practice. A minority of radiation oncologist respondents (10%) intended to retire within 5 years with a further 16% within 10 years.There was a stabilisation of trainee numbers in Australia and New Zealand with no increase compared with 2010 (142 in 2014 vs. 143 in 2010). The most common age bracket for trainees remained 31–35 years. One‐third of trainees were of Asian descent and nearly half held other degrees. The majority of trainees were satisfied with their career, but 30% were not entirely satisfied. Nearly half of trainee respondents would have reconsidered their choice of specialty had they known about the possible oversupply in the workforce with 12.4% undecided about continuing their career in radiation oncology. There were still 16% of trainees with no protected time during the working week, and a further 21% with only 1 h. Only one trainee respondent preferred to work in private practice, and job availability remained a concern for 89% of respondents. Conclusions The radiation oncologist workforce numbers have increased at a much slower rate, and unemployment remained low. Many parameters remained similar to the 2010 survey. However, there has been a decrease in the average number of new patients seen per year, working hours and also a slight decrease in the time spent per new patient. The trainee numbers have stabilised, but job availability remained a concern. A significant proportion of trainees were not satisfied with their career. PMID:26511456

The American Society for Radiation Oncology (ASTRO) and American Urological Association (AUA) developed post-prostatectomy radiotherapy (RT) guidelines to aid patient counseling on adjuvant (ART) and salvage radiotherapy (SRT). Our study compared how aware and compliant Canadian radiation oncologists and urologists are to these guidelines. Our online survey was distributed through the Canadian Association of Radiation Oncology (CARO) and Canadian Urology Association (CUA) to radiation oncologists and urologists that treat prostate cancer. We used Wilcoxon rank-sum test and Chi-square test to compare radiation oncologists and urologists. P values for significant findings are reported. A total of 128 participants responded the survey, 52 radiation oncologists, and 76 urologists. The majority (82%) of radiation oncologists had read these guidelines, compared to only 49% of urologists (p < 0.001). Radiation oncologists were more likely to recommend ART >50% for adverse pathological findings post-radical prostatectomy compared to urologists (76 vs. 51%, p = 0.011). Urologists were more likely to monitor their patient's PSA level post-prostatectomy compared to radiation oncologists (93 vs. 77%, p = 0.016). Post-thematic analysis of open-ended questions revealed that urologists rarely refer patients to radiation oncologists for ART, with radiation oncologists confirming that they rarely receive referrals. This study demonstrates the low compliance to ASTRO/AUA guidelines. While radiation oncologists were more aware and compliant to guidelines, urologists were significantly more likely to monitor their patient's PSA. This study highlighted the need for better communication between urologists and radiation oncologists, especially in referrals for ART, to facilitate treatment delivery that is concordant with ASTRO/AUA guidelines.

Respiratory motion management (RMM) systems in external and stereotactic radiotherapies have been developed in the past two decades. Japanese medical service fee regulations introduced reimbursement for RMM from April 2012. Based on thorough discussions among the four academic societies concerned, these Guidelines have been developed to enable staff (radiation oncologists, radiological technologists, medical physicists, radiotherapy quality managers, radiation oncology nurses, and others) to apply RMM to radiation therapy for tumors subject to respiratory motion, safely and appropriately.

Purpose: To assess whether radiation oncologists and surgeons differ in their attitudes regarding the local management of breast cancer, and to examine coordination of care between these specialists. Methods and Materials: We surveyed attending surgeons and radiation oncologists who treated a population-based sample of patients diagnosed with breast cancer in metropolitan Detroit and Los Angeles. We identified 419 surgeons, of whom 318 (76%) responded, and 160 radiation oncologists, of whom 117 (73%) responded. We assessed demographic, professional, and practice characteristics; challenges to coordinated care; and attitudes toward management in three scenarios. Results: 92.1% of surgeons and 94.8% of radiation oncologistsmore » indicated access to a multidisciplinary tumor board. Nevertheless, the most commonly identified challenge to radiation oncologists, cited by 27.9%, was failure of other providers to include them in the treatment decision process early enough. Nearly half the surgeons (49.7%) stated that few or almost none of the breast cancer patients they saw in the past 12 months had consulted with a radiation oncologist before undergoing definitive surgery. Surgeons and radiation oncologists differed in their recommendations in management scenarios. Radiation oncologists were more likely to favor radiation than were surgeons for a patient with 3/20 lymph nodes undergoing mastectomy (p = 0.03); surgeons were more likely to favor more widely clear margins after breast conservation than were radiation oncologists (p = 0.001). Conclusions: Despite the widespread availability of tumor boards, a substantial minority of radiation oncologists indicated other providers failed to include them in the breast cancer treatment decision-making process early enough. Earlier inclusion of radiation oncologists may influence patient decisions, and interventions to facilitate this should be considered.« less

Cancer is the second leading cause of death in the USA, but there is minimal data on how oncology is taught to medical students. The purpose of this study is to characterize oncology education at US medical schools. An electronic survey was sent between December 2014 and February 2015 to a convenience sample of medical students who either attended the American Society for Radiation Oncology annual meeting or serve as delegates to the American Association of Medical Colleges. Information on various aspects of oncology instruction at participants’ medical schools was collected. Seventy-six responses from students in 28 states were received. Among the six most common causes of death in the USA, cancer reportedly received the fourth most curricular time. During the first, second, and third years of medical school, participants most commonly reported 6–10, 16–20, and 6–10 h of oncology teaching, respectively. Participants were less confident in their understanding of cancer treatment than workup/ diagnosis or basic science/natural history of cancer (p<0.01). During the preclinical years, pathologists, scientists/Ph.D.’s, and medical oncologists reportedly performed the majority of teaching, whereas during the clinical clerkships, medical and surgical oncologists reportedly performed the majority of teaching. Radiation oncologists were significantly less involved during both periods (p<0.01). Most schools did not require any oncology-oriented clerkship. During each mandatory rotation, ≤20 % of patients had a primary diagnosis of cancer. Oncology education is often underemphasized and fragmented with wide variability in content and structure between medical schools, suggesting a need for reform. PMID:26123764

Number of Radiation Oncologists in Korea, Adequate or Surplus?

PubMed Central

2006-01-01

Purpose The purpose of this research is to discern and address the issues related to the radiation oncology manpower supply and its distribution. Materials and Methods The statistical data of the Annual Report of the Korea Central Cancer Registry (KCCR) from 1997 to 2002 and the Annual Report of the Korean Society of Radiation Oncology (KOSTRO) from 1997 to 2004 were used to predict the status of the human resources in 2015. The estimated demand and supply were calculated with the Microsoft Excel® program (Microsoft, Redmond, WA). Results The demand for radiation oncologists is estimated to be 161 in 2015 and about 4.9 radiation oncologists will be in demand annually. In contrast, an average of 15 new radiation oncologists will be supplied annually so that the accumulated surplus of radiation oncologists until 2015 is estimated to be 74.1. The main reason for the surplus comes from the discrepancy between the increased number of radiation therapy patients and the need for radiation oncologists. When there is an increase of 1,000 radiation therapy patients, the demand for radiation oncologists increases only by 2.4. This phenomenon is especially evident in the top 10 hospitals where the average number of radiation therapy patients per radiation oncologist is 341, which is 58% higher than the average number (215) of other 46 hospitals. Conclusion To prevent a surplus and to maintain the quality of management, the number of radiation therapy patients per radiation oncologist should be limited. Furthermore, coordinate control of the number of residency positions should be seriously considered. PMID:19771261

Radiation therapy for pediatric patients often includes the use of intravenous anesthesia with supplemental oxygen delivered via the nasal cannula. Here, we describe the use of an adaptive anesthesia technique for electron irradiation of the right naris in a preschool-aged patient treated under anesthesia. The need for an intranasal bolus plug precluded the use of standard oxygen supplementation. This novel technique required the multidisciplinary expertise of anesthesiologists, radiation therapists, medical dosimetrists, medical physicists, and radiation oncologists to ensure a safe and reproducible treatment course.

We constructed a remote radiation planning support system between Kyushu University Hospital (KUH) in Fukuoka and Kyushu University Beppu Hospital (KBH) in Oita. Between two institutions, radiology information system for radiotherapy division (RT-RIS) and radiation planning system (RTPS) were connected by virtual private network (VPN). This system enables the radiation oncologists at KUH to perform radiotherapy planning for the patients at KBH. The detail of the remote radiation planning support system in our institutions is as follows: The radiation oncologist at KBH performs radiotherapy planning and the data of the patients are sent anonymously to the radiation oncologists at KUH. The radiation oncologists at KUH receive the patient's data, access to RTPS at KBH, verify or change the radiation planning at KBH: Radiation therapy is performed at KBH according to the confirmed plan by the radiation oncologists at KUH. Our remote radiation planning system is useful for providing radiation therapy with safety and accuracy.

The aim of this prospective study was to evaluate daily set-up by a radiation oncologist and by radiation therapists using on-board imaging of patients with head and neck cancer in order to calculate margin to PTV (planning target volume) and intent partial delegation of positioning images control. The files of 11 patients with head and neck cancer treated on a Synergy™ (Elekta™) accelerator with on-board imaging system were evaluated. Daily kV-kV images were double-blind reviewed by radiation therapists (7 participants) and by one radiation oncologist. The radiation oncologist's measures were used for margin calculation from CTV to PTV. The difference of measures and the concordance of decisions between radiation therapists and the radiation oncologist were calculated. The 325 measures made by the radiation oncologist resulted in a margin of 5mm to be applied to the CTV in each direction. Nine hundred seventy-seven measures were made by the radiation oncologist and radiation therapists with a difference of 3mm or less in 98.46%. The concordance of decision for a 4mm difference or less to the isocenter was 96.7%. This study confirms the 5mm PTV margin mostly used in ORL. The small gap between the radiation oncologist's and therapists' measures allows a partial delegation of positioning images control.

Purpose: To assess whether an education program on CT and MRI prostate anatomy would reduce inter- and intraobserver prostate contouring variation among experienced radiation oncologists. Methods and Materials: Three patient CT and MRI datasets were selected. Five radiation oncologists contoured the prostate for each patient on CT first, then MRI, and again between 2 and 4 weeks later. Three education sessions were then conducted. The same contouring process was then repeated with the same datasets and oncologists. The observer variation was assessed according to changes in the ratio of the encompassing volume to intersecting volume (volume ratio [VR]), across setsmore » of target volumes. Results: For interobserver variation, there was a 15% reduction in mean VR with CT, from 2.74 to 2.33, and a 40% reduction in mean VR with MRI, from 2.38 to 1.41 after education. A similar trend was found for intraobserver variation, with a mean VR reduction for CT and MRI of 9% (from 1.51 to 1.38) and 16% (from 1.37 to 1.15), respectively. Conclusion: A well-structured education program has reduced both inter- and intraobserver prostate contouring variations. The impact was greater on MRI than on CT. With the ongoing incorporation of new technologies into routine practice, education programs for target contouring should be incorporated as part of the continuing medical education of radiation oncologists.« less

Purpose: To determine the characteristics, needs, and concerns of the current radiation oncology workforce, evaluate best practices and opportunities for improving quality and safety, and assess what we can predict about the future workforce. Methods and Materials: An online survey was distributed to 35,204 respondents from all segments of the radiation oncology workforce, including radiation oncologists, residents, medical dosimetrists, radiation therapists, medical physicists, nurse practitioners, nurses, physician assistants, and practice managers/administrators. The survey was disseminated by the American Society for Radiation Oncology (ASTRO) together with specialty societies representing other workforce segments. An overview of the methods and global results ismore » presented in this paper. Results: A total of 6765 completed surveys were received, a response rate of 19%, and the final analysis included 5257 respondents. Three-quarters of the radiation oncologists, residents, and physicists who responded were male, in contrast to the other segments in which two-thirds or more were female. The majority of respondents (58%) indicated they were hospital-based, whereas 40% practiced in a free-standing/satellite clinic and 2% in another setting. Among the practices represented in the survey, 21.5% were academic, 25.2% were hospital, and 53.3% were private. A perceived oversupply of professionals relative to demand was reported by the physicist, dosimetrist, and radiation therapist segments. An undersupply was perceived by physician's assistants, nurse practitioners, and nurses. The supply of radiation oncologists and residents was considered balanced. Conclusions: This survey was unique as it attempted to comprehensively assess the radiation oncology workforce by directly surveying each segment. The results suggest there is potential to improve the diversity of the workforce and optimize the supply of the workforce segments. The survey also provides a benchmark for future studies, as many changes in the healthcare field exert pressure on the workforce.« less

An online survey was distributed to 35,204 respondents from all segments of the radiation oncology workforce, including radiation oncologists, residents, medical dosimetrists, radiation therapists, medical physicists, nurse practitioners, nurses, physician assistants, and practice managers/administrators. The survey was disseminated by the American Society for Radiation Oncology (ASTRO) together with specialty societies representing other workforce segments. An overview of the methods and global results is presented in this paper. A total of 6765 completed surveys were received, a response rate of 19%, and the final analysis included 5257 respondents. Three-quarters of the radiation oncologists, residents, and physicists who responded were male, in contrast to the other segments in which two-thirds or more were female. The majority of respondents (58%) indicated they were hospital-based, whereas 40% practiced in a free-standing/satellite clinic and 2% in another setting. Among the practices represented in the survey, 21.5% were academic, 25.2% were hospital, and 53.3% were private. A perceived oversupply of professionals relative to demand was reported by the physicist, dosimetrist, and radiation therapist segments. An undersupply was perceived by physician's assistants, nurse practitioners, and nurses. The supply of radiation oncologists and residents was considered balanced. This survey was unique as it attempted to comprehensively assess the radiation oncology workforce by directly surveying each segment. The results suggest there is potential to improve the diversity of the workforce and optimize the supply of the workforce segments. The survey also provides a benchmark for future studies, as many changes in the healthcare field exert pressure on the workforce. Copyright © 2013 The Authors. Published by Elsevier Inc.

The present survey investigates the views of medical oncologists, general practitioners (GPs) and patients about the various surveillance strategies. An online survey was conducted in Italy on a population of 329 medical oncologists, 380 GPs and 350 patients. Most of GPs (n = 291; 76%) claim that follow-up should be provided by the collaboration between GPs and medical oncologists. Most medical oncologists report to have a poor relationship with GPs (n = 151; 46%) or no relationships at all (n = 14; 4%). Most patients believe there is no real collaboration between medical oncologists and GPs (n = 138; 54%). GPs, medical oncologists and patients share the idea that the collaboration between oncologists and GPs for surveillance of cancer survivors is poor and should be improved.

The current guidelines do not delineate the types of providers that should participate in early breast cancer follow-up care (within 3 years after completion of treatment). This study aimed to describe the types of providers participating in early follow-up care of older breast cancer survivors and to identify factors associated with receipt of follow-up care from different types of providers. Stages 1-3 breast cancer survivors treated from 2000 to 2007 were identified in the Surveillance, Epidemiology and End results Medicare database (n = 44,306). Oncologist (including medical, radiation, and surgical) follow-up and primary care visits were defined using Medicare specialty provider codes and linked American Medical Association (AMA) Masterfile. The types of providers involved in follow-up care were summarized. Stepped regression models identified factors associated with receipt of medical oncology follow-up care and factors associated with receipt of medical oncology care alone versus combination oncology follow-up care. Oncology follow-up care was provided for 80 % of the patients: 80 % with a medical oncologist, 46 % with a surgeon, and 39 % with a radiation oncologist after radiation treatment. The patients with larger tumor size, positive axillary nodes, estrogen receptor (ER)-positive status, and chemotherapy treatment were more likely to have medical oncology follow-up care than older patients with higher Charlson comorbidity scores who were not receiving axillary care. The only factor associated with increased likelihood of follow-up care with a combination of oncology providers was regular primary care visits (>2 visits/year). Substantial variation exists in the types of providers that participate in breast cancer follow-up care. Improved guidance for the types of providers involved and delineation of providers' responsibilities during follow-up care could lead to improved efficiency and quality of care.

Purpose: To review the dose limits and standardize the three-dimenional (3D) radiographic definition for the organs at risk (OARs) for thoracic radiotherapy (RT), including the lung, proximal bronchial tree, esophagus, spinal cord, ribs, and brachial plexus. Methods and Materials: The present study was performed by representatives from the Radiation Therapy Oncology Group, European Organization for Research and Treatment of Cancer, and Soutwestern Oncology Group lung cancer committees. The dosimetric constraints of major multicenter trials of 3D-conformal RT and stereotactic body RT were reviewed and the challenges of 3D delineation of these OARs described. Using knowledge of the human anatomy andmore » 3D radiographic correlation, draft atlases were generated by a radiation oncologist, medical physicist, dosimetrist, and radiologist from the United States and reviewed by a radiation oncologist and medical physicist from Europe. The atlases were then critically reviewed, discussed, and edited by another 10 radiation oncologists. Results: Three-dimensional descriptions of the lung, proximal bronchial tree, esophagus, spinal cord, ribs, and brachial plexus are presented. Two computed tomography atlases were developed: one for the middle and lower thoracic OARs (except for the heart) and one focusing on the brachial plexus for a patient positioned supine with their arms up for thoracic RT. The dosimetric limits of the key OARs are discussed. Conclusions: We believe these atlases will allow us to define OARs with less variation and generate dosimetric data in a more consistent manner. This could help us study the effect of radiation on these OARs and guide high-quality clinical trials and individualized practice in 3D-conformal RT and stereotactic body RT.« less

Vu, Charles C.; Lanni, Thomas B.; Robertson, John M., E-mail: JRobertson@beaumont.edu

Purpose: The purposes of this study were to summarize recently published data on Medicare reimbursement to individual radiation oncologists and to identify the causes of variation in Medicare reimbursement in radiation oncology. Methods and Materials: The Medicare Provider Utilization and Payment Data: Physician and Other Supplier Public Use File (POSPUF), which details nearly all services provided by radiation oncologists in 2012, was used for this study. The data were filtered and analyzed by physician and by billing code. Statistical analysis was performed to identify differences in reimbursements based on sex, rurality, billing of technical services, or location in a certificatemore » of need (CON) state. Results: There were 4135 radiation oncologists who received a total of $1,499,625,803 in payments from Medicare in 2012. Seventy-five percent of radiation oncologists were male. The median reimbursement was $146,453. The code with the highest total reimbursement was 77418 (radiation treatment delivery intensity modulated radiation therapy [IMRT]). The most commonly billed evaluation and management (E/M) code for new visits was 99205 (49%). The most commonly billed E/M code for established visits was 99213 (54%). Forty percent of providers billed none of their new office visits using 99205 (the highest E/M billing code), whereas 34% of providers billed all of their new office visits using 99205. For the 1510 radiation oncologists (37%) who billed technical services, median Medicare reimbursement was $606,008, compared with $93,921 for all other radiation oncologists (P<.001). On multivariate analysis, technical services billing (P<.001), male sex (P<.001), and rural location (P=.007) were predictive of higher Medicare reimbursement. Conclusions: The billing of technical services, with their high capital and labor overhead requirements, limits any comparison in reimbursement between individual radiation oncologists or between radiation oncologists and other specialists. Male sex and rural practice location are independent predictors of higher total Medicare reimbursements.« less

Objectives Studies reporting healthcare resourse use (HRU) for melanoma, one of the most costly cancers to treat, are limited. Using consistent, robust methodology, this study estimated HRU associated with the treatment of metastatic melanoma in eight countries. Methods Using published literature and clinician input, treatment phases were identified: active systemic treatment (pre-progression); disease progression; best supportive care (BSC)/palliative care; and terminal care. HRU elements were identified for each phase and estimates of the magnitude and frequency of use in clinical practice were obtained through country-specific Delphi panels, comprising healthcare professionals with experience in oncology (n = 8). Results Medical oncologists are the key care providers for patients with metastatic melanoma, although in Germany dermato-oncologists also lead care. During the active systemic treatment phase, each patient was estimated to require 0.83-2 consultations with a medical oncologist/month across countries; the median number of such assessments in 3 months was highest in Canada (range = 3.5-5) and lowest in France, the Netherlands and Spain (1). Resource use during the disease progression phase was intensive and similar across countries: all patients were estimated to consult with medical oncologists and 10-40% with a radiation oncologist; up to 40% were estimated to require a brain MRI scan. During the BSC/palliative care phase, all patients were estimated to consult with medical oncologists, and most to consult with a primary care physician (40-100%). Limitations Panelists were from centers of excellence, thus results may not reflect care within smaller hospitals; data obtained from experts may be less variable than data from broader clinical practice. Treatments for metastatic melanoma are continually emerging, thus some elements of our work could be superseded. Conclusions HRU estimates were substantial and varied across countries for some resources. These data could be used with country-specific costs to elucidate costs for the management of metastatic melanoma.

Purpose This study was designed to evaluate the communication gap between Korean medical oncologists and cancer patients on complementary and alternative medicine (CAM). Materials and Methods Cross sectional studies utilized the responses of 59 medical oncologists and 211 patients. To understand the communication gap, perceived reasons and nondisclosure of CAM use, reactions of physicians to disclosure, and expectations for CAM were analyzed. Data were compared with use of the chi-squared test. Results Both medical oncologists and patients were in accord that CAM use would privde the patients with a feeling of hope. The medical oncologists believed more often than patients to attribute CAM use for control over medical care decisions, for the treatment of an incurable disease or as a nontoxic approach (p<0.05). Regarding reasons for nondisclosure, medical oncologists were more likely to think that physicians would not understand the use of CAM, discontinue treatment or disapprove of the use of CAM (p<0.0001). Patients attributed nondisclosure mainly to the lack of questioning about CAM. Medical oncologists were more likely to warn of the risks with CAM use and less likely to encourage the use of CAM than perceived by patients (p=0.01). Patients expected that CAM could cure disease, extend survival, relieve symptoms and improve the immune system or quality of life more often than medical oncologists (p<0.05). Conclusion Given the discrepant views of medical oncologists and patients on the use of CAM, medical oncologists should be aware of the discrepancies and attempt to resolve any differences.

Despite multiple randomized trials showing the efficacy of hypofractionated radiation therapy in early-stage breast cancer, the United States has been slow to adopt this treatment. The goal of this study was to evaluate the impact of individual radiation oncologists on the early adoption of hypofractionated radiation therapy for early-stage breast cancer. We identified 22,233 Medicare beneficiaries with localized breast cancer that was diagnosed from 2004 to 2011 who underwent breast-conserving surgery with adjuvant radiation. Multilevel, multivariable logistic models clustered by radiation oncologist and geographic practice area were used to determine the impact of the provider and geographic region on the likelihood of receiving hypofractionated compared with standard fractionated radiation therapy while controlling for a patient's clinical and demographic covariates. Odds ratios (OR) describe the impact of demographic or clinical covariates, and the median OR (MOR) describes the relative impact of the individual radiation oncologist and geographic region on the likelihood of undergoing hypofractionated radiation therapy. Among the entire cohort, 2333 women (10.4%) were treated with hypofractionated radiation therapy, with unadjusted rates ranging from 0.0% in the bottom quintile of radiation oncologists to 30.4% in the top quintile. Multivariable analysis found that the individual radiation oncologist (MOR 3.08) had a greater impact on the use of hypofractionation than did geographic region (MOR 2.10) or clinical and demographic variables. The impact of the provider increased from the year 2004 to 2005 (MOR 2.82) to the year 2010 to 2011 (MOR 3.16) despite the publication of long-term randomized trial results in early 2010. Male physician and radiation oncologists treating the highest volume of breast cancer patients were less likely to perform hypofractionation (P<.05). The individual radiation oncologist strongly influenced the likelihood of a patient's receiving hypofractionated radiation therapy, and this trend increased despite the publication of long-term data showing equivalence to standard fractionation. Future research should focus on physician-related factors that influence this decision. Copyright © 2016 Elsevier Inc. All rights reserved.

Proton radiotherapy is a relatively scarce treatment modality in radiation oncology, with only nine centers currently operating in the United States. Funded by Public Law 107-248, the University of Pennsylvania and the Walter Reed Army Medical Center have developed a remote proton radiation therapy solution with the goals of improving access to proton radiation therapy for Department of Defense (DoD) beneficiaries while minimizing treatment delays and time spent away from home/work (time savings of up to 3 weeks per patient). To meet both Health Insurance Portability and Accountability Act guidelines and the more stringent security restrictions imposed by the DoD, our program developed a hybrid remote proton radiation therapy solution merging a CITRIX server with a JITIC-certified (Joint Interoperability Test Command) desktop videoconferencing unit. This conduit, thoroughly tested over a period of 6 months, integrates both institutions' radiation oncology treatment planning infrastructures into a single entity for DoD patients' treatment planning and delivery. This telemedicine solution enables DoD radiation oncologists and medical physicists the ability to (1) remotely access a proton therapy treatment planning platform, (2) transfer patient plans securely to the University of Pennsylvania patient database, and (3) initiate ad-hoc point-to-point and multipoint videoconferences to dynamically optimize and validate treatment plans. Our robust and secure remote treatment planning solution grants DoD patients not only access to a state-of-the-art treatment modality, but also participation in the treatment planning process by Walter Reed Army Medical Center radiation oncologists and medical physicists. This telemedicine system has the potential to lead to a greater integration of military treatment facilities and/or satellite clinics into regional proton therapy centers.

Breast radiotherapy treatment is commonly managed by a multidisciplinary team to ensure optimal delivery of care. We sought a new model of care whereby a clinical specialist radiation therapist (CSRT) delineates the cavity target for whole breast radiotherapy treatment planning and the radiation oncologist validates the contour during final plan review. This study evaluated the radiation oncologist's acceptance of these contours and identified characteristics of cavities suitable for CSRT-directed contouring. Following specialised breast oncology education and training by the radiation oncologist, the CSRT prospectively delineated cavities in 30 tangential breast radiotherapy cases and consulted the radiation oncologist in 'complex' cases but directed 'non-complex' cases for treatment planning. Changes to CSRT contours were evaluated using the conformity index. Breast density, time since surgery and cavity location, size and visualisation score [CVS: range 1 (no visible cavity) to 5 (homogenous cavity)] were captured. Of the 30 CSRT delineated cavities contours, the CSRT directed 20 (66.7%) cases for planning without radiation oncology review; 19 were accepted (without changes) by the radiation oncologist upon final plan review and one was changed by the radiation oncologist (conformity index = 0.93) for boost treatment and did not affect the tangential treatment plan. Ten (33.3%) cases, all CVS ≤ 3, were reviewed with the radiation oncologist before planning (conformity index = 0.88 ± 0.12). CVS was inversely correlated with breast density and cavity size (P < 0.01). The CSRT delineated cavities appropriate for clinical radiotherapy treatment planning in women with well-visualised cavities, whereas 'complex' cases with dense breast parenchyma, CVS ≤ 3, and/or cases needing boost radiotherapy treatment required review with the radiation oncologist before planning.

To summarize the basis for brachytherapy-associated legal complaints. The cases summarized here were those worked on by one author (KW) from 1992 through 2002. Summary information about cases is kept solely for the purpose of informing opposing counsel regarding past experience as a defendant or expert witness. No information summarized here is kept for medical research purposes. KW was the defendant in three cases, and an expert witness in the remaining 10 cases. Eleven cases were initiated due to a prostatic-rectal fistula--an abnormal communication between the prostatic urethra and rectum formed because of breakdown of irradiated tissue. Of the cases not involving a fistula, one was initiated due to chronic urinary burning, and the other arose from a patient identification mix-up, such that the plaintiff was treated with the implant planned for another patient. The principal physician defendant(s), after pre-trial winnowing, was the radiation oncologist alone in eight cases and the radiation oncologist and the urologist in five cases. In no case was a urologist named as a defendant without the radiation oncologist. None of the eleven rectal fistula cases involved an egregious seed placement error. Instead, plaintiff attorneys typically claimed breach of standard for care for what most physicians would likely consider to be variations within the standard of care. Prostate brachytherapists should brace themselves for the likelihood of more lawsuits. In addition to fistulas, plaintiff attorneys are likely to devise more bases for lawsuits in the future.

Fertility preservation (FP) aims to help individuals overcome the infertility associated with cancer treatments such as chemotherapy and radiation. The objective of this study was to assess the awareness, attitudes and knowledge of oncologists' and clinical practitioners' (CPs) about fertility preservation and its options in Lebanon. This was a cross-sectional study with surveys carried out between March 2012 and February 2013 on CPs at the American University of Beirut Medical Centre and Saint Jude's Children Cancer Centre as well as all registered oncologists in Lebanon. Ninety percent of CPs (n = 88) and 94% of oncologists (n = 53) agreed that fertility preservation should be discussed with patient before their cancer treatment. Our data showed a gender bias in relation to patients being informed of their FP options, as well as conflicting knowledge of FP options available in Lebanon among oncologists. The CPs were more likely to have accurate knowledge of FP options and treatment than oncologists. A proactive approach is required to: (1) increase the awareness and knowledge of FP; (2) improve attitudes towards FP; and (3) encourage its communication between CPs, oncologists and patients in Lebanon. Increased education programs, awareness campaigns and development of dedicated FP centres are needed.

(18)F-Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) has benefits in target volume (TV) definition in radiotherapy treatment planning (RTP) for non-small-cell lung cancer (NSCLC); however, an optimal protocol for TV delineation has not been determined. We investigate volumetric and positional variation in gross tumor volume (GTV) delineation using a planning PET/CT among three radiation oncologists and a PET radiologist. RTP PET/CT scans were performed on 28 NSCLC patients (Stage IA-IIIB) of which 14 patients received prior induction chemotherapy. Three radiation oncologists and one PET radiologist working with a fourth radiation oncologist independently delineated the GTV on CT alone (GTV(CT)) and on fused PET/CT images (GTV(PETCT)). The mean percentage volume change (PVC) between GTV(CT) and GTV(PETCT) for the radiation oncologists and the PVC between GTV(CT) and GTV(PETCT) for the PET radiologist were compared using the Wilcoxon signed-rank test. Concordance index (CI) was used to assess both positional and volume change between GTV(CT) and GTV(PETCT) in a single measurement. For all patients, a significant difference in PVC from GTV(CT) to GTV(PETCT) exists between the radiation oncologist (median, 5.9%), and the PET radiologist (median, -0.4%, p = 0.001). However, no significant difference in median concordance index (comparing GTV(CT) and GTV(FUSED) for individual cases) was observed (PET radiologist = 0.73; radiation oncologists = 0.66; p = 0.088). Percentage volume changes from GTV(CT) to GTV(PETCT) were lower for the PET radiologist than for the radiation oncologists, suggesting a lower impact of PET/CT in TV delineation for the PET radiologist than for the oncologists. Guidelines are needed to standardize the use of PET/CT for TV delineation in RTP. Copyright © 2010 Elsevier Inc. All rights reserved.

The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.

This study was conducted to explore the process and operation of a cancer multidisciplinary team (MDT) after the reimbursement decision in Korea, and to identify ways to overcome the major barriers to effective and sustainable MDTs. Approximately 1,000 cancer specialists, including medical oncologists, surgical oncologists, radiation oncologists, pathologists, and radiologists in general hospitals in Koreawere invited to complete the survey. The questionnaire covered the following topics: organizational structure of MDTs, candidates for consulting, the clinical decision-making initiative, and responsibility for dealing with legal disputes. We collected a total of 179 responses (18%) from physicians at institutions where an MDT approach was active. A surgical oncologist (91%), internist (90%),radiologist (89%),radiation oncologist (86%), pathologist (71%), and trainees (20%) regularly participated in MDT operations. Approximately 55% of respondents stated that MDTs met regularly. In cases of a split opinion, the physician in charge (69%) or chairperson (17%) made the final decision, and most (86%) stated they followed the final decision. About 15% and 32% of respondents were "very satisfied" and "satisfied," respectively, with the current MDT's operations. Among 38 institutional representatives, 34% responded that the MDT operation became more active and 18% stated an MDT was newly implemented after the reimbursement decision. The reimbursement decision invigorated MDT operations in almost half of eligible hospitals. Dissatisfaction regarding current MDTs was over 50%, and the high discordance rates regarding risk sharing suggest that it is necessary to revise the current system of MDTs.

This study details the distribution and trends of doses due to occupational radiation exposure among radiation workers from participating medical institutions in Kenya, where monthly dose measurements were collected for a period of one year ranging from January to December in 2007. A total of 367 medical radiation workers were monitored using thermoluminescent dosemeters. They included radiologists (27%), oncologists (2%), dentists (4%), Physicists (5%), technologists (45%), nurses (4%), film processor technicians (3%), auxiliary staff (4%), and radiology office staff (5%). The average annual effective dose of all categories of staff was found to range from 1.19 to 2.52 mSv. This study formed the initiation stage of wider, comprehensive and more frequent monitoring of occupational radiation exposures and long-term investigations into its accumulation patterns in our country.

Short-course radiotherapy (SC-RT) and long-course chemoradiotherapy (LC-CRT) are accepted neoadjuvant treatments of rectal cancer. In the current study, the authors surveyed US radiation oncologists to assess practice patterns and attitudes regarding SC-RT and LC-CRT for patients with rectal cancer. The authors distributed a survey to 1701 radiation oncologists regarding treatment of neoadjuvant rectal cancer. Respondents were asked questions regarding the number of patients with rectal cancer treated, preference for SC-RT versus LC-CRT, and factors influencing regimen choice. Of 1659 contactable physicians, 182 responses (11%) were received. Approximately 83% treated at least 5 patients with rectal cancer annually. The majority of responding radiation oncologists (96%) preferred neoadjuvant LC-CRT for the treatment of patients with locally advanced rectal cancer and 44% never used SC-RT. Among radiation oncologists using SC-RT, respondents indicated they would not recommend this regimen for patients with low (74%) or bulky tumors (70%) and/or concern for a positive circumferential surgical resection margin (69%). The most frequent reasons for not offering SC-RT were insufficient downstaging for sphincter preservation (53%) and a desire for longer follow-up (45%). Many radiation oncologists indicated they would prescribe SC-RT for patients not receiving chemotherapy (62%) or patients with a geographic barrier to receiving LC-CRT (82%). Patient comorbidities appeared to influence regimen preferences for 79% of respondents. Approximately 20% of respondents indicated that altered oncology care reimbursement using capitated payment by diagnosis would impact their consideration of SC-RT. US radiation oncologists rarely use neoadjuvant SC-RT despite 3 randomized controlled trials demonstrating no significant differences in outcome compared with LC-CRT. Further research is necessary to determine whether longer follow-up coupled with the benefits of lower cost, increased patient convenience, and lower acute toxicity will increase the adoption of SC-RT by radiation oncologists in the United States.

The purpose of the present study was to examine 1) characteristics and attitudes of oncologists toward exercise and toward recommending exercise to their patients, 2) association among oncologists' own physical activity levels, exercise recommendations, and their attitudes toward recommending exercise. A total of 167 oncologists participated in this survey study (41 surgeons, 78 medical oncologists, 25 radiation oncologists, and 21 others). Most oncologists included in the study treat more than one type of cancer, including colorectal, gastric, breast, lung, and liver cancer. To analyze the data, the one-way ANOVA, and t-test were used. All data were indicated for mean, SD, and proportions. Most oncologists agreed that exercise is beneficial (72.8%) and important (69.6%), but only 39.2% of them agreed that exercise is safe, and only 7.2% believed that cancer patients manage to exercise during cancer treatment. Forty-six percentage of the surveyed oncologists recommended exercise to their patients during the past month. The average amount of participation in physical activity by oncologists who participated in the study was 139.5 ± 120.3 min per week, and 11.4% of the study participants met the American College of Sports Medicine (ACSM) guidelines. Oncologists' own physical activity levels were associated with their attitudes toward recommending exercise. Belief in the benefits of exercise in the performance of daily tasks, improvement of mental health, and the attenuation of physical decline from treatment were the three most prevalent reasons why oncologists recommend exercise to their patients. Barriers to recommending exercise to patients included lack of time, unclear exercise recommendations, and the safety of patients. Oncologists have favorable attitudes toward exercise and toward recommending exercise to their patients during treatment. However, they also experience barriers to recommending exercise, including lack of time, unclear exercise guidelines for cancer patients, and concerns regarding the safety of exercise.

Purpose: To evaluate (1) the quantity and quality of current undergraduate oncology teaching at a major Canadian medical school; and (2) curricular changes over the past decade, to enhance local oncology education and provide insight for other educators. Methods and Materials: Relevant 2011-2012 undergraduate curricular sessions were extracted from the University of Toronto curriculum mapping database using keywords and database identifiers. Educational sessions were analyzed according to Medical Council of Canada objectives, discussion topics, instructor qualifications, teaching format, program year, and course subject. Course-related oncology research projects performed by students during 2000 to 2012 were extracted from another internal database.more » Elective choices of clerks during 2008-2014 were retrieved from the institution. The 2011-2012 and 2000-2001 curricula were compared using common criteria. Results: The 2011-2012 curriculum covers 5 major themes (public health, cancer biology, diagnosis, principles of care, and therapy), which highlight 286 oncology teaching topics within 80 sessions. Genitourinary (10, 12.5%), gynecologic (8, 10.0%), and gastrointestinal cancers (7.9, 9.8%) were the most commonly taught cancers. A minority of sessions were taught by surgical oncologists (6.5, 8.1%), medical oncologists (2.5, 3.1%), and radiation oncologists (1, 1.2%). During 2000-2012, 9.0% of students (233 of 2578) opted to complete an oncology research project. During 2008-2014, oncology electives constituted 2.2% of all clerkship elective choices (209 of 9596). Compared with pre-2001 curricula, the 2012 oncology curriculum shows notable expansion in the coverage of epidemiology (6:1 increase), prevention (4:1), screening (3:1), and molecular biology (6:1). Conclusions: The scope of the oncology curriculum has grown over the past decade. Nevertheless, further work is needed to improve medical student knowledge of cancers, particularly those relevant to public health needs. Defining minimum curricular content, emphasizing content based on population needs, and ensuring educational delivery with the support and expertise of oncologists and non-oncologists will be essential next steps.« less

Oral Cavity Cancer: Risk Factors, Pathology, and Management.

PubMed

Ernani, Vinicius; Saba, Nabil F

2015-01-01

Oral cavity cancers are predominantly squamous cell carcinomas, which arise from premalignant lesions through a multistep carcinogenesis process. Tobacco and alcohol are the major etiologic factors, although human papillomavirus has also recently been implicated as a causative agent. The possibility of a second primary malignancy should be considered during the diagnostic evaluation of head and neck cancers, as well as during the posttreatment surveillance phase. The goals of treatment are not only to improve survival outcomes but also to preserve organ function. These cancers are generally treated with a combination of surgery, radiation therapy, and chemotherapy. A multidisciplinary approach, involving surgeons, medical oncologists, and radiation oncologists, as well as dentists, dietitians, and rehabilitation therapists, is generally required for optimal treatment planning and management of patients with head and neck cancer. © 2015 S.

Family members (FMs) regularly attend oncology consultations. However, limited studies have assessed actual behaviours of oncologists, patients and FMs - particularly during decision-making. The current study aimed the following: (i) to rigorously develop a family (kin) interaction coding system (KINcode) capturing communication and decision-making behaviours of FMs and family-relevant behaviours of oncologists and patients and (ii) to apply KINcode to initial oncology consultations. The 80-item KINcode system was developed and applied to 72 transcripts of audiotaped medical/radiation oncology consultations including an FM, collected as part of two previous studies. The role of the FM varied considerably within the one encounter, with 33% of FMs assuming three or more roles across the four consultation stages. Whilst most FMs asked treatment decision questions (71%), a minority engaged in other behaviours such as prompting patient questions (4%) or providing information relevant to the decision to the oncologist (18%). Although oncologists rarely initiated interaction with FMs such as in rapport building (18%) or asking FMs questions (25%), they were typically fully responsive to FM questions (90%). Many patients asked their FM a question (42%), but few elicited the FM's decision preferences (4%). This study provides novel insights into the complex nature of family involvement. The findings highlight potentially positive FM-focused consultation behaviours such as oncologist responsiveness to family questions and potential areas for improvement such as rapport building, invitation of questions and validation of the family's role. Family-specific communication skills training should be considered in medical student and professional education settings. Copyright © 2015 John Wiley & Sons, Ltd.

Baldini, Elizabeth H., E-mail: ebaldini@partners.org; Abrams, Ross A.; Bosch, Walter

Purpose: The purpose of this study was to evaluate the variability in target volume and organ at risk (OAR) contour delineation for retroperitoneal sarcoma (RPS) among 12 sarcoma radiation oncologists. Methods and Materials: Radiation planning computed tomography (CT) scans for 2 cases of RPS were distributed among 12 sarcoma radiation oncologists with instructions for contouring gross tumor volume (GTV), clinical target volume (CTV), high-risk CTV (HR CTV: area judged to be at high risk of resulting in positive margins after resection), and OARs: bowel bag, small bowel, colon, stomach, and duodenum. Analysis of contour agreement was performed using the simultaneousmore » truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: Ten radiation oncologists contoured both RPS cases, 1 contoured only RPS1, and 1 contoured only RPS2 such that each case was contoured by 11 radiation oncologists. The first case (RPS 1) was a patient with a de-differentiated (DD) liposarcoma (LPS) with a predominant well-differentiated (WD) component, and the second case (RPS 2) was a patient with DD LPS made up almost entirely of a DD component. Contouring agreement for GTV and CTV contours was high. However, the agreement for HR CTVs was only moderate. For OARs, agreement for stomach, bowel bag, small bowel, and colon was high, but agreement for duodenum (distorted by tumor in one of these cases) was fair to moderate. Conclusions: For preoperative treatment of RPS, sarcoma radiation oncologists contoured GTV, CTV, and most OARs with a high level of agreement. HR CTV contours were more variable. Further clarification of this volume with the help of sarcoma surgical oncologists is necessary to reach consensus. More attention to delineation of the duodenum is also needed.« less

2014-07-01

Radiation therapy, a key component of cancer management, is required in more than half of new cancer patients, particularly in low- and middle-income countries (LMICs). The projected rise in cancer incidence over the next decades in LMICs will result in an increasing demand for radiation therapy services. Considering the present cancer incidence and that projected for 2020 (as listed in GLOBOCAN), we evaluated the current and anticipated needs for radiation therapy infrastructure and staffing by 2020 for each of the LMICs. Based on World Bank classification, 139 countries fall in the category of LMICs. Details of teletherapy, radiation oncologists, medical physicists, and radiation therapy technologists were available for 84 LMICs from the International Atomic Energy Agency-Directory of Radiotherapy Centres (IAEA-DIRAC) database. Present requirements and those for 2020 were estimated according to recommendations from the IAEA and European Society for Radiotherapy & Oncology (ESTRO-QUARTS). Only 4 of the 139 LMICs have the requisite number of teletherapy units, and 55 (39.5%) have no radiation therapy facilities at present. Patient access to radiation therapy in the remaining 80 LMICs ranges from 2.3% to 98.8% (median: 36.7%). By 2020, these 84 LMICs would additionally need 9169 teletherapy units, 12,149 radiation oncologists, 9915 medical physicists, and 29,140 radiation therapy technologists. Moreover, de novo radiation therapy facilities would have to be considered for those with no services. Twelve pragmatic steps are proposed for consideration at national and international levels to narrow the gap in radiation therapy access. Multipronged and coordinated action from all national and international stakeholders is required to develop realistic strategies to curb this impending global crisis. Copyright © 2014 Elsevier Inc.

Medical oncology in Japan has a relatively short history, with specialist certification starting in 2006, resulting in 867 certified medical oncologists as of 2014. Although the national government has appointed 397 Designated Cancer Care Hospitals, little is known about the actual situations of medical oncology services at these institutions. Questionnaires regarding the presence of a medical oncology department, the number of physicians in the department, the presence of certified medical oncologists and the degree of the medical oncologists' responsibilities for drug therapies in adults with solid cancers were sent to all 397 institutions between 21 January and 1 May 2013. The response rate was 68.0%. Among the responses, 39.4% of the institutions had medical oncology departments with a median of three physicians. Most of the medical oncology departments were primarily responsible, as evaluated according to patient number, for the treatment of limited disease categories. The medical oncologists were significantly more responsible for molecular-targeted therapy than for chemotherapy in head and neck cancer or for cytokine therapy in renal cell carcinoma. The wide variety of adverse events associated with molecular-targeted therapy might have enhanced the roles of medical oncologists. As the proportion of hospitals with a medical oncology department increased according to the number of certified medical oncologists working at the institution, cultivating medical oncologists seems to be an urgent task for advancing medical oncology in Japan. The present study provides fundamental data for the future development of medical oncology in Japan. The present study is to uncover the current situation of medical oncology in Japan. © The Author 2014. Published by Oxford University Press. All rights reserved.

Charles, Cathy; Gafni, Amiram; Whelan, Tim

2004-01-01

Abstract Background  Physicians are increasingly urged to practice shared decision‐making with their patients. Using a cross‐sectional survey, we explored the extent to which Ontario breast cancer specialists report practising shared decision‐making with their patients, their comfort level with this approach, and perceived barriers and facilitators to implementation. Participants and methods  All Ontario surgeons and oncologists (radiation and medical) treating women with early‐stage breast cancer were eligible for this study. Likert scales were used to measure physicians’ comfort level with and self‐reported use of different treatment decision‐making approaches as well as perceived barriers and facilitators to treatment decision‐making with patients. Results  The response rate was 79% for oncologists and 72% for surgeons. More physicians from each specialty (87% of oncologists and 89% of surgeons) expressed high levels of comfort with clinical example 4 (designed to illustrate a shared approach) than with any of the other examples presented (e.g. the informed and paternalistic approach). Similarly, more oncologists and surgeons reported that their usual approach to treatment decision‐making was like example 4 than like any other approach presented (56% of oncologists and 69% of surgeons, respectively). Comfort levels with example 4 for oncologists and surgeons were 31% and 20% higher, respectively, than the reported use of this approach. Lack of time and patient anxiety, patient lack of information and/or misinformation, and patient unwillingness or inability to participate were perceived by a substantial minority of both oncologists and surgeons as barriers to patient involvement in treatment decision‐making. Key facilitators identified included patients’ emotional readiness, support, information and trust in the physician. More research is needed to identify contextual, physician, patient, and interaction factors that will facilitate shared decision‐making in the medical encounter and help both parties create an environment conducive to implementing this approach to the extent desired.

Radiation oncologists in Russia face a number of unique professional difficulties including lack of standardized training and continuing medical education. To combat this, under the auspices of the Russian Society of Clinical Oncology (RUSSCO), our group has developed a series of ongoing in-person interactive contouring workshops that are held during the major Russian oncology conferences in Moscow, Russia. Since November 2016 during each workshop, we utilized a web-based open-access interactive three-dimensional contouring atlas as part of our didactics. We sought to determine the impact of this resource on radiation oncology practice in Russia. We distributed an IRB-approved web-based survey to 172 practicing radiation oncologists in Russia. We inquired about practice demographics, RUSSCO contouring workshop attendance, and the clinical use of open-access English language interactive contouring atlas (eContour). The survey remained open for 2 months until November 2017. Eighty radiation oncologists completed the survey with a 46.5% response rate. Mean number of years in practice was 13.7. Sixty respondents (75%) attended at least one RUSSCO contouring workshop. Of those who were aware of eContour, 76% were introduced during a RUSSCO contouring workshop, and 81% continue to use it in their daily practice. The greatest obstacles to using the program were language barrier (51%) and internet access (38%). Nearly 90% reported their contouring practices changed since they started using the program, particularly for delineation of clinical target volumes (57%) and/or organs at risk (46%). More than 97% found the clinical pearls/links to cooperative group protocols in the software helpful in their daily practice. The majority used the contouring program several times per month (43%) or several times per week (41%). Face-to-face contouring instruction in combination with open-access web-based interactive contouring resource had a meaningful impact on perceived quality of radiation oncology contours among Russian practitioners and has the potential to have applications worldwide.

To review currently available opportunities for medical students to supplement their standard medical education to prepare for a career in radiation oncology. Google and PubMed were used to identify existing clinical, health policy, and research programs for medical students in radiation oncology. In addition, results publicly available by the National Resident Matching Program were used to explore opportunities that successful radiation oncology applicants pursued during their medical education, including obtaining additional graduate degrees. Medical students can pursue a wide variety of opportunities before entering radiation oncology. Several national specialty societies, such as the American Society for Radiation Oncology and the Radiological Society of North America, offer summer internships for medical students interested in radiation oncology. In 2011, 30% of allopathic senior medical students in the United States who matched into radiation oncology had an additional graduate degree, including PhD, MPH, MBA, and MA degrees. Some medical schools are beginning to further integrate dedicated education in radiation oncology into the standard 4-year medical curriculum. To the authors' knowledge, this is the first comprehensive review of available opportunities for medical students interested in radiation oncology. Early exposure to radiation oncology and additional educational training beyond the standard medical curriculum have the potential to create more successful radiation oncology applicants and practicing radiation oncologists while also promoting the growth of the field. We hope this review can serve as guide to radiation oncology applicants and mentors as well as encourage discussion regarding initiatives in radiation oncology opportunities for medical students.

Brain metastasis and treatment

PubMed Central

Ahluwalia, Manmeet S.; Vogelbaum, Michael V.; Chao, Samuel T.

2014-01-01

Despite major therapeutic advances in the management of patients with systemic malignancies, management of brain metastases remains a significant challenge. These patients often require multidisciplinary care that includes surgical resection, radiation therapy, chemotherapy, and targeted therapies. Complex decisions about the sequencing of therapies to control extracranial and intracranial disease require input from neurosurgeons, radiation oncologists, and medical/neuro-oncologists. With advances in understanding of the biology of brain metastases, molecularly defined disease subsets and the advent of targeted therapy as well as immunotherapeutic agents offer promise. Future care of these patients will entail tailoring treatment based on host (performance status and age) and tumor (molecular cytogenetic characteristics, number of metastases, and extracranial disease status) factors. Considerable work involving preclinical models and better clinical trial designs that focus not only on effective control of tumor but also on quality of life and neurocognition needs to be done to improve the outcome of these patients.

Most medical schools in Spain (80%) offer undergraduate training in oncology. This education is highly variable in terms of content (theory and practical training), number of credits, and the medical specialty and departmental affiliation of the professors. Much of this variability is due to university traditions in the configuration of credits and programmes, and also to the structure of the hospital-based practical training. Undergraduate medical students deserve a more coherent and modern approach to education with a strong emphasis on clinical practice. Oncology is an interdisciplinary science that requires the input of professors from multiple specialties to provide the primary body of knowledge and skills needed to obtain both a theoretical and clinical understanding of cancer. Clinical skills should be a key focus due to their importance in the current model of integrated medical management and care. Clinical radiation oncology is a traditional and comprehensive hospital-based platform for undergraduate education in oncology. In Spain, a significant number (n = 80) of radiation oncology specialists have a contractual relationship to teach university courses. Most Spanish universities (80%) have a radiation oncologist on staff, some of whom are department chairs and many others are full professors who have been hired and promoted under competitive conditions of evaluation as established by the National Agency for Quality Evaluation. The Spanish Society of Radiation Oncology (SEOR) has identified new opportunities to improve undergraduate education in oncology. In this article, we discuss proposals related to theoretical (20 items) and practical clinical training (9 items). We also describe the SEOR University Forum, which is an initiative to develop a strategic plan to implement and organize cancer education at the undergraduate level in an interdisciplinary teaching spirit and with a strong contribution from radiation oncologists.

Neurosurgical interventions for patients with nasopharyngeal carcinoma: a single institution experience

PubMed Central

2013-01-01

Background Nasopharyngeal carcinoma (NPC) is a frequent head and neck cancer in southern China and Southeast Asia. The majority of NPC patients are managed by radiation oncologists, medical oncologists and head and neck surgeons. Actually, neurosurgical interventions are warranted under specific circumstances. In this article, we described our experience as neurosurgeons in the management of NPC patients. Methods Medical records of NPC patients who received neurosurgical procedure at Sun Yat-sen University Cancer Center were reviewed. Results Twenty-seven patients were identified. Among 27 cases, neurosurgical procedures were performed in 18 (66.7%) with radiation-induced temporal necrosis, 2 (7.4%) with radiation-induced sarcoma, 4 (14.8%) with synchronous NPC with primary brain tumors, 2 (7.4%) with recurrent NPC involving skull base, and 1 (3.7%) with metachronous skull eosinophilic granuloma, respectively. The diagnosis is challenging in specific cases and initial misdiagnoses were found in 6 (22.2%) patients. Conclusions For NPC patients with intracranial or skull lesions, the initial diagnosis can be occasionally difficult because of the presence or a history of NPC and related treatment. Unawareness of these entities can result in misdiagnosis and subsequent improper treatment. Neurosurgical interventions are necessary for the diagnosis and treatment for these patients.

Lambert, Carole; Gagnon, Robert; Nguyen, David; Charlin, Bernard

2009-01-01

Background The Script Concordance test (SCT) is a reliable and valid tool to evaluate clinical reasoning in complex situations where experts' opinions may be divided. Scores reflect the degree of concordance between the performance of examinees and that of a reference panel of experienced physicians. The purpose of this study is to demonstrate SCT's usefulness in radiation oncology. Methods A 90 items radiation oncology SCT was administered to 155 participants. Three levels of experience were tested: medical students (n = 70), radiation oncology residents (n = 38) and radiation oncologists (n = 47). Statistical tests were performed to assess reliability and to document validity. Results After item optimization, the test comprised 30 cases and 70 questions. Cronbach alpha was 0.90. Mean scores were 51.62 (± 8.19) for students, 71.20 (± 9.45) for residents and 76.67 (± 6.14) for radiation oncologists. The difference between the three groups was statistically significant when compared by the Kruskall-Wallis test (p < 0.001). Conclusion The SCT is reliable and useful to discriminate among participants according to their level of experience in radiation oncology. It appears as a useful tool to document the progression of reasoning during residency training. PMID:19203358

Since radiation oncologists make the treatment plan by prior experience, information about previous cases is helpful in planning the radiation treatment. We have developed an supporting system for the radiation therapy. The case-based reasoning method was implemented in order to search old treatments and images of past cases. This system evaluates similarities between the current case and all stored cases (case base). The portal images of the similar cases can be retrieved for reference images, as well as treatment records which show examples of the radiation treatment. By this system radiotherapists can easily make suitable plans of the radiation therapy. This system is useful to prevent inaccurate plannings due to preconceptions and/or lack of knowledge. Images were stored into magneto-optical disks and the demographic data is recorded to the hard disk which is equipped in the personal computer. Images can be displayed quickly on the radiotherapist's demands. The radiation oncologist can refer past cases which are recorded in the case base and decide the radiation treatment of the current case. The file and data format of magneto-optical disk is the IS&C format. This format provides the interchangeability and reproducibility of the medical information which includes images and other demographic data.

Purpose: To evaluate the actual work environment of radiation oncologists (ROs) in Japan in terms of working pattern, patient load, and quality of cancer care based on the relative time spent on patient care. Methods and Materials: In 2008, the Japanese Society of Therapeutic Radiology and Oncology produced a questionnaire for a national structure survey of radiation oncology in 2007. Data for full-time ROs were crosschecked with data for part-time ROs by using their identification data. Data of 954 ROs were analyzed. The relative practice index for patients was calculated as the relative value of care time per patient onmore » the basis of Japanese Blue Book guidelines (200 patients per RO). Results: The working patterns of RO varied widely among facility categories. ROs working mainly at university hospitals treated 189.2 patients per year on average, with those working in university hospitals and their affiliated facilities treating 249.1 and those working in university hospitals only treating 144.0 patients per year on average. The corresponding data were 256.6 for cancer centers and 176.6 for other facilities. Geographically, the mean annual number of patients per RO per quarter was significantly associated with population size, varying from 143.1 to 203.4 (p < 0.0001). There were also significant differences in the average practice index for patients by ROs working mainly in university hospitals between those in main and affiliated facilities (1.07 vs 0.71: p < 0.0001). Conclusions: ROs working in university hospitals and their affiliated facilities treated more patients than the other ROs. In terms of patient care time only, the quality of cancer care in affiliated facilities might be worse than that in university hospitals. Under the current national medical system, working patterns of ROs of academic facilities in Japan appear to be problematic for fostering true specialization of radiation oncologists.« less

Purpose: Trimodality therapy (chemoradiation and surgery) is the standard of care for stage II/III rectal cancer but nearly one third of patients do not receive radiation therapy (RT). We examined the relationship between the density of radiation oncologists and the travel distance to receipt of RT. Methods and Materials: A retrospective study based on the National Cancer Data Base identified 26,845 patients aged 18 to 80 years with stage II/III rectal cancer diagnosed from 2007 to 2010. Radiation oncologists were identified through the Physician Compare dataset. Generalized estimating equations clustering by hospital service area was used to examine the association betweenmore » geographic access and receipt of RT, controlling for patient sociodemographic and clinical characteristics. Results: Of the 26,845 patients, 70% received RT within 180 days of diagnosis or within 90 days of surgery. Compared with a travel distance of <12.5 miles, patients diagnosed at a reporting facility who traveled ≥50 miles had a decreased likelihood of receipt of RT (50-249 miles, adjusted odds ratio 0.75, P<.001; ≥250 miles, adjusted odds ratio 0.46; P=.002), all else being equal. The density level of radiation oncologists was not significantly associated with the receipt of RT. Patients who were female, nonwhite, and aged ≥50 years and had comorbidities were less likely to receive RT (P<.05). Patients who were uninsured but self-paid for their medical services, initially diagnosed elsewhere but treated at a reporting facility, and resided in Midwest had an increased the likelihood of receipt of RT (P<.05). Conclusions: An increased travel burden was associated with a decreased likelihood of receiving RT for patients with stage II/III rectal cancer, all else being equal; however, radiation oncologist density was not. Further research of geographic access and establishing transportation assistance programs or lodging services for patients with an unmet need might help decrease geographic barriers and improve the quality of rectal cancer care.« less

[Guideline on brain metastases: not a cookbook].

PubMed

Reijneveld, Jaap C

2011-01-01

The guideline 'Brain Metastases', which was revised on behalf of the Dutch Society for Neuro-Oncology (LWNO), provides an excellent overview of levels of scientific evidence on diagnosis and treatment of patients with parenchymal brain metastases of solid tumours. I would like to emphasize, however, that this guideline is not a cookbook for facilitating individual physicians to treat patients on their own. It is important that every patient suffering from brain metastases is discussed by a multidisciplinary tumour board consisting of at least a neurologist, a neurosurgeon, a medical oncologist, a radiation oncologist, a pathologist and a radiologist, and that several crucial questions need to be explicitly asked and answered about every single patient.

Optimal Use of Combined Modality Therapy in the Treatment of Esophageal Cancer.

PubMed

Shaikh, Talha; Meyer, Joshua E; Horwitz, Eric M

2017-07-01

Esophageal cancer is associated with a poor prognosis with 5-year survival rates of approximately 15% to 20%. Although patients with early stage disease may adequately be treated with a single modality, combined therapy typically consisting of neoadjuvant chemoradiation followed by esophagectomy is being adopted increasingly in patients with locally advanced disease. In patients who are not surgical candidates, definitive chemoradiation is the preferred treatment approach. All patients with newly diagnosed esophageal cancer should be evaluated in the multidisciplinary setting by a surgeon, radiation oncologist, and medical oncologist owing to the importance of each specialty in the management of these patients.

Beyond the Standard Curriculum: A Review of Available Opportunities for Medical Students to Prepare for a Career in Radiation Oncology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Agarwal, Ankit; DeNunzio, Nicholas J.; Ahuja, Divya

Purpose: To review currently available opportunities for medical students to supplement their standard medical education to prepare for a career in radiation oncology. Methods and Materials: Google and PubMed were used to identify existing clinical, health policy, and research programs for medical students in radiation oncology. In addition, results publicly available by the National Resident Matching Program were used to explore opportunities that successful radiation oncology applicants pursued during their medical education, including obtaining additional graduate degrees. Results: Medical students can pursue a wide variety of opportunities before entering radiation oncology. Several national specialty societies, such as the American Societymore » for Radiation Oncology and the Radiological Society of North America, offer summer internships for medical students interested in radiation oncology. In 2011, 30% of allopathic senior medical students in the United States who matched into radiation oncology had an additional graduate degree, including PhD, MPH, MBA, and MA degrees. Some medical schools are beginning to further integrate dedicated education in radiation oncology into the standard 4-year medical curriculum. Conclusions: To the authors' knowledge, this is the first comprehensive review of available opportunities for medical students interested in radiation oncology. Early exposure to radiation oncology and additional educational training beyond the standard medical curriculum have the potential to create more successful radiation oncology applicants and practicing radiation oncologists while also promoting the growth of the field. We hope this review can serve as guide to radiation oncology applicants and mentors as well as encourage discussion regarding initiatives in radiation oncology opportunities for medical students.« less

Smoking habits of radiotherapy patients: did the diagnosis of cancer make an impact and is there an opportunity to intervene?

To investigate the impact of a cancer diagnosis on smoking habits in patients receiving radiotherapy and assess the opportunity to intervene. One hundred consecutive patients were interviewed. They included patients newly diagnosed with cancer of any type and receiving radiotherapy. Detailed information was collected including smoking habits before and after the diagnosis, the timing of and reasons for any changes. We also asked about patients' view of the role of the radiation oncologist in smoking cessation and the opportunities for intervention. Analysis of results involved simple descriptive statistics. Although there were only 14 current smokers, only two had decided to quit. Five smokers decreased smoking, six did not change and one increased smoking. One non-smoker (1/34) took up smoking. Nearly all changes occurred within the first 30 days of diagnosis. Most (79%, 11/14) smokers believed that the treating radiation oncologist should discuss smoking cessation with their patients and that the ideal timing is at either the first consultation or when decisions about treatment have been finalised. The diagnosis of cancer can motivate patients to reduce smoking, but few quit altogether and a smaller number increase or even take up smoking. These changes occur early after receiving a diagnosis of cancer. Patients with a smoking history believed that the treating radiation oncologist should discuss smoking cessation with their patients and that the ideal timing is at the first consultation. The periodic nature of treatments and consultations at radiation oncology centres suggest there is the potential for an effective smoking cessation programme. © 2011 The Authors.

Social media and mobile technology are transforming the way in which young physicians are learning and practicing medicine. The true impact of such technologies has yet to be evaluated. We performed a nationwide cross-sectional survey to better assess how young radiation oncologists used these technologies. An online survey was sent out between April 24, 2013, and June 1, 2013. All residents attending the 2013 radiation oncology French summer course were invited to complete the survey. Logistic regressions were performed to assess predictors of use of these tools in the hospital on various clinical endpoints. In all, 131 of 140 (93.6%) French young radiation oncologists answered the survey. Of these individuals, 93% owned a smartphone and 32.8% owned a tablet. The majority (78.6%) of the residents owning a smartphone used it to work in their department. A total of 33.5% had more than 5 medical applications installed. Only 60.3% of the residents verified the validity of the apps that they used. In all, 82.9% of the residents had a social network account. Most of the residents in radiation oncology use their smartphone to work in their department for a wide variety of tasks. However, the residents do not consistently check the validity of the apps that they use. Residents also use social networks, with only a limited impact on their relationship with their patients. Overall, this study highlights the irruption and the risks of new technologies in the clinical practice and raises the question of a possible regulation of their use in the hospital.

Daroudi, Rajabali; Mirzania, Mehrzad; Zendehdel, Kazem

2016-01-01

Background: Although medical oncologists can have an important role in controlling the cost of cancer treatment, there is little information about their attitudes toward the cost of cancer treatment and the impact of cost on their treatment recommendations, especially in low- and middle-income countries (LMICs). In this study, we assessed the attitude of Iranian medical oncologists toward some economic aspects of new cancer drugs. Methods: We translated a questionnaire that was used in similar studies in the United States and Canada into Persian and modified it according to the local setting in Iran. The face and content validity of the questionnaire were assessed by oncologists before being used in the survey. We distributed the questionnaire and collected the data from 80 oncologists who participated in the 13th Annual Congress of the Iranian Society of Medical Oncology and Hematology (ISMOH). Results: Fifty-two oncologists participated in our study (a response rate of 65%). The majority of oncologists stated that drug costs and patient out-of-pocket (OOP) costs influence their treatment recommendations (92% and 94%, respectively). Most oncologists (70%) felt that they are ready enough to use cost-effectiveness information in their treatment decisions, and 74% believed that patients should only have access to cancer treatments that are cost-effective. Most oncologists agree that the government should have control over drug prices, and more use of cost‐effectiveness data is required for decision-making about cancer drug coverage. Ninety-one percent of oncologists said that they always or frequently discuss cancer treatment costs with their patients. Oncologists believed that academic groups (research centers and scientific societies) (81%) and the Ministry of Health (MoH) (43%) are the most eligible groups for determining whether a drug provides good value. Conclusion: Iranian medical oncologists are ready to participate in the health technology assessment and priority-setting process. This situation creates a unique opportunity for the government to rely on scientific societies and find an appropriate solution for the improvement of patients’ access to high-quality care.

2007-01-01

Despite growth of palliative care programs and evidence on the effectiveness of radiotherapy in palliating cancer symptoms, radiotherapy is probably underused in this setting. Radiation and medical oncologists and palliative medicine specialists were surveyed regarding the perceived role of palliative radiotherapy and barriers to its use. The survey was sent electronically to all physician members of the American Society for Therapeutic Radiology and Oncology (ASTRO) and the American Academy of Hospice and Palliative Medicine (AAHPM) and a random sample of American Society of Clinical Oncology (ASCO) members, with known e-mail addresses. Response rates were 27%, 14% and 26% for ASTRO, ASCO, and AAHPM respondents, respectively. Although most felt radiotherapy is an effective and important option for palliation of some common cancer symptoms, referrals for such therapy may be declining. Most agreed that radiation oncologists should be more involved in palliative care; however, multiple barriers were identified, such as poor reimbursement, emotional burden of care, insufficient training/knowledge, and the sense of unwillingness of others to share delivery of such services. Although multiple barriers limit optimal integration, most agree that there should be greater national and professional society efforts to promote the advancement of radiation oncology in the area of palliative care.

The management of patients with a cardiac implanted electronic device (CIED) receiving radiotherapy (RT) is challenging and requires a structured multidisciplinary approach. A consensus document is presented as a result of a multidisciplinary working group involving cardiac electrophysiologists, radiation oncologists and physicists in order to stratify the risk of patients with CIED requiring RT and approaching RT sessions appropriately. When high radiation doses and beam energy higher than 6MV are used, CIED malfunctions can occur during treatment. In our document, we reviewed the different types of RT and CIED behavior in the presence of ionizing radiations and electromagnetic interferences, from the cardiologist's, radiation oncologist's and medical physicist's point of view. We also reviewed in vitro and in vivo literature data and other national published guidelines on this issue so far. On the basis of literature data and consensus of experts, a detailed approach based on risk stratification and appropriate management of RT patients with CIEDs is suggested, with important implications for clinical practice.

Currently poster presentations offer a common visual medium for knowledge transfer by a wide range of health professionals. Our study aimed to determine the scientific importance of poster presentations for Medical and Radiation Oncologists. A survey form including 40 questions was distributed to a total of 131 oncologists experienced in poster presentations. One hundred completed survey forms were included in the study. Descriptive statistics and modified thematic analyses were performed on the responses. Overall 64% of the participants agreed that posters were a good medium for knowledge transfer. Some 88% agreed that concise and clear styled presentations would increase appealing interests for poster contents. Visual appearance was cited more influential than content of the subject; 70% of participants agreed that appearances of posters could help to draw more viewer attention. Of respondents, 63% believed that posters accompanied by their author were more attractive for congress attendees, and 33% of them declared that the halo effect of the poster presenter was also important. The present study indicated that intelligibility, appearance and visuality of posters are most important factors from the aspect of oncologist participants. Presenters must take into account these important points when preparing their academic posters.

A viable and sustainable medical oncology profession is integral for meeting the increasing demand for quality cancer care. The aim of this study was to explore the workforce-related experiences, perceptions and career expectations of early-career medical oncologists in Australia. A mixed-methods design, including a survey (n  =  170) and nested qualitative semistructured interviews (n  =  14) with early-career medical oncologists. Recruitment was through the Medical Oncology Group of Australia. Qualitative data were thematically analyzed and for the survey results, logistic regression modeling was conducted. Early-career medical oncologists experienced uncertainty regarding their future employment opportunities. The competitive job market has made them cautious about securing a preferred job leading to a perceived need to improve their qualifications through higher degree training and research activities. The following themes and trends were identified from the qualitative and quantitative analyses: age, career stage and associated early-career uncertainty; locale, professional competition and training preferences; participation in research and evolving professional expectations; and workload and career development opportunities as linked to career uncertainty. Perceived diminished employment opportunities in the medical oncology profession, and shifting expectations to be "more qualified," have increased uncertainty among junior medical oncologists in terms of their future career prospects. Structural factors relating to adequate funding of medical oncology positions may facilitate or inhibit progressive change in the workforce and its sustainability. Workforce planning and strategies informed by findings from this study will be necessary in ensuring that both the needs of cancer patients and of medical oncologists are met. © 2018 John Wiley & Sons Australia, Ltd.

Curative intent management of retroperitoneal sarcoma (RPS) requires gross total resection. Preoperative radiotherapy (RT) often is used as an adjuvant to surgery, but recurrence rates remain high. To enhance RT efficacy with acceptable tolerance, there is interest in delivering "boost doses" of RT to high-risk areas of gross tumor volume (HR GTV) judged to be at risk for positive resection margins. We sought to evaluate variability in HR GTV boost target volume delineation among collaborating sarcoma radiation and surgical oncologist teams. Radiation planning CT scans for three cases of RPS were distributed to seven paired radiation and surgical oncologist teams at six institutions. Teams contoured HR GTV boost volumes for each case. Analysis of contour agreement was performed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. HRGTV boost volume contour agreement between the seven teams was "substantial" or "moderate" for all cases. Agreement was best on the torso wall posteriorly (abutting posterior chest abdominal wall) and medially (abutting ipsilateral para-vertebral space and great vessels). Contours varied more significantly abutting visceral organs due to differing surgical opinions regarding planned partial organ resection. Agreement of RPS HRGTV boost volumes between sarcoma radiation and surgical oncologist teams was substantial to moderate. Differences were most striking in regions abutting visceral organs, highlighting the importance of collaboration between the radiation and surgical oncologist for "individualized" target delineation on the basis of areas deemed at risk and planned resection.

