    The purpose of this article is to provide updated recommendations for the treatment of patients with stage IV non–small-cell lung cancer. A literature search identified relevant randomized trials published since 2002. The scope of the guideline was narrowed to chemotherapy and biologic therapy. An Update Committee reviewed the literature and made updated recommendations. One hundred sixty-two publications met the inclusion criteria. Recommendations were based on treatment strategies that improve overall survival. Treatments that improve only progression-free survival prompted scrutiny of toxicity and quality of life. For first-line therapy in patients with performance status of 0 or 1, a platinum-based two-drug combination of cytotoxic drugs is recommended. Nonplatinum cytotoxic doublets are acceptable for patients with contraindications to platinum therapy. For patients with performance status of 2, a single cytotoxic drug is sufficient. Stop first-line cytotoxic chemotherapy at disease progression or after four cycles in patients who are not responding to treatment. Stop two-drug cytotoxic chemotherapy at six cycles even in patients who are responding to therapy. The first-line use of gefitinib may be recommended for patients with known epidermal growth factor receptor (EGFR) mutation; for negative or unknown EGFR mutation status, cytotoxic chemotherapy is preferred. Bevacizumab is recommended with carboplatin-paclitaxel, except for patients with certain clinical characteristics. Cetuximab is recommended with cisplatin-vinorelbine for patients with EGFR-positive tumors by immunohistochemistry. Docetaxel, erlotinib, gefitinib, or pemetrexed is recommended as second-line therapy. Erlotinib is recommended as third-line therapy for patients who have not received prior erlotinib or gefitinib. Data are insufficient to recommend the routine third-line use of cytotoxic drugs. Data are insufficient to recommend routine use of molecular markers to select chemotherapy

    These guidelines, informed by the best available evidence and consensus expert opinion, provide a framework to guide the timely initiation of chemotherapy for treating cancer. They sit at the intersection of patient experience, state-of-the-art disease management and rational efficient service provision for these patients at a system level. Internationally, cancer waiting times are routinely measured and publicly reported. In Australia, there are existing policies and guidelines relating to the timeliness of cancer care for surgery and radiation therapy; however, until now, equivalent guidance for chemotherapy was lacking. Timeliness of care should be informed, where available, by evidence for improved patient outcomes. Independent of this, it should be recognised that shorter waiting periods are likely to reduce patient anxiety. While these guidelines were developed as part of a proposed framework for consideration by the Victorian Department of Health, they are clinically relevant to national and international cancer services. They are intended to be used by clinical and administrative staff within cancer services. Adoption of these guidelines, which are for the timely triage, review and treatment of cancer patients receiving systemic chemotherapy, aims to ensure that patients receive care within a timeframe that will maximise health outcomes, and that access to care is consistent and equitable across cancer services. Local monitoring of performance against this guideline will enable cancer service providers to manage proactively future service demand. PMID:27553996

    Febrile neutropenia (FN) is a severe dose-limiting side effect of myelosuppressive chemotherapy in patients with solid tumors. Clinical practice guidelines recommend primary prophylaxis with G-CSF in patients with an overall ≥ 20 % risk of FN. AIOM Italian guidelines recommend starting G-CSF within 24-72 h after chemotherapy; for daily G-CSF, administration should continue until the absolute neutrophil count (ANC) is 1 × 10(9)/L post-nadir and should not be terminated after ANC increase in the early days of administration. The aim of this study was to assess guideline adherence in oncology practice in Italy. In this multicenter, prospective, observational study, patients were enrolled at the first G-CSF use in any cycle and were followed for two subsequent cycles (or until the end of chemotherapy if less than two additional cycles). Primary objective was to explore G-CSF use in Italian clinical practice; therefore, data were collected on the G-CSF type, timing of administration, and number of doses. 512 eligible patients were enrolled (median age, 62). The most common tumor types were breast (36 %), lung (18 %), and colorectal (13 %). A total of 1,164 G-CSF cycles (daily G-CSF, 718; pegfilgrastim, 446) were observed. Daily G-CSF was administered later than 72 h after chemotherapy in 42 % of cycles, and the median [range] number of doses was four [1, 10]. Pegfilgrastim was administered later than 72 h in 8 % of cycles. G-CSF prophylaxis in Italy is frequently administered in a manner which is not supported by evidence-based guidelines. As this practice may lead to poor outcomes, educational initiatives are recommended. PMID:24307348

    2014-01-01

    Shortages of essential drugs, including critical chemotherapy drugs, have become commonplace. Drug shortages cost significant time and financial resources, lead to adverse patient outcomes, delay clinical trials, and pose significant ethical challenges. Pediatric oncology is particularly susceptible to drug shortages, presenting an opportunity to examine these ethical issues and provide recommendations for preventing and alleviating shortages. We convened the Working Group on Chemotherapy Drug Shortages in Pediatric Oncology (WG) and developed consensus on the core ethical values and practical actions necessary for a coordinated response to the problem of shortages by institutions, agencies, and other stakeholders. The interdisciplinary and multiinstitutional WG included practicing pediatric hematologist-oncologists, nurses, hospital pharmacists, bioethicists, experts in emergency management and public policy, legal scholars, patient/family advocates, and leaders of relevant professional societies and organizations. The WG endorsed 2 core ethical values: maximizing the potential benefits of effective drugs and ensuring equitable access. From these, we developed 6 recommendations: (1) supporting national polices to prevent shortages, (2) optimizing use of drug supplies, (3) giving equal priority to evidence-based uses of drugs whether they occur within or outside clinical trials, (4) developing an improved clearinghouse for sharing drug shortage information, (5) exploring the sharing of drug supplies among institutions, and (6) developing proactive stakeholder engagement strategies to facilitate prevention and management of shortages. Each recommendation includes an ethical rationale, action items, and barriers that must be overcome. Implemented together, they provide a blueprint for effective and ethical management of drug shortages in pediatric oncology and beyond. PMID:24488741

    For clinically node-positive breast cancer patients receiving neoadjuvant chemotherapy, approximately 40 % will be found to be pathologically node negative. The American College of Surgeons Oncology Group Z1071 trial was therefore conducted to evaluate sentinel lymph node dissection (SLND) in these patients. The trial's primary end point was to determine the false-negative rate (FNR) among patients with clinical N1 disease in whom at least 2 sentinel lymph nodes (SLNs) were identified. The FNR was 12.6 %, which exceeded the prespecified end point of 10.0 %. After data publication, our multidisciplinary team discussed the trial results and how we may incorporate the findings into clinical practice. Patient selection and surgical technique are critical. As an example, when dual tracer technique was used, the FNR was 10.8 %. Data from the trial presented at the San Antonio Breast Cancer Symposium suggested that the FNR could be improved if a clip was placed in the biopsy-proven positive lymph node and removal of that node during SLND was confirmed. Taking this into consideration, we have proposed an approach to surgical management of the axilla in clinically node-positive patients receiving neoadjuvant chemotherapy termed targeted axillary dissection (TAD). TAD involves placing a clip at the time a lymph node is determined to be positive. After completion of neoadjuvant chemotherapy, the clipped node is localized by using a wire or radioactive seed, and during the SLND procedure, all SLNs and the clipped node are removed. We are currently evaluating the efficacy of TAD in axillary staging after neoadjuvant chemotherapy. PMID:24841348

    The tissue microarray is a recently-implemented, high-throughput technology for the analysis of molecular markers in oncology. This research tool permits the rapid assessment of a biomarker in thousands of tumor samples, using commonly available laboratory assays such as immunohistochemistry and in-situ hybridization. Although introduced less than a decade ago, the TMA has proven to be invaluable in the study of tumor biology, the development of diagnostic tests, and the investigation of oncological biomarkers. This review describes the impact of TMA-based research in clinical oncology and its potential future applications. Technical aspects of TMA construction, and the advantages and disadvantages inherent to this technology are also discussed. PMID:18314063

    2005-08-01

    The clinical status of terminal cancer patients is very complex and is affected by several severe symptoms, of extended duration, changing with time and of multifactorial origin. When there are no reasonable cancer treatments specifically able to modify the natural history of the disease, symptom control acquires priority and favours the possible better adaptation to the general inexorable deterioration related to the neoplasic progression. Despite the important advances in Palliative Medicine, symptoms are frequently observed that are intolerable for the patient and which do not respond to usual palliative measures. This situation, characterised by rapid deterioration of the patient, very often heralds, implicitly or explicitly, approaching death. The intolerable nature and being refractory to treatment indicates to the health-care team, on many occasions, the need for sedation of the patient. The requirement for sedation of the cancer patient is a situation that does not allow for an attitude of doubt regarding maintenance of the patient in unnecessary suffering for more than a reasonable time. Given the undoubted clinical difficulty in its indication, it is important to have explored at an earlier stage all usual treatments possible and the grade of response, commensurate with the patient's values and desires. Sedation consists of the deliberate administration of drugs in minimum doses and combinations required not only to reduce the consciousness of the patients but also to achieve adequate alleviation of one or more refractory symptoms, and with the prior consent given by the patient explicitly, or implicitly or delegated. Sedation is accepted as ethically warranted when considering the imperative of palliation and its administration and, whenever contemplated, the arguments that justify them are clear recorded in the clinical history. It is not an easy decision for the physician since, traditionally, the training has been "for the fight to save life

    Purpose: To establish benchmark outcomes for combined modality treatment to be used in future prospective studies of osteolymphoma (primary bone lymphoma). Methods and Materials: In 1999, the Trans-Tasman Radiation Oncology Group (TROG) invited the Australasian Leukemia and Lymphoma Group (ALLG) to collaborate on a prospective study of limited chemotherapy and radiotherapy for osteolymphoma. The treatment was designed to maintain efficacy but limit the risk of subsequent pathological fractures. Patient assessment included both functional imaging and isotope bone scanning. Treatment included three cycles of CHOP chemotherapy and radiation to a dose of 45 Gy in 25 fractions using a shrinking field technique. Results: The trial closed because of slow accrual after 33 patients had been entered. Accrual was noted to slow down after Rituximab became readily available in Australia. After a median follow-up of 4.3 years, the five-year overall survival and local control rates are estimated at 90% and 72% respectively. Three patients had fractures at presentation that persisted after treatment, one with recurrent lymphoma. Conclusions: Relatively high rates of survival were achieved but the number of local failures suggests that the dose of radiotherapy should remain higher than it is for other types of lymphoma. Disability after treatment due to pathological fracture was not seen.

    Veterinary clinical oncology involves a multidisciplinary approach to the recognition and management of spontaneously occurring neoplasms of domestic animals. This requires some knowledge of the causes, incidence, and natural course of malignant disease as it occurs in domestic species. The purpose of this course is to acquaint you with the more common neoplastic problems you will encounter in practice, so that you can offer your clients an informed opinion regarding prognosis and possible therapeutic modalities. A major thrust will be directed toward discussing and encouraging treatment/management of malignant disease. Multimodality therapy will be stressed. 10 refs., 3 tabs.

    Context Fatigue is a distressing, persistent sense of physical tiredness that is not proportional to a person’s recent activity. Fatigue impacts patients’ treatment decisions and can limit their self-care activities. While significant interindividual variability in fatigue severity has been noted, little is known about predictors of interindividual variability in initial levels and trajectories of evening fatigue severity in oncology patients receiving chemotherapy (CTX). Objectives To determine whether demographic, clinical, and symptom characteristics were associated with initial levels as well as the trajectories of evening fatigue. Methods A sample of outpatients with breast, gastrointestinal, gynecological, and lung cancer (N=586) completed demographic and symptom questionnaires a total of six times over two cycles of CTX. Fatigue severity was evaluated using the Lee Fatigue Scale. Hierarchical linear modeling (HLM) was used to answer the study objectives. Results A large amount of interindividual variability was found in the evening fatigue trajectories. A piecewise model fit the data best. Patients who were White, diagnosed with breast, gynecological, or lung cancer, and who had more years of education, child care responsibilities, lower functional status, and higher levels of sleep disturbance and depression reported higher levels of evening fatigue at enrollment. Conclusion This study identified both non-modifiable (e.g., ethnicity) and modifiable (e.g., child care responsibilities, depressive symptoms, sleep disturbance) risk factors for more severe evening fatigue. Using this information, clinicians can identify patients at higher risk for more severe evening fatigue, provide individualized patient education, and tailor interventions to address the modifiable risk factors.

    Cancer stem cells (CSCs) are a small, characteristically distinctive subset of tumor cells responsible for tumor initiation and progression. Several treatment modalities, such as surgery, glycolytic inhibition, driving CSC proliferation, immunotherapy, and hypofractionated radiotherapy, may have the potential to eradicate CSCs. We propose that monitoring CSCs is important in clinical oncology as CSC populations may reflect true treatment response and assist with managing treatment strategies, such as defining optimal chemotherapy cycles, permitting pretreatment cancer surveillance, conducting a comprehensive treatment plan, modifying radiation treatment, and deploying rechallenge chemotherapy. Then, we describe methods for monitoring CSCs. PMID:26929644

    Background Readmission within 30 days is a measure of care quality. Ovarian cancer patients are at high risk for readmission, but specific risk factors are not defined. This study was designed to determine risk factors in patients with ovarian cancer receiving upfront surgery and chemotherapy. Methods The study population was enrolled to GOG 0218. Factors predictive of admission within 30 days of a previous admission or 40 days of cytoreductive surgery were investigated. Categorical variables were compared by Pearson chi-square test, continuous variables by Wilcoxon–Mann–Whitney test. A logistic regression model was used to evaluate independent prognostic factors and to estimate covariate-adjusted odds. All tests were two-tailed, α = 0.05. Results Of 1873 patients, 197 (10.5%) were readmitted, with 59 experiencing >1 readmission. One-hundred-forty-four (73%) readmissions were post-operative (readmission rate 7.7%). Significant risk factors include: disease stage (stage 3 vs 4, p = 0.008), suboptimal cytoreduction (36% vs 64%, p = 0.001), ascites, (p = 0.018), BMI (25.4 vs 27.6, p < 0.001), poor PS (p < 0.001), and higher baseline CA 125 (p = 0.017). Patients readmitted within 40 days of surgery had a significantly shorter interval from surgery to chemotherapy initiation (22 versus 32 days, p < 0.0001). Patients treated with bevacizumab had higher readmission rates in the case of patients with >1 readmission. On multivariate analysis, the odds of re-hospitalization increased with doubling of BMI (OR = 1.81, 95% CI: 1.07–3.07) and PS of 2 (OR = 2.05, 95% CI 1.21–3.48). Conclusion Significant risk factors for readmission in ovarian cancer patients undergoing primary surgery and chemotherapy include stage, residual disease, ascites, high BMI and poor PS. Readmissions are most likely after the initial surgical procedure, a discrete period to target with a prospective intervention. PMID:26335594

    The use of clinical pathways in oncology care is increasingly important to patients and oncology providers as a tool for enhancing both quality and value. However, with increasing adoption of pathways into oncology practice, concerns have been raised by ASCO members and other stakeholders. These include the process being used for pathway development, the administrative burdens on oncology practices of reporting on pathway adherence, and understanding the true impact of pathway use on patient health outcomes. To address these concerns, ASCO's Board of Directors established a Task Force on Clinical Pathways, charged with articulating a set of recommendations to improve the development of oncology pathways and processes, allowing the demonstration of pathway concordance in a manner that promotes evidence-based, high-value care respecting input from patients, payers, and providers. These recommendations have been approved and adopted by ASCO's Board of Directors on August 12, 2015, and are presented herein. PMID:26759491

    Purpose To update the American Society of Clinical Oncology (ASCO) guideline for antiemetics in oncology. Methods A systematic review of the medical literature was completed to inform this update. MEDLINE, the Cochrane Collaboration Library, and meeting materials from ASCO and the Multinational Association for Supportive Care in Cancer were all searched. Primary outcomes of interest were complete response and rates of any vomiting or nausea. Results Thirty-seven trials met prespecified inclusion and exclusion criteria for this systematic review. Two systematic reviews from the Cochrane Collaboration were identified; one surveyed the pediatric literature. The other compared the relative efficacy of the 5-hydroxytryptamine-3 (5-HT3) receptor antagonists. Recommendations Combined anthracycline and cyclophosphamide regimens were reclassified as highly emetic. Patients who receive this combination or any highly emetic agents should receive a 5-HT3 receptor antagonist, dexamethasone, and a neurokinin 1 (NK1) receptor antagonist. A large trial validated the equivalency of fosaprepitant, a single-day intravenous formulation, with aprepitant; either therapy is appropriate. Preferential use of palonosetron is recommended for moderate emetic risk regimens, combined with dexamethasone. For low-risk agents, patients can be offered dexamethasone before the first dose of chemotherapy. Patients undergoing high emetic risk radiation therapy should receive a 5-HT3 receptor antagonist before each fraction and for 24 hours after treatment and may receive a 5-day course of dexamethasone during fractions 1 to 5. The Update Committee noted the importance of continued symptom monitoring throughout therapy. Clinicians underestimate the incidence of nausea, which is not as well controlled as emesis.

    A workshop entitled "Lessons Learned from Radiation Oncology Trials" was held on December 7-8, 2011, in Bethesda, MD, to present and discuss some of the recently conducted radiation oncology clinical trials with a focus on those that failed to refute the null hypothesis. The objectives of this workshop were to summarize and examine the questions that these trials provoked, to assess the quality and limitations of the preclinical data that supported the hypotheses underlying these trials, and to consider possible solutions to these challenges for the design of future clinical trials. Several themes emerged from the discussions: (i) opportunities to learn from null-hypothesis trials through tissue and imaging studies; (ii) value of preclinical data supporting the design of combinatorial therapies; (iii) significance of validated biomarkers; (iv) necessity of quality assurance in radiotherapy delivery; (v) conduct of sufficiently powered studies to address the central hypotheses; and (vi) importance of publishing results of the trials regardless of the outcome. The fact that well-designed hypothesis-driven clinical trials produce null or negative results is expected given the limitations of trial design and complexities of cancer biology. It is important to understand the reasons underlying such null results, however, to effectively merge the technologic innovations with the rapidly evolving biology for maximal patient benefit through the design of future clinical trials.

    Positron emission tomography (PET) provides metabolic information that has been documented to be useful in patient care. The properties of positron decay permit accurate imaging of the distribution of positron-emitting radiopharmaceuticals. The wide array of positron-emitting radiopharmaceuticals has been used to characterize multiple physiologic and pathologic states. PET is used for characterizing brain disorders such as Alzheimer disease and epilepsy and cardiac disorders such as coronary artery disease and myocardial viability. The neurologic and cardiac applications of PET are not covered in this review. The major utilization of PET clinically is in oncology and consists of imaging the distribution of fluorine 18 fluorodeoxyglucose (FDG). FDG, an analogue of glucose, accumulates in most tumors in a greater amount than it does in normal tissue. FDG PET is being used in diagnosis and follow-up of several malignancies, and the list of articles supporting its use continues to grow. In this review, the physics and instrumentation aspects of PET are described. Many of the clinical applications in oncology are mature and readily covered by third-party payers. Other applications are being used clinically but have not been as carefully evaluated in the literature, and these applications may not be covered by third-party payers. The developing applications of PET are included in this review. PMID:15044750

    Adaptive designs have become popular in clinical trial and drug development. Unlike traditional trial designs, adaptive designs use accumulating data to modify the ongoing trial without undermining the integrity and validity of the trial. As a result, adaptive designs provide a flexible and effective way to conduct clinical trials. The designs have potential advantages of improving the study power, reducing sample size and total cost, treating more patients with more effective treatments, identifying efficacious drugs for specific subgroups of patients based on their biomarker profiles, and shortening the time for drug development. In this article, we review adaptive designs commonly used in clinical trials and investigate several aspects of the designs, including the dose-finding scheme, interim analysis, adaptive randomization, biomarker-guided randomization, and seamless designs. For illustration, we provide examples of real trials conducted with adaptive designs. We also discuss practical issues from the perspective of using adaptive designs in oncology trials.

    Patient-reported outcome (PRO) questionnaires assess topics a patient can report about his or her own health. This includes symptoms (eg, nausea, fatigue, diarrhea, pain, or frequent urination), physical functioning (eg, difficulty climbing stairs or difficulty fastening buttons), and mental health (eg, anxiety, fear, or worry). Electronic PRO (ePRO) systems are used in oncology clinical care because of 1) their ability to enhance clinical care by flagging important symptoms and saving clinicians time; 2) the availability of standardized methods for creating and implementing PROs in clinics; and 3) the existence of user-friendly platforms for patient self-reporting like tablet computers and automated telephone surveys. Many ePRO systems can provide actionable links to clinical care such as summary reports in a patient's electronic medical record and real-time e-mail alerts to providers when patients report acute needs. This review presents 5 examples of ePRO systems currently in use in oncology practice. These systems support multiple clinical activities, including assessment of symptoms and toxicities related to chemotherapy and radiation, postoperative surveillance, and symptom management during palliative care and hospice. Patient self-reporting is possible both at clinical visits and between visits over the Internet or by telephone. The implementation of an ePRO system requires significant resources and expertise, as well as user training. ePRO systems enable regular monitoring of patient symptoms, function, and needs, and can enhance the efficiency and quality of care as well as communication with patients.

    The role of chemotherapy in malignant neuroendocrine tumours is difficult to assess because of their rarity and variation in biological behaviour. We present a retrospective review of chemotherapy given to 18 patients with metastatic and one with locally advanced neuroendocrine tumours. There were eight poorly differentiated neuroendocrine tumours, six thyroid medullary carcinomas, two phaeochromocytomas, two pancreatic islet cell tumours and one undifferentiated neuroblastoma. Four patients were given 3-weekly dacarbazine, vincristine and cyclophosphamide (DOC) chemotherapy. In eight patients, this regimen was modified by substituting the dacarbazine and cisplatin and etoposide (OPEC). A further six patients were treated with dacarbazine reintroduced into the 3-weekly regimen (DOPEC). The remaining patient received cisplatin and etoposide. There were two complete responses (both with OPEC) and eight partial responses (two with DOC, three with OPEC and three with DOPEC). Five patients had stable disease and four progressed. Four received further chemotherapy on relapse, producing one complete and one partial response. The median response duration to initial chemotherapy was 10 months (range 3-34). The median survival was 12 months (range 1-42). The main toxicity was haematological, with grade 3-4 neutropenia in 12 patients; eight suffered episodes of sepsis. One death was treatment related. Other toxicity was mild although three patients discontinued vincristine with grade 2 neurotoxicity. The response rate and side effects of these three regimens appear comparable. We conclude that, although these patient numbers are small, combination chemotherapy produces an encouraging response rate (53%; 95% CI 30-75) in malignant neuroendocrine tumours, with acceptable toxicity.

    The essential trace element selenium, which is a crucial cofactor in the most important endogenous antioxidative systems of the human body, is attracting more and more the attention of both laypersons and expert groups. The interest of oncologists mainly focuses in the following clinical aspects: radioprotection of normal tissues, radiosensitizing in malignant tumors, antiedematous effect, prognostic impact of selenium, and effects in primary and secondary cancer prevention. Selenium is a constituent of the small group of selenocysteine-containing selenoproteins and elicits important structural and enzymatic functions. Selenium deficiency has been linked to increased infection risk and adverse mood states. It has been shown to possess cancer-preventive and cytoprotective activities in both animal models and humans. It is well established that Se has a key role in redox regulation and antioxidant function, and hence in membrane integrity, energy metabolism and protection against DNA damage. Recent clinical trials have shown the importance of selenium in clinical oncology. Our own clinical study involving 48 patients suggest that selenium has a positive effect on radiation-associated secondary lymphedema in patients with limb edemas, as well as in the head and neck region, including endolaryngeal edema. Another randomized phase III study of our group was performed to examine the cytoprotective properties of selenium in radiation oncology. The aim was to evaluate whether sodium selenite is able to compensate a preexisting selenium deficiency and to prevent radiation induced diarrhea in adjuvant radiotherapy for pelvic gynecologic malignancies. Through this study, the significant benefits of sodium selenite supplementation with regards to selenium deficiency and radiotherapy induced diarrhea in patients with cervical and uterine cancer has been shown for the first time in a prospective randomized trial. Survival data imply that supplementation with selenium does not

    Evidence has suggested that diabetes may contribute to the initiation and progression of specific types of cancer. Metformin, a biguanide, has become the preferred first-line therapy for the treatment of type 2 diabetes. Metformin is inexpensive, has a proven safety profile and is able to be safely combined with additional antidiabetic agents. In addition to the well-established antidiabetic effects of metformin, there has also been notable interest in its antitumor properties. The present review discusses the emerging role of metformin as an example of an existing drug, used worldwide in the treatment of diabetes, which has been demonstrated to exert significant in vitro and in vivo anticancer activities and has thus been investigated in clinical trials. In gynecologic oncology, metformin has been suggested to exhibit significant treatment efficacy against endometrial cancer. Three studies have demonstrated the potential therapeutic effects of metformin on the survival outcome of patients with ovarian cancer and in ovarian cancer prevention. However, this evidence was based on observational studies. Metformin has been shown to exert no statistically significant beneficial effect on cervical cancer incidence or mortality. By cancer site, the current limited insights highlight the need for clinical investigations and better-designed studies, along with evaluation of the effects of metformin on cancer at other sites.

    Aim: To study the oral health status of Chinese children and adolescents undergoing chemotherapy in Hong Kong. Method: All Chinese children and adolescent oncology patients aged 18 or below attending the Children's Centre for Cancer and Blood Disease at a hospital for chemotherapy were invited and parental consent was sought before they were accepted into the study. The study comprised of 1) a parental questionnaire, 2) the collection of medical history and 3) a clinical examination for tooth decay (caries) and mucosal status. Results: A total of 69 patients were invited, and they all participated in this study. Their mean age was 9.2±5.0 and 44 (64%) were males. Twenty-six patients (38%) had no caries experience (DMFT and/or dmft = 0). Higher caries experience was detected in participants that were not born in Hong Kong, had completed active chemotherapy, participated in school dental care service and whose parents had low educational levels. There were 41 patients with active chemotherapy, 24 of whom were diagnosed with acute leukaemia, 5 with haematological malignancies other than leukaemia and 11 with solid tumours. Antimetabolites, cytotoxic antibiotics, alkylating agents and plant alkaloids were administered in 49%, 32%, 24% and 22% of them, respectively. Twenty-six (63%) patients showed no mucosal complications. The most common oral complication was oral mucositis (24%) followed by petechiae (10%). Conclusion: About two-thirds of paediatric and adolescent cancer patients had caries experience, which was more common among those who had completed chemotherapy. Oral mucositis followed by petechiae were the two most common complications of receiving chemotherapy. PMID:25674168

    Cancer survival continues to improve, and thus cardiovascular consequences of chemotherapy are increasingly important determinants of long-term morbidity and mortality. Conventional strategies to protect the heart from chemotherapy have important hemodynamic or myelosuppressive side effects. Remote ischemic conditioning (RIC) using intermittent limb ischemia-reperfusion reduces myocardial injury in the setting of percutaneous coronary intervention. Anthracycline cardiotoxicity and ischemia-reperfusion injury share common biochemical pathways in cardiomyocytes. The potential for RIC as a novel treatment to reduce subclinical myocyte injury in chemotherapy has never been explored and will be investigated in the Effect of Remote Ischaemic Conditioning in Oncology (ERIC-ONC) trial (clinicaltrials.gov NCT 02471885). The ERIC-ONC trial is a single-center, blinded, randomized, sham-controlled study. We aim to recruit 128 adult oncology patients undergoing anthracycline-based chemotherapy treatment, randomized in a 1:1 ratio into 2 groups: (1) sham procedure or (2) RIC, comprising 4, 5-minute cycles of upper arm blood pressure cuff inflations and deflations, immediately before each cycle of chemotherapy. The primary outcome measure, defining cardiac injury, will be high-sensitivity troponin-T over 6 cycles of chemotherapy and 12 months follow-up. Secondary outcome measures will include clinical, electrical, structural, and biochemical endpoints comprising major adverse cardiovascular clinical events, incidence of cardiac arrhythmia over 14 days at cycle 5/6, echocardiographic ventricular function, N-terminal pro-brain natriuretic peptide levels at 3 months follow-up, and changes in mitochondrial DNA, micro-RNA, and proteomics after chemotherapy. The ERIC-ONC trial will determine the efficacy of RIC as a novel, noninvasive, nonpharmacological, low-cost cardioprotectant in cancer patients undergoing anthracycline-based chemotherapy.

Conventional strategies to protect the heart from chemotherapy have important hemodynamic or myelosuppressive side effects.

    Recent advances in nanotechnology and nanobiotechnology have contributed to the development of nanomaterials, able to be used as drug carriers, probes, targets or cytostatic drugs by itself. Nanomedicine is now the leading area in nanotechnology where a large number and types of nanoparticles (NPs) has been developed and several are already in the clinical practice. Chemotherapy is one of the most widely used strategies to treat cancer. Most chemotherapeutic agents have poor solubility, low bioavailability, and are formulated with toxic solvents. NPs have been designed to overcome the lack of specificity of chemotherapeutic agents as well to improve circulation time in blood, taking advantages on tumor cells characteristics. In immunology, recent advances regarding the activation of the innate immune system artificially enhanced by NPs functionalized with immune-stimulators open a new window as novel methods in vaccines. Also, viruses and virus-like particles (VLPs) engineered to stimulate immune response against their similar virus or as molecular platforms for the presentation of foreign epitopes have been described. In this review we focused in the use of different types of NPs in oncology and immunology, pinpointing the main novelties regarding their development and use of nanotechnology in a broad array of applications, ranging from tumor diagnostics, immune-modulation up to cancer therapeutics.

    Based on the findings of modern molecular biology, breast cancer is nowadays considered to be a heterogeneous disease. This leads to the objective of an individualised, more patient-oriented therapy. A series of target molecules for this purpose has already been identified. The principle of targeted oncological therapy was realised decades ago with the introduction of endocrine therapy for patients with hormone receptor-positive tumours. The modern therapy for HER2-positive tumours is a further example for the translation of targeted therapy into clinical routine. For patients with HER2-negative metastatic breast cancer, to date two targeted drugs, bevacizumab and everolimus, are available for routine clinical use. Many other substances are still undergoing clinical development. However, validated predictive markers to aid in therapeutic decision-making and therapy control are still lacking. Chemotherapy constitutes an effective palliative therapy with proven efficacy for the patients. In this process strategies have also been realised for a targeted therapy against tumour cells with the help of chemotherapeutic agents such as, for example, the intracellular activation of the prodrug capecitabine or the active albumin-mediated transport of nab-paclitaxel which leads to higher peri- and intratumoural enrichments. The continuing unchanged relevance of chemotherapy is often underestimated in the current discussions and will be comprehensively evaluated in this review. PMID:26166838

    The rapid pace of discoveries in tumor biology, imaging technology, and human genetics hold promise for an era of personalized oncology care. The successful development of a handful of new targeted agents has generated much hope and hype about the delivery of safer and more effective new treatments for cancer. The design and conduct of clinical trials has not yet adjusted to a new era of personalized oncology and so we are more in transition to that era than in it. With the development of treatments for breast cancer as a model, we review the approaches to clinical trials and development of novel therapeutics in the prior era of population oncology, the current transitional era, and the future era of personalized oncology.

    Background/Aims To prospectively evaluate our palliative management of unresectable cholangiocarcinoma (CC) treated with tailored multimodal oncological therapy. Methods Between January 2005 and January 2010, 50 consecutive patients with unresectable CC and jaundice were palliated with percutaneous drainage. Forty-three patients underwent metallic-stent implantation followed by brachytherapy. Patients were divided into two arms: the intra-arterial chemotherapy arm (IA arm, n=17) consisted of patients treated with locoregional treatment (IA admission of Cisplatin and 5-fluorouracil, or chemoembolization with Lipiodol) and/or systemic chemotherapy, while the systemic chemotherapy arm (IV arm, n=23) included all the other patients, who were treated only with systemic chemotherapy. Results In total, 78 metal self-expandable stents were placed. Hilar involvement with mass-forming and periductal infiltrating types of CC (84%) was predominant. The average number of percutaneous interventional procedures was 11.61 per patient (range, 4-35). The median overall survival from diagnosis of disease for all patients was 13.5 months (range, 11.0-18.8 months). The median overall survival times were 25.2 months (range, 15.2-31.3 months) and 11.5 months (range, 8.5-12.6 months) in the IA and IV arms, respectively (p<0.05). The 1-, 2-, and 3-year survival rates in the IA and IV arms were 88.2%, 52.9%, and 10.1% and 43.5%, 25.4, and 0%, respectively. There were no major complications (WHO III/IV) due to interventional procedures. Conclusions We could reach acceptable prognosis in patients with unresectable CC using complex tailored oncological therapy. However, the main limitations of prolonging survival are performance status, patient compliance and the maintaining of biliary tract patency. PMID:21103300

    Significant changes in Medicare reimbursement for outpatient oncology services were proposed as part of the Medicare Modernization Act of 2003. The purpose of this study was to identify the "true cost" associated with drug-related handling for the preparation and delivery of chemotherapy doses to estimate the impact of changing reimbursement schema by Medicare. Two academic medical outpatient infusion centers and 2 community cancer centers provided data used to estimate all costs (excluding drug cost) associated with the preparation of chemotherapy doses. The data included both fixed costs (drug storage, space, equipment, and information resources) and variable costs (insurance management, inventory, waste management, pharmacy staff payroll, supplies, and shipping). The average cost for the preparation of chemotherapy doses across all sites was dollar 34.27 (range, dollar 32.08-dollar 41.23). A time-and-motion study was also performed to determine what tasks were conducted by pharmacy staff and how much time was spent in the preparation of the top 15 chemotherapeutic drugs and regimens used in the 4 sites. Data from the 4 centers was projected to show that if 3,990,495 million chemotherapy infusions were administered to a national Medicare population in 2003, when multiplied by the average cost of preparation for infusions determined by the current study (dollar 34.27), the estimated total annual cost to Medicare for chemotherapy preparation by pharmacists is dollar 136,754,263.65. The pharmacists spent most of their days (90% or more) performing tasks directly related to the preparation of these agents. These data provide scientific support for the consideration of appropriate reimbursement for chemotherapy services provided by pharmacists to Medicare beneficiaries. PMID:16507268

    Biological oncology products are integral to cancer treatment, but their high costs pose challenges to patients, families, providers, and insurers. The introduction of biosimilar agents—molecules that are similar in structure, function, activity, immunogenicity, and safety to the original biological drugs—provide opportunities both to improve healthcare access and outcomes, and to reduce costs. Several international regulatory pathways have been developed to expedite entry of biosimilars into global marketplaces. The first wave of oncology biosimilar use was in Europe and India in 2007. Oncology biosimilars are now widely marketed in several countries in Europe, and in Australia, Japan, China, Russia, India, and South Korea. Their use is emerging worldwide, with the notable exception of the USA, where several regulatory and cost barriers to biosimilar approval exist.

    FTIR spectroscopy is used to study mammary-gland tissues of mice with a sarcoma tumor (strain 180). Spectral features that are typical of malignant tumors are revealed in the FTIR spectra in the sarcoma-tumor tissues. Tumor tissues are studied after treatment using coordination compounds based on palladium complexes with 3-amino-1-hydroxypropylidene-1,1-diphosphonic acid and zoledronic acid. A therapeutic effect is not revealed after treatment using palladium complex with 3-amino-1-hydroxypropylidene-1,1-diphosphonic acid. The suppression of tumor growth amounts to 59% when palladium complexes with zoledronic acid are used. Suppression of tumor growth is accompanied by variations in spectral characteristics. With respect to diagnostic features, the FTIR spectra of tumor tissues after treatment with the palladium complexes with zoledronic acid are similar to the FTIR spectra of tissues that are free of malignant tumors. Specific spectroscopic characteristics that make it possible to control the chemotherapy of oncological pathologies are determined.

    The administration of chemotherapy to children with cancer is a high-risk process that must be performed in a safe and consistent manner with high reliability. Clinical trials play a major role in the treatment of children with cancer; conformance to chemotherapy protocol requirements and accurate documentation in the medical record are critical. Inconsistencies in the administration and documentation of chemotherapy were identified as opportunities for errors to occur. A major process improvement was initiated to establish best practices for nurses who administer chemotherapy to children. An interdisciplinary team was formed to evaluate the current process and to develop best practices based on current evidence, protocol requirements, available resources, and safety requirements. The process improvement focused on the establishment of standardized and safe administration techniques, exact administration times, and consistent electronic documentation that could easily be retrieved in medical record audits. Quality improvement tools including SBAR (Situation, Background, Assessment, Recommendation), process mapping, PDSA (Plan, Do. Study, Act) cycles, and quality metrics were used with this process improvement. The team established best practices in chemotherapy administration to children that have proven to be safe and reliable. Follow-up data have demonstrated that the project was highly successful and improved accuracy, patient and nurse safety, and effectiveness of chemotherapy administration. PMID:26668214

    A new Soviet preparation for colour lymphography--chromolymphotrast--is presented in this paper. Radiopaque lymphography with the use of chromolymphotrast was carried out upon more than 50 patients with carcinoma of the uterine cervix and of the body of the womb. Besides, there is information concerning a successful use of the chromolymphotrast in cases of cancer of the vulva, mammary gland and rectum. Colour lymphography with the use of chromolymphotrast contributes to a more complete removal of lymphatic collectors. After a preliminary lymphography surgical interventions have acquired a radical character in 93.6% of operations on lymphatic nodes, thus adding to a decrease of the incidence rate of regional recurrences. The national medical industry has proceeded to the production of the preparation, which builds up the conditions for a broad use of colour radiopaque lymphography in oncology. PMID:664167

    Summary Background Cost-covering in-patient care is increasingly important for hospital providers in Germany, especially with regard to expensive oncological pharmaceuticals. Additional payments (Zusatzentgelte; ZE) on top of flat rate diagnose-related group (DRG) reimbursement can be claimed by hospitals for in-patient use of selected medications. To verify cost coverage of in-patient chemotherapies, the costs of medication were compared to their revenues. Method From January to June 2010, a retrospective cost-revenue study was performed at a German obstetrics/gynecology university clinic. The hospital's pharmacy list of inpatient oncological therapies for breast and gynecological cancer was checked for accuracy and compared with the documented ZEs and the costs and revenues for each oncological application. Results N = 45 in-patient oncological therapies were identified in n = 18 patients, as well as n = 7 bisphosphonate applications; n = 11 ZEs were documented. Costs for oncological medication were € 33,752. The corresponding ZE revenues amounted to only € 13,980, resulting in a loss of € 19,772. All in-patient oncological therapies performed were not cost-covering. Data discrepancy, incorrect documentation and cost attribution, and process aborts were identified. Conclusions Routine financial quality control at the medicine-pharmacy administration interface is implemented, with monthly comparison of costs and revenues, as well as admission status. Non-cost-covering therapies for in-patients should be converted to out-patient therapies. Necessary adjustments of clinic processes are made according to these results, to avoid future losses.

    Here, we report 2 patients with gastric cancer and peritoneal dissemination who were successfully treated with chemotherapy after undergoing treatment for an oncologic emergency caused by peritoneal dissemination. Case 1 involved obstruction of the sigmoid colon caused by peritoneal dissemination. After urgent colostomy, S-1/IP IV paclitaxel chemotherapy was introduced. The patient continued the therapy for 2 years and 2 months. Case 2 involved acute renal failure due to bilateral ureter obstruction and obstructive jaundice caused by peritoneal dissemination. This patient underwent emergency treatment consisting of Double-J ureteral stent insertion and endoscopic nasobiliary drainage. He was successfully started on chemotherapy with S-1/oxaliplatin/IP paclitaxel. He continued the therapy for 8 months without symptoms. Aggressive treatment might be effective for advanced gastric cancer showing oncologic emergency. PMID:26805263

    Hybrid imaging with integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) combines the advantages of the high-resolution anatomic data from MRI and functional imaging data from PET, and has the potential to improve the diagnostic evaluation of various types of cancers. The clinical oncologic applications of this newest hybrid imaging technology are evolving and substantial efforts are underway to define the role of PET/MRI in routine clinical use. The current published literature suggests that PET/MRI may play an important role in the evaluation of patients with certain types of malignancies, involving anatomic locations such as the pelvis and the liver. The purpose of this article is to review the current published PET/MRI literature in specific body oncologic applications. In addition, PET/MRI protocols and some of the technical issues of this hybrid imaging will be briefly discussed. J. Magn. Reson. Imaging 2016;44:265-276. PMID:27007987

    The National Cancer Institute clinical cooperative groups have been instrumental over the past 50 years in developing clinical trials and evidence-based process improvements for clinical oncology patient care. The cooperative groups are undergoing a transformation process as we further integrate molecular biology into personalized patient care and move to incorporate international partners in clinical trials. To support this vision, data acquisition and data management informatics tools must become both nimble and robust to support transformational research at an enterprise level. Information, including imaging, pathology, molecular biology, radiation oncology, surgery, systemic therapy, and patient outcome data needs to be integrated into the clinical trial charter using adaptive clinical trial mechanisms for design of the trial. This information needs to be made available to investigators using digital processes for real-time data analysis. Future clinical trials will need to be designed and completed in a timely manner facilitated by nimble informatics processes for data management. This paper discusses both past experience and future vision for clinical trials as we move to develop data management and quality assurance processes to meet the needs of the modern trial.

    The oncology clinics use different nursing care delivery models to provide chemotherapy treatment to cancer patients. Functional and primary care delivery models are the most commonly used methods in the clinics. In functional care delivery model, patients are scheduled for a chemotherapy appointment without considering availabilities of individual nurses, and nurses are assigned to patients according to patient acuities, nursing skill, and patient mix on a given day after the appointment schedule is determined. Patients might be treated by different nurses on different days of their treatment. In primary care delivery model, each patient is assigned to a primary nurse, and the patients are scheduled to be seen by the same nurse every time they come to the clinic for treatment. However, these clinics might experience high variability in daily nurse workload due to treatment protocols that should be followed strictly. In that case, part-time nurses can be utilized to share the excess workload of the primary nurses. The aim of this study is to develop optimization methods to reduce the time spent for nurse assignment and patient scheduling in oncology clinics that use different nursing care delivery models. For the functional delivery model, a multiobjective optimization model with the objectives of minimizing patient waiting times and nurse overtime is proposed to solve the nurse assignment problem. For the primary care delivery model, another multiobjective optimization model with the objectives of minimizing total overtime and total excess workload is proposed to solve the patient scheduling problem. Spreadsheet-based optimization tools are developed for easy implementation. Computational results show that the proposed models provide multiple nondominated solutions, which can be used to determine the optimal staffing levels. PMID:25595434

    Emotional distress (ED) is greater for oncology patients in comparison with the general population, and this has implications for the quality of life of the patient and his/her family, adherence to the treatment, and eventually, survivorship. In general, the detection of these symptoms is low, which explains the need for detection systems appropriate to the clinical reality of the oncology team. The objective of this study is to evaluate for the first time the usefulness of an ultra-brief screening instrument [distress thermometer (DT)], in a group of Chilean oncology patients. A total of 166 outpatients were evaluated at the Cancer Center of the Pontificia Universidad Católica de Chile, before starting chemotherapy. Two screening instruments were applied: Hospital Anxiety and Depression Scale (HADS) and DT. The application of HADS resulted in a prevalence of 32.7% of anxiety symptoms (HADS-A ≥ 8), 15.7% of depression symptoms (HADS-D ≥ 8), and 39.8% had a total score of HADS-T ≥ 11. The DT resulted in the prevalence of 32.5% of distress or ED (DT ≥ 5). The validity of the DT was evaluated as a screening tool in comparison with HADS, observing, in relation to the anxiety scale (HADS-A), a sensitivity of 88.9% and specificity of 78.4% (DT ≥ 4); depression (HADS-D), a sensitivity of 69.2% and specificity of 74.3% (DT ≥ 5); and in relation to the total scale (HADS-T), a sensitivity of 68.2% and specificity of 73.0% (DT ≥ 4). This study demonstrates the elevated prevalence of emotional symptoms in Chilean oncology patients, before the start of chemotherapy, and confirms the potential of the DT as a brief screening instrument with easy application. The DT will allow the clinician to increase the detection threshold in the Chilean oncology population, intervene in a timely manner, and contribute to the comprehensive handling of the oncology patient without affecting the time needed for assistance.

    Cancer-related pain is highly prevalent and often severe, and as a result is often one of the defining experiences for patients with malignancy. Patients and patients' families almost always live with the ever-present reality that cancer treatment and progression may be accompanied by pain. For patients nearing the end of life, most fear that their final days will be spent living with the terrible effects of the disease, the most important of which is pain. Despite this, there is far less systematic research on the mechanisms of cancer-related pain or on the development of new agents to reduce or eliminate pain in cancer patients compared with research to combat the disease itself. Further, even when the focus of research is treatment of the tumor, the effects of anticancer treatments on pain are often underreported in publications and other forums. To illustrate the relative drought in the cancer pain control area, there have been no new drugs approved for cancer-related pain in recent years. A number of methodologic and logistical challenges that hinder the ability to assess pain response in clinical trials are discussed in this article. Possible ways to address these challenges are also discussed. PMID:22046026

    The circadian timing system (CTS) controls several critical molecular pathways for cancer processes and treatment effects over the 24 hours, including drug metabolism, cell cycle, apoptosis, and DNA damage repair mechanisms. This results in the circadian time dependency of whole-body and cellular pharmacokinetics and pharmacodynamics of anticancer agents. However, CTS robustness and phase varies among cancer patients, based on circadian monitoring of rest- activity, body temperature, sleep, and/or hormonal secretion rhythms. Circadian disruption has been further found in up to 50% of patients with metastatic cancer. Such disruption was associated with poor outcomes, including fatigue, anorexia, sleep disorders, and short progression-free and overall survival. Novel, minimally invasive devices have enabled continuous CTS assessment in non-hospitalized cancer patients. They revealed up to 12-hour differences in individual circadian phase. Taken together, the data support the personalization of chronotherapy. This treatment method aims at the adjustment of cancer treatment delivery according to circadian rhythms, using programmable-in-time pumps or novel release formulations, in order to increase both efficacy and tolerability. A fixed oxaliplatin, 5-fluorouracil and leucovorin chronotherapy protocol prolonged median overall survival in men with metastatic colorectal cancer by 3.3 months as compared to conventional delivery, according to a meta-analysis (P=0.009). Further analyses revealed the need for the prevention of circadian disruption or the restoration of robust circadian function in patients on chronotherapy, in order to further optimize treatment effects. The strengthening of external synchronizers could meet such a goal, through programmed exercise, meal timing, light exposure, improved social support, sleep scheduling, and the properly timed administration of drugs that target circadian clocks. Chrono-rehabilitation warrants clinical testing for improving

    Studies in pediatric oncology have shown a positive effect of physical activity on disease- and treatment-related side effects. Although several reviews have approved the benefits of therapeutic exercise for adult cancer patients, no systematic review exists summarizing the evidence of physical activity in pediatric oncology. We identified a total of 17 studies using the PubMed database and Cochrane library. To evaluate the evidence, we used the evaluation system of the Oxford Center for Evidence-Based Medicine 2001. The findings confirm that clinical exercise interventions are feasible and safe, especially with acute lymphoblastic leukemia (ALL) patients and during medical treatment. No adverse effects have been reported. Positive effects were found on fatigue, strength, and quality of life. Single studies present positive effects on the immune system, body composition, sleep, activity levels, and various aspects of physical functioning. Child-specific aspects such as cognitive abilities, growth, adolescence, and reintegration into peer-groups, school, and sports have barely been taken into consideration. The evidence for exercise interventions in pediatric oncology is rated level "3." Although the results are very promising, future research of high methodological quality and focusing on child-specific aspects is needed to establish evidence-based exercise recommendations, particularly for childhood cancer patients.

    Chemotherapy may be indicated in head and neck cancer: as induction, associated with radiation therapy, or as a palliative solution, in case of local or locoregional progression if surgery and radiation therapy are contraindicated, and/or in case of metastatic progression. The most frequently used anticancer agents are platins, antimetabolites (5-fluorouracil, methotrexate) and taxanes. For several years now, in some indications, chemotherapy may be associated with targeted anti-EGFR antibody therapy. Prescription of chemotherapy and follow-up in head and neck cancer requires particular attention due to comorbidities related to alcohol abuse and smoking and frequent denutrition. Management thus requires close cooperation between the ENT physician, medical oncologists and radiation oncologists. PMID:26183547

    Lymphedema is a common late toxicity of cancer therapy. This article describes the rationale and process utilized by the Lymphedema Working Group for the revision and expansion of the Common Toxicity Criteria version 2 (CTC v2.0) lymphedema criteria to produce the CTC v3.0 lymphedema criteria. Established clinician-based rating scales and quantitative instruments are reviewed in this article. None of the extant rating scales have been formally validated, nor has their reliability been assessed. Drawbacks of current scales were considered in formulating CTC v3.0 criteria. Most rely exclusively on volume to diagnose and grade lymphedema. This imposes significant clinical limitations, particularly in the assessment of toxicity in oncology clinical trials. Volume-based rating scales are of little value in rating the severity of bilateral limb and nonlimb edema. Problems with nonvolumetric staging systems (eg, CTC v2.0) include insufficient detail to permit useful discrimination of severity among the majority of lymphedema patients. Technologies for objectively quantifying lymphedema have been developed and validated. Although these are briefly reviewed, it is recognized that cost and access issues limit their widespread clinical utility and, as such, were not considered in developing the CTC v3.0 criteria. The CTC v3.0 lymphedema criteria adopted several innovations. Principle among these was the decision to generate separate criteria for volumetric increase, dermal changes, and subcutaneous fibrosis. We anticipate the use of the new CTC v3.0 lymphedema criteria to begin in mid-2003 for grading the key clinical features of this disorder in oncology clinical trials. The purpose of this article is to familiarize the reader with (1) background on the clinical features of lymphedema, (2) information on established lymphedema rating systems, (3) the consensus process and rationale of the Lymphedema Working Group, (4) the new CTC v3.0, and (5) quantitative techniques for

    Following previous metronomic meetings in Marseille (2011), Milano (2014), and Mumbai (2016), the first Latin American metronomic meeting was held in the School of Medical Sciences, National University of Rosario, Rosario, Argentina on 27 and 28 of May, 2016. For the first time, clinicians and researchers with experience in the field of metronomics, coming from different countries in Latin America, had the opportunity of presenting and discussing their work. The talks were organised in three main sessions related to experience in the pre-clinical, and clinical (paediatric and adult) areas. The different presentations demonstrated that the fields of metronomic chemotherapy and repurposing drugs in oncology, known as metronomics, constitute a branch of cancer therapy in permanent evolution, which have strong groups working in Latin America, both in the preclinical and the clinical settings including large, adequately designed randomised studies. It was shown that metronomics offers treatments, which, whether they are combined or not with the standard therapeutic approaches, are not only effective but also minimally toxic, with the consequent improvement of the patient’s quality of life, and inexpensive, a feature very important in low resource clinical settings. The potential use of metronomic chemotherapy was proposed as a cost/effective treatment in low-/middle-income countries, for adjuvant therapy in selected tumours. The fundamental role of the governmental agencies and non-governmental alliances, as the Metronomic Global Health Initiative, in supporting this research with public interest was underlined.