Expert Radiation Oncologist Interpretations of Involved-Site Radiation Therapy Guidelines in the Management of Hodgkin Lymphoma

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hoppe, Bradford S.; Hoppe, Richard T., E-mail: rhoppe@stanford.edu

Purpose: Recently, involved-site radiation therapy (ISRT) guidelines have been developed and published to replace the previous concept of involved-field radiation therapy for patients with lymphoma. However, these ISRT guidelines may be interpreted in different ways, posing difficulties for prospective clinical trials. This study reports survey results regarding interpretation of the ISRT guidelines. Methods and Materials: Forty-four expert lymphoma radiation oncologists were asked to participate in a survey that included 7 different cases associated with 9 questions. The questions pertained to ISRT contouring and asked respondents to choose between 2 different answers (no “correct” answer) and a third write-in option allowed.more » Results: Fifty-two percent of those surveyed responded to the questionnaire. Among those who responded, 72% have practiced for >10 years, 46% have treated >20 Hodgkin lymphoma cases annually, and 100% were familiar with the ISRT concept. Among the 9 questions associated with the 7 cases, 3 had concordance among the expert radiation oncologists of greater than 70%. Six of the questions had less than 70% concordance (range, 56%-67%). Conclusions: Even among expert radiation oncologists, interpretation of ISRT guidelines is variable. Further guidance for ISRT field design will be needed to reduce variability among practicing physicians.« less

Multiple studies suggest that radiation dose to the area of the brainstem called the “dorsal vagal complex (DVC)” influences the frequency of nausea and vomiting during radiotherapy. The purpose of this didactic article is to describe the step-by-step process that we use to contour the general area of the DVC on axial computed tomography (CT) images as would be done for radiotherapy planning. The contouring procedure that we describe for contouring the area of the DVC is useful to medical dosimetrists and radiation oncologists.

The frequency and sophistication of health care reimbursement auditing has progressed rapidly in recent years, leaving many oncologists wondering whether their private practices would survive a full-scale Office of the Inspector General (OIG) investigation. The Medicare Part B claims database provides a rich source of information for physicians seeking to understand how their billing practices measure up to their peers, both locally and nationally. This database was dissected by a team of cancer specialists to uncover important benchmarks related to targeted auditing. All critical Medicare charges, payments, denials, and service ratios in this article were derived from the full 2010 Medicare Part B claims database. Relevant claims were limited by using Medicare provider specialty codes 83 (hematology/oncology) and 90 (medical oncology), with an emphasis on claims filed from the physician office place of service (11). All charges, denials, and payments were summarized at the Current Procedural Terminology code level to drive practice benchmarking standards. A careful analysis of this data set, combined with the published audit priorities of the OIG, produced germane benchmarks from which medical oncologists can monitor, measure and improve on common areas of billing fraud, waste or abuse in their practices. Part II of this series and analysis will focus on information pertinent to radiation oncologists. PMID:23598847

The American Society of Clinical Oncology (ASCO) 2007 workforce report projected US oncologist shortages by 2020. Intervening years have witnessed shifting trends in both supply and demand, demonstrating the need to capture data in a dynamic manner. The ASCO Workforce Information System (WIS) provides an infrastructure to update annually emerging characteristics of US oncologists (medical oncologists, hematologist/oncologists, and hematologists). Several possible data sources exist to capture the number of oncologists in the United States. The WIS primarily uses the American Medical Association Physician Masterfile database because it provides detailed demographics. This analysis also compares total counts of oncologists from American Board of Internal Medicine (ABIM) certification reports, the National Provider Identifier (NPI) database, and Medicare Physician Compare data. The analysis also examines geographic distribution of oncologists by age and US population data. For each of the data sources, we pulled 2013 data. The Masterfile identified 13,409 oncologists. ABIM reported 13,757 oncologists. NPI listed 11,664 oncologists. Physician Compare identified 11,343 oncologists. Mapping of these data identifies distinct areas (primarily in central United States, Alaska, and Hawaii) that seem to lack ready access to oncologists. Efforts to survey oncologists about practice patterns will help determine if productivity and service delivery will change significantly. ASCO is committed to tracking oncologist supply and demand, as well as to providing timely analysis of strategies that will help address any shortages that may occur in specific regions or practice settings.

A significant physician shortage has been projected to occur by 2025, and demand for oncologists is expected to outpace supply to an even greater degree. In response to this, many have called to increase the number of radiation oncology residency positions. The purpose of this study is to evaluate National Resident Matching Program (NRMP) data for the number of residency positions between 2004 and 2015 as well as the number and caliber of applicants for those positions and to compare radiation oncology to all residency specialties. NRMP data for all specialties participating in the match, including radiation oncology, were assessed over time examining the number of programs participating in the match, the number of positions offered, and the ratio of applicants to positions in the match from 2004 to 2015. From 2004 to 2015, the number of total programs participating in the match has increased by 26.7%, compared to the increase of 28.6% in the number of radiation oncology programs from during the same time period. The total number of positions offered in the match increased by 53.4%, whereas radiation oncology positions increased by 56.3%, during the same time period. The ratio of applicants (defined as those selecting a specialty as their first or only choice) to positions for all specialties has fluctuated over this time period and has gone from 1.21 to 1.15, whereas radiation oncology experienced a decrease from 1.45 to 1.14. NRMP data suggest that senior medical student applications to radiation oncology are decreasing compared to those of other specialties. If we hope to continue to attract the best and brightest to enter our field, we must continue to support early exposure to radiation oncology, positive educational experiences, and dedicated mentorship to interested medical students.

Teshima, Teruki; Numasaki, Hodaka; Shibuya, Hitoshi

2008-09-01

Purpose: To evaluate the structure of radiation oncology in Japan in terms of equipment, personnel, patient load, and geographic distribution to identify and improve any deficiencies. Methods and Materials: A questionnaire-based national structure survey was conducted between March 2006 and February 2007 by the Japanese Society of Therapeutic Radiology and Oncology. These data were analyzed in terms of the institutional stratification of the Patterns of Care Study. Results: The total numbers of new cancer patients and total cancer patients (new and repeat) treated with radiotherapy in 2005 were estimated at approximately 162,000 and 198,000, respectively. In actual use were 765more » linear accelerators, 11 telecobalt machines, 48 GammaKnife machines, 64 {sup 60}Co remote-controlled after-loading systems, and 119 {sup 192}Ir remote-controlled after-loading systems. The linear accelerator systems used dual-energy function in 498 systems (65%), three-dimensional conformal radiotherapy in 462 (60%), and intensity-modulated radiotherapy in 170 (22%). There were 426 Japanese Society of Therapeutic Radiology and Oncology-certified radiation oncologists, 774 full-time equivalent radiation oncologists, 117 medical physicists, and 1,635 radiation therapists. Geographically, a significant variation was found in the use of radiotherapy, from 0.9 to 2.1 patients/1,000 population. The annual patient load/FTE radiation oncologist was 247, exceeding the Blue Book guidelines level. Patterns of Care Study stratification can clearly discriminate the maturity of structures according to their academic nature and caseload. Conclusions: The Japanese structure has clearly improved during the past 15 years in terms of equipment and its use, although the shortage of manpower and variations in maturity disclosed by this Patterns of Care Study stratification remain problematic. These constitute the targets for nationwide improvement in quality assurance and quality control.« less

Health providers' implicit racial bias negatively affects communication and patient reactions to many medical interactions. However, its effects on racially discordant oncology interactions are largely unknown. Thus, we examined whether oncologist implicit racial bias has similar effects in oncology interactions. We further investigated whether oncologist implicit bias negatively affects patients' perceptions of recommended treatments (i.e., degree of confidence, expected difficulty). We predicted oncologist implicit bias would negatively affect communication, patient reactions to interactions, and, indirectly, patient perceptions of recommended treatments. Participants were 18 non-black medical oncologists and 112 black patients. Oncologists completed an implicit racial bias measure several weeks before video-recorded treatment discussions with new patients. Observers rated oncologist communication and recorded interaction length of time and amount of time oncologists and patients spoke. Following interactions, patients answered questions about oncologists' patient-centeredness and difficulty remembering contents of the interaction, distress, trust, and treatment perceptions. As predicted, oncologists higher in implicit racial bias had shorter interactions, and patients and observers rated these oncologists' communication as less patient-centered and supportive. Higher implicit bias also was associated with more patient difficulty remembering contents of the interaction. In addition, oncologist implicit bias indirectly predicted less patient confidence in recommended treatments, and greater perceived difficulty completing them, through its impact on oncologists' communication (as rated by both patients and observers). Oncologist implicit racial bias is negatively associated with oncologist communication, patients' reactions to racially discordant oncology interactions, and patient perceptions of recommended treatments. These perceptions could subsequently directly affect patient-treatment decisions. Thus, implicit racial bias is a likely source of racial treatment disparities and must be addressed in oncology training and practice. © 2016 by American Society of Clinical Oncology.

Use of adjuvant chemotherapy (CT) and radiotherapy (RT) in incompletely resected (R1) early stage Non-Small Cell Lung Cancer (NSCLC): a European survey conducted by the European Society for Medical Oncology (ESMO) young oncologists committee.

Early stage Non-Small Cell Lung Cancer (NSCLC) is potentially curable with surgery. ESMO guidelines recommend cisplatin-based adjuvant chemotherapy (CT) for completely resected stage II-III NSCLC. There is limited evidence for the use of adjuvant CT and/or radiotherapy (RT) in incompletely resected (R1) early stage NSCLC. A European survey of thoracic oncologists was conducted to evaluate use of adjuvant CT and RT for R1-resected NSCLC and to identify factors influencing treatment decisions. Demographics and information on clinical stage, regimens, cycles planned, radiotherapy sites, multidisciplinary management and discussion about inconclusive evidence with the patient were collected. Univariate and multivariate analyses were performed. 768 surveys were collected from 41 European countries. 82.9% of participants were medical oncologists; 49.3% ESMO members; 37.1% based in University Hospitals; 32.6% practicing oncology for over 15 years and 81.4% active in research. 91.4% of participants prescribed adjuvant CT and mostly cisplatin/vinorelbine (81.2%) or cisplatin/gemcitabine (42.9%). 85% discussed limited clinical evidence with the patient. In the univariate analysis, a statistically significant association with CT prescription was found for medical oncology specialty (p<0.001), ESMO membership (p<0.001), activity in clinical research (p=0.002) and increased frequency of ESMO guidelines consultation (p for trend <0.001). 48.3% of participants prescribed adjuvant RT and its prescription were associated with radiation oncology specialty (p<0.001), not being an ESMO member (p<0.001), years practicing specialty (p for trend=0.001), workload of lung cancer patients (p for trend=0.027) and decreased frequency in consulting ESMO guidelines (p<0.001). In the multivariate analysis, medical oncology and radiation oncology were the best discriminator for prescription of adjuvant CT and RT, respectively. This survey demonstrates that adjuvant CT and RT are commonly used in clinical practice for R1-resected NSCLC despite limited evidence. Prospective trials are necessary to clarify optimal management in this setting. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Radiation Oncology in Undergraduate Medical Education: A Literature Review

Dennis, Kristopher E.B., E-mail: kdennis@bccancer.bc.c; Duncan, Graeme

2010-03-01

Purpose: To review the published literature pertaining to radiation oncology in undergraduate medical education. Methods and Materials: Ovid MEDLINE, Ovid MEDLINE Daily Update and EMBASE databases were searched for the 11-year period of January 1, 1998, through the last week of March 2009. A medical librarian used an extensive list of indexed subject headings and text words. Results: The search returned 640 article references, but only seven contained significant information pertaining to teaching radiation oncology to medical undergraduates. One article described a comprehensive oncology curriculum including recommended radiation oncology teaching objectives and sample student evaluations, two described integrating radiation oncologymore » teaching into a radiology rotation, two described multidisciplinary anatomy-based courses intended to reinforce principles of tumor biology and radiotherapy planning, one described an exercise designed to test clinical reasoning skills within radiation oncology cases, and one described a Web-based curriculum involving oncologic physics. Conclusions: To the authors' knowledge, this is the first review of the literature pertaining to teaching radiation oncology to medical undergraduates, and it demonstrates the paucity of published work in this area of medical education. Teaching radiation oncology should begin early in the undergraduate process, should be mandatory for all students, and should impart knowledge relevant to future general practitioners rather than detailed information relevant only to oncologists. Educators should make use of available model curricula and should integrate radiation oncology teaching into existing curricula or construct stand-alone oncology rotations where the principles of radiation oncology can be conveyed. Assessments of student knowledge and curriculum effectiveness are critical.« less

With the growing concerns about overtreatment in prostate cancer, the extent to which radiation oncologists and urologists perceive active surveillance (AS) as effective and recommend it to patients are unknown. To assess opinions of radiation oncologists and urologists about their perceptions of AS and treatment recommendations for low-risk prostate cancer. National survey of specialists. Radiation oncologists and urologists practicing in the United States. A total of 1366 respondents were asked whether AS was effective and whether it was underused nationally, whether their patients were interested in AS, and treatment recommendations for low-risk prostate cancer. Pearson's χ test and multivariate logistic regression were used to test for differences in physician perceptions on AS and treatment recommendations. Overall, 717 (52.5%) of physicians completed the survey with minimal differences between specialties (P=0.92). Although most physicians reported that AS is effective (71.9%) and underused in the United States (80.0%), 71.0% stated that their patients were not interested in AS. For low-risk prostate cancer, more physicians recommended radical prostatectomy (44.9%) or brachytherapy (35.4%); fewer endorsed AS (22.1%). On multivariable analysis, urologists were more likely to recommend surgery [odds ratio (OR): 4.19; P<0.001] and AS (OR: 2.55; P<0.001), but less likely to recommend brachytherapy (OR: 0.13; P<0.001) and external beam radiation therapy (OR: 0.11; P<0.001) compared with radiation oncologists. Most prostate cancer specialists in the United States believe AS effective and underused for low-risk prostate cancer, yet continue to recommend the primary treatments their specialties deliver.

Purpose: To analyze survey information regarding mentorship practices and cross-correlate the results with objective metrics of academic productivity among academic radiation oncologists at US Accreditation Council for Graduate Medical Education (ACGME)-accredited residency training programs. Methods and Materials: An institutional review board-approved survey for the Radiation Oncology Academic Development and Mentorship Assessment Project (ROADMAP) was sent to 1031 radiation oncologists employed at an ACGME-accredited residency training program and administered using an international secure web application designed exclusively to support data capture for research studies. Data collected included demographics, presence of mentorship, and the nature of specific mentoring activities. Productivity metrics, includingmore » number of publications, number of citations, h-index, and date of first publication, were collected for each survey respondent from a commercially available online database, and m-index was calculated. Results: A total of 158 academic radiation oncologists completed the survey, 96 of whom reported having an academic/scientific mentor. Faculty with a mentor had higher numbers of publications, citations, and h- and m-indices. Differences in gender and race/ethnicity were not associated with significant differences in mentorship rates, but those with a mentor were more likely to have a PhD degree and were more likely to have more time protected for research. Bivariate fit regression modeling showed a positive correlation between a mentor's h-index and their mentee's h-index (R{sup 2} = 0.16; P<.001). Linear regression also showed significant correlates of higher h-index, in addition to having a mentor (P=.001), included a longer career duration (P<.001) and fewer patients in treatment (P=.02). Conclusions: Mentorship is widely believed to be important to career development and academic productivity. These results emphasize the importance of identifying and striving to overcome potential barriers to effective mentorship.« less

Medical physics plays an essential role in modern medicine. This is particularly evident in cancer care where medical physicists are involved in radiotherapy treatment planning and quality assurance as well as in imaging and radiation protection. Due to the large variety of tasks and interests, medical physics is often subdivided into specialties such as radiology, nuclear medicine and radiation oncology medical physics. However, even within their specialty, the role of radiation oncology medical physicists (ROMPs) is diverse and varies between different societies. Therefore, a questionnaire was sent to leading medical physicists in most countries/areas in the Asia/Pacific region to determine the education, role and status of medical physicists. Answers were received from 17 countries/areas representing nearly 2800 radiation oncology medical physicists. There was general agreement that medical physicists should have both academic (typically at MSc level) and clinical (typically at least 2 years) training. ROMPs spent most of their time working in radiotherapy treatment planning (average 17 hours per week); however radiation protection and engineering tasks were also common. Typically, only physicists in large centres are involved in research and teaching. Most respondents thought that the workload of physicists was high, with more than 500 patients per year per physicist, less than one ROMP per two oncologists being the norm, and on average, one megavoltage treatment unit per medical physicist. There was also a clear indication of increased complexity of technology in the region with many countries/areas reporting to have installed helical tomotherapy, IMRT (Intensity Modulated Radiation Therapy), IGRT (Image Guided Radiation Therapy), Gamma-knife and Cyber-knife units. This and the continued workload from brachytherapy will require growing expertise and numbers in the medical physics workforce. Addressing these needs will be an important challenge for the future.

Castro, J.R.

1994-04-01

The potential of heavy ion therapy for clinical use in cancer therapy stems from the biological parameters of heavy charged particles, and their precise dose localization. Biologically, carbon, neon and other heavy ion beams (up to about silicon) are clinically useful in overcoming the radioresistance of hypoxic tumors, thus increasing biological effectiveness relative to low-LET x-ray or electron beams. Cells irradiated by heavy ions show less variation in cell-cycle related radiosensitivity and decreased repair of radiation injury. The physical parameters of these heavy charged particles allow precise delivery of high radiation doses to tumors while minimizing irradiation of normal tissues.more » Clinical use requires close interaction between radiation oncologists, medical physicists, accelerator physicists, engineers, computer scientists and radiation biologists.« less

Bekelman, Justin E.; Zelefsky, Michael J.; Jang, Thomas L.

2007-12-01

Purpose: To characterize the variation in adherence to quality measures of external beam radiotherapy (EBRT) for localized prostate cancer and its relation to patient and provider characteristics in a population-based, representative sample of U.S. men. Methods and Materials: We evaluated EBRT quality measures proposed by a RAND expert panel of physicians among men aged {>=}65 years diagnosed between 2000 and 2002 with localized prostate cancer and treated with primary EBRT using data from the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare program. We assessed the adherence to five EBRT quality measures that were amenable to analysis using SEER-Medicare data: (1)more » use of conformal RT planning; (2) use of high-energy (>10-MV) photons; (3) use of custom immobilization; (4) completion of two follow-up visits with a radiation oncologist in the year after therapy; and (5) radiation oncologist board certification. Results: Of the 11,674 patients, 85% had received conformal RT planning, 75% had received high-energy photons, and 97% had received custom immobilization. One-third of patients had completed two follow-up visits with a radiation oncologist, although 91% had at least one visit with a urologist or radiation oncologist. Most patients (85%) had been treated by a board-certified radiation oncologist. Conclusions: The overall high adherence to EBRT quality measures masked substantial variation in geography, socioeconomic status in the area of residence, and teaching affiliation of the RT facility. Future research should examine the reasons for the variations in these measures and whether the variation is associated with important clinical outcomes.« less

The impact of RTOG 0614 and RTOG 0933 trials in routine clinical practice: The US Survey of Utilization of Memantine and IMRT planning for hippocampus sparing in patients receiving whole brain radiotherapy for brain metastases.

2016-03-01

Two recent clinical trials, phase III RTOG 0614 and phase II RTOG 0933, showed some effectiveness of Memantine and IMRT planning for hippocampus sparing, among patients receiving whole brain radiotherapy (WBRT) for brain metastases; however, their use in routine clinical practice is unknown. A survey was sent to 1933 radiation oncologists in the US. Data collected included utilization of Memantine and hippocampus sparing, reasons for adoption and non-adoption, and demographic variables. A total of 196 radiation oncologists responded to the survey, with 64% reporting using Memantine in almost none of the patients receiving WBRT for brain metastases, and only 11% considering Memantine for <10% of their patients. The most common reason for not using Memantine was a poor patient performance status, and limited life expectancy. Likewise, 56% of radiation oncologists would not change their clinical practice to include hippocampus sparing IMRT in patients receiving WBRT based on the results of RTOG 0933. Further validation of hippocampus sparing in a phase III trial was supported by 71% of radiation oncologists, whereas further exploration of Memantine for this purpose in a phase III trial was supported by 42%. At this time, the majority of surveyed radiation oncologists in the US do not use Memantine, or IMRT planning for hippocampus sparing in patients receiving WBRT. Further validation of the hippocampus sparing concept in a phase III trial was supported, before adopting it in routine clinical practice. Copyright © 2015 Elsevier Inc. All rights reserved.

There is significant variation in access to palliative care. We examined the pattern of outpatient palliative care referral among thoracic medical oncologists and identified oncologist characteristics associated with greater referral. We retrieved data on all patients who died of advanced thoracic malignancies at our institution between January 1, 2007, and December 31, 2012. Using median as a cutoff, we defined two groups (high-referring and low-referring oncologists) based on their frequency of referral. We examined various oncologist- and patient-related characteristics associated with outpatient referral. Of 1,642 decedents, 444 (27%) had an outpatient palliative care referral. The median proportion of referral among 26 thoracic oncologists was 30% (range 9%-45%; median proportion of high-referring 37% vs. low-referring 24% when divided into two groups at median). High-referring oncologists were significantly younger (age 45 vs. 56) than low-referring oncologists; they were also significantly more likely to refer patients earlier (median interval between oncology consultation and palliative care consultation 90 days vs. 170 days) and to refer those without metastatic disease (7% vs. 2%). In multivariable mixed-effect logistic regression, younger oncologists (odds ratio [OR] = 0.97 per year increase, 95% confidence interval [CI] 0.95-0.995), younger patients (OR = 0.98 per year increase, 95% CI 0.97-0.99), and nonmetastatic disease status (OR = 0.48, 95% CI 0.29-0.78) were significantly associated with outpatient palliative care referral. The pattern of referral to outpatient palliative care varied widely among thoracic oncologists. Younger oncologists were not only referring a higher proportion of patients, but also referring patients earlier in the disease trajectory. This retrospective cohort study found that younger thoracic medical oncologists were significantly more likely to refer patients to outpatient palliative care and to do so earlier in the disease trajectory compared with older oncologists, even after adjusting for other known predictors such as patient demographics. The findings highlight the role of education to standardize palliative care access and imply that outpatient palliative care referral is likely to continue to increase with a shifting oncology workforce. © AlphaMed Press 2018.

To develop a reproducible definition for each mediastinal lymph node station based on the new TNM classification for lung cancer. This paper proposes an atlas using the new international lymph node map used in the seventh edition of the TNM classification for lung cancer. Four radiation oncologists and 1 diagnostic radiologist were involved in the project to put forward a reproducible radiologic description for the lung lymph node stations. The International Association for the Study of Lung Cancer lymph node definitions for stations 1 to 11 have been described and illustrated on axial computed tomographic scan images using a certified radiotherapy planning system. This atlas will assist both diagnostic radiologists and radiation oncologists in accurately defining the lymph node stations on computed tomographic scan in patients diagnosed with lung cancer.

De Jesús, M.; Trujillo-Zamudio, F. E.

2010-12-01

A building project of Radiotherapy & Nuclear Medicine services (diagnostic and therapy), within an Integral Oncology Center (IOC), requires interdisciplinary participation of architects, biomedical engineers, radiation oncologists and medical physicists. This report focus on the medical physicist role in designing, building and commissioning stages, for the final clinical use of an IOC at the Oaxaca High Specialization Regional Hospital (HRAEO). As a first step, during design stage, the medical physicist participates in discussions about radiation safety and regulatory requirements for the National Regulatory Agency (called CNSNS in Mexico). Medical physicists propose solutions to clinical needs and take decisions about installing medical equipment, in order to fulfill technical and medical requirements. As a second step, during the construction stage, medical physicists keep an eye on building materials and structural specifications. Meanwhile, regulatory documentation must be sent to CNSNS. This documentation compiles information about medical equipment, radioactivity facility, radiation workers and nuclear material data, in order to obtain the license for the linear accelerator, brachytherapy and nuclear medicine facilities. As a final step, after equipment installation, the commissioning stage takes place. As the conclusion, we show that medical physicists are essentials in order to fulfill with Mexican regulatory requirements in medical facilities.

Mouth and pharyngeal cancers account for approximately 6% of cancers worldwide. Radiotherapy is one of the means of treatment of head and neck cancer. Consultation with a dental team experienced in caring for patients undergoing treatment for head and neck cancer will improve the quality of life of such patients. To evaluate the attitude of oncologists toward dental consultation to patients planning for/prior to/undergoing/post radiation therapy for head and neck cancers and to evaluate the number of radiation oncologists who encounter oral complaints and consider worth referring to a dentist. A questionnaire-based study was carried out following mailing of covering letter and self-administered questionnaire comprising 11 items, to 25 radiation oncology centers selected in India based on convenient sampling. Out of the 25 centers, we received response from 20 centers with 60 completely filled questionnaires. Five centers did not respond for further correspondences. The study indicated a need for awareness and education among radiation oncologists regarding dental consultation in patients planned/undergoing /post radiation therapy for head and neck cancer.

Oncologists must have empathy when breaking bad news to patients who have incurable advanced cancer, and the level of empathy often depends on various individual characteristics. This study aimed to clarify the relationship between these characteristics and empathic behavior in Japanese oncologists. We videotaped consultations in which oncologists conveyed news of incurable advanced cancer to simulated patients. Oncologists' empathetic behaviors were coded, and regression analysis was performed to determine the existence of any relationships with factors such as age, sex, and specialism. Sixty oncologists participated. In a multivariate model, only age was related to the empathy score (r=0.406, p=0.033); younger oncologists scored higher than did older oncologists. We found that empathic behaviors were more frequent in younger oncologists. This information could be useful in determining the best approach for implementing future empathy and communication training programs for experienced oncologists in Japanese medical institutions.

Purpose: Inconsistencies in contouring target structures can undermine the precision of conformal radiation therapy (RT) planning and compromise the validity of clinical trial results. This study evaluated the impact of guidelines on consistency in target volume contouring for partial breast RT planning. Methods and Materials: Guidelines for target volume definition for partial breast radiation therapy (PBRT) planning were developed by members of the steering committee for a pilot trial of PBRT using conformal external beam planning. In phase 1, delineation of the breast seroma in 5 early-stage breast cancer patients was independently performed by a 'trained' cohort of four radiationmore » oncologists who were provided with these guidelines and an 'untrained' cohort of four radiation oncologists who contoured without guidelines. Using automated planning software, the seroma target volume (STV) was expanded into a clinical target volume (CTV) and planning target volume (PTV) for each oncologist. Means and standard deviations were calculated, and two-tailed t tests were used to assess differences between the 'trained' and 'untrained' cohorts. In phase 2, all eight radiation oncologists were provided with the same contouring guidelines, and were asked to delineate the seroma in five new cases. Data were again analyzed to evaluate consistency between the two cohorts. Results: The 'untrained' cohort contoured larger seroma volumes and had larger CTVs and PTVs compared with the 'trained' cohort in three of five cases. When seroma contouring was performed after review of contouring guidelines, the differences in the STVs, CTVs, and PTVs were no longer statistically significant. Conclusion: Guidelines can improve consistency among radiation oncologists performing target volume delineation for PBRT planning.« less

The objective was to query how specialty influences treatment recommendations for high-risk prostate cancer in 3 clinical settings: upfront management, postoperative management, and management of biochemical recurrences (BCRs) after radiotherapy (RT). We hypothesized that specialty bias would manifest in all settings, trumping available evidence. A survey of practicing urologists and radiation oncologists was distributed through electronic mail. Questions pertained to upfront management, postoperative treatment, and local salvage for postradiation BCRs. The associations between 26 selected categorical responses and specialty were assessed using multivariate logistic regression. Training level/expertise, practice setting, percentage of consultation caseload consisting of prostate cancer, and nationality were set as effect modifiers. One thousand two hundred fifty-three physicians (846 radiation oncologists and 407 urologists) completed the survey. Radiation oncologists were more likely to recommend adjuvant RT and consider it to be underutilized, and more likely to recommend salvage RT at lower prostate-specific antigen thresholds (P<0.0001). Urologists were more likely to recommend salvage radical prostatectomy or cryoablation for local salvage after RT, whereas radiation oncologists were more likely to recommend RT-based modalities and more likely to report that local salvage was underutilized after RT (P<0.0001). Urologists were more likely to report that upfront radical prostatectomy was a better definitive treatment (P<0.0001), whereas radiation oncologists were more likely to report the opposite (P=0.005). Specialty biases permeate recommendations for upfront management and management in the postoperative and post-RT BCR setting, irrespective of available evidence. These data reveal the critical need for multidisciplinary clinics and cross-specialty training as potential solutions for overcoming specialty bias.

This national survey has measured the working conditions, work engagement, job strain, burn out, and the negative work-home interaction among Belgian radiation oncologists with validated questionnaires. In fact, previous studies had in general shown an interest to burn out and its association with working conditions among oncology workers, but not focused on radiation oncologists in particular. Moreover, few studies concerned work engagement and its association with working conditions although this could be important in preventing burn out. We used the WOrking Conditions and Control Questionnaire, the Positive and Negative Occupational States Inventory, the Maslach Burn out Inventory, and the negative work-home interaction subscale of the Survey Work-home Interaction Nijmegen. One open question asked about problematic job situations. Sixty-six radiation oncologists participated (30% response rate). Median scores of most of working conditions corresponded to normal scores. Control over time management (45.8) was close to low score, while control over future (60.9) was high. Median score of job strain (48.9) was normal, whereas median score of work engagement (60) was high. Median score of burn out was low. The mean of negative work-home interactions (1.1) was higher than the mean of 0.84 in a reference sample (t=4.3; P<0.001). The most frequent problematic situations referred to work organization (e.g. time pressure) and specific resources (e.g. chief support). Radiation oncologists showed a very high level of work engagement and experienced several job resources. However, some resources (as supervisor support) were missing and needed to be developed. These results were discussed in the context of motivational process described in the Job Demands-Resources Model. Copyright © 2014 Société française de radiothérapie oncologique (SFRO).

To review the current management, outline recent advances and address controversies in the management of hepatocellular carcinoma (HCC). The treatment of HCC is multidisciplinary involving hepatologists, surgeons, medical oncologists, radiation oncologists, radiologists, interventional radiologists, and other disciplines. Each of these disciplines brings its unique perspective and differing opinions that add to controversies in the management of HCC. A focused literature review was performed to identify recent studies on the management of HCC and thereby summarize relevant information on the various therapeutic modalities and controversies involved in the treatment of HCC. The main treatment algorithms continue to rely on hepatic resection or transplantation with controversies involving patients harboring early stage disease and borderline hepatic function. The other treatment strategies include locoregional therapies, radiation, and systemic therapy used alone or in combination with other treatment modalities. Recent advances in locoregional therapies, radiation, and systemic therapies have provided better therapeutic options with curative intent potential for some locoregional therapies. Further refinements in combination therapies such as algorithms consisting of locoregional therapies and systemic or radiation therapies are likely to add additional options and improve survival. The management of HCC has witnessed significant strides with advances in existing options and introduction of several new treatment modalities of various combinations. Further refinements in these treatment options combined with enrollment in clinical trials are essential to improve the management and outcomes of patients with HCC.

Macklis, Roger M.; Pohlman, Brad

Purpose: The aim of this study was to review advances in radioimmunotherapy (RIT) for non-Hodgkin's lymphoma (NHL) and to discuss the role of Radiation oncologist in administering this important new form of biologically targeted radiotherapy. Methods and Materials: A review of articles and abstracts on the clinical efficacy, safety, and radiation safety of yttrium Y 90 ({sup 9}Y) ibritumomab tiuxetan (Zevalin) and iodine I 131 tositumomab (Bexxar) was performed. Results: The clinical efficacy of RIT in NHL has been shown in numerous clinical trials of {sup 9}Y ibritumomab tiuxetan and {sup 131}I tositumomab. Both agents have produced significant responses inmore » patients with low-grade, follicular, or transformed NHL, including patients with disease that had not responded or had responded poorly to previous chemotherapy or immunotherapy. Reversible toxicities such as neutropenia, thrombocytopenia, and anemia are the most common adverse events with both agents. Conclusions: Radioimmunotherapy is safe and effective in many patients with B-cell NHL. {sup 9}Y ibritumomab tiuxetan and {sup 131}I tositumomab can produce clinically meaningful and durable responses even in patients in whom chemotherapy has failed. Treatment with RIT requires a multispecialty approach and close communication between Radiation oncologist and other members of the treatment team. Radiation oncologist plays an important role in treating patients with RIT and monitoring them for responses and adverse events after treatment.« less

Purpose Health providers’ implicit racial bias negatively affects communication and patient reactions to many medical interactions. However, its effects on racially discordant oncology interactions are largely unknown. Thus, we examined whether oncologist implicit racial bias has similar effects in oncology interactions. We further investigated whether oncologist implicit bias negatively affects patients’ perceptions of recommended treatments (i.e., degree of confidence, expected difficulty). We predicted oncologist implicit bias would negatively affect communication, patient reactions to interactions, and, indirectly, patient perceptions of recommended treatments. Methods Participants were 18 non-black medical oncologists and 112 black patients. Oncologists completed an implicit racial bias measure several weeks before video-recorded treatment discussions with new patients. Observers rated oncologist communication and recorded interaction length of time and amount of time oncologists and patients spoke. Following interactions, patients answered questions about oncologists’ patient-centeredness and difficulty remembering contents of the interaction, distress, trust, and treatment perceptions. Results As predicted, oncologists higher in implicit racial bias had shorter interactions, and patients and observers rated these oncologists’ communication as less patient-centered and supportive. Higher implicit bias also was associated with more patient difficulty remembering contents of the interaction. In addition, oncologist implicit bias indirectly predicted less patient confidence in recommended treatments, and greater perceived difficulty completing them, through its impact on oncologists’ communication (as rated by both patients and observers). Conclusion Oncologist implicit racial bias is negatively associated with oncologist communication, patients’ reactions to racially discordant oncology interactions, and patient perceptions of recommended treatments. These perceptions could subsequently directly affect patient-treatment decisions. Thus, implicit racial bias is a likely source of racial treatment disparities and must be addressed in oncology training and practice. PMID:27325865

Purpose: To evaluate the ongoing structure of radiation oncology in Japan in terms of equipment, personnel, patient load, and geographic distribution to identify and improve any deficiencies. Methods and Materials: A questionnaire-based national structure survey was conducted from March to December 2008 by the Japanese Society of Therapeutic Radiology and Oncology (JASTRO). These data were analyzed in terms of the institutional stratification of the Patterns of Care Study. Results: The total numbers of new cancer patients and total cancer patients (new and repeat) treated with radiation in 2007 were estimated at 181,000 and 218,000, respectively. There were 807 linear accelerator,more » 15 telecobalt, 46 Gamma Knife, 45 {sup 60}Co remote-controlled after-loading, and 123 {sup 192}Ir remote-controlled after-loading systems in actual use. The linear accelerator systems used dual-energy function in 539 units (66.8%), three-dimensional conformal radiation therapy in 555 (68.8%), and intensity-modulated radiation therapy in 235 (29.1%). There were 477 JASTRO-certified radiation oncologists, 826.3 full-time equivalent (FTE) radiation oncologists, 68.4 FTE medical physicists, and 1,634 FTE radiation therapists. The number of interstitial radiotherapy (RT) administrations for prostate, stereotactic body radiotherapy, and intensity-modulated radiation therapy increased significantly. Patterns of Care Study stratification can clearly identify the maturity of structures based on their academic nature and caseload. Geographically, the more JASTRO-certified physicians there were in a given area, the more RT tended to be used for cancer patients. Conclusions: The Japanese structure has clearly improved during the past 17 years in terms of equipment and its use, although a shortage of personnel and variations in maturity disclosed by Patterns of Care Study stratification were still problematic in 2007.« less

The incidence of burnout or compassion fatigue in medical dosimetrists as a function of various stress and psychologic factors

DOE Office of Scientific and Technical Information (OSTI.GOV)

Howard, Michelle, E-mail: Mhoward24601@yahoo.com

ABSTRACT: Burnout and compassion fatigue (CF) adversely affect medical professionals, including those employed in radiation oncology. Previously conducted research acknowledged the presence of burnout in populations of radiation therapists, radiation oncologists, and oncology nursing staff. The aim of the following research was to measure the incidence of burnout or CF in the specific population of medical dosimetrists surveyed. As professional members of the radiation oncology team, this group had not been included in published research data to date. The hypothesis of the subsequent study stated that a comparable incidence of burnout would be observed among medical dosimetrists as had beenmore » reported by earlier researchers for a population of radiation therapists. A survey tool based on the Maslach Burnout Inventory (MBI) and distributed to full members of the American Association of Medical Dosimetrists (AAMD) was utilized as the research measurement method. Results obtained indicated an incidence rates of burnout or CF for medical dosimetrists were less than the rates previously measured for radiation therapists (53% vs 11% for emotional exhaustion [EE] and 45% vs 27% for depersonalization [DP]). The incidence of burnout was based on the Burnout Inventory (BI) developed for the research project. Each of the subscales, EE, DP, and decreased personal accomplishment (PA), was considered and analyzed independently. Although not as prevalent among medical dosimetrists as a variety of additional radiation oncology professionals, a significant portion of the population demonstrated signs of burnout or CF. Future concerns abound for the population of medical dosimetrists as a large number of members scored positive for intermediate risk of burnout and CF. Additionally, a large portion of the population was found to be rapidly approaching retirement.« less

2013-01-01

Purpose: In anticipation of oncologist workforce shortages projected as part of a 2007 study, the American Society of Clinical Oncology (ASCO) worked with a contractor to create a workforce information system (WIS) to assemble the latest available data on oncologist supply and cancer incidence and prevalence. ASCO plans to publish findings annually, reporting on new data and tracking trends over time. Methods: The WIS report is composed of three sections: supply, new entrants, and cancer incidence and prevalence. Tabulations of the number of oncologists in the United States are derived mainly from the American Medical Association Physician Masterfile. Information on fellows and residents in the oncology workforce pipeline come from published sources such as Journal of the American Medical Association. Incidence and prevalence estimates are published by the American Cancer Society and National Cancer Institute. Results: The WIS reports a total of 13,084 oncologists working in the United States in 2011. Oncologists are defined as those physicians who designate hematology, hematology/oncology, or medical oncology as their specialty. The WIS compares the characteristics of these oncologists with those of all physicians and tracks emerging trends in the physician training pipeline. Conclusion: Observing characteristics of the oncologist workforce over time allows ASCO to identify, prioritize, and evaluate its workforce initiatives. Accessible figures and reports generated by the WIS can be used by ASCO and others in the oncology community to advocate for needed health care system and policy changes to help offset future workforce shortages.

2015-01-01

Rapid development of sophisticated modalities has challenged radiation oncologists to evaluate workflow and care delivery processes. Our study assesses treatment modality use and willingness to alter management with anticipated limitations in reimbursement and resources. A web-based survey was sent to 43 radiation oncologists in a National Cancer Institute-designated comprehensive cancer center network. The survey contained 7 clinical cases with various acceptable treatment options based on our institutional clinical pathways. Each case was presented in 3 modules with varying situations: (1) unlimited resources with current reimbursement, (2) restricted reimbursement (bundled payment), and (3) both restricted reimbursement and resources. Reimbursement rates were based on the 2013 Medicare fee schedule. Adoption of lower reimbursing options (LROs) was defined as the percentage of scenarios in which a respondent selected an LRO compared with baseline. Forty-three physicians completed the survey, 11 (26%) at academic and 32 (74%) at community facilities. When bundled payment was imposed (module 1 vs 2), an increase in willingness to adopt LROs was observed (median 11.1%). When physicians were limited to both bundled payment and resource restriction, adoption of LROs was more pronounced (module 1 vs 3; median 22.2%, P < .01). There was a trend to selecting LROs between module 1 and 2 that reached significance when transitioning from module 1 to 3. A positive correlation between years in clinical practice and adoption of LROs was demonstrated (r(2) = 0.181, P<.01). This association remained significant when stratifying respondents by experience (≤25 vs >25 years, P = .02). Radiation oncologists were more likely to choose lower reimbursing treatment options when both resource restriction and bundled payment were presented. Those with fewer years of clinical practice were less inclined to alter management, perhaps reflecting modern residency training. Future cost-utility analyses may help to better guide radiation oncologists in selection of LROs. Copyright © 2015 American Society for Radiation Oncology. Published by Elsevier Inc.

2014-12-01

Purpose: To measure concordance among genitourinary radiation oncologists in using the National Cancer Institute Common Toxicity Criteria (NCI CTC) and Radiation Therapy Oncology Group (RTOG) grading scales to grade rectal bleeding. Methods and Materials: From June 2013 to January 2014, a Web-based survey was sent to 250 American and Canadian academic radiation oncologists who treat prostate cancer. Participants were provided 4 case vignettes in which patients received radiation therapy and developed rectal bleeding and were asked for management plans and to rate the bleeding according to NCI CTC v.4 and RTOG late toxicity grading (scales provided). In 2 cases, participantsmore » were also asked whether they would send the patient for colonoscopy. A multilevel, random intercept modeling approach was used to assess sources of variation (case, respondent) in toxicity grading to calculate the intraclass correlation coefficient (ICC). Agreement on a dichotomous grading scale (low grades 1-2 vs high grades 3-4) was also assessed, using the κ statistic for multiple respondents. Results: Seventy-two radiation oncologists (28%) completed the survey. Forty-seven (65%) reported having either written or been principal investigator on a study using these scales. Agreement between respondents was moderate (ICC 0.52, 95% confidence interval [CI] 0.47-0.58) when using NCI CTC and fair using the RTOG scale (ICC 0.28, 95% CI 0.20-0.40). Respondents who chose an invasive management were more likely to select a higher toxicity grade (P<.0001). Using the dichotomous scale, we observed moderate agreement (κ = 0.42, 95% CI 0.40-0.44) with the NCI CTC scale, but only slight agreement with the RTOG scale (κ = 0.19, 95% CI 0.17-0.21). Conclusion: Low interrater reliability was observed among radiation oncologists grading rectal bleeding using 2 common scales. Clearer definitions of late rectal bleeding toxicity should be constructed to reduce this variability and avoid ambiguity in both reporting and interpretation.« less

Abstract Background  Patients vary widely in their preferences and capacity for participation in medical decision‐making. This study aimed to document oncologist responses to more extreme presentations and identify helpful and unhelpful strategies for clinicians. Patients and methods  A trained actor played the role of a patient with early stage breast cancer who was attending her first consultation with a medical oncologist. She adopted in random order two different consultation participation styles: that of a very anxious, active patient, and that of a depressed, passive patient. Medical consultations between the actor and 16 medical oncologists were videotaped and then analysed qualitatively by two trained raters. Results  Strategies that facilitated shared decision‐making with both patient types and were positively endorsed by the actor/patient included explicit agenda‐setting, active listening, checking understanding, endorsing question‐asking, offering decisional delay, and non‐verbal behaviours conveying empathy and warmth. Oncologists successfully negotiated with the active patient to share control of the consultation, and responded to emotional cues from the passive patient. Unhelpful strategies were also identified. Conclusions  Few clinicians receive training in responding to differing communication styles in their patients that could potentially cause conflict and hinder optimal treatment decision‐making. This study suggests some useful strategies for oncologists to consider, to widen their behavioural repertoire in the cancer consultation. PMID:12199662

Multiple clinical trials have demonstrated that intravesical Bacillus Calmette-Guérin (BCG) treatment reduces recurrences and progression in patients with non-muscle-invasive bladder cancer (NMIBC). However, although BCG has been in use for almost 40 years, this agent is often underutilized and practice patterns of administration vary. This neglect is most likely caused by uncertainties about the optimal use of BCG, including unawareness of optimal treatment schedules and about patient populations that most benefit from BCG treatment. To address this deficit, a focus group of specialized urologic oncologists (urologists, medical oncologists and radiation oncologists) reviewed the current guidelines and clinical evidence, discussed their experiences and formed a consensus regarding the optimal use of BCG in the management of patients with NIMBC. The experts concluded that continuing therapy with 3-week BCG maintenance is superior to induction treatment only and is the single most important factor in improving outcomes in patients with NMIBC. They also concluded that a reliable alternative to radical cystectomy in truly BCG-refractory disease remains the subject of clinical trials. In addition, definitions for common terms of BCG failure, such as BCG-refractory and BCG-intolerant, have been formulated.

Current Standard and Investigational Approaches to the Management of Hormone-Refractory Prostate Cancer

Prostate cancer is a common cause of death in men and remains incurable in the metastatic setting. In 2004, 2 landmark trials using docetaxel-based chemotherapy, TAX 327 and SWOG 99-16, showed a survival benefit for the first time in metastatic, hormone-refractory prostate cancer. Current research suggests that several distinct mechanisms of androgen-refractory disease may converge in patients with disease progression on androgen deprivation therapy. These findings have identified several potential targets for therapeutic intervention. Current standard and investigational treatment options for this disease are discussed, including chemotherapy and rapidly evolving therapies in phase II/III trials involving antiangiogenic therapies, signal transduction inhibitors, immunomodulatory agents, and nuclear receptor targets. In light of a growing array of treatment options and an increasingly chronic natural history, this review supports a multidisciplinary care approach to these patients, including medical oncologists, urologists, and radiation oncologists, to optimize survival and quality of life.

Providing patients with unrestricted access to their electronic medical records through patient portals has impacted patient-provider communication and patients' personal health knowledge. However, little is known about how patient portals are used in oncology. The aim of this study was to understand attitudes of the portal's adoption for oncology and to identify the advantages and disadvantages of using the portal to communicate and view medical information. In-depth semistructured interviews were conducted with 60 participants: 35 patients, 13 oncologists, and 12 medical informaticists. Interviews were recorded, transcribed, and thematically analyzed to identify critical incidents and general attitudes encountered by participants. Two primary themes were discovered: (1) implementation practices influence attitudes, in which the decision-making and execution process of introducing portals throughout the hospital did not include the input of oncologists. Lack of oncologists' involvement led to a lack of knowledge about portal functionality, such as not knowing the time period when test results would be disclosed to patients; (2) perceptions of portals as communication tools varies by user type, meaning that each participant group (patients, oncologists, and medical informaticists) had varied opinions about how the portal should be used to transmit and receive information. Oncologists and medical informaticists had difficulty understanding one another's culture and communication processes in their fields, while patients had preferences for how they would like to receive communication, but it largely depended upon the type of test being disclosed. The majority of patients (54%, 19/35) who participated in this study viewed lab results or scan reports via the portal before being contacted by a clinician. Most were relatively comfortable with this manner of disclosure but still preferred face-to-face or telephone communication. Findings from this study indicate that portal education is needed for both patients and oncologists, especially when portals are implemented across entire health systems since highly specialized areas of medicine may have unique needs and uses. Patient portals in oncology can potentially alter the way diagnoses are delivered and how patients and oncologists communicate. Therefore, communication about the portal should be established during initial consultations so patients can decide whether they want to be informed in such a manner. ©Jordan M Alpert, Bonny B Morris, Maria D Thomson, Khalid Matin, Richard F Brown.

Oncologists in the United States and Canada work in different health care systems, but physicians in both countries face challenges posed by the rising costs of cancer drugs. We compared their attitudes regarding the costs and cost-effectiveness of medications and related health policy. Survey responses of a random sample of 1,355 United States and 238 Canadian medical oncologists (all outside of Québec) were compared. Response rate was 59%. More US oncologists (67% v 52%; P < .001) favor access to effective treatments regardless of cost, while more Canadians favor access to effective treatments only if they are cost-effective (75% v 58%; P < .001). Most (84% US, 80% Canadian) oncologists state that patient out-of-pocket costs influence their treatment recommendations, but less than half the respondents always or frequently discuss the costs of treatments with their patients. The majority of oncologists favor more use of cost-effectiveness data in coverage decisions (80% US, 69% Canadian; P = .004), but fewer than half the oncologists in both countries feel well equipped to use cost-effectiveness information. Majorities of oncologists favor government price controls (57% US, 68% Canadian; P = .01), but less than half favor more cost-sharing by patients (29% US, 41% Canadian; P = .004). Oncologists in both countries prefer to have physicians and nonprofit agencies determine whether drugs provide good value. Oncologists in the United States and Canada generally have similar attitudes regarding cancer drug costs, cost-effectiveness, and associated policies, despite practicing in different health care systems. The results support providing education to help oncologists in both countries use cost-effectiveness information and discuss drug costs with their patients.

Little is known about the association between patient-oncologist discussion of cancer treatment out-of-pocket (OOP) cost and medication adherence, a critical component of quality cancer care. We surveyed insured adults receiving anticancer therapy. Patients were asked if they had discussed OOP cost with their oncologist. Medication nonadherence was defined as skipping doses or taking less medication than prescribed to make prescriptions last longer, or not filling prescriptions because of cost. Multivariable analysis assessed the association between nonadherence and cost discussions. Among 300 respondents (86% response), 16% (n = 49) reported high or overwhelming financial distress. Nineteen percent (n = 56) reported talking to their oncologist about cost. Twenty-seven percent (n = 77) reported medication nonadherence. To make a prescription last longer, 14% (n = 42) skipped medication doses, and 11% (n = 33) took less medication than prescribed; 22% (n = 66) did not fill a prescription because of cost. Five percent (n = 14) reported chemotherapy nonadherence. To make a prescription last longer, 1% (n = 3) skipped chemotherapy doses, and 2% (n = 5) took less chemotherapy; 3% (n = 10) did not fill a chemotherapy prescription because of cost. In adjusted analyses, cost discussion (odds ratio [OR] = 2.58; 95% CI, 1.14 to 5.85; P = .02), financial distress (OR = 1.64, 95% CI, 1.38 to 1.96; P < .001) and higher financial burden than expected (OR = 2.89; 95% CI, 1.41 to 5.89; P < .01) were associated with increased odds of nonadherence. Patient-oncologist cost communication and financial distress were associated with medication nonadherence, suggesting that cost discussions are important for patients forced to make cost-related behavior alterations. Future research should examine the timing, content, and quality of cost-discussions. Copyright © 2014 by American Society of Clinical Oncology.

Automated consensus contour building for prostate MRI.

PubMed

Khalvati, Farzad

2014-01-01

Inter-observer variability is the lack of agreement among clinicians in contouring a given organ or tumour in a medical image. The variability in medical image contouring is a source of uncertainty in radiation treatment planning. Consensus contour of a given case, which was proposed to reduce the variability, is generated by combining the manually generated contours of several clinicians. However, having access to several clinicians (e.g., radiation oncologists) to generate a consensus contour for one patient is costly. This paper presents an algorithm that automatically generates a consensus contour for a given case using the atlases of different clinicians. The algorithm was applied to prostate MR images of 15 patients manually contoured by 5 clinicians. The automatic consensus contours were compared to manual consensus contours where a median Dice similarity coefficient (DSC) of 88% was achieved.

To analyze up-to-date Hirsch index ( h -index) data to estimate the scholarly productivity of academic radiation oncology faculty. Bibliometric citation database searches were performed for radiation oncology faculty at domestic residency-training institutions. Outcomes analyzed included the number of manuscripts, number of citations, and h -index between 1996 and 2012. Analyses of overall h -index rankings with stratification by academic ranking, gender, and departmental faculty size were performed. One thousand thirty-seven radiation oncologists from 87 programs were included. Overall, the mean h -index was 10.8. Among the top 10% by h -index, 38% were chairpersons, all were senior faculty, and 11% were women. As expected, higher h -index was associated with higher academic ranking and senior faculty status. Recursive partitioning analysis revealed an h -index threshold of 20 ( p <0.001) as an identified breakpoint between senior vs. junior faculty. Furthermore, h -index breakpoints of 12 ( p <0.001) and 25 ( p <0.001) were identified between assistant professor vs. associate professor, and associate professor vs. professor levels, respectively. Multivariate analysis identified higher academic ranking, male gender, and larger departmental faculty size as independent variables associated with higher h -index. The current results suggest an overall rise in scholarly citation metrics among domestic academic radiation oncologists, with a current mean h- index of 10.8, vs. 8.5 in 2008. Significant relationships exist between h -index and academic rank, gender, and departmental size. The results offer up-to-date benchmarks for evaluating academic radiation oncologist to the national average and potentially has utility in the process of appointment and promotion decisions.

Purpose: The purpose of this study was to determine trends in radiation oncology malpractice claims and expenses during the last 28 years and to compare radiation oncology malpractice claims to those of other specialties. Methods and Materials: We performed a retrospective analysis of closed malpractice claims filed from 1985 to 2012, collected by a nationwide medical liability insurance trade association. We analyzed characteristics and trends among closed claims, indemnity payments (payments to plaintiff), and litigation expenses. We also compared radiation oncology malpractice claims to those of 21 other medical specialties. Time series dollar amounts were adjusted for inflation (2012 was themore » index year). Results: There were 1517 closed claims involving radiation oncology, of which 342 (22.5%) were paid. Average and median indemnity payments were $276,792 and $122,500, respectively, ranking fifth and eighth, respectively, among the 22 specialty groups. Linear regression modeling of time trends showed decreasing total numbers of claims (β = −1.96 annually, P=.003), increasing average litigation expenses paid (β = +$1472 annually, P≤.001), and no significant changes in average indemnity payments (β = −$681, P=.89). Conclusions: Medical professional liability claims filed against radiation oncologists are not common and have declined in recent years. However, indemnity payments in radiation oncology are large relative to those of many other specialties. In recent years, the average indemnity payment has been stable, whereas litigation expenses have increased.« less

The cost of cancer care continues to increase at an unprecedented rate. Concerns have been raised about financial incentives associated with the chemotherapy concession in oncology practices and their impact on treatment recommendations. The objective of this study was to measure the physician-reported effects of prescribing chemotherapy or growth factors or making referrals to other cancer specialists, hospice, or hospital admissions on medical oncologists' income. US medical oncologists involved in the care of a population-based cohort of patients with lung or colorectal cancer from the Cancer Care Outcomes Research and Surveillance (CanCORS) study were surveyed regarding their perceptions of the impact of prescribing practices or referrals on their income. Although most oncologists reported that their incomes would be unaffected, compared with salaried oncologists, physicians in fee-for-service practice, and those paid a salary with productivity incentives were more likely to report that their income would increase from administering chemotherapy (odds ratios [ORs], 7.05 and 7.52, respectively; both P < .001) or administering growth factors (ORs, 5.60 and 6.03, respectively; both P < .001). A substantial proportion of oncologists who are not paid a fixed salary report that their incomes increase when they administer chemotherapy and growth factors. Further research is needed to understand the impact of these financial incentives on both the quality and cost of care.

One of the priorities of personalized medicine regards the role of early integration of palliative care with cancer-directed treatments, called simultaneous care. This article, written by the Italian Association of Medical Oncology (AIOM) Simultaneous and Continuous Care Task Force, represents the position of Italian medical oncologists about simultaneous care, and is the result of a 2-step project: a Web-based survey among medical oncologists and a consensus conference. We present the opinion of more than 600 oncologists who helped formulate these recommendations. This document covers 4 main aspects of simultaneous care: 1) ethical, cultural, and relational aspects of cancer and implications for patient communication; 2) training of medical oncologists in palliative medicine; 3) research on the integration between cancer treatments and palliative care; and 4) organizational and management models for the realization of simultaneous care. The resulting recommendations highlight the role of skills and competence in palliative care along with implementation of adequate organizational models to accomplish simultaneous care, which is considered a high priority of AIOM in order to grant the best quality of life for cancer patients and their families.

Basics of particle therapy I: physics

With the advance of modern radiation therapy technique, radiation dose conformation and dose distribution have improved dramatically. However, the progress does not completely fulfill the goal of cancer treatment such as improved local control or survival. The discordances with the clinical results are from the biophysical nature of photon, which is the main source of radiation therapy in current field, with the lower linear energy transfer to the target. As part of a natural progression, there recently has been a resurgence of interest in particle therapy, specifically using heavy charged particles, because these kinds of radiations serve theoretical advantages in both biological and physical aspects. The Korean government is to set up a heavy charged particle facility in Korea Institute of Radiological & Medical Sciences. This review introduces some of the elementary physics of the various particles for the sake of Korean radiation oncologists' interest. PMID:22984664

Music therapy is a common complementary and alternative therapy in addition to medical treatment for patients with cancer. If music therapy, which is known has a positive effect on human emotions and behaviors, is a useful additional therapy, it should be more integrated into pyscho-oncology. In this study, we aimed to determine medical oncologist attitudes to music therapy for patients with cancer and knowledge about musicology and music therapy in Turkey. This survey study included questions about participant attitudes and knowledge regarding music therapy as well as demographic characteristics. The population of the study were 402 physicians working in medical oncology in Turkey and the sample covered 112 participants in the the survey. For statistical analyses the chi-square test, Fischer exact test, and Mann-Whitney U analysis are applied. In our study the rate for medical oncologists who were interested in music therapy was 28% (n=112). Some 30% (n=34) of medical oncologists recommended music therapy for their patients and 55% (n=61) recommended music therapy to prevent anxiety in patients with cancer. In this study, for more harmony with patients and in order to ensure management of adverse effect, it was concluded that music therapy should be regrded as an additional therapy in oncology clinics.

Oncology health professionals (HPs) are increasingly required to care for patients from minority backgrounds. Yet many HPs have not had formal training in how to communicate effectively in culturally diverse settings. More information is needed about the challenges that oncology HPs face in communicating with minority patients to inform the content of formal training programs. This qualitative study aimed to identify oncology nurses' and oncologists' individual experiences and challenges in communicating with patients from minority backgrounds. Thirty-eight oncology HPs (21 oncology nurses, 12 medical oncologists, and 5 radiation oncologists) were interviewed individually or in focus groups about their experiences communicating with patients from minority backgrounds. The interviews were audio taped and analysed thematically. The majority of participants (82%) reported varying degrees of uncertainty and discomfort regarding working with minority patients, with many barriers to communication encountered. Participants perceived that minority patients received less emotional support than majority group patients. They experienced challenges in balancing beliefs about patient autonomy with cultural differences regarding the role of the family. Strategies employed by participants to facilitate interactions included: modifying speech, taking more time in consultations, rapport building, and using nonverbal techniques. Oncology HPs encounter many linguistic and cultural barriers when communicating with minority patients. They need formal training tailored to developing culturally competent communication. Oncology nurses and oncologists could benefit from formal communication skills training focused upon cultural competence during their career development programs. Copyright © 2016 Elsevier Ltd.

Clinical scenarios associated with low therapeutic effectiveness (LTE) are especially complex and highly relevant in oncology. The objective was to test a methodological framework for creating consensual clinical recommendations for routine practice. The study was in three phases from Mars 2006 to January 2008: 1) Definition of LTE situations; 2) Preparation by 10 experts of a panel of LTE situations in cancers of breast, lung, head and neck, colon and rectum and brain; and 3) Development of a consensus on each situation and its optimal treatment by gathering agreement and disagreements (two-round Delphi method) from 68 practicing oncologists in Andalusian Community. Three major and three minor criteria were established for an LTE situation, defined when at least one major or two minor criteria were met. The expert group proposed 48 possible LTE clinical scenarios for breast (n = 7), lung (10), brain (11), head and neck (11) and colorectal cancers (9). Sixty-eight oncologists agreed to participate in the study; the response rate was 79% (from 34 medical and 17 radiation oncologists) In the first round (definition), maximum agreement was obtained with the LTE definition of 10 of the 48 scenarios; in the second round (treatment options), maximum agreement was obtained on the treatment of 3 of these 10 scenarios. Oncologists reached low levels of agreement on the definition of an LTE situation and on its treatment recommendations. This study proposes an approach to the improvement of cancer management in situations of high uncertainty.

To evaluate satisfaction with work-life balance (WLB) and career plans of US oncologists. The American Society of Clinical Oncology conducted a survey of US oncologists evaluating satisfaction with WLB and career plans between October 2012 and March 2013. The sample included equal numbers of men and women from all career stages. Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys. From 1,117 oncologists (37.3% of overall sample) completing full-length surveys, we evaluated satisfaction with WLB and career plans among the 1,058 who were not yet retired. The proportion of oncologists satisfied with WLB (n = 345; 33.4%) ranked lower than that reported for all other medical specialties in a recent national study. Regarding career plans, 270 oncologists (26.5%) reported a moderate or higher likelihood of reducing their clinical work hours in the next 12 months, 351 (34.3%) indicated a moderate or higher likelihood of leaving their current position within 24 months, and 273 (28.5%) planned to retire before 65 years of age. Multivariable analyses found women oncologists (odds ratio [OR], 0.458; P < .001) and those who devoted greater time to patient care (OR for each additional hour, 0.977; P < .001) were less likely to be satisfied with WLB. Satisfaction with WLB and burnout were the strongest predictors of intent to reduce clinical work hours and leave current position on multivariable analysis. Satisfaction with WLB among US oncologists seems lower than for other medical specialties. Dissatisfaction with WLB shows a strong relationship with plans to reduce hours and leave current practice. Given the pending US oncologist shortage, additional studies exploring interactions among WLB, burnout, and career satisfaction and their impact on career and retirement plans are warranted.

This descriptive cross-sectional survey aims to assess the level of concordance between the perspectives of oncologists and those of patients regarding oral mucositis (OM) symptoms, and the impact of OM on various aspects of daily living and concurrent cancer management. Oncologists involved in OM management (n = 105), and patients who developed OM during cancer treatment (n = 175), were recruited from seven Asian countries. Oncologists completed a face-to-face, quantitative interview; patients completed a face-to-face interview, and a self-reported questionnaire. Oncologists and patients ranked treatment-induced OM among the three most important toxicities of cancer therapy requiring intervention. The most frequent OM symptoms reported by patients were oral ulcers (74%), dry mouth (73%), and difficulty swallowing (62%). Oncologists expected mild OM symptoms to last slightly longer than 1 week, whereas patients reported mild symptoms for more than 2 weeks. In mild-to-moderate OM, oncologists underestimated patients' pain experience. Overall, only 45% of oncologists said they would initiate OM prophylaxis when cancer therapy started. Of the 87% of patients who said they used their prescribed medications, only 16% reported using prophylactically prescribed medication. While oncologists' concerns related to the delays and interruptions of cancer treatment, patients tended to focus on the effects of OM on eating, drinking, and talking. Oncologists' and patients' perceptions about treatment-induced OM differ. To overcome discordant perspectives, there is a need to raise general awareness and improve proactive management of OM. As noted in recent guidelines, supportive cancer care is critical for ensuring optimal therapy and for improving the patient's experience.

To summarize important talking points from a 2016 symposium focusing on real-world challenges to advancing precision medicine in radiation oncology, and to help radiation oncologists navigate the practical challenges of precision, radiation oncology. The American Society for Radiation Oncology, American Association of Physicists in Medicine, and National Cancer Institute cosponsored a meeting on precision medicine in radiation oncology. In June 2016 numerous scientists, clinicians, and physicists convened at the National Institutes of Health to discuss challenges and future directions toward personalized radiation therapy. Various breakout sessions were held to discuss particular components and approaches to the implementation of personalized radiation oncology. This article summarizes the genomically guided radiation therapy breakout session. A summary of existing genomic data enabling personalized radiation therapy, ongoing clinical trials, current challenges, and future directions was collected. The group attempted to provide both a current overview of data that radiation oncologists could use to personalize therapy, along with data that are anticipated in the coming years. It seems apparent from the provided review that a considerable opportunity exists to truly bring genomically guided radiation therapy into clinical reality. Genomically guided radiation therapy is a necessity that must be embraced in the coming years. Incorporating these data into treatment recommendations will provide radiation oncologists with a substantial opportunity to improve outcomes for numerous cancer patients. More research focused on this topic is needed to bring genomic signatures into routine standard of care. Published by Elsevier Inc.

The number of cancer patients in Europe is rising and significant advances in basic and applied cancer research are making the provision of optimal care more challenging. The concept of cancer as a systemic, highly heterogeneous and complex disease has increased the awareness that quality cancer care should be provided by a multidisciplinary team (MDT) of highly qualified healthcare professionals. Cancer patients also have the right to benefit from medical progress by receiving optimal treatment from adequately trained and highly skilled medical professionals. Built on the highest standards of professional training and continuing medical education, medical oncology is recognised as an independent medical specialty in many European countries. Medical oncology is a core member of the MDT and offers cancer patients a comprehensive and systemic approach to treatment and care, while ensuring evidence-based, safe and cost-effective use of cancer drugs and preserving the quality of life of cancer patients through the entire 'cancer journey'. Medical oncologists are also engaged in clinical and translational research to promote innovation and new therapies and they contribute to cancer diagnosis, prevention and research, making a difference for patients in a dynamic, stimulating professional environment. Medical oncologists play an important role in shaping the future of healthcare through innovation and are also actively involved at the political level to ensure a maximum contribution of the profession to Society and to tackle future challenges. This position paper summarises the multifarious and vital contributions of medical oncology and medical oncologists to today's and tomorrow's professional cancer care.

An increasing attention is being paid to disclosures of conflicts of interests in the field of oncology. The purpose of this study was to examine how radiation oncologists report their conflicts of interests with pharmaceutical or technology industries. We collected the data of conflicts of interests disclosures in the abstract books from the annual 2012 and 2013 meetings of the American Society for Radiation Oncology (ASTRO) in Miami (FL, USA), and in Atlanta (GA, USA), respectively. Geographic origins of abstracts as well other factors were examined. We identified a total of 4219 abstracts published in the past two years. The total number of involved authors was of 28,283. All of the published abstracts had conflicts of interests disclosures. Amongst them, 563 abstracts (13.4%) reported at least one potential conflict of interests, in which 1264 (4.5%) declared a potential conflict of interests in their disclosures. Geographic distribution of abstracts with financial relationship was as following: 67.9%, 15.5%, 7.7% and 7.7% for USA, Europe, Asia/Pacifica, and Canada, respectively. Abstracts with conflict of interest originated from North America in 75.6% of cases. USA distribution was 70.6% and 29.4% for Eastern and Western, respectively. The proportion of physicians declaring financial conflicts of interests remains extremely low, whichever geographic area authors are from. In comparison to the rest of the world, the US proved itself better at declaring potential links. Changes in medical culture and education could represent a significant step to improve the process of revealing conflicts of interest in medical journal as well as in international meetings.

The extent to which medical oncologists consider non-clinical patient factors when deciding to recommend adjuvant chemotherapy is unknown. Medical oncologists who treated a population-based sample of early stage breast cancer patients reported to the Los Angeles and Detroit Surveillance, Epidemiology, and End Results registries 2005-2007 were asked how strongly they consider a patient's ability to follow instructions, level of social support, and level of work support/flexibility in decisions to recommend adjuvant chemotherapy. Responses of 4 (Quite strongly) or 5 (Very strongly) on a five-point Likert scale defined strong consideration. Associations between oncologist/practice characteristics and strong consideration of each non-clinical factor were examined. 134 oncologists (66 %) reported strong consideration of one or more factor. Ability to follow instructions was strongly considered by 120 oncologists (59 %), social support by 78 (38 %), and work support/flexibility by 73 (36 %). Larger percent of practice devoted to breast cancer was associated with lower likelihood of strongly considering ability to follow instructions [odds ratio (OR) 0.98, 95 % confidence interval (CI) 0.97-0.99; P = 0.04]. Increased years in practice was associated with lower likelihood of strongly considering social support (OR 0.96, CI 0.93-0.99; P = 0.011), while non-white race (OR 2.1, CI 1.03-4.26; P = 0.041) and tumor board access (OR 2.04, CI 1.01-4.12; P = 0.048) were associated with higher likelihood. Non-white race was associated with strongly considering work support/flexibility (OR 2.44, CI 1.21-4.92; P = 0.013). Tumor board access (OR 2, CI 1.00-4.02; P = 0.051) was borderline significant. Non-clinical patient factors play a role in medical oncologist decision-making for breast cancer adjuvant chemotherapy recommendations.

Purpose: To develop multi-institutional consensus clinical target volumes (CTVs) and organs at risk (OARs) for male and female bladder cancer patients undergoing adjuvant radiation therapy (RT) in clinical trials. Methods and Materials: We convened a multidisciplinary group of bladder cancer specialists from 15 centers and 5 countries. Six radiation oncologists and 7 urologists participated in the development of the initial contours. The group proposed initial language for the CTVs and OARs, and each radiation oncologist contoured them on computed tomography scans of a male and female cystectomy patient with input from ≥1 urologist. On the basis of the initial contouring, themore » group updated its CTV and OAR descriptions. The cystectomy bed, the area of greatest controversy, was contoured by another 6 radiation oncologists, and the cystectomy bed contouring language was again updated. To determine whether the revised language produced consistent contours, CTVs and OARs were redrawn by 6 additional radiation oncologists. We evaluated their contours for level of agreement using the Landis-Koch interpretation of the κ statistic. Results: The group proposed that patients at elevated risk for local-regional failure with negative margins should be treated to the pelvic nodes alone (internal/external iliac, distal common iliac, obturator, and presacral), whereas patients with positive margins should be treated to the pelvic nodes and cystectomy bed. Proposed OARs included the rectum, bowel space, bone marrow, and urinary diversion. Consensus language describing the CTVs and OARs was developed and externally validated. The revised instructions were found to produce consistent contours. Conclusions: Consensus descriptions of CTVs and OARs were successfully developed and can be used in clinical trials of adjuvant radiation therapy for bladder cancer.« less

We have proposed a computer-assisted framework for machine-learning-based delineation of gross tumor volumes (GTVs) following an optimum contour selection (OCS) method. The key idea of the proposed framework was to feed image features around GTV contours (determined based on the knowledge of radiation oncologists) into a machine-learning classifier during the training step, after which the classifier produces the 'degree of GTV' for each voxel in the testing step. Initial GTV regions were extracted using a support vector machine (SVM) that learned the image features inside and outside each tumor region (determined by radiation oncologists). The leave-one-out-by-patient test was employed for training and testing the steps of the proposed framework. The final GTV regions were determined using the OCS method that can be used to select a global optimum object contour based on multiple active delineations with a LSM around the GTV. The efficacy of the proposed framework was evaluated in 14 lung cancer cases [solid: 6, ground-glass opacity (GGO): 4, mixed GGO: 4] using the 3D Dice similarity coefficient (DSC), which denotes the degree of region similarity between the GTVs contoured by radiation oncologists and those determined using the proposed framework. The proposed framework achieved an average DSC of 0.777 for 14 cases, whereas the OCS-based framework produced an average DSC of 0.507. The average DSCs for GGO and mixed GGO were 0.763 and 0.701, respectively, obtained by the proposed framework. The proposed framework can be employed as a tool to assist radiation oncologists in delineating various GTV regions. © The Author 2016.

Shakespeare, Thomas P

2015-11-18

Positron emission tomography (PET) imaging is routinely used in many cancer types, although is not yet a standard modality for prostate carcinoma. Prostate-specific membrane antigen (PSMA) PET is a promising new modality for staging prostate cancer, with recent studies showing potential advantages over traditional computed tomography (CT), magnetic resonance imaging (MRI) and nuclear medicine bone scan imaging. However, the impact of PSMA PET on the decision-making of radiation oncologists and outcomes after radiotherapy is yet to be determined. Our aim was to determine the impact of PSMA PET on a radiation oncologist's clinical practice. Patients in a radiation oncology clinic who underwent PSMA PET were prospectively recorded in an electronic oncology record. Patient demographics, outcomes of imaging, and impact on decision-making were evaluated. Fifty-four patients underwent PSMA PET between January and May 2015. The major reasons for undergoing PET included staging before definitive (14.8%) or post-prostatectomy (33.3%) radiotherapy, and investigation of PSA failures following definitive (16.7%) or post-prostatectomy (33.3%) radiotherapy. In 46.3% of patients PSMA was positive after negative traditional imaging, in 9.3% PSMA was positive after equivocal imaging, and in 13.0% PSMA was negative after equivocal imaging. PSMA PET changed radiotherapy management in 46.3% of cases, and hormone therapy in 33.3% of patients, with an overall change in decision-making in 53.7% of patients. PSMA PET has the potential to significantly alter the decision-making of radiation oncologists, and may become a valuable imaging tool in the future.

Purpose: Despite the extensive use of complementary and alternative medicine (CAM) among cancer patients, patient-physician communication regarding CAM therapies remains limited. This study quantified the extent of patient-physician communication about CAM and identified factors associated with its discussion in radiation therapy (RT) settings. Methods and Materials: We conducted a cross-sectional survey of 305 RT patients at an urban academic cancer center. Patients with different cancer types were recruited in their last week of RT. Participants self-reported their demographic characteristics, health status, CAM use, patient-physician communication regarding CAM, and rationale for/against discussing CAM therapies with physicians. Multivariate logistic regression was usedmore » to identify relationships between demographic/clinical variables and patients' discussion of CAM with radiation oncologists. Results: Among the 305 participants, 133 (43.6%) reported using CAM, and only 37 (12.1%) reported discussing CAM therapies with their radiation oncologists. In multivariate analyses, female patients (adjusted odds ratio [AOR] 0.45, 95% confidence interval [CI] 0.21-0.98) and patients with full-time employment (AOR 0.32, 95% CI 0.12-0.81) were less likely to discuss CAM with their radiation oncologists. CAM users (AOR 4.28, 95% CI 1.93-9.53) were more likely to discuss CAM with their radiation oncologists than were non-CAM users. Conclusions: Despite the common use of CAM among oncology patients, discussions regarding these treatments occur rarely in the RT setting, particularly among female and full-time employed patients. Clinicians and patients should incorporate discussions of CAM to guide its appropriate use and to maximize possible benefit while minimizing potential harm.« less

The purposes of this exploratory study were to investigate the attitudes of radiation oncology professionals regarding interprofessional (IP) teaching and interprofessional education (IPE), to identify the challenges faced by radiation oncologists who teach within an IP context, and to discover new strategies to aid professionals teaching IP students. A questionnaire was developed through the review of existing literature on IPE using Medline. The proposed group of questions was selected by educators from different professions actively involved in IPE. The final revised questionnaire consisted of three main domains assessing the understanding of IP concepts, attitudes toward IP teaching and learning environments, and attitudes toward health-care teams. An open-ended comment section was included. The questionnaire was administered to health-care professionals (physicists, radiation oncologists, and radiation therapists) nationally through SurveyMonkey® (electronic survey). A total of 220 respondents provided demographic information. Half of these respondents indicated that they previously received education relating to IPE. A high level of agreement was received for nearly all the questions. There were no significant statistical differences among the three different professional respondent groups for any question. Overall, most of the respondents demonstrated a good knowledge and understanding of IP concepts and advocated IP training and collaboration.

Collaboration between specialists is essential for achieving high-value care in patients with complex cancer needs. We explore how collaboration between oncologists and surgeons affects mortality and cost for patients requiring multispecialty cancer care. This was a retrospective cohort study of patients with stage III colon cancer from SEER-Medicare diagnosed between 2000 and 2009. Patients were assigned to a primary treating surgeon and oncologist. Collaboration between surgeon and oncologist was measured as the number of patients shared between them; this has been shown to reflect advice seeking and referral relationships between physicians. Outcomes included hazards for all-cause mortality, subhazards for colon cancer-specific mortality, and cost of care at 12 months. A total of 9,329 patients received care from 3,623 different surgeons and 2,319 medical oncologists, representing 6,827 unique surgeon-medical oncologist pairs. As the number of patients shared between specialists increased from to one to five (25th to 75th percentile), patients experienced an approximately 20% improved survival benefit from all-cause and colon cancer-specific mortalities. Specifically, for each additional patient shared between oncologist and surgeon, all-cause mortality improved by 5% (hazard ratio, 0.95; 95%CI, 0.92 to 0.97), and colon cancer-specific mortality improved by 5% (subhazard ratio, 0.95; 95% CI, 0.91 to 0.97). There was no association with cost. Specialist collaboration is associated with lower mortality without increased cost among patients with stage III colon cancer. Facilitating formal and informal collaboration between specialists may be an important strategy for improving the care of patients with complex cancers.

The consultation fee for outpatient radiotherapy was newly introduced in the national health insurance system in Japan in April 2012. We conducted a survey on the use of this consultation fee and its effect on clinical practices. The health insurance committee of the Japanese Society of Therapeutic Radiology and Oncology conducted a questionnaire survey. The questionnaire form was mailed to 160 councilors of the Society, the target questionees. A total of 94 answers (58% of the target questionees) sent back were used for analyses. The analyses revealed that 75% of the hospitals charged most of the patients who receive radiotherapy in an outpatient setting a consultation fee. The introduction of the consultation fee led to some changes in radiation oncology clinics, as evidenced by the response of 'more careful observations by medical staff' in 37% of questionees and a 12% increase in the number of full-time radiation oncology nurses. It was also shown that the vast majority (92%) of radiation oncologists expected a positive influence of the consultation fee on radiation oncology clinics in Japan. Our questionnaire survey revealed the present status of the use of a newly introduced consultation fee for outpatient radiotherapy, and the results suggested its possible effect on promoting a multidisciplinary medical care system in radiation oncology departments in Japan.

Implications of Patient Portal Transparency in Oncology: Qualitative Interview Study on the Experiences of Patients, Oncologists, and Medical Informaticists

PubMed Central

2018-01-01

Background Providing patients with unrestricted access to their electronic medical records through patient portals has impacted patient-provider communication and patients’ personal health knowledge. However, little is known about how patient portals are used in oncology. Objective The aim of this study was to understand attitudes of the portal’s adoption for oncology and to identify the advantages and disadvantages of using the portal to communicate and view medical information. Methods In-depth semistructured interviews were conducted with 60 participants: 35 patients, 13 oncologists, and 12 medical informaticists. Interviews were recorded, transcribed, and thematically analyzed to identify critical incidents and general attitudes encountered by participants. Results Two primary themes were discovered: (1) implementation practices influence attitudes, in which the decision-making and execution process of introducing portals throughout the hospital did not include the input of oncologists. Lack of oncologists’ involvement led to a lack of knowledge about portal functionality, such as not knowing the time period when test results would be disclosed to patients; (2) perceptions of portals as communication tools varies by user type, meaning that each participant group (patients, oncologists, and medical informaticists) had varied opinions about how the portal should be used to transmit and receive information. Oncologists and medical informaticists had difficulty understanding one another’s culture and communication processes in their fields, while patients had preferences for how they would like to receive communication, but it largely depended upon the type of test being disclosed. Conclusions The majority of patients (54%, 19/35) who participated in this study viewed lab results or scan reports via the portal before being contacted by a clinician. Most were relatively comfortable with this manner of disclosure but still preferred face-to-face or telephone communication. Findings from this study indicate that portal education is needed for both patients and oncologists, especially when portals are implemented across entire health systems since highly specialized areas of medicine may have unique needs and uses. Patient portals in oncology can potentially alter the way diagnoses are delivered and how patients and oncologists communicate. Therefore, communication about the portal should be established during initial consultations so patients can decide whether they want to be informed in such a manner. PMID:29581090

The purpose of this investigation was to explicate the content of primary adjuvant treatment consultations in breast oncology and examine the predictive relationships between patient and oncologist consultation factors and patient satisfaction with communication. The recorded consultations of 172 newly diagnosed breast cancer patients from four Canadian cancer centers were randomly drawn from a larger subset of 481 recordings and examined by three coders using the Medical Interaction Process System (MIPS); a system that categorizes the content and mode of each distinct utterance. The MIPS findings, independent observer ratings of patient and oncologist affective behavior, and derived consultation ratios of patient centeredness, patient directedness, and psychosocial focus, were used to predict patient satisfaction with communication post-consultation and at 12-weeks post-consultation. Biomedical content categories were predominant in the consultations, accounting for 88% of all utterances, followed by administrative (6%) and psychosocial (6%) utterances. Post-consultation satisfaction with communication was significantly higher for older patients, those with smaller primary tumors and those with longer consultations. Smaller tumor, lack of patient assertiveness during the treatment consultation and having the consultation with a radiation rather than medical oncologist were significantly predictive of greater satisfaction at 12-weeks post-consultation. Adjuvant treatment consultations are characterized by a high degree of information-giving by the physician, a predominance of biomedical discussion and relatively minimal time addressing patients' psychosocial concerns. Controlled trials are needed to further identify and address the contextual features of these consultations that enhance patient satisfaction. (c) 2009 John Wiley & Sons, Ltd.

Purpose Multidisciplinary tumor boards (MTBs) have become commonplace. The use, attendance, and function of MTBs need continued assessment and improvement. Methods We prospectively recorded and assessed all cases presented at MTBs between October 2013 and December 2014. Data were collected before and during each MTB. Data were analyzed using SPSS for Windows version 23 (SPSS, Chicago, IL). Results Five hundred three cases were presented: 234 cases (46%) at GI cancer MTBs, 149 cases (29.6%) at breast cancer MTBs, 69 cases (13.7%) at thoracic/head and neck cancer MTBs, and 51 cases (10.7%) at neuro-oncology MTBs. A total of 86.7% of MTB cases were presented to make plans for management. Plans for upfront management were made in 67% of the breast cancer cases, 63% of GI cases, 59% of thoracic/head and neck cases, and 49% of neuro-oncology cases. Three hundred ninety-four cases (78.3%) were presented by medical oncologists, whereas only 74 cases (14.7%) were presented by surgeons, and 10 cases (2%) were presented by radiation oncologists. The majority of MTBs, with the exception of the neurosurgery MTBs, were led by medical oncologists. Surgeons presented the least number of cases but attended the most, and their contributions to discussions and decision making were essential. Conclusion MTBs enhance the multidisciplinary management of patients with cancer. Upfront multidisciplinary decision making should be considered as an indicator of benefit from MTBs, in addition to changes in management plans made at MTBs. Increasing the contributions of surgeons to MTBs should include bringing more of their own cases for discussion. PMID:28717766

This study aimed to ascertain the systemic barriers encountered by oncology health professionals (HPs) working with patients from ethnic minorities to guide the development of a communication skills training programme. Twelve medical and five radiation oncologists and 21 oncology nurses were invited to participate in this qualitative study. Participants were interviewed individually or in a focus group about their experiences working with people from minority backgrounds. All interviews were transcribed verbatim and analysed thematically. HPs encountered language and communication barriers in their interactions with patients and their families, which were perceived to impact negatively on the quality and amount of information and support provided. There was a shortage of, and poor processes for engaging, interpreters and some HPs were concerned about the accuracy of interpretation. HPs expressed a need for training in cultural awareness and communication skills with a preference for face-to-face delivery. A lack of funding, a culture of "learning on the job", and time constraints were systemic barriers to training. Oncologists and oncology nurses encounter complex challenges in clinical interactions with minority patients and their families, including difficulties working with interpreters. Formal training programmes targeted to the development of culturally competent communication skills are required. © 2017 John Wiley & Sons Ltd.

To evaluate whether a consultation skills training (CST) program with oncologists and trainees would improve skills in detecting and responding to patient distress, thereby improving their patients' emotional functioning and reducing psychological distress. Randomized-controlled trial with 29 medical and radiation oncologists from Australia randomized to CST group (n=15) or usual-care group (n=14). The CST consisted of a 1.5-day face-to-face workshop incorporating presentation of principles, a DVD modelling ideal behaviour and role-play practice, and four 1.5h monthly video-conferences. At the CST conclusion, patients of participating doctors were recruited (n=192 in CST group, n=183 in usual-care group), completing telephone surveys at baseline, 1 week and 3 months to assess quality of life, anxiety, depression and unmet psychosocial needs. Despite high patient functioning at baseline, anxiety significantly improved at 1-week follow-up in the CST group, compared to the control group. There were no statistically significant differences in emotional functioning, depression or unmet supportive care need between the groups. Consistent trends for greater improvements were observed in intervention compared to control group patients, suggesting the CST program deserves wider evaluation. Video-conferencing after a short training course may be an effective strategy for delivering CST.

The current attitudes of prostate cancer specialists toward decision aids and their use in clinical practice to facilitate shared decision making are poorly understood. To assess attitudes toward decision aids and their dissemination in clinical practice. A survey was mailed to a national random sample of 1422 specialists (711 radiation oncologists and 711 urologists) in the United States from November 1, 2011, through April 30, 2012. Respondents were asked about familiarity, perceptions, and use of decision aids for clinically localized prostate cancer and trust in various professional societies in developing decision aids. The Pearson χ2 test was used to test for bivariate associations between physician characteristics and outcomes. Similar response rates were observed for radiation oncologists and urologists (44.0% vs 46.1%; P=.46). Although most respondents had some familiarity with decision aids, only 35.5% currently use a decision aid in clinic practice. The most commonly cited barriers to decision aid use included the perception that their ability to estimate the risk of recurrence was superior to that of decision aids (7.7% in those not using decision aids and 26.2% in those using decision aids; P<.001) and the concern that patients could not process information from a decision aid (7.6% in those not using decision aids and 23.7% in those using decision aids; P<.001). In assessing trust in decision aids established by various professional medical societies, specialists consistently reported trust in favor of their respective organizations, with 9.2% being very confident and 59.2% being moderately confident (P=.01). Use of decision aids among specialists treating patients with prostate cancer is relatively low. Efforts to address barriers to clinical implementation of decision aids may facilitate greater shared decision making for patients diagnosed as having prostate cancer.

Purpose: To determine the frequency and clinical significance of previously undetected incidental findings found on computed tomography (CT) simulation images for breast cancer patients. Methods and Materials: All CT simulation images were first interpreted prospectively by radiation oncologists and then double-checked by diagnostic radiologists. The official reports of CT simulation images for 881 consecutive postoperative breast cancer patients from 2009 to 2010 were retrospectively reviewed. Potentially important incidental findings (PIIFs) were defined as any previously undetected benign or malignancy-related findings requiring further medical follow-up or investigation. For all patients in whom a PIIF was detected, we reviewed the clinical recordsmore » to determine the clinical significance of the PIIF. If the findings from the additional studies prompted by a PIIF required a change in management, the PIIF was also recorded as a clinically important incidental finding (CIIF). Results: There were a total of 57 (6%) PIIFs. The 57 patients in whom a PIIF was detected were followed for a median of 17 months (range, 3-26). Six cases of CIIFs (0.7% of total) were detected. Of the six CIIFs, three (50%) cases had not been noted by the radiation oncologist until the diagnostic radiologist detected the finding. On multivariate analysis, previous CT examination was an independent predictor for PIIF (p = 0.04). Patients who had not previously received chest CT examinations within 1 year had a statistically significantly higher risk of PIIF than those who had received CT examinations within 6 months (odds ratio, 3.54; 95% confidence interval, 1.32-9.50; p = 0.01). Conclusions: The rate of incidental findings prompting a change in management was low. However, radiation oncologists appear to have some difficulty in detecting incidental findings that require a change in management. Considering cost, it may be reasonable that routine interpretations are given to those who have not received previous chest CT examinations within 1 year.« less

The aim of this study was to explore the dynamics within second medical opinion consultations in patients with cancer. Semi-structured interviews were held with four oncologists and were subjected to a thematic analysis to define the broad issues. These formed the basis of a survey distributed to Australian medical oncologists. Overall 65 surveys were returned representing an overall response rate of 30% (10% and 63% electronic and hardcopy response rates, respectively). The dynamics in giving second medical opinions are influenced by the collegiate relationships of the doctors. Nearly two-thirds of oncologists believed that the first doctors' treatment and recommendations influenced the outcome of the second opinion, more than one-third believed the outcome was influenced by the relationship between the two doctors, and 41% believed the public nature of a second opinion was influential. In each case, these figures were more than double their assessments of patients' beliefs of these influences. Care was taken not to criticise the primary doctor. Second medical opinions provide an opportunity for oncologists to review medical care and engage in enhanced communication with patients who have additional needs. These consultations do not, however, occur in a vacuum but are influenced by the need to attend to relationships between the patient and their primary doctor and between the doctors themselves. The second medical opinion is embedded within a network of relationships and within the illness journey. © 2010 Blackwell Publishing Asia Pty Ltd.

Purpose To update guidance for health care providers about fertility preservation for adults and children with cancer. Methods A systematic review of the literature published from March 2006 through January 2013 was completed using MEDLINE and the Cochrane Collaboration Library. An Update Panel reviewed the evidence and updated the recommendation language. Results There were 222 new publications that met inclusion criteria. A majority were observational studies, cohort studies, and case series or reports, with few randomized clinical trials. After review of the new evidence, the Update Panel concluded that no major, substantive revisions to the 2006 American Society of Clinical Oncology recommendations were warranted, but clarifications were added. Recommendations As part of education and informed consent before cancer therapy, health care providers (including medical oncologists, radiation oncologists, gynecologic oncologists, urologists, hematologists, pediatric oncologists, and surgeons) should address the possibility of infertility with patients treated during their reproductive years (or with parents or guardians of children) and be prepared to discuss fertility preservation options and/or to refer all potential patients to appropriate reproductive specialists. Although patients may be focused initially on their cancer diagnosis, the Update Panel encourages providers to advise patients regarding potential threats to fertility as early as possible in the treatment process so as to allow for the widest array of options for fertility preservation. The discussion should be documented. Sperm and embryo cryopreservation as well as oocyte cryopreservation are considered standard practice and are widely available. Other fertility preservation methods should be considered investigational and should be performed by providers with the necessary expertise. PMID:23715580

To examine the use of financial incentives related to performance on quality measures reported by oncologists and surgeons associated with a population-based cohort of patients with breast cancer in Los Angeles County, California, and to explore the physician and practice characteristics associated with the use of these incentives among breast cancer care providers. Cross-sectional observational study. Physician self-reported financial arrangements from a survey of 348 medical oncologists, radiation oncologists, and surgeons caring for patients with breast cancer in Los Angeles County (response rate, 76%). Physicians were asked whether they were subject to financial incentives for quality (ie, patient satisfaction surveys and adherence to practice guidelines). We examined the prevalence and correlates of incentives and performed multivariate logistic regression analyses to assess predictors of incentives, controlling for other covariates. Twenty percent of respondents reported incentives based on patient satisfaction, and 15% reported incentives based on guideline adherence. The use of incentives for quality in this cohort of oncologists and surgeons was modest and was primarily associated with staff- or group-model health maintenance organization (HMO) settings. In other settings, important predictors were partial physician ownership interest, large practice size, and capitation. Most cancer care providers in Los Angeles County outside of staff- or group-model HMOs are not subject to explicit financial incentives based on quality-of-care measures. Those who are, seem more likely to be associated with large practice settings. New approaches are needed to direct financial incentives for quality toward specialists outside of staff- or group-model HMOs if pay-for-performance programs are to succeed in influencing care.

Aurora Health Care (AHC) is the largest health care system in Wisconsin, with 14 acute care hospitals. In early 2010, a group of 18 medical oncologists became affiliated with AHC. This affiliation added 13 medical oncology infusion clinics to our existing 12 sites. In the era of health care reform and declining reimbursement, we need an objective method and criteria to evaluate our 25 outpatient medical oncology sites. We developed financial, clinical, and strategic tools for the evaluation and management of our cancer subservice lines and outpatient sites. The key to our success has been the direct involvement of stakeholders with a vested interest in the services in the selection of the criteria and evaluation process. We developed our objective metrics for evaluation based on strategic, financial, operational, and patient experience criteria. Strategic criteria included: population trends, full-time equivalent (FTE) medical oncologists/primary care physicians, FTE radiation oncologists, FTE oncologic surgeons, new annual cases of patients with cancer, and market share trends. Financial criteria per site included: physician work relative value units, staff FTE by type, staff salaries, and profit and loss. Operational criteria included: facility by type (clinic v hospital based), hours of operation, and facility detail (eg, No. of chairs, No. of procedure and examination rooms, square footage). Patient experience criteria included: nursing model primary/nurse navigators, multidisciplinary support at site, Press Ganey (South Bend, IN; health care performance improvement company) results, and employee engagement score. The outcome of our data analysis has resulted in the development of recommendations for AHC senior leadership and geographic market leadership to consider the consolidation of four sites (phase one, four sites; phase two, two sites) and priority strategic sites to address capacity issues that limit growth. The recommendations if implemented would result in significant cost savings, currently being quantified as a result of consolidation and improved efficiency. A reinvestment of these cost savings would be required to address facility expansion and program enhancement to maximize patient-centered expert care consistently across all of our remaining sites of service.

Trainee radiation oncologists must master a substantial body of skills and knowledge to become competent specialists. The resources available to support this are limited. We surveyed the 90 registrars enrolled in the Royal Australian and New Zealand College of Surgeons (RANZCR) radiation oncology training programme to obtain a range of information about their learning activities (with a significant focus on part 1 teaching). Responses were received from 59 registrars (66% of those eligible). Trainees reported spending a median 2.5 h per week (range 0-10 h) in formal teaching activities. With regard to part 1 exam preparation, 83% reported having had physics teaching--the median quality was 5/7; 88% had radiobiology teaching--the median quality was 4/7; 52% had anatomy teaching--the median quality was 3/7. Registrars training within the RANZCR radiation oncologists training programme perceive their own clinical learning environment as generally good; however' 50% of respondents felt that more teaching was needed for part 1 subjects. This compared with only 19% of respondents who felt that more teaching was required for part 2 exam preparation. Innovative solutions, such as centralized web-based teaching, may help to address weaknesses in part 1 teaching. With increasing demands on radiation oncologists and trainees it will be important to monitor learning environments.

The role of medical physics in prostate cancer radiation therapy.

PubMed

Fiorino, Claudio; Seuntjens, Jan

2016-03-01

Medical physics, both as a scientific discipline and clinical service, hugely contributed and still contributes to the advances in the radiotherapy of prostate cancer. The traditional translational role in developing and safely implementing new technology and methods for better optimizing, delivering and monitoring the treatment is rapidly expanding to include new fields such as quantitative morphological and functional imaging and the possibility of individually predicting outcome and toxicity. The pivotal position of medical physicists in treatment personalization probably represents the main challenge of current and next years and needs a gradual change of vision and training, without losing the traditional and fundamental role of physicists to guarantee a high quality of the treatment. The current focus issue is intended to cover traditional and new fields of investigation in prostate cancer radiation therapy with the aim to provide up-to-date reference material to medical physicists daily working to cure prostate cancer patients. The papers presented in this focus issue touch upon present and upcoming challenges that need to be met in order to further advance prostate cancer radiation therapy. We suggest that there is a smart future for medical physicists willing to perform research and innovate, while they continue to provide high-quality clinical service. However, physicists are increasingly expected to actively integrate their implicitly translational, flexible and high-level skills within multi-disciplinary teams including many clinical figures (first of all radiation oncologists) as well as scientists from other disciplines.

Ellsworth, Susannah G.; Alcorn, Sara R., E-mail: salcorn2@jhmi.edu; Hales, Russell K.

Purpose: This study evaluates outcomes and patterns of care among patients receiving radiation therapy (RT) for bone metastases at a high-volume academic institution. Methods and Materials: Records of all patients whose final RT course was for bone metastases from April 2007 to July 2012 were identified from electronic medical records. Chart review yielded demographic and clinical data. Rates of complicated versus uncomplicated bone metastases were not analyzed. Results: We identified 339 patients whose final RT course was for bone metastases. Of these, 52.2% were male; median age was 65 years old. The most common primary was non-small-cell lung cancer (29%). Most patientsmore » (83%) were prescribed ≤10 fractions; 8% received single-fraction RT. Most patients (52%) had a documented goals of care (GOC) discussion with their radiation oncologist; hospice referral rates were higher when patients had such discussions (66% with vs 50% without GOC discussion, P=.004). Median life expectancy after RT was 96 days. Median survival after RT was shorter based on inpatient as opposed to outpatient status at the time of consultation (35 vs 136 days, respectively, P<.001). Hospice referrals occurred for 56% of patients, with a median interval between completion of RT and hospice referral of 29 days and a median hospice stay of 22 days. Conclusions: These data document excellent adherence to American Society for Radiation Oncolology Choosing Wisely recommendation to avoid routinely using >10 fractions of palliative RT for bone metastasis. Nonetheless, single-fraction RT remains relatively uncommon. Participating in GOC discussions with a radiation oncologist is associated with higher rates of hospice referral. Inpatient status at consultation is associated with short survival.« less

This is a pilot study that aims to elucidate regional disparities in the distribution of medical resources in Japan. For this purpose, we employed the Gini coefficient (GC) in order to analyze the distribution of radiotherapy resources, which are allocated to each prefecture in Japan depending on the size of its population or physical area. Our study used data obtained from the 2005 and 2007 national surveys on the structure of radiation oncology in Japan, conducted by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO). Our analysis showed that the regional disparities regarding the radiation oncologists and radiotherapy technologists were small, and concluded that such resources were almost equitably distributed. However, medical physicists are inequitably distributed. Thus, policymakers should create and implement measures to train and retain medical physicists in areas with limited radiotherapy resources. Further, almost 26% of the secondary medical service areas lacked radiotherapy institutions. We attribute this observation to the existence of tertiary medical service areas, and almost all of prefectures face a shortage of such resources. Therefore, patients' accessibility to these resources in such areas should be improved.

The aim of this study was to determine the self-reported prevalence of stress, job satisfaction and burnout among radiation oncologists in Australia and New Zealand. A secondary aim was to determine the association between stress and satisfaction parameters with burnout. An anonymous online survey was distributed to all radiation oncologists listed on Royal Australian and New Zealand College of Radiologists membership database. There were 37 Likert scale questions on stress, 17 Likert scale questions on job satisfaction and burnout assessed by the Maslach Burnout Inventory - Human Services Survey (MBI-HSS). A principal component analysis was done for stress and satisfaction to identify specific areas. Independent samples t-tests and analysis of variances were done. There were 220 responses out of 348 eligible respondents (63.2% response rate).For stress, a principal component analysis identified five areas: delivery demands, demands on time, continuing professional development (CPD), value and security, and interpersonal/teaching demands. Specialist radiation oncologists were more stressed by value and security than generalists (P < 0.01). Lung cancer specialists had higher levels of stress associated with delivery demands, demands on time and CPD compared with others (P = 0.01). Those over 60 years were less stressed by delivery demands (P = 0.02), demands on time (P = 0.01) and CPD (P = 0.01) than their younger colleagues. Four satisfaction factors were identified in the principal component analysis: resources/remuneration, status/security, delivery of services and professional activities. [Correction added on 15 August 2014, after first online publication: stress/security was replaced with status/security.] Males and Australian radiation oncologists were more satisfied with professional activities (P = 0.02). Brachytherapy specialists were more satisfied with status/security (P = 0.01) while those interested in urology were more satisfied with resources/renumeration (P = 0.01) and professional activities (P = 0.01). The burnout results revealed at least 48.5% of respondents scoring highly in at least one of the three measures of burnout (emotional exhaustion, depersonalisation and personal accomplishment) while 37.5% scoring highly in the emotional exhaustion and depersonalisation subscales. Public sector radiation oncologists had higher levels of emotional exhaustion and lower levels of personal accomplishment than their private sector counterparts, while those interested in lung cancer had higher levels of emotional exhaustion. Multiple regression analysis revealed that the stress subscale demands on time had a significant effect on emotional exhaustion. Higher CPD stress and interpersonal/teaching demands increased the feeling of depersonalisation, while satisfaction with delivery of services was associated with lower levels of depersonalisation and higher levels of personal accomplishment. This first study of stress, satisfaction and burnout among radiation oncologists in Australia and New Zealand had a reasonable response rate and identified specific areas of stress and satisfaction. Nearly half of the respondents scored highly in one burnout subscale. Some of the stress and satisfaction subscales correlated with certain aspects of burnout. Further research will be undertaken to refine the stress and satisfaction parameters and address burnout interventions. © 2014 The Royal Australian and New Zealand College of Radiologists.

Purpose: Target delineation using only CT information introduces large geometric uncertainties in radiotherapy for lung cancer. Therefore, a reduction of the delineation variability is needed. The impact of including a matched CT scan with 2-[{sup 18}F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) and adaptation of the delineation protocol and software on target delineation in lung cancer was evaluated in an extensive multi-institutional setting and compared with the delineations using CT only. Methods and Materials: The study was separated into two phases. For the first phase, 11 radiation oncologists (observers) delineated the gross tumor volume (GTV), including the pathologic lymph nodes of 22more » lung cancer patients (Stages I-IIIB) on CT only. For the second phase (1 year later), the same radiation oncologists delineated the GTV of the same 22 patients on a matched CT-FDG-PET scan using an adapted delineation protocol and software (according to the results of the first phase). All delineated volumes were analyzed in detail. The observer variation was computed in three dimensions by measuring the distance between the median GTV surface and each individual GTV. The variation in distance of all radiation oncologists was expressed as a standard deviation. The observer variation was evaluated for anatomic regions (lung, mediastinum, chest wall, atelectasis, and lymph nodes) and interpretation regions (agreement and disagreement; i.e., >80% vs. <80% of the radiation oncologists delineated the same structure, respectively). All radiation oncologist-computer interactions were recorded and analyzed with a tool called 'Big Brother.' Results: The overall three-dimensional observer variation was reduced from 1.0 cm (SD) for the first phase (CT only) to 0.4 cm (SD) for the second phase (matched CT-FDG-PET). The largest reduction in the observer variation was seen in the atelectasis region (SD 1.9 cm reduced to 0.5 cm). The mean ratio between the common and encompassing volume was 0.17 and 0.29 for the first and second phases, respectively. For the first phase, the common volume was 0 in 4 patients (i.e., no common point for all GTVs). In the second phase, the common volume was always >0. For all anatomic regions, the interpretation differences among the radiation oncologists were reduced. The amount of disagreement was 45% and 18% for the first and second phase, respectively. Furthermore, the mean delineation time (12 vs. 16 min, p < 0.001) and mean number of corrections (25 vs. 39, p < 0.001) were reduced in the second phase compared with the first phase. Conclusion: For high-precision radiotherapy, the delineation of lung target volumes using only CT introduces too great a variability among radiation oncologists. Implementing matched CT-FDG-PET and adapted delineation protocol and software reduced observer variation in lung cancer delineation significantly with respect to CT only. However, the remaining observer variation was still large compared with other geometric uncertainties (setup variation and organ motion)« less

Professor Hassan K. Awwad; The Father of Radiation Oncology and Radiobiology in Egypt and the Arab World, His Good Deeds Last Forever and Inspire us for the Future.

Our most respected professor Hassan K. Awwad passed away on January 5th, 2007, at the age of 81. He was considered as the father of radiotherapy in Egypt. He was always named "The Professor", as he was the founder of the radiotherapy departments at the National Cancer Institute, Cairo University&Faculty of Medicine, Alexandria University. He also shared in developing NEMROCK (Kasr El Aini Center of Radiation Oncology and Nuclear Medicine), the place where he graduated and worked during his early years of experience. He, together with professor Reda Hamza, dean of NCI, Cairo at that time, had initiated 7 oncology centers all over Egypt, from Aswan in the South to Dammietta and Damanhour in the North. These 7 centers were developed by the Ministry of Health. Prof. Awwad and Prof. Hamza were responsible for facility providing and plans. They chose all the necessary equipment, tools and personnel. These centers were in action since 1988 and are currently taking care of the oncology patients in a wide area of the country. Prof. Awwad graduated from the Faculty of medicine, Cairo University, in 1949. He had his Medical Doctorate (MD) in Radiotherapy from Alexandria University in 1956. The International Atomic Energy Agency (IAEA) awarded him fellowships in France (Institute Gustave Rossy) to gain experience in brachytherapy in 1956 and 1971, England 1956, 1959. Another fellowship was awarded to Prof Awwad in Harvard University (Peter Bent Brigham Hospital) in radiobiology and radiotherapy during the years 1964-1965. He personally and with other members of the National Cancer Institute gave much of their efforts and time to teach, train and guide young radiotherapists, biologists, physicists and radiation therapists through direct on-hand teaching and training as well as holding training courses for radiation oncologists, physicists and technologists. He insisted to ensure its regularity 4 times yearly. These courses trained a lot of personnel from all over Egypt, Sudan, Libya, Palastine, Iraq, Uganda, Nigeria and other countries. He himself had many teaching missions in different Arab countries (Saudi Arabia, Kuwait and others) for the sake of groups of his students that could not come to Egypt. He served as the head of the Department of Radiation Oncology for more than 15 years (1970-1985), full time Professor in Radiation Oncology and Radiobiology (1985-2007), Professor of Radiotherapy, Alexandria University (1954-1970), Chief of the Department of Nuclear Medicine, Medical Research Institute, University of Alexandria (1963-1964), Chief of the Radiotherapy Unit in the Heliopolis Hospital, Ministry of Public Health, 1985-2007. He was co-founder of the Egyptian Society of Cancer and acted as vice present and head of the scientific committee of the society. He shared the activities of many Egyptian, Arab and international scientific societies. His activities in these societies were great. Prof. Awwad had direct contact with his students that never ended, even after some of them left to work in other places in USA, Canada, Europe or Arab Countries. His students' specialty varied between radiobiology, pharmacology, biochemistry, tumor biology, radiation oncology, medical oncology and surgical oncology. Prof. Awwad had more than 100 published articles on hypoxia and hypoxic cell radiosensitizers, biology of growth of human tumors, biology and clinical models of the time factor in external beam radiotherapy, biology and mathematical models of time factor in brachytherapy, radioactive dynamic cancer studies of plasma protein metabolism, radioactive dynamic factor studies of blood disorders and lymphoma, radiation damage of DNA and normal tissues,head and neck cancer, bladder cancer, breast cancer, cervical cancer and development and optimization of clinical radiotherapy. He had continuous cooperation and collaboration with many of the great scientists and clinicians in Holland, France, United Kingdom, USA and Japan. He continued to exchange ideas with these great people all through his life and till the last moments of his extended fruitful life. Prof. Awwad wrote many books for a wide diversity of readers, for the lay people in Arabic, for radiographers, young oncologist, and the highly experienced radiation oncologists and radiobiologists. His book "Radiation Oncology: Radiobiological and Physiobiological Perspectives" was a real translation of radiobiology language to the oncologist and at the same time translation of the oncologist language to the biologist. This book ended with establishing a common language for both teams. In addition, it led other books in these specialties to communicate with the same language. The good news is that Prof. Awwad had completed the second edition of this book just before passing away. This second edition is really a totally new book coping with the advancement of knowledge reached till the end of 2006. We are sure that this book with all other good deeds performed by Prof. Awwad, will keep his memory in Egypt as well as elsewhere in the whole world.

Certain jurisdictions in Canada legally require that physicians report unfit drivers. Physician attitudes and patterns of practice have yet to be evaluated in Canada for patients with brain tumours. We conducted a survey of 97 radiation oncologists, eliciting demographics, knowledge of reporting laws, and attitudes on reporting guidelines for unfit drivers. Eight scenarios with varying disability levels were presented to determine the likelihood of a patient being reported as unfit to drive. Statistical comparisons were made using the Fisher exact test. Of physicians approached, 99% responded, and 97 physicians participated. Most respondents (87%) felt that laws in their province governing the reporting of medically unfit drivers were unclear. Of the responding physicians, 23 (24%) were unable to correctly identify whether their province had mandatory reporting legislation. Physicians from provinces without mandatory reporting legislation were significantly less likely to consider reporting patients to provincial authorities (p = 0.001), and for all clinical scenarios, the likelihood of reporting significantly depended on the physician's provincial legal obligations. The presence of provincial legislation is of primary importance in determining whether physicians will report brain tumour patients to drivers' licensing authorities. In Canada, clear guidelines have to be developed to help in the assessment of whether brain tumour patients should drive.

It is common for cancer patients to use complementary and alternative medicine (CAM). This study was designed to explore China's oncologists' knowledge, attitudes and clinical practices regarding CAM use by their patients. An online survey was conducted of China's oncologists. Among 11,270 participants who completed the online survey, 6,007 (53.3%) were identified as oncologists. Most were men (75.2%), with a mean age of 33.4 (standard deviation: 6.5) years. The 6,007 oncologists discussed with 36.5% of their patients about CAM. Most of them (75.6%) did not want to initiate discussions due to lack of knowledge on CAM. Oncologists estimated that 40.0% of their patients used CAM treatments. Oncologists reported that 28.7% of their patients underwent anticancer therapy with the concurrent use of CAM. Four out of five of the responding oncologists self-reported inadequate knowledge and only 22.0% reported receiving professional education on CAM. Nearly half (44.9%) of the oncologists believed CAM treatment was effective for symptoms and treatment of cancer. Physician factors associated with initiating discussions with patients about CAM use included sex, age (≥ 33 years), medical license for traditional Chinese medicine, enough knowledge and professional education experience. China's oncologists infrequently discussed with their patients about CAM due to lack of knowledge. Most of the oncologists did not encourage CAM use.

SU-F-J-161: Prostate Contouring in Patients with Bilateral Hip Prostheses: Impact of Using Artifact-Reduced CT Images and MRI

DOE Office of Scientific and Technical Information (OSTI.GOV)

Elzibak, A; Loblaw, A; Morton, G

Purpose: To investigate the usefulness of metal artifact reduction in CT images of patients with bilateral hip prostheses (BHP) for contouring the prostate and determine if the inclusion of MR images provides additional benefits. Methods: Five patients with BHP were CT scanned using our clinical protocol (140kV, 300mAs, 3mm slices, 1.5mm increment, Philips Medical Systems, OH). Images were reconstructed with the orthopaedic metal artifact reduction (O-MAR) algorithm. MRI scanning was then performed (1.5T, GE Healthcare, WI) with a flat table-top (T{sub 2}-weighted, inherent body coil, FRFSE, 3mm slices with 0mm gap). All images were transferred to Pinnacle (Version 9.2, Philipsmore » Medical Systems). For each patient, two data sets were produced: one containing the O-MAR-corrected CT images and another containing fused MRI and O-MAR-corrected CT images. Four genito-urinary radiation oncologists contoured the prostate of each patient on the O-MAR-corrected CT data. Two weeks later, they contoured the prostate on the fused data set, blinded to all other contours. During each contouring session, the oncologists reported their confidence in the contours (1=very confident, 3=not confident) and the contouring difficulty that they experienced (1=really easy, 4=very challenging). Prostate volumes were computed from the contours and the conformity index was used to evaluate inter-observer variability. Results: Larger prostate volumes were found on the O-MAR-corrected CT set than on the fused set (p< 0.05, median=36.9cm{sup 3} vs. 26.63 cm{sup 3}). No significant differences were noted in the inter-observer variability between the two data sets (p=0.3). Contouring difficulty decreased with the addition of MRI (p<0.05) while the radiation oncologists reported more confidence in their contours when MRI was fused with the O-MAR-corrected CT data (p<0.05). Conclusion: This preliminary work demonstrated that, while O-MAR correction to CT images improves visualization of anatomy, the addition of MRI enhanced the oncologists’ confidence in contouring the prostate in patients with BHP.« less

Disparities in treatment and mortality for colorectal cancer (CRC) may reflect differences in access to specialized care or other characteristics of the area where an individual lives. Surveillance, Epidemiology and End Results Program-Medicare data for seniors diagnosed with CRC were linked to area measures of the sociodemographic characteristics and the capacity of surgeons, medical oncologists, and radiation oncologists. Outcomes included receipt of stage-appropriate CRC care and mortality. After adjustment, blacks and Hispanics were less likely than whites to undergo surgery (odds ratio [OR] 0.57, 95% confidence interval (CI) 0.52-0.63 and OR 0.82, 95% CI 0.70-0.95, respectively). Individuals who lived in areas with the highest tertile of surgeon capacity were more likely to undergo resection than those in the lowest, and use of surgery declined as the percentage of blacks in the area increased. Adjustment for the area measures resulted in a modest decline in disparities in care relative to whites (5.3% for black). Blacks also experienced greater all-cause and cancer-specific mortality than whites. Further adjustment for area sociodemographics and surgeon capacity reduced the disparity in mortality between blacks and whites. Although there was a similar black/white disparity in the use of adjuvant chemotherapy, the disparity remained after adjustment for area characteristics, although use of chemotherapy was greater in areas with the greatest capacity of medical oncologists. Sociodemographic characteristics and measures of the availability of specialized cancer providers in the area in which an individual resides modestly mediated disparities in the receipt of CRC care and mortality, suggesting that other factors may also be important.

To document the preliminary validity of a new informed consent form (ICF) model in terms of face/content validity and feasibility, to collect patients' and oncologists' opinions on it, and to explore physicians' and patients' "knowledge", "opinions" about "the information exchanged". The working group for informed consent promoted by the Italian Association of Medical Oncology developed a new ICF model which was tested in ten Italian cancer centers. Patients and physicians received questionnaires on the new ICF model. Twenty-six independent oncologists were interviewed to collect their opinions. Seventy eight cancer patients were enrolled: about 90% reported having received information about diagnosis and therapy and 80% about prognosis. About 63% of oncologists had no difficulty in administering the ICF. Oncologists used "correct terms" about diagnosis in 92% of patients with localized disease and in 90% with metastasis and about therapy in respectively 75.7% and 80%. About prognosis, oncologists used "vague" and "no information-no pertinent terms" in 79% of patients with localized disease and 92.5% of patients with metastasis. The ICF seemed to have sufficient validity and feasibility. This ICF model could mean that patients require oncologists to spend more time explaining the diagnosis, prognosis and treatment, increasing patient's opportunities to participate actively in the care process.

Post-treatment cancer care is often fragmented and of suboptimal quality. We explored factors that may affect cancer survivors' post-treatment care coordination, including oncologists' use of electronic technologies such as e-mail and integrated electronic health records (EHRs) to communicate with primary care physicians (PCPs). We used data from a survey (357 respondents; participation rate 52.9%) conducted in 2012-2013 among medical oncologists caring for patients in a large US study of cancer care delivery and outcomes. Oncologists reported their frequency and mode of communication with PCPs, and role in providing post-treatment care. Seventy-five per cent said that they directly communicated with PCPs about post-treatment status and care recommendations for all/most patients. Among those directly communicating with PCPs, 70% always/usually used written correspondence, while 36% always/usually used integrated EHRs; telephone and e-mail were less used. Eighty per cent reported co-managing with PCPs at least one post-treatment general medical care need. In multivariate-adjusted analyses, neither communication mode nor intensity were associated with co-managing survivors' care. Oncologists' reliance on written correspondence to communicate with PCPs may be a barrier to care coordination. We discuss new research directions for enhancing communication and care coordination between oncologists and PCPs, and to better meet the needs of cancer survivors post-treatment. © 2017 John Wiley & Sons Ltd.

Marijuana to prevent nausea and vomiting in cancer patients: a survey of clinical oncologists.

Marijuana, if rescheduled by the Drug Enforcement Agency, would be the only Food and Drug Administration (FDA)-approved drug to be administered by smoking. American physicians need timely, factual information about probable usage patterns and potential adverse effects of medical marijuana, and a factual complete review of the literature on the subject. We mailed a survey to 1,500 American clinical oncologists. Of particular interest was whether and how often in the past 24 months these physicians recommended smoked marijuana, synthetic tetrahydrocannabinol, or 5-HT3 (serotonin) antagonists (ondansetron [Zofran], granisetron [Kytril]) for their patients. We also inquired whether and how often the oncologists would prescribe marijuana in the form of cigarettes, were it to be FDA-approved. Completed surveys were received from 1,122 (75%) of the oncologists. The percentages of oncologists who prescribed or recommended selected antiemetics more than five times between 1992 and 1994 were 98% for 5-HT, antagonists, 6% for dronabinol (Marinol), and 1% for smoked marijuana. We also found that 332 (30%) of the oncologist-respondents to this nationwide survey supported rescheduling of marijuana for medical purposes; however, two thirds (67%) of the 332 respondents who were in favor of rescheduling estimated that they would write less than one prescription per month for marijuana cigarettes. A comprehensive literature review failed to provide persuasive evidence to recommend marijuana as a needed antiemetic medicine.

Breast cancer offers several opportunities for reducing use of ineffective practices based on American Society of Clinical Oncology guidelines. We assessed oncologist-perceived factors associated with use of one such practice-serum tumor markers for post-treatment breast cancer surveillance-focusing on medical oncologists with high, medium, or low test use. Using a mixed-methods design, we identified patients who had been treated for early-stage breast cancer diagnosed between January 1, 2009, and December 31, 2012, within Kaiser Permanente Southern California and calculated the number of tests ordered from January 1, 2010, to December 31, 2014. We identified oncologists with high, medium, or low use and subsequently performed semistructured interviews. We used patient satisfaction data to assess association between pattern of use and satisfaction score. We identified 7,363 patients, with 40,114 tests ordered. High-use oncologists were defined as those ordering at least one test annually for 35% of patients or more, low-use oncologists as those ordering at least one test for 5% of patients or less; 42% of oncologists were high, 27% low, and 31% medium users. We interviewed 17 oncologists: six high, eight low, and three medium users. Factors associated with high use included: perceived patient anxiety, oncologist anxiety, belief that there was nothing else to offer, concern about satisfaction, patient competition, peer use, and system barriers. Factors associated with low use included: beliefs about consequences (eg, causes harms) and medical center culture (eg, collective decision to follow guidelines). We found no association between satisfaction score and pattern of use. Barriers to deimplementation are numerous and complex. Traditional strategies of practice change alone are unlikely to be effective. Multifaceted, multilevel strategies deployed to address patient-, clinician-, and system-related barriers may be required.

Gorlin-Goltz syndrome is a genetically predisposed disease characterised by multiple basal cell carcinomas, odontogenic keratocysts and ectopic calcifications. The aim of this study was to show successful treatment of a 37-year-old male patient by cooperation between different dental and medical specialists. Because of the recurrence of a large basal cell carcinoma after multiple operations and a total dose telecobalt irradiation of 66 Gy, the patient's nose was ablated, with resection of the upper lip and part of the maxilla. The intraoral prosthetic treatment helped to restore the subtotal edentulousness. In order to enhance the application of the dental prosthesis, an Abbe plasty was performed at the second stage of surgery. As previous irradiation of the area precluded the use of facial implants immediately after the intraoral treatment, a temporary artificial nose prosthesis was created. The patient tolerated the procedures well and is completely disease-free 12 months after the surgery. Besides presenting a rare and complicated case of Gorlin-Goltz syndrome, the main purpose of this report is to show that, if different specialists in a dental-clinical team (maxillofacial surgeon, oncologist, radiation oncologist, prosthodontist and psychiatrist) combine their skills and expertise, successful management is possible even in a challenging complex case.

Medical physics in radiotherapy: The importance of preserving clinical responsibilities and expanding the profession's role in research, education, and quality control

PubMed Central

Malicki, Julian

2015-01-01

Medical physicists have long had an integral role in radiotherapy. In recent decades, medical physicists have slowly but surely stepped back from direct clinical responsibilities in planning radiotherapy treatments while medical dosimetrists have assumed more responsibility. In this article, I argue against this gradual withdrawal from routine therapy planning. It is essential that physicists be involved, at least to some extent, in treatment planning and clinical dosimetry for each and every patient; otherwise, physicists can no longer be considered clinical specialists. More importantly, this withdrawal could negatively impact treatment quality and patient safety. Medical physicists must have a sound understanding of human anatomy and physiology in order to be competent partners to radiation oncologists. In addition, they must possess a thorough knowledge of the physics of radiation as it interacts with body tissues, and also understand the limitations of the algorithms used in radiotherapy. Medical physicists should also take the lead in evaluating emerging challenges in quality and safety of radiotherapy. In this sense, the input of physicists in clinical audits and risk assessment is crucial. The way forward is to proactively take the necessary steps to maintain and advance our important role in clinical medicine. PMID:25949219

Radiation therapy is a keystone to improve survival and quality of life in breast cancer patients. In Mexico, however, scarce information is available on the obstacles faced by radio-oncologists to provide appropriate treatment. To determine the most frequent issues faced by physicians to provide radiation therapy for metastatic breast cancer in Mexico. A survey of 16 multiple-choice questions to be answered electronically by 167 radio-oncologists currently working in Mexico was designed and thereafter analyzed for differences between private and public practices, based on the responses from the surveyed participants. 98.5% of surveyed responders attended patients with breast cancer. We observed a significant difference between private vs. public practice for the main difficulties in providing radiation therapy, with an increased frequency (85.8%) of "treatment cost by itself" in private practice vs. 50.7% in public practice (p < 0.05). Significant differences were observed in the "Time to initiate treatment" question, with "Less than one week" as the response in 86% of those physicians in private practice vs. 50% for those in public practice (p < 0.001). Using a survey targeted at radio-oncologists, we analyzed the most important obstacles for accessing radiation therapy for metastatic breast cancer in Mexico. This information may be useful for healthcare decisions related to radiation therapy in women with breast cancer in Mexico.

Purpose: To characterize the practice type and location of radiation oncology (RO) residents graduating in 2013. Methods and Materials: Graduates completing RO residency in 2013 were identified, and for each, postgraduate practice setting (academic vs private practice) and location were identified. Characteristics of the graduates, including details regarding their institutions of medical school and residency education, were collected and analyzed. Results: Data were obtained from 146 of the 154 RO graduates from the class of 2013. Employment data were available for 142 graduates. Approximately one-third of graduates were employed in the same state as residency (36.6%), approximately two-thirds (62.0%) in themore » same region as residency, and nearly three-fourths (73.9%) in the same region as medical school or residency completion. Of the 66 graduates (46.5%) working in academics, 40.9% were at the same institution where they completed residency. Most trainees (82.4%) attended medical schools with RO residency programs. Conclusions: Although personal factors may attract students to train in a particular area, the location of medical school and residency experiences may influence RO graduate practice location choice. Trends in the geographic distribution of graduating radiation oncologists can help identify and better understand disparities in access to RO care. Steps to improve access to RO care may include interventions at the medical student or resident level, such as targeting students at medical schools without associated residency programs and greater resident exposure to underserved areas.« less

Of the 66 graduates (46.5%) working in academics, 40.9% were at the same institution where they completed residency. Most trainees (82.4%) attended medical schools with RO residency programs. Although personal factors may attract students to train in a particular area, the location of medical school and residency experiences may influence RO graduate practice location choice. Trends in the geographic distribution of graduating radiation oncologists can help identify and better understand disparities in access to RO care. Steps to improve access to RO care may include interventions at the medical student or resident level, such as targeting students at medical schools without associated residency programs and greater resident exposure to underserved areas.

The "International Summer School on Experimental and Clinical Oncology for Medical Students" is organised at the Medical University of Vienna to teach a multidisciplinary approach to oncology to medical students in the final phase of their studies. The program includes biology, diagnosis, clinical and psycho-oncology. Lectures are given by medical, radiation and surgical oncologists. Teaching includes case reports, poster presentations and role-play. As part of the organising committee, Austrian students organise a social program. Since 1999, six courses have been held (147 students from 19 countries). Students recorded high satisfaction with organisation, scientific content and topic range. Case presentations, poster presentations and role-play were very useful. Early criticism that the program was too intense (long lectures and little interaction) has been answered. The summer school has a high degree of acceptance and is a very useful tool to teach medical students about oncology and approaching a cancer patient.

Clinical trials are vital for evidence-based cancer care. Oncologist engagement in clinical trials has an effect on patient recruitment, which in turn can affect trial success. Identifying barriers to clinical trial participation might enable interventions that could help to increase physician participation. To assess factors affecting physician engagement in oncology trials, a national survey was conducted using the online SurveyMonkey tool (SurveyMonkey, San Mateo, CA, U.S.A.; http://www.surveymonkey.com). Physicians associated with the Canadian Cancer Clinical Trials Network and the Canadian Cancer Trials Group were asked about their specialty, years of experience, barriers to participation, and motivating interventions, which included an open-ended question inviting survey takers to suggest interventions. The survey collected 207 anonymous responses. Respondents were predominantly medical oncologists (46.4%), followed by radiation oncologists (24.6%). Almost 70% of the respondents had more than 10 years of experience. Significant time constraints included extra paperwork (77%), patient education (54%), and extended follow-up or clinic visits (53%). Timing of events within trials was also a barrier to participation (55%). Most respondents favoured clinical work credits (72%), academic credits (67%), a clinical trial alert system (75%), a regular meeting to review trial protocols (65%), and a screening log to aid in patient accrual (67%) as motivational strategies. Suggested interventions included increased support staff, streamlined regulatory burden, and provision of greater funding for trials and easier access to ancillary services. The present study confirms that Canadian oncologists are willing to participate in clinical research, but face multiple barriers to trial participation. Those barriers could be mitigated by the implementation of several interventions identified in the study.

In localisation of radiotherapy treatment field, the oncologist is present at the simulator to approve treatment details produced by the therapist. Problems may arise if the oncologist is not available and the patient requires urgent treatment. The development of a tele-localisation system is a potential solution, where the oncologist uses a personal digital assistant (PDA) to localise the treatment field on the image sent from the simulator through wireless communication and returns the information to the therapist after his or her approval. Our team developed the first tele-localisation prototype, which consisted of a server workstation (simulator) for the administration of digital imaging and communication in medicine localisation images including viewing and communication with the PDA via a Wi-Fi network; a PDA (oncologist's site) installed with the custom-built programme that synchronises with the server workstation and performs treatment field editing. Trial tests on accuracy and speed of the prototype system were conducted on 30 subjects with the treatment regions covering the neck, skull, chest and pelvis. The average time required in performing the localisation using the PDA was less than 1.5 min, with the blocked field longer than the open field. The transmission speed of the four treatment regions was similar. The average physical distortion of the images was within 4.4% and the accuracy of field size indication was within 5.3%. Compared with the manual method, the tele-localisation system presented with an average deviation of 5.5%. The prototype system fulfilled the planned objectives of tele-localisation procedure with reasonable speed and accuracy. © 2012 The Authors.

Early integration of palliative care in oncology practice ("simultaneous care", SC) has been shown to provide better care resulting in improved quality-of-life and also survival. We evaluated the opinions of Italian Association of Medical Oncology (AIOM) members. A 37-item questionnaire was delivered to 1119 AIOM members. Main areas covered were: social, ethical, relational aspects of disease and communication, training, research, organizational and management models in SC. Three open questions explored the definition of Quality of Life, Medical Oncologist and Palliative Care. Four hundred and forty-nine (40.1%) medical oncologists returned the questionnaires. Forty-nine percent stated they address non-curability when giving a diagnosis of metastatic tumor, and 43% give the information only to patients who clearly ask for it. Fifty-five percent say the main formative activity in palliative medicine came from attending meetings and 90% agree that specific palliative care training should be part of the core curriculum in oncology. Twenty-two percent stated they consulted guidelines for symptom management, 45% relied upon personal experience and 26% make a referral to a palliative care specialist. Seventy-four percent were in favor of more research in palliative medicine. An integration between Units of Oncology and Palliative Care Services early in the course of advanced disease was advocated by 86%. Diverse and multifaceted definitions were given for the concepts of Quality of Life, Palliative Care and Medical Oncologist. SC is felt as an important task, as well as training of medical oncologists in symptom management and research in this field.

The first nationwide, population-based study of Swedish pediatric oncologists was conducted in 2006 and it revealed that various aspects of their life satisfaction obviously influenced their stress-resilience. This second part of the study, with a response rate of 89% in the target group, therefore, focused on their life satisfaction and the role of personality, work-related aspects, and emotional distress related to type of medical center and gender. This descriptive study was based on a cross-sectional mail survey with questionnaires involving 90 pediatric oncologists. Using hierarchical regression models, their total, present, past, and future life satisfaction was analyzed. The vast majority (76.7%) stated that working in this medical field was very stimulating for their personal development. Male pediatricians were more satisfied with their present lives and physicians working at academic medical centers were more confident about the future. Some oncologists (13.4%), in particular females at non-academic medical centers, needed professional help dealing with work-related psychological problems. Personality trait (Hedonic Capacity) and low levels of depression contributed to every aspect of overall life satisfaction. Work-related aspects influenced present and future life satisfaction. The models explained between 5% and 43% of the variance in life satisfaction in the whole group. Pediatric oncologists face life-threatening conditions and psychosocial issues factors that may negatively influence their life satisfaction. This study group, a single population of physicians, is characterized by an optimistic attitude and stable emotional status pointing to a high level of satisfaction, which is probably a main basic condition when meeting seriously ill children.

Purpose: To determine the impact of patient age, comorbidity, and physician factors on treatment recommendations for locally advanced, unresectable non-small-cell lung cancer (NSCLC). Methods and Materials: We surveyed radiation oncologists regarding their recommendations for treatment (chemoradiation, radiation alone, chemotherapy alone, or no therapy) for hypothetical patients with Stage IIIB NSCLC who varied by age (55 vs. 80 years) and comorbid illness (none, moderate, or severe chronic obstructive pulmonary disease [COPD]). Multinomial logistic regression was used to assess the impact of physician and practice characteristics on radiation oncologists' treatment recommendations for three scenarios with the least agreement. Results: Of 214 radiationmore » oncologists, nearly all (99%) recommended chemoradiation for a healthy 55 year old. However, there was substantial variability in recommendations for a 55 year old with severe COPD, an 80-year-old with moderate COPD, and an 80-year-old with severe COPD. Physicians seeing a lower volume of lung cancer patients were statistically less likely to recommend radiotherapy for younger or older patients with severe COPD (both p < 0.05), but the impact was modest. Conclusions: Nearly all radiation oncologists report following the evidence-based recommendation of chemoradiation for young, otherwise healthy patients with locally advanced, unresectable NSCLC, but there is substantial variability in treatment recommendations for older or sicker patients, probably related to the lack of clinical trial data for such patients. The physician and practice characteristics we examined only weakly affected treatment recommendations. Additional clinical trial data are necessary to guide recommendations for treatment of elderly patients and patients with poor pulmonary function to optimize their management.« less

The original 18-item, four-dimensional Trust in Oncologist Scale assesses cancer patients' trust in their oncologist. The current aim was to develop and validate a short form version of the scale to enable more efficient assessment of cancer patients' trust. Existing validation data of the full-length Trust in Oncologist Scale were used to create a short form of the Trust in Oncologist Scale. The resulting short form was validated in a new sample of cancer patients (n = 92). Socio-demographics, medical characteristics, trust in the oncologist, satisfaction with communication, trust in healthcare, willingness to recommend the oncologist to others and to contact the oncologist in case of questions were assessed. Internal consistency, reliability, convergent and structural validity were tested. The five-item Trust in Oncologist Scale Short Form was created by selecting the statistically best performing item from each dimension of the original scale, to ensure content validity. Mean trust in the oncologist was high in the validation sample (response rate 86%, M = 4.30, SD = 0.98). Exploratory factor analyses supported one-dimensionality of the short form. Internal consistency was high, and temporal stability was moderate. Initial convergent validity was suggested by moderate correlations between trust scores with associated constructs. The Trust in Oncologist Scale Short Form appears to efficiently, reliably and validly measures cancer patients' trust in their oncologist. It may be used in research and as a quality indicator in clinical practice. More thorough validation of the scale is recommended to confirm this initial evidence of its validity.

MO-D-BRF-01: Pediatric Treatment Planning II: The PENTEC Report On Normal Tissue Complications

DOE Office of Scientific and Technical Information (OSTI.GOV)

Constine, L; Hodgson, D; Bentzen, S

With advances in multimodality therapy, childhood cancer cure rates approach 80%. However, both radiotherapy and chemotherapy may cause debilitating or even fatal ‘late effects’ that are critical to understand, mitigate, or prevent. QUANTEC identified the uncertainties relating to side-effects of adult treatments, but this is more complicated for children in whom a mosaic of tissues develops at different rates and temporal sequences. Childhood cancer survivors have long life expectancy and may develop treatmentinduced secondary cancers and severe organ/tissue injury decades after treatment. Collaborative long-term observational studies and clinical research programs for survivors of pediatric and adolescent cancer provide some dose-responsemore » data for follow-up periods exceeding 40 years. Data analysis is challenging due to the influence of both therapeutic and developmental variables. PENTEC is a group of radiation oncologists, pediatric oncologists, subsepcialty physicians, medical physicists, biomathematic modelers/statisticians, and epidemiologists charged with conducting a critical synthesis of existing literature aiming to: critically analyze radiation dose-volume effects on normal tissue tolerances as a function of age/development in pediatric cancer patients in order to inform treatment planning and improve outcomes for survivors; describe relevant physics issues specific to pediatric radiotherapy; propose dose-volumeoutcome reporting standards to improve the knowledge base to inform future treatment guidelines. PENTEC has developed guidelines for systematic literature reviews, data extraction tolls and data analysis. This education session will discuss:1. Special considerations for normal tissue radiation response of children/adolescents, e.g. the interplay between development and radiotherapy effects.2. Epidemiology of organ/tissue injuries and secondary cancers.3. Exploration of dose-response differences between children and adults4. Methodology for literature review, data mining of outcomes databases, and NTCP or longitudinal modeling of doseresponse. 5. PENTEC goals and timetable. Learning Objectives: Understand important differences between normal tissue effects of radiation therapy in pediatric and adult patients. Be able to identify situations where there is ‘interplay’ between organ development and radiation-induced complications. Identify methods to systematically extract quantitative dose-volumeresponse relationships from existing outcomes databases. Provide guidance for the medical physicist to properly understand, implement, guide and control contemporary technology and applications in pediatric radiation oncology.« less

Musculoskeletal Injuries Affecting Radiologists According to the 2017 ACR Human Resources Commission Workforce Survey.

Practice leaders surveyed in the 2017 ACR Human Resources Commission workforce survey reported that 25% of the radiologists or radiation oncologists they supervised had neck pain, 32% had low back pain, and 16% were dealing with a repetitive stress injury. The prevalence rates of these musculoskeletal ailments among radiologists and radiation oncologists were consistent with those reported in the literature in other populations. However, these prevalence rates may be underestimated because practice leaders, not the radiologists themselves, were surveyed, and the leaders may not be aware of all injuries.

Chemoradiotherapy is the treatment mostly used as organ preservation (OP) strategy worldwide in advanced laryngo-hypopharyngeal cancer. Due to the not homogeneous results of the literature data regarding the pre-treatment assessment and treatment schedule in this setting of patients, the Italian societies of radiation oncology and medical oncology surveyed (by an online survey) their memberships regarding the Italian attitude on larynx preservation in clinical practice. The survey outline addressed different items such as: demographics (11 items), pre-treatment evaluation (12 items), treatment schedules (10 items) and outcomes (3 items). The survey was filled in by 116 clinical oncologists (64 % radiation and 36 % medical oncologists). Results highlighted that pretreatment evaluation was not homogeneous among the respondents. The treatment of choice for the OP program resulted the concurrent chemoradiotherapy (66 %). Induction chemotherapy was proposed mostly in case of aggressive tumors such as advanced stage (T4 or N3) and/or unfavorable primary sites (hypopharynx). Moreover, after induction chemotherapy, for responders patients most participants (46 %) proposed concurrent chemoradiotherapy, while 18 and 19 % proposed radiotherapy alone or radiotherapy and cetuximab, respectively. For patients with stable disease after induction chemotherapy, the respondents declared to suggest surgery, radiotherapy and cetuximab or radiotherapy alone in 38, 32 and 15 % of cases, respectively. Results of the present survey highlighted the variability of therapeutic approaches offered in clinical practice for patients candidate to a larynx OP program. Analysis of abovementioned results may give the chance to modify some clinical attitudes and create the background for future clinical investigation in this field.

Purpose: There has been little radiation oncologist (RO)-specific research in continuing medical education (CME) or quality improvement (QI) program efficacy. Our aim was to evaluate a CME/QI program for changes in RO behavior, performance, and adherence to department protocols/studies over the first 12 months of the program. Methods and Materials: The CME/QI program combined chart audit with feedback (C-AWF), simulation review AWF (SR-AWF), reminder checklists, and targeted CME tutorials. Between April 2003 and March 2004, management of 75 patients was evaluated by chart audit with feedback (C-AWF) and 178 patients via simulation review audit (SR-AWF) using a validated instrument. Scoresmore » were presented, and case management was discussed with individualized educational feedback. RO behavior and performance was compared over the first year of the program. Results: Comparing the first and second 6 months, there was a significant improvement in mean behavior (12.7-13.6 of 14, p = 0.0005) and RO performance (7.6-7.9 of 8, p = 0.018) scores. Protocol/study adherence significantly improved from 90.3% to 96.6% (p = 0.005). A total of 50 actions were generated, including the identification of learning needs to direct CME tutorials, the systematic change of suboptimal RO practice, and the alteration of deficient management of 3% of patients audited during the program. Conclusion: An integrated CME/QI program combining C-AWF, SR-AWF, QI reminders, and targeted CME tutorials effectively improved targeted RO behavior and performance over a 12-month period. There was a corresponding increase in departmental protocol and study adherence.« less

Supply and Demand for Radiation Oncology in the United States: Updated Projections for 2015 to 2025

DOE Office of Scientific and Technical Information (OSTI.GOV)

Pan, Hubert Y.; Haffty, Bruce G.; Falit, Benjamin P.

Purpose: Prior studies have forecasted demand for radiation therapy to grow 10 times faster than the supply between 2010 and 2020. We updated these projections for 2015 to 2025 to determine whether this imbalance persists and to assess the accuracy of prior projections. Methods and Materials: The demand for radiation therapy between 2015 and 2025 was estimated by combining current radiation utilization rates determined by the Surveillance, Epidemiology, and End Results data with population projections provided by the US Census Bureau. The supply of radiation oncologists was forecast by using workforce demographics and full-time equivalent (FTE) status provided by themore » American Society for Radiation Oncology (ASTRO), current resident class sizes, and expected survival per life tables from the US Centers for Disease Control. Results: Between 2015 and 2025, the annual total number of patients receiving radiation therapy during their initial treatment course is expected to increase by 19%, from 490,000 to 580,000. Assuming a graduating resident class size of 200, the number of FTE physicians is expected to increase by 27%, from 3903 to 4965. In comparison with prior projections, the new projected demand for radiation therapy in 2020 dropped by 24,000 cases (a 4% relative decline). This decrease is attributable to an overall reduction in the use of radiation to treat cancer, from 28% of all newly diagnosed cancers in the prior projections down to 26% for the new projections. By contrast, the new projected supply of radiation oncologists in 2020 increased by 275 FTEs in comparison with the prior projection for 2020 (a 7% relative increase), attributable to rising residency class sizes. Conclusion: The supply of radiation oncologists is expected to grow more quickly than the demand for radiation therapy from 2015 to 2025. Further research is needed to determine whether this is an appropriate correction or will result in excess capacity.« less

Human papillomavirus (HPV) associated head and neck squamous cell cancers (HNSCC) have become increasingly common in the West, but the same cannot be said about India. These cancers have a different biology and confer a better prognosis, however, its current role in the management of patients in India is not clearly defined. At the 35 th Indian Cooperative Oncology Network conference held in September 2016, a panel of radiation, surgical and medical oncologists, pathologists, and basic scientists from across the country having experience in clinical research with respect to HPV in HNSCC reviewed the available literature from India. All the ideas and facts were thereafter collated in this report. Various topics of controversy in dealing with the diagnosis and management of HPV-associated HNSCC have been highlighted in this report in context to the Indian scenario. Furthermore, the prevalence of the same and its association with tobacco and high-risk sexual behavior has been touched on. Conclusively, a set of recommendations has been proposed by the panel to guide the practicing oncologists of the country while dealing with HPV-associated HNSCC.