    Metabolomics, an omic science in systems biology, is the global quantitative assessment of endogenous metabolites within a biological system. Either individually or grouped as a metabolomic profile, detection of metabolites is carried out in cells, tissues, or biofluids by either nuclear magnetic resonance spectroscopy or mass spectrometry. There is potential for the metabolome to have a multitude of uses in oncology, including the early detection and diagnosis of cancer and as both a predictive and pharmacodynamic marker of drug effect. Despite this, there is lack of knowledge in the oncology community regarding metabolomics and confusion about its methodologic processes, technical challenges, and clinical applications. Metabolomics, when used as a translational research tool, can provide a link between the laboratory and clinic, particularly because metabolic and molecular imaging technologies, such as positron emission tomography and magnetic resonance spectroscopic imaging, enable the discrimination of metabolic markers noninvasively in vivo. Here, we review the current and potential applications of metabolomics, focusing on its use as a biomarker for cancer diagnosis, prognosis, and therapeutic evaluation. PMID:19147747

    Compelling evidence supports the transition of next generation sequencing (NGS) technology from a research environment into clinical practice. Before NGS technologies are fully adopted in the clinic, they should be thoroughly scrutinised for their potential as powerful diagnostic and prognostic tools. The importance placed on generating accurate NGS data, and consequently appropriate clinical interpretation, has stimulated much international discussion regarding the creation and implementation of strict guidelines and regulations for NGS clinical use. In the context of clinical oncology, NGS technologies are currently transitioning from a clinical research background into a setting where they will contribute significantly to individual patient cancer management. This paper explores the steps that have been taken, and those still required, for the transition of NGS into the clinical area, with particular emphasis placed on validation in the setting of clinical oncology.

    Grigsby PW. Radiation Therapy Oncology Group clinical trials for carcinoma of the cervix. The purpose of this paper is to review the primary data of the clinical trials performed by the Radiation Therapy Oncology Group (RTOG) for patients with carcinoma of the uterine cervix. The trials, their strengths, limitations, and the implications of the results are discussed. During the past 25 years there have been several clinical trials performed by the RTOG to test various hypotheses for improving local control and survival for patients with carcinoma of the uterine cervix. The major research themes that have been appraised are the use of hyperbaric oxygen, altered fractionation radiotherapy, hypoxic cell sensitization, chemo-sensitization, prophylactic paraaortic irradiation, and neutron radiotherapy. There are two general research themes. The initial RTOG trials for cervical cancer attempted to address the issues of tumor volume and hypoxic cells while the latter studies addressed these issues and the issue of micrometastatic disease. The phase III clinical trials performed by the RTOG have not demonstrated a local control or survival advantage in the experimental arm with the use of hyperbaric oxygen, split-course radiotherapy, hypoxic cell sensitization, or neutron radiotherapy. Acceptable toxicity and efficacy results were shown in phase II studies evaluating twice-daily irradiation and chemo-sensitization. The positive phase III trials were RTOG 79-20 which evaluated prophylactic paraaortic irradiation in patients with bulky stages IB, IIA, and IIB disease, and RTOG 90-01 which evaluated concurrent chemotherapy. Results of more recent clinical trials are pending their completion. PMID:11240808

    Aim In this article the aim is to provide a concise narrative review and inform the institutional experience at a referral center in Chile with the use of radio-chemotherapy in anal cancer. Background Cancer of the anus and anal canal is mainly a loco-regional disease. For years the standard of care has been concomitant radio-chemotherapy, which permits organ preservation and better local control than alternative surgical procedures. Materials and methods A retrospective analysis of 44 patients treated between 2002 and 2010 was performed. Local recurrence, distant recurrence and overall survival were analyzed with the Kaplan–Meier method. Relevant groups where compared with the log-rank test and univariate analysis were done with the Cox proportional hazards model. Results Median follow-up of the cohort was 56 months, with a minimum follow-up of at least 24 months. There was a significant difference between clinical stages in disease free survival (log-rank trend p < 0.001), and a significant difference in overall survival (OS) when comparing clinical stages that were grouped in stage I–IIIa and IIIB (log-rank p = 0.001). On univariate analysis, age older than 60, having received full treatment and dose above 45 Gy were all significantly related to OS (p < 0.05). An overall survival of 45% and disease free survival of 45% at 5 years were found in our series. Conclusions Our findings show that results at the Instituto de Radiomedicina in Chile are comparable to published literature. Dismal results in stage IIIb cases indicate much work remains in therapies to achieve loco-regional control in locally advanced cases. PMID:25061522

    We propose that the quantitative cancer biology community make a concerted effort to apply the methods of weather forecasting to develop an analogous theory for predicting tumor growth and treatment response. Currently, the time course of response is not predicted, but rather assessed post hoc by physical exam or imaging methods.

This is especially frustrating at a time when a panoplymore » of molecularly targeted therapies is available, and precision genetic or proteomic analyses of tumors are an established reality. By learning from the methods of weather and climate modeling, we submit that the forecasting power of biophysical and biomathematical modeling can be harnessed to hasten the arrival of a field of predictive oncology. With a successful theory of tumor forecasting, it should be possible to integrate large tumor specific datasets of varied types, and effectively defeat cancer one patient at a time.« less

    In May 1960, the Farmitalia CEO Dr. Bertini and the director of the Istituto Nazionale dei Tumori of Milan Prof. Bucalossi (talent scout and city's Mayor) signed a research agreement for the discovery and development up to clinical trials of new natural antitumor agents. This agreement can be considered as a pioneering and fruitful example of a translational discovery program with relevant transatlantic connections. Owing to an eclectic Streptomyces, found near Castel del Monte (Apulia), and to the skilled and motivated participants of both institutions, a new natural antitumor drug, daunomycin, was ready for clinical trials within 3 years. Patent interference by the Farmitalia French partner was overcome by the good quality of the Italian drug and by the cooperation between Prof. Di Marco, director of the Istituto Ricerche Farmitalia Research Laboratories for Microbiology and Chemotherapy, and Prof. Karnofsky, head of the Sloan-Kettering Cancer Institute of New York, leading to the first transatlantic clinical trials. The search for daunomycin's sister anthracyclines led to the discovery and development of adriamycin, one of the best drugs born in Milan. This was the second act prologue of the history of Italian antitumor discovery and clinical oncology, which started in July 1969 when Prof. Di Marco sent Prof. Bonadonna the first vials of adriamycin (doxorubicin) to be tested in clinical trials. This article reviews the Milan scene in the 1960s, a city admired and noted for the outstanding scientific achievements of its private and public institutions in drugs and industrial product discovery.

    Contract research organizations (CROs) represent a multibillion dollar industry that is firmly embedded in the contemporary clinical trial process. Over the past 30 years, and especially within the last decade, the reach of CROs has extended to service all phases of drug trials in an increasingly global research environment. The presence of CROs is particularly noticeable in medical oncology because of the large number of investigational compounds developed to treat cancer that are currently undergoing testing in human subjects. Although limited data are available with which to objectively define the effects that CROs have had on the clinical trial process, with the expansion of these organizations, several reports have called into question whether ethical and professional standards in research conduct are at times secondary to economic considerations. CROs can add considerable value to the clinical trial process, but difficulty communicating with CRO representatives and time spent answering trivial data queries generated by CROs are current obstacles for study site personnel interacting with CROs. Further study of the effect of the CRO industry on the clinical trial process is needed to ensure efficient data collection and patient safety while collaboratively developing novel therapies in an expedited fashion.

    Low functional literacy and low health literacy continue to be under-recognized and are associated with poorer patient health outcomes. Health literacy is a dynamic state influenced by how well a healthcare system delivers information and services that match patients’ abilities, needs and preferences. Oncology care poses considerable health literacy demands on patients who are expected to process high stakes information about complex multidisciplinary treatment over lengths of time. Much of the information provided to patients in clinical care and research is beyond their literacy levels. In this paper, we provide an overview of currently available guidelines and resources to improve how the needs of patients with diverse literacy skills are met by cancer care providers and clinics. We present recommendations for health literacy assessment in clinical practice and ways to enhance the usability of health information and services by improving written materials and verbal communication, incorporating multimedia and culturally appropriate approaches, and promoting health literacy in cancer care settings. The paper also includes a list of additional resources that can be used to develop and implement health literacy initiatives in cancer care clinics. PMID:20464884

    Purpose: Students applying to radiation oncology residency programs complete 1 or more radiation oncology clerkships. This study assesses student experiences and perspectives during radiation oncology clerkships. The impact of didactic components and number of clerkship experiences in relation to confidence in clinical competency and preparation to function as a first-year radiation oncology resident are evaluated. Methods and Materials: An anonymous, Internet-based survey was sent via direct e-mail to all applicants to a single radiation oncology residency program during the 2012-2013 academic year. The survey was composed of 3 main sections including questions regarding baseline demographic information and prior radiation oncology experience, rotation experiences, and ideal clerkship curriculum content. Results: The survey response rate was 37% (70 of 188). Respondents reported 191 unique clerkship experiences. Of the respondents, 27% (19 of 70) completed at least 1 clerkship with a didactic component geared towards their level of training. Completing a clerkship with a didactic component was significantly associated with a respondent's confidence to function as a first-year radiation oncology resident (Wilcoxon rank–sum P=.03). However, the total number of clerkships completed did not correlate with confidence to pursue radiation oncology as a specialty (Spearman ρ P=.48) or confidence to function as a first year resident (Spearman ρ P=.43). Conclusions: Based on responses to this survey, rotating students perceive that the majority of radiation oncology clerkships do not have formal didactic curricula. Survey respondents who completed a clerkship with a didactic curriculum reported feeling more prepared to function as a radiation oncology resident. However, completing an increasing number of clerkships does not appear to improve confidence in the decision to pursue radiation oncology as a career or to function as a radiation oncology resident.

    Metastatic pancreatic cancer (PC) has been associated with a considerably poor prognosis. Due to its toxicity, first-line combination chemotherapy is limited to patients with a good performance status (PS). Previously nab-paclitaxel plus gemcitabine has been demonstrated to improve the overall survival rate in patients with advanced pancreatic cancer with a good PS. The present study reports a case of a patient with metastatic PC with a poor PS (Eastern Cooperative Oncology Group 2) and a complex set of comorbidities treated with nab-paclitaxel plus gemcitabine as a first-line palliative therapy. Adjusted doses of nab-paclitaxel plus gemcitabine reached a favourable clinical, radiological and biochemical response in the present patient, which increased the quality of life for the patient. Eventually, the patient succumbed to acute cholangitis. Based on the results of the present study, nab-paclitaxel plus gemcitabine appears to be a favourable treatment as first-line palliative chemotherapy for patients with metastatic PC, comorbidities and poor PS.

  16. Cancer-related fatigue. Clinical practice guidelines in oncology.

    PubMed

    2003-07-01

    These guidelines propose a treatment algorithm in which patients are evaluated regularly for fatigue using a brief screening instrument, and are treated as indicated by their fatigue level. The algorithm's goal is to identify and treat all patients with fatigue that causes distress or interferes with their daily activities or functioning. Management of fatigue begins with primary oncology team members who perform the initial screening and either provide basic education and counseling or expand the initial screening to a more focused evaluation for moderate or higher levels of fatigue. At this point the patient is assessed for current disease and treatment status, a review of body systems, and an in-depth fatigue evaluation. In addition, the patient is assessed for the presence of seven treatable factors known to contribute to fatigue: pain, emotional distress, sleep disturbance, anemia, alterations in nutrition, deconditioning, and comorbidities. If any of these conditions are present, they should be treated according to practice guidelines, with referral to other care professionals as appropriate, and the patient's fatigue should be reevaluated regularly. If none of the seven factors are present or the fatigue is unresolved, selection of appropriate fatigue management and treatment strategies is considered within the context of the patient's clinical status: receiving active cancer treatment, receiving disease-free long-term follow-up, or receiving care at the end of life. Management of fatigue is cause-specific when conditions known to cause fatigue can be identified and treated. When specific causes, such as infection, fluid and electrolyte imbalances, or cardiac dysfunction, cannot be identified and corrected, nonpharmacologic and pharmacologic treatment of the fatigue should be considered. Nonpharmacologic interventions may include a moderate exercise program to improve functional capacity and activity tolerance, psychosocial programs to manage stress and

    Background Symptom cluster research is an emerging field in symptom management. The ability to identify symptom clusters that are specific to pediatric oncology patients may lead to improved understanding of symptoms’ underlying mechanisms among patients of all ages. Objective The purpose of this study, in a sample of children and adolescents with cancer who underwent a cycle of myelosuppressive chemotherapy, was to compare the number and types of symptom clusters identified using patients’ ratings of symptom occurrence and symptom severity. Interventions/Methods Children and adolescents with cancer (10 to 18 years of age; N=131) completed the Memorial Symptom Assessment Scale 10–18 on the day they started a cycle of myelosuppressive chemotherapy, using a one week recall of experiences. Symptom data based on occurrence and severity ratings were examined using Exploratory Factor Analysis (EFA). The defined measurement model suggested by the best EFA model was then examined with a latent variable analysis. Results Three clusters were identified when symptom occurrence ratings were evaluated which were classified as a chemotherapy sequelae cluster, mood disturbance cluster, and a neuropsychological discomforts cluster. Analysis of symptom severity ratings yielded similar cluster configurations. Conclusions Cluster configurations remained relatively stable between symptom occurrence and severity ratings. The evaluation of patients at a common point in the chemotherapy cycle may have contributed to these findings. Implications for Practice Additional uniformity in symptom clusters investigations is needed to allow appropriate comparisons among studies. The dissemination of symptom clusters research methodology through publication and presentation may promote uniformity in this field. PMID:21921793

    Oncological treatments can lead to acute and chronic cancer related toxicities. In recent years, a large number of clinical studies have reported positive effects of exercise to the bio-psycho-social regeneration of cancer patients. However, very few evidence-based programs have been implemented into practice with little opportunity for cancer patients to engage in such programs. Reviews and RCT studies on exercise and cancer are showing that specific exercise programs have a positive impact on fatigue syndrome, urinary incontinence, lymphedema, polyneuropathy, arthralgia, and androgen deprivation related toxicities. With the increasing evidence for exercise oncology interventions, recommendations arising from clinical trials should be translated into clinical practice and this should be viewed as an important next step in this fast moving field of exercise oncology. For that the personalized treatment concept "Oncologic clinical exercise" (OTT) was developed. PMID:26402184

    Objective An area of need in cancer informatics is the ability to store images in a comprehensive database as part of translational cancer research. To meet this need, we have implemented a novel tandem database infrastructure that facilitates image storage and utilisation. Background We had previously implemented the Thoracic Oncology Program Database Project (TOPDP) database for our translational cancer research needs. While useful for many research endeavours, it is unable to store images, hence our need to implement an imaging database which could communicate easily with the TOPDP database. Methods The Thoracic Oncology Research Program (TORP) imaging database was designed using the Research Electronic Data Capture (REDCap) platform, which was developed by Vanderbilt University. To demonstrate proof of principle and evaluate utility, we performed a retrospective investigation into tumour response for malignant pleural mesothelioma (MPM) patients treated at the University of Chicago Medical Center with either of two analogous chemotherapy regimens and consented to at least one of two UCMC IRB protocols, 9571 and 13473A. Results A cohort of 22 MPM patients was identified using clinical data in the TOPDP database. After measurements were acquired, two representative CT images and 0–35 histological images per patient were successfully stored in the TORP database, along with clinical and demographic data. Discussion We implemented the TORP imaging database to be used in conjunction with our comprehensive TOPDP database. While it requires an additional effort to use two databases, our database infrastructure facilitates more comprehensive translational research. Conclusions The investigation described herein demonstrates the successful implementation of this novel tandem imaging database infrastructure, as well as the potential utility of investigations enabled by it. The data model presented here can be utilised as the basis for further development of other larger

  20. Tumor hypoxia: a new PET imaging biomarker in clinical oncology.

    PubMed

    Tamaki, Nagara; Hirata, Kenji

    2016-08-01

    Tumor hypoxia is associated with tumor progression and resistance to various treatments. Noninvasive imaging using positron emission tomography (PET) and F-18-labeled fluoromisonidazole (FMISO) was recently introduced in order to define and quantify tumor hypoxia. The FMISO uptake was closely correlated with pimonidazole immunohistochemistry and hypoxia-inducible factor 1 expression in basic studies. Tumor hypoxia in head and neck cancers and other tumors in a clinical setting may also indicate resistance to radiation and/or chemotherapy. Hypoxic imaging may thus play a new and important role for suitable radiation planning, including dose escalation and dose reduction based on the image findings. Such radiation-dose painting based on the findings of hypoxia may require high-performance PET imaging to provide high target-to-background ratio images and an optimal quantitative parameter to define the hypoxic region. A multicenter prospective study using data from a large number of patients is also warranted to test the clinical value of hypoxic imaging. PMID:26577447

    The effects of a therapeutic course of the combination of carboplatin and etoposide on platelet function have been evaluated in 10 pediatric patients with brain tumors. Platelet count, in vitro aggregation tests, P-selectin expression and agonist-induced ATP release were evaluated before, and 7 and 15 days after one cycle of chemotherapy. The analysis of the results demonstrated the presence of an in vitro platelet aggregation defect in response to collagen and arachidonic acid in all patients 7 days after therapy. A concomitant decrease of collagen- and arachidonic acid-induced ATP release was also observed. Both platelet aggregation and ATP release returned to baseline values 15 days after chemotherapy administration. Conversely, in vitro platelet aggregation and secretion induced by ADP and epinephrine were unaltered by carboplatin and etoposide administration. Furthermore, P-selectin expression was negative at baseline and did not change after chemotherapy. These results support the hypothesis that combination etoposide and carboplatin chemotherapy in pediatric patients is responsible for possible disturbances in biochemical pathways required for platelet secretion and aggregation.

    Purpose: The ability to quantify clinical trial–associated workload can have a significant impact on the efficiency and success of a research organization. However, methods to effectively estimate the number of research staff needed for clinical trial recruitment, maintenance, compliance, and follow-up are lacking. To address this need, the Wichita Community Clinical Oncology Program (WCCOP) developed and implemented an acuity-based workload assessment tool to facilitate assessment and balancing of workload among its research nursing staff. Methods: An acuity-based measurement tool was developed, assigning acuity scores for individual clinical trials using six trial-related determinants. Using trial acuity scores and numbers of patients per trial, acuity scores for individual research nursing staff were then calculated and compared on a monthly basis. Results: During the 11 years that data were collected, acuity scores increased from 65% to 181%. However, during this same period, WCCOP was able to decrease individual research nurse staff full-time equivalent (FTE) acuity scores and number of patients per FTE. These trends reflect the use of the acuity-based measurement tool to determine actual workload and use of the acuity data to direct hiring decisions. Conclusion: Clinical trial workload has been successfully measured and used to guide staffing by one community clinical oncology program. Further research is needed regarding its applicability to other research programs. PMID:23942924

    The molecular heterogeneity of cancer calls for individualized therapies to become the standard of care. It is now generally accepted that target-specific compounds require specific new development programs. But, even for new drugs with general mode of action (i.e., chemotherapy), tailored treatment approaches, such as specific schedules or combinations, have been shown to improve the therapeutic outcome. Therefore, the preclinical development of new therapeutic agents needs, next to the "classical pharmacodynamic studies", the implementation of integrative translational research (TR) as early as possible. New TR approaches, starting already at target identification and validation (TIV) will allow to defining the optimal patient population for clinical development, to tailor individual treatment of the tumor disease and to choose a rational basis among the manifold options for treatment combinations. We will discuss several examples from TR studies, which have initially been started to evaluate the molecular mode of action and to recognize mechanisms which can lead to resistance. Research was extended later to identify predictive response biomarkers and establish a rationale for combination with different therapies. A detailed gene expression analysis of lung cancer cells and apoptotic pathway interference studies in colon cancer cells provided insight in the molecular mechanisms of action. These new findings are correlated with results from other studies performed during the preclinical development program. We discuss pros and cons, successes and failures of our integrative preclinical development program and provide recommendations for future oncology projects. PMID:25841411

    Three models of care are described, including two models of multidisciplinary care for thoracic malignancies. The pros and cons of each model are discussed, the evidence supporting each is reviewed, and the need for more (and better) research into care delivery models is highlighted. Key stakeholders in thoracic oncology care delivery outcomes are identified, and the need to consider stakeholder perspectives in designing, validating and implementing multidisciplinary programs as a vehicle for quality improvement in thoracic oncology is emphasized. The importance of reconciling stakeholder perspectives, and identify meaningful stakeholder-relevant benchmarks is also emphasized. Metrics for measuring program implementation and overall success are proposed. PMID:26380186

    Summary The use of molecular tools to individualize health care, predict appropriate therapies and prevent adverse health outcomes has gained significant traction in the field of oncology, under the banner of “personalized medicine.” Enthusiasm for personalized medicine in oncology has been fueled by success stories of targeted treatments for a variety of cancers based on their molecular profiles. Though these are clear indications of optimism for personalized medicine, little is known about the ethical and social implications of personalized approaches in clinical oncology. The objective of this study is to assess how a range of stakeholders engaged in promoting, monitoring, and providing personalized medicine understand the challenges of integrating genomic testing and targeted therapies into clinical oncology. The study involved the analysis of in-depth interviews with 117 basic scientists, clinician-researchers, clinicians in private practice, health professional educators, representatives of funding agencies, medical journal editors, entrepreneurs, and insurers whose experiences and perspectives on personalized medicine span a wide variety of institutional and professional settings. Despite considerable enthusiasm for this shift, promoters, monitors and providers of personalized medicine identified four domains which will still provoke heightened ethical and social concerns: (1) informed consent for cancer genomic testing, (2) privacy, confidentiality, and disclosure of genomic test results, (3) access to genomic testing and targeted therapies in oncology, and (4) the costs of scaling up pharmacogenomic testing and targeted cancer therapies. These specific concerns are not unique to oncology, or even genomics. However, those most invested in the success of personalized medicine view oncologists’ responses to these challenges as precedent-setting because oncology is farther along the path of clinical integration of genomic technologies than other fields

    Purpose Bloodstream infections in pediatric hematology and oncology represent a major problem worldwide, but this has not been studied in Qatar. In this study, we investigated the burden of infection and the resistance pattern in the bacterial etiology, in the only tertiary pediatric hematology and oncology center in Qatar. Methods All pediatric cancer patients (n=185) were evaluated retrospectively during the period 2004–2011; a total of 70 (38%) patients were diagnosed with bloodstream infections. Bacterial etiology was determined, along with their susceptibility patterns. Neutropenia, duration of neutropenia, fever, duration of fever, and C-reactive protein (CRP) were evaluated throughout the study. Results A total of 70 patients (38%) were diagnosed with acute leukemias, lymphomas, solid tumors, or brain tumors; those patients experienced 111 episodes of bacteremia. The most common Gram-positive (n=64 [55%]) isolates were Staphylococcus epidermidis (n=26), Staphylococcus hominis (n=9), and Staphylococcus haemolyticus (n=7), and the common Gram-negative (n=52 [45%]) isolates were Klebsiella pneumoniae (n=14), Pseudomonas aeruginosa (n=10), and Escherichia coli (n=7). There was a significant association observed between fever with positive blood culture and different types of cancer (P=0.035). The majority of bacteremia (n=68 [61.3%]) occurred in nonneutropenic episodes. Elevated values of CRP (≥5 mg/L) were detected in 82 (95.3%) episodes and were negatively correlated with absolute neutrophil count (ANC) (r=−0.18; P=0.248) among all cases. However, the infection-related fatality rate was 2.2% (n=4), with three caused by Gram-negative pathogens. Multidrug resistant organisms were implicated in 33 (28.4%) cases and caused three of the mortality cases. Conclusion Multidrug resistant organisms cause mortality in pediatric cancer patients. Investigation of antimicrobial susceptibility of these organisms may guide successful antimicrobial therapy and improve

    Recent advances in supportive care and progress in the development and use of chemotherapy have considerably improved the prognosis of many children with malignancy, thus the need for intensive care admission and management is increasing, reaching about 40% of patients throughout the disease course. Cancer remains a major death cause in children, though outcomes have considerably improved over the past decades. Prediction of outcome for children with cancer in Pediatric Intensive Care Unit (PICU) obviously requires clinical guidelines, and these are not well defined, as well as admission criteria. Major determinants of negative outcomes remain severe sepsis/septic shock association and respiratory failure, deserving specific approach in children with cancer, particularly those receiving a bone marrow transplantation. A nationwide consensus should be achieved among pediatric intensivists and oncologists regarding the threshold clinical conditions requiring Intensive Care Unit (ICU) admission as well as specific critical care protocols. As demonstrated for the critically ill non-oncologic child, it appears unreasonable that pediatric patients with malignancy can be admitted to an adult Intensive Care Unit ICU. On a national basis a pool of refecence institutions should be identified and early referral to an oncologic PICU is warranted. PMID:21772950

    To simulate clinical trials to assess overall survival (OS) benefit of bevacizumab in combination with chemotherapy in selected patients with gastric cancer (GC), a modeling framework linking OS with tumor growth inhibition (TGI) metrics and baseline patient characteristics was developed. Various TGI metrics were estimated using TGI models and data from two phase III studies comparing bevacizumab plus chemotherapy vs. chemotherapy as first-line therapy in 976 GC patients. Time-to-tumor-growth (TTG) was the best TGI metric to predict OS. TTG, Eastern Cooperative Oncology Group (ECOG) score, albumin level, and Asian ethnicity were significant covariates in the final OS model. The model correctly predicted a decreased hazard ratio favorable to bevacizumab in patients with high baseline plasma VEGF-A above the median of 113.4 ng/L. Based on trial simulations, in trials enrolling patients with elevated baseline plasma VEGF-A (500 patients per arm), the expected hazard ratio was 0.82 (95% prediction interval: 0.70-0.95), independent of ethnicity.