The burden of advanced basal cell carcinoma (aBCC) is not fully understood. To compare BCC disease burden and treatment patterns for aBCC with those for non-aBCC. A retrospective, insurance claims-based study design was used. Adults with ≥2 claims associated with a BCC diagnosis (ICD-9-CM 173.x1) separated by ≥30 days on or after October 1, 2011, were classified as aBCC or non-aBCC by using an algorithm based on metastasis diagnosis, radiation therapy use, and medical oncologist/other specialist use. Non-aBCC and aBCC patients were matched 1:1 on the basis of age, sex, and region, and assigned the same index date (date of first qualifying diagnosis or event). Comparisons were made using Wilcoxon signed-rank (continuous variables) and McNemar's (categorical variables) tests. In total, 847 matched aBCC/non-aBCC patient pairs were selected (mean age 75 years; 57% men; locally advanced BCC, n = 826; metastatic BCC, n = 21). During the 12-month study period following the index date, aBCC patients had a significantly higher mean Charlson Comorbidity Index (P = .0023), significantly higher mean numbers of outpatient/dermatologist/medical oncologist visits (all P < .0001), and significantly higher mean total/medical/inpatient/outpatient/BCC treatment costs (all P < .05). This study only included information from a database on commercial insurance and Medicare claims. The algorithm criteria might have restricted patient numbers; data were not fully reflective of targeted therapy era. aBCC patients had a higher disease burden than non-aBCC patients. Cost differences were largely driven by higher BCC treatment costs, specifically radiation therapy. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

In technically advanced multicentre clinical trials, participating centres can benefit from a credentialing programme before participating in the trial. Education of staff in participating centres is an important aspect of a successful clinical trial. In the multicentre study of fractionated versus single fraction stereotactic ablative body radiotherapy in lung oligometastases (TROG 13.01), knowledge transfer of stereotactic ablative body radiotherapy techniques to the local multidisciplinary team is intended as part of the credentialing process. In this study, a web-based learning platform was developed to provide education and training for the multidisciplinary trial teams at geographically distinct sites. A web-based platform using eLearning software consisting of seven training modules was developed. These modules were based on extracranial stereotactic theory covering the following discrete modules: Clinical background; Planning technique and evaluation; Planning optimisation; Four-dimensional computed tomography simulation; Patient-specific quality assurance; Cone beam computed tomography and image guidance; Contouring organs at risk. Radiation oncologists, medical physicists and radiation therapists from hospitals in Australia and New Zealand were invited to participate in this study. Each discipline was enrolled into a subset of modules (core modules) and was evaluated before and after completing each module. The effectiveness of the eLearning training will be evaluated based on (i) knowledge retention after participation in the web-based training and (ii) confidence evaluation after participation in the training. Evaluation consisted of a knowledge test and confidence evaluation using a Likert scale. In total, 130 participants were enrolled into the eLearning programme: 81 radiation therapists (62.3%), 27 medical physicists (20.8%) and 22 radiation oncologists (16.9%). There was an average absolute improvement of 14% in test score (P < 0.001) after learning. This score improvement compared with initial testing was also observed in the long-term testing (>4 weeks) after completing the modules (P < 0.001). For most there was significant increase in confidence (P < 0.001) after completing all the modules. Copyright © 2016 The Royal College of Radiologists. Published by Elsevier Ltd.

2012-03-15

Purpose: Statistics from the Canadian post-MD education registry show that numbers of Canadian radiation oncology (RO) trainees have risen from 62 in 1999 to approximately 150 per year between 2003 and 2009, contributing to the current perceived downturn in employment opportunities for radiation oncologists in Canada. When last surveyed in 2003, Canadian RO residents identified job availability as their main concern. Our objective was to survey current Canadian RO residents on their training and career plans. Methods and Materials: Trainees from the 13 Canadian residency programs using the national matching service were sought. Potential respondents were identified through individual programmore » directors or chief resident and were e-mailed a secure link to an online survey. Descriptive statistics were used to report responses. Results: The eligible response rate was 53% (83/156). Similar to the 2003 survey, respondents generally expressed high satisfaction with their programs and specialty. The most frequently expressed perceived weakness in their training differed from 2003, with 46.5% of current respondents feeling unprepared to enter the job market. 72% plan on pursuing a postresidency fellowship. Most respondents intend to practice in Canada. Fewer than 20% of respondents believe that there is a strong demand for radiation oncologists in Canada. Conclusions: Respondents to the current survey expressed significant satisfaction with their career choice and training program. However, differences exist compared with the 2003 survey, including the current perceived lack of demand for radiation oncologists in Canada.« less

TU-H-CAMPUS-JeP2-03: Machine-Learning-Based Delineation Framework of GTV Regions of Solid and Ground Glass Opacity Lung Tumors at Datasets of Planning CT and PET/CT Images

Ikushima, K; Arimura, H; Jin, Z

Purpose: In radiation treatment planning, delineation of gross tumor volume (GTV) is very important, because the GTVs affect the accuracies of radiation therapy procedure. To assist radiation oncologists in the delineation of GTV regions while treatment planning for lung cancer, we have proposed a machine-learning-based delineation framework of GTV regions of solid and ground glass opacity (GGO) lung tumors following by optimum contour selection (OCS) method. Methods: Our basic idea was to feed voxel-based image features around GTV contours determined by radiation oncologists into a machine learning classifier in the training step, after which the classifier produced the degree ofmore » GTV for each voxel in the testing step. Ten data sets of planning CT and PET/CT images were selected for this study. The support vector machine (SVM), which learned voxel-based features which include voxel value and magnitudes of image gradient vector that obtained from each voxel in the planning CT and PET/CT images, extracted initial GTV regions. The final GTV regions were determined using the OCS method that was able to select a global optimum object contour based on multiple active delineations with a level set method around the GTV. To evaluate the results of proposed framework for ten cases (solid:6, GGO:4), we used the three-dimensional Dice similarity coefficient (DSC), which denoted the degree of region similarity between the GTVs delineated by radiation oncologists and the proposed framework. Results: The proposed method achieved an average three-dimensional DSC of 0.81 for ten lung cancer patients, while a standardized uptake value-based method segmented GTV regions with the DSC of 0.43. The average DSCs for solid and GGO were 0.84 and 0.76, respectively, obtained by the proposed framework. Conclusion: The proposed framework with the support vector machine may be useful for assisting radiation oncologists in delineating solid and GGO lung tumors.« less

The planning of irradiation treatments is a task of medical physics, based on the appropriate calculations of a dose distribution from radiation beams, virtually set up on a simulation software. This task is at the centre of the chain of treatment preparation: between the contouring phase and the objective definition, which are specialties of the radiation oncologist, and the joint validation of the treatment plan by the physician and the physicist. Historically, this task has been performed by the medical physicist, but can be delegated to other professionals, especially radiation technologists. The evolution of the techniques and procedures tends to a specialization of the skilled workers toward this new work of dosimetry specialist or treatment planning technician. In this paper, the training, relational and organizational aspects will be described to explain how the delegation of the tasks, in the context of treatment plan preparation between professionals can be set up with the highest level of quality and security for the patient treatment and with the respect of legal obligations and requirements of each profession.

A sophisticated understanding of the rapidly changing field of oncology, including a broad knowledge of oncologic disease and the therapies available to treat them, is fundamental to the interventional radiologist providing oncologic therapies, and is necessary to affirm interventional oncology as one of the four pillars of cancer care alongside medical, surgical, and radiation oncology. The first part of this review intends to provide a concise overview of the fundamentals of oncologic clinical trials, including trial design, methods to assess therapeutic response, common statistical analyses, and the levels of evidence provided by clinical trials.

Cancer Care Ontario implemented synoptic pathology reporting across Ontario, impacting the practice of pathologists, surgeons, and medical and radiation oncologists. The benefits of standardized synoptic pathology reporting include enhanced completeness and improved consistency in comparison with narrative reports, with reported challenges including increased workload and report turnaround time. To determine the impact of synoptic pathology reporting on physician satisfaction specific to practice and process. A descriptive, cross-sectional design was utilized involving 970 clinicians across 27 hospitals. An 11-item survey was developed to obtain information regarding timeliness, completeness, clarity, and usability. Open-ended questions were also employed to obtain qualitative comments. A 51% response rate was obtained, with descriptive statistics reporting that physicians perceive synoptic reports as significantly better than narrative reports. Correlation analysis revealed a moderately strong, positive relationship between respondents' perceptions of overall satisfaction with the level of information provided and perceptions of completeness for clinical decision making (r = 0.750, P < .001) and ease of finding information for clinical decision making (r = 0.663, P < .001). Dependent t tests showed a statistically significant difference in the satisfaction scores of pathologists and oncologists (t169 = 3.044, P = .003). Qualitative comments revealed technology-related issues as the most frequently cited factor impacting timeliness of report completion. This study provides evidence of strong physician satisfaction with synoptic cancer pathology reporting as a clinical decision support tool in the diagnosis, prognosis, and treatment of cancer patients.

Oncologists have a critical opportunity to utilize risk assessment and cancer prevention strategies to interrupt the initiation or progression of cancer in cancer survivors and individuals at high risk of developing cancer. Expanding knowledge about the natural history and prognosis of cancers positions oncologists to advise patients regarding the risk of second malignancies and treatment-related cancers. In addition, as recognized experts in the full spectrum of cancer care, oncologists are afforded opportunities for involvement in community-based cancer prevention activities. Although oncologists are currently providing many cancer prevention and risk assessment services to their patients, economic barriers exist, including inadequate or lack of insurance, that may compromise uniform patient access to these services. Additionally, insufficient reimbursement for existing and developing interventions may discourage patient access to these services. The American Society of Clinical Oncology (ASCO), the medical society representing cancer specialists involved in patient care and clinical research, is committed to supporting oncologists in their wide-ranging involvement in cancer prevention. This statement on risk assessment and prevention counseling, although not intended to be a comprehensive overview of cancer prevention describes the current role of oncologists in risk assessment and prevention; provides examples of risk assessment and prevention activities that should be offered by oncologists; identifies potential opportunities for coordination between oncologists and primary care physicians in prevention education and coordination of care for cancer survivors; describes ASCO's involvement in education and training of oncologists regarding prevention; and proposes improvement in the payment environment to encourage patient access to these services.

African Americans are consistently underrepresented in cancer clinical trials. Minority under-enrolment may be, in part, due to differences in the way clinical trials are discussed in oncology visits with African American vs. White patients. To investigate differences in oncologist-patient communication during offers to participate in clinical trials in oncology visits with African American and White patients. From an archive of video-recorded oncology visits, we selected all visits with African American patients that included a trial offer (n = 11) and a matched sample of visits with demographically/medically comparable White patients (n = 11). Using mixed qualitative-quantitative methods, we assessed differences by patient race in (i) word count of entire visits and (ii) frequency of mentions and word count of discussions of clinical trials and key elements of consent. Visits with African American patients, compared to visits with White patients, were shorter overall and included fewer mentions of and less discussion of clinical trials. Also, visits with African Americans included less discussion of the purpose and risks of trials offered, but more discussion of voluntary participation. African American patients may make decisions about clinical trial participation based on less discussion with oncologists than do White patients. Possible explanations include a less active communication style of African Americans in medical visits, oncologists' concerns about patient mistrust, and/or oncologist racial bias. Findings suggest oncologists should pay more conscious attention to developing the topic of clinical trials with African American patients, particularly purpose and risks. © 2013 John Wiley & Sons Ltd.

Objective Little is known about the nature of psychosocial care delivered by oncologists. The goal of this study was to survey oncologists about their management of psychosocial distress, referencing the National Comprehensive Cancer Network guidelines. Methods A random sample of 1,000 oncologists were sent an e-mail requesting their participation in an online survey; nonrespondents were sent the survey through postal mail. Regression analyses were conducted to identify independent predictors of care. Results Forty-six percent (448 of 965) of oncologists responded. Practice locations included: community (63%), cancer center (25%), and hospital (7%). Respondents estimated that over one-third of their patients (mean± SD=38%±22%) experience psychosocial distress warranting intervention, although only 225 of 447 (50%) indicated having mental health services affiliated with their practice. Nearly half (212 of 447, 47%) reported only initiating a referral for psychosocial services, and 214 of 447 (48%) reported both making a referral and starting psychiatric medications, mainly selective serotonin reuptake inhibitors and benzodiazepines. Conclusions Most oncologists delivered some level of psychosocial care, although only half had affiliated mental health services. PMID:19648204

The delegation of the on board imaging position control, from the radiation oncologist to the therapist, is justified by the generalization of the image-guided radiotherapy techniques which are particularly time consuming. This delegation is however partial. Indeed, the validation of the position by the therapist can be clearly performed when the registration is based on bony landmark or fiducial. The radiation oncologist needs however to make the validation in case of large target displacement, in more complex soft tissue-based registration, and in case of stereotactic body radiation therapy. Moreover, this delegation implies at least three conditions which are first the training of the staff, then the formalization of the procedures, responsibilities and delegations and finally, the evaluation of the practices of IGRT.

Background Medical oncology is a steadily evolving field of medical practice and professional pathway for doctors, offering value, opportunity and challenge to those who chose this medical specialty. This study examines the experiences of a group of Australian medical oncologists, with an emphasis on their professional practice, career experiences, and existing and emerging challenges across career stages. Methods In-depth qualitative interviews were conducted with 22 medical oncologists, including advanced trainees, early-career consultants and senior consultants, focusing on: professional values and experiences; career prospects and pathways; and, the nexus of the characteristics of the profession and delivery of care. Results The following themes were emergent from the interviews: the need for professional reinvention and the pressure to perform; the importance, and often absence, of mentoring and feedback loops; the emotional labour of oncology; and, the impact of cascading workload volume on practice sustainability. Conclusions Understanding professional experiences, career trajectories and challenges at the workforce level are crucial for understanding what drives the oncological care day-to-day. The results indicate that there are considerable potential tensions between the realities of professional, workforce demands and expectations for patient care. Such tensions have real and significant consequences on individual medical oncologists with respect to their futures, aspirations, satisfaction with work, caring practices, interactions with patients and potentially therapeutic outcomes.

2003-06-01

Radiation oncologists frequently engage in activities that involve the collection and analysis of data from medical records. Access to health information is an ethical issue because, if not done according to appropriate guidelines, it constitutes an invasion of privacy or breach in confidentiality. To protect patients for the social harm that may result from medical record review, our society has established laws and regulations that apply to projects that require medical record review. A major branch point in the guidelines for such projects is whether private information will be collected for research or nonresearch purposes. However, a problem with discussing privacy protection in terms of a research versus nonresearch model is that it is difficult to make this distinction for many kinds of projects. The purpose of this paper is to establish a practical guideline that can be used to decide if a project that involves analysis of private, identifiable medical information should be considered research from the regulatory standpoint.

Diagnosis and treatment of bone metastasis requires various types of measures, specialists and caregivers. To provide better diagnosis and treatment, a multidisciplinary team approach is required. The members of this multidisciplinary team include doctors of primary cancers, radiologists, pathologists, orthopaedists, radiotherapists, clinical oncologists, palliative caregivers, rehabilitation doctors, dentists, nurses, pharmacists, physical therapists, occupational therapists, medical social workers, etc. Medical evidence was extracted from published articles describing meta-analyses or randomised controlled trials concerning patients with bone metastases mainly from 2003 to 2013, and a guideline was developed according to the Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Multidisciplinary team meetings are helpful in diagnosis and treatment. Clinical benefits such as physical or psychological palliation obtained using the multidisciplinary team approaches are apparent. We established a guideline describing each specialty field, to improve understanding of the different fields among the specialists, who can further provide appropriate treatment, and to improve patients' outcomes.

Communication during racially-discordant interactions is often of poor quality and may contribute to racial treatment disparities. We evaluated an intervention designed to increase patient active participation and other communication-related outcomes during interactions between Black patients and non-Black oncologists. Participants were 18 non-Black medical oncologists and 114 Black patients at two cancer hospitals in Detroit, Michigan, USA. Before a clinic visit to discuss treatment, patients were randomly assigned to usual care or to one of two question prompt list (QPL) formats: booklet (QPL-Only), or booklet and communication coach (QPL-plus-Coach). Patient-oncologist interactions were video recorded. Patients reported perceptions of the intervention, oncologist communication, role in treatment decisions, and trust in the oncologist. Observers assessed interaction length, patient active participation, and oncologist communication. The intervention was viewed positively and did not increase interaction length. The QPL-only format increased patient active participation; the QPL-plus-Coach format decreased patient perceptions of oncologist communication. No other significant effects were found. This QPL booklet is acceptable and increases patient active participation in racially-discordant oncology interactions. Future research should investigate whether adding physician-focused interventions might improve other outcomes. This QPL booklet is acceptable and can improve patient active participation in racially-discordant oncology interactions. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Recent advances in the medical treatment of Cushing’s disease

PubMed Central

2014-01-01

Cushing’s disease is a condition of hypercortisolism caused by an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma. While rare, it is associated with significant morbidity and mortality, which suggests that early and aggressive intervention is required. The primary, definitive therapy for patients with Cushing’s disease in the majority of patients is pituitary surgery, generally performed via a transsphenoidal approach. However, many patients will not achieve remission or they will have recurrences. The consequences of persistent hypercortisolism are severe and, as such, early identification of those patients at risk of treatment failure is exigent. Medical management of Cushing’s disease patients plays an important role in achieving long-term remission after failed transsphenoidal surgery, while awaiting effects of radiation or before surgery to decrease the hypercortisolemia and potentially reducing perioperative complications and improving outcome. Medical therapies include centrally acting agents, adrenal steroidogenesis inhibitors and glucocorticoid receptor blockers. Furthermore, several new agents are in clinical trials. To normalize the devastating disease effects of hypercortisolemia, it is paramount that successful patient disease management includes individualized, multidisciplinary care, with close collaboration between endocrinologists, neurosurgeons, radiation oncologists, and general surgeons. This commentary will focus on recent advances in the medical treatment of Cushing’s, with a focus on newly approved ACTH modulators and glucocorticoid receptor blockers. PMID:24669299

Burnout is a serious problem facing the majority of oncologists. Many medical students may regard oncology as depressive part of medicine. This false picture may discourage them from choosing oncology as their future specialization. To learn problems experienced by oncologists and to answer the students' question: is it dangerous to choose oncology? We conducted an anonymous survey among 69 oncologists. Young doctors (up to 5 years of service) accounted for 31 %, specialists 69 %, with a median length of practice of 14 years. The most frequently reported symptoms included irritability (84 %) and tension (74 %). Forty-five percent reported headaches, 25 % sleep disorders, 51 % negative impact on their personal lives. Excessive bureaucratization, overwork, and haste, with the disparity between undertaken effort and compensation were the most common sources of stress. Stress reduction methods were as follows: their relationship with family and/or friends (69 %), reading books/watching movies (66 %), emotional distance from their problems (63 %), and contact with nature (62 %). Ninety-six percent of physicians were satisfied with their choice of pursuing work with cancer patients. However, as many as 49 % of oncologists experienced moments of doubt regarding their sense of vocation. Students and young doctors considering pursuing an oncological speciality should not be discouraged by the likely degree of sacrifice or burden, but rather aim to develop effective ways to reduce stress, along with remembering one's own health needs. This could be valuable part of both pregradual and postgradual medical education, worth to become part of medical curricula.

Picture Archiving And Communications Systems (PACS) And Radiation Therapy Planning: Data And Workstation Requirements

1986-06-01

PACS literature to date has emphasized the needs of diagnostic imaging; however, the ability to acquire, manipulate, and display data derived from multiple imaging modalities is also vital in the practice of radiation oncology and radiation therapy planning (RTP). Radiographic or scintigraphic images for RTP must include specific spatial calibration data, as well as data relating image acquisition to anatomic localization within the patient. The digital nature of PACS images and displays allows the radiation oncologist to interactively assist in evaluating whether or not near-by structures are tumor-free. The radiation oncologist may also need to review nonradiographic diagnostic images (e.g., endoscopic images or pathology tissue specimens). Finally, it must be possible to take data such as isodose lines and superimpose them onto images relating the proposed therapy field to patient anatomy. Not only would this be useful for the radiation oncologist, but it would also provide information currently not easily available to the diagnostician and useful in subsequent diagnostic efforts. The three-dimensional (volumetric) data creation for RTP is not currently widespread because of the difficulties in converting images into a coherent, reliable and registered data set; this is the unique contribution of PACS. Software must be developed to permit creation of volumetric models based on data derived from both planar images and various tomographic modalities, including calibration and localizaton data for accurate image registration and scaling. This will permit positive definition of tumor volume by diagnosticians and the radiation oncologists as an initial portion of the therapy planning process. As a part of the underlying data structure for such systems, there must be some uniformity of image format between modalities and vendors; this has been adequately addressed by the Digital Imaging and Communications Interface Standard recently adopted by the American College of Radiology and the National Electrical Manufacturers' Association (ACR-NEMA). In addition, such standardization efforts must also incorporate the necessary calibration and coordinate data. This paper will examine some of the unique requirements for PACS (and PACS workstations)optimized for RTP. The assumption is made here that these are not independent, self-sufficient devices; rather, they are subsystems of a PACS network, capable of sharing certain resources.

Quality control is of special importance in head and neck oncology since the quality of medical care constitutes a vital parameter for the diseased patient. In contrast to other medical specialties, no quality assurance program for head and neck cancer patients has yet been established in Germany. Therefore, a survey was conducted to assess the quality assurance instruments that are in use today in otorhinolaryngology-head and neck (ORL-HNS) centers. In a nationwide survey, questionnaires were sent out to 146 German ORL-HNS departments (the return rate was 75%). 56% of all departments apply dedicated quality assurance processes, and 38% have appointed a formal quality assurance officer. Interdisciplinary oncological conferences are held in the vast majority of all departments with the participation of radiation oncologists in 86 (78%), medical oncologists in 84 (76%), diagnostic radiologists in 82 (74%), and pathologists in 73 (66%). Morbidity-mortality conferences are held in seven departments (6%). A standardized follow-up of oncological patients is carried out in 95 units (86%), and 53 departments use computer-assisted data bases to organize their follow-up data (48%). A wide variety of documentation systems is in use throughout the country: 78 units (71%) offer formal follow-up to their oncological patients. This survey documents a wide-spread interest in quality assurance procedures. Many individual efforts are being undertaken. However, no uniform quality assurance or auditing system is currently in use in Germany nor is a commonly accepted data base available. The ability to offer oncological follow-up within the national social security system is generally considered indispensable for the maintenance of high-quality oncological care in ORL-HNS departments.

Specialist oncology pharmacists are being trained in Japan to assist cancer treatment teams. These specialized pharmacists address patients' physical and mental problems in pharmacist-managed cancer care clinics, actively participate in formulating treatment policies, and are beneficial in offering qualitative improvements to patient services and team medical care. However, the effect of outpatient treatment by oncology pharmacists on therapeutic outcomes and medical costs is still unknown. A retroactive comparative analysis of the treatment details and clinical course was conducted among three groups of patients: patients who underwent adjuvant chemotherapy managed by a gynecologic oncologist only (S arm), patients managed by a non-oncologist (general practice gynecologist) only (NS arm), and patients managed by both a non-oncologist and a specialist oncology pharmacist (NS+Ph arm). The medical cost per course was significantly lower for patients in the NS+Ph arm than for those in the other two arms. Surprisingly, the outpatient treatment rate in the NS+Ph arm was overwhelmingly high. The involvement of an oncology pharmacist did not make a significant difference in therapeutic outcomes such as recurrence rate and survival. The participation of oncology pharmacists in the management of cancer patients undergoing chemotherapy enables safe outpatient treatment and also reduces medical costs.

There has been increasing scrutiny about cancer treatment for patients very near the end of life (EoL), yet a substantial number receive palliative radiation therapy (RT) in this setting. Our aim was to document the attitudes and intentions of thought leaders and trainees in giving RT near the EoL. We distributed an anonymous survey to 473 radiation oncologists and residents. The survey examined the clinical and psychosocial factors considered as well as intentions and expectations in the delivery of RT near the EoL. Factors surrounding unfinished treatment courses, and the formative factors that shape opinions about RT at the EoL were also explored. We received 139 responses (29%). Eighty-nine percent of respondents worked at academic institutions. The factors that respondents most often consider very or extremely important to offer RT near the EoL were the preference of the patient to be treated (94%), the ability to tolerate treatment (88%), and palliative intent (70%). After instances when their patients were unable to complete treatment near the EoL, 42% of respondents said they would prescribe a shorter treatment the next time they see a similar patient. Personal experience (71%) was most often listed as very or extremely important in shaping their opinions about RT near the EoL. Survey respondents, 89% of whom were academic radiation oncologists, have a positive view of palliative RT near the EoL. They favor shorter fractionation for patients near the EoL. Personal experience is most important in shaping practices and attitudes.

SU-G-201-09: Evaluation of a Novel Machine-Learning Algorithm for Permanent Prostate Brachytherapy Treatment Planning

Purpose: A novel, automated, algorithm for permanent prostate brachytherapy (PPB) treatment planning has been developed. The novel approach uses machine-learning (ML), a form of artificial intelligence, to substantially decrease planning time while simultaneously retaining the clinical intuition of plans created by radiation oncologists. This study seeks to compare the ML algorithm against expert-planned PPB plans to evaluate the equivalency of dosimetric and clinical plan quality. Methods: Plan features were computed from historical high-quality PPB treatments (N = 100) and stored in a relational database (RDB). The ML algorithm matched new PPB features to a highly similar case in the RDB;more » this initial plan configuration was then further optimized using a stochastic search algorithm. PPB pre-plans (N = 30) generated using the ML algorithm were compared to plan variants created by an expert dosimetrist (RT), and radiation oncologist (MD). Planning time and pre-plan dosimetry were evaluated using a one-way Student’s t-test and ANOVA, respectively (significance level = 0.05). Clinical implant quality was evaluated by expert PPB radiation oncologists as part of a qualitative study. Results: Average planning time was 0.44 ± 0.42 min compared to 17.88 ± 8.76 min for the ML algorithm and RT, respectively, a significant advantage [t(9), p = 0.01]. A post-hoc ANOVA [F(2,87) = 6.59, p = 0.002] using Tukey-Kramer criteria showed a significantly lower mean prostate V150% for the ML plans (52.9%) compared to the RT (57.3%), and MD (56.2%) plans. Preliminary qualitative study results indicate comparable clinical implant quality between RT and ML plans with a trend towards preference for ML plans. Conclusion: PPB pre-treatment plans highly comparable to those of an expert radiation oncologist can be created using a novel ML planning model. The use of an ML-based planning approach is expected to translate into improved PPB accessibility and plan uniformity.« less

Well-trained and highly motivated future generations of multidisciplinary oncologists are essential to ensure the optimal evolution of the field of oncology with the ultimate goal of providing the best possible care to patients with cancer. ESMO's career development portfolio is managed and continuously optimised by several dedicated committees composed of ESMO officers and is directly supervised by the ESMO Executive Board and the ESMO President. It offers unique resources for YOs at all stages of training and includes a broad variety of fellowship opportunities, educational courses, scientific meetings, publications and resources. In this article, we provide an overview of the activities and career development opportunities provided by ESMO to the next generation of oncologists. PMID:28255451

Three-dimensional conformal radiation therapy requires the precise definition of the target volume. Its potential benefits could be offset by the inconsistency in target definition by radiation oncologists. In a previous survey of radiation oncologists, a large degree of variation in target volume definition of cervical esophageal cancer was noted for the boost phase of radiotherapy. The present study evaluated whether special training could improve the consistency in target volume definitions. A pre-training survey was performed to establish baseline values. This was followed by a special one-on-one training session on treatment planning based on the RTOG 94-05 protocol to 12 radiation oncologists. Target volumes were redrawn immediately and at 1-2 months later. Post-training vs. pre-training target volumes were compared. There was less variability in the longitudinal positions of the target volumes post-training compared to pre-training (p < 0.05 in 5 of 6 comparisons). One case had more variability due to the lack of a visible gross tumor on CT scans. Transverse contours of target volumes did not show any significant difference pre- or post-training. For cervical esophageal cancer, this study suggests that special training on protocol guidelines may improve consistency in target volume definition. Explicit protocol directions are required for situations where the gross tumor is not easily visible on CT scans. This may be particularly important for multicenter clinical trials, to reduce the occurrences of protocol violations.

The purpose of this survey was to define attitudes and opinions of two types of physicians, medical students and lawyers in the area of euthanasia and related issues and problems. A questionnaire was used as the source of data. There were four groups of test persons: oncologists, home care physicians (family doctors), third-year medical students and lawyers. The questionnaire included 22 questions, 4 of which concerned general characteristics of tested persons (including religious belief), while 18 referred to the problems of euthanasia. The total number of tested persons was 123, 55 men and 68 women with a median age of 38 +/- 11 years ( +/- SD). There were 30 test persons in the group of oncologists, 31 in the group of family doctors, 31 in the group of third-year students, and 31 in the group of lawyers. Between 97% and 100% of individuals gave scored responses to most items. More than half of the individuals (57%) were against euthanasia, and 61% are against the legalization of euthanasia. The views of doctors and medical students were similar (2/3 against) and significantly different from the view of lawyers (2/3 for, P < 0.01). The legalization of euthanasia is favored by 61% of lawyers, in contrast to 43%, 30% and 23% of oncologists, family doctors and medical students, respectively. Overall, 31% sais they would apply euthanasia if they were asked for it, and 36% that would if it had been legalized. Lawyers are twice as willing to perform euthanasia as students or physicians. The least ready to apply euthanasia are physicians working as oncologists (only 1 in 5). Compared with oncologists, one-third of home-care physicians would perform euthanasia anyway, whether legalized or not. Most of the test persons were of the opinion that euthanasia should be performed in the case of children born with a severe anomaly. None of the tested groups considered invalidity or being a burden to the family important reasons for the termination of somebody's life. Approximately 40% of responders believed that the decision for euthanasia should be made by the patient alone. Only lawyers were of the opinion that the misuse of euthanasia could be controlled. Our study shows that it is probably more important to determine factors associated with behavior pertaining to euthanasia in physicians working closely with suffering patients. Reducing suffering and launching a hospice movement and palliative care services might be the most appropriate way to deal with the problem of euthanasia.

The various image-guided radiotherapy techniques raise the question of how to achieve the control of patient positioning before irradiation session and sharing of tasks between radiation oncologists and radiotherapy technicians. We have put in place procedures and operating methods to make a partial delegation of tasks to radiotherapy technicians and secure the process in three situations: control by orthogonal kV imaging (kV-kV) of bony landmarks, control by kV-kV imaging of intraprostatic fiducial goldmarkers and control by cone beam CT (CBCT) imaging for prostate cancer. Significant medical overtime is required to control these three IGRT techniques. Because of their competence in imaging, these daily controls can be delegated to radiotherapy technicians. However, to secure the process, initial training and regular evaluation are essential. The analysis of the comparison of the use of kV/kV on bone structures allowed us to achieve a partial delegation of control to radiotherapy technicians. Controlling the positioning of the prostate through the use and automatic registration of fiducial goldmarkers allows better tracking of the prostate and can be easily delegated to radiotherapy technicians. The analysis of the use of daily cone beam CT for patients treated with intensity modulated irradiation is underway, and a comparison of practices between radiotherapy technicians and radiation oncologists is ongoing to know if a partial delegation of this control is possible.

The development of accelerators with on-board imaging systems now allows better target volumes reset at the time of irradiation (image-guided radiotherapy [IGRT]). However, these technological advances in the control of repositioning led to a multiplication of tasks for each actor in radiotherapy and increase the time available for the treatment, whether for radiotherapy technicians or radiation oncologists. As there is currently no explicit regulatory framework governing the use of IGRT, some institutional experiments show that a transfer is possible between radiation oncologists and radiotherapy technicians for on-line verification of image positioning. Initial training for every technical and drafting procedures within institutions will improve audit quality by reducing interindividual variability. Copyright © 2013. Published by Elsevier SAS.

Radiotherapy in patients with connective tissue diseases.

The decision to offer radiotherapy in patients with connective tissue diseases continues to be challenging. Radiotherapy might trigger the onset of connective tissue diseases by increasing the expression of self-antigens, diminishing regulatory T-cell activity, and activating effectors of innate immunity (dendritic cells) through Toll-like receptor-dependent mechanisms, all of which could potentially lead to breaks of immune tolerance. This potential risk has raised some debate among radiation oncologists about whether patients with connective tissue diseases can tolerate radiation as well as people without connective tissue diseases. Because the number of patients with cancer and connective tissue diseases needing radiotherapy will probably increase due to improvements in medical treatment and longer life expectancy, the issue of interactions between radiotherapy and connective tissue diseases needs to be clearer. In this Review, we discuss available data and evidence for patients with connective tissue diseases treated with radiotherapy. Copyright © 2016 Elsevier Ltd. All rights reserved.

Kurman, Jonathan S.

2018-01-01

Immunotherapy agents in metastatic non-small cell lung cancer (NSCLC) can result in improved quality of life and survival when compared with platinum-based chemotherapy. Novel response patterns such as pseudoprogression and hyperprogression, however, have been described and pose a challenge to treating physicians. Predictors of hyperprogressive disease (HPD) have not yet been identified. Evaluation and management by a multidisciplinary team involving medical and radiation oncologists, thoracic radiologists, and proceduralists is necessary to identify this subset of patients in a timely manner. Repeat biopsy distinguishes HPD from pseudoprogression and may eventually elucidate predictive biomarkers. We describe the epidemiology of these two phenomena, their diagnostic criteria, and their relevance for interventional pulmonologists. PMID:29607190

Internet-Based Survey Evaluating Use of Pain Medications and Attitudes of Radiation Oncology Patients Toward Pain Intervention

DOE Office of Scientific and Technical Information (OSTI.GOV)

Simone, Charles B.; Radiation Oncology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD; Vapiwala, Neha

Purpose: Pain is a common symptom among cancer patients, yet many patients do not receive adequate pain management. Few data exist quantifying analgesic use by radiation oncology patients. This study evaluated the causes of pain in cancer patients and investigated the reasons patients fail to receive optimal analgesic therapy. Methods and Materials: An institutional review board-approved, Internet-based questionnaire assessing analgesic use and pain control was posted on the OncoLink (available at (www.oncolink.org)) Website. Between November 2005 and April 2006, 243 patients responded. They were predominantly women (73%), white (71%), and educated beyond high school (67%) and had breast (38%), lungmore » (6%), or ovarian (6%) cancer. This analysis evaluated the 106 patients (44%) who underwent radiotherapy. Results: Of the 106 patients, 58% reported pain from their cancer treatment, and 46% reported pain directly from their cancer. The pain was chronic in 51% and intermittent in 33%. Most (80%) did not use medication to manage their pain. Analgesic use was significantly less in patients with greater education levels (11% vs. 36%, p = 0.002), with a trend toward lower use by whites (16% vs. 32%, p 0.082) and women (17% vs. 29%, p = 0.178). The reasons for not taking analgesics included healthcare provider not recommending medication (87%), fear of addiction or dependence (79%), and inability to pay (79%). Participants experiencing pain, but not taking analgesics, pursued alternative therapies for relief. Conclusions: Many radiation oncology patients experience pain from their disease and cancer treatment. Most study participants did not use analgesics because of concerns of addiction, cost, or failure of the radiation oncologist to recommend medication. Healthcare providers should have open discussions with their patients regarding pain symptoms and treatment.« less

2014-01-01

In a 2-part study, we first examined the results of 71 surveyed physicians who provided responses on how they address the management of patients who maintained either a pacemaker or a defibrillator during radiation treatment. Second, a case review study is presented involving 112 medical records reviewed at 18 institutions to determine whether there was a change in the radiation prescription for the treatment of the target cancer, the method of radiation delivery, or the method of radiation image acquisition. Statistics are provided to illustrate the level of administrative policy; the level of communication between radiation oncologists and heart specialists; American Joint Committee on Cancer (AJCC) staging and classification; National Comprehensive Cancer Network (NCCN) guidelines; tumor site; patient׳s sex; patient׳s age; device type; manufacturer; live monitoring; and the reported decisions for planning, delivery, and imaging. This survey revealed that 37% of patient treatments were considered for some sort of change in this regard, whereas 59% of patients were treated without regard to these alternatives when available. Only 3% of all patients were identified with an observable change in the functionality of the device or patient status in comparison with 96% of patients with normal behavior and operating devices. Documented changes in the patient׳s medical record included 1 device exhibiting failure at 0.3-Gy dose, 1 device exhibiting increased sensor rate during dose delivery, 1 patient having an irregular heartbeat leading to device reprogramming, and 1 patient complained of twinging in the chest wall that resulted in a respiratory arrest. Although policies and procedures should directly involve the qualified medical physicist for technical supervision, their sufficient involvement was typically not requested by most respondents. No treatment options were denied to any patient based on AJCC staging, classification, or NCCN practice standards. Copyright © 2014 American Association of Medical Dosimetrists.

Obtain baseline data of cell-phone usage in the medical (MO), surgical (SO) and radiation (RO) oncology community practicing in India. Indigenously prepared cell-phone usage related questionnaire was used in the present study after approval by the Institutional Ethics/Scientific Committees. The questionnaire had 41 items and was made to assess the cell-phone usage parameters, utility in clinical practice, awareness, and to compare parameters between oncology specialties. Between November 2009 and January 2010, the questionnaire was sent as an E-mail attachment to 200 oncologists in India. In all, 123 responses were received (61% responders); 84 (68.3%) were RO. The median age of responders was 35 years. Overall, 80% felt handicapped without cell-phone. The Mean cell-phone score, an index to assess overall usefulness over a score of 1-10, was 6.46 (median 7, standard deviation 1.709). There was no significant difference between RO, MO and SO in duration of usage (P = 0.235), number of cell-phones (P = 0.496), call duration per day (P = 0.490) and dependence on cell-phone (P = 0.574). Age of starting cell-phone usage was earlier in RO (P = 0.086). Professional usage was significantly more by MO and SO compared to RO (P < 0.001); however, the former were less aware of any potential cell-phone hazards compared to RO (P < 0.007). The results of the first such questionnaire based study have been presented. Most oncologists consider cell-phones a useful tool in patient care. More RO are aware of potential cell-phone hazards compared to non-RO's.

This study describes the supply of cancer care providers-physicians, nurse practitioners (NPs), and physician assistants (PAs)-in Nebraska and analyzes changes in the supply over a 5-year period. We used workforce survey data for the years 2008 to 2012 from the Health Professions Tracking Service to analyze the cancer care workforce supply in the state of Nebraska. The supply of cancer care providers was analyzed over the 5-year period on the basis of age, sex, specialty, and practice location; distribution of work hours for cancer care physicians was analyzed for 2012. From 2008 to 2012, there was a 3.3% increase in the number of cancer care physicians. Majority of the cancer care physicians (82.5%), NPs (81.1%), and PAs (80%) reported working in urban counties, whereas approximately half of the state's population resides in rural counties (47%). Compared with the national distribution, Nebraska has a lower proportion of medical oncologists, radiation oncologists, and pediatric hematologists/oncologists. The gap between the number of cancer care physicians age ≥ 64 years and the number younger than 40 years is slowly closing in Nebraska, with an increase in those age ≥ 64 years. Increasing cancer incidence and improved access to cancer care through the Affordable Care Act could increase demand for cancer care workers. Policymakers and legislators should consider a range of policies based on the best available data on the supply of cancer care providers and the demand for cancer care.

Phase I clinical trials are the gateway to effective new cancer treatments. Many physicians have difficulty when discussing Phase I clinical trials. Research demonstrates evidence of suboptimal communication. Little is known about communication strategies used by oncologists when recruiting patients for Phase I trials. We analyzed audio recorded Phase I consultations to identify oncologists' communication strategies. Subjects were consecutive cancer patients from six medical oncologists attending one of three outpatient clinics at a major Cancer Center in the United States. Sixteen patients signed informed consent for audio recording of their consultations in which a Phase I study was discussed. These were transcribed in full and analyzed to identify communication strategies. Six communication themes emerged from the analysis: (1) orienting, (2) educating patients, (3) describing uncertainty and prognosis, (4) persuading, (5) decision making, and (6) making a treatment recommendation. As expected, although there was some common ground between communication in Phase I and the Phase II and III settings, there were distinct differences. Oncologists used persuasive communication, made explicit recommendations, or implicitly expressed a treatment preference and were choice limiting. This highlights the complexity of discussing Phase I trials and the need to develop strategies to aid oncologists and patients in these difficult conversations. Patient centered communication that values patient preferences while preserving the oncologist's agenda can be a helpful approach to these discussions. Copyright © 2010 John Wiley & Sons, Ltd.

Oncology is a rapidly developing field with a growing number of publications every year. The main goal of this survey was to learn more about the information needs of oncologists and general practitioners. Data were collected using a standardised questionnaire developed in collaboration with the German Cancer Society (Deutsche Krebsgesellschaft) and the German Association of General Practitioners (Deutscher Hausärzteverband). A total of 495 questionnaires could be evaluated. Medical congresses were the preferred source of information for all participants. General practitioners preferred textbooks, while oncologists preferred journals and the Internet (all p < .001). Reasons for a lack of confidence during patient consultation were lack of time (60% of participants), lack of knowledge (61% of general practitioners and 26% of oncologists) and lack of data (>50%). Oncologists felt more confident in searching scientific databases than general practitioners did. Both groups required rapid access to transparent information. For general practitioners, reviews and comments by experts helped to put new information in the context of cancer treatment. Oncologists and general practitioners showed significantly different information needs and different ways to access specific information. In order to better integrate general practitioners while simultaneously serving the needs of oncologists, a database that is up to date, rapidly accessible and does not incur high costs would be helpful. © 2016 John Wiley & Sons Ltd.

Objective The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. Methods Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information on human resources, brachytherapy equipment, and suggestions for future directions of brachytherapy policy in Korea. Results The response rate of the survey was 88.3%. The average number of radiation oncologists per center was 2.3. At the time of survey, 28 centers (36.8%) provided brachytherapy to patients. Among the 28 brachytherapy centers, 15 (53.5%) were located in in the capital Seoul and its surrounding metropolitan areas. All brachytherapy centers had a high-dose rate system using 192Ir (26 centers) or 60Co (two centers). Among the 26 centers using 192Ir sources, 11 treated fewer than 40 patients per year. In the two centers using 60Co sources, the number of patients per year was 16 and 120, respectively. The most frequently cited difficulties in performing brachytherapy were cost related. A total of 21 centers had a plan to sustain the current brachytherapy system, and four centers noted plans to upgrade their brachytherapy system. Two centers stated that they were considering discontinuation of brachytherapy due to cost burdens of radioisotope source replacement. Conclusion The present study illustrated the current status of brachytherapy in Korea. Financial difficulties were the major barriers to the practice of brachytherapy. PMID:27102244

Purpose: A significant physician shortage has been projected to occur by 2025, and demand for oncologists is expected to outpace supply to an even greater degree. In response to this, many have called to increase the number of radiation oncology residency positions. The purpose of this study is to evaluate National Resident Matching Program (NRMP) data for the number of residency positions between 2004 and 2015 as well as the number and caliber of applicants for those positions and to compare radiation oncology to all residency specialties. Methods: NRMP data for all specialties participating in the match, including radiation oncology,more » were assessed over time examining the number of programs participating in the match, the number of positions offered, and the ratio of applicants to positions in the match from 2004 to 2015. Results: From 2004 to 2015, the number of total programs participating in the match has increased by 26.7%, compared to the increase of 28.6% in the number of radiation oncology programs from during the same time period. The total number of positions offered in the match increased by 53.4%, whereas radiation oncology positions increased by 56.3%, during the same time period. The ratio of applicants (defined as those selecting a specialty as their first or only choice) to positions for all specialties has fluctuated over this time period and has gone from 1.21 to 1.15, whereas radiation oncology experienced a decrease from 1.45 to 1.14. Conclusions: NRMP data suggest that senior medical student applications to radiation oncology are decreasing compared to those of other specialties. If we hope to continue to attract the best and brightest to enter our field, we must continue to support early exposure to radiation oncology, positive educational experiences, and dedicated mentorship to interested medical students.« less

From 2008-2013, the European indication for panitumumab required that patients' tumor KRAS exon 2 mutation status was known prior to starting treatment. To evaluate physician awareness of panitumumab prescribing information and how physicians prescribe panitumumab in patients with metastatic colorectal cancer (mCRC), two European multi-country, cross-sectional, observational studies were initiated in 2012: a physician survey and a medical records review. The first two out of three planned rounds for each study are reported. The primary objective in the physician survey was to estimate the prevalence of KRAS testing, and in the medical records review, it was to evaluate the effect of test results on patterns of panitumumab use. The medical records review study also included a pathologists' survey. In the physician survey, nearly all oncologists (299/301) were aware of the correct panitumumab indication and the need to test patients' tumor KRAS status before treatment with panitumumab. Nearly all oncologists (283/301) had in the past 6 months of clinical practice administered panitumumab correctly to mCRC patients with wild-type KRAS status. In the medical records review, 97.5% of participating oncologists (77/79) conducted a KRAS test for all of their patients prior to prescribing panitumumab. Four patients (1.3%) did not have tumor KRAS mutation status tested prior to starting panitumumab treatment. Approximately one-quarter of patients (85/306) were treated with panitumumab and concurrent oxaliplatin-containing chemotherapy; of these, 83/85 had confirmed wild-type KRAS status prior to starting panitumumab treatment. All 56 referred laboratories that participated used a Conformité Européenne-marked or otherwise validated KRAS detection method, and nearly all (55/56) participated in a quality assurance scheme. There was a high level of knowledge amongst oncologists around panitumumab prescribing information and the need to test and confirm patients' tumors as being wild-type KRAS prior to treatment with panitumumab, with or without concurrent oxaliplatin-containing therapy.

Current efforts to understand patient management in clinical practice are largely based on clinician surveys with uncertain reliability. The TRACC (Treatment of Recurrent and Advanced Colorectal Cancer) database is a multisite registry collecting comprehensive treatment and outcome data on consecutive metastatic colorectal cancer (mCRC) patients at multiple sites across Australia. This study aims to determine the accuracy of oncologists' impressions of real-word practice by comparing clinicians' estimates to data captured by TRACC. Nineteen medical oncologists from nine hospitals contributing data to TRACC completed a 34-question survey regarding their impression of the management and outcomes of mCRC at their own practice and other hospitals contributing to the database. Responses were then compared with TRACC data to determine how closely their impressions reflected actual practice. Data on 1300 patients with mCRC were available. Median clinician estimated frequency of KRAS testing within 6 months of diagnosis was 80% (range: 20-100%); the TRACC documented rate was 43%. Clinicians generally overestimated the rates of first-line treatment, particularly in patients over 75 years. Estimate for bevacizumab in first line was 60% (35-80%) versus 49% in TRACC. Estimated rate for liver resection varied substantially (5-35%), and the estimated median (27%) was inconsistent with the TRACC rate (12%). Oncologists generally felt their practice was similar to other hospitals. Oncologists' estimates of current clinical practice varied and were discordant with the TRACC database, often with a tendency to overestimate interventions. Clinician surveys alone do not reliably capture contemporary clinical practices in mCRC. © 2017 John Wiley & Sons Australia, Ltd.

Integrating palliative care into comprehensive cancer care.

PubMed

Abrahm, Janet L

2012-10-01

While there are operational, financial, and workforce barriers to integrating oncology with palliative care, part of the problem lies in ourselves, not in our systems. First, there is oncologists' "learned helplessness" from years of practice without effective medications to manage symptoms or training in how to handle the tough communication challenges every oncologist faces. Unless they and the fellows they train have had the opportunity to work with a palliative care team, they are unlikely to be fully aware of what palliative care has to offer to their patients at the time of diagnosis, during active therapy, or after developing advanced disease, or may believe that, "I already do that." The second barrier to better integration is the compassion fatigue many oncologists develop from caring for so many years for patients who, despite the oncologists' best efforts, suffer and die. The cumulative grief oncologists experience may go unnamed and unacknowledged, contributing to this compassion fatigue and burnout, both of which inhibit the integration of oncology and palliative care. Solutions include training fellows and practicing oncologists in palliative care skills (eg, in symptom management, psychological disorders, communication), preventing and treating compassion fatigue, and enhancing collaboration with palliative care specialists in caring for patients with refractory distress at any stage of disease. As more oncologists develop these skills, process their grief, and recognize the breadth of additional expertise offered by their palliative care colleagues, palliative care will become integrated into comprehensive cancer care.

Dental and maxillofacial abnormalities in long-term survivors of childhood cancer: effects of treatment with chemotherapy and radiation to the head and neck

Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and maxillofacial abnormalities were detected in 37 of the 45 (82%) radiated patients. Dental abnormalities comprised foreshortening and blunting of roots, incomplete calcification, premature closure of apices, delayed or arrested tooth development, and caries. Maxillofacial abnormalities comprised trismus, abnormal occlusal relationships, and facial deformities. The abnormalities were more severe in those patients who received radiationmore » at an earlier age and at higher dosages. Possible chemotherapeutic effects in five of 23 patients who received treatment for tumors located outside the head and neck region comprised acquired amelogenesis imperfecta, microdontia of bicuspid teeth, and a tendency toward thinning of roots with an enlarged pulp chamber. Dental and maxillofacial abnormalities should be recognized as a major consequence of maxillofacial radiation in long-term survivors of childhood cancer, and attempts to minimize or eliminate such sequelae should involve an effective interaction between radiation therapists, and medical and dental oncologists.« less

Peer review, especially prospective peer review, has been supported by professional organizations as an important element in optimal Radiation Oncology practice based on its demonstration of efficacy at detecting and preventing errors prior to patient treatment. Implementation of peer review is not without barriers, but solutions do exist to mitigate or eliminate some of those barriers. Peer review practice at our institution involves three key elements: new patient conference, treatment planning conference, and chart rounds. The treatment planning conference is an adaptation of the group consensus peer review model from radiology which utilizes a group of peers reviewing each treatment plan prior to implementation. The peer group in radiation oncology includes Radiation Oncologists, Physician Residents, Medical Physicists, Dosimetrists, and Therapists. Thus, technical and clinical aspects of each plan are evaluated simultaneously. Though peer review is held in high regard in Radiation Oncology, many barriers commonly exist preventing optimal implementation such as time intensiveness, repetition, and distraction from clinic time with patients. Through the use of automated review tools and commitment by individuals and administration in regards to staffing, scheduling, and responsibilities, these barriers have been mitigated to implement this Group Consensus Peer Review model into a Radiation Oncology Clinic. A Group Consensus Peer Review model has been implemented with strategies to address common barriers to effective and efficient peer review.

This research aimed to determine the levels of occupational stress, burnout and job satisfaction among radiation oncology workers across New Zealand. All oncology staff practising in all eight radiation oncology departments in New Zealand were invited to participate anonymously in a questionnaire, which consisted of the Maslach Burnout Inventory and measures of stress intensity associated with specific occupational stressors, stress reduction strategies and job satisfaction. A total of 171 (out of 349) complete responses were analysed using spss 19; there were 23 oncologists, 111 radiation therapists, 22 radiation nurses and 15 radiation physicists. All participants, regardless of profession, reported high stress levels associated with both patient-centred and organisational stressors. Participants scored high in all three domains of burnout: emotional exhaustion, depersonalisation and personal accomplishment. Interestingly, although organisational stressors predicted higher emotional exhaustion and emotional exhaustion predicted lower job satisfaction, patient stressors were associated with higher job satisfaction. Job satisfaction initiatives such as ongoing education, mentoring and role extension were supported by many participants as was addressing organisational stressors, such as lack of recognition and support from management and unrealistic expectations and demands. New Zealand staff exhibit higher levels of burnout than Maslach Burnout Inventory medical norms and oncology workers in previous international studies. © 2013 John Wiley & Sons Ltd.

[The enigma of the biological interpretation of the linear-quadratic model finally resolved? A summary for non-mathematicians].

The linear-quadratic (LQ) model is the only mathematical formula linking cellular survival and radiation dose that is sufficiently consensual to help radiation oncologists and radiobiologists in describing the radiation-induced events. However, this formula proposed in the 1970s and α and β parameters on which it is based remained without relevant biological meaning. From a collection of cutaneous fibroblasts with different radiosensitivity, built over 12 years by more than 50 French radiation oncologists, we recently pointed out that the ATM protein, major actor of the radiation response, diffuses from the cytoplasm to the nucleus after irradiation. The evidence of this nuclear shuttling of ATM allowed us to provide a biological interpretation of the LQ model in its mathematical features, validated by a hundred of radiosensitive cases. A mechanistic explanation of the radiosensitivity of syndromes caused by the mutation of cytoplasmic proteins and of the hypersensitivity to low-dose phenomenon has been proposed, as well. In this review, we present our resolution of the LQ model in the most didactic way. Copyright © 2016 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS.

The management of genitourinary malignancies requires a multidisciplinary care team composed of urologists, medical oncologists, and radiation oncologists. A genitourinary (GU) oncology clinical database is an invaluable resource for patient care and research. Although electronic medical records provide a single web-based record used for clinical care, billing, and scheduling, information is typically stored in a discipline-specific manner and data extraction is often not applicable to a research setting. A GU oncology database may be used for the development of multidisciplinary treatment plans, analysis of disease-specific practice patterns, and identification of patients for research studies. Despite the potential utility, there are many important considerations that must be addressed when developing and implementing a discipline-specific database. The creation of the GU oncology database including prostate, bladder, and kidney cancers with the identification of necessary variables was facilitated by meetings of stakeholders in medical oncology, urology, and radiation oncology at the University of North Carolina (UNC) at Chapel Hill with a template data dictionary provided by the Department of Urologic Surgery at Vanderbilt University Medical Center. Utilizing Research Electronic Data Capture (REDCap, version 4.14.5), the UNC Genitourinary OncoLogy Database (UNC GOLD) was designed and implemented. The process of designing and implementing a discipline-specific clinical database requires many important considerations. The primary consideration is determining the relationship between the database and the Institutional Review Board (IRB) given the potential applications for both clinical and research uses. Several other necessary steps include ensuring information technology security and federal regulation compliance; determination of a core complete dataset; creation of standard operating procedures; standardizing entry of free text fields; use of data exports, queries, and de-identification strategies; inclusion of individual investigators' data; and strategies for prioritizing specific projects and data entry. A discipline-specific database requires a buy-in from all stakeholders, meticulous development, and data entry resources to generate a unique platform for housing information that may be used for clinical care and research with IRB approval. The steps and issues identified in the development of UNC GOLD provide a process map for others interested in developing a GU oncology database. Copyright © 2014 Elsevier Inc. All rights reserved.

Few reports have thus far discussed the influence of economic factors on treatment decision-making by patients. The objective of the present study was to clarify the awareness among oncologists of health economics in cancer treatment. The present study was based on the questionnaire regarding health economics in cancer treatment carried out by the Japan Society of Clinical Oncology (JSCO) in July 2013. The subjects were trustees registered with JSCO. The survey investigated the influence of medical expenses on patient access to and selection of medical treatment in order to clarify the primary attributes of the respondents and their awareness of economics. The study also investigated the maximum allowable public medical expenses to prolong the life expectancy of a cancer patient by 1 year and the factors that can influence treatment selection. The 172 respondents had completed a mean of 30.3 ± 6.2 postgraduate years, and the mean number of patients they treated annually was 1323 ± 1963. The degree of treatment accessibility among patients was perceived positively by 112 (71.3 %) and negatively by 49 (28.7 %) of the respondents, irrespective of medical expenses. Of the 172 respondents, 66 (41.0 %) believed that the maximum allowable medical expenses for cancer treatment should be ≤4 million yen/LY, with 62 (39.8 %) reporting a value of 4.01-8 million yen/LY. The findings of this study suggest that a certain range of medical expenses has come to be regarded as the standard range of medical expenses for cancer treatment among oncologists, with answers based on the premise that patients should have access to effective medical treatment.

The attitude toward malnutrition varies considerably among oncologists and many malnourished cancer patients receive inadequate nutritional support. The aim of this brief report was to report the results of the exploratory national survey conducted by the Italian Society of Medical Oncology (AIOM) and the Italian Society of Artificial Nutrition and Metabolism (SINPE) before publication of a consensus document aimed at evaluating current attitudes toward malnutrition and management of nutrition, among Italian medical oncologists. Between January and July 2015, the AIOM and the SINPE conducted a national web-based exploratory survey to investigate the attitude of oncologists toward malnutrition, and the management of nutritional support, before publication of an intersociety consensus document. Of the 2375 AIOM members, 135 (5.7%) participated in the survey, with a satisfactory distribution across all Italian regions. Nutritional assessment and support were routinely integrated into patient care for 38 (28%) responders. According to 66 (49%) participants, nutritional assessment was carried out only at the patients' request (n = 62), or not at all (n = 4). Availability of clinical nutritionists was reported by 88 (65%) participants. For 131 responders (97%), nutritional status was decisive (n = 63) or often crucial (n = 68) in assessing whether anticancer treatment was practicable or would be tolerated. The low response rate may reflect the lack of awareness and consideration of nutritional issues among Italian oncologists. Although malnutrition and nutritional support seemed to be perceived by the responders as relevant factors for the efficacy of oncologic treatments, it seems that nutritional care practices may well be inappropriate. The lack of collaboration between oncologists and clinical nutritionists may be the first obstacle to overcome. Educational intersociety initiatives aimed at improving nutritional support management for cancer patients in Italy appear urgently needed. Copyright © 2016 Elsevier Inc. All rights reserved.

To develop an entry-to-practice quality and safety competency profile for radiation oncology residency. A comprehensive list of potential quality and safety competency items was generated from public and professional resources and interprofessional focus groups. Redundant or out-of-scope items were eliminated through investigator consensus. Remaining items were subjected to an international 2-round modified Delphi process involving experts in radiation oncology, radiation therapy, and medical physics. During Round 1, each item was scored independently on a 9-point Likert scale indicating appropriateness for inclusion in the competency profile. Items indistinctly ranked for inclusion or exclusion were re-evaluated through web conference discussion and reranked in Round 2. An initial 1211 items were compiled from 32 international sources and distilled to 105 unique potential quality and safety competency items. Fifteen of the 50 invited experts participated in round 1: 10 radiation oncologists, 4 radiation therapists, and 1 medical physicist from 13 centers in 5 countries. Round 1 rankings resulted in 80 items included, 1 item excluded, and 24 items indeterminate. Two areas emerged more prominently within the latter group: change management and human factors. Web conference with 5 participants resulted in 9 of these 24 items edited for content or clarity. In Round 2, 12 participants rescored all indeterminate items resulting in 10 items ranked for inclusion. The final 90 enabling competency items were organized into thematic groups consisting of 18 key competencies under headings adapted from Deming's System of Profound Knowledge.

Accurate delineation of the mediastinal and hilar lymph node regions is essential for a reproducible definition of target volumes used in conformal irradiation of non-small-cell lung cancer. The goal of this work was to generate a consensus to delineate these nodal regions based on definitions from the American Joint Committee on Cancer. A dedicated thoracic radiologist, thoracic surgeon, medical physicist, and three radiation oncologists were gathered to generate a three-dimensional radiologic description for the mediastinal and hilar nodal regions on axial CT scans. This paper proposes an atlas of most of the lymph node stations described by Mountain and Dresler. The CT boundaries of lymph node stations 1-2, 3, 4, 5, 6, 7, 8, 10-11 were defined on axial CT, along with image illustrations. These CT-based illustrative definitions will provide guidelines for clinical practice and studies evaluating incidental radiation in radiotherapy. Studies are ongoing at the University of Michigan to measure quantitatively the incidental nodal radiation received by patients with non-small-cell lung cancer.

The aim of this study was to develop an appropriate definition for vaginal cuff and paracolpium clinical target volume (CTV) for postoperative intensity modulated radiation therapy in patients with uterine cervical cancer. A working subgroup was organized within the Radiation Therapy Study Group of the Japan Clinical Oncology Group to develop a definition for the postoperative vaginal cuff and paracolpium CTV in December 2013. The group consisted of 5 radiation oncologists who specialized in gynecologic oncology and a gynecologic oncologist. A comprehensive literature review that included anatomy, surgery, and imaging fields was performed and was followed by multiple discreet face-to-face discussions and e-mail messages before a final consensus was reached. Definitions for the landmark structures in all directions that demarcate the vaginal cuff and paracolpium CTV were decided by consensus agreement of the working group. A table was created that showed boundary structures of the vaginal cuff and paracolpium CTV in each direction. A definition of the postoperative cervical cancer vaginal cuff and paracolpium CTV was developed. It is expected that this definition guideline will serve as a template for future radiation therapy clinical trial protocols, especially protocols involving intensity modulated radiation therapy.

Abstract Objective To explore health care provider (HCP) perspectives on the coordination of cancer care between FPs and cancer specialists. Design Qualitative study using semistructured telephone interviews. Setting Canada. Participants A total of 58 HCPs, comprising 21 FPs, 15 surgeons, 12 medical oncologists, 6 radiation oncologists, and 4 GPs in oncology. Methods This qualitative study is nested within a larger mixed-methods program of research, CanIMPACT (Canadian Team to Improve Community-Based Cancer Care along the Continuum), focused on improving the coordination of cancer care between FPs and cancer specialists. Using a constructivist grounded theory approach, telephone interviews were conducted with HCPs involved in cancer care. Invitations to participate were sent to a purposive sample of HCPs based on medical specialty, sex, province or territory, and geographic location (urban or rural). A coding schema was developed by 4 team members; subsequently, 1 team member coded the remaining transcripts. The resulting themes were reviewed by the entire team and a summary of results was mailed to participants for review. Main findings Communication challenges emerged as the most prominent theme. Five key related subthemes were identified around this core concept that occurred at both system and individual levels. System-level issues included delays in medical transcription, difficulties accessing patient information, and physicians not being copied on all reports. Individual-level issues included the lack of rapport between FPs and cancer specialists, and the lack of clearly defined and broadly communicated roles. Conclusion Effective and timely communication of medical information, as well as clearly defined roles for each provider, are essential to good coordination of care along the cancer care trajectory, particularly during transitions of care between cancer specialist and FP care. Despite advances in technology, substantial communication challenges still exist. This can lead to serious consequences that affect clinical decision making. PMID:27737996

To create a digital, online atlas for organs at risk (OAR) delineation in neuro-oncology based on high-quality computed tomography (CT) and magnetic resonance (MR) imaging. CT and 3 Tesla (3T) MR images (slice thickness 1 mm with intravenous contrast agent) were obtained from the same patient and subsequently fused. In addition, a 7T MR without intravenous contrast agent was obtained from a healthy volunteer. Based on discussion between experienced radiation oncologists, the clinically relevant organs at risk (OARs) to be included in the atlas for neuro-oncology were determined, excluding typical head and neck OARs previously published. The draft atlas was delineated by a senior radiation oncologist, 2 residents in radiation oncology, and a senior neuro-radiologist incorporating relevant available literature. The proposed atlas was then critically reviewed and discussed by European radiation oncologists until consensus was reached. The online atlas includes one CT-scan at two different window settings and one MR scan (3T) showing the OARs in axial, coronal and sagittal view. This manuscript presents the three-dimensional descriptions of the fifteen consensus OARs for neuro-oncology. Among these is a new OAR relevant for neuro-cognition, the posterior cerebellum (illustrated on 7T MR images). In order to decrease inter- and intra-observer variability in delineating OARs relevant for neuro-oncology and thus derive consistent dosimetric data, we propose this atlas to be used in photon and particle therapy. The atlas is available online at www.cancerdata.org and will be updated whenever required. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

Publication metrics are useful in evaluating academic faculty for awarding grants, recruitment, and promotion. A new metric, the relative citation ratio (RCR), was recently released by the National Institutes of Health (NIH); however, no benchmark data yet exist. We sought to create benchmark data for physician faculty in academic radiation oncology (RO) and analyze correlations associated with increased academic productivity. Citation database searches were performed for all US radiation oncologists affiliated with academic RO programs. Gender, NIH funding, career duration, academic rank, RCR, and weighted RCR were collected for each faculty. RCR and weighted RCR were calculated and compared between each subgroup of interest. RCR percentiles were also created for reference. A total of 1,299 RO physician faculty members from 75 institutions were included in the analysis. Overall, RO physician were very productive and influential with a mean RCR of 1.57 ± 1.53 SD and median RCR (interquartile range) of 1.32 (0.87-1.94). Academic rank, career duration, and NIH funding were associated with increased mean RCR and weighted RCR. Male gender and having a PhD were associated with an increased weighted RCR but not an increased mean RCR. Current academic radiation oncologists have a high mean RCR value relative to the benchmark NIH RCR value of 1. All subgroups analyzed had an RCR value above 1 with professor or chair and previous NIH funding having the highest RCR and weighted RCR values overall. These data may be useful for self-evaluation of ROs as well as evaluation of faculty by institutional and departmental leaders. Copyright © 2017 American College of Radiology.

World Health Organization classification has identified a dozen rare subtypes accounting for less than 10% of all breast cancers (BC), generally not taken into account in treatment guidelines. We evaluated professionals' attitudes toward decision-making regarding rare BC and consensus guidelines needs. In this international e-survey, 236 BC experts from all specialties were contacted through email to fill an online questionnaire about their practices. Eighty-six experts from 32 countries participated (36%); 50% medical oncologists, 21% surgeons, 17% pathologists, and 12% radiation oncologists. General BC care decisions were based on consensus guidelines in 77% of expert, whereas routine individual treatment decisions for BC were made by multi-disciplinary boards in 76%. Only 10% strongly considered rare BC should be treated following existing standard guidelines. Interestingly, 50-80% described individualizing treatment for rare BC according to pathologic subtype. More than 90% of experts would welcome international recommendations for rare BC. This large scale international multi-disciplinary survey revealed overarching concerns centered on several key themes: the lack of resources and data to address these less common BC; the heterogeneous management of rare BC depending on geographical location and specialist training; the demand for international consensus guidelines regarding their diagnosis and treatment. © 2015 Wiley Periodicals, Inc.

In the 2 and half decades reviewed (1970-1995), research established that chromosomal translocation, deletion, and DNA amplification are prerequisites to cancerogenesis and that oncogenes, tumor-suppressor genes, growth factors, and cytokines play crucial roles in the pathomechanism of cancer. Human papillomavirus, human immunodeficiency virus, herpes virus, and hepatitis B virus were identified as cancer-causing viruses. Several laboratory tests were developed for the detection of primary and recurrent cancers, and cancer prevention by screening methods was popularized. Sonography, computerized tomography, magnetic resonance imaging, positron emission tomography, excision of sentinel lymph nodes, and immunohistochemical techniques became routine procedures. Clinicopathologic staging and classification of tumors were standardized. Limited surgery, adjuvant and neoadjuvant chemoradiation, and the therapeutic use of monoclonal antibodies, tumor vaccines, and targeted chemotherapy became routine practice. The decline in cancer incidence and mortality demonstrated that cancer prevention and advancement in oncology are pivotal to success in the crusade against cancer. Above all, it was clearly established that the care of patients with cancer can be accomplished best in a multidisciplinary setting involving surgical oncologists, radiologists, radiation therapists, medical oncologists, surgical pathologists, and laboratory scientists. In conclusion, the 25 years from 1970 and 1995 are the high-water mark in clinical oncology, and this is the period when oncology turned from art to science. © 2015 American Cancer Society.

[Can medical oncologists talk about cure to their patient after localized breast cancer treatment?

Despite ongoing therapeutic advances in oncology, the use of the term cure in front of patients remains controversial. The word remission is often preferred in clinical practice. The purpose of this research is to explore how oncologists vary in their usage and definition of the word cure when talking to patients. Qualitative and exploratory pilot study conducted by semi structured interviews with a group of French oncologists about a clinical vignette of localized breast cancer treated by surgery and complete adjuvant treatment. Thirteen oncologists participated in this study between January and March 2016. They were divided into two groups according to whether or not they use the term cure in their clinical practice. A first group of five doctors define the word cure as the lasting absence of relapse of the disease. Because of their duty of transparency and the uncertainty of post-therapeutic relapse, these five doctors tend to never use the word cure. The analysis of the second group of eight doctors, who do use of the word cure in their practice, highlighted an absence of consensus on its definition. However, all of them justify their use of it with the importance of expressing positive emotions such as hope to patients. Our findings confirm that there are divergent understandings of the concept of cure between oncologists and how they manage prognosis uncertainty. Medical language is thus influenced by scientific knowledge, but also by doctors' personal values and ways of thinking, perhaps influencing the doctor-patient relationship in turn. This exploratory study will be extended on a wider scale to explore the coexistence of other elements of diversity. Copyright © 2018 Société Française du Cancer. Published by Elsevier Masson SAS.

In a 2-part study, we first examined the results of 71 surveyed physicians who provided responses on how they address the management of patients who maintained either a pacemaker or a defibrillator during radiation treatment. Second, a case review study is presented involving 112 medical records reviewed at 18 institutions to determine whether there was a change in the radiation prescription for the treatment of the target cancer, the method of radiation delivery, or the method of radiation image acquisition. Statistics are provided to illustrate the level of administrative policy; the level of communication between radiation oncologists and heart specialists;more » American Joint Committee on Cancer (AJCC) staging and classification; National Comprehensive Cancer Network (NCCN) guidelines; tumor site; patient's sex; patient's age; device type; manufacturer; live monitoring; and the reported decisions for planning, delivery, and imaging. This survey revealed that 37% of patient treatments were considered for some sort of change in this regard, whereas 59% of patients were treated without regard to these alternatives when available. Only 3% of all patients were identified with an observable change in the functionality of the device or patient status in comparison with 96% of patients with normal behavior and operating devices. Documented changes in the patient's medical record included 1 device exhibiting failure at 0.3-Gy dose, 1 device exhibiting increased sensor rate during dose delivery, 1 patient having an irregular heartbeat leading to device reprogramming, and 1 patient complained of twinging in the chest wall that resulted in a respiratory arrest. Although policies and procedures should directly involve the qualified medical physicist for technical supervision, their sufficient involvement was typically not requested by most respondents. No treatment options were denied to any patient based on AJCC staging, classification, or NCCN practice standards.« less

Clinical Practice Guidance for Radiotherapy Planning After Induction Chemotherapy in Locoregionally Advanced Head-and-Neck Cancer

Purpose: The use of induction chemotherapy (IC) for locoregionally advanced head-and-neck cancer is increasing. The response to IC often causes significant alterations in tumor volume and location and shifts in normal anatomy. Proper determination of the radiotherapy (RT) targets after IC becomes challenging, especially with the use of conformal and precision RT techniques. Therefore, a consensus conference was convened to discuss issues related to RT planning and coordination of care for patients receiving IC. Methods and Materials: Ten participants with special expertise in the various aspects of integration of IC and RT for the treatment of locoregionally advanced head-and-neck cancer,more » including radiation oncologists, medical oncologists, and a medical physicist, participated. The individual members were assigned topics for focused, didactic presentations. Discussion was encouraged after each presentation, and recommendations were formulated. Results: Recommendations and guidelines emerged that emphasize up-front evaluation by all members of the head-and-neck management team, high-quality baseline and postinduction planning scans with the patient in the treatment position, the use of preinduction target volumes, and the use of full-dose RT, even in the face of a complete response. Conclusion: A multidisciplinary approach is strongly encouraged. Although these recommendations were provided primarily for patients treated with IC, many of these same principles apply to concurrent chemoradiotherapy without IC. A rapid response during RT is quite common, requiring the development of two or more plans in a sizeable fraction of patients, and suggesting the need for similar guidance in the rapidly evolving area of adaptive RT.« less

Advance directives, acceleration of death, euthanasia and 'life-sustaining treatment' have sparked much heated debate among the media, the public, doctors and political leaders. We evaluate the personal opinions of Italian Association of Medical Oncology (AIOM) members. A 30-item questionnaire was developed and delivered to all 1,832 AIOM members. Six-hundred and eighty-five (37%) oncologists completed and returned the questionnaires. Sixty-three per cent felt culturally and psychologically prepared to face these issues. Fifty-four per cent believed that what had been decided while the patient enjoyed good health is no longer applicable in an advanced state of terminal illness. Thirty-nine per cent believed that doctors should abide by these directives, while 49% believed that this should be discussed on a case-by-case basis. Fourteen per cent of oncologists were favourable towards euthanasia and 42% only in particular circumstances. Fifty-six per cent had received at least one request for accelerating death: 15% consented, 50% discussed it with the patient and 31% refused. Advance directives, euthanasia, accelerated death and life-sustaining treatment represent considerable challenges for Italian oncologists. Although prepared to face these issues, AIOM members ask for a debate within the medical world and for a shared judicial regulation.

In October 2003, the Italian Association of Medical Oncology (AIOM) published its own guidelines on the use of granulocyte colony-stimulating factor (G-CSF). The present survey was conducted during the same period with the aim of collecting data on the current use of G-CSF to provide a starting point for future evaluations of the implementation of AIOM guidelines. From October 2003 to January 2004, 1591 AIOM members were asked to complete a questionnaire based on specific clinical scenarios, regarding the use of G-CSF for primary and secondary prophylaxis and treatment of neutropenia. The rate of response was 22%. For primary prophylaxis, the majority of physicians avoid using G-CSF, with no difference in cases of adjuvant, curative or palliative chemotherapy (CT). In fact, 67.2% to 74.9% would 'rarely or never' use G-CSF in the proposed clinical scenarios. In chemosensitive tumors, rather than reducing CT doses, 55.7% would use G-CSF as a secondary prophylaxis after afebrile neutropenia (AN), and 68.8% after febrile neutropenia (FN). In elderly patients experiencing FN, 35.7% would reduce the adjuvant CT doses and 23.1% would change the regimen. Most oncologists would use G-CSF to treat neutropenia, and the median duration of G-CSF treatment is less than 1 week and would depend on neutrophil count. Our survey shows that Italian oncologists are particularly oriented towards the use of G-CSF in clinical practice to maintain the CT dose intensity, and are sensitive to the prevention and treatment of not only FN, but also AN. Finally, Italian medical oncologists appear to be very cautious in introducing G-CSF when treating elderly patients.

Despite, vaccination is a highly effective and widely recommended for prevention of certain infections, vaccination coverage is very low. The purposes of this study were to evaluate the attitudes of medical oncologists towards vaccination and to identify predictors of intention to recommend vaccination in patients with cancer. A structured questionnaire is formed to evaluate the daily practice of vaccination. Turkish medical oncologists were invited to this study via email, SMS, or phone call. Questionnaire was filled out and the data were stored in an online survey platform. Two hundred seventy-three medical oncologists participated in the survey. Influenza, Pneumococcus, and hepatitis B were the most commonly recommended vaccines (87.1, 72.8, 67.0%, respectively). Patients with lung cancer, lymphoma and breast cancer were the main malignancies that medical oncologists suggest vaccination (68.1, 68.1, 24.6%, respectively). The most common times for vaccination were during remission/follow-up period (68.4%) or before beginning chemotherapy (64.1%). Only 23.4% of the physicians thought that their recommendation for vaccination was efficient and adequate. Lack of time and lack of knowledge or experience about vaccination are the most common limitations. There is a positive correlation between experience in the field and evaluating patients for vaccination (r = 0.390, p < 0.001); on the other hand, there is negative correlation between number of patients seen per day and evaluating patients for vaccination (r = -0.080, p = 0.18). Experience with autologous or allogeneic bone marrow transplant patients is related with more tendency to evaluate patients for vaccination (p < 0.001). Degree of experience in oncology especially in bone marrow transplant units and total number of patients seen per day are important predictors of vaccination practice in oncology. The frequency of recommendation increases with degree of experience, knowledge, and visit time per patient.

The Radiation Planning Assistant (RPA) is a system developed for the fully automated creation of radiotherapy treatment plans, including volume-modulated arc therapy (VMAT) plans for patients with head/neck cancer and 4-field box plans for patients with cervical cancer. It is a combination of specially developed in-house software that uses an application programming interface to communicate with a commercial radiotherapy treatment planning system. It also interfaces with a commercial secondary dose verification software. The necessary inputs to the system are a Treatment Plan Order, approved by the radiation oncologist, and a simulation computed tomography (CT) image, approved by the radiographer. The RPA then generates a complete radiotherapy treatment plan. For the cervical cancer treatment plans, no additional user intervention is necessary until the plan is complete. For head/neck treatment plans, after the normal tissue and some of the target structures are automatically delineated on the CT image, the radiation oncologist must review the contours, making edits if necessary. They also delineate the gross tumor volume. The RPA then completes the treatment planning process, creating a VMAT plan. Finally, the completed plan must be reviewed by qualified clinical staff.

The medical community is advocating for progressive improvement in the design of implantable cardioverter-defibrillators and implantable pacemakers to accommodate elevations in dose limitation criteria. With advancement already made for magnetic resonance imaging compatibility in some, a greater need is present to inform the radiation oncologist and medical physicist regarding treatment planning beam profile changes when such devices are in the field of a therapeutic radiation beam. Treatment plan modeling was conducted to simulate effects induced by Medtronic, Inc.-manufactured devices on therapeutic radiation beams. As a continuation of grant-supported research, we show that radial and transverse open beam profiles of amore » medical accelerator were altered when compared with profiles resulting when implantable pacemakers and cardioverter-defibrillators are placed directly in the beam. Results are markedly different between the 2 devices in the axial plane and the sagittal planes. Vast differences are also presented for the therapeutic beams at 6-MV and 18-MV x-ray energies. Maximum changes in percentage depth dose are observed for the implantable cardioverter-defibrillator as 9.3% at 6 MV and 10.1% at 18 MV, with worst distance to agreement of isodose lines at 2.3 cm and 1.3 cm, respectively. For the implantable pacemaker, the maximum changes in percentage depth dose were observed as 10.7% at 6 MV and 6.9% at 18 MV, with worst distance to agreement of isodose lines at 2.5 cm and 1.9 cm, respectively. No differences were discernible for the defibrillation leads and the pacing lead.« less

Background From 2008–2013, the European indication for panitumumab required that patients’ tumor KRAS exon 2 mutation status was known prior to starting treatment. To evaluate physician awareness of panitumumab prescribing information and how physicians prescribe panitumumab in patients with metastatic colorectal cancer (mCRC), two European multi-country, cross-sectional, observational studies were initiated in 2012: a physician survey and a medical records review. The first two out of three planned rounds for each study are reported. Methods The primary objective in the physician survey was to estimate the prevalence of KRAS testing, and in the medical records review, it was to evaluate the effect of test results on patterns of panitumumab use. The medical records review study also included a pathologists’ survey. Results In the physician survey, nearly all oncologists (299/301) were aware of the correct panitumumab indication and the need to test patients’ tumor KRAS status before treatment with panitumumab. Nearly all oncologists (283/301) had in the past 6 months of clinical practice administered panitumumab correctly to mCRC patients with wild-type KRAS status. In the medical records review, 97.5% of participating oncologists (77/79) conducted a KRAS test for all of their patients prior to prescribing panitumumab. Four patients (1.3%) did not have tumor KRAS mutation status tested prior to starting panitumumab treatment. Approximately one-quarter of patients (85/306) were treated with panitumumab and concurrent oxaliplatin-containing chemotherapy; of these, 83/85 had confirmed wild-type KRAS status prior to starting panitumumab treatment. All 56 referred laboratories that participated used a Conformité Européenne-marked or otherwise validated KRAS detection method, and nearly all (55/56) participated in a quality assurance scheme. Conclusions There was a high level of knowledge amongst oncologists around panitumumab prescribing information and the need to test and confirm patients’ tumors as being wild-type KRAS prior to treatment with panitumumab, with or without concurrent oxaliplatin-containing therapy.

The need for radiation oncologists and other radiation oncology (RO) professionals to lead quality improvement activities and contribute to shaping the future of our specialty is self-evident. Leadership knowledge, skills and behaviours, like other competencies, can be learned (Blumenthal et al., 2012). The objective of this study was to define a globally applicable competency set specific to radiation oncology for the CanMEDS Leader Role (Frank et al., 2015). A modified Delphi consensus process delivering two rounds of on-line surveys was used. Participants included trainees, radiation/clinical oncologists and other RO team members (radiation therapists, physicists, and nurses), professional educators and patients. 72 of 95 (76%) invitees from nine countries completed the Round 1 (R1) survey. Of the 72 respondents to RI, 70 completed Round 2 (R2) (97%). In R1, 35 items were deemed for 'inclusion' and 21 for 'exclusion', leaving 41 'undetermined'. After review of items, informed by participant comments, 14 competencies from the 'inclusion' group went into the final curriculum; 12 from the 'undetermined' group went to R2. In R2, 6 items reached consensus for inclusion. This process resulted in 20 RO Leader Role competencies with apparent global applicability. This is the first step towards developing learning, teaching and assessment tools for this important area of training. Copyright © 2017 Elsevier B.V. All rights reserved.

The aims of this study were to explore how oncologists and resident physicians practice end-of-life (EOL) discussions and to solicit their opinions on EOL discussions as a means to improve the quality of EOL care. A survey questionnaire was developed to explore the experiences and opinions about EOL discussions among oncologists and residents. Descriptive statistics, the t test, and the chisquare test were performed for the analyses. A total of 147 oncologists and 229 residents participated in this study. The study respondents reported diverse definitions of "terminal state," and mostrespondents tried to disclose the patient's condition to the patient and/or family members. Both groups were involved in EOL care discussions, with a rather low satisfaction level (57.82/100). The best timing to initiate discussionwas consideredwhen metastasis or disease recurrence occurred orwhen withdrawal of chemotherapy was anticipated. Furthermore, the study respondents suggested that patients and their family members should be included in the EOL discussion. Medical, legal, and ethical knowledge and communication difficulties along with practical issues were revealed as barriers and facilitators for EOL discussion. This study explored various perspectives of oncologists and resident physicians for EOL discussion. Since the Life-Sustaining-Treatment Decision-Making Act will be implemented shortly in Korea, now is the time for oncologists and residents to prepare themselves by acquiring legal knowledge and communication skills. To achieve this, education, training, and clinical tools for healthcare professionals are required.

Current state of prostate cancer treatment in Jamaica.

PubMed

Morrison, Belinda F; Aiken, William D; Mayhew, Richard

2014-01-01

Prostate cancer is the commonest cancer in Jamaica as well as the leading cause of cancer-related deaths. One report suggested that Jamaica has the highest incidence rate of prostate cancer in the world, with an age-standardised rate of 304/100,000 per year. The Caribbean region is reported to have the highest mortality rate of prostate cancer worldwide. Prostate cancer accounts for a large portion of the clinical practice for health-care practitioners in Jamaica. The Jamaica Urological Society is a professional body comprising 19 urologists in Jamaica who provide most of the care for men with prostate cancer in collaboration with medical oncologists, radiation oncologists, and a palliative care physician. The health-care system is structured in two tiers in Jamaica: public and private. The urologist-to-patient ratio is high, and this limits adequate urological care. Screening for prostate cancer is not a national policy in Jamaica. However, the Jamaica Urological Society and the Jamaica Cancer Society work synergistically to promote screening as well as to provide patient education for prostate cancer. Adequate treatment for localised prostate cancer is available in Jamaica in the forms of active surveillance, nerve-sparing radical retropubic prostatectomy, external beam radiation, and brachytherapy. However, there is a geographic maldistribution of centres that provide prostate cancer treatment, which leads to treatment delays. Also, there is difficulty in affording some treatment options in the private health-care sectors. Androgen deprivation therapy is available for treatment of locally advanced and metastatic prostate cancer and is subsidised through a programme called the National Health Fund. Second-line hormonal agents and chemotherapeutic agents are available but are costly to most of the population. The infrastructure for treatment of prostate cancer in Jamaica is good, but it requires additional technological advances as well as additional specialist services.

To understand decision making concerning adoption and nonadoption of accelerated partial breast radiotherapy (RT) prior to long-term randomized trial evidence. A total of 36 radiation oncologists and surgeons were recruited through purposive and snowball sampling strategies from September 2010 through January 2013. Semistructured phone interviews were conducted and audio-recorded and lasted 20-45 minutes. Qualitative analysis was conducted using a framework approach, iteratively exploring key concepts and emerging issues raised by subjects. Interviews were transcribed and imported into Atlas.ti v6. Transcripts were independently coded by 3 researchers shortly after each interview, followed by consensus development on each coded transcript. Barriers and facilitators of adoption, practice patterns, and informational/educational sources concerning accelerated partial breast RT were all assessed to determine major themes. Nearly half of physicians were surgeons (47%), and half were radiation oncologists (53%), with 61% overall in urban settings. Twenty-nine of the 36 physicians interviewed used brachytherapy-based partial breast RT. Five major factors were involved in physicians' decisions to adopt accelerated partial breast RT: facilitators encouraging adoption (e.g., enthusiastic colleagues and patient convenience), financial and prestige incentives, pressures to adopt (e.g., potential declines in referrals), judgment concerning acceptable level of scientific evidence, and barriers (e.g., not having appropriate machinery or referral mechanism in place). If technology was adopted, clinical guideline adherence varied. Technology adoption is based on financial and social pressures, along with often-limited scientific evidence and what seems "best" for patients. For technology adoption and diffusion to be rational and evidence-based, we must encourage appropriate financial payment models to curb use outside of research studies and promote development of additional treatment registries until sufficient evidence is gathered. © The Author(s) 2014.

This study investigated the impact of hospice care on end-of-life elderly patients with lung cancer in Taiwan. Data were collected from deceased inpatients with lung cancer who were at least 65 years old, using the National Health Insurance Research Database of 2004. A total of 1282 patients were enrolled, of whom 277 (21.6%) received hospice care (hospice-care group) and the other 1005 (78.4%) received general acute ward care (control group). The patients' age, gender, and institution of hospitalization did not differ significantly between the two groups, and most of the patients had chosen medical centers and their affiliated hospices for terminal care. The hospice-care group had a significantly shorter hospital stay and lower costs of hospitalization than the control group, with patients cared for primarily by family physicians and radiation oncologists (all p<0.05). The hospice-care group had an elevated incidence of co-morbid diabetes mellitus, higher scores on the Charlson Comorbidity Index, fewer acute lower respiratory conditions, and fewer invasive procedures than the control group (all p<0.05). Natural opium alkaloids were the most commonly prescribed drugs in the hospice-care group, whereas parenteral solutions were most frequently requested in the control group. Hospice care has provided a humane and cost-efficient pathway for end-of-life elderly patients with lung cancer. Parenteral nutrition/hydration should be limited for terminal care patients. Opioids should be promoted for the relief of pain and dyspnea in acute ward care. Family physicians and radiation oncologists play important roles in hospice care. Compared with the prevalence of hospice care in the United Kingdom and other developed countries, hospice care in Taiwan is in the position to be expanded. Copyright © 2012.

Despite approval by the Food and Drug Administration and consistent reports of the efficacy and safety of (90)Y-ibritumomab tiuxetan and (131)I-tositumomab, these therapies are infrequently used. This study investigates the opinions and patterns of the use of radioimmunotherapy by nuclear physicians, affiliated researchers, nuclear medicine technologists, and radiation oncologists and aims to identify possible barriers to the use of this promising therapy. An e-mail-based survey with 13 broad questions related to radioimmunotherapy was sent electronically to 13,221 Society of Nuclear Medicine members and radiation oncologists throughout the United States. Six hundred thirteen individuals (4.6%) responded to the electronic survey. Two hundred fifty-one responders (40.9%) had treated patients with non-Hodgkin lymphoma (NHL) with radioimmunotherapy in the last 24 mo. Of the responders, 29.5% used only (90)Y-ibritumomab tiuxetan, 7.6% used only (131)I-tositumomab, and 24.9% used both radiopharmaceuticals; 37.9% did not treat NHL with radioimmunotherapy. Most responders said their patients came from university hospitals (33.9%) or private offices (25.6%), and they mainly treated in a second-line (42.9%), third-line (35.6%), or consolidation (23.5%) setting. Major concerns were that referring oncologists and hematologists wanted to treat by themselves with nonradioactive compounds (mean ± SD, 3.418 ± 1.49) and that (90)Y-ibritumomab tiuxetan and (131)I-tositumomab were expensive (mean ± SD, 3.413 ± 1.35). Of the responders and involved physicians, 40.4% and 35.2%, respectively, did not know if their institution accepted Medicare patients for radioimmunotherapy. Almost 30% (29.6%) of the responders thought radioimmunotherapy would probably grow and 38.0% thought it would grow in importance in the future. Responders who did not administer radioimmunotherapy for NHL thought it took too much time to administer radioimmunotherapy (P < 0.01) and had concerns about the dosimetry procedure (P < 0.01) and radiation safety (P < 0.01). Individuals who perceived a negative future for radioimmunotherapy had significantly more concerns about the time-consuming administration process (P < 0.05) and the high cost of radioimmunotherapy (P < 0.05). Responders from academic centers had significantly fewer concerns about payment (P < 0.01), dosimetry (P < 0.01), and radiation safety (P < 0.01). Radioimmunotherapy was generally viewed positively by the surveyed population. However, limited referrals due to alternative nonradioactive therapies and logistic, educational, and economic concerns played an important role for subgroups in the perception of radioimmunotherapy for NHL.

Triphasic contrast enhanced CT simulation with bolus tracking for pancreas SBRT target delineation.

Godfrey, Devon J; Patel, Bhavik N; Adamson, Justus D; Subashi, Ergys; Salama, Joseph K; Palta, Manisha

Bolus-tracked multiphasic contrast computed tomography (CT) is often used in diagnostic radiology to enhance the visibility of pancreas tumors, but is uncommon in radiation therapy pancreas CT simulation, and its impact on gross tumor volume (GTV) delineation is unknown. This study evaluates the lesion conspicuity and consistency of pancreas stereotactic body radiation therapy (SBRT) GTVs contoured in the different contrast phases of triphasic CT simulation scans. Triphasic, bolus-tracked planning CT simulation scans of 10 consecutive pancreas SBRT patients were acquired, yielding images of the pancreas during the late arterial (LA), portal venous (PV), and either the early arterial or delayed phase. GTVs were contoured on each phase by a gastrointestinal-specialized radiation oncologist and reviewed by a fellowship-trained abdominal radiologist who specializes in pancreatic imaging. The volumes of the registered GTVs, their overlap ratio, and the 3-dimensional margin expansions necessary for each GTV to fully encompass GTVs from the other phases were calculated. The contrast difference between tumor and normal pancreas was measured, and 2 radiation oncologists rank-ordered the phases according to their value for the lesion-contouring task. Tumor-to-pancreas enhancement was on average much larger for the LA and PV than the delayed phase or early arterial phases; the LA and PV phases were also consistently preferred by the radiation oncologists. Enhancement differences among the phases resulted in highly variable GTV volumes with no observed trends. Overlap ratios ranged from 18% to 75% across all 3 phases, improving to 43% to 91% when considering only the preferred LA and PV phases. GTV expansions necessary to encompass all GTVs ranged from 0.3 to 1.8 cm for all 3 phases, improving slightly to 0.1 to 1.4 cm when considering just the LA and PV phases. For pancreas SBRT, we recommend combining the GTVs from a multiphasic CT simulation with bolus-tracking, including, at a minimum, a Boolean "OR" of the LA and PV phases.

Thiruthaneeswaran, N; Turner, S; Milross, C; Gogna, K

2014-03-01

Since 2005, radiation oncology trainees in Australia and New Zealand have had to undertake a piece of original research during training, and submit a manuscript, as first author, for senior peer-review. Satisfactory completion of this requirement is one component of eligibility to sit the Royal Australian and New Zealand College of Radiologists Fellowship examinations. The purpose of this study was to examine the value of this curriculum requirement, including the publication rates and potential barriers to trainee research. An online survey was sent to 116 radiation oncologists/trainees who trained since the mandatory research requirement was introduced (2005-2011). Questions concerned research topics, publications, subsequent research activity, perceptions on barriers to research and aids to conducting research during training. A web-based search of PubMed by author name was carried out to complete and verify publication statistics. In total, 108 (93.1%) of the 116 trainees across 20 centres who submitted their research papers to the Radiation Oncology Faculty Research Committee were successful in meeting the required standard first time. Half of these trainees ultimately published their paper in a peer-reviewed journal. Of trainees responding to the survey, 62% presented their research at a scientific meeting. Most of the studies were either retrospective (62.3%) or dosimetry/physics projects (10.1%). The main problems encountered in conducting projects were competing clinical commitments and lack of dedicated research time. Notably, long ethics approval processes, lack of supervision and statistical support for projects were not considered barriers. This mandatory research requirement ensures trainees initiate and complete at least one project during their training. Since the introduction of this curriculum component, half of the research projects have resulted in publication in a peer-reviewed journal. Increased 'protected time' and training in scientific writing and methods may improve publication rates and quality. This first review of the Australian and New Zealand radiation oncology trainee research requirement highlights areas that need to be addressed to further support and foster a research culture among junior radiation oncologists.

2009-07-15

Although a 12-month clinical internship is the traditional precursor to a radiation oncology residency, the continuance of this mandated training sequence has been questioned. This study was performed to evaluate the perceptions of current radiation oncology residents with respect to the value of their internship experience. A survey was sent to all US radiation oncology residents. Each was queried about whether they considered the internship to be a necessary prerequisite for a career as a radiation oncologist and as a physician. Preferences were listed on a Likert scale (1 = not at all necessary to 5 = absolutely necessary). Seventy-one percent considered the internship year mostly (Likert Scale 4) or absolutely necessary (Likert Scale 5) for their development as a radiation oncologist, whereas 19.1% answered hardly or not at all (Likert Scale 2 and 1, respectively). With respect to their collective considerations about the impact of the internship year on their development as a physician, 89% had a positive response, 5.8% had a negative response, and 4.7% had no opinion. Although both deemed the preliminary year favorably, affirmative answers were more frequent among erstwhile internal medicine interns than former transitional program interns. A majority of radiation oncology residents positively acknowledged their internship for their development as a specialist and an even greater majority valued it for their development as a physician. This affirmative opinion was registered more frequently by those completing an internal medicine internship compared with a transitional internship.

Leaflet manual of external beam radiation therapy for hepatocellular carcinoma: a review of the indications, evidences, and clinical trials.

PubMed

Rim, Chai Hong; Yoon, Won Sup

2018-01-01

The use of external beam radiation therapy (EBRT) in the treatment of hepatocellular carcinoma (HCC), which was rarely performed due to liver toxicity with a previous technique, has increased. Palliation of portal vein thrombosis, supplementation for insufficient transarterial chemoembolization, and provision of new curative opportunities using stereotactic body radiotherapy are the potential indications for use of EBRT. The mechanism of EBRT treatment, with its radiobiological and physical perspectives, differs from those of conventional medical treatment or surgery. Therefore, understanding the effects of EBRT may be unfamiliar to physicians other than radiation oncologists, especially in the field of HCC, where EBRT has recently begun to be applied. The first objective of this review was to concisely explain the indications for use of EBRT for HCC for all physicians treating HCC. Therefore, this review focuses on the therapeutic outcomes rather than the detailed biological and physical background. We also reviewed recent clinical trials that may extend the indications for use of EBRT. Finally, we reviewed the current clinical practice guidelines for the treatment of HCC and discuss the current recommendations and future perspectives.

Medical Student–Reported Outcomes of a Radiation Oncologist–Led Preclinical Course in Oncology: A Five-Year Analysis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Agarwal, Ankit; Koottappillil, Brian; Shah, Bhartesh

Purpose: There is a recognized need for more robust training in oncology for medical students. At our institution, we have offered a core dedicated oncology block, led by a radiation oncologist course director, during the second year of the medical school curriculum since the 2008-2009 academic year. Herein, we report the outcomes of the oncology block over the past 5 years through an analysis of student perceptions of the course, both immediately after completion of the block and in the third year. Methods and Materials: We analyzed 2 separate surveys. The first assessed student impressions of how well the course metmore » each of the course's learning objectives through a survey that was administered to students immediately after the oncology block in 2012. The second was administered after students completed the oncology block during the required radiology clerkship in the third year. All questions used a 5-level Likert scale and were analyzed by use of a Wilcoxon signed-rank test. Results: Of the 169 students who took the oncology course in 2012, 127 (75.1%) completed the course feedback survey. Over 73% of students agreed or strongly agreed that the course met its 3 learning objectives. Of the 699 medical students who took the required radiology clerkship between 2010 and 2013, 538 participated in the second survey, for a total response rate of 77%. Of these students, 368 (68.4%) agreed or strongly agreed that the course was effective in contributing to their overall medical education. Conclusion: Student perceptions of the oncology block are favorable and have improved across multiple categories since the inception of the course. Students self-reported that a dedicated preclinical oncology block was effective in helping identify the basics of cancer therapy and laying the foundation for clinical electives in oncology, including radiation oncology.« less

SU-F-E-12: Elective International Rotations in Medical Physics Residency Programs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Brown, D; Mundt, A; Einck, J

Purpose: The purpose of this educational program is to motivate talented, intelligent individuals to become stakeholders in the global effort to improve access to radiotherapy. Methods: The need to improve global access to radiotherapy has been clearly established and several organizations are making substantial progress in securing funding and developing plans to achieve this worthwhile goal. The incorporation of elective international rotations in residency programs may provide one possible mechanism to promote and support this future investment. We recently incorporated an elective 1-month international rotation into our CAMPEP accredited Medical Physics residency program, with our first rotation taking place inmore » Vietnam. A unique aspect of this rotation was that it was scheduled collaboratively with our Radiation Oncology residency program such that Radiation Oncology and Medical Physics residents traveled to the same clinic at the same time. Results: We believe the international rotation substantially enhances the educational experience, providing additional benefits to residents by increasing cross-disciplinary learning and offering a shared learning experience. The combined international rotation may also increase benefit to the host institution by modeling positive multidisciplinary working relationships between Radiation Oncologists and Medical Physicists. Our first resident returned with several ideas designed to improve radiotherapy in resource-limited settings – one of which is currently being pursued in collaboration with a vendor. Conclusion: The elective international rotation provides a unique learning experience that has the potential to motivate residents to become stakeholders in the global effort to improve access to radiotherapy. What better way to prepare the next generation of Medical Physicists to meet the challenges of improving global access to radiotherapy than to provide them with training experiences that motivate them to be socially conscious and equip them with the clinical and problem solving skills required to deliver effective treatments in resource limited settings?.« less

Traditional text-only versus multimedia-enhanced radiology reporting: referring physicians' perceptions of value.

PubMed

Sadigh, Gelareh; Hertweck, Timothy; Kao, Cristine; Wood, Paul; Hughes, Danny; Henry, Travis S; Duszak, Richard

2015-05-01

The aim of this study was to evaluate referring physicians' perceptions of multimedia-enhanced radiology reporting (MERR) as an alternative to traditional text-only radiology reporting. MERR supplements text-only reports by embedding user-friendly interactive hyperlinks to key images and graphically plotting target lesion size longitudinally over time. Of 402 physicians responding to a web-based survey, 200 (50 each medical oncologists, radiation oncologists, neurosurgeons, and pulmonologists) practicing in the United States fulfilled criteria to complete an online survey with questions focusing on satisfaction with current text-only reports and the perceived value of image- and data-enriched reporting. The mean respondent age was 46 years, with a mean of 15 years in posttraining clinical practice (85% men; 47% from academic medical centers). Although 80% were satisfied with the format of their current text-only radiology reports, 80% believed that MERR would represent an improvement. The most commonly reported advantages of MERR were "improved understanding of radiology findings by correlating images to text reports" (86%) and "easier access to images while monitoring progression of a disease/condition" (79%). Of the 28% of physicians with concerns about MERR implementation, the most common were that it was "too time intensive" (53%) and "the clinic workflow does not allow itself to view reports in such a fashion" (42%). Physicians indicated a strong increased likelihood of preferentially referring patients to (80%) and recommending peers to (79%) facilities that offer MERR. Most specialist referring physicians believe that interactive image- and data-embedded MERR represents an improvement over current text-only radiology reporting. Compared with current report formatting, most would preferentially refer patients and peers to facilities offering more meaningful image- and graphically enriched reporting platforms.

Purpose Pre-operative (pre-op) chemoradiation therapy (CRT) improves local control and reduces toxicity more than post-operative (post-op) CRT for the treatment of stages II/III rectal cancer, but studies suggest many patients still receive post-op CRT. We examined patient beliefs, and clinical and provider characteristics associated with receipt of recommended therapy. Methods We identified stage II/III rectal cancer patients who had primary site resection and CRT among subjects in the Cancer Care Outcomes Research and Surveillance Consortium, a population- and health system-based prospective cohort of newly diagnosed colorectal cancer patients from 2003 to 2005. Patient surveys and abstracted medical records were used to construct variables and determine sequence of CRT and surgery. Logistic regression was used to model the association between predictors and receipt of pre-op CRT. Results Of the 201 patients, 66% received pre-op and 34% received post-op CRT. Those visiting a medical oncologist and/or radiation oncologist prior to a surgeon had a 96% (95% CI, 92% to 100%) predicted probability of receiving pre-op CRT, compared to 48% (95% CI, 41% to 55%) for those visiting a surgeon first. Among those visiting a surgeon first, documentation of recommended staging procedures was associated with receiving pre-op CRT. Conclusion Sequence of provider visits and documentation of recommended staging procedures were important predictors of receiving pre-op CRT. Initial multidisciplinary evaluation led to better adherence to CRT guidelines. Further evaluation of provider characteristics, referral patterns and related health system processes should be undertaken to inform targeted interventions to reduce variation from recommended care.

Specialized palliative care (PC) services have emerged to address symptoms and provide end-of-life management for patients with brain tumors. The utilization patterns of PC in neuro-oncology are unknown. A 22-question survey was distributed to participants of the society for neuro-oncology annual meeting 2012 (n = 4487). Nonparametric methods including Wilcoxon two-sample and Kruskal-Wallis tests were used to assess differences in responses. 239 (5.3 %) evaluable responses were received; 79 % of respondents were physicians, and 17 % were nurses or midlevel providers. Forty-seven percent were medical or neuro-oncologists, 31 % neurosurgeons and 11 % radiation oncologists. Forty percent had no formal training in PC, 57 % had some formal training and 3 % completed a PC fellowship. Seventy-nine percent practiced in an academic setting. Of the respondents, 57 % referred patients to PC when symptoms required treatment and 18 % at end of life. Only 51 % of all providers felt comfortable dealing with end-of-life issues and symptoms, while 33 % did not. Fifty-one percent preferred a service named "Supportive Care" rather than "Palliative Care" (MDs > midlevel providers, p < 0.001), and 32 % felt that patient expectations for ongoing therapy hindered their ability to make PC referrals. Female gender, formal training in neuro-oncology and PC, and medical versus surgical neuro-oncology training were significantly associated with hospice referral, comfort in dealing with end-of-life issues, and ease of access to PC services. Provider level, specialty, gender, training in PC and neuro-oncology have significant impact on the utilization of PC and hospice in neuro-oncology.

NCCN Consensus Guidelines for the Diagnosis and Management of Breast Implant-Associated Anaplastic Large Cell Lymphoma.

2017-03-01

Published case series demonstrate a lack of treatment standardization for breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) with a wide variety of therapeutic strategies being employed at all stages of disease. The National Comprehensive Cancer Network (NCCN) annually publishes Clinical Practice Guidelines for Non-Hodgkin Lymphomas. For the first time, BIA-ALCL management will be included which signifies an important and needed guideline addition. The new BIA-ALCL guideline was achieved by a consensus of lymphoma oncologists, plastic surgeons, radiation oncologists, and surgical oncologists. NCCN guidelines focus on the diagnosis and management throughout the stages of many lymphoma subtypes based upon the most current data available. This article summarizes the essential recommendations and optimal therapeutic strategies of the NCCN guidelines critical to the plastic surgery community. We encourage international adoption of these BIA-ALCL treatment standards by our specialty societies across the oncology and surgery disciplines. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

2008-01-01

Patient participation in treatment decision-making is being increasingly advocated, although cancer treatments are often guideline-driven. Trade-offs between benefits and side effects underlying guidelines are made by clinicians. Evidence suggests that clinicians are inaccurate at predicting patient values. The aim was to assess what role oncologists and cancer patients prefer in deciding about treatment, and how they view patient participation in treatment decision-making. Seventy disease-free cancer patients and 60 oncologists (surgical, radiation, and medical) were interviewed about their role preferences using the Control Preferences Scale (CPS) and about their views on patient participation using closed- and open-ended questions. Almost all participants preferred treatment decisions to be the outcome of a shared process. Clinicians viewed participation more often as reaching an agreement, whereas 23% of patients defined participation exclusively as being informed. Of the participants, ⩾81% thought not all patients are able to participate and ⩾74% thought clinicians are not always able to weigh the pros and cons of treatment for patients, especially not quality as compared with length of life. Clinicians seemed reluctant to share probability information on the likely impact of adjuvant treatment. Clinicians should acknowledge the legitimacy of patients' values in treatment decisions. Guidelines should recommend elicitation of patient values at specific decision points. PMID:18781148

An exploration of the feasibility of radiation therapist participation in treatment reviews

DOE Office of Scientific and Technical Information (OSTI.GOV)

Monk, Clare Maree; Wrightson, Stephanie Jane; Smith, Tony Neil

2013-09-15

As radiation oncologists' (ROs') workload has increased over time, treatment review clinics have become recognized as an area of RO practice into which radiation therapist (RT) practice could extend. There has been limited utilization of RTs in this role in Australia and a paucity of data on the acceptability and opinions regarding RTs practising in this role in an Australian context. The purpose of this audit was to investigate the feasibility of RT participation in review clinics at Calvary Mater Newcastle. Feasibility was determined by two methods: an audit of 200 treatment reviews to determine medical intervention (MI) levels requiredmore » and a survey of 80 clinical staff to explore attitudes towards RT participation in clinics. Medical intervention was required in 59% (n = 118) of observed reviews, with the lowest being for breast (33%) and prostate (28%) cancers. MI peaked at 73% between fractions 16–20 and was lowest early and late in the treatment period at 48%. There were 60 responses to the staff survey. All but one respondent agreed that RTs would be willing to participate in treatment review clinics, but all five consultant ROs indicated they would not be willing to delegate reviews to RTs. Neither feasibility measure reached acceptable levels to recommend RT participation in treatment review clinics. Further investigation and RT education are required to help meet the future RO workforce shortfall. As MI rates are lowest for breast and prostate cancer RT participation could be targeted to these clinics.« less

To determine the employment status and location of recent Canadian radiation oncology (RO) graduates and to identify current workforce entry trends. A fill-in-the-blank spreadsheet was distributed to all RO program directors in December 2013 and June 2014, requesting the employment status and location of their graduates over the last 3 years. Visa trainee graduates were excluded. Response rate from program directors was 100% for both survey administrations. Of 101 graduates identified, 99 (98%) had known employment status and location. In the December survey, 5 2013 graduates (16%), 17 2012 graduates (59%), and 18 2011 graduates (75%) had permanent staff employment. Six months later, 5 2014 graduates (29%), 15 2013 graduates (48%), 24 2012 graduates (83%), and 21 2011 graduates (88%) had secured staff positions. Fellowships and temporary locums were common for those without staff employment. The proportion of graduates with staff positions abroad increased from 22% to 26% 6 months later. Workforce entry for most RO graduates was delayed but showed steady improvement with longer time after graduation. High emigration rates for jobs abroad signify domestic employment challenges for newly certified, Canadian-trained radiation oncologists. Coordination on a national level is required to address and regulate radiation oncologist supply and demand disequilibrium in Canada. Copyright © 2015 Elsevier Inc. All rights reserved.

Oncologist burnout and compassion fatigue: investigating time pressure at work as a predictor and the mediating role of work-family conflict.

PubMed

Kleiner, Sibyl; Wallace, Jean E

2017-09-11

Oncologists are at high risk of poor mental health. Prior research has focused on burnout, and has identified heavy workload as a key predictor. Compassion fatigue among physicians has generally received less attention, although medical specialties such as oncology may be especially at risk of compassion fatigue. We contribute to research by identifying predictors of both burnout and compassion fatigue among oncologists. In doing so, we distinguish between quantitative workload (e.g., work hours) and subjective work pressure, and test whether work-family conflict mediates the relationships between work pressure and burnout or compassion fatigue. In a cross-sectional study, oncologists from across Canada (n = 312) completed questionnaires assessing burnout, compassion fatigue, workload, time pressure at work, work-family conflict, and other personal, family, and occupational characteristics. Analyses use Ordinary Least Squares regression. Subjective time pressure at work is a key predictor of both burnout and compassion fatigue. Our results also show that work-family conflict fully mediates these relationships. Overall, the models explain more of the variation in burnout as compared to compassion fatigue. Our study highlights the need to consider oncologists' subjective time pressure, in addition to quantitative workload, in interventions to improve mental health. The findings also highlight a need to better understand additional predictors of compassion fatigue.

Objectives To describe current patterns of practice of radiation oncology peer review within a provincial cancer system, identifying barriers and facilitators to its use with the ultimate aim of process improvement. Design A survey of radiation oncology programmes at provincial cancer centres. Setting All cancer centres within the province of Ontario, Canada (n=14). These are community-based outpatient facilities overseen by Cancer Care Ontario, the provincial cancer agency. Participants A delegate from each radiation oncology programme filled out a single survey based on input from their multidisciplinary team. Outcome measures Rated importance of peer review; current utilisation; format of the peer-review process; organisation and timing; case attributes; outcomes of the peer-review process and perceived barriers and facilitators to expanding peer-review processes. Results 14 (100%) centres responded. All rated the importance of peer review as at least 8/10 (10=extremely important). Detection of medical error and improvement of planning processes were the highest rated perceived benefits of peer review (each median 9/10). Six centres (43%) reviewed at least 50% of curative cases; four of these centres (29%) conducted peer review in more than 80% of cases treated with curative intent. Fewer than 20% of cases treated with palliative intent were reviewed in most centres. Five centres (36%) reported usually conducting peer review prior to the initiation of treatment. Five centres (36%) recorded the outcomes of peer review on the medical record. Thirteen centres (93%) planned to expand peer-review activities; a critical mass of radiation oncologists was the most important limiting factor (median 6/10). Conclusions Radiation oncology peer-review practices can vary even within a cancer system with provincial oversight. The application of guidelines and standards for peer-review processes, and monitoring of implementation and outcomes, will require effective knowledge translation activities. PMID:23903814

Burnout in health care professionals could have serious negative consequences on quality of patient care, professional satisfaction and personal life. Our aim was to investigate the burnout prevalence, work and lifestyle factors potentially affecting burnout amongst European oncologists ≤40 (YOs). A survey was conducted using the validated Maslach Burnout Inventory (MBI) and additional questions exploring work/lifestyle factors. Statistical analyses were carried out to identify factors associated with burnout. Total of 737 surveys (all ages) were collected from 41 European countries. Countries were divided into six regions. Results from 595 (81%) YOs were included (81% medical oncologists; 52% trainees, 62% women). Seventy-one percent of YOs showed evidence of burnout (burnout subdomains: depersonalization 50%; emotional exhaustion 45; low accomplishment 35%). Twenty-two percent requested support for burnout during training and 74% reported no hospital access to support services. Burnout rates were significantly different across Europe (P < 0.0001). Burnout was highest in central European (84%) and lowest in Northern Europe (52%). Depersonalization scores were higher in men compared with women (60% versus 45% P = 0.0001) and low accomplishment was highest in the 26-30 age group (P < 0.01). In multivariable linear regression analyses, European region, work/life balance, access to support services, living alone and inadequate vacation time remained independent burnout factors (P < 0.05). This is the largest burnout survey in European Young Oncologists. Burnout is common amongst YOs and rates vary across Europe. Achieving a good work/life balance, access to support services and adequate vacation time may reduce burnout levels. Raising awareness, support and interventional research are needed. © The Author 2017. Published by Oxford University Press on behalf of the European Society for Medical Oncology. All rights reserved.

Purpose Oncologists in academic cancer centers usually generate professional fees that are insufficient to cover salaries and other expenses, despite significant clinical activity; therefore, supplemental funding is frequently required in order to support competitive levels of physician compensation. Relative value units (RVUs) allow comparisons of productivity across institutions and practice locations and provide a reasonable point of reference on which funding decisions can be based. Methods We reviewed the clinical productivity and other characteristics of oncology physicians practicing in 13 major academic cancer institutions with membership or shared membership in the National Comprehensive Cancer Network (NCCN). The objectives of this study were to develop tools that would lead to better-informed decision making regarding practice management and physician deployment in comprehensive cancer centers and to determine benchmarks of productivity using RVUs accrued by physicians at each institution. Three hundred fifty-three individual physician practices across the 13 NCCN institutions in the survey provided data describing adult hematology/medical oncology and bone marrow/stem-cell transplantation programs. Data from the member institutions participating in the survey included all American Medical Association Current Procedural Terminology (CPT®) codes generated (billed) by each physician during each organization's fiscal year 2003 as a measure of actual clinical productivity. Physician characteristic data included specialty, clinical full-time equivalent (CFTE) status, faculty rank, faculty track, number of years of experience, and total salary by funding source. The average adult hematologist/medical oncologist in our sample would produce 3,745 RVUs if he/she worked full-time as a clinician (100% CFTE), compared with 4,506 RVUs for a 100% CFTE transplant oncologist. Results and Conclusion Our results suggest specific clinical productivity targets for academic oncologists and provide a methodology for analyzing potential factors associated with clinical productivity and developing clinical productivity targets specific for physicians with a mix of research, administrative, teaching, and clinical salary support.

Oncologists in academic cancer centers usually generate professional fees that are insufficient to cover salaries and other expenses, despite significant clinical activity; therefore, supplemental funding is frequently required in order to support competitive levels of physician compensation. Relative value units (RVUs) allow comparisons of productivity across institutions and practice locations and provide a reasonable point of reference on which funding decisions can be based. We reviewed the clinical productivity and other characteristics of oncology physicians practicing in 13 major academic cancer institutions with membership or shared membership in the National Comprehensive Cancer Network (NCCN). The objectives of this study were to develop tools that would lead to better-informed decision making regarding practice management and physician deployment in comprehensive cancer centers and to determine benchmarks of productivity using RVUs accrued by physicians at each institution. Three hundred fifty-three individual physician practices across the 13 NCCN institutions in the survey provided data describing adult hematology/medical oncology and bone marrow/stem-cell transplantation programs. Data from the member institutions participating in the survey included all American Medical Association Current Procedural Terminology (CPT®) codes generated (billed) by each physician during each organization's fiscal year 2003 as a measure of actual clinical productivity. Physician characteristic data included specialty, clinical full-time equivalent (CFTE) status, faculty rank, faculty track, number of years of experience, and total salary by funding source. The average adult hematologist/medical oncologist in our sample would produce 3,745 RVUs if he/she worked full-time as a clinician (100% CFTE), compared with 4,506 RVUs for a 100% CFTE transplant oncologist. Our results suggest specific clinical productivity targets for academic oncologists and provide a methodology for analyzing potential factors associated with clinical productivity and developing clinical productivity targets specific for physicians with a mix of research, administrative, teaching, and clinical salary support.

Oncologists perform a range of pharmacological and nonpharmacological interventions to manage the symptoms of outpatients with advanced cancer. The aim of this study was to develop and test a symptom management performance checklist (SyMPeC) to review medical charts. First, the content of the checklist was determined by consensus of an interprofessional team. The SyMPeC was tested using the data set of the SAKK 96/06 E-MOSAIC (Electronical Monitoring of Symptoms and Syndromes Associated with Cancer) trial, which included six consecutive visits from 247 patients. In a test data set (half of the data) of medical charts, two people extracted and quantified the definitions of the parameters (content validity). To assess the inter-rater reliability, three independent researchers used the SyMPeC on a random sample (10% of the test data set), and Fleiss's kappa was calculated. To test external validity, the interventions retrieved by the SyMPeC chart review were compared with nurse-led assessment of patient-perceived oncologists' palliative interventions. Five categories of symptoms were included: pain, fatigue, anorexia/nausea, dyspnea, and depression/anxiety. Interventions were categorized as symptom specific or symptom unspecific. In the test data set of 123 patients, 402 unspecific and 299 symptom-specific pharmacological interventions were detected. Nonpharmacological interventions (n = 242) were mostly symptom unspecific. Fleiss's kappa for symptom and intervention detections was K = 0.7 and K = 0.86, respectively. In 1003 of 1167 visits (86%), there was a match between SyMPeC and nurse-led assessment. Seventy-nine percent (195 of 247) of patients had no or one mismatch. Chart review by SyMPeC seems reliable to detect symptom management interventions by oncologists in outpatient clinics. Nonpharmacological interventions were less symptom specific. A template for documentation is needed for standardization. Copyright © 2014 American Academy of Hospice and Palliative Medicine.

Miller-Clemente, R; Universidad de Oriente, Santiago De Cuba, Santiago de Cuba; Mendez-Perez, L

Purpose: To contribute to the professional profile of future medical physicists, technologists and physicians, and implement an adaptable educational strategy at both undergraduate and postgraduate levels. Methods: The Medical Physics Block of Electives (MPBE) designed was adapted to the Program of B.S. in Physics. The conferences and practical activities were developed with participatory methods, with interdisciplinary collaboration from research institutions and hospitals engaged on projects of Research, Development and Innovation (RDI). The scientific education was implemented by means of critical analysis of scientific papers and seminars where students debated on solutions for real research problems faced by medical physicists. Thismore » approach included courses for graduates not associated to educational programs of Medical Physics (MP). Results: The implementation of the MPBE began in September 2014, with the electives of Radiation MP and Introduction to Nuclear Magnetic Resonance. The students of second year received an Introduction to MP. This initiative was validated by the departmental Methodological Workshop, which promoted the full implementation of the MPBE. Both postgraduated and undergraduate trainees participated in practices with our DICOM viewer system, a local prototype for photoplethysmography and a home-made interface for ROC analysis, built with MATLAB. All these tools were designed and constructed in previous RDI projects. The collaborative supervision of University’s researchers with clinical medical physicists will allow to overcome the limitations of residency in hospitals, to reduce the workload for clinical supervisors and develop appropriate educational activities. Conclusion: We demonstrated the feasibility of adaptable educational strategies, considering available resources. This provides an innovative way for prospective medical physicists, technologists and radiation oncologists. This strategy can be implemented in several regions without formal programs of MP, like most of developing countries. Starting with undergraduate students would allow to reach appropriate certification faster than most of traditional or alternative approaches for education on MP.

The National Radiation Oncology Registry (NROR) is a collaborative initiative of the Radiation Oncology Institute and the American Society of Radiation Oncology, with input and guidance from other major stakeholders in oncology. The overarching mission of the NROR is to improve the care of cancer patients by capturing reliable information on treatment delivery and health outcomes. The NROR will collect patient-specific radiotherapy data electronically to allow for rapid comparison of the many competing treatment modalities and account for effectiveness, outcome, utilization, quality, safety, and cost. It will provide benchmark data and quality improvement tools for individual practitioners. The NROR steering committee has determined that prostate cancer provides an appropriate model to test the concept and the data capturing software in a limited number of sites. The NROR pilot project will begin with this disease-gathering treatment and outcomes data from a limited number of treatment sites across the range of practice; once feasibility is proven, it will scale up to more sites and diseases. When the NROR is fully implemented, all radiotherapy facilities, along with their radiation oncologists, will be solicited to participate in it. With the broader participation of the radiation oncology community, NROR has the potential to serve as a resource for determining national patterns of care, gaps in treatment quality, comparative effectiveness, and hypothesis generation to identify new linkages between therapeutic processes and outcomes. The NROR will benefit radiation oncologists and other care providers, payors, vendors, policy-makers, and, most importantly, cancer patients by capturing reliable information on population-based radiation treatment delivery.

The ecancer/SAC First International Prostate Cancer Symposium, held in Buenos Aires, included national, regional, and international experts in the field of prostate cancer. More than 200 professionals from a variety of areas (clinical urologists, pathologists, oncologists, biologists, imaging specialists, radiation therapists, and generalist doctors, among others) attended, and they proposed multidisciplinary management of prostate pathology from the start in concordance with the ideas set forth by the organising committee. A radiotherapy workshop was also held during the symposium, in which new techniques and their possible uses were specifically discussed. In addition to the local doctors, Dr Lilian Faroni (COI Group, Rio de Janeiro, Brazil), Dr Leonardo Carmona (Chilean Head and Neck Institute, Chile), and Dr Anthony Addesa (Jupiter Medical Centre, Florida, USA) also participated in this symposium.

Gliomas represent two thirds of all primary brain tumors. Their prognosis depends directly upon their level of differentiation. On MRI, tumoral aggressivity is highlighted by contrast uptake and the infiltrative nature of the lesion. Clinical suspicion must however be confirmed by histology and molecular markers become essential to refine the diagnosis and tailor the treatment. Isocytrate dehydrogenase (IDH) mutations, codeletion of 1p and 19q and the presence of methylation of the MGMT promoter identify a subgroup of gliomas with better prognosis and may help predict response to treatment. Management of patients with primary brain tumors should always be defined in multidisciplinar tumor boards involving neurosurgeons, oncologists, radiation oncologists, neuropathologists and neuroradiologists.

Purpose: Although a 12-month clinical internship is the traditional precursor to a radiation oncology residency, the continuance of this mandated training sequence has been questioned. This study was performed to evaluate the perceptions of current radiation oncology residents with respect to the value of their internship experience. Methods and Materials: A survey was sent to all US radiation oncology residents. Each was queried about whether they considered the internship to be a necessary prerequisite for a career as a radiation oncologist and as a physician. Preferences were listed on a Likert scale (1 = not at all necessary to 5more » = absolutely necessary). Results: Seventy-one percent considered the internship year mostly (Likert Scale 4) or absolutely necessary (Likert Scale 5) for their development as a radiation oncologist, whereas 19.1% answered hardly or not at all (Likert Scale 2 and 1, respectively). With respect to their collective considerations about the impact of the internship year on their development as a physician, 89% had a positive response, 5.8% had a negative response, and 4.7% had no opinion. Although both deemed the preliminary year favorably, affirmative answers were more frequent among erstwhile internal medicine interns than former transitional program interns. Conclusions: A majority of radiation oncology residents positively acknowledged their internship for their development as a specialist and an even greater majority valued it for their development as a physician. This affirmative opinion was registered more frequently by those completing an internal medicine internship compared with a transitional internship.« less

Lots of controversies were found about the treatment in relation to radiation therapy (RT) for esophageal squamous cell carcinoma (ESCC). We designed a questionnaire of these controversies to do a pan-Chinese survey of radiation oncologists (ROs). For operable ESCC, 53% ROs chose surgery plus postoperative chemoradiotherapy (CRT), while 40% chose preoperative CRT plus surgery. For target volume of postoperative RT, most ROs (92%) would delineate tumor bed plus involved lymph nodes region before surgery. For definitive RT, most ROs (81%) would give patients higher RT dose to 60-65Gy. For radiation target volume, most ROs would give patients prophylactic irradiation of the bilateral superclavicular-lymph nodes region for cervical ESCC (93%), and the left gastric lymph nodes region for lower thoracic ESCC (72%). For the treatment of mediastinal lymph nodes, 72% ROs preferred elective nodal irradiation, while 28% did the involved nodal irradiation. For concurrent chemotherapy regimen, PF (5-Fu + cisplatin) and TP (cisplatin + paclitaxel) were used widely (49% and 46%, respectively). During simulation, four-dimensional computer tomography (4D CT) was not widely used (48%), even for cervical or lower thoracic ESCC (52%). For daily RT delivery, only 66% ROs would perform imaging guidance RT daily. In summary, more controversies existed in the treatment of ESCC with RT in China, including treatment strategy, radiation dose and target contour. Future goals include standardization of treatment strategy, radiation dose, and target contour, and application of 4D CT and daily imaging guidance, and pursuit of randomized trials in Chinese population.

An ongoing PACS project at our facility has been expanded to include providing and managing images used for routine clinical operation of the department of radiation oncology. The intent of our investigation has been to enable out clinical radiotherapy service to enter the tele-medicine environment through the use of a PACS system initially implemented in the department of radiology. The backbone for the imaging network includes five CT and three MR scanners located across three imaging centers. A PC workstation in the department of radiation oncology was used to transmit CT imags to a satellite facility located approximately 60 miles from the primary center. Chest CT images were used to analyze network transmission performance. Connectivity established between the primary department and satellite has fulfilled all image criteria required by the oncologist. Establishing the link tot eh oncologist at the satellite diminished bottlenecking of imaging related tasks at the primary facility due to physician absence. A 30:1 compression ratio using a wavelet-based algorithm provided clinically acceptable images treatment planning. Clinical radiotherapy images can be effectively managed in a wide- area-network to link satellite facilities to larger clinical centers.

Observational studies demonstrate links between patient-centered communication, quality of life (QOL), and aggressive treatments in advanced cancer, yet few randomized clinical trials (RCTs) of communication interventions have been reported. To determine whether a combined intervention involving oncologists, patients with advanced cancer, and caregivers would promote patient-centered communication, and to estimate intervention effects on shared understanding, patient-physician relationships, QOL, and aggressive treatments in the last 30 days of life. Cluster RCT at community- and hospital-based cancer clinics in Western New York and Northern California; 38 medical oncologists (mean age 44.6 years; 11 (29%) female) and 265 community-dwelling adult patients with advanced nonhematologic cancer participated (mean age, 64.4 years, 146 [55.0%] female, 235 [89%] white; enrolled August 2012 to June 2014; followed for 3 years); 194 patients had participating caregivers. Oncologists received individualized communication training using standardized patient instructors while patients received question prompt lists and individualized communication coaching to identify issues to address during an upcoming oncologist visit. Both interventions focused on engaging patients in consultations, responding to emotions, informing patients about prognosis and treatment choices, and balanced framing of information. Control participants received no training. The prespecified primary outcome was a composite measure of patient-centered communication coded from audio recordings of the first oncologist visit following patient coaching (intervention group) or enrollment (control). Secondary outcomes included the patient-physician relationship, shared understanding of prognosis, QOL, and aggressive treatments and hospice use in the last 30 days of life. Data from 38 oncologists (19 randomized to intervention) and 265 patients (130 intervention) were analyzed. In fully adjusted models, the intervention resulted in clinically and statistically significant improvements in the primary physician-patient communication end point (adjusted intervention effect, 0.34; 95% CI, 0.06-0.62; P = .02). Differences in secondary outcomes were not statistically significant. A combined intervention that included oncologist communication training and coaching for patients with advanced cancer was effective in improving patient-centered communication but did not affect secondary outcomes. clinicaltrials.gov Identifier: NCT01485627.

Geriatric oncology (GO) is a discipline that focuses on the management of elderly patients with cancer. The Spanish Society of Medical Oncology (SEOM) created a Working group dedicated to geriatric oncology in February 2016. The main goal of this study was to describe the current situation in Spain regarding the management of elderly cancer patients through an online survey of medical oncologists. A descriptive survey was sent to several hospitals by means of the SEOM website. A personal e-mail was also sent to SEOM members. Between March 2016 and April 2017, 154 answers were collected. Only 74 centers (48%) had a geriatrics department and a mere 21 (14%) medical oncology departments had a person dedicated to GO. The vast majority (n = 135; 88%) had the perception that the number of elderly patients with cancer seen in clinical practice had increased. Eighteen (12%) oncologists had specific protocols and geriatric scales were used at 55 (31%) centers. Almost all (92%) claimed to apply special management practices using specific tools. There was agreement that GO afforded certain potential advantages. Finally, 99% of the oncologists surveyed believed it and that training in GO had to be improved. From the nationwide survey promoted by the Spanish Geriatric Oncology Working Group on behalf of SEOM, we conclude that there is currently no defined care structure for elderly cancer patients. There is an increasing perception of the need for training in GO. This survey reflects a reality in which specific needs are perceived.

Patient treatment preferences for the management of anxiety and depression influence adherence to treatment and treatment outcomes, yet the preferences of patients with breast cancer for provider-specific pharmacologic management of anxiety and depression is unknown. This study examined the antidepressant prescriber preferences of patients with breast cancer and their preferences for treatment by a mental health professional. Patients with breast cancer (stages 0 to IV) were asked two questions: “Would you be willing to have your oncologist treat your depression or anxiety with an antidepressant medication if you were to become depressed or anxious at any point during your treatment?” and “Would you prefer to be treated by a psychiatrist or mental health professional for problems with either anxiety or depression?” In addition, the Distress Thermometer and Problem List, Hospital Anxiety and Depression Scale, Risky Families Questionnaire, and demographic information were assessed. One hundred twenty-five participants completed the study. A total of 60.4% were willing to accept an antidepressant from an oncologist, and 26.3% preferred treatment by a mental health professional. The 77.3% who were willing to receive an antidepressant from their oncologist reported either no preference or that treatment by a mental health professional did not matter (P = .01). Participants taking antidepressants (P = .02) or reporting high chronic stress (P = .03) preferred a mental health professional. The majority of patients accepted antidepressant prescribing by their oncologist; only a minority preferred treatment by a mental health professional. These findings suggest that promoting education of oncologists to assess psychological symptoms and manage anxiety and depression as a routine part of an outpatient visit is beneficial Copyright © 2016 by American Society of Clinical Oncology.

Young adults with cancer are at an increased risk of suicidal ideation. To the authors' knowledge, the impact of the patient-oncologist alliance on suicidal ideation has not been examined to date. The current study examined the relationship between the patient-oncologist therapeutic alliance and suicidal ideation in young adults with advanced cancer. A total of 93 young adult patients (aged 20 years-40 years) with incurable, recurrent, or metastatic cancer were evaluated by trained interviewers. Suicidal ideation was assessed with the Yale Evaluation of Suicidality scale, dichotomized into a positive and negative score. Predictors included diagnoses of major depressive disorder and posttraumatic stress disorder, physical quality of life, social support, and use of mental health and supportive care services. The Human Connection Scale, dichotomized into a strong (upper third) and weak (lower two-thirds) therapeutic alliance, assessed the strength of the patients' perceived oncologist alliance. Approximately 22.6% of patients screened positive for suicidal ideation. Patients with a strong therapeutic alliance were found to be at reduced risk of suicidal ideation after controlling for confounding influences of cancer diagnosis, Karnofsky performance status, number of physical symptoms, physical quality of life, major depressive disorder, posttraumatic stress disorder, and social support. A strong therapeutic alliance was also associated with a reduced risk of suicidal ideation after controlling for mental health discussions with health care providers and use of mental health interventions. The patient-oncologist alliance was found to be a robust predictor of suicidal ideation and provided better protection against suicidal ideation than mental health interventions, including psychotropic medications. Oncologists may significantly influence patients' mental health and may benefit from training and guidance in building strong alliances with their young adult patients. © 2014 American Cancer Society.

Increasing faculty participation in resident education and providing cost-effective self-assessment module credit to faculty through resident-generated didactics.

Board certified radiation oncologists and medical physicists are required to earn self-assessment module (SAM) continuing medical education (CME) credit, which may require travel costs or usage fees. Data indicate that faculty participation in resident teaching activities is beneficial to resident education. Our hypothesis was that providing the opportunity to earn SAM credit in resident didactics would increase faculty participation in and improve resident education. SAM applications, comprising CME certified category 1 resident didactic lectures and faculty-generated questions with respective answers, rationales, and references, were submitted to the American Board of Radiology for formal review. Surveys were distributed to assess main academic campus physician, affiliate campus physician, physicist, and radiation oncology resident impressions regarding the quality of the lectures. Survey responses were designed in Likert-scale format. Sign-test was performed with P < .05 considered statistically different from neutral. First submission SAM approval was obtained for 9 of 9 lectures to date. A total of 52 SAM credits have been awarded to 4 physicists and 7 attending physicians. Main academic campus physician and affiliate campus physician attendance increased from 20% and 0%, respectively, over the 12 months preceding CME/SAM lectures, to 55.6% and 20%, respectively. Survey results indicated that the change to SAM lectures increased the quality of resident lectures (P = .001), attending physician participation in resident education (P < .0001), physicist involvement in medical resident education (P = .0006), and faculty motivation to attend resident didactics (P = .004). Residents reported an increased amount of time required to prepare lectures (P = .008). We are the first department, to our knowledge, to offer SAM credit to clinical faculty for participation in resident-generated didactics. Offering SAM credit at resident lectures is a cost-effective alternative to purchasing SAM resources, increases faculty attendance, and may improve the quality of radiation oncology resident education.

A DICOM-RT radiation oncology ePR with decision support utilizing a quantified knowledge base from historical data

Documet, Jorge R.; Liu, Brent; Le, Anh; Law, Maria

2008-03-01

During the last 2 years we have been working on developing a DICOM-RT (Radiation Therapy) ePR (Electronic Patient Record) with decision support that will allow physicists and radiation oncologists during their decision-making process. This ePR allows offline treatment dose calculations and plan evaluation, while at the same time it compares and quantifies treatment planning algorithms using DICOM-RT objects. The ePR framework permits the addition of visualization, processing, and analysis tools, which combined with the core functionality of reporting, importing and exporting of medical studies, creates a very powerful application that can improve the efficiency while planning cancer treatments. Usually a Radiation Oncology department will have disparate and complex data generated by the RT modalities as well as data scattered in RT Information/Management systems, Record & Verify systems, and Treatment Planning Systems (TPS) which can compromise the efficiency of the clinical workflow since the data crucial for a clinical decision may be time-consuming to retrieve, temporarily missing, or even lost. To address these shortcomings, the ACR-NEMA Standards Committee extended its DICOM (Digital Imaging & Communications in Medicine) standard from Radiology to RT by ratifying seven DICOM RT objects starting in 1997 [1,2]. However, they are not broadly used yet by the RT community in daily clinical operations. In the past, the research focus of an RT department has primarily been developing new protocols and devices to improve treatment process and outcomes of cancer patients with minimal effort dedicated to integration of imaging and information systems. Our attempt is to show a proof-of-concept that a DICOM-RT ePR system can be developed as a foundation to perform medical imaging informatics research in developing decision-support tools and knowledge base for future data mining applications.

Metronomic chemotherapy refers to the administration of low doses of cytotoxic agents over a prolonged period of time with no or only short drug-free intervals. It is designed to overcome acquired tumor resistance to chemotherapy and reduce neo-angiogenesis despite a lower toxicity than with standard chemotherapy. The role of metronomic chemotherapy remains controversial, and its optimal therapeutic use has not yet been defined. The present survey was designed as a short questionnaire and was sent to the medical oncologists registered with Medikey, a national database listing all the Italian oncology specialists linked with the Italian Council of Medical Oncology Hospital Consultants (Collegio Italiano Primari Oncologi Medici Ospedalieri, CIPOMO) and the Italian Association of Medical Oncology (Associazione Italiana di Oncologia Medica, AIOM). The questionnaire was completed on a voluntary basis and it was totally anonymous. The questionnaire was sent to 3,289 oncologists, and 191 (5.8%) actively participated in the survey. Seventy-two percent of responders declared that they had administered a regimen of metronomic chemotherapy at least once. Metronomic chemotherapy is commonly used in advanced breast cancer patients, and in most cases it was prescribed after failure of at least two lines of treatment. Oral agents such as cyclophosphamide, capecitabine, methotrexate and vinorelbine were the most commonly prescribed drugs. Nearly 60% of responders was believed to have significantly less toxicity with metronomic chemotherapy than with standard chemotherapy. The sample of oncologists who participated in the survey is small but it appears to be representative of the Italian medical oncology community. The answers to the questionnaire indicate a significant interest in metronomic chemotherapy, which is apparently widely prescribed. This is the first large national survey on the use of metronomic chemotherapy. Considering the results, larger research on metronomic chemotherapy is strongly warranted.

New radiation therapy modalities have broadened treatment options for older women with breast cancer, but it is unclear how clinical factors, geographic region, and physician preference affect the choice of radiation therapy modality. We used the Surveillance, Epidemiology, and End Results-Medicare database to identify women diagnosed with stage I-III breast cancer from 1998 to 2007 who underwent breast-conserving surgery. We assessed the temporal trends in, and costs of, the adoption of intensity modulated radiation therapy (IMRT) and brachytherapy. Using hierarchical logistic regression, we evaluated the relationship between the use of these new modalities and patient and regional characteristics. Of 35,060 patients, 69.9% received conventional external beam radiation therapy (EBRT). Although overall radiation therapy use remained constant, the use of IMRT increased from 0.0% to 12.6% from 1998 to 2007, and brachytherapy increased from 0.7% to 9.0%. The statistical variation in brachytherapy use attributable to the radiation oncologist and geographic region was 41.4% and 9.5%, respectively (for IMRT: 23.8% and 22.1%, respectively). Women undergoing treatment at a free-standing radiation facility were significantly more likely to receive IMRT than were women treated at a hospital-based facility (odds ratio for IMRT vs EBRT: 3.89 [95% confidence interval, 2.78-5.45]). No such association was seen for brachytherapy. The median radiation therapy cost per treated patient increased from $5389 in 2001 to $8539 in 2007. IMRT and brachytherapy use increased substantially from 1998 to 2007; overall, radiation therapy costs increased by more than 50%. Radiation oncologists played an important role in treatment choice for both types of radiation therapy, whereas geographic region played a bigger role in the use of IMRT than brachytherapy.

Women undergoing treatment at a free-standing radiation facility were significantly more likely to receive IMRT than were women treated at a hospital-based facility (odds ratio for IMRT vs EBRT: 3.89 [95% confidence interval, 2.78-5.45]). No such association was seen for brachytherapy. The median radiation therapy cost per treated patient increased from $5389 in 2001 to $8539 in 2007. Conclusions: IMRT and brachytherapy use increased substantially from 1998 to 2007; overall, radiation therapy costs increased by more than 50%. Radiation oncologists played an important role in treatment choice for both types of radiation therapy, whereas geographic region played a bigger role in the use of IMRT than brachytherapy.« less

The fast growing demand and the shortage of resources are pushing toward more efficient models of survivorship care delivery. The Associazione Italiana di Oncologia Medica (AIOM) established an interdisciplinary working group with the purpose of promoting organizational improvements at the national level. A survey aimed at assessing attitudes and feelings of oncologists was considered preliminary to further initiatives. A 25-item questionnaire, sent to the mailing list of the Society, explored the following issues on the practice of breast and colorectal cancer patients' follow up: 1) organization; 2) clinical features; 3) feelings about the different meanings of follow-up. Ninety-one oncologists of 160 institutions (57%) answered to the questionnaire. Although follow up is considered a distinct oncological activity in 68%, a fully shared organization between specialists is not common and communications with Primary Care Physicians are not structured in the majority of the cases. Fifty-five and 30% of the oncologists follow breast and colorectal cancer patients indefinitely. In case of discharge a survivorship care plan is delivered in only 9%. The majority of respondents do not hold a role of follow up in mortality reduction. Although survivorship care represents a significant part of the oncologists' workload, an "oncology-centered" model is largely adopted and established care pathways are still incomplete. Survivorship care needs to be put at the center of an educational policy and of a widespread organizational effort, directed at improving appropriateness and quality.

Many people diagnosed with haematologic malignancies are of child-bearing age. Typical treatment courses pose a high risk of infertility, and a lot of people affected by this are in the midst of starting or growing their families. Thus, it is crucial that they are well informed about fertility preservation options and can discuss these with an oncologist early on in the development of their treatment plans. Unfortunately, however, this does not always happen. One hundred twenty oncologists from 37 German adult clinical facilities were surveyed regarding their discussions with young patients about fertility, family planning, and fertility preservation. Almost all of them said that they consider fertility preservation to be an important issue. They also reported several factors as having an influence on the likelihood and practicability of discussing these subjects. Most knew about the existence of cryoconservation of germ cells and the use of GnRH analogues (95 %), but only half of them claimed to have a thorough understanding of these options. Many said they would like to learn more about this and that informational brochures could be helpful. Even though many oncologists do have good working knowledge of the subject, patients of reproductive age are not yet consistently given comprehensive information about the options available to them. To improve oncologists' knowledge of reproductive medicine, cooperation with fertility specialists should be facilitated, and informational leaflets should be made available both to patients and their medical care providers.