    Non-clinical studies are necessary at each stage of the development of oncology drugs. Many experimental cancer models have been developed to investigate carcinogenesis, cancer progression, metastasis, and other aspects in cancer biology and these models turned out to be useful in the efficacy evaluation and the safety prediction of oncology drugs. While the diversity and the degree of engagement in genetic changes in the initiation of cancer cell growth and progression are widely accepted, it has become increasingly clear that the roles of host cells, tissue microenvironment, and the immune system also play important roles in cancer. Therefore, the methods used to develop oncology drugs should continuously be revised based on the advances in our understanding of cancer. In this review, we extensively summarize the effective use of those models, their advantages and disadvantages, ranges to be evaluated and limitations of the models currently used for the development and for the evaluation of oncology drugs.

    In the era of personalized medicine, diagnostic approaches are helping pharmaceutical and biotechnology sponsors streamline the clinical trial process. Molecular assays and diagnostic imaging are routinely being used to stratify patients for treatment, monitor disease, and provide reliable early clinical phase assessments. The importance of diagnostic approaches in drug development is highlighted by the rapidly expanding global cancer diagnostics market and the emergent attention of regulatory agencies worldwide, who are beginning to offer more structured platforms and guidance for this area. In this paper, we highlight the key benefits of using companion diagnostics and diagnostic imaging with a focus on oncology clinical trials. Nuclear imaging using widely available radiopharmaceuticals in conjunction with molecular imaging of oncology targets has opened the door to more accurate disease assessment and the modernization of standard criteria for the evaluation, staging, and treatment responses of cancer patients. Furthermore, the introduction and validation of quantitative molecular imaging continues to drive and optimize the field of oncology diagnostics. Given their pivotal role in disease assessment and treatment, the validation and commercialization of diagnostic tools will continue to advance oncology clinical trials, support new oncology drugs, and promote better patient outcomes.

    The introduction of hybrid PET/MRI systems allows simultaneous multimodality image acquisition of high technical quality. This technique is well suited for the brain, and particularly in dementia and neuro-oncology. In routine use combinations of well-established MRI sequences and PET tracers provide the most optimal and clinically valuable protocols. For dementia the [18F]-fluorodeoxyglucose (FDG) has merit with a simultaneous four sequence MRI protocol of 20 min supported by supplementary statistical reading tools and quantitative measurements of the hippocampal volume. Clinical PET/MRI using [18F]-fluoro-ethyl-tyrosine (FET) also abide to the expectations of the adaptive and versatile diagnostic tool necessary in neuro-oncology covering both simple 20 min protocols for routine treatment surveillance and complicated 90 min brain and spinal cord protocols in pediatric neuro-oncology under general anesthesia. The clinical value of adding advanced MRI sequences in multiparametric imaging setting, however, is still undocumented. PMID:27593248

    Extravasation of cytostatics occurs when an infusion containing a cytotoxic drug leaks into the surrounding perivascular and subcutaneous tissues. Incidence of cytostatic extravasation is found to be 0.1-6% according to the literature. Depending on the severity of complications, pain, loss of function in the extremities, or in extreme cases tissue necrosis necessitating an amputation may develop, drawing consequences like delay or interruption of the chemotherapy. Extent of complications is greatly influenced by the type of medication administered, general condition of the patient, and professional preparedness of staff providing the oncological health service. The protocol recently implemented in the National Institute of Oncology is a short, compact guidance for physicians and nurses providing oncological care, so by quick and adequate management of extravasation cases, severe complications could be prevented. More complex practical guidelines including algorithms could be created as a result of a wider collaboration, with the help of which oncological health professionals could easily cope with this rare problem. The authors describe in their review the implementation of the use of dry warm and cold packs, dymethylsulfoxide and hyaluronidase and their function within the algorithm of extravasation treatment.

    Background: This study was performed to examine quality of life's dimensions and its relationship with some clinical and demographic characteristics on women with breast cancer under chemotherapy referred to the oncology hospital, Isfahan University of medical sciences, Iran. Methods: This Cross sectional study was conducted among 330 breast cancer patients with simple sampling methodology. Data collection instrument included a questionnaire contains 2 parts (clinical and demographic characteristics information and version 2.0 of the SF-36 questionnaire (the international version). The data were analyzed with 99% confidence by carried out using SPSS18 with using descriptive and analytic statistics. Results: The majority of subjects’ quality of life was moderate (53.93%). there was a statistically significant relationship between quality of life among breast cancer patients with chemotherapy sessions (P < 0.05, df =4, χ2 = 16.37). One way Analysis Of Variance (ANOVA) suggested the absence of any significant relationship between quality of life with marital status (f = 0.21; P = 0.92) and employment status (f = 0.26; P = 0.77). Also, Spearman test showed the absence of any significant relationship between quality of life with age (P = 0.60), and the elapsed duration from diagnosis (P = 0.68), however Spearman test showed significant relationship between quality of life and education status (P = 0.002, r = -0.84). Conclusion: With regard to results of this study, there was a direct correlation between the number of chemotherapy sessions and patients quality of life. The attitude of the population toward chemotherapy is usually inhibiting and negative, so patients, students and nurses should be trained about chemotherapy efficacy to improve their attitude about chemotherapy, which in turn would lead to improvement of the patients’ quality of life.

    Despite advances in biomedical research that have deepened our understanding of cancer hallmarks, resulting in the discovery and development of targeted therapies, the success rates of oncology drug development remain low. Opportunities remain for objective dose selection informed by exposure-response understanding to optimize the benefit-risk balance of novel therapies for cancer patients. This review article discusses the principles and applications of modeling and simulation approaches across the lifecycle of development of oncology therapeutics. Illustrative examples are used to convey the value gained from integration of quantitative clinical pharmacology strategies from the preclinical-translational phase through confirmatory clinical evaluation of efficacy and safety.

    Oncology nurses and their patients are frequently on the cutting edge of new therapies and interventions that support coping, health, and healing. Reiki is a practice that is requested with increasing frequency, is easy to learn, does not require expensive equipment, and in preliminary research, elicits a relaxation response and helps patients to feel more peaceful and experience less pain. Those who practice Reiki report that it supports them in self-care and a healthy lifestyle. This article will describe the process of Reiki, review current literature, present vignettes of patient responses to the intervention, and make recommendations for future study. PMID:18515247

    Background Double-checking is widely recommended as an essential method to prevent medication errors. However, prior research has shown that the concept of double-checking is not clearly defined, and that little is known about actual practice in oncology, for example, what kind of checking procedures are applied. Objective To study the practice of different double-checking procedures in chemotherapy administration and to explore nurses' experiences, for example, how often they actually find errors using a certain procedure. General evaluations regarding double-checking, for example, frequency of interruptions during and caused by a check, or what is regarded as its essential feature was assessed. Methods In a cross-sectional survey, qualified nurses working in oncology departments of 3 hospitals were asked to rate 5 different scenarios of double-checking procedures regarding dimensions such as frequency of use in practice and appropriateness to prevent medication errors; they were also asked general questions about double-checking. Results Overall, 274 nurses (70% response rate) participated in the survey. The procedure of jointly double-checking (read-read back) was most commonly used (69% of respondents) and rated as very appropriate to prevent medication errors. Jointly checking medication was seen as the essential characteristic of double-checking—more frequently than ‘carrying out checks independently’ (54% vs 24%). Most nurses (78%) found the frequency of double-checking in their department appropriate. Being interrupted in one's own current activity for supporting a double-check was reported to occur frequently. Regression analysis revealed a strong preference towards checks that are currently implemented at the responders' workplace. Conclusions Double-checking is well regarded by oncology nurses as a procedure to help prevent errors, with jointly checking being used most frequently. Our results show that the notion of independent checking needs to be

    There is a growing importance in failure analysis in cancer management. In these analyses locoregional failure as the cause of death emerges as a significant problem in many tumor sites, e.g., head and neck cancer, gynecologic cancer, genitourinary cancer. Because of these data, the radiation oncology community has attributed high priority to research efforts to improve locoregional control. These efforts include the following: (1) brachytherapy alone or with external beam radiation therapy or surgery; (2) intraoperative radiation therapy; (3) hyperthermia with radiation therapy; (4) particle irradiation (protons, neutrons, stripped nuclei, and pions); and (5) routes of administration of the treatment, including infusional (intravenous) chemotherapy with radiation therapy, intraarterial monoclonal antibodies with radionuclides, and intraarterial chemotherapy with radiation therapy. Each area of investigation is discussed.

    Purpose To provide current recommendations about the prophylaxis and treatment of venous thromboembolism (VTE) in patients with cancer. Methods PubMed and the Cochrane Library were searched for randomized controlled trials, systematic reviews, meta-analyses, and clinical practice guidelines from November 2012 through July 2014. An update committee reviewed the identified abstracts. Results Of the 53 publications identified and reviewed, none prompted a change in the 2013 recommendations. Recommendations Most hospitalized patients with active cancer require thromboprophylaxis throughout hospitalization. Routine thromboprophylaxis is not recommended for patients with cancer in the outpatient setting. It may be considered for selected high-risk patients. Patients with multiple myeloma receiving antiangiogenesis agents with chemotherapy and/or dexamethasone should receive prophylaxis with either low–molecular weight heparin (LMWH) or low-dose aspirin. Patients undergoing major surgery should receive prophylaxis starting before surgery and continuing for at least 7 to 10 days. Extending prophylaxis up to 4 weeks should be considered in those undergoing major abdominal or pelvic surgery with high-risk features. LMWH is recommended for the initial 5 to 10 days of treatment for deep vein thrombosis and pulmonary embolism as well as for long-term secondary prophylaxis (at least 6 months). Use of novel oral anticoagulants is not currently recommended for patients with malignancy and VTE because of limited data in patients with cancer. Anticoagulation should not be used to extend survival of patients with cancer in the absence of other indications. Patients with cancer should be periodically assessed for VTE risk. Oncology professionals should educate patients about the signs and symptoms of VTE. PMID:25605844

    Uncontrolled pain is one of the most feared and debilitating symptoms among cancer patients, and many suffer unnecessarily from suboptimal pain control. Cancer-related pain is often multidimensional and can affect all aspects of a patient's life. Hence, achieving adequate pain relief among cancer patients involves a proper assessment of psychosocial, spiritual, and physical pain issues, matched with an individualized treatment plan involving pharmacologic, nonpharmacologic, and procedural therapies when appropriate. Providing effective pain relief can help ease the overall burden of disease among oncology patients while helping them tolerate cancer-directed therapies and achieve the most optimal quality of life throughout all phases of the disease continuum. In this review, the authors will discuss the syndromes, assessment of, and treatment for cancer-related pain in the outpatient setting. PMID:26862909

    Despite the widespread use of 5-HT3 receptor antagonist antiemetics such as ondansetron and granistron, up to 70% of patients with cancer receiving highly emetogenic chemotherapy agents experience postchemotherapy nausea and vomiting. Delayed postchemotherapy nausea (nausea that occurs >/= 24 hours after chemotherapy administration) and anticipatory nausea (nausea that develops before chemotherapy administration, in anticipation of it) are poorly controlled by currently available antiemetic agents. Scientific studies suggest that ginger (Zingiber officinale) might have beneficial effects on nausea and vomiting associated with motion sickness, surgery, and pregnancy. In 2 small studies of patients with cancer receiving chemotherapy, addition of ginger to standard antiemetic medication further reduced the severity of postchemotherapy nausea. This article describes a phase II/III randomized, dose-finding, placebo-controlled, double-blind clinical trial to assess the efficacy of ginger for nausea associated with chemotherapy for cancer. The study is currently being conducted by private practice oncology groups that are funded by the National Cancer Institute's Community Clinical Oncology Program and affiliated with the University of Rochester Cancer Center Community Clinical Oncology Program Research Base.

    Cellular heterogeneity is a fundamental characteristic of many cancers. A lack of cellular homogeneity contributes to difficulty in designing targeted oncological therapies. Therefore, the development of novel methods to determine and characterize oncologic cellular heterogeneity is a critical next step in the development of novel cancer therapies. Single-cell sequencing (SCS) technology has been recently employed for analyzing the genetic polymorphisms of individual cells at the genome-wide level. SCS requires (1) precise isolation of the single cell of interest; (2) isolation and amplification of genetic material; and (3) descriptive analysis of genomic, transcriptomic, and epigenomic data. In addition to targeted analysis of single cells isolated from tumor biopsies, SCS technology may be applied to circulating tumor cells, which may aid in predicting tumor progression and metastasis. In this paper, we provide an overview of SCS technology and review the current literature on the potential application of SCS to clinical oncology and research. PMID:27313981

    The American Society of Clinical Oncology (ASCO) has long affirmed that the recognition and management of individuals with an inherited susceptibility to cancer are core elements of oncology care. ASCO released its first statement on genetic testing in 1996 and updated that statement in 2003 and 2010 in response to developments in the field. In 2014, the Cancer Prevention and Ethics Committees of ASCO commissioned another update to reflect the impact of advances in this area on oncology practice. In particular, there was an interest in addressing the opportunities and challenges arising from the application of massively parallel sequencing-also known as next-generation sequencing-to cancer susceptibility testing. This technology introduces a new level of complexity into the practice of cancer risk assessment and management, requiring renewed effort on the part of ASCO to ensure that those providing care to patients with cancer receive the necessary education to use this new technology in the most effective, beneficial manner. The purpose of this statement is to explore the challenges of new and emerging technologies in cancer genetics and provide recommendations to ensure their optimal deployment in oncology practice. Specifically, the statement makes recommendations in the following areas: germline implications of somatic mutation profiling, multigene panel testing for cancer susceptibility, quality assurance in genetic testing, education of oncology professionals, and access to cancer genetic services.

    Purpose: Workload level and sources of stressors have been implicated as sources of error in multiple settings. We assessed workload levels and sources of stressors among radiation oncology professionals. Furthermore, we explored the potential association between workload and the frequency of reported radiotherapy incidents by the World Health Organization (WHO). Methods and Materials: Data collection was aimed at various tasks performed by 21 study participants from different radiation oncology professional subgroups (simulation therapists, radiation therapists, physicists, dosimetrists, and physicians). Workload was assessed using National Aeronautics and Space Administration Task-Load Index (NASA TLX). Sources of stressors were quantified using observational methods and segregated using a standard taxonomy. Comparisons between professional subgroups and tasks were made using analysis of variance ANOVA, multivariate ANOVA, and Duncan test. An association between workload levels (NASA TLX) and the frequency of radiotherapy incidents (WHO incidents) was explored (Pearson correlation test). Results: A total of 173 workload assessments were obtained. Overall, simulation therapists had relatively low workloads (NASA TLX range, 30-36), and physicists had relatively high workloads (NASA TLX range, 51-63). NASA TLX scores for physicians, radiation therapists, and dosimetrists ranged from 40-52. There was marked intertask/professional subgroup variation (P<.0001). Mental demand (P<.001), physical demand (P=.001), and effort (P=.006) significantly differed among professional subgroups. Typically, there were 3-5 stressors per cycle of analyzed tasks with the following distribution: interruptions (41.4%), time factors (17%), technical factors (13.6%), teamwork issues (11.6%), patient factors (9.0%), and environmental factors (7.4%). A positive association between workload and frequency of reported radiotherapy incidents by the WHO was found (r = 0.87, P value=.045

    Background The approval of epoetin biosimilars in the European Union requires extensive scientific evaluation and stringent regulatory procedures, including post-marketing studies. The ORHEO (place of biOsimilaRs in the therapeutic management of anaemia secondary to chemotherapy in HaEmatology and Oncology) study was an observational, longitudinal, multicentre study performed in France to evaluate the efficacy and safety of biosimilar epoetins for the treatment of chemotherapy-induced anaemia (CIA) in the clinical setting. Methods Patients >18 years with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for treatment with an epoetin biosimilar were included in this study. Patient characteristics were recorded at baseline along with anaemia-related information, such as observed and target Hb (as chosen by the treating clinician), brand and dose of epoetin biosimilar prescribed, and details of any other treatments. Patients were then followed-up at 3 and 6 months. The primary endpoint was Hb response (defined as Hb reaching ≥10 g/dL, an increase of Hb ≥1 g/dL since inclusion visit or reaching physician-defined target Hb, with no blood transfusions in the 3 weeks prior to measurement). Other endpoints included adverse events, achievement of target Hb and associated treatments. Results Overall, 2333 patients >18 years (mean age 66.5 years) with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for biosimilar epoetin treatment were included. 99.9% of patients received epoetin zeta (median dose 30,000 IU/week). Mean baseline Hb was 9.61 g/dL, with 35.6% of patients having moderate anaemia (Hb 8–9.5 g/dL). Hb response was achieved in 81.6% and 86.5% of patients at 3 and 6 months, respectively. Overall mean change in Hb level was 1.52 ± 1.61 and 1.72 ± 1.61 g/dL at 3 and 6 months, respectively. Transfusion and thromboembolic event rates were 9

    2013-01-01

    Fatigue is a debilitating and pervasive complication of cancer and cancer care. Clinical research investigating potential therapies is hindered by variability in patient histories, different metrics for measuring fatigue, and environmental factors that may affect fatigue. The purpose of this study was to establish an animal model of chemotherapy-related fatigue. Female HSD:ICR mice were treated with doxorubicin (2.5 mg/kg) or saline in 2 cycles (days 1 through 3 and 10 through 12). After treatment, mice were individually housed in cages equipped with running wheels. Open-field activity and motor coordination were examined after each cycle of treatment and after each week of wheel running. In a separate cohort, modafinil (50 mg/kg) was assessed as a potential treatment for fatigue. Doxorubicin administration resulted in greater than 30% less wheel running compared with that of saline controls. Activity differences were specific to wheel running: neither distance traveled in the open field nor motor coordination according to the rotarod test differed between groups. Compared with control values, RBC counts in the doxorubicin group were decreased on days 15 and 22 but recovered to control levels by study completion. Modafinil was efficacious in increasing wheel running in the doxorubicin group. The current results establish an animal model of chemotherapy-related fatigue that recapitulates the physical symptoms of cancer-related fatigue as manifested as decreased voluntary activity. This model is sensitive to pharmaceutical intervention and can be used to screen potential treatments for fatigue. PMID:24326224

    Hierarchical processes spanning several orders of magnitude of both space and time underlie nearly all cancers. Multi-scale statistical, mathematical, and computational modeling methods are central to designing, implementing and assessing treatment strategies that account for these hierarchies. The basic science underlying these modeling efforts is maturing into a new discipline that is close to influencing and facilitating clinical successes. The purpose of this review is to capture the state-of-the-art as well as the key barriers to success for multi-scale modeling in clinical oncology. We begin with a summary of the long-envisioned promise of multi-scale modeling in clinical oncology, including the synthesis of disparate data types into models that reveal underlying mechanisms and allow for experimental testing of hypotheses. We then evaluate the mathematical techniques employed most widely and present several examples illustrating their application as well as the current gap between pre-clinical and clinical applications. We conclude with a discussion of what we view to be the key challenges and opportunities for multi-scale modeling in clinical oncology. PMID:27384942

    The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1,073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.This guideline was developed through a collaboration between the American Cancer Society and the American Society of Clinical Oncology and has been published jointly by invitation and consent in both CA: A Cancer Journal for

    Summary The ability to control the growth of new blood vessels would be an extraordinary therapeutic tool for many disease processes. Too often, the promises of discoveries in the basic science arena fail to translate to clinical success. While several anti angiogenic therapeutics are now FDA approved, the envisioned clinical benefits have yet to be seen. The ability to clinically non-invasively image angiogenesis would potentially be used to identify patients who may benefit from anti-angiogenic treatments, prognostication/risk stratification and therapy monitoring. This article reviews the current and future prospects of implementing angiogenesis imaging in the clinic. PMID:22132017

    Compassion fatigue (CF) is "debilitating weariness brought about by repetitive, empathic responses to the pain and suffering of others" (LaRowe, 2005, p. 21). The work performed by oncology nurses, and the experiences of the people they care for, place oncology nurses at high risk for CF (Pierce et al., 2007; Ferrell & Coyle, 2008). Thus oncology nurses were chosen as the study focus. This paper details a descriptive exploratory qualitative research study that investigated the experience of CF in Canadian clinical oncology registered nurses (RNs). A conceptual stress process model by Aneshensel, Pearlin, Mullan, Zarit, and Whitlatch (1995) that considers caregivers' stress in four domains provided the study framework (see Figure 1). Nineteen study participants were recruited through an advertisement in the Canadian Oncology Nursing Journal (CONJ). The advertisement directed potential participants to a university-based online website developed for this study. Participants completed a questionnaire and wrote a narrative describing an experience with CF and submitted these through the secure research website. Data were analyzed thematically. Five themes include: defining CF, causes of CF, factors that worsen CF, factors that lessen CF, and outcomes of CF. Participants had limited knowledge about CF, about lack of external support, and that insufficient time to provide high quality, care may precipitate CF. The gap between quality of care nurses wanted to provide and what they were able to do, compounded by coexisting physical and emotional stress, worsened CF. CF was lessened by colleague support, work-life balance, connecting with others, acknowledgement, and maturity and experience. Outcomes of CF included profound fatigue of mind and body, negative effects on personal relationships, and considering leaving the specialty. Recommendations that may enhance oncology nurse well-being are provided. PMID:21661623

    There is currently a rapid evolution of clinical practices based on the introduction of patient stratification and molecular diagnosis that is likely to improve health outcomes. Building on a strong research base, complemented by strong support from clinicians and health authorities, the oncology field is at the forefront of this evolution. Yet, clinical research is still facing many challenges that need to be addressed in order to conduct necessary studies and effectively translate medical breakthroughs based on personalized medicine into standards of care. Leveraging its universal health care system and on resources developed to support oncology clinical research, Canada is well positioned to join the international efforts deployed to address these challenges. Available resources include a broad range of structures and funding mechanisms, ranging from direct clinical trial support to post-marketing surveillance. Here, we propose a clinical model for the introduction of innovation for precision medicine in oncology that starts with patients' and clinicians' unmet needs to initiate a cycle of discovery, validation, translation and sustainability development.

    Photoacoustic imaging has evolved into a clinically translatable platform with the potential to complement existing imaging techniques for the management of cancer, including detection, characterization, prognosis, and treatment monitoring. In photoacoustic imaging, tissue is optically excited to produce ultrasonographic images that represent a spatial map of optical absorption of endogenous constituents such as hemoglobin, fat, melanin, and water or exogenous contrast agents such as dyes and nanoparticles. It can therefore provide functional and molecular information that allows noninvasive soft-tissue characterization. Photoacoustic imaging has matured over the years and is currently being translated into the clinic with various clinical studies underway. In this review, the current state of photoacoustic imaging is presented, including techniques and instrumentation, followed by a discussion of potential clinical applications of this technique for the detection and management of cancer.

    Quality assurance in radiotherapy (RT) has been an integral aspect of cooperative group clinical trials since 1970. In early clinical trials, data acquisition was nonuniform and inconsistent and computational models for radiation dose calculation varied significantly. Process improvements developed for data acquisition, credentialing, and data management have provided the necessary infrastructure for uniform data. With continued improvement in the technology and delivery of RT, evaluation processes for target definition, RT planning, and execution undergo constant review. As we move to multimodality image-based definitions of target volumes for protocols, future clinical trials will require near real-time image analysis and feedback to field investigators. The ability of quality assurance centers to meet these real-time challenges with robust electronic interaction platforms for imaging acquisition, review, archiving, and quantitative review of volumetric RT plans will be the primary challenge for future successful clinical trials.