The diffusion of genomic testing is critical to the success of precision medicine, but there is limited information on oncologists' uptake of genetic technology. We aimed to assess the frequency with which medical oncologists and surgeons order BRCA 1/2 and Oncotype DX testing for breast cancer patients. We surveyed 732 oncologists and surgeons treating breast cancer patients. Physicians were from Florida, New York, New Jersey, and Pennsylvania, and were listed in the 2010 AMA Masterfile or identified by patients. 80.6% of providers ordered BRCA 1/2 testing at least sometimes and 85.4% ordered Oncotype DX (p = 0.01). More frequent ordering of BRCA 1/2 was associated with more positive attitudes toward genetic innovation (OR 1.14, p = 0.001), a belief that testing was likely to be covered by patients' insurance (OR 2.84, p < 0.001), and more frequent ordering of Oncotype DX testing (OR 8.69, p < 0.001). More frequent use of Oncotype DX was associated with a belief that testing was likely to be covered by insurance (OR 7.33, p < 0.001), as well as with more frequent ordering of BRCA 1/2 testing (OR 9.48, p < 0.001). Nearly one in five providers never or rarely ever ordered BRCA 1/2 testing for their breast cancer patients, and nearly 15% never or rarely ever ordered Oncotype DX. Less frequent ordering of BRCA 1/2 is associated with less frequent use of Oncotype DX testing, and vice versa. Those who do not order BRCA 1/2 testing report less positive attitudes toward genetic innovation. Further education of this subset of providers regarding the benefits of precision medicine may enable more rapid diffusion of genetic technology.

Purpose: To determine the employment status and location of recent Canadian radiation oncology (RO) graduates and to identify current workforce entry trends. Methods and Materials: A fill-in-the-blank spreadsheet was distributed to all RO program directors in December 2013 and June 2014, requesting the employment status and location of their graduates over the last 3 years. Visa trainee graduates were excluded. Results: Response rate from program directors was 100% for both survey administrations. Of 101 graduates identified, 99 (98%) had known employment status and location. In the December survey, 5 2013 graduates (16%), 17 2012 graduates (59%), and 18 2011 graduates (75%) hadmore » permanent staff employment. Six months later, 5 2014 graduates (29%), 15 2013 graduates (48%), 24 2012 graduates (83%), and 21 2011 graduates (88%) had secured staff positions. Fellowships and temporary locums were common for those without staff employment. The proportion of graduates with staff positions abroad increased from 22% to 26% 6 months later. Conclusions: Workforce entry for most RO graduates was delayed but showed steady improvement with longer time after graduation. High emigration rates for jobs abroad signify domestic employment challenges for newly certified, Canadian-trained radiation oncologists. Coordination on a national level is required to address and regulate radiation oncologist supply and demand disequilibrium in Canada.« less

[Guidelines for psychosocial care of cancer patients].

Caminiti, Caterina

2013-01-01

Guidelines for psychosocial care of cancer patients. The Italian Association of Medical Oncologists published in 2013 the update of the first edition of the Psychosocial Guidelines for the care of cancer patients. The guidelines, produced by a multidisciplinary group (medical doctors, nurses, oncologists, psychologists and patients) aim at recognizing the importance of psychosocial care in helping the patients and their relatives to overcome the effects of the diagnosis and the treatments on mental health and emotional wellbeing. In some cases the evidences available are not as hard as those supporting drug treatments: many outcomes such as the effectiveness of educational interventions, the patients' wellbeing, thrust, perception of support, for their nature and complexity require both quantitative and qualitative measurements. Lack of robust evidences such as those obtained from clinical trials, does not necessarily correspond to lack of effectiveness of the intervention nor should make us forget that patients' rights (to good care, information and support) should be guaranteed.

Future Supply and Demand for Oncologists : Challenges to Assuring Access to Oncology Services

Purpose To conduct a comprehensive analysis of supply of and demand for oncology services through 2020. This study was commissioned by the Board of Directors of ASCO. Methods New data on physician supply gathered from surveys of practicing oncologists, oncology fellows, and fellowship program directors were analyzed, along with 2005 American Medical Association Masterfile data on practicing medical oncologists, hematologists/oncologists, and gynecologic oncologists, to determine the baseline capacity and to forecast visit capacity through 2020. Demand for visits was calculated by applying age-, sex-, and time-from-diagnosis-visit rate data from the National Cancer Institute's analysis of the 1998 to 2002 Surveillance, Epidemiology and End Results (SEER) database to the National Cancer Institute's cancer incidence and prevalence projections. The cancer incidence and prevalence projections were calculated by applying a 3-year average (2000–2002) of age- and sex-specific cancer rates from SEER to the US Census Bureau population projections released on March 2004. The baseline supply and demand forecasts assume no change in cancer care delivery and physician practice patterns. Alternate scenarios were constructed by changing assumptions in the baseline models. Results Demand for oncology services is expected to rise rapidly, driven by the aging and growth of the population and improvements in cancer survival rates, at the same time the oncology workforce is aging and retiring in increasing numbers. Demand is expected to rise 48% between 2005 and 2020. The supply of services provided by oncologists during this time is expected to grow more slowly, approximately 14%, based on the current age distribution and practice patterns of oncologists and the number of oncology fellowship positions. This translates into a shortage of 9.4 to 15.0 million visits, or 2,550 to 4,080 oncologists—roughly one-quarter to one-third of the 2005 supply. The baseline projections do not include any alterations based on changes in practice patterns, service use, or cancer treatments. Various alternate scenarios were also developed to show how supply and demand might change under different assumptions. Conclusions ASCO, policy makers, and the public have major challenges ahead of them to forestall likely shortages in the capacity to meet future demand for oncology services. A multifaceted strategy will be needed to ensure that Americans have access to oncology services in 2020, as no single action will fill the likely gap between supply and demand. Among the options to consider are increasing the number of oncology fellowship positions, increasing use of nonphysician clinicians, increasing the role of primary care physicians in the care of patients in remission, and redesigning service delivery.

Advancement in academic radiation oncology is largely contingent on research productivity and the perceived external influence of an individual's scholarly work. The purpose of this study was to use the Hirsch index (h-index) to estimate the research productivity of current radiation oncology faculty at U.S. academic institutions between 1996 and 2007. We performed bibliometric citation database searches for available radiation oncology faculty at domestic residency-training institutions (n = 826). The outcomes analyzed included the total number of manuscripts, total number of citations, and the h-index between 1996 and 2007. Analysis of overall h-index rankings with stratification by academic ranking, junior vs. senior faculty status, and gender was performed. Of the 826 radiation oncologists, the mean h-index was 8.5. Of the individuals in the top 10% by the h-index, 34% were chairpersons, 88% were senior faculty, and 13% were women. A greater h-index was associated with a higher academic ranking and senior faculty status. Recursive partitioning analysis revealed an h-index threshold of 15 (p <0.0001) as an identified breakpoint between the senior and junior faculty. Overall, women had lower h-indexes compared with men (mean, 6.4 vs. 9.4); however, when stratified by academic ranking, the gender differential all but disappeared. Using the h-index as a partial surrogate for research productivity, it appears that radiation oncologists in academia today comprise a prolific group, however, with a highly skewed distribution. According to the present analysis, the h-index correlated with academic ranking. Thus, it potentially has utility in the process of promotion decisions. Overall, women in radiation oncology were less academically productive than men; the possible reasons for the gender differential are discussed.

The purpose of this study was to evaluate, during a national workshop, the inter-observer variability in target volume delineation for primary extremity soft tissue sarcoma radiation therapy. Six expert sarcoma radiation oncologists (members of French Sarcoma Group) received two extremity soft tissue sarcoma radiation therapy cases 1: one preoperative and one postoperative. They were distributed with instructions for contouring gross tumour volume or reconstructed gross tumour volume, clinical target volume and to propose a planning target volume. The preoperative radiation therapy case was a patient with a grade 1 extraskeletal myxoid chondrosarcoma of the thigh. The postoperative case was a patient with a grade 3 pleomorphic undifferentiated sarcoma of the thigh. Contour agreement analysis was performed using kappa statistics. For the preoperative case, contouring agreement regarding GTV, gross tumour volume GTV, clinical target volume and planning target volume were substantial (kappa between 0.68 and 0.77). In the postoperative case, the agreement was only fair for reconstructed gross tumour volume (kappa: 0.38) but moderate for clinical target volume and planning target volume (kappa: 0.42). During the workshop discussion, consensus was reached on most of the contour divergences especially clinical target volume longitudinal extension. The determination of a limited cutaneous cover was also discussed. Accurate delineation of target volume appears to be a crucial element to ensure multicenter clinical trial quality assessment, reproducibility and homogeneity in delivering RT. radiation therapy RT. Quality assessment process should be proposed in this setting. We have shown in our study that preoperative radiation therapy of extremity soft tissue sarcoma has less inter-observer contouring variability.

This investigation examined factors affecting patient involvement in consultations to decide local treatment for early breast cancer and the effectiveness of two methods of preconsultation education aimed at increasing patient participation in these discussions. Sixty patients with Stage I or II breast cancer (1) were pretested on their knowledge about breast cancer treatment and optimism for the future, (2) were randomly assigned to one of two methods for preconsultation education: interactive multimedia program or brochure, (3) completed knowledge and optimism measures, (4) consulted with a medical oncologist, radiation oncologist, and general surgeon, and (5) completed self-report measures assessing their involvement in the consultations and control over decision-making. The consultations were audiorecorded and analyzed to identify behavioral indicators of patient involvement (question-asking, opinion-giving, and expressing concern) and physician utterances encouraging patient participation. College-educated patients younger than 65 years of age were more active participants in these consultations than were older, less educated patients. In addition, patients showed more involvement when they interacted with physicians who encouraged and facilitated patient participation. The method of education did not affect patient involvement although patients tended to learn more about breast cancer treatment after using the multimedia program than after reading the brochure. Although patients vary in their expressiveness, physicians may be able to increase patient participation in deciding treatment by using patient-centered behavior. Also, preconsultation education appears to be an effective clinical strategy for helping patients gain an accurate understanding of their treatment options before meeting with physicians.

In recent years, the number of oral anticancer drugs used in clinical practice has rapidly increased. The Italian Society of Medical Oncology (AIOM) conducted a survey to describe the impact of the use of oral anticancer drugs on the daily activity of Italian oncology practices. A survey questionnaire was distributed to the coordinators of the regional sections of AIOM. A 6-month period was considered, from January 1, 2010 to June 30, 2010. The survey addressed (1) quantitative aspects of the use of oral anticancer drugs; (2) practical aspects in the management of patients treated with these drugs; (3) issues related to treatment costs and reimbursement procedures. Thirty-six questionnaires were received from institutions distributed throughout the Italian territory. Oral anticancer drugs (both chemotherapy and molecularly targeted agents) accounted for a significant proportion (17%) of prescribed treatments. Among the responding institutions, there were different dispensation procedures of oral drugs to patients: drugs were dispensed by the pharmacist (57%) or directly by the medical oncologist (23%) or nurse (20%). The medical oncologist played a major role in the communication with patients (73% alone and a further 24% in cooperation with other professional figures) and was the point of reference in the event of side effects in 97% of cases. In most cases, the reimbursement of drug costs was separated ("File F" procedure) from the flat fare received by the hospital for outpatient visits or day-hospital access. Optimal organization of oral anticancer treatment warrants the cooperation and integration of multiple professional figures. At least three figures are involved in patient management in the hospital: the medical oncologist, the nurse, and the hospital pharmacist. Oral anticancer treatments are associated with specific reimbursement issues: in the majority of cases, the cost of the drug is reimbursed separately from the cost of patient access.

As cancer therapy becomes more successful and cancer survival rates increase, the dentist will be treating more patients who have received radiation therapy for head and neck cancer. Occasionally, patients and health professionals have indicated a belief that patients who have received irradiation to the head and neck regions should not be subjected to additional radiation through dental diagnostic X-ray exposures. A literature search failed to find any references that specifically addressed this question.

A group from Texas Oncology and Baylor Charles A. Sammons Cancer Center traveled to Huê´, Vietnam, as part of Health Volunteers Overseas. From February 21 to March 6, 2012, five Baylor Sammons medical oncologists and an oncology nurse worked with a medical oncologist and a surgeon at the Huê´ College of Medicine and Pharmacy, suggesting approaches based on available resources. The two groups worked together to find optimal solutions for the patients. What stood out the most for the Baylor Sammons group was the Huê´ team's remarkable work ethic, empathy for patients, and treatment resourcefulness. The Baylor Sammons group also identified several unmet needs that could potentially be addressed by future volunteers in Huê´, including creation of an outpatient hospice program, establishment of breast cancer screening, modernization of the pathology department, instruction in and better utilization of pain management, better use of clinic space, and the teaching of oncology and English to medical students. There was a mutual exchange of knowledge between the two medical teams. The Baylor Sammons group not only taught but also learned how to take good care of patients with limited resources.

To examine how communication about life expectancy is initiated in consultations about palliative chemotherapy, and what prognostic information is presented. Patients with advanced cancer (n=41) with a median life expectancy <1year and oncologists (n=6) and oncologists-in-training (n=7) meeting with them in consultations (n=62) to discuss palliative chemotherapy were included. Verbatim transcripts of audio-recorded consultations were analyzed using MAXqda10. Life expectancy was addressed in 19 of 62 of the consultations. In all cases, patients took the initiative, most often through direct questions. Estimates were provided in 12 consultations in various formats: the likelihood of experiencing a significant event, point estimates or general time scales of "months to years", often with an emphasis on the "years". The indeterminacy of estimates was consistently stressed. Also their potential inadequacy was regularly addressed, often by describing beneficial prognostic predictors for the specific patient. Oncologists did not address the reliability or precision of estimates. Oncologists did not initiate talk about life expectancy, they used different formats, emphasized the positive and stressed unpredictability, yet not ambiguity of estimates. Prognostic communication should be part of the medical curriculum. Further research should address the effect of different formats of information provision. Copyright © 2017 Elsevier B.V.

The ongoing structure of radiation oncology in Japan in terms of equipment, personnel, patient load and geographic distribution was evaluated in order to radiation identify and improve any deficiencies. A questionnaire-based national structure survey was conducted from March 2010 to January 2011 by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO). These data were analyzed in terms of the institutional stratification of the Patterns of Care Study (PCS). The total numbers of new cancer patients and total of cancer patients (new and repeat) treated with radiation in 2009 were estimated at 201,000 and 240,000, respectively. The type and numbers of systems in actual use consisted of Linac (816), telecobalt (9), Gamma Knife (46), (60)Co remote afterloading system (RALS) (29) and (192)Ir RALS systems (130). The Linac systems used dual energy function for 586 (71.8%), 3DCRT for 663 (81.3%) and IMRT for 337 units (41.3%). There were 529 JASTRO-certified radiation oncologists (ROs), 939.4 full-time equivalent (FTE) ROs, 113.1 FTE medical physicists and 1836 FTE radiation therapists. The frequency of interstitial radiation therapy use for prostate and of intensity-modulated radiotherapy increased significantly. PCS stratification can clearly identify the maturity of structures based on their academic nature and caseload. Geographically, the more JASTRO-certified physicians there were in a given area, the more radiation therapy tended to be used for cancer patients. In conclusion, the Japanese structure has clearly improved during the past 19 years in terms of equipment and its use, although a shortage of manpower and variations in maturity disclosed by PCS stratification remained problematic in 2009.

IMPORTANCE Observational studies demonstrate links between patient-centered communication, quality of life (QOL), and aggressive treatments in advanced cancer, yet few randomized clinical trials (RCTs) of communication interventions have been reported. OBJECTIVE To determine whether a combined intervention involving oncologists, patients with advanced cancer, and caregivers would promote patient-centered communication, and to estimate intervention effects on shared understanding, patient-physician relationships, QOL, and aggressive treatments in the last 30 days of life. DESIGN, SETTING, AND PARTICIPANTS Cluster RCT at community- and hospital-based cancer clinics in Western New York and Northern California; 38 medical oncologists (mean age 44.6 years; 11 (29%) female) and 265 community-dwelling adult patients with advanced nonhematologic cancer participated (mean age, 64.4 years, 146 [55.0%] female, 235 [89%] white; enrolled August 2012 to June 2014; followed for 3 years); 194 patients had participating caregivers. INTERVENTIONS Oncologists received individualized communication training using standardized patient instructors while patients received question prompt lists and individualized communication coaching to identify issues to address during an upcoming oncologist visit. Both interventions focused on engaging patients in consultations, responding to emotions, informing patients about prognosis and treatment choices, and balanced framing of information. Control participants received no training. MAIN OUTCOMES AND MEASURES The prespecified primary outcome was a composite measure of patient-centered communication coded from audio recordings of the first oncologist visit following patient coaching (intervention group) or enrollment (control). Secondary outcomes included the patient-physician relationship, shared understanding of prognosis, QOL, and aggressive treatments and hospice use in the last 30 days of life. RESULTS Data from 38 oncologists (19 randomized to intervention) and 265 patients (130 intervention) were analyzed. In fully adjusted models, the intervention resulted in clinically and statistically significant improvements in the primary physician-patient communication end point (adjusted intervention effect, 0.34; 95% CI, 0.06–0.62; P = .02). Differences in secondary outcomes were not statistically significant. CONCLUSIONS AND RELEVANCE A combined intervention that included oncologist communication training and coaching for patients with advanced cancer was effective in improving patient-centered communication but did not affect secondary outcomes.

The ProtecT trial has provided level 1 evidence supporting active surveillance for prostate cancer patients with low-risk and intermediate-risk disease. The effect of these findings on the opinions of North American genitourinary (GU) experts regarding the role of active surveillance for these patients has not been previously examined. A survey was distributed to 88 practicing North American GU physicians serving on decision-making committees of cooperative group research organizations. Questions pertained to appropriateness of active surveillance in patients with low-risk and intermediate-risk (Gleason 3+4) disease. Opinions regarding active surveillance were correlated with practice patterns using Fisher exact test. Forty-two radiation oncologists completed the survey. Forty percent had been in practice for more than 20 years; 90% practice at an academic center. Forty-five percent see ≥ 20 patients per month in consultation. More than 95% (40 of 42) recommended active surveillance for Gleason 6 disease, whereas only 17% recommended active surveillance for Gleason 3+4 disease. There were no demographic differences between supporters or opponents regarding active surveillance with regard to monthly patient volume, practice type, likelihood of self-identifying as an expert brachytherapist, belief in advanced imaging techniques, or preferred default external beam radiation therapy dose/fractionation for either low-risk or intermediate-risk disease. However, there was a trend toward greater support of active surveillance for Gleason 3+4 disease among experts having practiced < 10 years versus ≥ 10 years (P = .085). Active surveillance is almost universally supported by North American GU expert radiation oncologists for low-risk prostate cancer. However, there is very weak support for this strategy in Gleason 3+4 disease despite the ProtecT trial providing level 1 evidentiary support in both risk groups. There were no significant differences between experts supporting versus opposing active surveillance for either low-risk or intermediate-risk disease. These preferences might affect the design of future clinical studies, influencing the adoption of active surveillance in North American clinical practice. Copyright © 2017 Elsevier Inc.

To evaluate inter- and intra-observer variability in gross tumor volume definition for adult limb/trunk soft tissue sarcomas. Imaging studies of 15 patients previously treated with preoperative radiation were used in this study. Five physicians (radiation oncologists, orthopedic surgeons and a musculoskeletal radiologist) were asked to contour each of the 15 tumors on T1-weighted, gadolinium-enhanced magnetic resonance images. These contours were drawn twice by each physician. The volume and center of mass coordinates for each gross tumor volume were extracted and a Boolean analysis was performed to measure the degree of volume overlap. The median standard deviation in gross tumor volumes across observers was 6.1% of the average volume (range: 1.8%-24.9%). There was remarkably little variation in the 3D position of the gross tumor volume center of mass. For the 15 patients, the standard deviation of the 3D distance between centers of mass ranged from 0.06 mm to 1.7 mm (median 0.1mm). Boolean analysis demonstrated that 53% to 90% of the gross tumor volume was common to all observers (median overlap: 79%). The standard deviation in gross tumor volumes on repeat contouring was 4.8% (range: 0.1-14.4%) with a standard deviation change in the position of the center of mass of 0.4mm (range: 0mm-2.6mm) and a median overlap of 93% (range: 73%-98%). Although significant inter-observer differences were seen in gross tumor volume definition of adult soft-tissue sarcoma, the center of mass of these volumes was remarkably consistent. Variations in volume definition did not correlate with tumor size. Radiation oncologists should not hesitate to review their contours with a colleague (surgeon, radiologist or fellow radiation oncologist) to ensure that they are not outliers in sarcoma gross tumor volume definition. Protocols should take into account variations in volume definition when considering tighter clinical target volumes. Copyright © 2011 Société française de radiothérapie oncologique (SFRO).

Wang Dian, E-mail: dwang@mcw.edu; Bosch, Walter; Kirsch, David G.

Purpose: To evaluate variability in the definition of preoperative radiotherapy gross tumor volume (GTV) and clinical target volume (CTV) delineated by sarcoma radiation oncologists. Methods and Materials: Extremity sarcoma planning CT images along with the corresponding diagnostic MRI from two patients were distributed to 10 Radiation Therapy Oncology Group sarcoma radiation oncologists with instructions to define GTV and CTV using standardized guidelines. The CT data with contours were then returned for central analysis. Contours representing statistically corrected 95% (V95) and 100% (V100) agreement were computed for each structure. Results: For the GTV, the minimum, maximum, mean (SD) volumes (mL) weremore » 674, 798, 752 {+-} 35 for the lower extremity case and 383, 543, 447 {+-} 46 for the upper extremity case. The volume (cc) of the union, V95 and V100 were 882, 761, and 752 for the lower, and 587, 461, and 455 for the upper extremity, respectively. The overall GTV agreement was judged to be almost perfect in both lower and upper extremity cases (kappa = 0.9 [p < 0.0001] and kappa = 0.86 [p < 0.0001]). For the CTV, the minimum, maximum, mean (SD) volumes (mL) were 1145, 1911, 1605 {+-} 211 for the lower extremity case and 637, 1246, 1006 {+-} 180 for the upper extremity case. The volume (cc) of the union, V95, and V100 were 2094, 1609, and 1593 for the lower, and 1533, 1020, and 965 for the upper extremity cases, respectively. The overall CTV agreement was judged to be almost perfect in the lower extremity case (kappa = 0.85 [p < 0.0001]) but only substantial in the upper extremity case (kappa = 0.77 [p < 0.0001]). Conclusions: Almost perfect agreement existed in the GTV of these two representative cases. Tshere was no significant disagreement in the CTV of the lower extremity, but variation in the CTV of upper extremity was seen, perhaps related to the positional differences between the planning CT and the diagnostic MRI.« less

Background The fast growing demand and the shortage of resources are pushing toward more efficient models of survivorship care delivery. The Associazione Italiana di Oncologia Medica (AIOM) established an interdisciplinary working group with the purpose of promoting organizational improvements at the national level. A survey aimed at assessing attitudes and feelings of oncologists was considered preliminary to further initiatives. Methods A 25-item questionnaire, sent to the mailing list of the Society, explored the following issues on the practice of breast and colorectal cancer patients' follow up: 1) organization; 2) clinical features; 3) feelings about the different meanings of follow-up. Results Ninety-one oncologists of 160 institutions (57%) answered to the questionnaire. Although follow up is considered a distinct oncological activity in 68%, a fully shared organization between specialists is not common and communications with Primary Care Physicians are not structured in the majority of the cases. Fifty-five and 30% of the oncologists follow breast and colorectal cancer patients indefinitely. In case of discharge a survivorship care plan is delivered in only 9%. The majority of respondents do not hold a role of follow up in mortality reduction. Conclusions Although survivorship care represents a significant part of the oncologists' workload, an “oncology-centered” model is largely adopted and established care pathways are still incomplete. Survivorship care needs to be put at the center of an educational policy and of a widespread organizational effort, directed at improving appropriateness and quality. PMID:24983237

Understanding how physicians acquire and adopt new technologies for cancer diagnosis and treatment is poorly understood, yet is critical to the dissemination of evidence-based practices. Sentinel lymph node biopsy (SLNB) has recently become a standard technique for axillary staging in early breast cancer and is an ideal platform for studying medical technology diffusion. We sought to describe the timing of SLNB adoption and patterns of surgeon interactions with the following educational sources: local university training program, surgical literature, national meetings/courses, national specialty centers, and other local surgeons. A cross-sectional survey that used semistructured interviews was used to assess timing of adoption, practice patterns, and learning sources for SLNB among surgical oncologists and general surgeons in a single metropolitan area. A total of 44 eligible surgeons were identified; 38 (86%) participated. All surgical oncologists (11 of 11) and most general surgeons (26 of 27) had implemented SLNB. Surgical oncologists were older (mean 51 vs. 48 years, P = .02) and had used SLNB longer (6.1 vs. 3.3 years, P = .01) than general surgeons. By use of social network diagrams, surgical oncologists and the university training program were shown to be key intermediaries between general surgeons and national specialty centers. Surgeons in group practice tended to use more learning sources than solo practitioners. Surgical oncologists and university-based surgeons play key educational roles in disseminating new cancer treatments and therefore have a professional responsibility to educate other community physicians to increase the use of the most current, evidence-based practices.

Global Pattern of Nasopharyngeal Cancer: Correlation of Outcome With Access to Radiation Therapy

Lam, Ka-On; Lee, Anne W.M., E-mail: annelee@hku-szh.org; Choi, Cheuk-Wai

Purpose: This study aimed to estimate the treatment outcome of nasopharyngeal cancer (NPC) across the world and its correlation with access to radiation therapy (RT). Methods and Materials: The age-standardized mortality (ASM) and age-standardized incidence (ASI) rates of NPC from GLOBOCAN (2012) were summarized, and [1−(ASM/ASI)] was computed to give the proxy relative survival (RS). Data from the International Atomic Energy Agency (IAEA) and the World Bank were used to assess the availability of RT in surrogate terms: the number of RT equipment units and radiation oncologists per million population. Results: A total of 112 countries with complete valid datamore » were analyzed, and the proxy RS varied widely from 0% to 83% (median, 50%). Countries were categorized into Good, Median, and Poor outcome groups on the basis of their proxy RS (<45%, 45%-55%, and >55%). Eighty percent of new cases occurred in the Poor outcome group. Univariable linear regression showed a significant correlation between outcome and the availability of RT: proxy RS increased at 3.4% (P<.001) and 1.5% (P=.001) per unit increase in RT equipment and oncologist per million population, respectively. The median number of RT equipment units per million population increased significantly from 0.5 in the Poor, to 1.5 in the Median, to 4.6 in the Good outcome groups, and the corresponding number of oncologists increased from 1.1 to 3.3 to 7.1 (P<.001). Conclusions: Nasopharyngeal cancer is a highly treatable disease, but the outcome varies widely across the world. The current study shows a significant correlation between survival and access to RT based on available surrogate indicators. However, the possible reasons for poor outcome are likely to be multifactorial and complex. Concerted international efforts are needed not only to address the fundamental requirement for adequate RT access but also to obtain more comprehensive and accurate data for research to improve cancer outcome.« less

2016-10-01

Recent randomized trials have led to decreased use of completion axillary lymph node dissection (ALND) in early-stage breast cancer patients with a positive sentinel lymph node (SLN), causing controversy surrounding radiotherapy coverage of the axilla. We investigated the practice variation among radiation oncologists for regional nodal coverage for clinicopathologic scenarios and evaluated axillary field design decision-making processes. A customized, web-based questionnaire was e-mailed to 983 community (n = 617) and academic (n = 366) radiation oncologists with a breast cancer subspecialty practicing in the United States. The survey consisted of 18 multiple-choice questions evaluating general clinical preferences surrounding radiation therapy (RT) field design for patients with early-stage breast cancer and a positive SLN. Seven case scenarios were developed to investigate the field design in the setting of specific clinical and pathologic risk factors. Nodal coverage was classified as standard tangents (STs), high tangents (HTs), STs and a supraclavicular field (SCF), or STs and full axillary coverage (AX). A total of 145 evaluable responses were collected, with a response rate of 15.0%. Of the respondents, 12 (8.3%) reported using completion ALND for patients with 1 to 3 positive SLNs without extracapsular extension (ECE) and 66 (45.5%) performed ALND with 1 to 3 positive SLNs with ECE. For micrometastatic SLNs, with no lymphovascular system invasion, 115 (87.1%) used STs or HTs. The use of neoadjuvant chemotherapy (NAC) influenced RT field design for patients with a positive SLN without ECE, with 64 (48.5%) using STs and SCF or STs and AX treatment without NAC and 94 (70.7%) using SCF and AX after NAC. With macrometastatic SLN involvement, most respondents preferred SCF (45.27%) and AX (45.66%). In contrast, for micrometastatic involvement, HTs (43.61%) were frequently chosen. Forty (27.8%) reported using online predictive nomograms to predict further axillary involvement, with no difference between the academic and community radiation oncologists (P = .11). In SLN biopsy-positive early-stage breast cancer with omission of completion ALND, axillary RT is increasing used to cover the undissected axilla. Most respondents use SCF or AX for patients with low to intermediate pathologic features. Online prediction nomograms are used by a few practitioners to assist in clinical decision-making in this setting. Copyright © 2016 Elsevier Inc. All rights reserved.

Skin sparing mastectomy, a surgical procedure sparing a large portion of the overlying skin of the breast, and nipple-sparing mastectomy, sparing the whole nipple-areolar complex, are increasingly used, although their oncologic efficacy remains unclear. The aim of this study was to assess the radiation oncologists' opinions regarding the indications of radiation therapy (RT) after skin-sparing mastectomy and nipple-sparing mastectomy. Radiation oncology members of four national and international societies were invited to complete a questionnaire comprising of 22 questions to assess their opinions regarding RT indications in the context of skin-sparing and nipple-sparing mastectomy. A total of 298 radiation oncologists answered the questionnaire. 90.9% of respondents affirmed that breast cancer is one of their specializations. The majority declared that post-mastectomy RT is indicated for early-stage (stages I and II) breast cancer patients who present with risk factors for recurrence after skin-sparing or nipple-sparing mastectomy (87.2% and 80.2%, respectively). All suggested risk factors (tumor size, lymph node involvement, extracapsular extension, lymphovascular space invasion, positive surgical margins, triple negative tumor, multicentric tumor, and age) were considered as major elements (important or very important). There is no consensus regarding the necessity of evaluating residual breast tissue or the definition of residual breast tissue after mastectomy. All classic factors were considered as major elements, potentially influencing the decision to advice or not postoperative RT. Many uncertainties remain about the indications for RT after skin-sparing mastectomy or nipple-sparing mastectomy. © 2016 Wiley Periodicals, Inc.

To evaluate the delivery costs, using time-driven activity-based costing, and reimbursement for definitive radiation therapy for locally advanced cervical cancer. Process maps were created to represent each step of the radiation treatment process and included personnel, equipment, and consumable supplies used to deliver care. Personnel were interviewed to estimate time involved to deliver care. Salary data, equipment purchasing information, and facilities costs were also obtained. We defined the capacity cost rate (CCR) for each resource and then calculated the total cost of patient care according to CCR and time for each resource. Costs were compared with 2016 Medicare reimbursement and relative value units (RVUs). The total cost of radiation therapy for cervical cancer was $12,861.68, with personnel costs constituting 49.8%. Brachytherapy cost $8610.68 (66.9% of total) and consumed 423 minutes of attending radiation oncologist time (80.0% of total). External beam radiation therapy cost $4055.01 (31.5% of total). Personnel costs were higher for brachytherapy than for the sum of simulation and external beam radiation therapy delivery ($4798.73 vs $1404.72). A full radiation therapy course provides radiation oncologists 149.77 RVUs with intensity modulated radiation therapy or 135.90 RVUs with 3-dimensional conformal radiation therapy, with total reimbursement of $23,321.71 and $16,071.90, respectively. Attending time per RVU is approximately 4-fold higher for brachytherapy (5.68 minutes) than 3-dimensional conformal radiation therapy (1.63 minutes) or intensity modulated radiation therapy (1.32 minutes). Time-driven activity-based costing was used to calculate the total cost of definitive radiation therapy for cervical cancer, revealing that brachytherapy delivery and personnel resources constituted the majority of costs. However, current reimbursement policy does not reflect the increased attending physician effort and delivery costs of brachytherapy. We hypothesize that the significant discrepancy between treatment costs and physician effort versus reimbursement may be a potential driver of reported national trends toward poor compliance with brachytherapy, and we suggest re-evaluation of payment policies to incentivize quality care.

We report on experience and insights gained from prototyping, for clinical radiation oncologists, a new access tool for the University of Washington Digital Anatomist information resources. This access tool is designed to integrate with a radiation therapy planning (RTP) system in use in a clinical setting. We hypothesize that the needs of practitioners in a clinical setting are different from the needs of students, the original targeted users of the Digital Anatomist system, but that a common knowledge resource can serve both. Our prototype was designed to help define those differences and study the feasibility of a full anatomic reference system that will support both clinical radiation therapy and all the existing educational applications.

Radiation-Induced Oral Mucositis

2017-01-01

Radiation-induced oral mucositis (RIOM) is a major dose-limiting toxicity in head and neck cancer patients. It is a normal tissue injury caused by radiation/radiotherapy (RT), which has marked adverse effects on patient quality of life and cancer therapy continuity. It is a challenge for radiation oncologists since it leads to cancer therapy interruption, poor local tumor control, and changes in dose fractionation. RIOM occurs in 100% of altered fractionation radiotherapy head and neck cancer patients. In the United Sates, its economic cost was estimated to reach 17,000.00 USD per patient with head and neck cancers. This review will discuss RIOM definition, epidemiology, impact and side effects, pathogenesis, scoring scales, diagnosis, differential diagnosis, prevention, and treatment. PMID:28589080

SlicerRT: radiation therapy research toolkit for 3D Slicer.

2012-10-01

Interest in adaptive radiation therapy research is constantly growing, but software tools available for researchers are mostly either expensive, closed proprietary applications, or free open-source packages with limited scope, extensibility, reliability, or user support. To address these limitations, we propose SlicerRT, a customizable, free, and open-source radiation therapy research toolkit. SlicerRT aspires to be an open-source toolkit for RT research, providing fast computations, convenient workflows for researchers, and a general image-guided therapy infrastructure to assist clinical translation of experimental therapeutic approaches. It is a medium into which RT researchers can integrate their methods and algorithms, and conduct comparative testing. SlicerRT was implemented as an extension for the widely used 3D Slicer medical image visualization and analysis application platform. SlicerRT provides functionality specifically designed for radiation therapy research, in addition to the powerful tools that 3D Slicer offers for visualization, registration, segmentation, and data management. The feature set of SlicerRT was defined through consensus discussions with a large pool of RT researchers, including both radiation oncologists and medical physicists. The development processes used were similar to those of 3D Slicer to ensure software quality. Standardized mechanisms of 3D Slicer were applied for documentation, distribution, and user support. The testing and validation environment was configured to automatically launch a regression test upon each software change and to perform comparison with ground truth results provided by other RT applications. Modules have been created for importing and loading DICOM-RT data, computing and displaying dose volume histograms, creating accumulated dose volumes, comparing dose volumes, and visualizing isodose lines and surfaces. The effectiveness of using 3D Slicer with the proposed SlicerRT extension for radiation therapy research was demonstrated on multiple use cases. A new open-source software toolkit has been developed for radiation therapy research. SlicerRT can import treatment plans from various sources into 3D Slicer for visualization, analysis, comparison, and processing. The provided algorithms are extensively tested and they are accessible through a convenient graphical user interface as well as a flexible application programming interface.

Cranial Stereotactic Radiosurgery: Current Status of the Initial Paradigm Shifter

PubMed Central

Sheehan, Jason P.; Yen, Chun-Po; Lee, Cheng-Chia; Loeffler, Jay S.

2014-01-01

The concept of stereotactic radiosurgery (SRS) was first described by Lars Leksell in 1951. It was proposed as a noninvasive alternative to open neurosurgical approaches to manage a variety of conditions. In the following decades, SRS emerged as a unique discipline involving a collegial partnership among neurosurgeons, radiation oncologists, and medical physicists. SRS relies on the precisely guided delivery of high-dose ionizing radiation to an intracranial target. The focused convergence of multiple beams yields a potent therapeutic effect on the target and a steep dose fall-off to surrounding structures, thereby minimizing the risk of collateral damage. SRS is typically administered in a single session but can be given in as many as five sessions or fractions. By providing an ablative effect noninvasively, SRS has altered the treatment paradigms for benign and malignant intracranial tumors, functional disorders, and vascular malformations. Literature on extensive intracranial radiosurgery has unequivocally demonstrated the favorable benefit-to-risk profile that SRS affords for appropriately selected patients. In a departure from conventional radiotherapeutic strategies, radiosurgical principles have recently been extended to extracranial indications such as lung, spine, and liver tumors. The paradigm shift resulting from radiosurgery continues to alter the landscape of related fields. PMID:25113762

Medical decision-making capacity is a higher-order functional skill that refers to a patient's ability to make informed, sound decisions related to care and treatment. In a medical context, understanding is the most cognitively demanding consent standard and refers to a patient's ability to comprehend information to the extent that informed decisions can be made. The association between reasoning and cognition was examined using data from 41 patients with diagnosed brain metastasis. All diagnoses were made by a board-certified radiation oncologist and were verified histologically. In total, 41 demographically matched, cognitively healthy controls were also included to aid in classifying patients with brain metastasis according to reasoning status (ie, intact or impaired). Results indicate that measures of simple attention, verbal fluency, verbal memory, processing speed, and executive functioning were all associated with understanding, and that verbal memory and phonemic fluency were the primary cognitive predictors. Using these two primary predictors, equations can be constructed to predict the ability to understand treatment decisions in patients with brain metastasis. Although preliminary, these data demonstrate how cognitive measures can estimate understanding as it relates to medical decision-making capacities in these patients. Clinically, these findings suggest that poor verbal memory and expressive language function could serve as "red flags" for reduced consent capacity in this patient population, thus signaling that a more comprehensive medical decision-making capacity evaluation is warranted. © 2015 American Cancer Society.

Socioeconomic and Clinical Factors Are Key To Uncovering Disparity in Accrual Onto Therapeutic Trials for Breast Cancer

To monitor and address disparity in accrual, patient participation in cancer clinical trials is routinely summarized by race/ethnicity. To investigate whether confounding obscures racial/ethnic disparity in participation, all women with breast cancer treated by medical oncologists at City of Hope Comprehensive Cancer Center from 2004 through 2009 were classified by birthplace and self-reported race/ethnicity, and followed for accrual onto therapeutic trials through 2010. Undetectable on univariate analysis, significantly reduced participation by subjects of African, Asian, Eastern European, Latin American, and Middle Eastern ancestries was revealed after accounting for age, socioeconomic factors, tumor and oncologist characteristics, and intrapractice clustering of patients.

Epidemiology of breast cancer in Malaysia.

Yip, Cheng Har; Taib, Nur Aishah Mohd; Mohamed, Ibraham

2006-01-01

Data from the National Cancer Registry of Malaysia for 2004 provide an age-standardised incidence rate (ASR) of 46.2 per 100,000 women. This means that approximately 1 in 20 women in the country develop breast cancer in their lifetime. However, the rate differs between the three main races, the Malays, Chinese and Indians. The age standardized incidence in Chinese is the highest, with 59.7 per 100,000, followed by the Indians at 55.8 per 100,000. The Malays have the lowest incidence of 33.9 per 100,000. This translates into 1 in 16 Chinese, 1 in 16 Indian and 1 in 28 Malay women developing breast cancer at some stage in their lives. The commonest age at presentation is between 40-49 years, with just over 50% of the cases under the age of 50 years, 16.8% below 40, and 2% under 30. Some 55.7% of all cases were found to be ER positive. The commonest presenting symptom was a lump in the breast in over 90% of cases, generally felt by the woman herself. The mean size of the lump was 4.2 cm, and on average, the women waited 3 months before seeking medical attention. Over the 12-year period from 1993 to 2004, about 60-70% of women presented with early stage (Stages 1-2) while 30-40% presented with late breast cancer (Stages 3-4). Especially Malays present at later stages and with larger tumours. Consequently their survival is worse than with Chinese and Indian women. The challenge in Malaysia is to be able to provide a comprehensive service in the diagnosis and treatment of breast cancer, and this requires training of a team of health professionals dedicated to breast health, such as breast surgeons, radiologists specializing in breast imaging, breast pathologists, plastic surgeons specializing in breast reconstruction, medical and radiation oncologists, psycho-oncologists, counselors, and breast nurses. Advocacy can play a role here in galvanizing the political will to meet this challenge.

Improved understanding of risk of recurrence (ROR) is needed to reduce cases of recurrence and more effectively treat breast cancer patients. The purpose of this study was to examine how a gene-expression profile (GEP), identified by Prosigna, influences physician adjuvant treatment selection for early breast cancer (EBC) and the effects of this influence on optimizing adjuvant treatment recommendations in clinical practice. A prospective, observational, multicenter study was carried out in 15 hospitals across Spain. Participating medical oncologists completed pre-assessment, post-assessment, and follow-up questionnaires recording their treatment recommendations and confidence in these recommendations, before and after knowing the patient's ROR. Patients completed questionnaires on decision-making, anxiety, and health status. Between June 2013 and January 2014, 217 patients enrolled and a final 200 were included in the study. Patients were postmenopausal, estrogen receptor positive, human epidermal growth hormone factor negative, and node negative with either stage 1 or stage 2 tumors. After receiving the GEP results, treatment recommendations were changed for 40 patients (20%). The confidence of medical oncologists in their treatment recommendations increased in 41.6% and decreased in 6.5% of total cases. Patients reported lower anxiety after physicians made treatment recommendations based on the GEP results (p < 0.05). Though this study does not include evaluation of the impact of GEP on long-term outcomes, it was found that GEP results influenced the treatment decisions of medical oncologists and their confidence in adjuvant therapy selection. Patients' anxiety about the selected adjuvant therapy decreased with use of the GEP.

Pohar, Surjeet, E-mail: spohar@iuhealth.org; Fung, Claire Y.; Hopkins, Shane

Purpose: The American Society for Radiation Oncology (ASTRO) conducted the 2012 Radiation Oncology Workforce Survey to obtain an up-to-date picture of the workforce, assess its needs and concerns, and identify quality and safety improvement opportunities. The results pertaining to radiation oncologists (ROs) and residents (RORs) are presented here. Methods: The ASTRO Workforce Subcommittee, in collaboration with allied radiation oncology professional societies, conducted a survey study in early 2012. An online survey questionnaire was sent to all segments of the radiation oncology workforce. Respondents who were actively working were included in the analysis. This manuscript describes the data for ROs andmore » RORs. Results: A total of 3618 ROs and 568 RORs were surveyed. The response rate for both groups was 29%, with 1047 RO and 165 ROR responses. Among ROs, the 2 most common racial groups were white (80%) and Asian (15%), and the male-to-female ratio was 2.85 (74% male). The median age of ROs was 51. ROs averaged 253.4 new patient consults in a year and 22.9 on-treatment patients. More than 86% of ROs reported being satisfied or very satisfied overall with their career. Close to half of ROs reported having burnout feelings. There was a trend toward more frequent burnout feelings with increasing numbers of new patient consults. ROs' top concerns were related to documentation, reimbursement, and patients' health insurance coverage. Ninety-five percent of ROs felt confident when implementing new technology. Fifty-one percent of ROs thought that the supply of ROs was balanced with demand, and 33% perceived an oversupply. Conclusions: This study provides a current snapshot of the 2012 radiation oncology physician workforce. There was a predominance of whites and men. Job satisfaction level was high. However a substantial fraction of ROs reported burnout feelings. Perceptions about supply and demand balance were mixed. ROs top concerns reflect areas of attention for the healthcare sector as a whole.« less

Little information is currently available concerning young medical students desire to pursue a career in oncology, or their career expectations. This project is a cross-sectional epidemiological study. A voluntary and anonymous questionnaire was distributed to all young oncologists studying in France between the 2nd of October 2013 and the 23rd of February 2014. The overall response rate was 75.6%. A total of 505 young oncologists completed the questionnaire. The main determining factors in the decision to practice oncology were the cross-sectional nature of the field (70.8%), the depth and variety of human relations (56.3%) and the multi-disciplinary field of work (50.2%). Most residents would like to complete a rotation outside of their assigned region (59.2%) or abroad (70.2%) in order to acquire additional expertise (67.7%). In addition, most interns would like to undertake a fellowship involving care, teaching and research in order to hone their skills (85.7%) and forge a career in public hospitals (46.4%). Career prospects mainly involve salaried positions in public hospitals. Many young oncologists are concerned about their professional future, due to the shortage of openings (40.8%), the workload (52.8%) and the lack of work-life balance (33.4%). This investigation provides a comprehensive profile of the reasons young oncologists chose to pursue a career in oncology, and their career prospects.

Introducton: Treatment of hereditary renal cell carcinoma (HRCC) requires a multidisciplinary approach that may involve medical oncologists, geneticists, genetic counsellors, and urologists. The objective of our survey was to obtain current and representative information about the use and perceived importance of genetic testing for HRCC in Canada. Methods: A self-administered web-based survey was provided to Canadian medical oncologists, geneticists, genetic counsellors, and urologists in collaboration with their respective associations. The survey was created through an iterative process in consultation with the Kidney Cancer Research Network of Canada and contained both quantitative and qualitative components. The survey was designed to be exploratory and results were compared across regions. Results: The overall response was low (6.6%). Of the respondents, 42%, 33%, 19%, 5% were genetic counsellors, urologists, medical oncologists and medical geneticists, respectively. Of the respondents, 62.7% described their practice as academic, and 37.3% described it as non-academic. Non-academic respondents tended to refer for genetic counselling less frequently than academic (48.6% vs. 67.2%). Most respondents believed that genetic testing for HRCC was available (82.8%), although 47.7% did not know which tests were available. This observation was consistent across provinces. Testing for Von Hippel-Lindau syndrome was given the highest priority among respondents. Limited provider knowledge, clinical guidelines, institutional funding, access, and poor coordination between disciplines were cited as barriers to testing. Interpretation: There is a need to increase provider knowledge of genetic testing for HRCC. These findings support the development of practice guidelines and national strategies to improve coordination of specialists and access to genetics services. Limitations of the present study include low survey response which did not allow for inferential analysis by geographic region or respondent specialty. PMID:25485012

Purpose: Although complementary and alternative medicine (CAM) utilization in breast cancer patients is reported to be high, there are few data on CAM practices in breast patients specifically during radiation. This prospective, multi-institutional study was conducted to define CAM utilization in breast cancer during definitive radiation. Materials/Methods: A validated CAM instrument with a self-skin assessment was administered to 360 Stage 0-III breast cancer patients from 5 centers during the last week of radiation. All data were analyzed to detect significant differences between users/nonusers. Results: CAM usage was reported in 54% of the study cohort (n=194/360). Of CAM users, 71% reportedmore » activity-based CAM (eg, Reiki, meditation), 26% topical CAM, and 45% oral CAM. Only 16% received advice/counseling from naturopathic/homeopathic/medical professionals before initiating CAM. CAM use significantly correlated with higher education level (P<.001), inversely correlated with concomitant hormone/radiation therapy use (P=.010), with a trend toward greater use in younger patients (P=.066). On multivariate analysis, level of education (OR: 6.821, 95% CI: 2.307-20.168, P<.001) and hormones/radiation therapy (OR: 0.573, 95% CI: 0.347-0.949, P=.031) independently predicted for CAM use. Significantly lower skin toxicity scores were reported in CAM users vs nonusers, respectively (mild: 34% vs 25%, severe: 17% vs 29%, P=.017). Conclusion: This is the first prospective study to assess CAM practices in breast patients during radiation, with definition of these practices as the first step for future investigation of CAM/radiation interactions. These results should alert radiation oncologists that a large percentage of breast cancer patients use CAM during radiation without disclosure or consideration for potential interactions, and should encourage increased awareness, communication, and documentation of CAM practices in patients undergoing radiation treatment for breast cancer.« less

Burnout syndrome in the practice of oncology: results of a random survey of 1,000 oncologists.

Burnout, the end result of stress, can occur in any profession. We set out to determine the extent of burnout among a representative group of American oncologists. A questionnaire with 12 specific points was designed and prepared by the authors. It was mailed to 1,000 randomly selected physician subscribers to the Journal of Clinical Oncology. Five hundred ninety-eight completed surveys (60%) were returned before the cut-off date and included in the analysis. Overall, 56% of the respondents reported experiencing burnout in their professional life. No significance was found between the incidence of burnout and specialty within oncology, year medical training ended, or practice location. Significance was found, however, between type of practice and the incidence of burnout; institution- or university-based oncologists reported a lower incidence of burnout (47%) versus all other types of practice (66% burnout rate for oncology plus internal medicine, 63% for private adult oncology only, 39% for pediatric oncologists [there were too few pediatric oncologists for this rate to be significant], and 64% for others; P = .0003). Frustration or a sense of failure was the most frequently chosen (56%) description of burnout, and insufficient personal and/or vacation time was the most frequent reason (57%) chosen to explain the existence of burnout. To alleviate burnout, the majority (69%) of respondents indicated the need for more vacation or personal time. Administering palliative or terminal care, reimbursement issues, and a heavy work load were identified as contributing factors to burnout. Given the high response to the questionnaire and a 56% incidence of burnout in the surveyed population, it is concluded that further research on this issue is required.

Purpose To evaluate the career plans, professional expectations, and well-being of oncology fellows compared with actual experiences of practicing oncologists. Methods US oncology fellows taking the 2013 Medical Oncology In-Training Examination (MedOnc ITE) were invited to participate in an optional postexamination survey. The survey evaluated fellows' career plans and professional expectations and measured burnout, quality of life (QOL), fatigue, and satisfaction with work-life balance (WLB) using standardized instruments. Fellows' professional expectations and well-being were compared with actual experiences of US oncologists assessed simultaneously. Results Of the 1,637 oncology fellows in the United States, 1,373 (83.9%) took the 2013 MedOnc ITE. Among these, 1,345 (97.9%) completed the postexamination survey. The frequency of burnout among fellows decreased from 43.3% in year 1 to 31.7% in year 2 and 28.1% in year 3 (P < .001). Overall, the rate of burnout among fellows and practicing oncologists was similar (34.1% v 33.7%; P = .86). With respect to other dimensions of well-being, practicing oncologists had lower fatigue (P < .001) and better overall QOL scores (P < .001) than fellows but were less satisfied with WLB (P = .0031) and specialty choice (P < .001). Fellows' expectations regarding future work hours were 5 to 6 hours per week fewer than oncologists' actual reported work hours. Levels of burnout (P = .02) and educational debt (P ≤ .004) were inversely associated with ITE scores. Fellows with greater educational debt were more likely to pursue private practice and less likely to plan an academic career. Conclusion Oncology fellows entering practice trade one set of challenges for another. Unrealized expectations regarding work hours may contribute to future professional dissatisfaction, burnout, and challenges with WLB. PMID:25049326

If the Mountain Does Not Come to Mohammad: The Significance of Guest Operations for Early Stage Ovarian Cancer.

2014-10-01

Background: In women with early ovarian cancer (EOC), comprehensive surgical staging is known to enhance ovarian cancer outcomes and requires specific surgical competence. Given that centralization of care remains a topic of continuing debate, a system of "guest operations" was introduced in the midwestern part of The Netherlands. During a guest operation a gynecologic oncologist participates in oncology surgery performed in the community hospital. Objective: This study was conducted to examine the effects of the presence of a gynecologic oncologist on the quality of staging, treatment, and survival in patients with EOC. Materials and Methods: All patients with a pathologically confirmed diagnosis of EOC between January 2000 and December 2009 were selected from a regional cancer registry. Surgical accuracy was checked on the basis of each patient's file, operative notes, and pathology report. Results: A total of 130 patients were included, of whom 15 were treated in the Leiden University Medical Center (LUMC) and 115 in eight regional community hospitals. If a gynecologic oncologist attended the operation, surgical staging was more often adequately performed, 81.1% versus 32.1% when a gynecologic oncologist was not present ( p <0.001). Adherence to protocol was observed in 76.9% of operations when a gynecologic oncologist had been present, compared to 49.5% of patients who were treated by a general gynecologist alone ( p =0.004). The 5-year disease-free survival was borderline significantly in favor of optimally staged patients, 75.1% in those who were not staged optimally versus 90.9% who were staged optimally ( p =0.058). Conclusions: Guest operations deserve a distinguished place among the treatment modalities available to patients with EOC, because surgery by the most specialized and experienced surgeons contributes to better care.

Thromboembolic complications represent one of the most important cause of morbidity and mortality in cancer patients. Although several data have been published demonstrating the strong association between cancer and venous thromboembolism (VTE), there is poor perception, among oncologists, of the level of risk of thrombosis and of relevance of managing VTE in these patients. The Associazione Italiana di Oncologia Medica (AIOM) has provided some recommendations to direct clinical practice according to evidence-based data concerning cancer and VTE. In fact, we conducted an extensive literature review (1996-2005) to produce evidence-based recommendations to improve perceptions of the magnitude of this risk among Italian medical and surgical oncologists and alert on the new approaches to prophylaxis and treatment of VTE in cancer patients. Levels of evidence are given according to a five-point rating system, and similarly for each key recommendation a five-point rating system suggests if the evidence is strong and indicate that the benefits do, or do not, outweigh risks and burden.

While a lot is known about potential and actual turnover of non-medical hospital staff, only few data exist for the outpatient setting. In addition, little is known about actual instruments which leaders can use to influence staff turnover in physician practices. In the literature, the social capital of an organisation, which means the amount of trust, common values and reciprocal behaviour in the organisation, has been discussed as a possible field of action. In the present study, staff turnover as perceived by outpatient haematologists and oncologists is presented and analysed as to whether social capital is associated with that staff turnover. In conclusion, measures to increase the social capital of a practice are presented. The present study is based on data gathered in a questionnaire-based survey with members of the Professional Organisation of -Office-Based Haematologists and Oncologists (N=551). The social capital of the practice was captured from the haematologists and oncologists using an existing and validated scale. To analyse the impact of the practice's social capital on staff turnover, as perceived by the physicians, bivariate correlations and linear regression analyses were calculated. In total, 152 haematologists and oncologists participated in the study which represents a response rate of 28%. In the regression analyses, social capital appears as a significant and strong predictor of staff turnover (beta=-0.34; p<0.001). Building social capital within the practice may be an important contribution to reducing staff turnover although the underlying study design does not allow for drawing causal conclusions regarding this relationship. To create social capital in their practice, outpatient physicians may apply measures that facilitate social interaction among staff, foster trust and facilitate cooperation. Such measures may already be applied when hiring and training new staff, but also continuously when leading employees and when organising work tasks, e.g., by establishing regular team meetings. © Georg Thieme Verlag KG Stuttgart · New York.

The role of tumor board conferences in neuro-oncology: a nationwide provider survey.

The tumor board or multidisciplinary cancer meeting (MCM) is the foundation of high value multidisciplinary oncology care, coordinating teams of specialists. Little is known on how these meetings are implemented in Neuro-oncology. Benefits of MCMs include coordination, direction for complicated cases, education, and a forum for communication, emerging technology, and clinical trials. This study identifies participation and utilization of neuro-oncology MCMs. A cross-sectional descriptive survey was dispersed through an internet questionnaire. The Society of Neuro-Oncology and the American Brain Tumor Association provided a list of dedicated neuro-oncology centers. All National Cancer Institute designated centers, and participants in the Adult Brain Tumor Consortium or the Brain Tumor Trials Collaborative were included, identifying 85 centers. Discussion included primary brain tumors (100%), challenging cases (98%), recurrent disease (96%), neoplastic spine disease (93%), metastatic brain lesions (89%), pre-surgical cases (82%), pathology (76%), and paraneoplastic disease (40%). MCMs were composed of neuro-oncologists, neurosurgeons, and radiation oncologists (100%), radiologists (98%), pathologists (96%), and clinical trial participants (64%). Individual preparation ranged from 15 to 300 min. MCMs were valued for clinical decision making (94%), education (89%), and access to clinical trials (69%). 13% documented MCMs in the medical record. 38% of centers used a molecular tumor board; however, many commented with uncertainty as to how this is defined. Neuro-oncology MCMs at leading U.S. institutions demonstrate congruity of core disciplines, cases discussed, and perceived value. We identified variability in preparation time and implementation of MCM recommendations. There is high uncertainty as to the definition and application of a molecular tumor board.

Background Currently, the specific role of family physicians (fps) in the care of people with cancer is not well defined. Our goal was to explore physician perspectives and contextual factors related to the coordination of cancer care and the role of fps. Methods Using a constructivist grounded theory approach, we conducted telephone interviews with 58 primary and cancer specialist health care providers from across Canada. Results The participants—21 fps, 15 surgeons, 12 medical oncologists, 6 radiation oncologists, and 4 general practitioners in oncology—were asked to describe both the role that fps currently play and the role that, in their opinion, fps should play in the future care of cancer patients across the cancer continuum. Participants identified 3 key roles: coordinating cancer care, managing comorbidities, and providing psychosocial care to patients and their families. However, fps and specialists discussed many challenges that prevent fps from fully performing those roles: ■ The fps described communication problems resulting from not being kept “in the loop” because they weren’t copied on patient reports and also the lack of clearly defined roles for all the various health care providers involved in providing care to cancer patients.■ The specialists expressed concerns about a lack of patient access to fp care, leaving specialists to fill the care gaps. The fps and specialists both recommended additional training and education for fps in survivorship care, cancer screening, genetic testing, and new cancer treatments. Conclusions Better communication, more collaboration, and further education are needed to enhance the role of fps in the care of cancer patients. PMID:28490920

We analysed the radiotherapy planning process at the London Regional Cancer Program to determine the bottlenecks and to quantify the effect of specific resource levels with the goal of reducing waiting times. We developed a discrete-event simulation model of a patient's journey from the point of referral to a radiation oncologist to the start of radiotherapy, considering the sequential steps and resources of the treatment planning process. We measured the effect of several resource changes on the ready-to-treat to treatment (RTTT) waiting time and on the percentage treated within a 14 calendar day target. Increasing the number of dosimetrists by one reduced the mean RTTT by 6.55%, leading to 84.92% of patients being treated within the 14 calendar day target. Adding one more oncologist decreased the mean RTTT from 10.83 to 10.55 days, whereas a 15% increase in arriving patients increased the waiting time by 22.53%. The model was relatively robust to the changes in quantity of other resources. Our model identified sensitive and non-sensitive system parameters. A similar approach could be applied by other cancer programmes, using their respective data and individualised adjustments, which may be beneficial in making the most effective use of limited resources.

To assess the clinical relevance of a semiautomatic CT-based ensemble segmentation method, by comparing it to pathology and to CT/PET manual delineations by five independent radiation oncologists in non-small cell lung cancer (NSCLC). For 20 NSCLC patients (stages Ib-IIIb) the primary tumor was delineated manually on CT/PET scans by five independent radiation oncologists and segmented using a CT based semi-automatic tool. Tumor volume and overlap fractions between manual and semiautomatic-segmented volumes were compared. All measurements were correlated with the maximal diameter on macroscopic examination of the surgical specimen. Imaging data are available on www.cancerdata.org. High overlap fractions were observed between the semi-automatically segmented volumes and the intersection (92.5±9.0, mean±SD) and union (94.2±6.8) of the manual delineations. No statistically significant differences in tumor volume were observed between the semiautomatic segmentation (71.4±83.2 cm(3), mean±SD) and manual delineations (81.9±94.1 cm(3); p=0.57). The maximal tumor diameter of the semiautomatic-segmented tumor correlated strongly with the macroscopic diameter of the primary tumor (r=0.96). Semiautomatic segmentation of the primary tumor on CT demonstrated high agreement with CT/PET manual delineations and strongly correlated with the macroscopic diameter considered as the "gold standard". This method may be used routinely in clinical practice and could be employed as a starting point for treatment planning, target definition in multi-center clinical trials or for high throughput data mining research. This method is particularly suitable for peripherally located tumors. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

2017-11-28

In Europe, treatment of metastatic colorectal cancer (mCRC) with panitumumab requires prior confirmation of RAS wild-type mutation status. Two studies - a physician survey and a medical records review (MRR) - were conducted to evaluate the use of panitumumab and awareness among prescribing oncologists of the associated RAS testing requirements in clinical practice. Both studies enrolled participants from nine European countries and were carried out in three consecutive rounds. Rounds 1 and 2 (2012-2013) examined KRAS (exon 2) testing only; the results have been published in full previously. Round 3 (2014-2015) examined full RAS testing (exons 2, 3, 4 of KRAS and NRAS) and was initiated following a change in prescribing guidelines, from requiring KRAS alone to requiring full RAS testing. For the physician survey, telephone interviews were conducted with oncologists who had prescribed panitumumab to patients with mCRC in the previous 6 months. For the MRR, oncologists were asked to provide anonymised clinical information, extracted from their patients' records. In Round 3, 152 oncologists and 131 patients' records were included in the physician survey and MRR, respectively. In Round 3 of the physician survey, 95.4% (n = 145) of participants correctly identified that panitumumab should only be prescribed in RAS wild-type mCRC compared with 99.0% (n = 298) of 301 participants in Rounds 1 and 2, responding to the same question about KRAS testing. In Round 3 of the MRR, 100% (n = 131) of patients included in the study had confirmed KRAS or RAS wild-type status prior to initiation of panitumumab compared with 97.7% (n = 299) of 306 patients in Rounds 1 and 2 (KRAS only). Of those patients in Round 3, 83.2% (n = 109) had been tested for RAS status and 16.8% (n = 22) had been tested for KRAS status only. Physicians' adherence to prescribing guidelines has remained high over time in Europe, despite the change in indication for panitumumab treatment, from KRAS to RAS wild-type mCRC. Additionally, this study demonstrates the uptake of full RAS testing among the majority of oncologists and pathologists.

Radiation retinopathy: case report and review.

2007-04-05

Ocular damage from radiation treatment is a well established phenomenon. Many factors are now known to influence the incidence of radiation retinopathy, including total dosage and daily fraction size. Patients who are diabetic, hypertensive or received previous chemotherapy are more susceptible to radiation retinopathy. A 55 year old male was referred from the oncology department with epiphora. His medical history included Type 2 Insulin treated Diabetes Mellitus and hypertension. One year prior to presentation he had undergone a total rhinectomy with a 4 week course of post-operative radiotherapy for an aggressive sqaumous cell carcinoma of the nose. On examination the visual acuity was noted to be 6/36 left eye and 6/9 right eye. Posterior segment examination revealed marked retinal ischaemia present in the posterior pole and macular region of both eyes. The appearance was not thought to be typical of diabetic changes, radiation retinopathy being the more likely diagnosis especially in view of his history. Over the next four months the vision in both eyes rapidly deteriorated to 3/60 left eye and 1/60 right eye. Bilateral pan retinal photocoagulation was thought to be appropriate treatment at this point. This case highlights the importance for ophthalmologists and oncologists to be aware of the close relationship between diabetes and radiation treatment and the profound rapid impact this combination of factors may have on visual function. Radiation is being used with increasing frequency for ocular and orbital disease, because of this more cases of radiation retinopathy may become prevalent. Factors which may potentiate radiation retinopathy should be well known including, increased radiation dosage, increased fraction size, concomitant systemic vascular disease and use of chemotherapy. Counselling should be offered in all cases at risk of visual loss. As no effective treatment currently exists to restore visual function, monitoring of visual acuity in all cases and early referral to the ophthalmologist as appropriate is warranted.

Purpose: This study examines the role of {sup 18}F-labeled fluorodeoxyglucose positron emission tomography (FDG-PET) in the implementation of involved-node radiation therapy (INRT) in patients treated for clinical stages (CS) I/II supradiaphragmatic Hodgkin lymphoma (HL). Methods and Material: Patients with untreated CS I/II HL enrolled in the randomized EORTC/LYSA/FIL Intergroup H10 trial and participating in a real-time prospective quality assurance program were prospectively included in this study. Data were electronically obtained from 18 French cancer centers. All patients underwent APET-computed tomography (PET-CT) and a post-chemotherapy planning CT scanning. The pre-chemotherapy gross tumor volume (GTV) and the postchemotherapy clinical target volume (CTV) weremore » first delineated on CT only by the radiation oncologist. The planning PET was then co-registered, and the delineated volumes were jointly analyzed by the radiation oncologist and the nuclear medicine physician. Lymph nodes undetected on CT but FDG-avid were recorded, and the previously determined GTV and CTV were modified according to FDG-PET results. Results: From March 2007 to February 2010, 135 patients were included in the study. PET-CT identified at least 1 additional FDG-avid lymph node in 95 of 135 patients (70.4%; 95% confidence interval [CI]: 61.9%-77.9%) and 1 additional lymph node area in 55 of 135 patients (40.7%; 95% CI: 32.4%-49.5%). The mean increases in the GTV and CTV were 8.8% and 7.1%, respectively. The systematic addition of PET to CT led to a CTV increase in 60% of the patients. Conclusions: Pre-chemotherapy FDG-PET leads to significantly better INRT delineation without necessarily increasing radiation volumes.« less

Purpose: To recognize the current status of stereotactic body radiotherapy (SBRT) in Japan, using a nationwide survey conducted by the Japan 3-D Conformal External Beam Radiotherapy Group. Methods and Materials: The questionnaire was sent by mail to 117 institutions. Ninety-four institutions (80%) responded by the end of November 2005. Fifty-three institutions indicated that they have already started SBRT, and 38 institutions had been reimbursed by insurance. Results: A total of 1111 patients with histologically confirmed lung cancer were treated. Among these patients, 637 had T1N0M0 and 272 had T2N0M0 lung cancer. Metastatic lung cancer was found in 702 and histologicallymore » unconfirmed lung tumor in 291 patients. Primary liver cancer was found in 207 and metastatic liver cancer in 76 patients. The most frequent schedule used for primary lung cancer was 48Gy in 4 fractions at 22 institutions (52%), followed by 50Gy in 5 fractions at 11 institutions (26%) and 60Gy in 8 fractions at 4 institutions (10%). The tendency was the same for metastatic lung cancer. The average number of personnel involved in SBRT was 1.8 radiation oncologists, including 1.1 certified radiation oncologists, 2.8 technologists, 0.7 nurses, and 0.6 certified quality assurance personnel and 0.3 physicists. The most frequent amount of time for treatment planning was 61-120min, for quality assurance was 50-60min, and for treatment was 30min. There were 14 (0.6% of all cases) reported Grade 5 complications: 11 cases of radiation pneumonitis, 2 cases of hemoptysis, and 1 case of radiation esophagitis. Conclusion: The current status of SBRT in Japan was surveyed.« less

2008-08-01

Purpose: The German Hodgkin Study Group (GHSG) set up a radiotherapy (RT) reference center within the Department of Radiation Oncology at University of Cologne to undertake quality assurance of the group's clinical studies. In the HD10 trial (early-favorable stages) and HD11 trial (early-unfavorable stages) all patients received involved field (IF)-RT (30 Gy vs. 20 Gy) within a combined-modality approach. For these patients a central prospective review of all diagnostic imaging was performed by expert radiation oncologists to control disease extension and to define IF treatment volume. Methods and Materials: On the basis of simulation films, verification films, and radiotherapy casemore » report form (CRF) an expert panel evaluated retrospectively the adequacy of irradiated IF treatment portals according to the RT prescription, applied radiation doses, treatment time, and technical parameters. Results: Between 1999 and 2006 a total of 825 of 1370 randomized patients of the HD10 trial (60%) and 954 of 1422 patients of the HD11 trial (67%) were evaluated by the panel. Radiotherapy was rated as suboptimal in 47% of all reviewed cases. Although the participating RT centers received a precise RT prescription, most difficulties occurred in the adequate coverage of the IF (40%), followed by technical faults (12%). Deviations from the prescribed single daily dose (1.8-2 Gy), weekly dose, and total reference dose were rare (1%). Conclusions: As a consequence of these findings, radiation oncologists were trained on the definition of IF-RT at GHSG meetings and at the annual meetings of the German Society for Therapeutic Radiation Oncology. Possible correlations between RT quality and relapse rate will be investigated.« less

Second medical opinions: the views of oncology patients and their physicians.

2010-09-01

Second medical opinions (SMOs) are common in oncology practice, but the nature of these consultations has received relatively little attention. This study examines the views of patients with advanced cancer and their physicians of SMOs. Parallel, concurrent surveys were developed for patients and physicians. The first was distributed to outpatients with advanced cancer-attending specialist clinics in an Australian quaternary hospital. The second survey, developed on the basis of results of exploratory interviews with medical oncologists, was distributed to medical oncologists in Australia. Seventeen of fifty two (33%) patients had sought a SMO, most commonly prompted by concerns around communication with their first doctor, the extreme and desperate nature of their medical condition and the need for reassurance. Most (94%) patients found the SMO helpful, with satisfaction related to improved communication and reassurance. Patients were concerned that seeking a second medical opinion may affect their relationship with their primary doctor. Most physicians (82%) reported seeing between one and five SMO per month, with patients being motivated by the need for additional information and reassurance. Physicians regarded SMO patients as having greater information needs (84%), greater psychosocial needs (58%) and requiring more of the physician's time and energy (77%) than other patients. SMOs are common in cancer care with most patients motivated by the need for improved communication, additional information and reassurance. Physicians identify patients who seek SMOs as having additional psychosocial needs compared with other oncology patients.

To monitor and address disparity in accrual, patient participation in cancer clinical trials is routinely summarized by race/ethnicity. To investigate whether confounding obscures racial/ethnic disparity in participation, all women with breast cancer treated by medical oncologists at City of Hope Comprehensive Cancer Center from 2004 through 2009 were classified by birthplace and self-reported race/ethnicity, and followed for accrual onto therapeutic trials through 2010. Undetectable on univariate analysis, significantly reduced participation by subjects of African, Asian, Eastern European, Latin American, and Middle Eastern ancestries was revealed after accounting for age, socioeconomic factors, tumor and oncologist characteristics, and intrapractice clustering of patients.