    The purposes of this study, in oncology outpatients receiving chemotherapy (n = 926), were to: describe the occurrence of different types of pain (ie, no pain, only noncancer pain [NCP], only cancer pain [CP], or both CP and NCP) and evaluate for differences in demographic, clinical, and symptom characteristics, and quality of life (QOL) among the 4 groups. Patients completed self-report questionnaires on demographic and symptom characteristics and QOL. Patients who had pain were asked to indicate if it was or was not related to their cancer or its treatment. Medical records were reviewed for information on cancer and its treatments. In this study, 72.5% of the patients reported pain. Of the 671 who reported pain, 21.5% reported only NCP, 37.0% only CP, and 41.5% both CP and NCP. Across the 3 pain groups, worst pain scores were in the moderate to severe range. Compared with the no pain group, patients with both CP and NCP were significantly younger, more likely to be female, have a higher level of comorbidity, and a poorer functional status. In addition, these patients reported: higher levels of depression, anxiety, fatigue, and sleep disturbance; lower levels of energy and attentional function; and poorer QOL. Patients with only NCP were significantly older than the other 3 groups. The most common comorbidities in the NCP group were back pain, hypertension, osteoarthritis, and depression. Unrelieved CP and NCP continue to be significant problems. Oncology outpatients need to be assessed for both CP and NCP conditions. PMID:26683234

    Concerns for patient safety persist in clinical oncology. Within several nonmedical areas (eg, aviation, nuclear power), concepts from Normal Accident Theory (NAT), a framework for analyzing failure potential within and between systems, have been successfully applied to better understand system performance and improve system safety. Clinical oncology practice is interprofessional and interdisciplinary, and our therapies often have narrow therapeutic windows. Thus, many of our processes are, in NAT terms, interactively complex and tightly coupled within and across systems and are therefore prone to unexpected behaviors that can result in substantial patient harm. To improve safety at the University of North Carolina, we have applied the concepts of NAT to our practice to better understand our systems' behavior and adopted strategies to reduce complexity and coupling. Furthermore, recognizing that we cannot eliminate all risks, we have stressed safety mindfulness among our staff to further promote safety. Many specific examples are provided herein. The lessons from NAT are translatable to clinical oncology and may help to promote safety. PMID:26182183

    Observational evidence has established a relationship between obesity and cancer risk and outcomes. Interventional studies have demonstrated the feasibility and benefits of lifestyle change after cancer diagnosis, and guidelines recommend weight management and regular physical activity in cancer survivors; however, lifestyle interventions are not a routine part of cancer care. The ASCO Research Summit on Advancing Obesity Clinical Trials in Cancer Survivors sought to identify the knowledge gaps that clinical trials addressing energy balance factors in cancer survivors have not answered and to develop a roadmap for the design and implementation of studies with the potential to generate data that could lead to the evidence-based incorporation of weight management and physical activity programs into standard oncology practice. Recommendations highlight the need for large-scale trials evaluating the impact of energy balance interventions on cancer outcomes, as well as the concurrent conduct of studies focused on dissemination and implementation of interventions in diverse populations of cancer survivors, including answering critical questions about the degree of benefit in key subgroups of survivors. Other considerations include the importance of incorporating economic metrics into energy balance intervention trials, the need to establish intermediate biomarkers, and the importance of integrating traditional and nontraditional funding sources. Establishing lifestyle change after cancer diagnosis as a routine part of cancer care will require a multipronged effort to overcome barriers related to study development, funding, and stakeholder engagement. Given the prevalence of obesity and inactivity in cancer survivors in the United States and elsewhere, energy balance interventions hold the potential to reduce cancer morbidity and mortality in millions of patients, and it is essential that we move forward in determining their role in cancer care with the same care and

    2014-06-01

    The use of the cannabis plant for various medical indications by cancer patients has been rising significantly in the past few years in several European countries, the US and Israel. The increase in use comes from public demand for the most part, and not due to a scientific basis. Cannabis chemistry is complex, and the isolation and extraction of the active ingredient remain difficult. The active agent in cannabis is unique among psychoactive plant materials, as it contains no nitrogen and, thus, is not an alkaloid. Alongside inconclusive evidence of increased risks of lung and head and neck cancers from prolonged smoking of the plant produce, laboratory evidence of the anti-cancer effects of plant components exists, but with no clinical research in this direction. The beneficial effects of treatment with the plant, or treatment with medicine produced from its components, are related to symptoms of the disease: pain, nausea and vomiting, loss of appetite and weight loss. The clinical evidence of the efficacy of cannabis for these indications is only partial. However, recent scientific data from studies with THC and cannabidiol combinations report the first clinical indication of cancer-related pain relief. The difficulties of performing research into products that are not medicinal, such as cannabis, have not allowed a true study of the cannabis plant extract although, from the public point of view, such studies are greatly desirable.

    Purpose Children's Oncology Group study AALL00P2 was designed to assess the feasibility and safety of adding nelarabine to a BFM 86–based chemotherapy regimen in children with newly diagnosed T-cell acute lymphoblastic leukemia (T-ALL). Patients and Methods In stage one of the study, eight patients with a slow early response (SER) by prednisone poor response (PPR; ≥ 1,000 peripheral blood blasts on day 8 of prednisone prephase) received chemotherapy plus six courses of nelarabine 400 mg/m2 once per day; four patients with SER by high minimal residual disease (MRD; ≥ 1% at day 36 of induction) received chemotherapy plus five courses of nelarabine; 16 patients with a rapid early response (RER) received chemotherapy without nelarabine. In stage two, all patients received six 5-day courses of nelarabine at 650 mg/m2 once per day (10 SER patients [one by MRD, nine by PPR]) or 400 mg/m2 once per day (38 RER patients; 12 SER patients [three by MRD, nine by PPR]). Results The only significant difference in toxicities was decreased neutropenic infections in patients treated with nelarabine (42% with v 81% without nelarabine). Five-year event-free survival (EFS) rates were 73% for 11 stage one SER patients and 67% for 22 stage two SER patients treated with nelarabine versus 69% for 16 stage one RER patients treated without nelarabine and 74% for 38 stage two RER patients treated with nelarabine. Five-year EFS for all patients receiving nelarabine (n = 70) was 73% versus 69% for those treated without nelarabine (n = 16). Conclusion Addition of nelarabine to a BFM 86–based chemotherapy regimen was well tolerated and produced encouraging results in pediatric patients with T-ALL, particularly those with a SER, who have historically fared poorly.

    Therapeutic options for the treatment of malignant brain tumors have been limited, in part, because of the presence of the blood-brain barrier. For this reason, the Sixth Annual Meeting of the Blood-Brain Barrier Disruption Consortium, the focus of which was the "Importance of Dose Intensity in Neuro-Oncology Clinical Trials," was convened in April 2000, at Government Camp, Mount Hood, Oregon. This meeting, which was supported by the National Cancer Institute, the National Institute of Neurological Disorders and Stroke, and the National Institute of Deafness and Other Communication Disorders, brought together clinicians and basic scientists from across the U.S. to discuss the role of dose intensity and enhanced chemotherapy delivery in the treatment of malignant brain tumors and to design multicenter clinical trials. Optimizing chemotherapy delivery to the CNS is crucial, particularly in view of recent progress identifying certain brain tumors as chemosensitive. The discovery that specific constellations of genetic alterations can predict which tumors are chemoresponsive, and can therefore more accurately predict prognosis, has important implications for delivery of intensive, effective chemotherapy regimens with acceptable toxicities. This report summarizes the discussions, future directions, and key questions regarding dose-intensive treatment of primary CNS lymphoma, CNS relapse of systemic non-Hodgkin's lymphoma, anaplastic oligodendroglioma, high-grade glioma, and metastatic cancer of the brain. The promising role of cytoenhancers and chemoprotectants as part of dose-intensive regimens for chemosensitive brain tumors and development of improved gene therapies for malignant gliomas are discussed.

    The use of procalcitonin (PCT) as an early marker of infectious episodes in cancer patients is still controversial. We performed a MEDLINE search of peer-reviewed articles published between January 1990 and December 2015, and finally we analysed 15 articles. PCT seems to have a good diagnostic value of infectious episodes in cancer patients and its accuracy seems greater if we consider major events, such as bloodstream infections and sepsis. Serial evaluations of this protein seem to be more accurate in the diagnostic phase and useful to predict outcome and response to antibacterial treatment. On the other hand, some issues have yet to be solved, such as the use of a validated method of determination, the definition of a standard cut-off, and the heterogeneity among different settings of patients (e.g. early versus advanced-stage cancer, or haematological versus solid tumours). However, it is credible to think that PCT use in everyday clinical practice, preferably in combination with other clinical or laboratory tests, might be of help in finding and detecting early infectious complications in cancer patients.

    Cancer cachexia is a syndrome characterized by a marked weight loss, anorexia, asthenia and anemia. The degree of cachexia is inversely correlated with the survival time of the patient and it always implies a poor prognosis. Lean body mass depletion is one of the main features of cachexia and it involves not only skeletal muscle but also affects cardiac protein. The cachectic state is invariably associated with the presence and growth of the tumour and leads to a malnutrition status due to the induction of anorexia or decreased food intake. In addition, the competition for nutrients between the tumour and the host leads to an accelerated starvation state which promotes severe metabolic disturbances in the host, including hypermetabolism which leads to an increased energetic inefficiency. Unfortunately, at the clinical level, cachexia is not treated until the patient suffers from a considerable weight loss and wasting. Therefore, it is of great interest to analyze possible early markers of the syndrome. In the present review both metabolic and hormonal markers are described. Although the search for the cachectic factor(s) started a long time ago, and although many scientific and economic efforts have been devoted to its discovery, we are still a long way from fully understanding the underlying basis for this syndrome. The suggested mediators (associated with both depletion of fat stores and muscular tissue) can be divided into two categories: of tumour origin (produced and released by the neoplasm) and humoural factors (mainly cytokines). One of the aims of the present review is to summarize and evaluate the different catabolic mediators (both humoural and tumoural) involved in cancer cachexia, since they may represent targets for clinical investigations. Additionally, an overview of the main therapeutic approaches for the treatment of the cachectic syndrome is presented. PMID:17485280

    While most children receive acute myeloid leukemia (AML) chemotherapy as inpatients, there is variability in timing of discharge after chemotherapy completion. This study compared treatment-related morbidity, mortality and cumulative hospitalization in children with AML who were discharged after chemotherapy completion (early discharge) and those who remained hospitalized. Chart abstraction data for 153 early discharge-eligible patients enrolled on a Children's Oncology Group trial were compared by discharge strategy. Targeted toxicities included viridans group streptococcal (VGS) bacteremia, hypoxia and hypotension. Early discharge occurred in 11% of courses post-Induction I. Re-admission occurred in 80-100%, but median hospital stay was 7 days shorter. Patients discharged early had higher rates of VGS (adjusted risk ratio (aRR) = 1.67, 95% CI = 1.11-2.51), hypoxia (aRR = 1.92, 95% CI = 1.06-3.48) and hypotension (aRR = 4.36, 95% CI = 2.01-9.46), but there was no difference in mortality. As pressure increases to shorten hospitalizations, these results have important implications for determining discharge practices in pediatric AML. PMID:26727639

    The American Society of Clinical Oncology (ASCO) is a global community of health care professionals whose stated purpose is to "make a world of difference" by improving cancer care around the world. Unfortunately, cancer survival rates vary significantly among countries with differing financial and infrastructural resources. Because ASCO is a professional oncology society committed to conquering cancer through research, education, prevention, and delivery of high-quality patient care, it is ideally suited to address this issue. ASCO could bring together oncology professionals and other necessary stakeholders from around the world to improve cancer care and lessen suffering for patients worldwide. As part of the ongoing commitment of ASCO to the future of cancer care, the Leadership Development Program was created to foster the leadership skills of early and midcareer oncologists and provide these participants with a working knowledge of the depth and breadth of the organization. As participants in the inaugural class of the ASCO Leadership Development Program, we were charged with investigating how ASCO might favorably affect cancer prevention and treatment in resource-poor countries in a cost-effective, scalable, and sustainable fashion. ASCO can significantly influence cancer care in low- and middle-income countries through a comprehensive approach that promotes cancer awareness and education, improves clinical practice by identifying and removing barriers to delivery of quality cancer care, and fosters innovation to initiate novel solutions to complex problems.

Scholars and policymakers have recently begun to devote increased attention to these issues, but only a few tangible resources exist to guide clinical oncologists in developing strategies for dealing with drug shortages on a recurring basis. This article discusses existing information from the scholarly literature, policy analyses, and other relevant sources and seeks to provide practical ethical guidance to the broad audience of oncology professionals who are increasingly confronted with such cases in their practice. We begin by providing a brief overview of the history, causes, and regulatory context of oncology drug shortages in the U.S., followed by a discussion of ethical frameworks that have been proposed in this setting. We conclude with practical recommendations for ethical professional behavior in these increasingly common and challenging situations. PMID:24449096

    During the 3rd congress of the European Society of Pharmacogenomics and Personalised Therapy (ESPT) in Budapest in 2015, a preliminary meeting was held aimed at establishing a pediatric individualized treatment in oncology and hematology committees. The main purpose was to facilitate the transfer and harmonization of pharmacogenetic testing from research into clinics, to bring together basic and translational research and to educate health professionals throughout Europe. The objective of this review was to provide the attendees of the meeting as well as the larger scientific community an insight into the compiled evidence regarding current pharmacogenomics knowledge in pediatric oncology. This preliminary evaluation will help steer the committee's work and should give the reader an idea at which stage researchers and clinicians are, in terms of personalizing medicine for children with cancer. From the evidence presented here, future recommendations to achieve this goal will also be suggested. PMID:27618021

    Mucosal melanomas constitute 1.3% of all melanomas and they may develop in any mucosal membrane. Conjunctival melanomas (0.5/million/year) and melanomas in the sinonasal cavity (0.5/million/year) are the most common, followed by anorectal melanomas (0.4/million/year) and melanomas in the oral cavity (0.2/million/year). Anorectal melanoma occurs slightly more often in females, whereas oral melanoma has a male predilection. Mucosal melanoma most commonly develops in a patient's sixth or seventh decade of life, and no differences between races have been found except for sinonasal melanoma and conjunctival melanoma, which are very rare in Black people. The symptoms are not tumour-specific and are related to the organ system affected, and the disease is most often diagnosed at an advanced clinical stage. The diagnosis of a primary tumour is difficult, and metastatic cutaneous melanoma and choroidal melanoma must be excluded. Mutations in KIT are frequently found, while BRAF and NRAS mutations are rarely found - except in conjunctival melanomas that carry BRAF mutations. Mutations in the TERT promotor region are also found in mucosal melanomas. Complete surgical resection with free margins is the treatment of choice. The prognosis is poor, with the 5-year survival rate ranging from 0% (gastric melanoma) to 80% (conjunctival melanoma). PMID:27004972

    Background: Granulocyte Colony Stimulating Factors (GCSF) is high-cost agents commonly recommended for primary and secondary prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia. GCSFs have been shown to be beneficial in some patient subgroups, although they are probably overused in clinical settings. The American Society of Clinical Oncology (ASCO) guidelines summarize current data on the appropriate use of CSFs. The aim of this study was to assess and audit the use of GCSF in a tertiary care center according to the recommendation of ASCO guideline. Subjects and Methods: A prospective observational study from November 2014 to June 2015 was performed on all patients prescribed with filgrastim in the large teaching hospital (Isfahan, Iran). Data was collected on demographics, indication, dosing regimen and duration of treatment, the Absolute Neutrophil Count (ANC) and patient outcome. Results: 91 patients were recorded over the period of the study. 63.7% of prescription complied with the ASCO guideline. Febrile neutropenia post chemotherapy/radiotherapy was the most common appropriate indication (29.3%) followed by primary prophylaxis (25.8%). Fourteen (32%) patients showed ANC recovery in 1-3 days and 16 (37%) within 4-7 days. Ten patients (23%) showed no recovery. The overall mortality was 8 (8.8%) patients. Conclusion: This study revealed that at least one-third of prescribed GCSF was not in accordance with ASCO guideline. Considering the high cost of GCSF in our country and limitation of our resources, we proposed cost-effectiveness studies on GCSF treatment and also the development of a national guideline for optimizing GCSF use.

    Glioblastoma patients have a poor prognosis, even after surgery, radiotherapy, and chemotherapy with temozolomide or 1,3-bis(2-chloroethy)-1-nitrosourea. We developed an in vitro recovery model using neurosphere cultures to analyze the efficacy of chemotherapy treatments, and tested whether glioblastoma neurosphere initiating cells are resistant. Concentrations of chemotherapy drugs that inhibit neurosphere formation are similar to clinically relevant doses. Some lines underwent a transient cell cycle arrest and a robust recovery of neurosphere formation. These results indicate that glioblastoma neurospheres can regrow after treatment with chemotherapy drugs. This neurosphere recovery assay will facilitate studies of chemo-resistant subpopulations and methods to enhance glioblastoma therapy. PMID:20435409

    Purpose To determine long-term survival and associated prognostic factors after intraperitoneal (IP) chemotherapy in patients with advanced ovarian cancer. Patients and Methods Data from Gynecologic Oncology Group protocols 114 and 172 were retrospectively analyzed. Cox proportional hazards regression models were used for statistical analyses. Results In 876 patients, median follow-up was 10.7 years. Median survival with IP therapy was 61.8 months (95% CI, 55.5 to 69.5), compared with 51.4 months (95% CI, 46.0 to 58.2) for intravenous therapy. IP therapy was associated with a 23% decreased risk of death (adjusted hazard ratio [AHR], 0.77; 95% CI, 0.65 to 0.90; P = .002). IP therapy improved survival of those with gross residual (≤ 1 cm) disease (AHR, 0.75; 95% CI, 0.62 to 0.92; P = .006). Risk of death decreased by 12% for each cycle of IP chemotherapy completed (AHR, 0.88; 95% CI, 0.83 to 0.94; P < .001). Factors associated with poorer survival included: clear/mucinous versus serous histology (AHR, 2.79; 95% CI, 1.83 to 4.24; P < .001), gross residual versus no visible disease (AHR, 1.89; 95% CI, 1.48 to 2.43; P < .001), and fewer versus more cycles of IP chemotherapy (AHR, 0.88; 95% CI, 0.83 to 0.94; P < .001). Younger patients were more likely to complete the IP regimen, with a 5% decrease in probability of completion with each year of age (odds ratio, 0.95; 95% CI, 0.93 to 0.96; P < .001). Conclusion The advantage of IP over intravenous chemotherapy extends beyond 10 years. IP therapy enhanced survival of those with gross residual disease. Survival improved with increasing number of IP cycles. PMID:25800756

    It is imperative that the thrust of clinical practice in the ensuing years would be to develop personalized management model for various disorders. PET-computed tomography (PET-CT) based molecular functional imaging has been increasingly utilized for assessment of tumor and other nonmalignant disorders and has the ability to explore disease phenotype on an individual basis and address critical clinical decision making questions related to practice of personalized medicine. Hence, it is essential to make a concerted systematic effort to explore and define the appropriate place of PET-CT in personalized clinical practice in each of malignancies, which would strengthen the concept further. The potential advantages of PET based disease management can be classified into broad categories: (1) Traditional: which includes assessment of disease extent such as initial disease staging and restaging, treatment response evaluation particularly early in the course and thus PET-CT response adaptive decision for continuing the same regimen or switching to salvage schedules; there has been continuous addition of newer application of PET based disease restaging in oncological parlance (eg, Richter transformation); (2) Recent and emerging developments: this includes exploring tumor biology with FDG and non-FDG PET tracers. The potential of multitracer PET imaging (particularly new and novel tracers, eg, 68Ga-DOTA-TOC/NOC/TATE in NET, 68Ga-PSMA and 18F-fluorocholine in prostate carcinoma, 18F-fluoroestradiol in breast carcinoma) has provided a scientific basis to stratify and select appropriate targeted therapies (both radionuclide and nonradionuclide treatment), a major boost for individualized disease management in clinical oncology. Integrating the molecular level information obtained from PET with structural imaging further individualizing treatment plan in radiation oncology, precision of interventions and biopsies of a particular lesion and forecasting disease prognosis.

    Despite much progress in the management of malignant diseases, the number of new cases and cancer-related deaths continues to rise around the world. More than half of new cases occur in economically developing countries, where more than two thirds of cancer deaths are expected. However, implementation of all necessary steps to accomplish the dissemination of state-of-the-art prevention, diagnosis, and management will require increased allocation of resources, and, more importantly, harmonization of the efforts of hundreds of national and international public health agencies, policy-setting bodies, governments, pharmaceutical companies, and philanthropic organizations. More than 30% of the members of the American Society of Clinical Oncology (ASCO) reside and practice outside US borders, and more than half of attendees at all of the scientific congresses and symposia organized by ASCO are international. As cancer has become an increasingly global disease, ASCO has evolved as a global organization. The ASCO Board of Directors currently includes members from France, Brazil, and Canada. In 2013, the ASCO Board of Directors identified a number of strategic priorities for the future. Recognizing the importance of non-US members to the society, their first strategic priority was improving the society's service to non-US members and defining these members' identity in the international oncology community. This article reviews current ASCO activities in the international arena and its future plans in global oncology. PMID:26578614

    2015-01-01

    In oncology trials, overall survival (OS) is considered the most reliable and preferred endpoint to evaluate the benefit of drug treatment. Other relevant variables are also collected from patients for a given drug and its indication, and it is important to characterize the dynamic effects and links between these variables in order to improve the speed and efficiency of clinical oncology drug development. However, the drug-induced effects and causal relationships are often difficult to interpret because of temporal differences. To address this, population pharmacokinetic–pharmacodynamic (PKPD) modelling and parametric time-to-event (TTE) models are becoming more frequently applied. Population PKPD and TTE models allow for exploration towards describing the data, understanding the disease and drug action over time, investigating relevance of biomarkers, quantifying patient variability and in designing successful trials. In addition, development of models characterizing both desired and adverse effects in a modelling framework support exploration of risk-benefit of different dosing schedules. In this review, we have summarized population PKPD modelling analyses describing tumour, tumour marker and biomarker responses, as well as adverse effects, from anticancer drug treatment data. Various model-based metrics used to drive PD response and predict OS for oncology drugs and their indications are also discussed. PMID:24134068

    The evidence base for the effectiveness of surgical interventions is relatively poor and data from large, randomized prospective studies are rare with often a poor quality. Many efforts have been made to increase the number of high quality randomized trials in surgery and theoretical proposals have been put forward to improve the situation, but practical implementation of these proposals is seriously lacking. The consequences of this policy are not trivial; with very few patients included in surgical oncology trials, this represents wasted opportunity for advances in cancer treatment. In this review, we cover the difficulties inherent to clinical research in surgical oncology, such as quality control, equipoise, accrual, and funding and promote alternative designs to the randomized controlled trial. Although the classic randomized controlled trial has a valid but limited place in surgical oncology, other prospective designs need to be promoted as a new deal. This new deal not only implicates surgeons but also journal editors, tender jury, as well as regulatory bodies to cover legal gaps currently surrounding surgical innovation. PMID:26610367

    Answer questions and earn CME/CNE The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.

    Objective. To examine the clinical characteristics and financial charges associated with treating adult cancer patients receiving chemotherapy in outpatient clinics who presented to the emergency department (ED) with neutropenia. Design and Setting. A retrospective audit was conducted across two health services involving ED episodes and subsequent hospital admissions of patients who received chemotherapy through day oncology from January 1 to December 31, 2007 and presented to the ED with neutropenia. ED data were collected from the Victorian Emergency Minimum Dataset and charges were collected from Health Information Services. Descriptive and bivariate statistics were used to describe the patient and clinical characteristics and financial outcomes, and to explore associations between these factors. Results. In total, 200 neutropenic episodes in 159 outpatients were seen in the ED over the survey period. The mean patient age was 56.6 years (standard deviation, 13.2 years) and 47.2% were male. Overall, 70.0% of ED episodes were triaged as Australasian Triage Scale 2 (emergency). The median ED wait time was 10 minutes and the median ED length of stay was 6.8 hours. The median charge for each ED episode was $764.08 Australian dollars. The total combined ED and inpatient charge per episode was in the range of $144.27–$174,732.68, with a median charge of $5,640.87. Conclusions. This study provides important insights into the clinical and economic burden of neutropenia from both the ED and inpatient perspectives. Alternative treatment models, such as outpatient treatment, early discharge programs or prophylactic interventions to reduce the clinical and economic burden of neutropenia on our health system, must be explored.

    There have been inexorable improvements in gynecologic radiation oncology through technologically advances, 3-dimensional imaging, and clinical research. Investment in these 3 critical areas has improved, and will continue to improve, the lives of patients with gynecologic cancer. Advanced technology delivery in gynecologic radiation oncology is challenging owing to the following: (1) setup difficulties, (2) managing considerable internal organ motion, and (3) responding to tumor volume reduction during treatment. Image guidance is a potential route to solve these problems and improve delivery to tumor and sparing organs at risk. Imaging with positron emission tomography-computed tomography and magnetic resonance imaging are contributing significantly to improved accuracy in diagnosis, treatment, and follow-up in cancer of the cervix. Functional imaging by exploiting tumor biology may improve prognosis and treatment. Clinical trials have been the greatest mechanism to improve and establish standards of care in women with vulvar, endometrial, and cervical cancer. There have been multiple technological advances and practice changing trials within the past several decades. Many important questions remain in optimizing care for women with gynecologic malignancies. The performance of clinical trials will be advanced with the use of consistent language (ie, similar staging system and criteria), eligibility criteria that fit the research question, end points that matter, adequate statistical power, complete follow-up, and prompt publication of mature results.

    Background: Breast cancer (BC) represents the highest incidence of malignancy in women throughout the world. Medicinal fungi can stimulate the body, reduce side-effects associated with chemotherapy and improve the quality of life in patients with cancer. Aim: To evaluate the effects of dietary supplementation of Agaricus sylvaticus on clinical and nutritional parameters in BC patients undergoing chemotherapy. Materials and Methods: A randomized, placebo-controlled, double-blind, clinical trial was carried out at the Oncology Clinic, Hospital of the Federal District-Brazil from September 2007 to July 2009. Forty six patients with BC, Stage II and III, were randomly assigned to receive either nutritional supplement with A. sylvaticus (2.1 g/day) or placebo. Patients were evaluated during treatment period. Results: Patient supplemented with A. sylvaticus improved in clinical parameters and gastrointestinal functions. Poor appetite decreased by 20% with no changes in bowel functions (92.8%), nausea and vomiting (80%). Conclusion: Dietary supplementation with A. sylvaticus improved nutritional status and reduced abnormal bowel functions, nausea, vomiting, and anorexia in patients with BC receiving chemotherapy.

    This Vision 20/20 paper considers what computational advances are likely to be implemented in clinical radiation oncology in the coming years and how the adoption of these changes might alter the practice of radiotherapy. Four main areas of likely advancement are explored: cloud computing, aggregate data analyses, parallel computation, and automation. As these developments promise both new opportunities and new risks to clinicians and patients alike, the potential benefits are weighed against the hazards associated with each advance, with special considerations regarding patient safety under new computational platforms and methodologies. While the concerns of patient safety are legitimate, the authors contend that progress toward next-generation clinical informatics systems will bring about extremely valuable developments in quality improvement initiatives, clinical efficiency, outcomes analyses, data sharing, and adaptive radiotherapy.

    2016-03-01

    Chemotherapy-induced hair loss is one of the most devastating side effects of cancer treatment. To study the effects of chemotherapeutic agents on the hair follicle, a number of experimental models have been proposed. Yoon et al. report that transplantation of human scalp hair follicles onto chemotherapy-treated immunodeficient mice serves as an excellent in vivo model for chemotherapy-induced hair loss. Yoon et al. demonstrate that (i) the response of human hair follicles grafted onto immunodeficient mice to cyclophosphamide resembles the key features of the chemotherapy-induced hair loss seen in patients with cancer and (ii) this human in vivo model for chemotherapy-induced hair loss is closer to clinical reality than to any earlier models. Undoubtedly, this model will serve as a valuable tool for analyses of the mechanisms that underlie this devastating side effect of anti-cancer therapy. PMID:26902124

    Multidisciplinary approaches that incorporate nonclinical pharmacologic and toxicologic characterization of small-molecule oncology drugs into clinical development programs may facilitate improved benefit-risk profiles and clinical toxicity management in patients. The performance of the current nonclinical safety-testing scheme was discussed, highlighting current strengths and areas for improvement. While current nonclinical testing appears to predict the clinical outcome where the prevalence of specific adverse effects are high, nonclinical testing becomes less reliable for predicting clinical adverse effects that occur infrequently, as with some kinase inhibitors. Although adverse effects associated with kinase inhibitors can often be predicted on the basis of target biology, drugs can be promiscuous and inhibit targets with poorly defined function and associated risks. Improvements in adverse effect databases and better characterization of the biologic activities of drug targets may enable better use of computational modeling approaches in predicting adverse effects with kinase inhibitors. Assessing safety of a lead candidate in parallel with other drug properties enables incorporation of a molecule's best features during chemical design, eliminates the worst molecules early, and permits timely investigation/characterization of toxicity mechanisms for identified liabilities. A safety lead optimization and candidate identification strategy that reduces intrinsic toxicity and metabolic risk and enhances selectivity can deliver selective kinase inhibitors that demonstrate on-target adverse effects identified nonclinically. Integrating clinical and nonclinical data during drug development can facilitate better identification and management of oncology drugs. Follow-up nonclinical studies may be used to better understand the risks in a given patient population and minimize or manage these risks more appropriately.

    Purpose: To identify factors significantly influencing accrual to clinical protocols by analyzing radiation Patterns of Care Study (PCS) surveys of 3,047 randomly selected radiotherapy (RT) patients. Methods and Materials: Patterns of Care Study surveys from disease sites studied for the periods 1992-1994 and 1996-1999 (breast cancer, n = 1,080; prostate cancer, n = 1,149; esophageal cancer, n = 818) were analyzed. The PCS is a National Cancer Institute-funded national survey of randomly selected RT institutions in the United States. Patients with nonmetastatic disease who received RT as definitive or adjuvant therapy were randomly selected from eligible patients at each institution. To determine national estimates, individual patient records were weighted by the relative contribution of each institution and patients within each institution. Data regarding participation in clinical trials were recorded. The factors age, gender, race, type of insurance, and practice type of treating institution (academic or not) were studied by univariate and multivariate analyses. Results: Overall, only 2.7% of all patients were accrued to clinical protocols. Of these, 57% were enrolled on institutional review board-approved institutional trials, and 43% on National Cancer Institute collaborative group studies. On multivariate analysis, patients treated at academic facilities (p = 0.0001) and white patients (vs. African Americans, p = 0.0002) were significantly more likely to participate in clinical oncology trials. Age, gender, type of cancer, and type of insurance were not predictive. Conclusions: Practice type and race significantly influence enrollment onto clinical oncology trials. This suggests that increased communication and education regarding protocols, particularly focusing on physicians in nonacademic settings and minority patients, will be essential to enhance accrual.

    Rates of obesity have increased significantly over the last three decades in the United States and globally. In addition to contributing to heart disease and diabetes, obesity is a major unrecognized risk factor for cancer. Obesity is associated with worsened prognosis after cancer diagnosis and also negatively affects the delivery of systemic therapy, contributes to morbidity of cancer treatment, and may raise the risk of second malignancies and comorbidities. Research shows that the time after a cancer diagnosis can serve as a teachable moment to motivate individuals to adopt risk-reducing behaviors. For this reason, the oncology care team—the providers with whom a patient has the closest relationships in the critical period after a cancer diagnosis—is in a unique position to help patients lose weight and make other healthy lifestyle changes. The American Society of Clinical Oncology is committed to reducing the impact of obesity on cancer and has established a multipronged initiative to accomplish this goal by 1) increasing education and awareness of the evidence linking obesity and cancer; 2) providing tools and resources to help oncology providers address obesity with their patients; 3) building and fostering a robust research agenda to better understand the pathophysiology of energy balance alterations, evaluate the impact of behavior change on cancer outcomes, and determine the best methods to help cancer survivors make effective and useful changes in lifestyle behaviors; and 4) advocating for policy and systems change to address societal factors contributing to obesity and improve access to weight management services for patients with cancer.

    Background Retrospective analysis of outcomes of R0 (negative margin) versus R1 (positive margin) liver resections for colorectal metastases (CLM) in the context of peri-operative chemotherapy. Methods All CLM resections between 2000 and 2006 were reviewed. Exclusion criteria included: macroscopically incomplete (R2) resections, the use of local treatment modalities, the presence of extra-hepatic disease and no peri-operative chemotherapy. R0/R1 status was based on pathological examination. Results Of 86 eligible patients, 63 (73%) had R0 and 23 (27%) had R1 resections. The two groups were comparable for the number, size of metastases and type of hepatectomy. The R1 group had more bilobar CLM (52% versus 24%, P = 0.018). The median follow-up was 3.1 years. Five-year overall and disease-free survival were 54% and 21% for the R0 group and 49% and 22% for the R1 group (P = 0.55 and P = 0.39, respectively). An intra-hepatic recurrence was more frequent in the R1 group (52% versus 27%, P = 0.02) and occurred more frequently at the surgical margin (22% versus 3%, P = 0.01). Discussion R1 resections were associated with a higher risk of intra-hepatic and surgical margin recurrence but did not negatively impact survival suggesting that in the era of efficient chemotherapy, the risk of an R1 resection should not be considered as a contraindication to surgery.

    Quantitative imaging using CT, MRI, and PET modalities will play an increasingly important role in the design of oncology trials addressing molecularly targeted, personalized therapies. The advent of molecularly targeted therapies, exemplified by antiangiogenic drugs, creates new complexities in the assessment of response. The Quantitative Imaging Network (QIN) addresses the need for imaging modalities which can accurately and reproducibly measure not just change in tumor size, but changes in relevant metabolic parameters, modulation of relevant signaling pathways, drug delivery to tumor, and differentiation of apoptotic cell death from other changes in tumor volume. This article provides an overview of the applications of quantitative imaging to phase 0 through phase 3 oncology trials. We describe the use of a range of quantitative imaging modalities in specific tumor types including malignant gliomas, lung cancer, head and neck cancer, lymphoma, breast cancer, prostate cancer, and sarcoma. In the concluding section, we discuss potential constraints on clinical trials using quantitative imaging, including complexity of trial conduct, impact on subject recruitment, incremental costs, and institutional barriers. Strategies for overcoming these constraints are presented. PMID:22898682

    A state-of-the art approach to the debates on ethical issues is key in order to gain guidance on research practices involving sick children and adolescents, as well as to identify research avenues in which it might be worth cooperating, to generate better or supplementary evidence. Based on a systematic literature search using MEDLINE, we report the main ethical developments in paediatric oncology clinical trials from 2003-13. The present knowledge about normative and empirical ethical demands in this setting is quantified and summarised in a list of 46 issues. This list primarily aims to provide readers with a comprehensive account of the main decision nodes and professional attitudes that enable families to make a safe, competent, and satisfactory decision about their child's enrolment, or non-participation, in cancer clinical trials. Our systematic Review shows how important it is for professionals to engage in a constant reflection on optimum trial designs, on the effect of offering trial participation on key family dynamics, and on the ways to understand families' needs and values accurately. In view of present scientific developments, we further emphasise the need to enhance societal awareness about research in children and adolescents, to prevent so-called research fatigue in small populations due to multiple solicitations or inadequate legal demands, and to reassess longstanding ethical certainties in the strictest view of promoting sick children's interests. This systematic Review allows a series of questions to be drawn to guide and encourage collective and individual endeavours that should lead to constant improvements in our research practices in paediatric clinical oncology research.

    Despite increasing numbers of cancer survivors, non-oncology physicians report discomfort and little training regarding oncologic and survivorship care. This pilot study assesses medical student comfort with medical oncology, surgical oncology, radiation oncology, hospice/palliative medicine, and survivorship care. A survey was developed with input from specialists in various fields of oncologic care at a National Cancer Institute-designated comprehensive cancer center. The survey included respondent demographics, reports of experience with oncology, comfort ratings with oncologic care, and five clinical vignettes. Responses were yes/no, multiple choice, Likert scale, or free response. The survey was distributed via email to medical students (MS1-4) at two US medical schools. The 105 respondents were 34 MS1s (32 %), 15 MS2s and MD/PhDs (14 %), 26 MS3s (25 %), and 30 MS4s (29 %). Medical oncology, surgical oncology, and hospice/palliative medicine demonstrated a significant trend for increased comfort from MS1 to MS4, but radiation oncology and survivorship care did not. MS3s and MS4s reported the least experience with survivorship care and radiation oncology. In the clinical vignettes, students performed the worst on the long-term chemotherapy toxicity and hospice/palliative medicine questions. Medical students report learning about components of oncologic care, but lack overall comfort with oncologic care. Medical students also fail to develop an increased self-assessed level of comfort with radiation oncology and survivorship care. These pilot results support development of a formalized multidisciplinary medical school oncology curriculum at these two institutions. An expanded national survey is being developed to confirm these preliminary findings. PMID:26153490

    Chemotherapy-induced nausea and vomiting (CINV) is one of the most common and troubling side effects of treatment, and the side effect cancer patients tend to fear most. An improved understanding of the pathophysiology underlying CINV, together with a clear definition of the risk for nausea and vomiting associated with specific chemotherapeutic agents, has for allowed the development of specific and effective antiemetic regimens. Anti­emesis is most effective when used prophylactically, a principle shared among CINV management guidelines. Several antiemetic drug classes are available; among the most effective of these are serotonin (5HT₃) receptor antagonists, neurokinin 1 (NK₁) receptor antagonists, and steroids (primarily dexamethasone), although others are commonly used as well. When choosing an appropriate antiemetic regimen, clinicians should consider patient-specific factors such as sex and prior history of CINV, as well as treatment-specific factors such as the emetogenic potential of each chemotherapeutic agent. Using these factors, clinicians can follow the available algorithms included in guidelines from groups such as the National Comprehensive Cancer Network, the American Society of Clinical Oncology, and the Multinational Association for Supportive Care in Cancer. Ongoing and future clinical trials will be pivotal in helping to further delineate the optimal strategies to prevent and manage CINV in cancer patients. PMID:21370520

    Racial and ethnic diversity has historically been difficult to achieve in National Cancer Institute-sponsored clinical trials, even while as many as 80% of those trials have faced difficulty in meeting overall recruitment targets. In an attempt to address these issues, NRG Oncology recently convened a comprehensive workshop titled "Clinical Trials Enrollment: Challenges and Opportunities." Discussants at the workshop included representatives of the three legacy groups of the NRG (ie, Gynecologic Oncology Group, National Surgical Adjuvant Breast and Bowel Program, and Radiation Therapy Oncology Group), a minority-based community clinical oncology program, a large integrated health care system, the leadership of the National Cancer Institute, and a large patient advocacy group. This article summarizes the concepts discussed at the workshop, which included: needs assessments, infrastructural support, training of investigators and research staff, specific clinical trial recruitment strategies (both system and community based), and development and mentoring of young investigators. Many new, more specific tactics, including use of diverse cancer care settings, direct-to-consumer communication, and the need for centralized information technology such as the use of software to match trials to special populations, are presented. It was concluded that new, innovative trial designs and the realities of limited funding would require the adoption of effective and efficient recruiting strategies, specialized training, and stakeholder engagement. US clinical research programs must generate and embrace new ideas and pilot test novel recruitment strategies if they are to maintain their historic role as world leaders in cancer care innovation and delivery.

    Chemotherapy extravasation remains an accidental complication of chemotherapy administration and may result in serious damage to patients. We review in this article the clinical aspects of chemotherapy extravasation and latest advances in definitions, classification, prevention, management and guidelines. We review the grading of extravasation and tissue damage according to various chemotherapeutic drugs and present an update on treatment and new antidotes including dexrazoxane for anthracyclines extravasation. We highlight the importance of education and training of the oncology team for prevention and prompt pharmacological and non-pharmacological management and stress the availability of new antidotes like dexrazoxane wherever anthracyclines are being infused.

    According to recent epidemiological studies, malignant diseases represent the second cause of mortality worldwide and metastasis is the main cause of morbidity and mortality in most cancers. Even if the concept of "cancer stem cells" (CSCs) was anticipated by the genius of Rudolph Virchow, the father of modern pathology, more than 150 years ago, it is only in last few years that that scientists have begun to develop strategies aimed at inhibiting CSCs at a molecular level, the only way cancer can truly be attacked, by crossing the border between histology and molecular biology. The current concise review aims at emphasizing the main characteristics of tumor initiating cells, bridging the basic science to clinical hematology and oncology. PMID:24965388

    It is challenging for patients to receive a new diagnosis of a life-threatening ocular tumor when visiting an ocular oncology clinic for the first time. Audio recording of patient-physician interactions has been shown to be an effective memory aid and stress-reducing technique for patients with various types of nonophthalmic cancer. This study evaluated a protocol for digitally recording the initial conversation between the ocular oncologist and the patient. Twenty patients were enrolled in the study, and 13 patients (65%) returned the survey. All of the patients who returned the survey reported being "very satisfied" with the audio recording, indicating that patients with a newly diagnosed ocular tumor were highly satisfied with the audio recording of their conversations with the ocular oncologist. Although larger studies are needed to confirm this conclusion, the initial results are encouraging. PMID:26057768

    The use of targeted anti-cancer agents is increasing. It is common to utilize a multi-modal treatment approach towards solid tumors, often including surgical resection, and it has become apparent that some targeted agents can impair wound healing or cause an increased risk of perioperative complications. This article reviews targeted agents used in solid tumor oncology with an emphasis on clinically relevant details. Overall, the evidence of targeted agents causing surgical complications is limited. The greatest amount of evidence exists for bevacizumab causing perioperative complications, possibly due to its extended half-life. There are limited data for cetuximab, sorafenib and sunitinib and very little for other solid tumor targeted agents. Our findings suggest that there should be heightened pharmacovigilence around targeted agents with respect to perioperative complications and increased post-surgical support for patients to aid early detection of postoperative complications until definitive data become available.

    Home care (HC) is important for patients with cancer as performance status declines. Our study of 1224 patients at a Canadian cancer center examined the impact of an oncology palliative care clinic (OPCC) on HC referral. The HC referral frequency was calculated before and after the first OPCC consultation, in total and according to performance status (Palliative Performance Scale, PPS). Characteristics associated with HC referral were investigated. After the first OPCC consultation, there was an increase in HC referral from 39% (477 of 1224; 49% of those with PPS ≤60) to 69% (841 of 1224; 88% of those with PPS ≤60). Factors independently associated with HC referral were poor PPS (P < .001) and older age (P = .003). Thus OPCC involvement resulted in markedly increased HC referrals, particularly for older patients with poor performance status. PMID:22777408

Patients (43) undergoing adjuvant/palliative chemotherapy with 5-Fluorouracil/leucovorin + oxaliplatin (FOLFOX4) were split into two groups: the UT group received chemotherapy plus 300 mg of Uncaria tomentosa daily and the C group received only FOLFOX4 and served as a control. Blood samples were collected before each of the 6 cycles of chemotherapy, and hemograms, oxidative stress, enzymes antioxidants, immunologic parameters, and adverse events were analyzed. The use of 300 mg of Uncaria tomentosa daily during 6 cycles of FOLFOX4 did not change the analyzed parameters, and no toxic effects were observed. PMID:21869902

    The American Society of Clinical Oncology (ASCO) convened a subcommittee to develop recommendations on improving the evidence base for treating older adults with cancer in response to a critical need identified by the Institute of Medicine. Older adults experience the majority of cancer diagnoses and deaths and make up the majority of cancer survivors. Older adults are also the fastest growing segment of the US population. However, the evidence base for treating this population is sparse, because older adults are underrepresented in clinical trials, and trials designed specifically for older adults are rare. The result is that clinicians have less evidence on how to treat older adults, who represent the majority of patients with cancer. Clinicians and patients are forced to extrapolate from trials conducted in younger, healthier populations when developing treatment plans. This has created a dearth of knowledge regarding the risk of toxicity in the average older patient and about key end points of importance to older adults. ASCO makes five recommendations to improve evidence generation in this population: (1) Use clinical trials to improve the evidence base for treating older adults with cancer, (2) leverage research designs and infrastructure for generating evidence on older adults with cancer, (3) increase US Food and Drug Administration authority to incentivize and require research involving older adults with cancer, (4) increase clinicians' recruitment of older adults with cancer to clinical trials, and (5) use journal policies to improve researchers' reporting on the age distribution and health risk profiles of research participants.

    Certain chemotherapy drugs for breast cancer may induce cardiotoxicity and these patients should be echocardiographically monitored. The performance of a focused echocardiographic evaluation (echoscopy) at the patient's location by a non-cardiologist appears to be feasible. The aim of the present study was to assess the accuracy of echoscopy performed by medical oncologists in an outpatient clinic using hand-held echocardiography devices. The study cohort comprised consecutive unselected patients who attended an oncology outpatient clinic. Two medical oncologists attended a one-week training period, which included theoretical and practical teaching by an expert cardiologist. Every subject underwent two echo examinations. The first examination was performed by an oncologist using a hand-held echo device and the second was performed by a cardiologist using a ‘premium’ device. Out of the 101 enrolled patients, 32 were men (31.7%) and the mean age was 56.03±16.88 years. There was a good global agreement [intra-class correlation coefficient (ICC): 0.65 for left ventricular ejection fraction (LVEF)]. When the results were analyzed depending on the period of time when the echo studies were performed, a clear and short learning curve was observed: LVEF started at ICC=0.58 and increased to 0.66 and 0.77 in the second and third period, respectively. There were extremely few clinically significant differences and a learning curve was also evident. In conclusion, cardiac echoscopy performed by an oncologist with a hand-held device may lead to a similar clinical management as a study performed by an expert cardiologist with a ‘premium’ system in patients under chemotherapy following a short training period.

    Objectives Changes in cognitive function have been identified in and reported by many cancer survivors. These changes have the potential to impact patient quality of life and functional ability. This prospective longitudinal study was designed to quantify the incidence of change in cognitive function in newly diagnosed ovarian cancer patients throughout and following primary chemotherapy. Methods Eligible patients had newly diagnosed, untreated ovarian cancer and had planned to receive chemotherapy. Web-based and patient reported cognitive assessments and quality of life questionnaires were conducted prior to chemotherapy, prior to cycle four, after cycle six, and six months after completion of primary therapy. Results Two-hundred-thirty-one evaluable patients entered this study between May 2010 and October 2011. At the cycle 4 time point, 25.2% (55/218) of patients exhibited cognitive impairment in at least one domain. At the post-cycle 6 and 6-month follow up time points, 21.1% (44/208) and 17.8% (30/169) of patients, respectively, demonstrated impairment in at least one domain of cognitive function. There were statistically significant, but clinically small, improvements in processing speed (p < 0.001) and attention (p < 0.001) but not in motor response time (p = 0.066), from baseline through the six-month follow up time period. Conclusions This was a large, prospective study designed to measure cognitive function in ovarian cancer. A subset of patients had evidence of cognitive decline from baseline during chemotherapy treatment in this study as measured by the web-based assessment; however, changes were generally limited to no more than one domain.