The purpose of this study was to evaluate the present status of radiotherapy infrastructure and human resources in Switzerland and compute projections for 2020. The European Society of Therapeutic Radiation Oncology "Quantification of Radiation Therapy Infrastructure and Staffing" guidelines (ESTRO-QUARTS) and those of the International Atomic Energy Agency (IAEA) were applied to estimate the requirements for teleradiotherapy (TRT) units, radiation oncologists (RO), medical physicists (MP) and radiotherapy technologists (RTT). The databases used for computation of the present gap and additional requirements are (a) Global Cancer Incidence, Mortality and Prevalence (GLOBOCAN) for cancer incidence (b) the Directory of Radiotherapy Centres (DIRAC) of the IAEA for existing TRT units (c) human resources from the recent ESTRO "Health Economics in Radiation Oncology" (HERO) survey and (d) radiotherapy utilization (RTU) rates for each tumour site, published by the Ingham Institute for Applied Medical Research (IIAMR). In 2015, 30,999 of 45,903 cancer patients would have required radiotherapy. By 2020, this will have increased to 34,041 of 50,427 cancer patients. Switzerland presently has an adequate number of TRTs, but a deficit of 57 ROs, 14 MPs and 36 RTTs. By 2020, an additional 7 TRTs, 72 ROs, 22 MPs and 66 RTTs will be required. In addition, a realistic dynamic model for calculation of staff requirements due to anticipated changes in future radiotherapy practices has been proposed. This model could be tailor-made and individualized for any radiotherapy centre. A 9.8 % increase in radiotherapy requirements is expected for cancer patients over the next 5 years. The present study should assist the stakeholders and health planners in designing an appropriate strategy for meeting future radiotherapy needs for Switzerland.

To analyze the impact of mobile electronic devices (MEDs) and apps in the daily clinical activity of young radiation or clinical oncologists in 5 Western European countries (Italy, Germany, Spain, Portugal, and Denmark). A web-based questionnaire was sent to 462 young (≤40 years) members of the national radiation or clinical oncology associations of the countries involved in the study. The 15 items investigated diffusion of MEDs (smartphones and/or tablets), their impact on daily clinical activity, and the differences perceived by participants along time. A total of 386 (83.5%) of the 462 correctly filled questionnaires were statistically evaluated. Up to 65% of respondents declared to use an electronic device during their clinical activity. Conversely, 72% considered low to moderate impact of smartphones/tables on their daily practice. The daily use significantly increased from 2009 to 2012: users reporting a use ≥6 times/d raised from 5% to 39.9%. Professional needs fulfillment was declared by less than 68% of respondents and compliance to apps indications by 66%. Significant differences were seen among the countries, in particular concerning the feeling of usefulness of MEDs in the daily clinical life. The perception of the need of a comprehensive Web site containing a variety of applications (apps) for clinical use significantly differed among countries in 2009, while it was comparable in 2012. This survey showed a large diffusion of MEDs in young professionals working in radiation oncology. Looking at these data, it is important to verify the consistency of information found within apps, in order to avoid potential errors eventually detrimental for patients. "Quality assurance" criteria should be specifically developed for medical apps and a comprehensive Web site gathering all reliable applications and tools might be useful for daily clinical practice. © The Author(s) 2015.

How Radiation Oncologists Evaluate and Incorporate Life Expectancy Estimates Into the Treatment of Palliative Cancer Patients: A Survey-Based Study

DOE Office of Scientific and Technical Information (OSTI.GOV)

Tseng, Yolanda D., E-mail: ydtseng@partners.org; Krishnan, Monica S.; Sullivan, Adam J.

2013-11-01

Purpose: We surveyed how radiation oncologists think about and incorporate a palliative cancer patient’s life expectancy (LE) into their treatment recommendations. Methods and Materials: A 41-item survey was e-mailed to 113 radiation oncology attending physicians and residents at radiation oncology centers within the Boston area. Physicians estimated how frequently they assessed the LE of their palliative cancer patients and rated the importance of 18 factors in formulating LE estimates. For 3 common palliative case scenarios, physicians estimated LE and reported whether they had an LE threshold below which they would modify their treatment recommendation. LE estimates were considered accurate whenmore » within the 95% confidence interval of median survival estimates from an established prognostic model. Results: Among 92 respondents (81%), the majority were male (62%), from an academic practice (75%), and an attending physician (70%). Physicians reported assessing LE in 91% of their evaluations and most frequently rated performance status (92%), overall metastatic burden (90%), presence of central nervous system metastases (75%), and primary cancer site (73%) as “very important” in assessing LE. Across the 3 cases, most (88%-97%) had LE thresholds that would alter treatment recommendations. Overall, physicians’ LE estimates were 22% accurate with 67% over the range predicted by the prognostic model. Conclusions: Physicians often incorporate LE estimates into palliative cancer care and identify important prognostic factors. Most have LE thresholds that guide their treatment recommendations. However, physicians overestimated patient survival times in most cases. Future studies focused on improving LE assessment are needed.« less

This study aimed to analyze gender differences in rank, career duration, publication productivity, and research funding among radiation oncologists at U.S. academic institutions. For 82 domestic academic radiation oncology departments, the authors identified current faculty and recorded their academic rank, degree, and gender. The authors recorded bibliographic metrics for physician faculty from a commercially available database (Scopus, Elsevier BV), including numbers of publications from 1996 to 2012 and h-indices. The authors then concatenated these data with National Institutes of Health (NIH) funding per Research Portfolio Online Reporting Tools. The authors performed descriptive and correlative analyses, stratifying by gender and rank. Of 1,031 faculty, 293 (28%) women and 738 (72%) men, men had a higher median m-index, 0.58 (range 0-3.23) versus 0.47 (0-2.5) (P < .05); h-index, 8 (0-59) versus 5 (0-39) (P < .05); and publication number, 26 (0-591) versus 13 (0-306) (P < .05). Men were more likely to be senior faculty and receive NIH funding. After stratifying for rank, these differences were largely nonsignificant. On multivariate analysis, there were correlations between gender, career duration and academic position, and h-index (P < .01). Determinants of a successful career in academic medicine are multifactorial. Data from radiation oncologists show a systematic gender association, with fewer women achieving senior faculty rank. However, women achieving seniority have productivity metrics comparable to those of male counterparts. This suggests that early career development and mentorship of female faculty may narrow productivity disparities.

The purpose of this study was for us to present our findings on the prospectively audited impact of head and neck multidisciplinary team meetings on patient management. We collected clinical data, the pre-multidisciplinary team meeting treatment plan, the post-multidisciplinary team meeting treatment plans, and follow-up data from all patients discussed at a weekly multidisciplinary team meeting and we recorded the changes in management. One hundred seventy-two patients were discussed in 39 meetings. In 52 patients (30%), changes in management were documented of which 20 (67%) were major. Changes were statistically more likely when the referring physician was a medical or radiation oncologist, when the initial treatment plan did not include surgery, and when the histology was neither mucosal squamous cell cancer nor a skin malignancy. Compliance to the multidisciplinary team meeting treatment recommendation was 84% for all patients and 70% for patients with changes in their treatment recommendation. Head and neck multidisciplinary team meetings changed management in almost a third of the cases. © 2014 Wiley Periodicals, Inc.

As a result of recent progress in detection techniques, circulating tumor DNA (ctDNA) and circulating tumor cells (CTC) can now be accurately detected in the blood of most cancer patients. While these new biomarkers can provide a better understanding of key biological mechanisms underlying cancer growth and dissemination, they also open up a wide range of possible clinical applications in medical oncology, radiation oncology and surgical oncology. In this review, we summarize the results obtained with ctDNA and CTC together with their potential future clinical applications in the field of surgical oncology, with particular focus on the perioperative setting of various types of cancer. These applications include, but are not limited to, cancer screening, early diagnosis, prognostic assessment, evaluation and management of preoperative systemic or local therapies, post-surgical detection of minimal residual disease and early detection of cancer relapse.

SU-E-E-03: Shared Space Fosters Didactic and Professional Learning Across Professions for Medical and Physics Residents

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dieterich, S; Perks, J; Fragoso, R

Purpose: Medical Physicists and Radiation Oncologists are two professions who should be working as a team for optimal patient care, yet lack of mutual understanding about each others respective role and work environment creates barriers To improve collaboration and learning, we designed a shared didactic and work space for physics and radiation oncology residents to maximize interaction throughout their professional training. Methods: Physician and Physics residents are required to take the same didactic classes, including journal clubs and respective seminars. The residents also share an office environment among the seven physician and two physic residents. Results: By maximizing didactic overlapmore » and sharing office space, the two resident groups have developed a close professional relationship and supportive work environment. Several joint research projects have been initiated by the residents. Awareness of physics tasks in the clinic has led to a request by the physician residents to change physics didactics, converting the physics short course into a lab-oriented course for the medical residents which is in part taught by the physics residents. The physics seminar is given by both residency groups; increased motivation and interest in learning about physics has led to several medical resident-initiated topic selections which generated lively discussion. The physics long course has changed toward including more discussion among residents to delve deeper into topics and study beyond what passing the boards would require. A supportive work environment has developed, embedding the two physics residents into a larger residents group, allowing them to find mentor and peers more easily. Conclusion: By creating a shared work and didactic environment, physician and physics residents have improved their understanding of respective professional practice. Resident-initiated changes in didactic practice have led to improved learning and joint research. A strong social support system has developed, embedding physics residents into a larger peer group.« less

Increasing numbers of patients receive active ambulatory oncology treatment over prolonged periods of time. Many of these patients suffer from additional comorbidities and require comprehensive medical care. We aimed to assess the perception of patients with cancer regarding the role of the family physician and the oncologist in their care during times of active cancer treatment. A survey was conducted among 265 consecutive chemotherapy-treated patients at the daycare oncology clinic. All the patients were affiliated with one of four Israeli health maintenance organizations, 96% had a regular family physician, and 70% had met with him during the preceding month. Only one third of the patients thought their family physician was trained to or was willing to treat medical problems that occurred during chemotherapy treatment. Yet most patients, irrespective of clinical or socioeconomic variables, stated that involvement of the family physician was important to them. Only 30% stated that the oncologist communicated with the family physician. Accordingly, 72% of the patients stated that in the case of an urgent problem they would turn first to the oncology clinic; only 9% would consult their family physician. Our data point to a lack of communication between team members and inadequate medical training as major barriers for comprehensive medical care for chemotherapy-treated patients with cancer. Communication between treating teams may improve medical care for oncology patients with multiple treating practitioners. Copyright © 2014 by American Society of Clinical Oncology.

Interactive contour delineation of organs at risk in radiotherapy: Clinical evaluation on NSCLC patients.

Accurate delineation of organs at risk (OARs) on computed tomography (CT) image is required for radiation treatment planning (RTP). Manual delineation of OARs being time consuming and prone to high interobserver variability, many (semi-) automatic methods have been proposed. However, most of them are specific to a particular OAR. Here, an interactive computer-assisted system able to segment various OARs required for thoracic radiation therapy is introduced. Segmentation information (foreground and background seeds) is interactively added by the user in any of the three main orthogonal views of the CT volume and is subsequently propagated within the whole volume. The proposed method is based on the combination of watershed transformation and graph-cuts algorithm, which is used as a powerful optimization technique to minimize the energy function. The OARs considered for thoracic radiation therapy are the lungs, spinal cord, trachea, proximal bronchus tree, heart, and esophagus. The method was evaluated on multivendor CT datasets of 30 patients. Two radiation oncologists participated in the study and manual delineations from the original RTP were used as ground truth for evaluation. Delineation of the OARs obtained with the minimally interactive approach was approved to be usable for RTP in nearly 90% of the cases, excluding the esophagus, which segmentation was mostly rejected, thus leading to a gain of time ranging from 50% to 80% in RTP. Considering exclusively accepted cases, overall OARs, a Dice similarity coefficient higher than 0.7 and a Hausdorff distance below 10 mm with respect to the ground truth were achieved. In addition, the interobserver analysis did not highlight any statistically significant difference, at the exception of the segmentation of the heart, in terms of Hausdorff distance and volume difference. An interactive, accurate, fast, and easy-to-use computer-assisted system able to segment various OARs required for thoracic radiation therapy has been presented and clinically evaluated. The introduction of the proposed system in clinical routine may offer valuable new option to radiation oncologists in performing RTP.

The Union for International Cancer Control (UICC) is a membership-based, non-governmental organization with a mandate to “…to unite the cancer community to reduce the global cancer burden, to promote greater equity, and to integrate cancer control into the world health and development agenda.” COMP is an associate member of the UICC. It is well recognized by the UICC that there are major gaps between high, and low and middle income countries, in terms of access to cancer services including access to radiation therapy. In this context, the UICC has developed a Global Task Force on Radiotherapy for Cancer Control withmore » a charge to answer a single question: “What does it cost to close the gap between what exists today and reasonable access to radiotherapy globally?” The Task Force consists of leaders internationally recognized for their radiation treatment related expertise (radiation oncologists, medical physicists, radiation therapists) as well as those with global health and economics specialization. The Task Force has developed three working groups: (1) to look at the global burden of cancer; (2) to look at the infrastructure requirements (facilities, equipment, personnel); and (3) to consider outcomes in terms of numbers of lives saved and palliated patients. A report is due at the World Cancer Congress in December 2014. This presentation reviews the infrastructure considerations under analysis by the second work group. The infrastructure parameters being addressed include capital costs of buildings and equipment and operating costs, which include human resources, equipment servicing and quality control, and general overhead.« less

SPIDERplan: A tool to support decision-making in radiation therapy treatment plan assessment.

PubMed

Ventura, Tiago; Lopes, Maria do Carmo; Ferreira, Brigida Costa; Khouri, Leila

2016-01-01

In this work, a graphical method for radiotherapy treatment plan assessment and comparison, named SPIDERplan, is proposed. It aims to support plan approval allowing independent and consistent comparisons of different treatment techniques, algorithms or treatment planning systems. Optimized plans from modern radiotherapy are not easy to evaluate and compare because of their inherent multicriterial nature. The clinical decision on the best treatment plan is mostly based on subjective options. SPIDERplan combines a graphical analysis with a scoring index. Customized radar plots based on the categorization of structures into groups and on the determination of individual structures scores are generated. To each group and structure, an angular amplitude is assigned expressing the clinical importance defined by the radiation oncologist. Completing the graphical evaluation, a global plan score, based on the structures score and their clinical weights, is determined. After a necessary clinical validation of the group weights, SPIDERplan efficacy, to compare and rank different plans, was tested through a planning exercise where plans had been generated for a nasal cavity case using different treatment planning systems. SPIDERplan method was applied to the dose metrics achieved by the nasal cavity test plans. The generated diagrams and scores successfully ranked the plans according to the prescribed dose objectives and constraints and the radiation oncologist priorities, after a necessary clinical validation process. SPIDERplan enables a fast and consistent evaluation of plan quality considering all targets and organs at risk.

An increasing number of surveys have investigated professional stress and satisfaction among oncologists. Coevally, structural development has changed the oncological working environment. This survey investigated the quality of life and job stress among German oncological physicians. A 48-item questionnaire, which included the 'Stress questionnaire of physicians and nurses' (FBAS), was developed by the 'Quality of life' working group of the Internal oncology study group (AIO), and distributed anonymously at the annual meeting of the AIO working group in 2010. Descriptive statistics as well as univariate and multivariate analysis were performed. 261 oncologists, mostly male (64%), older than 40 years (38%), and medical specialists (78%), took part in the survey. 'Structural conditions' were identified as causing the highest mean stress levels, followed by 'professional and private life'. Female participants showed a significantly lower global quality of life than male participants (p = 0.020). 'Structural conditions' induced more stress among younger oncologists < 50 years old (p < 0.001). Qualification status was influenced by gender (p < 0.001); the multivariate analysis described the dependence of gender (p = 0.0045), working situation (p = 0.0317) and global stress (p = 0.0008). Structural conditions, age younger than 50 years and female gender were identified as stress risk factors among the AIO members, and showed that job stress is present in German oncology. Further research is warranted to develop evidence-based intervention strategies. © 2015 S. Karger GmbH, Freiburg.

The first and only palliative care (PC) unit in Qatar was established in 2008 to serve adult patients with cancer. As PC was only recently introduced to oncology practice in Qatar and the region, raising awareness among physicians is crucial. This survey study is designed to outline the level of awareness and knowledge of oncologists in Qatar toward PC. In this cross-sectional survey study, copies of a self-constructed questionnaire were distributed to 49 physicians at the National Center for Cancer Care and Research in Qatar during January 2012 and collected for data analysis. The physician response rate was 100%. Less than half of the responders (36.7%) had official training in PC, but the majority (89.8%) showed interest in the field. Only 57.8% of the physicians reported self-competence in providing good PC to the dying patient. On the other hand, up to 69.4% are aware of the guidelines for pain relief and 58.7% apply them in their clinical practice. The concept of PC hospice was familiar to 77.1% of participants. On one hand, 85.7% of the physicians advocated that every medical center should have PC service, while up to 70.8% preferred that patients with short survival expectancy die in the community, rather than in a hospital setting. There is relatively good awareness and knowledge among health care providers specialized in cancer treatment in our hospital, despite the lack of formal training. Further training and informative sessions are required to raise awareness among oncologists and encourage utilization of PC services and thus optimize patient accessibility to PC.

Despite recently implemented access to care programs, Mexican breast cancer (BC) mortality rates remain substantially above those in the US. We conducted a survey among Mexican Oncologists to determine whether practice patterns may be responsible for these differences. A web-based survey was sent to 851 oncologists across Mexico using the Vanderbilt University REDCap database. Analyses of outcomes are reported using exact and binomial confidence bounds and tests. 138 participants (18.6% of those surveyed) from the National capital and 26 Mexican states, responded. Respondents reported that 58% of newly diagnosed BC patients present with stage III-IV disease; 63% undergo mastectomy, 52% axillary lymph node dissection (ALND) and 48% sentinel lymph node biopsy (SLNB). Chemotherapy is recommended for tumors > 1 cm (89%), positive nodes (86.5%), triple-negative (TN) (80%) and HER2 positive tumors (58%). Trastuzumab is prescribed in 54.3% and 77.5% for HER2 < 1 cm and > 1 cm tumors, respectively. Tamoxifen is indicated for premenopausal hormone receptor (HR) positive tumors in 86.5% of cases and aromatase inhibitors (AI's) for postmenopausal in 86%. 24% of physicians reported treatment limitations, due to delayed or incomplete pathology reports and delayed or limited access to medications. Even though access to care programs have been recently applied nationwide, women commonly present with advanced BC, leading to increased rates of mastectomy and ALND. Mexican physicians are dissatisfied with access to appropriate medical care. Our survey detects specific barriers that may impact BC outcomes in Mexico and warrant further investigation.

Cranial stereotactic radiosurgery: current status of the initial paradigm shifter.

Sheehan, Jason P; Yen, Chun-Po; Lee, Cheng-Chia; Loeffler, Jay S

2014-09-10

The concept of stereotactic radiosurgery (SRS) was first described by Lars Leksell in 1951. It was proposed as a noninvasive alternative to open neurosurgical approaches to manage a variety of conditions. In the following decades, SRS emerged as a unique discipline involving a collegial partnership among neurosurgeons, radiation oncologists, and medical physicists. SRS relies on the precisely guided delivery of high-dose ionizing radiation to an intracranial target. The focused convergence of multiple beams yields a potent therapeutic effect on the target and a steep dose fall-off to surrounding structures, thereby minimizing the risk of collateral damage. SRS is typically administered in a single session but can be given in as many as five sessions or fractions. By providing an ablative effect noninvasively, SRS has altered the treatment paradigms for benign and malignant intracranial tumors, functional disorders, and vascular malformations. Literature on extensive intracranial radiosurgery has unequivocally demonstrated the favorable benefit-to-risk profile that SRS affords for appropriately selected patients. In a departure from conventional radiotherapeutic strategies, radiosurgical principles have recently been extended to extracranial indications such as lung, spine, and liver tumors. The paradigm shift resulting from radiosurgery continues to alter the landscape of related fields. © 2014 by American Society of Clinical Oncology.

Rectal cancer: An evidence-based update for primary care providers

Rectal adenocarcinoma is an important cause of cancer-related deaths worldwide, and key anatomic differences between the rectum and the colon have significant implications for management of rectal cancer. Many advances have been made in the diagnosis and management of rectal cancer. These include clinical staging with imaging studies such as endorectal ultrasound and pelvic magnetic resonance imaging, operative approaches such as transanal endoscopic microsurgery and laparoscopic and robotic assisted proctectomy, as well as refined neoadjuvant and adjuvant therapies. For stage II and III rectal cancers, combined chemoradiotherapy offers the lowest rates of local and distant relapse, and is delivered neoadjuvantly to improve tolerability and optimize surgical outcomes, particularly when sphincter-sparing surgery is an endpoint. The goal in rectal cancer treatment is to optimize disease-free and overall survival while minimizing the risk of local recurrence and toxicity from both radiation and systemic therapy. Optimal patient outcomes depend on multidisciplinary involvement for tailored therapy. The successful management of rectal cancer requires a multidisciplinary approach, with the involvement of enterostomal nurses, gastroenterologists, medical and radiation oncologists, radiologists, pathologists and surgeons. The identification of patients who are candidates for combined modality treatment is particularly useful to optimize outcomes. This article provides an overview of the diagnosis, staging and multimodal therapy of patients with rectal cancer for primary care providers. PMID:26167068

From precision medicine to cancer care through the immunome: highlights from the European Society of Medical Oncology Congress, Madrid, 26-30th September 2014.

The recognition that cancer is a 'spectrum' of diseases, and that medical oncologists should achieve 'convergence' from 'divergence' to treat cancer patients was the main theme of the 2014 European Society of Medical Oncology (ESMO) Congress. The meeting assembled 19,859 participants from nearly 134 countries worldwide. The educational content was centered on precision medicine in cancer care, from mutational burden to the immunome, through the epigenome and the proteome. Precision medicine has been defined as the tailoring of medical treatment to the characteristics of an individual patient. Knowing an individual's genomics has created a remarkable and unprecedented opportunity to improve medical treatment and develop preventative strategies to preserve health. Clinical oncologists across the range of diseases recognise that for precision medicine to take hold, it will require intensive, rigorous validation that these new approaches do indeed improve patient outcomes. Not all molecular alterations are predictive of response to a specific targeted treatment nor are they all druggable, raising issues of cost-benefit, validation of specific biomarkers, and of managing patient expectations. Addressing all these issues will be essential for the medical community to embrace any given opportunities. Along with it, it will also require educational programmes that squarely address the knowledge chasm that currently exists for practicing physicians. The promise of genomic and precision medicine has created greater demands for both those providing the scientific expertise-bioinformatics, statisticians, molecular biologists-and those delivering clinical care-physicians, nurses, psychologists-to the patients. This ESMO 2014 report will highlight the major findings of this outstanding meeting.

Solar UV-radiation, vitamin D and skin cancer surveillance in organ transplant recipients (OTRs).

PubMed

Reichrath, Jörg; Nürnberg, Bernd

2008-01-01

The introduction of organ transplantation in clinical medicine has resulted in a constantly increasing, large population of patients that are chronically on immunosuppressive medication. It is well known that skin cancer, especially SCC, in this population has higher incidence rates, behaves more aggressively and has higher rates of metastasis. OTRs who have been treated for many years with immunosuppressive medication are at the highest risk for developing malignant skin tumors. Therefore, the intensity of surveillance for cutaneous lesions is of high importance in OTRs. A full-body skin exam at least once a year and more frequently if skin cancer or precancerous cutaneous lesions develop is recommended. Clinicians should not hesitate to biopsy or to surgically excise any suspicious skin lesion. Of high importance is also the education of OTRs about their increased risk. Protection against solar and artificial UV-radiation and monthly self-examinations are good ways to prevent and to recognize any new suspicious skin lesions. Patients are advised to always wear solar UV-radiation protection (e.g., clothing, sunscreen) before going outdoors. However, investigations have revealed that solar UV-B-exposure and serum 25(OH)D levels positively correlate with decreased risk for various internal malignancies (e.g., breast, colon, prostate and ovarian cancer) and other severe diseases. As we have shown previously, renal transplant recipients are at high risk of vitamin D deficiency. A sunscreen with a sun protection factor (SPF)-8 reduces the skin's production of vitamin D by 95%. Clothing completely blocks all solar UVB-radiation and this prevents any vitamin D production. Therefore, it is important to detect and treat vitamin D deficiency in solid organ transplant recipients. Optimal management of these patients requires communication between the transplant teams and the treating dermatologist and other clinicians. For advanced or metastatic disease, collaboration between clinicians of different disciplines, including the transplant team, dermatologists and radiation oncologists is also essential. In the future, dermatology clinics that are integrated into transplant centers may make it easier to manage and to treat OTRs, may make an interdisciplinary approach more effective and may thereby improve the clinical outcome in OTRs.

Oncology is undergoing profound change with the development of treatments and techniques, the evolution of care taking (outpatient, overall patient care, prevention and screening), attracting more and more women. This field is also concerned by the medical demography issue. Each professional team organisation and functions are meant to be reconsidered. We took interest in the general practitioner functions in cancer centers (they are present in 80% of those); a new concept which has not been studied in France yet. A questionnaire survey of general practitioners, oncologists and directors from 19 regional cancer centers and 9 private cancer clinics, was conducted during summer 2008. The overall response rate was 51% (260/512). This study aimed to underline the general practitioner main functions, who is widely qualified, with high relational ability, a role different from family physicians and oncologists, but closely working together with them, with hardly recognized specific activities: overall patient care, continuous care with the daily management of hospitalized patients allowing a reduction in oncologists working load, the continuity of care with the family physician, the involvement in the day hospital management, in the emergency department, in outpatient palliative care consultations and follow-up consultations.

Objective To explore perceptions of primary care physicians’ (PCPs) and oncologists’ roles, responsibilities, and patterns of communication related to shared cancer care in three integrated health systems that used electronic health records (EHRs). Study design Qualitative study. Methods We conducted semi-structured interviews with ten early stage colorectal cancer patients and fourteen oncologists and PCPs. Sample sizes were determined by thematic saturation. Dominant themes and codes were identified and subsequently applied to all transcripts. Results Physicians reported that EHRs improved communication within integrated systems, but communication with physicians outside their system was still difficult. PCPs expressed uncertainty about their role during cancer care, even though medical oncologists emphasized the importance of co-morbidity control during cancer treatment. Both patients and physicians described additional roles for PCPs, including psychological distress support and behavior modification. Conclusions Integrated systems that use EHRs likely facilitate shared cancer care through improved PCP-oncologist communication. However, strategies to facilitate a more active role for PCPs in managing co-morbidities, psychological distress and behavior modification, as well as to overcome communication challenges between physicians not practicing within the same integrated system, are still needed to improve shared cancer care.

Lung cancer: diagnosis, treatment principles, and screening.

PubMed

Latimer, Kelly M; Mott, Timothy F

2015-02-15

Lung cancer is classified histologically into small cell and non-small cell lung cancers. The most common symptoms of lung cancer are cough, dyspnea, hemoptysis, and systemic symptoms such as weight loss and anorexia. High-risk patients who present with symptoms should undergo chest radiography. If a likely alternative diagnosis is not identified, computed tomography and possibly positron emission tomography should be performed. If suspicion for lung cancer is high, a diagnostic evaluation is warranted. The diagnostic evaluation has three simultaneous steps (tissue diagnosis, staging, and functional evaluation), all of which affect treatment planning and determination of prognosis. The least invasive method possible should be used. The diagnostic evaluation and treatment of a patient with lung cancer require a team of specialists, including a pulmonologist, medical oncologist, radiation oncologist, pathologist, radiologist, and thoracic surgeon. Non-small cell lung cancer specimens are tested for various mutations, which, if present, can be treated with new targeted molecular therapies. The family physician should remain involved in the patient's care to ensure that the values and wishes of the patient and family are considered and, if necessary, to coordinate end-of-life care. Early palliative care improves quality of life and may prolong survival. Family physicians should concentrate on early recognition of lung cancer, as well as prevention by encouraging tobacco cessation at every visit. The U.S. Preventive Services Task Force recommends lung cancer screening using low-dose computed tomography in high-risk patients. However, the American Academy of Family Physicians concludes that the evidence is insufficient to recommend for or against screening. Whether to screen high-risk patients should be a shared decision between the physician and patient.

We sought to develop a core set of clinical indicators to enable international benchmarking of localized prostate cancer management using data available in the TrueNTH (True North) Global Registry. An international expert panel completed an online survey and participated in a face to face meeting. Participants included 3 urologists, 3 radiation oncologists, 2 psychologists, 1 medical oncologist, 1 nurse and 1 epidemiologist with prostate cancer expertise from a total of 7 countries. Current guidelines on prostate cancer treatment and potential quality indicators were identified from a literature review. These potential indicators were refined and developed through a modified Delphi process during which each panelist independently and repeatedly rated each indicator based on importance (satisfying the indicator demonstrated a provision of high quality care) and feasibility (the likelihood that data used to construct the indicator could be collected at a population level). The main outcome measure was items with panel agreement indicted by a disagreement index less 1, median importance 8.5 or greater and median feasibility 9 or greater. The expert panel endorsed 33 indicators. Seven of these 33 prostate cancer quality indicators assessed care relating to diagnosis, 7 assessed primary treatment, 1 assessed salvage treatment and 18 assessed health outcomes. We developed a set of quality indicators to measure prostate cancer care using numerous international evidence-based clinical guidelines. These indicators will be pilot tested in the TrueNTH Global Registry. Reports comparing indicator performance will subsequently be distributed to groups at participating sites with the purpose of improving the consistency and quality of prostate cancer management on a global basis.

HIV-infected individuals with non-AIDS-defining cancers are less likely to receive cancer treatment compared with uninfected individuals. We sought to identify provider-level factors influencing the delivery of oncology care to HIV-infected patients. A survey was mailed to 500 randomly selected US medical and radiation oncologists. The primary outcome was delivery of standard treatment, assessed by responses to three specialty-specific management questions. We used the χ(2) test to evaluate associations between delivery of standard treatment, provider demographics, and perceptions of HIV-infected individuals. Multivariable logistic regression identified associations using factor analysis to combine several correlated survey questions. Our response rate was 60%; 69% of respondents felt that available cancer management guidelines were insufficient for the care of HIV-infected patients with cancer; 45% never or rarely discussed their cancer management plan with an HIV specialist; 20% and 15% of providers were not comfortable discussing cancer treatment adverse effects and prognosis with their HIV-infected patients with cancer, respectively; 79% indicated that they would provide standard cancer treatment to HIV-infected patients. In multivariable analysis, physicians comfortable discussing adverse effects and prognosis were more likely to provide standard cancer treatment (adjusted odds ratio, 1.52; 95% CI, 1.12 to 2.07). Physicians with concerns about toxicity and efficacy of treatment were significantly less likely to provide standard cancer treatment (adjusted odds ratio, 0.67; 95% CI, 0.53 to 0.85). Provider-level factors are associated with delivery of nonstandard cancer treatment to HIV-infected patients. Policy change, provider education, and multidisciplinary collaboration are needed to improve access to cancer treatment. Copyright © 2015 by American Society of Clinical Oncology.

Abstract Background. The Macdonald criteria and the Response Assessment in Neuro-Oncology (RANO) criteria define radiologic parameters to classify therapeutic outcome among patients with malignant glioma and specify that clinical status must be incorporated and prioritized for overall assessment. But neither provides specific parameters to do so. We hypothesized that a standardized metric to measure neurologic function will permit more effective overall response assessment in neuro-oncology. Methods. An international group of physicians including neurologists, medical oncologists, radiation oncologists, and neurosurgeons with expertise in neuro-oncology drafted the Neurologic Assessment in Neuro-Oncology (NANO) scale as an objective and quantifiable metric of neurologic function evaluable during a routine office examination. The scale was subsequently tested in a multicenter study to determine its overall reliability, inter-observer variability, and feasibility. Results. The NANO scale is a quantifiable evaluation of 9 relevant neurologic domains based on direct observation and testing conducted during routine office visits. The score defines overall response criteria. A prospective, multinational study noted a >90% inter-observer agreement rate with kappa statistic ranging from 0.35 to 0.83 (fair to almost perfect agreement), and a median assessment time of 4 minutes (interquartile range, 3–5). Conclusion. The NANO scale provides an objective clinician-reported outcome of neurologic function with high inter-observer agreement. It is designed to combine with radiographic assessment to provide an overall assessment of outcome for neuro-oncology patients in clinical trials and in daily practice. Furthermore, it complements existing patient-reported outcomes and cognition testing to combine for a global clinical outcome assessment of well-being among brain tumor patients. PMID:28453751

The Case Volume Issue in Head and Neck Oncology.

PubMed

Alfieri, Salvatore; Orlandi, Ester; Bossi, Paolo

2017-10-27

In the past few years, several evidences reported better outcomes, in terms of reduced toxicities and longer survival, for head and neck cancer (HNC) patients when "regionalized," namely if they are managed at "high-volume" cancer referral centers (CRC). The benefit of case volume has been demonstrated in HNC patients primarily treated with surgery and in those receiving curative radiotherapy and chemotherapy. Many factors could explain these positive results: organization, facilities, processes of care, quality assurance programs, professional expertise, technology, and patient referral bias. In other words, the "high volume" could be linked both to all hospital-related volume and to the expertise of each involved professional figure (e.g., surgeon, radiation oncologist, medical oncologist, etc.). In this context, it is still debatable whether there is a need to understand which one of these factors is more able to influence the final outcomes of HNC patients. Considering the complexity and heterogeneity of HNC, all of these aspects are likely to impact and plot each other. However, there is no consensus regarding the criteria and the cut-off used to define as "high" the case volume. Moreover, some limitations or biases of the regionalization process have to be highlighted: (1) personal and financial discomfort of patients, their caregivers, and families; (2) a frequent referral of the healthiest or youngest patients to CRC could change the survival outcomes; (3) potential higher difficulties for colleagues working outside of CRC in the emergency. Nevertheless, the case volume represents one of the factors impacting on the quality of the treatment itself, in terms of reduced toxicity and better treatment outcome. Therefore, it should be considered as a stratifying factor in randomized controlled trials for HNC patients.

The records of 208.777 (100%) clinical trials registered at ClinicalTrials.gov were downloaded on the 19th of February 2016. Phase II and III trials including patients with glioblastoma were selected for further classification and analysis. Based on the disease settings, trials were classified into three groups: newly diagnosed glioblastoma, recurrent disease and trials with no differentiation according to disease setting. Furthermore, we categorized trials according to the experimental interventions, the primary sponsor, the source of financial support and trial design elements. Trends were evaluated using the autoregressive integrated moving average model. Two hundred sixteen (0.1%) trials were selected for further analysis. Academic centers (investigator initiated trials) were recorded as primary sponsors in 56.9% of trials, followed by industry 25.9%. Industry was the leading source of monetary support for the selected trials in 44.4%, followed by 25% of trials with primarily academic financial support. The number of newly initiated trials between 2005 and 2015 shows a positive trend, mainly through an increase in phase II trials, whereas phase III trials show a negative trend. The vast majority of trials evaluate forms of different systemic treatments (91.2%). In total, one hundred different molecular entities or biologicals were identified. Of those, 60% were involving drugs specifically designed for central nervous system malignancies. Trials that specifically address radiotherapy, surgery, imaging and other therapeutic or diagnostic methods appear to be rare. Current research in glioblastoma is mainly driven or sponsored by industry, academic medical oncologists and neuro-oncologists, with the majority of trials evaluating forms of systemic therapies. Few trials reach phase III. Imaging, radiation therapy and surgical procedures are underrepresented in current trials portfolios. Optimization in research portfolio for glioblastoma is needed.

Hematopoietic cell transplantation (HCT) is an important curative treatment for children with high-risk hematologic malignancies and solid tumors, and increasingly, non-malignant diseases. Given improvements in care, there is a growing number of long-term survivors of pediatric HCT. Compared with non-transplanted childhood cancer survivors, HCT survivors have been shown to have a substantially increased burden of serious chronic conditions and impairments involving virtually every organ system and overall quality of life. This likely reflects the joint contributions of pre-transplant treatment exposures and organ dysfunction, the transplant conditioning regimen, and any post-transplant graft versus host disease (GVHD). In response, the Children’s Oncology Group (COG) has created Long-Term Follow-Up Guidelines (www.survivorshipguidelines.org) for survivors of childhood, adolescent, and young adult cancer, including those treated with HCT. Guidelines taskforces, consisting of HCT specialists, other pediatric oncologists, radiation oncologists, organ-specific subspecialists, nurses, social workers, other healthcare professionals, and patient advocates have systematically reviewed the literature with regards to late effects after childhood cancer and HCT since 2002, with the most recent review completed in 2013. For the most recent review cycle, over 800 articles from the medical literature relevant to childhood cancer and HCT survivorship were reviewed, including 586 original research articles. Provided here-in is an organ system-based overview that emphasizes the most relevant COG recommendations (with accompanying evidence grade) for the long-term follow-up care of childhood HCT survivors (regardless of current age) based on a rigorous review of the available evidence. These recommendations cover both autologous and allogeneic HCT survivors, those transplanted for non-malignant diseases, and those with a history of chronic GVHD. PMID:26802323

With recent improvements in the diagnosis and treatment of cancer, the number of childhood cancer survivors (CCSs) has been increasing in Japan. The importance of quality of life during the lifetime of CCSs has now been recognized, and the late effects of cancer treatments are essential and important issues. In this study we analyzed the endocrinological abnormalities of CCSs by retrospectively evaluating 122 outpatients (62 males and 60 females) who had been referred from pediatric oncologists to our follow-up clinic among 151 CCSs attending our hospital more than two years after their cancer treatment. Follow-up duration varied from 2 to 30 (median 8.0) years. Their average age was 17.3 (range 4-36, median 17.0) years, and 38 patients (31.1%) reached adulthood. Endocrinological abnormalities were found in 82 (67%) of 122 survivors. Gonadal dysfunction was observed in 60 patients (49%). Thirty-nine patients (32%) were short or grew at a slower rate. Twenty-six patients (21%) showed thyroid dysfunction. Other abnormalities were as follows: obesity in 20 patients (16%), leanness in 10 (8%), central diabetes insipidus in 11 (9%) and adrenocortical dysfunction in 9 (7%). Low bone mineral density was observed in 41 (42%) of 98 patients evaluated. These endocrinological abnormalities were caused by the combined effects of cancer itself and various treatments (chemotherapy, radiation therapy, surgery, and hematopoietic stem cell transplantation). Lifetime medical surveillance and continuous follow-up are necessary for CCSs, because treatment-related complications may occur during childhood and many years after the therapy as well. Endocrinologists should participate in long-term follow-up of these survivors in collaboration with pediatric oncologists.

During this enduring, learner-driven, interactive CME webseries, lung cancer specialists will address the science and targeted therapies for the MET pathway in non-small cell lung cancer. Over the past decade, research has evolved in the science of identifying targeted biological changes in DNA and individual cancer cells. Along with the advanced understanding of lung cancer mutations, has come the development of specific targeted therapies that improve patient outcomes. The first step in treating a patient with lung cancer is proper diagnosis and staging, applying to the principles of personalize medicine. Our current understanding of lung cancer is that of a collection of diseases individualized through specific mutations. This CME activity reviews the role of the pulmonologist and pathologist in proper tissue acquisition and analysis. This new era of personalized medicine and clinical research advances has changed the way clinicians evaluate and treat patients with lung cancer. The data on lung cancer cell mutations and newer targeted therapies have improved the progression free survival and quality of life of lung cancer patients. This CME activity is designed to present a practical overview of recent evidenced based data of MET targeted therapies for patients with lung cancer. As research continues to evolve, we continue to advance our understanding in the science of lung cancers involving the MET pathway. Evidenced based data supporting newer targeted therapeutics provides insight on applying treatment for optimal outcomes. This CME activity will focus on the individualized treatment strategies using practical decision making for patients with MET expression. This activity has been designed to meet the educational needs of medical oncologists, pathologists, radiation oncologists, surgeons, pulmonologists, internists, and other healthcare clinicians responsible for the care of patients with lung cancer.

Purpose Although predictive multiplex somatic genomic tests hold the potential to transform care by identifying targetable alterations in multiple cancer genes, little is known about how physicians will use such tests in practice. Participants and Methods Before the initiation of enterprise-wide multiplex testing at a major cancer center, we surveyed all clinically active adult cancer physicians to assess their current use of somatic testing, their attitudes about multiplex testing, and their genomic confidence. Results A total of 160 physicians participated (response rate, 61%): 57% were medical oncologists; 29%, surgeons; 14% radiation oncologists; 37%, women; and 83%, research principal investigators. Twenty-two percent of physicians reported low confidence in their genomic knowledge. Eighteen percent of physicians anticipated testing patients infrequently (≤ 10%), whereas 25% anticipate testing most patients (≥ 90%). Higher genomic confidence was associated with wanting to test a majority of patients (adjusted odds ratio [OR], 6.09; 95% CI, 2.1 to 17.5) and anticipating using actionable (adjusted OR, 2.46; 95% CI, 1.2 to 5.2) or potentially actionable (adjusted OR, 2.89; 95% CI, 1.1 to 7.9) test results to inform treatment recommendations. Forty-two percent of physicians endorsed disclosure of uncertain genomic findings to patients. Conclusion Physicians at a tertiary-care National Cancer Institute–designated comprehensive cancer center varied considerably in how they planned to incorporate predictive multiplex somatic genomic tests into practice and in their attitudes about the disclosure of genomic information of uncertain significance. Given that many physicians reported low genomic confidence, evidence-based guidelines and enhanced physician genomic education efforts may be needed to ensure that genomically guided cancer care is adequately delivered.

Complementary and alternative medicine (CAM) has been widely used by cancer patients but rarely discussed by oncologists. This study was designed to evaluate the communication gap between China's oncologists and cancer patients on CAM. Two parallel cross-sectional studies assessed 83 oncologists and 402 cancer patients on CAM communication between patients and oncologists, and attitudes toward CAM use and clinical decisions about CAM. A majority (75.1%) of the cancer patients (302/402) were identified as CAM users within the most recent three months while 77.6% of the cancer patients (312/402) were identified as CAM users since diagnosis of cancer. Oncologists and patients responded differently ( P < .001) on CAM communications. Both oncologists and patients expected that CAM could improve the immune system. They both agreed that oncologists usually discouraged their patients from using CAM. Regarding the effectiveness of CAM, cancer patients were more likely to believe that CAM was effective while oncologists had more concerns about adverse effects of CAM use. CAM use by patients was predicted by disease duration (≥9 months) in the multivariable logistic regression model. China's oncologists and cancer patients may hold discrepant views on CAM. China's oncologists are encouraged to improve their knowledge on CAM and to initiate more discussions with their patients regarding effective and the safe use of CAM.

Objectives Describe the development and refinement of a scheme, Detail of Essential Elements and Participants in Shared Decision Making (DEEP-SDM), for coding Shared Decision Making (SDM) while reporting on the characteristics of decisions in a sample of patients with metastatic breast cancer. Methods The Evidence-Based Patient Choice instrument was modified to reflect Makoul and Clayman’s Integrative Model of SDM. Coding was conducted on video recordings of 20 women at the first visit with their medical oncologists after suspicion of disease progression. Noldus Observer XT v.8, a video coding software platform, was used for coding. Results The sample contained 80 decisions (range: 1-11), divided into 150 decision making segments. Most decisions were physician-led, although patients and physicians initiated similar numbers of decision-making conversations. Conclusion DEEP-SDM facilitates content analysis of encounters between women with metastatic breast cancer and their medical oncologists. Despite the fractured nature of decision making, it is possible to identify decision points and to code each of the Essential Elements of Shared Decision Making. Further work should include application of DEEP-SDM to non-cancer encounters. Practice Implications: A better understanding of how decisions unfold in the medical encounter can help inform the relationship of SDM to patient-reported outcomes. PMID:22784391

Impact of pixel-based machine-learning techniques on automated frameworks for delineation of gross tumor volume regions for stereotactic body radiation therapy.

The aim of this study was to investigate the impact of pixel-based machine learning (ML) techniques, i.e., fuzzy-c-means clustering method (FCM), and the artificial neural network (ANN) and support vector machine (SVM), on an automated framework for delineation of gross tumor volume (GTV) regions of lung cancer for stereotactic body radiation therapy. The morphological and metabolic features for GTV regions, which were determined based on the knowledge of radiation oncologists, were fed on a pixel-by-pixel basis into the respective FCM, ANN, and SVM ML techniques. Then, the ML techniques were incorporated into the automated delineation framework of GTVs followed by an optimum contour selection (OCS) method, which we proposed in a previous study. The three-ML-based frameworks were evaluated for 16 lung cancer cases (six solid, four ground glass opacity (GGO), six part-solid GGO) with the datasets of planning computed tomography (CT) and 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT images using the three-dimensional Dice similarity coefficient (DSC). DSC denotes the degree of region similarity between the GTVs contoured by radiation oncologists and those estimated using the automated framework. The FCM-based framework achieved the highest DSCs of 0.79±0.06, whereas DSCs of the ANN-based and SVM-based frameworks were 0.76±0.14 and 0.73±0.14, respectively. The FCM-based framework provided the highest segmentation accuracy and precision without a learning process (lowest calculation cost). Therefore, the FCM-based framework can be useful for delineation of tumor regions in practical treatment planning. Copyright © 2017 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

Purpose There has been much recent interest in promoting gender equality in academic medicine. This study aims to analyze gender differences in rank, career duration, publication productivity and research funding among radiation oncologists at U.S. academic institutions. Methods For 82 domestic academic radiation oncology departments, the authors identified current faculty and recorded their academic rank, degree and gender. The authors recorded bibliographic metrics for physician faculty from a commercially available database (SCOPUS, Elsevier BV, Amsterdam, NL), including numbers of publications and h-indices. The authors then concatenated this data with National Institute of Health funding for each individual per Research Portfolio Online Reporting Tools (REPORTer). The authors performed descriptive and correlative analyses, stratifying by gender and rank. Results Of 1031 faculty, 293 (28%) women and 738 (72%) men, men had a higher median h-index (8 (0-59) versus 5 (0-39); P<.05) and publication number (26 (0-591) versus 13 (0-306); P<.05) overall, and were more likely to be senior faculty and receive NIH funding. However, after stratifying for rank, these differences were largely non-significant. On multivariate analysis, there were significant correlations between gender, career duration and academic position, and h-index (P<.01). Conclusions The determinants of a successful career in academic medicine are certainly multi-factorial, particularly in traditionally male-dominated fields. However, data from radiation oncologists show a systematic gender association withfewer women achieving senior faculty rank. However, women who achieve senior status have productivity metrics comparable to their male counterparts. This suggests early career development and mentorship of female faculty may narrow productivity disparities. PMID:24667510

Purpose: To evaluate trends in the geographic distribution of the radiation oncology (RO) workforce. Methods and Materials: We used the 1995 and 2007 versions of the Area Resource File to map the ratio of RO to the population aged 65 years or older (ROR) within different health service areas (HSA) within the United States. We used regression analysis to find associations between population variables and 2007 ROR. We calculated Gini coefficients for ROR to assess the evenness of RO distribution and compared that with primary care physicians and total physicians. Results: There was a 24% increase in the RO workforcemore » from 1995 to 2007. The overall growth in the RO workforce was less than that of primary care or the overall physician workforce. The mean ROR among HSAs increased by more than one radiation oncologist per 100,000 people aged 65 years or older, from 5.08 per 100,000 to 6.16 per 100,000. However, there remained consistent geographic variability concerning RO distribution, specifically affecting the non-metropolitan HSAs. Regression analysis found higher ROR in HSAs that possessed higher education (p = 0.001), higher income (p < 0.001), lower unemployment rates (p < 0.001), and higher minority population (p = 0.022). Gini coefficients showed RO distribution less even than for both primary care physicians and total physicians (0.326 compared with 0.196 and 0.292, respectively). Conclusions: Despite a modest growth in the RO workforce, there exists persistent geographic maldistribution of radiation oncologists allocated along socioeconomic and racial lines. To solve problems surrounding the RO workforce, issues concerning both gross numbers and geographic distribution must be addressed.« less

The aim of this study was to identify the effects of a communication skills training (CST) program for oncologists, developed based on patient preferences regarding oncologists' communication. Thirty oncologists were randomly assigned to either an intervention group (IG; 2-day CST workshop) or control group (CG). Participants were assessed on their communication performance during simulated consultation and their confidence in communicating with patients at baseline and follow-up. A total of 1,192 patients (response rate, 84.6%) who had consultations with the participating oncologists at baseline and/or follow-up were assessed regarding their distress using the Hospital Anxiety and Depression Scale, satisfaction with the consultation, and trust in their oncologist after the consultation. At the follow-up survey, the performance scores of the IG had improved significantly, in terms of their emotional support (P = .011), setting up a supportive environment (P = .002), and ability to deliver information (P = .001), compared with those of the CG. Oncologists in the IG were rated higher at follow-up than those in the CG in terms of their confidence in themselves (P = .001). Patients who met with oncologists after they had undergone the CST were significantly less depressed than those who met with oncologists in the CG (P = .027). However, the CST program did not affect patient satisfaction with oncologists' style of communication. A CST program based on patient preferences is effective for both oncologists and patients with cancer. Oncologists should consider CST as an approach to enhancing their communication skills. © 2014 by American Society of Clinical Oncology.

Decision making is a highly complex task when providing care for seriously ill children. Physicians, parents, and children face many challenges when identifying and selecting from available treatment options. This qualitative interview study explored decision-making processes for children with cancer at different stages in their treatment in Switzerland and Romania. Thematic analysis of interviews conducted with parents and oncologists identified decision making as a heterogeneous process in both countries. Various decisions were made based on availability and reasonableness of care options. In most cases, at the time of diagnosis, parents were confronted with a "choiceless choice"-that is, there was only one viable option (a standard protocol), and physicians took the lead in making decisions significant for health outcomes. Parents' and sometimes children's role increased during treatment when they had to make decisions regarding research participation and aggressive therapy or palliative care. Framing these results within the previously described Decisional Priority in Pediatric Oncology Model (DPM) highlights family's more prominent position when making elective decisions regarding quality-of-life or medical procedures, which had little effect on health outcomes. The interdependency between oncologists, parents, and children is always present. Communication, sharing of information, and engaging in discussions about preferences, values, and ultimately care goals should be decision making's foundation. Patient participation in these processes was reported as sometimes limited, but parents and oncologists should continue to probe patients' abilities and desire to be involved in decision making. Future research should expand the DPM and explore how decisional priority and authority can be shared by oncologists with parents and even patients.

Cancer Care and Control as a Human Right: Recognizing Global Oncology as an Academic Field.

2017-01-01

The global burden of cancer incidence and mortality is on the rise. There are major differences in cancer fatality rates due to profound disparities in the burden and resource allocation for cancer care and control in developed compared with developing countries. The right to cancer care and control should be a human right accessible to all patients with cancer, regardless of geographic or economic region, to avoid unnecessary deaths and suffering from cancer. National cancer planning should include an integrated approach that incorporates a continuum of education, prevention, cancer diagnostics, treatment, survivorship, and palliative care. Global oncology as an academic field should offer the knowledge and skills needed to efficiently assess situations and work on solutions, in close partnership. We need medical oncologists, surgical oncologists, pediatric oncologists, gynecologic oncologists, radiologists, and pathologists trained to think about well-tailored resource-stratified solutions to cancer care in the developing world. Moreover, the multidisciplinary fundamental team approach needed to treat most neoplastic diseases requires coordinated investment in several areas. Current innovative approaches have relied on partnerships between academic institutions in developed countries and local governments and ministries of health in developing countries to provide the expertise needed to implement effective cancer control programs. Global oncology is a viable and necessary field that needs to be emphasized because of its critical role in proposing not only solutions in developing countries, but also solutions that can be applied to similar challenges of access to cancer care and control faced by underserved populations in developed countries.

Purpose To evaluate the personal and professional characteristics associated with career satisfaction and burnout among US oncologists. Methods Between October 2012 and March 2013, the American Society of Clinical Oncology conducted a survey of US oncologists evaluating burnout and career satisfaction. The survey sample included equal numbers of men and women and represented all career stages. Results Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys (median age of respondents, 52 years; 49.6% women). Among the 1,117 oncologists (37.3% of overall sample) who completed full-length surveys, 377 (33.8%) were in academic practice (AP) and 482 (43.2%) in private practice (PP), with the remainder in other settings. Oncologists worked an average of 57.6 hours per week (AP, 58.6 hours per week; PP, 62.9 hours per week) and saw a mean of 52 outpatients per week. Overall, 484 oncologists (44.7%) were burned out on the emotional exhaustion and/or depersonalization domain of Maslach Burnout Inventory (AP, 45.9%; PP, 50.5%; P = .18). Hours per week devoted to direct patient care was the dominant professional predictor of burnout for both PP and AP oncologists on univariable and multivariable analyses. Although a majority of oncologists were satisfied with their career (82.5%) and specialty (80.4%) choices, both measures of career satisfaction were lower for those in PP relative to AP (all P < .006). Conclusion Overall career satisfaction is high among US oncologists, albeit lower for those in PP relative to AP. Burnout rates among oncologists seem similar to those described in recent studies of US physicians in general. Those oncologists who devote the greatest amount of their professional time to patient care seem to be at greatest risk for burnout. PMID:24470006

Spinal instability is an acknowledged complication of spinal metastases; in spite of recent suggested criteria, it is not clearly defined in the literature. This study aimed to assess intra and interobserver agreement when using the Spine Instability Neoplastic Score (SINS) by all physicians involved in its management. Independent multicenter reliability study for the recently created SINS, undertaken with a panel of medical oncologists, neurosurgeons, radiologists, orthopedic surgeons, and radiation oncologists, was carried out. Ninety patients with biopsy-proven spinal metastases and magnetic resonance imaging, reviewed at the multidisciplinary tumor board of our institution, were included. Intraclass correlation coefficient (ICC) was used for SINS score agreement. Fleiss kappa statistic was used to assess agreement on the location of the most affected vertebral level; agreement on the SINS category ("stable," "potentially stable," or "unstable"); and overall agreement with the classification established by tumor board. Clinical data and imaging were provided to 83 specialists in 44 hospitals across 14 Spanish regions. No assessment criteria were pre-established. Each clinician assessed the SINS score twice, with a minimum 6-week interval. Clinicians were blinded to assessments made by other specialists and to their own previous assessment. Subgroup analyses were performed by clinicians' specialty, experience (≤7, 8-13, ≥14 years), and hospital category (four levels according to size and complexity). This study was supported by Kovacs Foundation. Intra and interobserver agreement on the location of the most affected levels was "almost perfect" (κ>0.94). Intra-observer agreement on the SINS score was "excellent" (ICC=0.77), whereas interobserver agreement was "moderate" (ICC=0.55). Intra-observer agreement in SINS category was "substantial" (k=0.61), whereas interobserver agreement was "moderate" (k=0.42). Overall agreement with the tumor board classification was "substantial" (κ=0.61). Results were similar across specialties, years of experience, and hospital category. Agreement on the assessment of metastatic spine instability is moderate. The SINS can help improve communication among clinicians in oncology care. Copyright © 2015 Elsevier Inc.

[Chaos theory: a fascinating concept for oncologists].

PubMed

Denis, F; Letellier, C

2012-05-01

The oncologist is confronted daily by questions related to the fact that any patient presents a specific evolution for his cancer: he is challenged by very different, unexpected and often unpredictable outcomes, in some of his patients. The mathematical approach used today to describe this evolution has recourse to statistics and probability laws: such an approach does not ultimately apply to one particular patient, but to a given more or less heterogeneous population. This approach therefore poorly characterizes the dynamics of this disease and does not allow to state whether a patient is cured, to predict if he will relapse and when this could occur, and in what form, nor to predict the response to treatment and, in particular, to radiation therapy. Chaos theory, not well known by oncologists, could allow a better understanding of these issues. Developed to investigate complex systems producing behaviours that cannot be predicted due to a great sensitivity to initial conditions, chaos theory is rich of suitable concepts for a new approach of cancer dynamics. This article is three-fold: to provide a brief introduction to chaos theory, to clarify the main connecting points between chaos and carcinogenesis and to point out few promising research perspectives, especially in radiotherapy.

As the only oncologists that provide both medical and surgical oncologic care, gynecologic oncologists encounter an exceptionally broad range of indications for prescribing opioids, from management of acute post-operative pain to chronic cancer-related pain to end-of-life care. If we are to balance opioid efficacy, safety and accessibility for our patients, we must be intimately familiar with appropriate clinical use of opioids in a range of settings, and engage in the national conversation around opioid misuse and how associated regulations and legislation may impact us and our patients. This article examines the appropriate use of opioids across the range of clinical settings encountered in gynecologic oncology. Copyright © 2018 Elsevier Inc. All rights reserved.

SU-F-T-247: Collision Risks in a Modern Radiation Oncology Department: An Efficient Approach to Failure Modes and Effects Analysis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schubert, L; Westerly, D; Vinogradskiy, Y

Purpose: Collisions between treatment equipment and patients are potentially catastrophic. Modern technology now commonly involves automated remote motion during imaging and treatment, yet a systematic assessment to identify and mitigate collision risks has yet to be performed. Failure modes and effects analysis (FMEA) is a method of risk assessment that has been increasingly used in healthcare, yet can be resource intensive. This work presents an efficient approach to FMEA to identify collision risks and implement practical interventions within a modern radiation therapy department. Methods: Potential collisions (e.g. failure modes) were assessed for all treatment and simulation rooms by teams consistingmore » of physicists, therapists, and radiation oncologists. Failure modes were grouped into classes according to similar characteristics. A single group meeting was held to identify implementable interventions for the highest priority classes of failure modes. Results: A total of 60 unique failure modes were identified by 6 different teams of physicists, therapists, and radiation oncologists. Failure modes were grouped into four main classes: specific patient setups, automated equipment motion, manual equipment motion, and actions in QA or service mode. Two of these classes, unusual patient setups and automated machine motion, were identified as being high priority in terms severity of consequence and addressability by interventions. The two highest risk classes consisted of 33 failure modes (55% of the total). In a single one hour group meeting, 6 interventions were identified. Those interventions addressed 100% of the high risk classes of failure modes (55% of all failure modes identified). Conclusion: A class-based approach to FMEA was developed to efficiently identify collision risks and implement interventions in a modern radiation oncology department. Failure modes and interventions will be listed, and a comparison of this approach against traditional FMEA methods will be presented.« less

Purpose: Late toxicities and cosmetic analyses of patients treated with accelerated partial breast irradiation (APBI) on RTOG 0319 are presented. Methods and Materials: Patients with stages I to II breast cancer ≤3 cm, negative margins, and ≤3 positive nodes were eligible. Patients received three-dimensional conformal external beam radiation therapy (3D-CRT; 38.5 Gy in 10 fractions twice daily over 5 days). Toxicity and cosmesis were assessed by the patient (P), the radiation oncologist (RO), and the surgical oncologist (SO) at 3, 6, and 12 months from the completion of treatment and then annually. National Cancer Institute Common Terminology Criteria for Adversemore » Events, version 3.0, was used to grade toxicity. Results: Fifty-two patients were evaluable. Median follow-up was 5.3 years (range, 1.7-6.4 years). Eighty-two percent of patients rated their cosmesis as good/excellent at 1 year, with rates of 64% at 3 years. At 3 years, 31 patients were satisfied with the treatment, 5 were not satisfied but would choose 3D-CRT again, and none would choose standard radiation therapy. The worst adverse event (AE) per patient reported as definitely, probably, or possibly related to radiation therapy was 36.5% grade 1, 50% grade 2, and 5.8% grade 3 events. Grade 3 AEs were all skin or musculoskeletal-related. Treatment-related factors were evaluated to potentially establish an association with observed toxicity. Surgical bed volume, target volume, the number of beams used, and the use of bolus were not associated with late cosmesis. Conclusions: Most patients enrolled in RTOG 0319 were satisfied with their treatment, and all would choose to have the 3D-CRT APBI again.« less

Hoffman, D; Dyer, B; Kumaran Nair, C

Purpose: The Integral Quality Monitor (IQM), developed by iRT Systems GmbH (Koblenz, Germany) is a large-area, linac-mounted ion chamber used to monitor photon fluence during patient treatment. Our previous work evaluated the change of the ion chamber’s response to deviations from static 1×1 cm2 and 10×10 cm2 photon beams and other characteristics integral to use in external beam detection. The aim of this work is to simulate two external beam radiation delivery errors, quantify the detection of simulated errors and evaluate the reduction in patient harm resulting from detection. Methods: Two well documented radiation oncology delivery errors were selected formore » simulation. The first error was recreated by modifying a wedged whole breast treatment, removing the physical wedge and calculating the planned dose with Pinnacle TPS (Philips Radiation Oncology Systems, Fitchburg, WI). The second error was recreated by modifying a static-gantry IMRT pharyngeal tonsil plan to be delivered in 3 unmodulated fractions. A radiation oncologist evaluated the dose for simulated errors and predicted morbidity and mortality commiserate with the original reported toxicity, indicating that reported errors were approximately simulated. The ion chamber signal of unmodified treatments was compared to the simulated error signal and evaluated in Pinnacle TPS again with radiation oncologist prediction of simulated patient harm. Results: Previous work established that transmission detector system measurements are stable within 0.5% standard deviation (SD). Errors causing signal change greater than 20 SD (10%) were considered detected. The whole breast and pharyngeal tonsil IMRT simulated error increased signal by 215% and 969%, respectively, indicating error detection after the first fraction and IMRT segment, respectively. Conclusion: The transmission detector system demonstrated utility in detecting clinically significant errors and reducing patient toxicity/harm in simulated external beam delivery. Future work will evaluate detection of other smaller magnitude delivery errors.« less

Late toxicities and cosmetic analyses of patients treated with accelerated partial breast irradiation (APBI) on RTOG 0319 are presented. Patients with stages I to II breast cancer ≤3 cm, negative margins, and ≤3 positive nodes were eligible. Patients received three-dimensional conformal external beam radiation therapy (3D-CRT; 38.5 Gy in 10 fractions twice daily over 5 days). Toxicity and cosmesis were assessed by the patient (P), the radiation oncologist (RO), and the surgical oncologist (SO) at 3, 6, and 12 months from the completion of treatment and then annually. National Cancer Institute Common Terminology Criteria for Adverse Events, version 3.0, was used to grade toxicity. Fifty-two patients were evaluable. Median follow-up was 5.3 years (range, 1.7-6.4 years). Eighty-two percent of patients rated their cosmesis as good/excellent at 1 year, with rates of 64% at 3 years. At 3 years, 31 patients were satisfied with the treatment, 5 were not satisfied but would choose 3D-CRT again, and none would choose standard radiation therapy. The worst adverse event (AE) per patient reported as definitely, probably, or possibly related to radiation therapy was 36.5% grade 1, 50% grade 2, and 5.8% grade 3 events. Grade 3 AEs were all skin or musculoskeletal-related. Treatment-related factors were evaluated to potentially establish an association with observed toxicity. Surgical bed volume, target volume, the number of beams used, and the use of bolus were not associated with late cosmesis. Most patients enrolled in RTOG 0319 were satisfied with their treatment, and all would choose to have the 3D-CRT APBI again. Copyright © 2013. Published by Elsevier Inc.

Purpose: Rapid evolution of imaging technologies and their integration into radiation therapy practice demands that radiation oncology (RO) training curricula be updated. The purpose of this study was to develop an entry-to-practice image literacy competency profile. Methods and Materials: A list of 263 potential imaging competency items were assembled from international objectives of training. Expert panel eliminated redundant or irrelevant items to create a list of 97 unique potential competency items. An international 2-round Delphi process was conducted with experts in RO. In round 1, all experts scored, on a 9-point Likert scale, the degree to which they agreed anmore » item should be included in the competency profile. Items with a mean score ≥7 were included, those 4 to 6 were reviewed in round 2, and items scored <4 were excluded. In round 2, items were discussed and subsequently ranked for inclusion or exclusion in the competency profile. Items with >75% voting for inclusion were included in the final competency profile. Results: Forty-nine radiation oncologists were invited to participate in round 1, and 32 (65%) did so. Participants represented 24 centers in 6 countries. Of the 97 items ranked in round 1, 80 had a mean score ≥7, 1 item had a score <4, and 16 items with a mean score of 4 to 6 were reviewed and rescored in round 2. In round 2, 4 items had >75% of participants voting for inclusion and were included; the remaining 12 were excluded. The final list of 84 items formed the final competency profile. The 84 enabling competency items were aggregated into the following 4 thematic groups of key competencies: (1) imaging fundamentals (42 items); (2) clinical application (27 items); (3) clinical management (5 items); and (4) professional practice (10 items). Conclusions: We present an imaging literacy competency profile which could constitute the minimum training standards in radiation oncology residency programs.« less

Treatment Guidelines for Preoperative Radiation Therapy for Retroperitoneal Sarcoma: Preliminary Consensus of an International Expert Panel

DOE Office of Scientific and Technical Information (OSTI.GOV)

Baldini, Elizabeth H., E-mail: ebaldini@partners.org; Wang, Dian; Haas, Rick L.M.

Purpose: Evidence for external beam radiation therapy (RT) as part of treatment for retroperitoneal sarcoma (RPS) is limited. Preoperative RT is the subject of a current randomized trial, but the results will not be available for many years. In the meantime, many practitioners use preoperative RT for RPS, and although this approach is used in practice, there are no radiation treatment guidelines. An international expert panel was convened to develop consensus treatment guidelines for preoperative RT for RPS. Methods and Materials: An expert panel of 15 academic radiation oncologists who specialize in the treatment of sarcoma was assembled. A systematicmore » review of reports related to RT for RPS, RT for extremity sarcoma, and RT-related toxicities for organs at risk was performed. Due to the paucity of high-quality published data on the subject of RT for RPS, consensus recommendations were based largely on expert opinion derived from clinical experience and extrapolation of relevant published reports. It is intended that these clinical practice guidelines be updated as pertinent data become available. Results: Treatment guidelines for preoperative RT for RPS are presented. Conclusions: An international panel of radiation oncologists who specialize in sarcoma reached consensus guidelines for preoperative RT for RPS. Many of the recommendations are based on expert opinion because of the absence of higher level evidence and, thus, are best regarded as preliminary. We emphasize that the role of preoperative RT for RPS has not been proven, and we await data from the European Organization for Research and Treatment of Cancer (EORTC) study of preoperative radiotherapy plus surgery versus surgery alone for patients with RPS. Further data are also anticipated pertaining to normal tissue dose constraints, particularly for bowel tolerance. Nonetheless, as we await these data, the guidelines herein can be used to establish treatment uniformity to aid future assessments of efficacy and toxicity.« less

Abstract Sorafenib is the only Food and Drug Administration (FDA)-approved first-line therapy shown to have survival benefit for patients with advanced hepatocellular carcinoma (HCC). Patients with advanced HCC are often but not exclusively transferred from non-oncologists to oncologists to initiate systemic therapy. The objective of this study was to assess whether sorafenib prescribing by non-oncologists has any impact on utilization, adverse effects, cost or outcome. This was a retrospective cohort study utilizing data from patients prescribed sorafenib for HCC within Veterans Health Administration hospitals with 100% chart abstraction to confirm HCC diagnosis, identify prescribing provider specialty (oncology versus gastroenterology/hepatology), and obtain data required for cancer staging by the Barcelona Clinic Liver Cancer (BCLC) system. The primary outcome was overall survival from the time of sorafenib prescription. A total of 4903 patients who prescribed sorafenib for HCC were identified, for whom 340 patients (6.9%) were prescribed drug by a non-oncologist (Onc). BCLC Stage, age, Child–Turcotte–Pugh score, and comorbidity indices were similar between patients prescribed sorafenib by oncologists and non-oncologists. Oncologists more often discontinued sorafenib due to progression, whereas non-oncologists were more likely to continue sorafenib until death resulting in greater pill utilization and cost. Overall survival in both unadjusted and multivariable models showed no significant impact of prescriber type on survival (222 vs 217 days, P = .96), confirmed with propensity-matched subcohorts. Similar survival outcomes were observed for patients with HCC prescribed sorafenib by non-oncologists and oncologists, suggesting that non-oncologists with expertise in the management of HCC can safely and effectively administer sorafenib.

Hematopoietic cell transplantation (HCT) is an expensive, resource-intensive, and medically complicated modality for treatment of many hematologic disorders. A well-defined care coordination model through the continuum can help improve health care delivery for this high-cost, high-risk medical technology. In addition to the patients and their families, key stakeholders include not only the transplantation physicians and care teams (including subspecialists), but also hematologists/oncologists in private and academic-affiliated practices. Initial diagnosis and care, education regarding treatment options including HCT, timely referral to the transplantation center, and management of relapse and late medical or psychosocial complications after HCT are areas where the referring hematologists/oncologists play a significant role. Payers and advocacy and community organizations are additional stakeholders in this complex care continuum. In this article, we describe a care coordination framework for patients treated with HCT within the context of coordination issues in care delivery and stakeholders involved. We outline the challenges in implementing such a model and describe a simplified approach at the level of the individual practice or center. This article also highlights ongoing efforts from physicians, medical directors, payer representatives, and patient advocates to help raise awareness of and develop access to adequate tools and resources for the oncology community to deliver well-coordinated care to patients treated with HCT. Lastly, we set the stage for policy changes around appropriate reimbursement to cover all aspects of care coordination and generate successful buy-in from all stakeholders. PMID:29296802

Protocols including combination of surgery and radiotherapy are more and more frequent in the treatment of bone tumors of the spine. In metastatic disease, combination of surgery and radiotherapy is since long time accepted, as based on clinical evidence. In primary tumors, combination of surgery and radiotherapy can be considered in all the cases in which a satisfactory oncological margin cannot be achieved: high-grade malignancies, recurrent tumors, huge tumors expanding in an extracompartimental area, and when tumor-free margin requires unacceptable functional sacrifices. However, metal implants are an obstacle in the collaboration between surgeons and radiation oncologists. Carbon-fiber-reinforced polyethil-ether-ether-ketone (CFR-PEEK) composite implants could make easier and more effective the treatment as radiolucent and not interfering with ionizing radiation and accelerated particles. The purpose of this article is to report the preliminary results from a cohort of patients treated with CFR-PEEK and to evaluate the safety and the non-inferiority of the device respect the commonly used titanium implants. This study concerns an ambispective cohort series of 34 tumor patients (14 metastases and 20 primaries, most of them recurrent) submitted to thoracic and lumbar spine fixation with a CFR-PEEK composite implants. Oncologic surgery was palliative decompression and fixation in 9 cases, tumor excision in 21, and enbloc resection in 4. Data collected for this preliminary report were all intraoperative remarks, incidence of complications, changes in neurological status, local control, and survival. All the cases were followed 6-36 months (mean 13 months). Only one intraoperative screw breakage occurred out of 232 implanted screws. Pain control and neurological improvement were the early clinical results. Two sacral screws loosening were found at 9 and 12 months in multilevel constructs performed on multirecurrent tumors. Six local recurrences were early found thanks to the implant radiolucency. Radiation oncologists' opinion was favourable as concerning better treatment planning on CT and lacking of scattering effect during the treatment. No artifacts on imaging studies mean early local recurrence detection. For radiation oncologists, no artifacts on imaging studies mean easier planning and no scattering effect means more effective and safe radiotherapy, particularly when particles are used. Moreover, it seems that the clinical use of CFR-PEEK composite implants may be safe and at least comparable with the commonly used titanium implants in terms of intraoperative complications, stability at weight bearing and at functional recovery. Larger patient series and longer follow-up are required to confirm these data.