    Background The randomized controlled Pediatric Oncology Group study 9233 tested the hypothesis that dose-intensive (DI) chemotherapy would improve event-free survival (EFS) for children <3 years of age with newly diagnosed malignant brain tumors. Methods Of 328 enrolled eligible patients, diagnoses were medulloblastoma (n = 112), ependymoma (n = 82), supratentorial primitive neuroectodermal tumor (sPNET, n = 38) and other malignant brain tumors (n = 96), and were randomized to 72 weeks of standard dose chemotherapy (Regimen A, n = 162) or DI chemotherapy (Regimen B, n = 166). Radiation therapy (RT) was recommended for patients with evidence of disease at completion of chemotherapy or who relapsed within 6 months of chemotherapy completion. Results Distributions of EFS for Regimens A and B were not significantly different (P = 0.32) with 2- and 10-year rates of 22.8% ± 3.3% and 15.4% ± 3.7%, and 27.1% ± 3.4% and 20.8% ± 3.8%, respectively. Thus, the study hypothesis was rejected. While distributions of EFS and OS were not significantly different between Regimens A and B for patients with medulloblastoma and sPNET, DI chemotherapy resulted in significantly improved EFS distribution (P = .0011) (2-year EFS rates of 42.1% vs. 19.6% with SD chemotherapy), but not OS distribution, for patients with centrally confirmed ependymoma. The degree of surgical resection affected EFS, OS or both for most tumor groups. Approximately 20%, 40% and 20% of patients with medulloblastoma, ependymoma treated with DI chemotherapy, and sPNET, respectively appear to have been cured without RT. Of 11 toxic deaths on study, 10 occurred on the DI chemotherapy arm. Conclusions Prolonged dose-intensive chemotherapy given to infants with malignant brain tumors resulted in increased EFS only for patients with ependymoma. PMID:24335695

    Objective To explore the value of multiple clinical endpoints in the unique setting of ovarian cancer. Methods A clinical trial workgroup was established by the Society of Gynecologic Oncology to develop a consensus statement via multiple conference calls, meetings and white paper drafts. Results Clinical trial endpoints have profound effects on late phase clinical trial design, result interpretation, drug development, and regulatory approval of therapeutics. Selection of the optimal clinical trial endpoint is particularly provocative in ovarian cancer where long overall survival (OS) is observed. The lack of new regulatory approvals and the lack of harmony between regulatory bodies globally for ovarian cancer therapeutics are of concern. The advantages and disadvantages of the numerous endpoints available are herein discussed within the unique context of ovarian cancer where both crossover and post-progression therapies potentially uncouple surrogacy between progression-free survival (PFS) and OS, the two most widely supported and utilized endpoints. The roles of patient reported outcomes (PRO) and health related quality of life (HRQoL) are discussed, but even these widely supported parameters are affected by the unique characteristics of ovarian cancer where a significant percentage of patients may be asymptomatic. Original data regarding the endpoint preferences of ovarian cancer advocates is presented. Conclusions Endpoint selection in ovarian cancer clinical trials should reflect the impact on disease burden and unique characteristics of the treatment cohort while reflecting true patient benefit. Both OS and PFS have led to regulatory approvals and are clinically important. OS remains the most objective and accepted endpoint because it is least vulnerable to bias; however, the feasibility of OS in ovarian cancer is compromised by the requirement for large trial size, prolonged time-line for final analysis, and potential for unintended loss of treatment effect

    OBJECTIVE. An ecological framework is proposed for assessing factors important to consider in allocating funds to promote sound performance of interorganizational programs. DATA SOURCE/STUDY SETTING. This framework is used to examine the first generation of Community Clinical Oncology Programs (CCOPs) funded by the National Cancer Institute (NCI) from 1983-1986 to coordinate clinical research activity at the local level. The research reported is based on secondary data collected for the Community Cancer Care Evaluation at the Fred Hutchinson Cancer Center. STUDY DESIGN. A repeated measures design was used to analyze differences in the level and patterns of CCOP productivity, a measure of the number of patients enrolled on NCI-approved Phase III trials. The predictive dimensions include (1) measures of environmental inputs (population density, organizational dominance, professional support, NCI funding); (2) measures of organizational inputs (number of hospitals, number of staff, number of physicians, NCI experience, clinical research experience); and (3) structural measures (functional specialization, administrative concentration). Predicted relationships were assessed using general linear models procedures. DATA COLLECTION/EXTRACTION METHODS. Data obtained from NCI files were supplemented by interviews with NCI personnel and published statistics. PRINCIPAL FINDINGS. Funding level, clinical research experience, and number of staff are the most important predictors of patient enrollment. Clinical research experience has a positive relationship with patient enrollment and a negative association with changes in enrollment. The reversal is explained by the influence of the CCOPs that had the greatest amount of clinical research experience at the beginning of the program. CONCLUSIONS. The ecological approach provides a useful framework for understanding factors that should be considered in funding interorganizational programs and promoting their development. Most

    We conducted a preliminarily study on the clinical characteristics of chronic lung injury (CLI) in patients with non-Hodgkin lymphoma (NHL) after CHOP chemotherapy and observed the effects of this injury on CHOP treatment efficacy. Sixty patients who were diagnosed as NHL and received CHOP chemotherapy in hospital were enrolled for this clinical trial. CLI was assessed by clinical symptoms and computed tomography (CT) scan conducted before and after chemotherapy. The effect of CLI on the efficacy of CHOP chemotherapy in patients with NHL was evaluated by comparing treatment response and recurrence rate to patients with no signs of lung injury. Our CT scans revealed multiple signs of CLI in 35 patients (56.67 %), such as pulmonary diffuse, limited infiltration shadow or ground glass-like changes. Among them, 23 patients (38.33 %) showed bilateral diffuse lung injury and 12 (20.00 %) showed topical lung injury. Most patients suffering from 6 to 12 months delayed recurrence exhibited signs of CLI. The inflammatory response of CLI may increase the risk of disease progression and recurrence. Therefore, early diagnosis and intervention, which play a positive role in the clinical treatment and the long-term efficacy, are critical for patients with NHL. PMID:25201066

    Tailoring medical treatment to individual patients requires a strong foundation in research to provide the data necessary to understand the relationship between the disease, the patient, and the type of treatment advocated for. Non-therapeutic oncology clinical trials studying therapeutic resistance require the participation of patients, yet only a small percentage enroll. Treating physicians are often relied on to recruit patients, but they have a number of ethical obligations that might be perceived as barriers to recruiting. Concepts such as voluntariness of consent and conflicts of interest can have an impact on whether physicians will discuss clinical trials with their patients and how patients perceive the information. However, these ethical obligations should not be prohibitive to physician recruitment of patients – precautions can be taken to ensure that patients’ consent to research participation is fully voluntary and devoid of conflict, such as the use of other members of the research team than the treating physician to discuss the trial and obtain consent, and better communication between researchers, clinicians, and patients. These can ensure that research benefits are maximized for the good of patients and society. PMID:23483771

    The efficacy of PD-1/PD-L1 targeted therapies in addition to anti-CTLA-4 solidifies immunotherapy as a modality to add to the anticancer arsenal. Despite raising the bar of clinical efficacy, immunologically targeted agents raise new challenges to conventional drug development paradigms by highlighting the limited relevance of assessing standard pharmacokinetics (PK) and pharmacodynamics (PD). Specifically, systemic and intratumoral immune effects have not consistently correlated with standard relationships between systemic dose, toxicity, and efficacy for cytotoxic therapies. Hence, PK and PD paradigms remain inadequate to guide the selection of doses and schedules, both starting and recommended Phase 2 for immunotherapies. The promise of harnessing the immune response against cancer must also be considered in light of unique and potentially serious toxicities. Refining immune endpoints to better inform clinical trial design represents a high priority challenge. The Cancer Immunotherapy Trials Network investigators review the immunodynamic effects of specific classes of immunotherapeutic agents to focus immune assessment modalities and sites, both systemic and importantly intratumoral, which are critical to the success of the rapidly growing field of immuno-oncology.

    Imatinib mesylate is a competitive inhibitor of BCR/ ABL tyrosine kinase and inhibits also several receptor tyrosin kinases. Since its launch to the market, imatinib has proven to be very valuable in the treatment of Philadelphia chromosome (BCR/ ABL) -  positive (Ph+) chronic myeloid leukemia and Kit (CD117) positive gastrointestinal stromal tumors. The drug is metabolized by cytochrome P450, and there are many clinically important pharmacokinetic drug-drug interactions described in the literature. Frequent polypharmacy in oncological patients increases probability of such interactions, and also adherence may play its role during longterm treatment. Fixed dosing therapeutic regimens fail to respect known interindividual variability in pharmacokinetics of the drug and thus, some patients may not achieve sufficient plasma concentrations. Based on current evidence, there seems to be a relationship between plasma concentration and clinical response to imatinib. Therefore, imatinib appears to be suitable candidate for therapeutic drug monitoring. Here, we present an overview of pharmacokinetics, drug-drug interactions and current knowledge and suggestions on therapeutic drug monitor-ing of imatinib, its potential benefits and limitations.

    High quality clinical research is essential for advancing knowledge in the areas of veterinary radiology and radiation oncology. Types of clinical research studies may include experimental studies, method-comparison studies, and patient-based studies. Experimental studies explore issues relative to pathophysiology, patient safety, and treatment efficacy. Method-comparison studies evaluate agreement between techniques or between observers. Patient-based studies investigate naturally acquired disease and focus on questions asked in clinical practice that relate to individuals or populations (e.g., risk, accuracy, or prognosis). Careful preplanning and study design are essential in order to achieve valid results. A key point to planning studies is ensuring that the design is tailored to the study objectives. Good design includes a comprehensive literature review, asking suitable questions, selecting the proper sample population, collecting the appropriate data, performing the correct statistical analyses, and drawing conclusions supported by the available evidence. Most study designs are classified by whether they are experimental or observational, longitudinal or cross-sectional, and prospective or retrospective. Additional features (e.g., controlled, randomized, or blinded) may be described that address bias. Two related challenging aspects of study design are defining an important research question and selecting an appropriate sample population. The sample population should represent the target population as much as possible. Furthermore, when comparing groups, it is important that the groups are as alike to each other as possible except for the variables of interest. Medical images are well suited for clinical research because imaging signs are categorical or numerical variables that might be predictors or outcomes of diseases or treatments. PMID:23578318

    In response to the evolution of the information-seeking behaviour of patients and concerns from health professionals regarding cancer patient information, the French National Federation of Comprehensive Cancer Centres (FNCLCC) introduced, in 1998, an information and education program dedicated to patients and relatives, the SOR SAVOIR PATIENT program (SSP). The methodology of this program adheres to established quality criteria regarding the elaboration of patient information. Cancer patient information, developed in this program, is based on clinical practice guidelines produced by the FNCLCC and the twenty French regional cancer centres, the National League against Cancer, the French Hospital Federation, the National Oncology Federation of Regional and University Hospitals, the French Oncology Federation of General Hospitals, many learned societies, as well as an active participation of patients, former patients and caregivers. The guidelines, "Standards, Options: Recommendations" (SOR) are used as primary information sources. The handbook SOR SAVOIR PATIENT Understanding positron emission tomography (PET) with [18F]-FDG in clinical oncology, integrally published in this issue of the Bulletin du Cancer, is an adapted version of the clinical practice guidelines (CPG) Standards, Options and Recommendations for positron emission tomography (PET) with [18F]-FDG in clinical oncology. The main objectives of this article are to allow persons affected by cancer and their close relatives to better understand this medical imaging technique and its implementation. This document also offers health professionals a synthetic evidence-based patient information source that should help them communicate that information during the physician-patient encounter. Positron emission tomography (PET) is a scintigraphy technique using a radiotracer, [18F]-fluorodeoxyglucose (abbreviated [18F]-FDG), administered intravenously into the patient's arm.

    Aims: Aim of this study was to monitor the environment at the Transplant Unit—Hemato-Oncology Clinic, University Hospital Olomouc (Olomouc, Czech Republic) and identify risks for the patients. Methods and Results: Microorganisms were cultivated under standard aerobic conditions. Strains were biochemically identified using the BD Phoenix™ PID Panel (USA). Legionella pneumophila was identified by DNA sequencing. From the air, the most frequently isolated strains were coagulase-negative staphylococci (94.3%), Micrococcus spp. and Bacillus spp. No Gram-negative strains were isolated from the air. From the surfaces, the most frequently isolated Gram-positive strains were coagulase-negative staphylococci (67.4%), Bacillus spp., enterococci (5.5%), Staphylococcus aureus (2.3%) and Micrococcus spp. (1.7%). From the surfaces, the most frequently isolated Gram-negative strains were from genera Pseudomonas (28%), Enterobacter (28%), E. coli (6%), and Klebsiella spp. (5%). From the personnel, the most frequently isolated Gram-positive strains were coagulase-negative staphylococci (59.6%), Bacillus spp. (24.1%) and Staphylococcus aureus (9.8%). From the personnel, the most frequently isolated Gram-negative strains were Enterobacter spp. (61%), Klebsiella oxytoca (18%), and E. coli (11%). Microscopic filamentous fungi were isolated in 13 cases (2.71%). Isolated strains were Aspergillus spp. (4), Trichoderma spp. (2), Penicillium spp. (2), one case of the strains Paecilomyces spp., Eurotium spp., Monilia spp. Conclusions: The study found no significant deviations in the microbial contamination of the cleanroom air.

    Soft tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin that display a heterogenous mix of clinical and pathologic characteristics. STS can develop from fat, muscle, nerves, blood vessels, and other connective tissues. The evaluation and treatment of patients with STS requires a multidisciplinary team with demonstrated expertise in the management of these tumors. The complete NCCN Guidelines for Soft Tissue Sarcoma (available at NCCN.org) provide recommendations for the diagnosis, evaluation, and treatment of extremity/superficial trunk/head and neck STS, as well as intra-abdominal/retroperitoneal STS, gastrointestinal stromal tumor, desmoid tumors, and rhabdomyosarcoma. This manuscript discusses guiding principles for the diagnosis and staging of STS and evidence for treatment modalities that include surgery, radiation, chemoradiation, chemotherapy, and targeted therapy.

    Purpose: Radiation Therapy Oncology Group 9402 compared procarbazine, lomustine, and vincristine (PCV) chemotherapy plus radiation therapy (PCV + RT) vs. RT alone for anaplastic oligodendroglioma. Here we report longitudinal changes in cognition and quality of life, effects of patient factors and treatments on cognition, quality of life and survival, and prognostic implications of cognition and quality of life. Methods and Materials: Cognition was assessed by Mini Mental Status Examination (MMSE) and quality of life by Brain-Quality of Life (B-QOL). Scores were analyzed for survivors and within 5 years of death. Shared parameter models evaluated MMSE/B-QOL with survival. Results: For survivors, MMSE and B-QOL scores were similar longitudinally and between treatments. For those who died, MMSE scores remained stable initially, whereas B-QOL slowly declined; both declined rapidly in the last year of life and similarly between arms. In the aggregate, scores decreased over time (p = 0.0413 for MMSE; p = 0.0016 for B-QOL) and were superior with age <50 years (p < 0.001 for MMSE; p = 0.0554 for B-QOL) and Karnofsky Performance Score (KPS) 80-100 (p < 0.001). Younger age and higher KPS were associated with longer survival. After adjusting for patient factors and drop-out, survival was longer after PCV + RT (HR = 0.66, 95% CI = 0.49-0.9, p = 0.0084; HR = 0.74, 95% CI = 0.54-1.01, p = 0.0592) in models with MMSE and B-QOL. In addition, there were no differences in MMSE and B-QOL scores between arms (p = 0.4752 and p = 0.2767, respectively); higher scores predicted longer survival. Conclusion: MMSE and B-QOL scores held steady in the upper range in both arms for survivors. Younger, fitter patients had better MMSE and B-QOL and longer survival.

    A message from ASCO'S President. It has been forty years since President Richard Nixon signed the National Cancer Act of 1971, which many view as the nation's declaration of the "War on Cancer." The bill has led to major investments in cancer research and significant increases in cancer survival. Today, two-thirds of patients survive at least five years after being diagnosed with cancer compared with just half of all diagnosed patients surviving five years after diagnosis in 1975. The research advances detailed in this year's Clinical Cancer Advances demonstrate that improvements in cancer screening, treatment, and prevention save and improve lives. But although much progress has been made, cancer remains one of the world's most serious health problems. In the United States, the disease is expected to become the nation's leading cause of death in the years ahead as our population ages. I believe we can accelerate the pace of progress, provided that everyone involved in cancer care works together to achieve this goal. It is this viewpoint that has shaped the theme for my presidential term: Collaborating to Conquer Cancer. In practice, this means that physicians and researchers must learn from every patient's experience, ensure greater collaboration between members of a patient's medical team, and involve more patients in the search for cures through clinical trials. Cancer advocates, insurers, and government agencies also have important roles to play. Today, we have an incredible opportunity to improve the quality of cancer care by drawing lessons from the real-world experiences of patients. The American Society of Clinical Oncology (ASCO) is taking the lead in this area, in part through innovative use of health information technology. In addition to our existing quality initiatives, ASCO is working with partners to develop a comprehensive rapid-learning system for cancer care. When complete, this system will provide physicians with personalized, real

    Neoadjuvant chemotherapy has more and more become clinical routine during the past years. Results from large randomized trials like NSABP-B18 show that survival parameters are not affected if sequence of therapy is changed. Survival parameters have been intensively studied, but surgical standards after primary chemotherapy are much less well defined. Results from the early trials comparing lumpectomy or quadrantectomy with mastectomy are generally transposed to the neoadjuvant situation. In this context the "result of downstaging" is surgically treated like otherwise the primary tumor would have been treated. Though local recurrence rates reported after primary chemotherapy are not increased within the whole population this may not be correct for subgroups. E.g. within the NSABP-B18 trial significantly higher local recurrence rates are reported for those patients who initially were proposed to have mastectomy and who actually received lumpectomy after effective primary chemotherapy. Another unresolved problem is surgery after complete remission, which as histopathology demonstrates corresponds often not to pathological complete remission. Therefore in most cases the initially involved area is resected, which may result in a more radical surgical approach to complete remission than to partial remission. Further standardisation of surgical approach to patients after neoadjuvant chemotherapy should be evaluated within phase III trials. PMID:10857211

    Purpose: Long-term (LT) androgen suppression (AS) with radiation therapy (RT) is a standard treatment of high-risk, localized prostate cancer (PCa). Radiation Therapy Oncology Group 9902 was a randomized trial testing the hypothesis that adjuvant combination chemotherapy (CT) with paclitaxel, estramustine, and oral etoposide plus LT AS plus RT would improve overall survival (OS). Methods and Materials: Patients with high-risk PCa (prostate-specific antigen 20-100 ng/mL and Gleason score [GS] ≥7 or clinical stage ≥T2 and GS ≥8) were randomized to RT and AS (AS + RT) alone or with adjuvant CT (AS + RT + CT). CT was given as four 21-day cycles, delivered beginning 28 days after 70.2 Gy of RT. AS was given as luteinizing hormone-releasing hormone for 24 months, beginning 2 months before RT plus an oral antiandrogen for 4 months before and during RT. The study was designed based on a 6% improvement in OS from 79% to 85% at 5 years, with 90% power and a 2-sided alpha of 0.05. Results: A total of 397 patients (380 eligible) were randomized. The patients had high-risk PCa, 68% with GS 8 to 10 and 34% T3 to T4 tumors, and median prostate-specific antigen of 22.6 ng/mL. The median follow-up period was 9.2 years. The trial closed early because of excess thromboembolic toxicity in the CT arm. The 10-year results for all randomized patients revealed no significant difference between the AS + RT and AS + RT + CT arms in OS (65% vs 63%; P=.81), biochemical failure (58% vs 54%; P=.82), local progression (11% vs 7%; P=.09), distant metastases (16% vs 14%; P=.42), or disease-free survival (22% vs 26%; P=.61). Conclusions: NRG Oncology RTOG 9902 showed no significant differences in OS, biochemical failure, local progression, distant metastases, or disease-free survival with the addition of adjuvant CT to LT AS + RT. The trial results provide valuable data regarding the natural history of high-risk PCa treated with LT AS + RT and have implications for

    There is a drive in the UK to revise chemotherapy provision for people living in rural communities. Using a different model of treatment delivery might impact positively upon the experience of receiving chemotherapy. In 2007 the first nurse-led mobile chemotherapy unit (MCU) in the UK was launched in the South West of England with the intention of providing treatment closer to home. The aim of the research was to explore experiences of people with cancer who received chemotherapy treatment in outpatient clinic and/or onboard the MCU using an interpretive phenomenological approach. Interviews were conducted with 20 people and data were interpreted using thematic analysis. The cancer and chemotherapy journey was described as being undertaken by the participant and their significant other. Available car parking and travelling impacted upon quality of life, as did the environment and accessibility of nurses to discuss issues with participants. The most important, distinguishing feature between receiving chemotherapy in outpatient clinic and the MCU was the amount of time spent waiting. Having treatment on the MCU was perceived to be less formal and therefore less stressful. Participants reported significant savings in time spent travelling, waiting and having treatment, expenditure on fuel and companion costs. PMID:23611562

    2003-06-15

    As the leading organization representing cancer specialists involved in patient care and clinical research, the American Society of Clinical Oncology (ASCO) reaffirms its commitment to integrating cancer risk assessment and management, including molecular analysis of cancer predisposition genes, into the practice of oncology and preventive medicine. The primary goal of this effort is to foster expanded access to, and continued advances in, medical care provided to patients and families affected by hereditary cancer syndromes. The 1996 ASCO Statement on Genetic Testing for Cancer Susceptibility set forth specific recommendations relating to clinical practice, research needs, educational opportunities, requirement for informed consent, indications for genetic testing, regulation of laboratories, and protection from discrimination, as well as access to and reimbursement for cancer genetics services. In updating this Statement, ASCO endorses the following principles: Indications for Genetic Testing: ASCO recommends that genetic testing be offered when 1) the individual has personal or family history features suggestive of a genetic cancer susceptibility condition, 2) the test can be adequately interpreted, and 3) the results will aid in diagnosis or influence the medical or surgical management of the patient or family members at hereditary risk of cancer. ASCO recommends that genetic testing only be done in the setting of pre- and post-test counseling, which should include discussion of possible risks and benefits of cancer early detection and prevention modalities. Special Issues in Testing Children for Cancer Susceptibility: ASCO recommends that the decision to offer testing to potentially affected children should take into account the availability of evidence-based risk-reduction strategies and the probability of developing a malignancy during childhood. Where risk-reduction strategies are available or cancer predominantly develops in childhood, ASCO believes that

TCS-47 for diagnostic radiology (2010) and TCS-50 for nuclear medicine (2011) were also involved in the syllabus. These training courses had been developed by IAEA RCA RAS6038 project since 2002. In this paper, first, comparison with other training programs in the world was made in terms of (1) Degree of extent of subject or field, (2) Concreteness or specificity, (3) Degree of completion, (4) Method of certification and (5) Practicability. IAEA TCS series got the most points among ten programs such as EMERALD/EMIT, AAPM rpt.No.90 and CAMPEP accredited programs. Second, TCS-37, TCS47 and TCS50 were broken down to 6, 5 and 6 subjects of training course respectively. Third, each subject was further broken down to 15 times of training schedule where every time was composed by 3 hours of training. Totally 45 hours of a subject were assigned to one semester for getting one unit of credit. Seventeen units should be credited up to three years in graduate course to finish the whole program.

    2014-01-01

    Metabolomics research has the potential to provide biomarkers for the detection of disease, for subtyping complex disease populations, for monitoring disease progression and therapy, and for defining new molecular targets for therapeutic intervention. These potentials are far from being realized because of a number of technical, conceptual, financial, and bioinformatics issues. Mass spectrometry provides analytical platforms that address the technical barriers to success in metabolomics research; however, the limited commercial availability of analytical and stable isotope standards has created a bottleneck for the absolute quantitation of a number of metabolites. Conceptual and financial factors contribute to the generation of statistically under-powered clinical studies, whereas bioinformatics issues result in the publication of a large number of unidentified metabolites. The path forward in this field involves targeted metabolomics analyses of large control and patient populations to define both the normal range of a defined metabolite and the potential heterogeneity (eg, bimodal) in complex patient populations. This approach requires that metabolomics research groups, in addition to developing a number of analytical platforms, build sufficient chemistry resources to supply the analytical standards required for absolute metabolite quantitation. Examples of metabolomics evaluations of sulfur amino-acid metabolism in psychiatry, neurology, and neuro-oncology and of lipidomics in neurology will be reviewed. PMID:23842599

    Nurses today work in practice settings where the expectation is to "draw upon the best evidence to provide the care most appropriate to each patient" (Olsen, Goolsby, & McGinnis, 2009, p. 10) while caring for patients with high acuity in highly specialized settings. Within the nursing profession, the Magnet Recognition Program® advocates for exemplary professional practice and the generation of new knowledge through research and clinical innovation. Nurses working in a clinical setting are often the best resource to identify important clinical questions and gaps in practice, but a lack of resources presents challenges to nurses in fully developing their questions and identifying the most appropriate methods to answer them. These challenges often fall into three broad categories: individual nurse characteristics, organizational characteristics, and environmental characteristics (Dobbins, Ciliska, Cockerill, Barnsley, & DiCenso, 2002). Creating a dedicated partnership between nurses and library staff is one method that can overcome these challenges to use existing resources and support nurses who are asking and answering important clinical questions (DePalma, 2005; Vrabel, 2005).

    Background The translation of research evidence into practice is facilitated by clinical trials such as those sponsored by the National Cancer Institute’s Community Clinical Oncology Program (CCOP) that help disseminate cancer care innovations to community-based physicians and provider organizations. However, CCOP participation involves unsubsidized costs and organizational challenges that raise concerns about sustained provider participation in clinical trials. Objectives This study was designed to improve our understanding of why providers participate in the CCOP in order to inform the decision-making process of administrators, clinicians, organizations, and policy-makers considering CCOP participation. Research Methods We conducted a multi-site qualitative study of five provider organizations engaged with the CCOP. We interviewed 41 administrative and clinician key informants, asking about what motivated CCOP participation, and what benefits they associated with involvement. We deductively and inductively analyzed verbatim interview transcripts, and explored themes that emerged. Results Interviewees expressed both “altruistic” and “self-interested” motives for CCOP participation. Altruistic reasons included a desire to increase access to clinical trials and feeling an obligation to patients. Self-interested reasons included the desire to enhance reputation, and a need to integrate disparate cancer care activities. Perceived benefits largely matched expressed motives for CCOP participation, and included internal and external benefits to the organization, and quality of care benefits for both patients and participating physicians. Conclusion The motives and benefits providers attributed to CCOP participation are consistent with translational research goals, offering evidence that participation can contribute value to providers by expanding access to innovative medical care for patients in need.

    This is a preliminary report on the Radiation Therapy Oncology Group (RTOG) pilot study 77-08, of a combination of chemotherapy with vincristine-bleomycin-methotrexate, followed by radiotherapy, for inoperable carcinomas of the head and neck. The main objectives of the study were to determine toxicity and tumor control. Patients who were included had untreated carcinomas, with no distant metastases, and with adequate pulmonary, renal, and liver function. Forty patients were registered for the study. Chemotherapy started with vincristine--1.5 mgs/m/sup 2/ (maximum of 2 mgs) by I.V. injection, followed by bleomycin drip for 48 hours (15 units/day), and then methotrexate (200 mgs/m/sup 2/ divided in equal doses 6 hours apart) with folinic acid rescue. Eleven patients received one course of the stated chemotherapy; 28 were given two courses with one week rest period between them. Radical curative radiotherapy was started usually two weeks after chemotherapy. A surgical procedure was considered if the patient was found operable after receiving a dose of 5000 rad with continuous therapy or at 3000 rad with split-course therapy. The level of toxicity that resulted from this combined therapy was considered acceptable. The percentage of complete response of the primary tumor was 6% with chemotherapy; this increased to 46% after irradiation, and to 65% when surgery was added.