Background Professional guidelines have been developed to promote discussion between providers and newly diagnosed young adults with cancer about the possibility of cancer treatment-related infertility, but previous research suggests many young adults fail to receive this information. The aim of this study was to examine rates of and factors predictive of oncologists’ compliance with national guidelines for discussing potential treatment-related infertility with newly diagnosed young adults seen at an NCI-designated comprehensive cancer center. Methods We reviewed data from the electronic medical record for new clinic encounters between medical oncologists and young adults with cancer (ages 18–39) from 2010 to 2012. Data from oncologist discussions of fertility preservation were abstracted, as were patient (age, gender, race, ethnicity, cancer type) and oncologist (gender, graduation year from fellowship) characteristics. Results 1018 cases were reviewed with 454 patients (M=31.5 years old, 67.8% women) meeting inclusion criteria. Overall, 83% of patients were informed about potential treatment-related infertility with patients with breast cancer (85% informed), Hodgkin lymphoma (95% informed), Non-Hodgkin lymphoma (94% informed), leukemia (88% informed) or testicular cancer (100% informed) more likely to be informed than other cancer types (60%–74% informed). There was a significant effect for patient gender (OR=3.57, CI: 1.33, 9.60, p=0.012) with females being more likely to be informed than males. Conclusions Reported compliance with fertility preservation guidelines was greater than published rates. Higher compliance rates in female patients and in patients with cancers more common among young adults may reflect greater awareness of fertility-related concerns among these patients and their providers.

Datta, Niloy R., E-mail: niloyranjan.datta@ksa.ch; Heuser, Michael; Bodis, Stephan

Purpose: To propose a roadmap and explore the cost implications of establishing a teleradiotherapy network to provide comprehensive cancer care and capacity building in countries without access to radiation therapy. Methods and Materials: Ten low-income sub-Saharan countries with no current radiation therapy facilities were evaluated. A basic/secondary radiation therapy center (SRTC) with 2 teletherapy, 1 brachytherapy, 1 simulator, and a treatment planning facility was envisaged at a cost of 5 million US dollars (USD 5M). This could be networked with 1 to 4 primary radiation therapy centers (PRTC) with 1 teletherapy unit, each costing USD 2M. The numbers of PRTCsmore » and SRTCs for each country were computed on the basis of cancer incidence, assuming that a PRTC and SRTC could respectively treat 450 and 900 patients annually. Results: An estimated 71,215 patients in these countries will need radiation therapy in 2020. Stepwise establishment of a network with 99 PRTCs and 28 SRTCs would result in 155 teletherapy units and 96% access to radiation therapy. A total of 310 radiation oncologists, 155 medical physicists, and 465 radiation therapy technologists would be needed. Capacity building could be undertaken through telementoring by networking to various international institutions and professional societies. Total infrastructure costs would be approximately USD 860.88M, only 0.94% of the average annual gross domestic product of these 10 countries. A total of 1.04 million patients could receive radiation therapy during the 15-year lifespan of a teletherapy unit for an investment of USD 826.69 per patient. For the entire population of 218.32 million, this equates to USD 4.11 per inhabitant. Conclusion: A teleradiotherapy network could be a cost-contained innovative health care strategy to provide effective comprehensive cancer care through resource sharing and capacity building. The network could also be expanded to include other allied specialties. The proposal calls for active coordination between all national and international organizations backed up by strong geopolitical commitment and action from all stakeholders.« less

MO-C-BRB-05: Translating NIH funding to a [potential] clinical device in breast cancer radiation therapy

Yu, C.

Diagnostic radiology and radiation oncology are arguably two of the most technologically advanced specialties in medicine. The imaging and radiation medicine technologies in clinical use today have been continuously improved through new advances made in the commercial and academic research arenas. This symposium explores the translational path from research through clinical implementation. Dr. Pettigrew will start this discussion by sharing his perspectives as director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB). The NIBIB has focused on promoting research that is technological in nature and has high clinical impact. We are in the age of precision medicine, andmore » the technological innovations and quantitative tools developed by engineers and physicists working with physicians are providing innovative tools that increase precision and improve outcomes in health care. NIBIB funded grants lead to a very high patenting rate (per grant dollar), and these patents have higher citation rates by other patents, suggesting greater clinical impact, as well. Two examples of clinical translation resulting from NIH-funded research will be presented, in radiation therapy and diagnostic imaging. Dr. Yu will describe a stereotactic radiotherapy device developed in his laboratory that is designed for treating breast cancer with the patient in the prone position. It uses 36 rotating Cobalt-60 sources positioned in an annular geometry to focus the radiation beam at the system’s isocenter. The radiation dose is delivered throughout the target volume in the breast by constantly moving the patient in a planned trajectory relative to the fixed isocenter. With this technique, the focal spot dynamically paints the dose distribution throughout the target volume in three dimensions. Dr. Jackson will conclude this symposium by describing the RSNA Quantitative Imaging Biomarkers Alliance (QIBA), which is funded in part by NIBIB and is a synergistic collaboration between medical physicists, radiologists, oncologists, industry representatives, and other stakeholders. The mission of QIBA is to improve the accuracy and practicality of quantitative image-based biomarkers by increasing precision across devices, patients, and time, an essential step in incorporating quantitative imaging biomarkers into radiology practice. Validated quantitative imaging biomarkers are necessary to support precision medicine initiatives, multimodality / multiparametric applications in medicine, treatment planning and response assessment, and radiogenomics applications. Current applications in the QIBA portfolio extend to cancer diagnosis and treatment, pulmonary diseases, and neurological disorders. The overall goal of this symposium is to illustrate the bidirectional exchange between medical research and clinical practice. Revitalizing scientific excellence in clinical medical physics challenges practitioners to identify clinical limitations, which then drive research innovation; research funded by the NIH and other agencies develops technological solutions to these limitations, which are translated to the care environment to ultimately improve clinical practice in radiology and radiation oncology.« less

In recent years, chemotherapies have been further advanced because of successive launch of new drugs, introduction of molecular targeting, etc., and the concept of so-called Team Medical Care ,the idea of sharing interdisciplinary expertise for collaborative treatment, has steadily penetrated in the Japanese medical society. Dr. Naoto Ueno is a medical oncologist at US MD Anderson Cancer Center, the birthplace of the Team Medical Care. He has advocated the concept of ABC of Team Oncology by positioning pharmaceutical companies as Team C. Under such team practice, we believe that medical representatives of a pharmaceutical company should also play a role as a member of the Team Medical Care by providing appropriate drug use information to healthcare professionals, supporting post-marketing surveillance of treated patients, facilitating drug information sharing among healthcare professionals at medical institutions, etc.

This patterns of practice study was conducted on behalf of the RANZCR Breast Interest Group in order to document current radiotherapy practices for breast cancer in Australia and New Zealand. The survey identifies variations and highlights potential contentious aspects of radiotherapy management of breast cancer. A fifty-eight question survey was disseminated via the Survey Monkey digital platform to 388 Radiation Oncologists in Australia and New Zealand. In total, 156 responses were received and collated. Areas of notable consensus among respondents included hypofractionation (77.3% of respondents would 'always' or 'sometimes' consider hypofractionation in the management of ductal carcinoma in-situ and 99.3% in early invasive breast cancer); margin status in early breast cancer (73.8% believe a clear inked margin is sufficient and does not require further surgery) and use of bolus in post-mastectomy radiotherapy (PMRT) (91.1% of participants use bolus in PMRT). Areas with a wider degree of variability amongst respondents included regional nodal irradiation and components of radiotherapy planning and delivery (examples include the technique used for delivery of boost and frequency of bolus application for PMRT). The results of these patterns of practice survey informs radiation oncologists in Australia and New Zealand of the current clinical practices being implemented by their peers. The survey identifies areas of consensus and contention, the latter of which may lead to a development of research trials and/or educational activities to address these areas of uncertainty. © 2016 The Royal Australian and New Zealand College of Radiologists.

The ESTRO Health Economics in Radiation Oncology (HERO) project has the overall aim to develop a knowledge base of the provision of radiotherapy in Europe and build a model for health economic evaluation of radiation treatments at the European level. The first milestone was to assess the availability of radiotherapy resources within Europe. This paper presents the personnel data collected in the ESTRO HERO database. An 84-item questionnaire was sent out to European countries, through their national scientific and professional radiotherapy societies. The current report includes a detailed analysis of radiotherapy staffing (questionnaire items 47-60), analysed in relation to the annual number of treatment courses and the socio-economic status of the countries. The analysis was conducted between February and July 2014, and is based on validated responses from 24 of the 40 European countries defined by the European Cancer Observatory (ECO). A large variation between countries was found for most parameters studied. Averages and ranges for personnel numbers per million inhabitants are 12.8 (2.5-30.9) for radiation oncologists, 7.6 (0-19.7) for medical physicists, 3.5 (0-12.6) for dosimetrists, 26.6 (1.9-78) for RTTs and 14.8 (0.4-61.0) for radiotherapy nurses. The combined average for physicists and dosimetrists is 9.8 per million inhabitants and 36.9 for RTT and nurses. Radiation oncologists on average treat 208.9 courses per year (range: 99.9-348.8), physicists and dosimetrists conjointly treat 303.3 courses (range: 85-757.7) and RTT and nurses 76.8 (range: 25.7-156.8). In countries with higher GNI per capita, all personnel categories treat fewer courses per annum than in less affluent countries. This relationship is most evident for RTTs and nurses. Different clusters of countries can be distinguished on the basis of available personnel resources and socio-economic status. The average personnel figures in Europe are now consistent with, or even more favourable than the QUARTS recommendations, probably reflecting a combination of better availability as such, in parallel with the current use of more complex treatments than a decade ago. A considerable variation in available personnel and delivered courses per year however persists among the highest and lowest staffing levels. This not only reflects the variation in cancer incidence and socio-economic determinants, but also the stage in technology adoption along with treatment complexity and the different professional roles and responsibilities within each country. Our data underpin the need for accurate prediction models and long-term education and training programmes. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

To evaluate the learner's perspectives on a novel workshop programme designed to improve skills in biostatistics, research methodology and critical appraisal in oncology. Trainees were surveyed anonymously at the completion of each annual workshop from 2012 to 2015. In total, 103 trainees in years 2-4 of training in radiation oncology responded, giving a 94% survey response rate. A 1 day workshop, designed by biostatisticians and radiation oncologist facilitators, is the central component of a programme teaching skills in biostatistics, research methods and critical appraisal. This links short didactic lectures about statistical concepts to interactive trainee discussions around discipline-related publications. The workshop was run in conjunction with the major radiation oncology clinical trials group meeting with alternating programmes (A and B). Most of the participants (44-47/47 for A and 48-55/56 for B), reported that their understanding of one or more individual topics improved as a result of teaching. Refinement of the workshop over time led to a more favourable perception of the 'optimal' balance between didactic/interactive teaching: nine of 27 (33%) 'optimal' responses seen in 2013 compared with 23 of 29 (79%) in 2015 (P < 0.001). Commonly reported themes were: clinician facilitators and access to biostatisticians helped contextualise learning and small group, structured discussions provided an environment conducive to learning. Overall, radiation oncology trainees reported positive perceptions of the educational value of this programme, with feedback identifying areas where this resource might be improved. This model could readily be adapted to suit other medical disciplines and/or other training environments, using specialty-specific research to illuminate key statistical concepts.

Chittem, Mahati; Butow, Phyllis

2015-01-01

Nondisclosure of cancer diagnosis is common in many Eastern countries. Consequently, immigrant families often approach oncologists with requests for nondisclosure in Western countries. To explore differences in the attitudes and practices of Western-born and nonWestern born oncologists in Australia when faced with a nondisclosure request. Using a cross-sectional design, oncologists were interviewed over the telephone. Using the snowball method, 14 Australian (Western = 9, non-Western = 5) oncologists were recruited. Oncologists participated in a semi-structured interview exploring their experiences of, and response to, a request for nondisclosure, and their perceptions of how their cultural background influenced these attitudes and responses. The interviews were transcribed and analyzed using interpretative phenomenological analysis. Six main themes emerged from the study: (1) Barriers to truthful communication, (2) an ethical and moral dilemma, (3) high costs of nondisclosure, (4) cultural influences on interpretation and understanding of requests for nondisclosure, (5) emotional impact of bad news on patients, families and oncologists, and (6) truthful disclosure as a gentle balancing act. All oncologists felt that the family request for nondisclosure was difficult, with many cultural and emotional nuances to take into consideration. Some immigrant Australian oncologists who had a similar cultural background as the patient/family, felt they could better understand the desire for nondisclosure. Irrespective of their cultural background, all oncologists acknowledged that breaking bad news had to be done in a gentle, gradual manner. The study suggests a need to develop a culturally sensitive cancer communication model.

Cancer patients need to trust their oncologist to embark in the process of oncologic treatment. Yet, it is unclear how oncologist communication contributes to such trust. The aim of this study was to investigate the effect of three elements of oncologists' communication on cancer patients' trust: conferring competence, honesty, and caring. Eight videotaped consultations, 'vignettes', were created, reflecting an encounter between an oncologist and a patient with colorectal cancer. All vignettes were identical, except for small variations in the oncologist's verbal communication. Cancer patients (n = 345) were randomly assigned to viewing two vignettes, asked to identify with the patient and afterwards to rate their trust in the observed oncologist. The effects of competence, honesty, and caring on trust were established with multilevel analysis. Oncologist's enhanced expression of competence (β = 0.17, 95% CI 0.08, 0.27; P < 0.001), honesty (β = 0.30, 95% CI 0.20, 0.40; P < 0.001), as well as caring (β = 0.36, 95% CI 0.26, 0.46; P < 0.001) resulted in significantly increased trust. Communication of honesty and caring also increased patients' expectation of operation success and reported willingness to recommend the oncologist. As hypothesized, oncologists can influence their patients' trust by enhanced conveyance of their level of competence, honesty, and caring. Caring behavior has the strongest impact on trust. These findings can be translated directly into daily clinical practice as well as in communication skills training.

Purpose Patients who develop a strong alliance with their health care providers have been shown to have higher levels of psychosocial well-being and rates of treatment adherence. Young adults with cancer have lower levels of psychosocial well-being and treatment adherence relative to patients with cancer in other age groups. This study sought to evaluate the relationships between the patient-oncologist alliance, psychosocial well-being, and treatment adherence in young adults with advanced cancer. Patients and Methods Ninety-five young adults (age 20 to 40 years) with advanced cancer were administered measures of alliance, psychosocial well-being, willingness to adhere to treatment, and treatment adherence. Relationships between alliance and psychosocial well-being were examined bivariately. Multiple linear regression models examined the relationship between alliance and adherence, controlling for confounding influences (eg, psychosocial well-being). Results Alliance was significantly (P ≤ .01) and positively associated with greater perceived social support and less severe illness-related grief. After controlling for significant confounding influences (ie, metastases, appraised support, and grief), alliance remained significantly (P ≤ .01) associated with greater willingness to adhere to treatment and greater adherence to oral medication. Conclusion By developing a strong alliance, oncologists may enhance psychosocial well-being and increase treatment adherence in young adult patients with advanced cancer. PMID:23530105

Until the late 1980s, gastroenterology (GE) was considered a subspecialty of Internal Medicine. Today, GE also incorporates Hepatology. However, Digestive Oncology training is poorly defined in the Hepatogastroenterology (HGE)-curriculum. Therefore, a Digestive Oncology curriculum should be developed and this document might be a starting point for such a curriculum. HGE-specialists are increasingly resisting the paradigm in which they play only a diagnostic and technical role in the management of digestive tumors. We suggest minimum end-points in the standard HGE-curriculum for oncology, and recommend a focus year in the Netherlands for Digestive Oncology in the HGE-curriculum. To produce well-trained digestive oncologists, an advanced Digestive Oncology training program with specific qualifications in Digestive Oncology (2 years) has been developed. The schedule in Belgium includes a period of at least 6 mo to be spent in a medical oncology department. The goal of these programs remains the production of well-trained digestive oncologists. HGE specialists are part of the multidisciplinary oncological teams, and some have been administering chemotherapy in their countries for years. In this article, we provide a road map for the organization of a proper training in Digestive Oncology. We hope that the World Gastroenterology Organisation and other (inter)national societies will support the necessary certifications for this specific training in the HGE-curriculum. PMID:21556128

Cancer patients want access to reliable information about currently recruiting clinical trials. Oncologists and their patients were randomly assigned to access a consumer-friendly cancer clinical trials web site [Australian Cancer Trials (ACT), www.australiancancertrials.gov.au] or to usual care in a cluster randomized controlled trial. The primary outcome, measured from audio recordings of oncologist-patient consultations, was the proportion of patients with whom participation in any clinical trial was discussed. Analysis was by intention-to-treat accounting for clustering and stratification. Thirty medical oncologists and 493 patients were recruited. Overall, 46% of consultations in the intervention group compared with 34% in the control group contained a discussion about clinical trials (P=0.08). The mean consultation length in both groups was 29 min (P=0.69). The proportion consenting to a trial was 10% in both groups (P=0.65). Patients' knowledge about randomized trials was lower in the intervention than the control group (mean score 3.0 versus 3.3, P=0.03) but decisional conflict scores were similar (mean score 42 versus 43, P=0.83). Good communication between patients and physicians is essential. Within this context, a web site such as Australian Cancer Trials may be an important tool to encourage discussion about clinical trial participation.

Poor prognosis is difficult to impart, particularly across a cultural divide. This study compared prognostic communication with immigrants (with and without interpreters) versus native-born patients in audio-taped oncology consultations. Ten oncologists, 78 patients (31 Australian-born, 47 immigrants) and 115 family members participated. The first two consultations after diagnosis of incurable disease were audiotaped, transcribed and coded. 142 consultations were included in the analysis. Fifty percent of doctor and 59% of patient prognostic speech units were not interpreted or interpreted non-equivalently when an interpreter was present. Immigrant status predicted few prognostic facts, and oncologist characteristics no prognostic facts, disclosed. Oncologists were significantly less likely to convey hope to immigrants (p=0.0004), and more likely to use medical jargon (p=0.009) than with Australian-born patients. Incurable disease status and a limited life span were commonly acknowledged, generally with no timeframe provided. Physical issues were discussed more commonly than emotional aspects. While culture did not appear to influence doctor speech, interpreters filtered or blocked much prognostic communication. Initiatives to empower all patients to attain needed information, optimise communication when an interpreter is present and train cancer health professionals in culturally appropriate care, are urgently required.

The importance of outpatient cancer care services is increasing due to the growing number of patients having or having had cancer. However, little is known about cooperation among physicians in outpatient settings. To understand what inter- and multidisciplinary care means in community settings, we conducted an amplified secondary analysis that combined qualitative interview data with 42 general practitioners (GPs), 21 oncologists and 21 urologists that mainly worked in medical practices in Germany. We compared their perspectives on cooperation relationships in cancer care. Our results indicate that all participants regarded cooperation as a prerequisite for good cancer care. Oncologists and urologists mainly reported cooperating for tumour-specific treatment tasks, while GPs' reasoning for cooperation was more patient-centred. While oncologists and urologists reported experiencing reciprocal communication with other physicians, GPs had to gather the information they needed. GPs seldom reported engaging in formal cooperation structures, while for specialists, participation in formal spaces of cooperation, such as tumour boards, facilitated a more frequent and informal discussion of patients, for instance on the phone. Further research should focus on ways to foster GPs' integration in cancer care and evaluate if this can be reached by incorporating GPs in formal cooperation structures such as tumour boards. © 2017 John Wiley & Sons Ltd.

IMPORTANCE Patients with advanced cancer often report expectations for survival that differ from their oncologists’ expectations. Whether patients know that their survival expectations differ from those of their oncologists remains unknown. This distinction is important because knowingly expressing differences of opinion is important for shared decision making, whereas patients not knowing that their understanding differs from that of their treating physician is a potential marker of inadequate communication. OBJECTIVE To describe the prevalence, distribution, and proportion of prognostic discordance that is due to patients’ knowingly vs unknowingly expressing an opinion that differs from that of their oncologist. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional study conducted at academic and community oncology practices in Rochester, New York, and Sacramento, California. The sample comprises 236 patients with advanced cancer and their 38 oncologists who participated in a randomized trial of an intervention to improve clinical communication. Participants were enrolled from August 2012 to June 2014 and followed up until October 2015. MAIN OUTCOMES AND MEASURES We ascertained discordance by comparing patient and oncologist ratings of 2-year survival probability. For discordant pairs, we determined whether patients knew that their opinions differed from those of their oncologists by asking the patients to report how they believed their oncologists rated their 2-year survival. RESULTS Among the 236 patients (mean [SD] age, 64.5 [11.4] years; 54%female), 161 patient-oncologist survival prognosis ratings (68%; 95%CI, 62%–75%) were discordant. Discordance was substantially more common among nonwhite patients compared with white patients (95%[95%CI, 86%–100%] vs 65%[95%CI, 58%–73%], respectively; P = .03). Among 161 discordant patients, 144 (89%) did not know that their opinions differed from that of their oncologists and nearly all of them (155 of 161 [96%]) were more optimistic than their oncologists. CONCLUSIONS AND RELEVANCE In this study, patient-oncologist discordance about survival prognosis was common and patients rarely knew that their opinions differed from those of their oncologists.

OBJECTIVE Tumor quantification is essential for determining the clinical efficacy and response to established and evolving therapeutic agents in cancer trials. The purpose of this study was to seek the opinions of oncologists and radiologists about quantitative interactive and multimedia reporting. SUBJECTS AND METHODS Questionnaires were distributed to 253 oncologists and registrars and to 35 radiologists at our institution through an online survey application. Questions were asked about current reporting methods, methods for Response Evaluation Criteria in Solid Tumors (RECIST) tumor measurement, and preferred reporting format. RESULTS The overall response rates were 43.1% (109/253) for oncologists and 80.0% (28/35) for radiologists. The oncologists treated more than 40 tumor types. Most of the oncologists (65.7% [67/102]) and many radiologists (44.4% [12/27]) (p = 0.020) deemed the current traditional qualitative radiology reports insufficient for reporting tumor burden and communicating measurements. Most of the radiologists (77.8% [21/27]) and oncologists (85.5% [71/83]) (p = 0.95) agreed that key images with measurement annotations helped in finding previously measured tumors; however, only 43% of radiologists regularly saved key images. Both oncologists (64.2% [70/109]) and radiologists (67.9% [19/28]) (p = 0.83) preferred the ability to hyperlink measurements from reports to images of lesions as opposed to text-only reports. Approximately 60% of oncologists indicated that they handwrote tumor measurements on RECIST forms, and 40% used various digital formats. Most of the oncologists (93%) indicated that managing tumor measurements within a PACS would be superior to handwritten data entry and retyping of data into a cancer database. CONCLUSION Oncologists and radiologists agree that quantitative interactive reporting would be superior to traditional text-only qualitative reporting for assessing tumor burden in cancer trials. A PACS reporting system that enhances and promotes collaboration between radiologists and oncologists improves quantitative reporting of tumors. PMID:26295661

Increasing numbers of cancer survivors have driven a greater focus on care of cancer patients after treatment. Radiation oncologists have long considered follow-up of patients an integral part of practice. We sought to document current survivor-focused care patterns and identify barriers to meeting new regulatory commission guidelines for survivorship care plans (SCPs) and provide guidance for survivorship care. A 23-question electronic survey was e-mailed to all practicing US physician American Society of Radiation Oncology members. Responses were collected for 25 days in March 2014. Survey data were descriptively analyzed. A total of 574 eligible providers responded, for a response percentage of 14.7%. Almost all providers follow their patients after treatment (97%). Length of follow-up was frequently extensive: 17% followed up to 2 years, 40% for 3-5 years, 12% for 6-10 years, and 31% indefinitely. Ancillary services, particularly social work and nutrition services, are commonly available onsite to patients in follow-up. Fewer than half of respondents (40%) indicated that they currently use SCPs for curative intent patients and those who do generally use internally developed templates. SCPs typically go to patients (91%), but infrequently to primary care providers (22%). The top 3 barriers to implementation of SCPs were cost (57%), duplicative survivorship care plans provided by other physicians (43%), and lack of consensus or professional guidelines (40%). Eighty-seven percent indicated that SCPs built into an electronic medical record system would be useful. A significant part of radiation oncology practice includes the care of those in the surveillance of follow-up phase of care. SCPs may be beneficial in improving communication with the patient and other care but are not widely used within our field. This survey identified key barriers to use of SCPs and provides specialty guidance for important information to be included in a radiation oncology oriented SCP.

Prevention and Screening in Hereditary Breast and Ovarian Cancer.

PubMed

Zeichner, Simon B; Stanislaw, Christine; Meisel, Jane L

2016-10-15

In recent years, we have learned a great deal about pathogenic mutations that increase the risk of breast and ovarian cancer, particularly mutations in the BRCA1 and BRCA2 genes. Here we review current guidelines on breast and ovarian cancer screening, prophylactic surgery, and other risk-reduction strategies in patients with these mutations, and we detail the data that drive these recommendations. We also discuss guidelines on screening and management for other cancers associated with BRCA1 and BRCA2, such as male breast cancer, pancreatic cancer, and prostate cancer. Discussions about genetic testing have become more complex with the advent of panel testing, which often allows for testing of a more comprehensive panel of genes than traditional BRCA1 and BRCA2 testing, but which is also associated with a higher likelihood of obtaining results with less clear data to inform management. It is difficult to come to a consensus on how best to address the varied and potentially challenging situations that may arise from genetic testing. The complexity inherent in managing these cases makes a multidisciplinary team-including medical oncologists, surgical oncologists, genetic counselors, reproductive endocrinologists, and medical ethicists-critical to optimization of care.

Biological origins of sexual orientation and gender identity: Impact on health.

PubMed

O'Hanlan, Katherine A; Gordon, Jennifer C; Sullivan, Mackenzie W

2018-04-01

Gynecologic Oncologists are sometimes consulted to care for patients who present with diverse gender identities or sexual orientations. Clinicians can create more helpful relationships with their patients if they understand the etiologies of these diverse expressions of sexual humanity. Multidisciplinary evidence reveals that a sexually dimorphic spectrum of somatic and neurologic anatomy, traits and abilities, including sexual orientation and gender identity, are conferred together during the first half of pregnancy due to genetics, epigenetics and the diversity of timing and function of sex chromosomes, sex-determining protein secretion, gonadal hormone secretion, receptor levels, adrenal function, maternally ingested dietary hormones, fetal health, and many other factors. Multiple layers of evidence confirm that sexual orientation and gender identity are as biological, innate and immutable as the other traits conferred during that critical time in gestation. Negative social responses to diverse orientations or gender identities have caused marginalization of these individuals with resultant alienation from medical care, reduced self-care and reduced access to medical care. The increased risks for many diseases, including gynecologic cancers are reviewed. Gynecologic Oncologists can potentially create more effective healthcare relationships with their patients if they have this information. Copyright © 2017 Elsevier Inc. All rights reserved.

Deformable image registration based automatic CT-to-CT contour propagation for head and neck adaptive radiotherapy in the routine clinical setting

Purpose: To evaluate the clinical potential of deformable image registration (DIR)-based automatic propagation of physician-drawn contours from a planning CT to midtreatment CT images for head and neck (H and N) adaptive radiotherapy. Methods: Ten H and N patients, each with a planning CT (CT1) and a subsequent CT (CT2) taken approximately 3–4 week into treatment, were considered retrospectively. Clinically relevant organs and targets were manually delineated by a radiation oncologist on both sets of images. Four commercial DIR algorithms, two B-spline-based and two Demons-based, were used to deform CT1 and the relevant contour sets onto corresponding CT2 images. Agreementmore » of the propagated contours with manually drawn contours on CT2 was visually rated by four radiation oncologists in a scale from 1 to 5, the volume overlap was quantified using Dice coefficients, and a distance analysis was done using center of mass (CoM) displacements and Hausdorff distances (HDs). Performance of these four commercial algorithms was validated using a parameter-optimized Elastix DIR algorithm. Results: All algorithms attained Dice coefficients of >0.85 for organs with clear boundaries and those with volumes >9 cm{sup 3}. Organs with volumes <3 cm{sup 3} and/or those with poorly defined boundaries showed Dice coefficients of ∼0.5–0.6. For the propagation of small organs (<3 cm{sup 3}), the B-spline-based algorithms showed higher mean Dice values (Dice = 0.60) than the Demons-based algorithms (Dice = 0.54). For the gross and planning target volumes, the respective mean Dice coefficients were 0.8 and 0.9. There was no statistically significant difference in the Dice coefficients, CoM, or HD among investigated DIR algorithms. The mean radiation oncologist visual scores of the four algorithms ranged from 3.2 to 3.8, which indicated that the quality of transferred contours was “clinically acceptable with minor modification or major modification in a small number of contours.” Conclusions: Use of DIR-based contour propagation in the routine clinical setting is expected to increase the efficiency of H and N replanning, reducing the amount of time needed for manual target and organ delineations.« less

CCC meets ICU: redefining the role of critical care of cancer patients.

Currently the majority of cancer patients are considered ineligible for intensive care treatment and oncologists are struggling to get their patients admitted to intensive care units. Critical care and oncology are frequently two separate worlds that communicate rarely and thus do not share novel developments in their fields. However, cancer medicine is rapidly improving and cancer is eventually becoming a chronic disease. Oncology is therefore characterized by a growing number of older and medically unfit patients that receive numerous novel drug classes with unexpected side effects. All of these changes will generate more medically challenging patients in acute distress that need to be considered for intensive care. An intense exchange between intensivists, oncologists, psychologists and palliative care specialists is warranted to communicate the developments in each field in order to improve triage and patient treatment. Here, we argue that "critical care of cancer patients" needs to be recognized as a medical subspecialty and that there is an urgent need to develop it systematically. As prognosis of cancer improves, novel therapeutic concepts are being introduced and more and more older cancer patients receive full treatment the number of acutely ill patients is growing significantly. This development a major challenge to current concepts of intensive care and it needs to be redefined who of these patients should be treated, for how long and how intensively.

To demonstrate a Web-based electronic peer review system that has the potential to improve quality of care for radiation therapy patients. The system provides tools that allow radiation oncologists to seek peer review of target and critical structure delineation, treatment plans, and share clinical data with peers to optimize radiation therapy treatments. Peer review of radiation therapy treatment planning data prior to its initiation improves the quality of radiation therapy and clinical outcomes. Web-based access to radiation therapy treatment planning data and medical records mitigate existing geographical and temporal constraints. With internet access, the healthcare provider can access the data from any location and review it in an interactive and collaborative manner. Interoperability standard like DICOM-RT and IHE-RO compliant RT Systems have facilitated the design and implementation of PRS with Silverlight Web technology, .net Framework and SQL Server. Local DICOM-RT archive and cloud based services are deployed to facilitate remote peer reviews. To validate the PRS system, we tested the system for 100 patients with Philips Pinnacle v 9.0 and Varian Eclipse v 8.9 treatment planning system (TPS). We transmitted the DICOM RT data from the TPS to the cloud based services via the PRS local DICOM RT Archive. Various CT simulation based parameters such as orientation of CT, properties of RT structures etc. were compared between the TPS and PRS system. Data integrity of other parameters such as patient demographics (patient name, ID, attending physician etc.) and dose volume related parameters were also evaluated. Such rigorous testing allowed us to optimize the functionalities and clinical implementation of the PRS. We believe that the PRS will improve the quality and safety of a broad spectrum of radiation therapy patients treated in underserved areas while discouraging the overutilization of expensive radiation treatment modalities.

Chemotherapy prolongs survival in patients with advanced non-small-cell lung cancer. However, few studies have included patients with poor performance status. This study examined rates of oncologists' recommendations for chemotherapy by patient performance status and symptoms and how physician characteristics influence chemotherapy recommendations. We surveyed medical oncologists involved in the care of a population-based cohort of patients with lung cancer from the CanCORS (Cancer Care Outcomes Research and Surveillance) study. Physicians were queried about their likelihood to recommend chemotherapy to patients with stage IV lung cancer with varying performance status (Eastern Cooperative Oncology Group performance status 0 [good] v 3 [poor]) and presence or absence of tumor-related pain. Repeated measures logistic regression was used to estimate the independent associations of patients' performance status and symptoms and physicians' demographic and practice characteristics with chemotherapy recommendations. Nearly all physicians (adjusted rate, 97% to 99%) recommended chemotherapy for patients with good performance status, and approximately half (adjusted rate, 38% to 53%) recommended chemotherapy for patients with poor performance status (P < .001). Compared with patient factors, physician and practice characteristics were less strongly associated with chemotherapy recommendations in adjusted analyses. Strong consensus among oncologists exists for chemotherapy in patients with advanced non-small-cell lung cancer and good performance status. However, the relatively high rate of chemotherapy recommendations for patients with poor performance status despite the unfavorable risk-benefit profile highlights the need for ongoing work to define high-value care in oncology and to implement and evaluate strategies to align incentives for such care.

To evaluate the career plans, professional expectations, and well-being of oncology fellows compared with actual experiences of practicing oncologists. US oncology fellows taking the 2013 Medical Oncology In-Training Examination (MedOnc ITE) were invited to participate in an optional postexamination survey. The survey evaluated fellows’ career plans and professional expectations and measured burnout, quality of life (QOL), fatigue, and satisfaction with work-life balance (WLB) using standardized instruments. Fellows’ professional expectations and well-being were compared with actual experiences of US oncologists assessed simultaneously. Of the 1,637 oncology fellows in the United States, 1,373 (83.9%) took the 2013 MedOnc ITE. Among these, 1,345 (97.9%) completed the postexamination survey. The frequency of burnout among fellows decreased from 43.3% in year 1 to 31.7% in year 2 and 28.1% in year 3 (P < .001). Overall, the rate of burnout among fellows and practicing oncologists was similar (34.1% v. 33.7%; P = .86). With respect to other dimensions of well-being, practicing oncologists had lower fatigue (P < .001) and better overall QOL scores (P < .001) than fellows but were less satisfied with WLB (P = .0031) and specialty choice (P < .001). Fellows’ expectations regarding future work hours were 5 to 6 hours per week fewer than oncologists’ actual reported work hours. Levels of burnout (P = .02) and educational debt (P < or =.004) were inversely associated with ITE scores. Fellows with greater educational debt were more likely to pursue private practice and less likely to plan an academic career. Oncology fellows entering practice trade one set of challenges for another. Unrealized expectations regarding work hours may contribute to future professional dissatisfaction, burnout, and challenges with WLB.

The prevalence and causes of 'burnout' and psychiatric disorder among senior oncologists and palliative care specialists have been measured in a national questionnaire-based survey. All consultant non-surgical oncologists in the UK were asked to participate. Sources of work-related stress and satisfaction were measured using study-specific questions which were aggregated into factors. Psychiatric disorder was estimated using the 12-item General Health Questionnaire. The three components of 'burnout'--emotional exhaustion, depersonalisation and low personal accomplishment--were assessed using the Maslach Burnout Inventory. Three hundred and ninety-three out of 476 (83%) consultants returned their questionnaires. The estimated prevalence of psychiatric disorder in cancer clinicians was 28%, and this is similar to the rate among British junior house officers. The study group had equivalent levels of emotional exhaustion and low personal accomplishment to those found in American doctors and nurses, but lower levels of depersonalisation. Among cancer clinicians, 'burnout' was more prevalent among clinical oncologists than among medical oncologists and palliative care specialists. Psychiatric disorder was independently associated with the stress of feeling overloaded (P < 0.0001), dealing with treatment toxicity/errors (P < 0.004) and deriving little satisfaction from professional status/esteem (P = 0.002). 'Burnout' was also related to these factors, and in addition was associated with high stress and low satisfaction from dealing with patients, and with low satisfaction from having adequate resources (each at a level of P < or = 0.002). Clinicians who felt insufficiently trained in communication and management skills had significantly higher levels of distress than those who felt sufficiently trained. If 'burnout' and psychiatric disorder among cancer clinicians are to be reduced, increased resources will be required to lessen overload and to improve training in communication and management skills.

After purchase of radiotherapy equipment in 2003, classic radiation therapy in Serbia will reach the highest world level. In order to define the highest standards in radiation technology, we analyzed the current status and potential perspectives of radiation therapy. An analysis of present situation in the USA, assumed as the most developed in the world, was done. Available data, collected in the last 3 years (equipment assortment, therapy modalities, workload and manpower) for 284 radiotherapy centers, out of potential 2050, were analyzed. Results were presented as crude percentage and matched to point current status. The analysis showed that CLINAC accelerators are the most popular (82.7%), as well as, ADAC (43.7%) and Focus (CMS) (27.4%) systems for therapy planning. Movement towards virtual simulation is evident (59.3%), although classic "simulation" is not fully eliminated from the radiotherapy chain. The most popular brachytherapy afterloader is Microselectron HDR (71%). About 64.4% centers use IMPAC communication/verification/record system that seems more open than Varis. All centers practice modern radiotherapy modalities and techniques (CPRT, IMRT, SRS/SRT, TBI, IORT, IVBHRT, HDR BHRT, etc.). CT and MRI availability is out of question, but PET is available in 3% of centers, however this percentage is rapidly growing. Up to 350 new patients per year are treated by one accelerator (about 35 pts. a day). Centers are relatively small and utilize 2-3 accelerators on average. Average FTE staffing norm is 4 radiation oncologists, 2-3 medical radiotherapy physicists, about 3 certified medical dosimetrists and about 6 radiotherapy technologists. In the past 5 years relative stagnation in classic radiotherapy has been observed. In spite of substantial investments in technology and consequent improvements, as well as wide introduction of computers in radiotherapy, radiotherapy results have not changed significantly. Vendor developement strategies do not point that this trend will change in the next 5 years. On the other hand, wide introduction of the PET in each radiotherapy chain ring (diagnostics, planning, follow-up), could improve results (local and regional control, as well as quality of patients' life).

Anaesthetic perioperative management of patients with pancreatic cancer

Pancreatic cancer remains a significant and unresolved therapeutic challenge. Currently, the only curative treatment for pancreatic cancer is surgical resection. Pancreatic surgery represents a technically demanding major abdominal procedure that can occasionally lead to a number of pathophysiological alterations resulting in increased morbidity and mortality. Systemic, rather than surgical complications, cause the majority of deaths. Because patients are increasingly referred to surgery with at advanced ages and because pancreatic surgery is extremely complex, anaesthesiologists and surgeons play a crucial role in preoperative evaluations and diagnoses for surgical intervention. The anaesthetist plays a key role in perioperative management and can significantly influence patient outcome. To optimise overall care, patients should be appropriately referred to tertiary centres, where multidisciplinary teams (surgical, medical, radiation oncologists, gastroenterologists, interventional radiologists and anaesthetists) work together and where close cooperation between surgeons and anaesthesiologists promotes the safe performance of major gastrointestinal surgeries with acceptable morbidity and mortality rates. In this review, we sought to provide simple daily recommendations to the clinicians who manage pancreatic surgery patients to make their work easier and suggest a joint approach between surgeons and anaesthesiologists in daily decision making.

Relilgious beliefs and practices of Taiwanese parents of pediatric patients with cancer.

The aim of this study was to increase understanding of religious beliefs and practices among Taiwanese parents of pediatric patients. Parents of 63 pediatric patients with cancer were interviewed to explore their related religious beliefs and practices, ie, worship at temple, drawing Chien, and divinations. Rituals were used to diminish the harmful effects of the child's disease, such as temple ceremonies, changing the child's name, and taking "Fu" water. Such practices were generally undertaken with a lack of medical guidance from oncologists largely because of poor interactions between parents and oncologists. The findings suggest that discovering a caregiver's worldview and cultural values is important to establish holistic nursing practices. Because immigrants increasingly move around the world, Taiwanese parents become a culturally diverse clientele for healthcare professionals who have to be aware of the existing cultural differences in healthcare values, patterns, and practices, particularly between Western and Eastern cultures.

Evidence regarding opinions on integrative modalities by patients and physicians is lacking. Methods . A survey study was conducted assessing how integrative modalities were valued among hematology/oncology patients and hematologists and oncologists at a major tertiary medical center. Results. 1008 patients and 55 physicians were surveyed. With the exception of support groups, patients valued nutrition services, exercise therapy, spiritual/religious counseling, supplement/herbal advice, support groups, music therapy, and other complimentary medicine services significantly more than physicians ( P ≤ 0.05). Conclusion . With the exception of support groups, patients value integrative modalities more than physicians. Perhaps with increasing education, awareness, and acceptance by providers and traditional institutions, integrative modalities could be equally valued between patients and providers. It is possible that increased availability and utilization of integrative oncology modalities at tertiary hospital sites could improve patient satisfaction, quality of life, and other clinical endpoints.

Strategies of persuasion in offers to participate in cancer clinical trials I: Topic placement and topic framing.

Clinical trials are the gold standard in medical research evaluating new treatments in cancer care; however, in the United States, too few patients enroll in trials, especially patients from minority groups. Offering patients the option of a clinical trial is an ethically-charged communicative event for oncologists. One particularly vexed ethical issue is the use of persuasion in trial offers. Based on a corpus of 22 oncology encounters with Caucasian-American (n = 11) and African-American (n = 11) patients, this discourse analysis describes oncologists' use of two persuasive strategies related to the linguistic structure of trial offers: topic placement and topic framing. Findings are presented in total and by patient race, and discussed in terms of whether these strategies may constitute ethical or unethical persuasion, particularly with respect to the ethical issue of undue influence and the social issue of underrepresentation of minorities in cancer clinical trials.

Purpose: Accurate delineation of organs at risk (OARs) on computed tomography (CT) image is required for radiation treatment planning (RTP). Manual delineation of OARs being time consuming and prone to high interobserver variability, many (semi-) automatic methods have been proposed. However, most of them are specific to a particular OAR. Here, an interactive computer-assisted system able to segment various OARs required for thoracic radiation therapy is introduced. Methods: Segmentation information (foreground and background seeds) is interactively added by the user in any of the three main orthogonal views of the CT volume and is subsequently propagated within the whole volume.more » The proposed method is based on the combination of watershed transformation and graph-cuts algorithm, which is used as a powerful optimization technique to minimize the energy function. The OARs considered for thoracic radiation therapy are the lungs, spinal cord, trachea, proximal bronchus tree, heart, and esophagus. The method was evaluated on multivendor CT datasets of 30 patients. Two radiation oncologists participated in the study and manual delineations from the original RTP were used as ground truth for evaluation. Results: Delineation of the OARs obtained with the minimally interactive approach was approved to be usable for RTP in nearly 90% of the cases, excluding the esophagus, which segmentation was mostly rejected, thus leading to a gain of time ranging from 50% to 80% in RTP. Considering exclusively accepted cases, overall OARs, a Dice similarity coefficient higher than 0.7 and a Hausdorff distance below 10 mm with respect to the ground truth were achieved. In addition, the interobserver analysis did not highlight any statistically significant difference, at the exception of the segmentation of the heart, in terms of Hausdorff distance and volume difference. Conclusions: An interactive, accurate, fast, and easy-to-use computer-assisted system able to segment various OARs required for thoracic radiation therapy has been presented and clinically evaluated. The introduction of the proposed system in clinical routine may offer valuable new option to radiation oncologists in performing RTP.« less

To examine the nature of the trust that Turkish and Arabic ethnic minority patients suffering from cancer have in their oncologist, and to explore how this trust is established. We interviewed 9 cancer patients with Turkish and Arabic backgrounds about the trust they have in their oncologist. Semi-structured qualitative interviews. We interviewed 9 cancer patients with Turkish and Arabic backgrounds about the trust they have in their oncologist. The trust that these patients have in their oncologist seemed to evolve gradually over time. According to the patients, three specific elements seemed to promote trust. Firstly, patients attached importance to a strongly proactive physician approach, even in the palliative phase when treatment was no longer indicated. A wait-and-see attitude was perceived by patients as a lack of willingness to help, and was detrimental to their trust. Secondly, patients indicated that they needed their oncologist to reassure them and avoided discussing depressing topics, so that they would not give up hope. Finally, the oncologist's non-verbal communication, particularly his or her facial expression, contributed to patients' trust. Among these Turkish and Arabic ethnic minority cancer patients, trust in the physician appeared not to be self-evident, and might to some extent need to be 'earned' by oncologists. Because of these patients' great need for a proactive attitude, it is desirable that oncologists clearly explain their motivation when choosing for a possibly less active approach. In order to preserve hope, it is important that oncologists discover exactly what their patients' information needs are. The results of this explorative, small-scale study may help physicians to optimise the trust that Turkish and Arabic ethnic minority patients have in them.

In this study, we explore the quality aspects of radiation care from the patient's perspective in order to develop a draft Consumer Quality Index (CQI) Radiation Care instrument. Four focus group discussions with (former) cancer patients were held to explore the aspects determining the quality of radiation care. The list of aspects generated was categorised based on similarity and importance in a concept mapping procedure. Four focus group discussions revealed seven main themes related to the quality of radiation care: information provision, a patient-centred approach, professional competence, planning and waiting times, accessibility, cooperation and communication, and follow-up care. Results of concept mapping procedures revealed which items the patients considered to be most important. A radiation oncologist who is up to date about the patient's file is of paramount importance for cancer patients receiving radiotherapy. The quality aspects found through focus group discussions provided useful insight into how patients experience radiation care. Furthermore, concept mapping made these results more solid. To evaluate the quality of radiation care from the patient's perspective, these quality aspects will be guiding in the development of a CQI Radiation Care. Copyright © 2011 Elsevier Ireland Ltd.

Purpose: To develop a high-resolution target volume atlas with intensity-modulated radiotherapy (IMRT) planning guidelines for the conformal treatment of anal cancer. Methods and Materials: A draft contouring atlas and planning guidelines for anal cancer IMRT were prepared at the Australasian Gastrointestinal Trials Group (AGITG) annual meeting in September 2010. An expert panel of radiation oncologists contoured an anal cancer case to generate discussion on recommendations regarding target definition for gross disease, elective nodal volumes, and organs at risk (OARs). Clinical target volume (CTV) and planning target volume (PTV) margins, dose fractionation, and other IMRT-specific issues were also addressed. A steeringmore » committee produced the final consensus guidelines. Results: Detailed contouring and planning guidelines and a high-resolution atlas are provided. Gross tumor and elective target volumes are described and pictorially depicted. All elective regions should be routinely contoured for all disease stages, with the possible exception of the inguinal and high pelvic nodes for select, early-stage T1N0. A 20-mm CTV margin for the primary, 10- to 20-mm CTV margin for involved nodes and a 7-mm CTV margin for the elective pelvic nodal groups are recommended, while respecting anatomical boundaries. A 5- to 10-mm PTV margin is suggested. When using a simultaneous integrated boost technique, a dose of 54 Gy in 30 fractions to gross disease and 45 Gy to elective nodes with chemotherapy is appropriate. Guidelines are provided for OAR delineation. Conclusion: These consensus planning guidelines and high-resolution atlas complement the existing Radiation Therapy Oncology Group (RTOG) elective nodal ano-rectal atlas and provide additional anatomic, clinical, and technical instructions to guide radiation oncologists in the planning and delivery of IMRT for anal cancer.« less

In 2003 ESTRO began a project whose primary objective, was to make a map in the European area of infrastructures in technology and personnel for brachytherapy. A survey and a web site were elaborated. The survey was sent to the 76 Spanish Radiation Oncology departments in May 2003. By the end of 2003, 66 (86.8%) services had responded, 40 (71.4%) of which had brachytherapy. The services with brachytherapy treated 73.5% of the total patients, an average of 1,199 patients. The mean number of patients treated with brachytherapy by department was 135.5 and the number of applications was 265 annually. The average number of specialists was 7, 4 of them trained in brachytherapy. The average weekly work load of the radiation oncologists, physicists, and technicians was 22.6 h, 13.8 h and 21.0 h, respectively. The mean time dedicated to each patient by radiation oncologists, physicists and technicians was 9.2 h; 6.19 h; 7.2 h, respectively. The total number of afterloaders was 43 (22 HDR, 18 LDR, 3 PDR). The tumours most frequently treated with brachytherapy were gynaecological (56.24%), breast (14.2%) and prostate (11.7%). High dose rate was used in 47.46% of the patients and low dose rate in 47.24%. Between 1997 and 2002 there was an increase of 50.53% in patients treated with brachytherapy. The survey shows the brachytherapy resources and activity in Spain up to 2003. Increased use of brachytherapy in prostate tumours, prevalence of gynaecology brachytherapy and similar number of treatments with HDR and LDR are demonstrated in the Patterns of Care of Brachytherapy in Europe (PCBE) study in Spain.

The management of benign and malignant neoplasms of the salivary glands requires precise knowledge of tumor histogenesis and classification as well as surgical skills. Pleomorphic adenoma and Whartin's tumor are the most frequent tumors in parotid glands while the probability for malignant tumors is higher in other glands, especially in sublingual and minor salivary glands. Those malignant salivary glands tumors are rare and necessitate multidisciplinar staging and management in close collaboration with the pathologist and the radiation oncologist.

Quantitative vs. subjective portal verification using digital portal images.

Off-line, computer-aided prescription (simulator) and treatment (portal) image registration using chamfer matching has been implemented on PC based viewing station. The purposes of this study were (a) to evaluate the performance of interactive anatomy and field edge extraction and subsequent registration, and (b) to compare observer's perceptions of field accuracy with measured discrepancies following anatomical registration. Prescription-treatment image pairs for 48 different patients were examined in this study. Digital prescription images were produced with the aid of a television camera and a digital frame grabber, while the treatment images were obtained directly from an on-line portal imaging system. To facilitate perception of low contrast anatomical detail, on-line portal images were enhanced with selective adaptive histogram equalization prior to extraction of anatomical edges. Following interactive extraction of anatomical and field border information by an experienced observer, the identified anatomy was registered using chamfer matching. The degree of conformity between the prescription and treatment fields was quantified using several parameters, which included relative prescription field coverage and overcoverage, as well as the translational and rotational displacements as measured by chamfer matching applied to the boundaries of the two fields. These quantitative measures were compared with subjective evaluations made by four radiation oncologists. All the images in this series that included a range of the most commonly seen treatment sites were registered and the conformity parameters were found. The mean treatment/prescription field coverage and overcoverage were approximately 95 and 7%, respectively before registration. The mean translational displacement in the transverse and cranio-caudal directions were 2.9 and 3.4 mm, respectively. The mean rotational displacement was approximately 2 degrees. For all four oncologists, the portals classified as unacceptable, in terms of the field placement, exhibited significantly higher (p < 0.03) translational errors in the transverse direction. The field coverages were significantly lower (p < 0.05) and the translational errors in the cranio-caudal direction were significantly higher (p < 0.05) for the portals rated as unacceptable by two of the oncologists. From the parameters that were used to quantify the degree of conformity between the prescription and treatment fields, the translational error in the transverse direction correlated best with the oncologists' assessments on the field placement. Field coverage and translational error in the cranio-caudal direction correlated well with assessments of only two out of the four participating oncologists. This can be explained by the fact that for the majority of treatment sites included in the study the positioning of field borders was more critical for the transverse direction. A conclusion for the design of future quantitative and automated on-line portal verification systems is that they will have to model different perceived significances of different types of localization errors intrinsic to oncologist evaluation of portal images.

Three randomized clinical trials have established brachytherapy (BT) boost in combination with external beam radiation therapy (EBRT) and androgen deprivation therapy (ADT) as superior to definitive EBRT and ADT alone in terms of biochemical control (but not overall survival) at the expense of increased toxicity in men with high-risk (HR) prostate cancer (PCa). The current view regarding these 2 treatment algorithms among North American genitourinary (GU) experts is not known. A survey was distributed to 88 practicing North American GU physicians serving on decision-making committees of cooperative group research organizations. Questions pertained to opinions regarding BT as monotherapy for low-risk PCa and BT boost for HR PCa. Responders were asked to self-identify as BT experts versus non-experts. Treatment recommendations were correlated with practice patterns using the Fisher exact test. Forty-two radiation oncologists completed the survey, of whom 23 (55%) recommend EBRT and ADT alone and 19 (45%) recommend addition of BT boost. Twenty-five participants (60%) identified themselves as BT experts. Nearly 90% of those recommending BT boost were BT experts versus approximately 10% of non-BT experts (P < .001). Responders who recommended BT monotherapy as first-choice treatment for low-risk PCa were more likely to recommend BT boost for HR PCa (P < .0001). There is a dramatic polarization in opinions regarding incorporation of BT boost into EBRT + ADT therapy for patients with HR PCa among North American GU radiation oncology experts, who serve on decision-making committees and influence the national treatment guidelines and future clinical trials. Those who identify themselves as BT experts are significantly more likely to recommend BT boost. These findings are likely to influence the national guidelines and implementation of BT boost in current and future North American PCa clinical studies. Copyright © 2018 Elsevier Inc.

We evaluated the feasibility of planning stereotactic body radiotherapy (SBRT) for large central early-stage non-small cell lung cancer with a tri-cobalt-60 (tri-(60)Co) system equipped with real-time magnetic resonance imaging (MRI) guidance, as compared to linear accelerator (LINAC)-based SBRT. In all, 20 patients with large central early-stage non-small cell lung cancer who were treated between 2010 and 2015 with LINAC-based SBRT were replanned using a tri-(60)Co system for a prescription dose of 50Gy in 4 fractions. Doses to organs at risk were evaluated based on established MD Anderson constraints for central lung SBRT. R100 values were calculated as the total tissue volume receiving 100% of the dose (V100) divided by the planning target volume and compared to assess dose conformity. Dosimetric comparisons between LINAC-based and tri-(60)Co SBRT plans were performed using Student׳s t-test and Wilcoxon Ranks test. Blinded reviews by radiation oncologists were performed to assess the suitability of both plans for clinical delivery. The mean planning target volume was 48.3cc (range: 12.1 to 139.4cc). Of the tri-(60)Co SBRT plans, a mean 97.4% of dosimetric parameters per patient met MD Anderson dose constraints, whereas a mean 98.8% of dosimetric parameters per patient were met with LINAC-based SBRT planning (p = 0.056). R100 values were similar between both plans (1.20 vs 1.21, p = 0.79). Upon blinded review by 4 radiation oncologists, an average of 90% of the tri-(60)Co SBRT plans were considered acceptable for clinical delivery compared with 100% of the corresponding LINAC-based SBRT plans (p = 0.17). SBRT planning using the tri-(60)Co system with built-in MRI is feasible and achieves clinically acceptable plans for most central lung patients, with similar target dose conformity and organ at risk dosimetry. The added benefit of real-time MRI-guided therapy may further optimize tumor targeting while improving normal tissue sparing, which warrants further investigation in a prospective feasibility clinical trial.

Background Information in oncological consultations is often excessive. Those patients who better recall information are more satisfied, less anxious and more adherent. Optimal recall may be enhanced by the oncologist's non-verbal communication. We tested the influence of three non-verbal behaviors, i.e. eye contact, body posture and smiling, on patients' recall of information and perceived friendliness of the oncologist. Moreover, the influence of patient characteristics on recall was examined, both directly or as a moderator of non-verbal communication. Material and methods Non-verbal communication of an oncologist was experimentally varied using video vignettes. In total 194 breast cancer patients/survivors and healthy women participated as 'analog patients', viewing a randomly selected video version while imagining themselves in the role of the patient. Directly after viewing, they evaluated the oncologist. From 24 to 48 hours later, participants' passive recall, i.e. recognition, and free recall of information provided by the oncologist were assessed. Results Participants' recognition was higher if the oncologist maintained more consistent eye contact (β = 0.17). More eye contact and smiling led to a perception of the oncologist as more friendly. Body posture and smiling did not significantly influence recall. Older age predicted significantly worse recognition (β = -0.28) and free recall (β = -0.34) of information. Conclusion Oncologists may be able to facilitate their patients' recall functioning through consistent eye contact. This seems particularly relevant for older patients, whose recall is significantly worse. These findings can be used in training, focused on how to maintain eye contact while managing computer tasks.

Summary Background Disagreements between cancer patients and their caregivers about treatment and care can affect the patient’s physical and mental well-being. Therefore it is important to understand if oncologists can accurately identify the presence of patient-caregiver decisional conflict. This study examined assessments made by lung cancer patients, their caregivers, and their oncologists regarding patient-caregiver disagreements concerning treatment and care decisions. Participants and methods We assessed the extent to which the patient, caregiver, and oncologist reported disagreement between the patient and the family member regarding treatment decisions in 134 patient-caregiver-oncologist triads. Descriptive statistics were used to explore rates of concordance amongst all possible combinations of raters. Loglinear models were tested for 3-way agreement. Results Most patient-caregiver pairs, 82.1% (n=110), reported agreement concerning presence or absence of decisional conflict. Oncologists were more successful in detecting absence of conflict than the presence of conflict. When the caregiver and the oncologist agreed, it was regarding the absence of conflict (64.9%), rather than the presence of conflict. In 10.6 % (n = 15) of cases, oncologists reported that conflictual relationships negatively impacted their ability to provide patient care. Conclusions Recent models of cancer patient care promote including the caregiver fully in the process while respecting the primacy of the patient’s perspective. However, these models assume that the oncologist will recognize when disagreements exist and be able to assist in conflict resolution. The degree to which the oncologist identified that conflict exists and implications for their ability to provide patient care when familial disagreements existed are discussed. PMID:22405569

The present study aimed to explore (a) to what extent adolescent cancer survivors express emotional concerns during follow-up consultations, (b) the content of these expressions, and (c) the responses to their concerns by the paediatric haemato-oncologists (oncologists). Sixty-six follow-up consultations between adolescent patients (aged 12-20 years old; mean = 16) and oncologists (n = 10) were video recorded. Emotional concerns were coded using the Verona coding definitions of emotional sequences (VR-CoDES). The content of the concerns was analysed using thematic analysis. Emotional concerns (n = 115) were identified in 50% of the consultations. Of the concerns, 87% were expressed implicitly as hints to the underlying emotion (cues) rather than explicitly (concerns). The oncologists elicited 66.9% of these expressions. Four main categories of emotional concerns were identified in the thematic analysis: physical (31%), psychological (29%), social (17%), and cancer related (23%). The majority (76.5%) of the oncologists' responses to the cues and/or concerns provided space for further disclosure. The oncologists responded less explicitly to the emotional aspects of physical and cancer-related issues in comparison with the cues or concerns of psychological origin. More cues and concerns were expressed when parents were not present in the consultation. In this study, almost half of the adolescent patients presented emotional concerns, and a subgroup presented many concerns; these were mainly expressed when initiated by the oncologists. Oncologists should therefore be attentive to hints to underlying emotions to help the adolescent bring forward his or her concerns. Copyright © 2014 John Wiley & Sons, Ltd.

The aims of this study were to examine the relationship between negative attitudes towards expressing emotion following patient death and burnout in oncologists and to explore oncologists' preferences for institutional interventions to deal with patient death. The participants included a convenience sample of 177 oncologists from Israel and Canada. Oncologists completed a questionnaire package that included a sociodemographic survey, a burnout measure, a survey assessing negative attitudes towards expressing emotion, and a survey assessing desired interventions to cope with patient death. To examine the association between burnout and negative attitudes while controlling for the effect of sociodemographic variables, a hierarchical linear regression was computed. Higher burnout scores were related to higher negative attitudes towards perceived expressed emotion (partial r = .25, p < .01) of those who viewed this affect as a weakness and as a sign of unprofessionalism. Approximately half of the oncologists found each of the five categories of institutional interventions (pedagogical strategies, emotional support, group/peer support, taking time off, and research and training) helpful in coping with patient death. Our findings suggest that high burnout scores are associated with negative attitudes towards expressing emotion and that there is a wide variation in oncologist preferences in coping with patient death. Institutions should promote interventions that are varied and that focus on the needs of oncologists in order to reduce burnout. Interventions that legitimize expression of emotion about patient death may be useful. Another way to reduce stigma would be to require oncologists to "opt out" rather than "opt in" to accessing a selection of social and/or individual interventions.

Cancer in adolescents and young adults in countries with limited resources.

Magrath, Ian; Epelman, Sidnei

Cancer in adolescents and young adults (AYA) represents a higher fraction of all cancer in countries that are still undergoing a demographic transition. Such countries tend to have much younger populations, and therefore unless they have a particularly low incidence of cancer in this age group, will have a higher burden of cancer (absolute number of cases with cancer) in AYA. Cancers in AYA are comprised of the tail end of the incidence curve of cancers that have their peak incidence, or occur almost exclusively in childhood, the beginning of the incidence curve of cancers that primarily affect the elderly, and a third set of cancers that have their peak incidence (or are at least common) in the AYA age group (e.g., testicular cancer, sarcomas, melanoma, thyroid cancer). Many, but not all, of these cancers require radiation or cancer surgery, but the poorest countries do not have a sufficient number of radiation therapy units and surgical oncologists, or indeed medical and pediatric oncologists, to deal with the burden of cancer they face. The AYA age group is particularly important, both with regard to their contribution to the economy now and in the future (the majority are in the "working" age-group defined as 15-64 years), as well as their important role in caring for their families. Moreover, some of these cancers are eminently curable with chemotherapy alone, and more could be cured by simply improving the efficiency of existing health services and providing education and training to both the public as well as oncologists and other specialists required for the care of AYA (although such individuals will not necessarily be exclusively concerned with this age group). Of particular importance is the detection and diagnosis of cancer patients at the earliest possible time in the course of their disease. Avoiding delays in initiating therapy, which are partly due to the poverty and lack of education of the public as well as to a failure on the part of primary health care providers to recognize the possibility of cancer, would lead not only to improved survival and less toxicity, but is likely to reduce the need for radiation as well as the cost of treatment. There are few good quality clinical trials that take place in the LMIC (in relationship to the extent of the existing cancer burden), and research training should be an integral component of capacity building. Research on the efficacy and toxicity of standardized treatment approaches that are either based on principles established in the HIC, or adapted from treatment protocols used in the HIC, would be a good place to begin, but health policy and multisectoral collaboration are essential if improved survival rates are to be achieved. Decisions will also need to be made regarding the treatment of diseases in which radiation or cancer surgery are important elements, when one or both of the latter are unavailable. Late effects are important in this young population in HIC, and protocol adaptations or design in LMIC should take into consideration the significant fraction of cured patients with late effects who were treated in HIC in an era where improving response and survival rates was the paramount consideration-the situation that applies today in less developed countries. Special adolescent units which better deal with psychological issues of young cancer patients are rare in LMIC and the psychosocial issues faced by adolescents are much less studied. Although survival is the first consideration, attention to psychosocial and financial issues may reduce existing delays in initiating therapy and also the fraction of patients that abandon therapy.

Research has demonstrated that communication and care coordination improve cancer patient outcomes. To improve communication and care coordination, it is important to understand primary care providers' (PCPs') perceptions of communication with oncologists as well as PCPs' communication needs. A mixed-methods approach was used in the present study. In the qualitative phase of the study, 18 PCPs practicing in underserved, minority communities were interviewed about their experiences communicating with oncologists. In the quantitative phase of the study, 128 PCPs completed an online survey about their preferences, experiences, and satisfaction with communication with oncologists. Results indicated a PCP-oncologist gap in communication occurred between diagnosis and treatment. PCPs wanted more communication with oncologists, updates on their patients' prognosis throughout treatment, and to be contacted via telephone or email and saw their role as crucial in providing supportive care for their patients. Although PCPs recognize that they play a critical, proactive role in supporting patients throughout the continuum of their cancer care experience, existing norms regarding postreferral engagement and oncologist-PCP communication often hinder activation of this role among PCPs. Expected standards regarding the method, frequency, and quality of postreferral communication should be jointly articulated and made accountable between PCPs and oncologists to help improve cancer patients' quality of care, particularly in minority communities. © 2014 American Cancer Society.

The rising use of complementary and alternative medicine (CAM) means oncologists are increasingly asked by patients to discuss CAM treatment options. However, no formal training or established standards are available on the subject. The aim of this paper was to investigate real-world discussions of CAM treatments. In particular, we wanted to learn about the values, norms and defining features that characterise oncologist-patient discussions on CAM. Semi-standardised interviews with 17 oncologists were analysed using interpretation pattern analysis combined with thematic analysis. Advice on CAM is seen by oncologists as an important service they provide to their patients, even though their knowledge of the subject is often limited. Many interviewees mentioned an apparent lack of scientific proof, especially when their aim was to warn patients against the use of CAM. Discussions on CAM tend to reflect the idea that CAM belongs 'to another world', and judging by the interviews with oncologists, this notion appears to be shared by patients and oncologists alike. Oncologists require reliable information on CAM and would profit from training in the communication of CAM treatment options to patients. Knowing scientific data on CAM would also lower barriers stemming from the view that CAM belongs 'to another world'. Under- and postgraduate education programmes should include training on how to respond to requests addressing possible CAM options.

Optical fibre luminescence sensor for real-time LDR brachytherapy dosimetry

An optical fibre sensor for monitoring low dose radiation is presented. The sensor is based on a scintillation material embedded within the optical fibre core, which emits visible light when exposed to low level ionising radiation. The incident level of ionising radiation can be determined by analysing the optical emission. An optical fibre sensor is developed, based on radioluminescence whereby radiation sensitive scintillation material, terbium doped gadolinium oxysulphide (Gd2O2S:Tb), is embedded in a cavity of 700μm of a 1mm plastic optical fibre. The sensor is designed for in-vivo monitoring of the radiation dose during radio-active seed implantation for low dose rate (LDR) brachytherapy, in prostate cancer treatment, providing radiation oncologists with real-time information of the radiation dose to the target area and/or nearby organs at risk (OARs). The radiation from the brachytherapy seeds causes emission of visible light from the scintillation material through the process of radioluminescence, which penetrates the fibre, propagating along the optical fibre for remote detection using a multi-pixel photon counter. The sensor demonstrates a high sensitivity to 0.397mCi of Iodine125, the radioactive source most commonly used in brachytherapy for treating prostate cancer.

Many cancer deaths are related to metastasis to distant organs due to dissemination of circulating tumor cells (CTCs) shed from the primary tumor. For many years, oncologists believed some medical procedures may provoke metastasis; however, no direct evidence has been reported. We have developed a new, noninvasive technology called in vivo photoacoustic (PA) flow cytometry (PAFC), which provides ultrasensitive detection of CTCs. When CTCs with strongly light-absorbing intrinsic melanin pass through a laser beam aimed at a peripheral blood vessel, laser-induced acoustic waves from CTCs were detected using an ultrasound transducer. We focused on melanoma as it is one of the most metastatically aggressive malignancies. The goal of this research was to determine whether melanoma manipulation, like compression, incisional biopsy, or tumor excision, could enhance penetration of cancer cells from the primary tumor into the circulatory system. The ears of nude mice were inoculated with melanoma cells. Blood vessels were monitored for the presence of CTCs using in vivo PAFC. We discovered some medical procedures, like compression of the tumor, biopsy, and surgery may either initiate CTC release in the blood which previously contained no CTCs, or dramatically increased (10-30-fold) CTC counts above the initial level. Our results warn oncologists to use caution during physical examination, and surgery. A preventive anti-CTC therapy during or immediately after surgery, by intravenous drug administration could serve as an option to treat the resulting release of CTCs.

Immigrants with cancer often have professional and/or family interpreters to overcome challenges communicating with their health team. This study explored the rate and consequences of nonequivalent interpretation in medical oncology consultations. Consecutive immigrant patients with newly diagnosed with incurable cancer, who spoke Arabic, Cantonese, Mandarin, or Greek, were recruited from the practices of 10 medical oncologists in nine hospitals. Their first two consultations were audio taped, transcribed, translated into English and coded. Thirty-two of 78 participants had an interpreter at 49 consultations; 43% of interpreters were family, 35% professional, 18% both a professional and family, and 4% a health professional. Sixty-five percent of professional interpretations were equivalent to the original speech versus 50% for family interpreters (P= .02). Seventy percent of nonequivalent interpretations were inconsequential or positive; however, 10% could result in misunderstanding, in 5% the tone was more authoritarian than originally intended, and in 3% more certainty was conveyed. There were no significant differences in interpreter type for equivalency of interpretations. Nonequivalent interpretation is common, and not always innocuous. Our study suggests that there may remain a role for family or telephone versus face-to-face professional interpreters. careful communication between oncologists and interpreters is required to ensure optimal communication with the patient.

In total, 40-70% of cancer patients use complementary or alternative medicine (CAM). Many of them ask for advice from non-medical practitioners (NMPs). Our aim was to investigate the attitude of NMPs regarding their treatments for cancer patients. A survey was performed on members of NMP associations, using an online questionnaire on diagnosis and treatment, goals for using CAM, communication with the oncologist, and sources of information. Of the 1,500 members of the NMP associations, 299 took part. The treatments were found to be heterogeneous. Homeopathy is used by 45% of the NMPs; 10% believe it to be a treatment directly against cancer. Herbal therapy, vitamins, orthomolecular medicine, ordinal therapy, mistletoe preparations, acupuncture, and cancer diets are used by more than 10% of the NMPs. None of the treatments is discussed with the respective physician on a regular basis. Many therapies provided by NMPs are biologically based and therefore may interfere with conventional cancer therapy. Thus, patients are at risk of interactions, especially as most NMPs do not adjust their therapies to those of the oncologist. Moreover, risks may arise from these CAM methods as NMPs partly believe them to be useful anticancer treatments. This may lead to the delay or even omission of effective therapies. © 2014 S.