    In order to determine the clinical efficacy and adverse reactions of chemotherapy and verapamil infusion through a target artery to treat colorectal cancer patients with metastasis after failure with previous conventional treatments. Patients with metastatic colon cancer (n = 36) received an infusion of verapamil, interleukin-2, oxaliplatin (or hydroxy camptothecin or irinotecan hydrochloride), fluorouracil and calcium folinate through target artery using the Seldinger puncture technique. From the second day of infusion, the patients were treated with fluorouracil and calcium folinate via systematic intravenous injection for 2-3 days. Efficacy was evaluated after at least two treatment courses. The objective response including complete or partial response was 58.3% in the 36 patients; clinical benefit rate, evaluated by Karnofsky Performance Status score was 91.7%; by weight was 83.3%; by the amount of painkiller consumed was 80.6%. No patient experienced side effects associated with heart function. Post-treatment, the P-R period, Q-T period, QRS, and heart rate were not significantly different than before treatment. Liver function was significantly improved. Side effects of chemotherapy were minor in comparison to those observed with intravenous chemotherapy. Infusion of verapamil and chemotherapy directly into pelvic tumor tissue can increase treatment efficacy and has been shown to be a relatively safe technique. PMID:21562945

    EXECUTIVE SUMMARY Successful participation in the National Cancer Institute’s (NCI) Community Clinical Oncology Program (CCOP) can expand access to clinical trials and promote cancer treatment innovations for patients and communities otherwise removed from major cancer centers. Yet CCOP participation involves administrative, financial, and organizational challenges that can impact hospital and provider participants. This study was designed to improve our understanding of challenges associated with CCOP participation from the perspectives of involved providers, and to learn about opportunities to overcome these challenges. We conducted five case studies of hospitals and providers engaged with the CCOP. Across organizations we interviewed forty-one administrative, physician, and nurse key informants. We asked about CCOP participation, focusing on issues related to implementation, operations, and organizational support. We analyzed interview transcripts both deductively and inductively, exploring themes that emerged. Interviewees noted seven challenges associated with CCOP participation: 1) lack of appreciation for the value of participation; 2) poor understanding about CCOP operations; 3) cost; 4) need to meet CCOP requirements; 5) required workflow changes; 6) managing patient recruitment and physician involvement; and 7) sustaining hospital leadership support. Informants also suggested three major opportunities to facilitate participation: 1) increase awareness of the CCOP; 2) enhance commitment to the CCOP; and 3) promote and support champions of the CCOP. Improving our understanding of the challenges and facilitators of CCOP participation may help hospitals and providers in efforts to increase and sustain participation in the CCOP, thus helping to helping to preserve access to innovative medical treatment options for patients in need.

    Precision medicine (PM) requires the delivery of individually adapted medical care based on the genetic characteristics of each patient and his/her tumor. The last decade witnessed the development of high-throughput technologies such as microarrays and next-generation sequencing which paved the way to PM in the field of oncology. While the cost of these technologies decreases, we are facing an exponential increase in the amount of data produced. Our ability to use this information in daily practice relies strongly on the availability of an efficient bioinformatics system that assists in the translation of knowledge from the bench towards molecular targeting and diagnosis. Clinical trials and routine diagnoses constitute different approaches, both requiring a strong bioinformatics environment capable of (i) warranting the integration and the traceability of data, (ii) ensuring the correct processing and analyses of genomic data, and (iii) applying well-defined and reproducible procedures for workflow management and decision-making. To address the issues, a seamless information system was developed at Institut Curie which facilitates the data integration and tracks in real-time the processing of individual samples. Moreover, computational pipelines were developed to identify reliably genomic alterations and mutations from the molecular profiles of each patient. After a rigorous quality control, a meaningful report is delivered to the clinicians and biologists for the therapeutic decision. The complete bioinformatics environment and the key points of its implementation are presented in the context of the SHIVA clinical trial, a multicentric randomized phase II trial comparing targeted therapy based on tumor molecular profiling versus conventional therapy in patients with refractory cancer. The numerous challenges faced in practice during the setting up and the conduct of this trial are discussed as an illustration of PM application. PMID:24910641

    Although the prognosis of childhood cancers has dramatically improved over the last three decades, new active drugs are needed. Camptothecins represent a very attractive new class of anticancer drugs to develop in paediatric oncology. The preclinical and clinical development of two of these DNA-topoisomerase I inhibitors, i.e. topotecan and irinotecan, is ongoing in paediatric malignancies. Here we review the currently available results of this evaluation. Topotecan proved to be active against several paediatric tumour xenografts. In paediatric phase I studies exploring several administration schedules, myelosuppression was dose-limiting. The preliminary results of topotecan evaluation in phase II study showed antitumour activity in neuroblastoma (response rate: 15% at relapse and 37% in newly diagnosed patients with disseminated disease) and in metastatic rhabdomyosarcoma (40% in untreated patients). Topotecan-containing drug combinations are currently investigated. Irinotecan displayed a broad spectrum of activity in paediatric solid tumour xenografts, including rhabdo-myosarcoma, neuroblastoma, peripheral primitive neuroectodermal tumour, medulloblastoma, ependymoma, malignant glioma and juvenile colon cancer. For several of these histology types, tumour-free survivors have been observed among animals bearing an advanced-stage tumour at time of treatment. The clinical evaluation of irinotecan in children is ongoing. Irinotecan undergoes a complex in vivo biotransformation involving several enzyme systems, such as carboxylesterase, UDPGT and cytochrome P450, in children as well as in adults. Preclinical studies of both drugs have shown that their activity was schedule-dependent. The optimal schedule of administration is an issue that needs to be addressed in children. In conclusion, the preliminary results of the paediatric evaluation of camptothecin derivatives show very encouraging results in childhood malignancies. The potential place of camptothecins in the

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, p<0.05). For the aggregate of all cancers, the under-treatment rate significantly declined (p = 0.008) from 4% to 0% after the introduction of case rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations. PMID:26870963

    Conventional oral and intravenous chemotherapies permeate throughout the body, exposing healthy tissues to similar cytotoxic drug levels as tumors. This leads to significant dose-limiting toxicities that may prevent patients from receiving sufficient treatment to overcome cancers. Therefore, a number of locoregional drug-delivery strategies have been evaluated and implemented in preclinical studies, clinical trials and in practice, in the past decades to minimize systemic toxicities from chemotherapeutic agents and to improve treatment outcomes. Localized treatment is beneficial because many cancers, such as melanoma, peritoneal cancer and breast cancer, advance locally adjacent to the site of the primary tumors prior to their circulatory invasion. In this article, we will review the feasibility, safety and efficacy of multiple localized chemotherapies in clinical use and preclinical development. PMID:22229080

    Purpose. To review the literature and make recommendations for the use of anthracycline-based adjuvant chemotherapy in adult patients with soft tissue sarcoma (STS). Patients. The recommendations apply to patients >15 years old with completely resected STS. Methods. A systematic overview of the published literature was combined with a consensus process around the interpretation of the evidence in the context of conventional practice to develop an evidence-based practice guideline. Results. Four meta-analyses and 17 randomized clinical trials comparing anthracycline-based adjuvant chemotherapy versus observation were reviewed. The Sarcoma Meta-Analysis Collaboration (SMAC) was the best analysis because it assessed individual patient data and had the longest follow-up. The results of the SMAC meta-analysis together with data from more recently published randomized trials, as well as our analysis of the toxicity and compliance data, are incorporated in this systematic review. Discussion. It is reasonable to consider anthracycline-based adjuvant chemotherapy in patients who have had removal of a sarcoma with features predicting a high likelihood of relapse (deep location, size >5 cm, high histological grade). Although the benefits of adjuvant chemotherapy are most apparent in patients with extremity sarcomas, patients with high-risk tumours at other sites should also be considered for such therapy.

    Background There is an urgent need for a robust, clinically useful predictive model for survival in a heterogeneous group of patients with metastatic cancer referred to radiation oncology. Methods From May 2012 to August 2013, 143 consecutive patients with stage IV cancer were prospectively evaluated by a single radiation oncologist. We retrospectively analyzed the effect of 29 patient, laboratory and tumor-related prognostic factors on overall survival using univariate analysis. Variables that were statistically significant on univariate analysis were entered into a multivariable Cox regression to identify independent predictors of overall survival. Results The median overall survival was 5.5 months. Four prognostic factors significantly predicted survival on multivariable analysis including ECOG performance status (0–1 vs. 2 vs. 3–4), number of active tumors (1 to 5 vs. ≥6), albumin levels (≥3.4 vs. 2.4 to 3.3 vs. <2.4 and primary tumor site (Breast, Kidney or Prostate vs. Other). Risk group stratification was performed by assigning points for adverse prognostic factors resulting in very low, low, intermediate and high risk groups. The median survival was >31.4 months for very low risk patients compared to 14.5 months for low risk, 4.1 months for intermediate risk and 1.2 months for high risk (p<0.001). Conclusions These data suggest that a model that considers performance status, extent of disease, primary tumor site and serum albumin represents a simple model to accurately predict survival for patients with stage IV cancer who are potential candidates for radiation therapy.

    Background The ONCO-i2b2 platform is a bioinformatics tool designed to integrate clinical and research data and support translational research in oncology. It is implemented by the University of Pavia and the IRCCS Fondazione Maugeri hospital (FSM), and grounded on the software developed by the Informatics for Integrating Biology and the Bedside (i2b2) research center. I2b2 has delivered an open source suite based on a data warehouse, which is efficiently interrogated to find sets of interesting patients through a query tool interface. Methods Onco-i2b2 integrates data coming from multiple sources and allows the users to jointly query them. I2b2 data are then stored in a data warehouse, where facts are hierarchically structured as ontologies. Onco-i2b2 gathers data from the FSM pathology unit (PU) database and from the hospital biobank and merges them with the clinical information from the hospital information system. Our main effort was to provide a robust integrated research environment, giving a particular emphasis to the integration process and facing different challenges, consecutively listed: biospecimen samples privacy and anonymization; synchronization of the biobank database with the i2b2 data warehouse through a series of Extract, Transform, Load (ETL) operations; development and integration of a Natural Language Processing (NLP) module, to retrieve coded information, such as SNOMED terms and malignant tumors (TNM) classifications, and clinical tests results from unstructured medical records. Furthermore, we have developed an internal SNOMED ontology rested on the NCBO BioPortal web services. Results Onco-i2b2 manages data of more than 6,500 patients with breast cancer diagnosis collected between 2001 and 2011 (over 390 of them have at least one biological sample in the cancer biobank), more than 47,000 visits and 96,000 observations over 960 medical concepts. Conclusions Onco-i2b2 is a concrete example of how integrated Information and Communication

    Purpose: To investigate whether high-dose thoracic radiation given twice daily during cisplatin-etoposide chemotherapy for limited small-cell lung cancer (LSCLC) improves survival, acute esophagitis, and local control rates relative to findings from Intergroup trial 0096 (47%, 27%, and 64%). Patients and Methods: Patients were accrued over a 3-year period from 22 US and Canadian institutions. Patients with LSCLC and good performance status were given thoracic radiation to 61.2 Gy over 5 weeks (daily 1.8-Gy fractions on days 1-22, then twice-daily 1.8-Gy fractions on days 23-33). Cisplatin (60 mg/m{sup 2} IV) was given on day 1 and etoposide (120 mg/m{sup 2} IV) on days 1-3 and days 22-24, followed by 2 cycles of cisplatin plus etoposide alone. Patients who achieved complete response were offered prophylactic cranial irradiation. Endpoints included overall and progression-free survival; severe esophagitis (Common Toxicity Criteria v 2.0) and treatment-related fatalities; response (Response Evaluation Criteria in Solid Tumors); and local control. Results: Seventy-two patients were accrued from June 2003 through May 2006; 71 were evaluable (median age 63 years; 52% female; 58% Zubrod 0). Median survival time was 19 months; at 2 years, the overall survival rate was 36.6% (95% confidence interval [CI] 25.6%-47.7%), and progression-free survival 19.7% (95% CI 11.4%-29.6%). Thirteen patients (18%) experienced severe acute esophagitis, and 2 (3%) died of treatment-related causes; 41% achieved complete response, 39% partial response, 10% stable disease, and 6% progressive disease. The local control rate was 73%. Forty-three patients (61%) received prophylactic cranial irradiation. Conclusions: The overall survival rate did not reach the projected goal; however, rates of esophagitis were lower, and local control higher, than projected.

    Purpose: To assess ultrahigh (UH; prostate-specific antigen [PSA]levels {>=}50 ng/ml) patient outcomes by comparison to other high-risk patient outcomes and to identify outcome predictors. Methods and Materials: Prostate cancer patients (PCP) from two Phase III Radiation Therapy Oncology Group clinical trials (studies 9202 and 9413) were divided into two groups: high-risk patients with and without UH baseline PSA levels. Predictive variables included age, Gleason score, clinical T stage, Karnofsky performance score, and treatment arm. Outcomes included overall survival (OS), distant metastasis (DM), and biochemical failure (BF). Unadjusted and adjusted hazard ratios (HRs) were calculated using either the Cox or Fine and Gray's regression model with associated 95% confidence intervals (CI) and p values. Results: There were 401 patients in the UH PSA group and 1,792 patients in the non-UH PSA PCP group of a total of 2,193 high-risk PCP. PCP with UH PSA were found to have inferior OS (HR, 1.19; 95% CI, 1.02-1.39, p = 0.02), DM (HR, 1.51; 95% CI, 1.19-1.92; p = 0.0006), and BF (HR, 1.50; 95% CI, 1.29-1.73; p < 0.0001) compared to other high-risk PCP. In the UH cohort, PSA level was found to be a significant factor for the risk of DM (HR, 1.01; 95% CI, 1.001-1.02) but not OS and BF. Gleason grades of 8 to 10 were found to consistently predict for poor OS, DM, and BF outcomes (with HR estimates ranging from 1.41-2.36) in both the high-risk cohort and the UH cohort multivariable analyses. Conclusions: UH PSA levels at diagnosis are related to detrimental changes in OS, DM, and BF. All three outcomes can be modeled by various combinations of all predictive variables tested.

    Few epidemiologic studies describe longitudinal liver chemistry (LC) elevations in cancer patients. A population-based retrospective cohort was identified from 31 Phase 2-3 oncology trials (excluding targeted therapies) conducted from 1985 to 2005 to evaluate background rates of LC elevations in patients (n = 3998) with or without liver metastases. Patients with baseline liver metastases (29% of patients) presented with a 3% prevalence of alanine transaminase (ALT) ≥ 3x upper limits normal (ULN) and 0.2% prevalence of bilirubin ≥ 3xULN. During follow-up, the incidence (per 1000 person-months) of new onset ALT elevations ≥3xULN was 6.1 (95% CI: 4.5, 8.0) and 2.2 (95% CI: 0.9, 4.5) in patients without and with liver metastases, respectively. No new incident cases of ALT and bilirubin elevations suggestive of severe liver injury occurred among those with liver metastases; a single case occurred among those without metastasis. Regardless of the presence of liver metastases, LC elevations were rare in cancer patients during oncology trials, which may be due to enrollment criteria. Our study validates uniform thresholds for detection of LC elevations in oncology studies and serves as an empirical referent point for comparing liver enzyme abnormalities in oncology trials of novel targeted therapies. These data support uniform LC stopping criteria in oncology trials. PMID:27025923

    Stereotactic ablative radiotherapy is a modern cancer treatment strategy able to deliver highly focused radiation in one or a few fractions with a radical intent in several clinical settings. Young radiation oncologists need a constant and tailored update in this context to improve patient care in daily clinical practice. A recent meeting of AIRO Giovani (AIRO--Young Members Working Group) was specifically addressed to this topic, presenting state-of-the-art knowledge, based on the latest evidence in this field. Highlights of the congress are summarized and presented in this report, including thorough contributions of the speakers dealing with the role of stereotactic ablative radiotherapy in both oncological and non-oncological diseases, divided according to anatomical and clinical scenarios: intra-cranial settings (brain malignant primary tumors, metastases, benign tumors and functional disorders) and extra-cranial indications (lung primary tumors and metastases, thoracic re-irradiation, liver, lymph node and bone metastases, prostate cancer). With literature data discussed during the congress as a background, stereotactic ablative radiotherapy has proved to be a consolidated treatment approach in specific oncological and non-oncological scenarios, as well as a promising option in other clinical settings, requiring a further prospective validation in the near future. We herein present an updated overview of stereotactic ablative radiotherapy use in the clinic. PMID:25688503

    Purpose: To assess the early clinical outcomes with concurrent cisplatin and extended-field intensity-modulated radiotherapy (EF-IMRT) for carcinoma of the cervix. Methods and Materials: Thirty-six patients with Stage IB2-IVA cervical cancer treated with EF-IMRT were evaluated. The pelvic lymph nodes were involved in 19 patients, and of these 19 patients, 10 also had para-aortic nodal disease. The treatment volume included the cervix, uterus, parametria, presacral space, upper vagina, and pelvic, common iliac, and para-aortic nodes to the superior border of L1. Patients were assessed for acute toxicities according to the National Cancer Institute Common Toxicity Criteria for Adverse Events, version 3.0. All late toxicities were scored with the Radiation Therapy Oncology Group late toxicity score. Results: All patients completed the prescribed course of EF-IMRT. All but 2 patients received brachytherapy. Median length of treatment was 53 days. The median follow-up was 18 months. Acute Grade {>=}3 gastrointestinal, genitourinary, and myelotoxicity were seen in 1, 1, and 10 patients, respectively. Thirty-four patients had complete response to treatment. Of these 34 patients, 11 developed recurrences. The first site of recurrence was in-field in 2 patients (pelvis in 1, pelvis and para-aortic in 1) and distant in 9 patients. The 2-year actuarial locoregional control, disease-free survival, overall survival, and Grade {>=}3 toxicity rates for the entire cohort were 80%, 51%, 65%, and 10%, respectively. Conclusion: Extended-field IMRT with concurrent chemotherapy was tolerated well, with acceptable acute and early late toxicities. The locoregional control rate was good, with distant metastases being the predominant mode of failure. We are continuing to accrue a larger number of patients and longer follow-up data to further extend our initial observations with this approach.

    Patients with advanced testicular cancer (TC) have a very good long-term prognosis owing to cisplatin-based polychemotherapy. Platinum is believed to be excreted at a rapid rate via urine within weeks after chemotherapy. As a new, highly sensitive method has become available detecting even natural background platinum levels in body fluids, this study was set up to analyze urinary and serum platinum levels in long-term survivors of testicular neoplasm after cisplatin based polychemotherapy and to correlate clinical data with urinary and serum platinum levels. Urinary platinum concentrations were measured in 64 healthy controls (C) and 22 male patients (TC) 150 to 3022 days after the last application of i.v. cisplatin using voltammetry after UV-photolysis. In the latter group (TC), serum platinum levels were measured as well. Clinical data were analysed as to long-term organ toxicity. Mean urinary platinum levels were 2700 times higher in the patient group (TC) than natural background noise (p < 0.0001). There was a decline of urinary and serum platinum levels over time, being significantly above normal even 8 years after cisplatin exposure. The only significant variables related to the urine platinum concentration were a) the interval between the last i.v. cisplatin application and time of study and b) the total dose given. Not significant were the number of chemotherapy cycles, pre-therapy renal disease, patient age, tumour resection before/after chemotherapy, site of pre/post therapy resection, clinical staging, histological subtypes or tumour markers. Post-therapy renal disease or peripheral nerve damage were not significantly associated with urinary platinum levels. Our data indicate that even 8 years after cisplatin based chemotherapy 500 times elevated urinary and serum platinum levels can be measured in testicular cancer patients. No organ toxicity related to long-term platinum excretion could be detected. This may be due to our small sample size. PMID

    Purpose Family history of cancer (CFH) is important for identifying individuals to receive genetic counseling/testing (GC/GT). Prior studies have demonstrated low rates of family history documentation and referral for GC/GT. Methods CFH quality and GC/GT practices for patients with breast (BC) or colon cancer (CRC) were assessed in 271 practices participating in the American Society of Clinical Oncology Quality Oncology Practice Initiative in fall 2011. Results A total of 212 practices completed measures regarding CFH and GC/GT practices for 10,466 patients; 77.4% of all medical records reviewed documented presence or absence of CFH in first-degree relatives, and 61.5% of medical records documented presence or absence of CFH in second-degree relatives, with significantly higher documentation for patients with BC compared with CRC. Age at diagnosis was documented for all relatives with cancer in 30.7% of medical records (BC, 45.2%; CRC, 35.4%; P ≤ .001). Referall for GC/GT occurred in 22.1% of all patients with BC or CRC. Of patients with increased risk for hereditary cancer, 52.2% of patients with BC and 26.4% of those with CRC were referred for GC/GT. When genetic testing was performed, consent was documented 77.7% of the time, and discussion of results was documented 78.8% of the time. Conclusion We identified low rates of complete CFH documentation and low rates of referral for those with BC or CRC meeting guidelines for referral among US oncologists. Documentation and referral were greater for patients with BC compared with CRC. Education and support regarding the importance of accurate CFH and the benefits of proactive high-risk patient management are clearly needed. PMID:24493722

    Purpose We evaluated the usefulness of the in vitro adenosine triphosphate-based chemotherapy response assay (ATP-CRA) for prediction of clinical response to fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer. Materials and Methods Tumor specimens of 86 patients with pathologically confirmed stage II colorectal adenocarcinoma were tested for chemosensitivity to fluorouracil. Chemosensitivity was determined by cell death rate (CDR) of drug-exposed cells, calculated by comparing the intracellular ATP level with that of untreated controls. Results Among the 86 enrolled patients who underwent radical surgery followed by fluorouracil-based adjuvant chemotherapy, recurrence was found in 11 patients (12.7%). The CDR ≥ 20% group was associated with better disease-free survival than the CDR < 20% group (89.4% vs. 70.1%, p=0.027). Multivariate analysis showed that CDR < 20% and T4 stage were poor prognostic factors for disease-free survival after fluorouracil-based adjuvant chemotherapy. Conclusion In stage II colorectal cancer, the in vitro ATP-CRA may be useful in identifying patients likely to benefit from fluorouracil-based adjuvant chemotherapy. PMID:26511802

    Cancer and its treatment can induce subjective and objective evidence of diminished functional capacity encompassing physical fatigue and cognitive impairment. Dexmethylphenidate (D-MPH; the D-isomer of methylphenidate) was evaluated for treatment of chemotherapy-related fatigue and cognitive impairment. A randomized, double-blind, placebo-controlled, parallel-group study evaluated the potential therapeutic effect and safety of D-MPH in the treatment of patients with chemotherapy-related fatigue. Change from baseline in the Functional Assessment of Chronic Illness Therapy-Fatigue Subscale (FACIT-F) total score at Week 8 was the primary outcome measure. One hundred fifty-four patients (predominantly with breast and ovarian cancers) were randomized and treated. Compared with placebo, D-MPH-treated subjects demonstrated a significant improvement in fatigue symptoms at Week 8 in the FACIT-F (P=0.02) and the Clinical Global Impression-Severity scores (P=0.02), without clinically relevant changes in hemoglobin levels. Cognitive function was not significantly improved. There was a higher rate of study drug-related adverse events (AEs) (48 of 76 [63%] vs. 22 of 78 [28%]) and a higher discontinuation rate because of AEs (8 of 76 [11%] vs. 1 of 78 [1.3%]) in D-MPH-treated subjects compared with placebo-treated subjects. The most commonly reported AEs independent of study drug relationship in D-MPH-treated subjects were headache, nausea, and dry mouth, and in placebo-treated subjects were headache, diarrhea, and insomnia. D-MPH produced significant improvement in fatigue in subjects previously treated with cytotoxic chemotherapy. Further studies with D-MPH or other agents to explore treatment response in chemotherapy-associated fatigue should be considered. PMID:19896571

    The 10th International Conference of the Asian Clinical Oncology Society (ACOS 2012) in conjunction with the 38th Annual Meeting of the Korean Cancer Association, was held on June 13 to 15 (3 days) 2012 at COEX Convention and Exhibition Center in Seoul, Korea. ACOS has a 20-year history starting from the first conference in Osaka, Japan, which was chaired by Prof. Tetsuo Taguchi and the ACOS conferences have since been conducted in Asian countries every 2 years. Under the theme of "Work Together to Make a Difference for Cancer Therapy in Asia", the 10th ACOS was prepared to discuss various subjects through a high-quality academic program, exhibition, and social events. The ACOS 2012 Committee was composed of the ACOS Organizing Committee, Honorary Advisors, Local Advisors, and ACOS 2012 Organizing Committee. The comprehensive academic program had a total of 92 sessions (3 Plenary Lectures, 1 Award Lectures, 1 Memorial Lectures, 9 Special Lectures, 15 Symposia, 1 Debate & Summary Sessions, 1 Case Conferences, 19 Educational Lectures, 1 Research & Development Session, 18 Satellite Symposia, 9 Meet the Professors, 14 Oral Presentations) and a total 292 presentations were delivered throughout the entire program. Amongst Free Papers, 462 research papers (110 oral presentations and 352 poster presentations) were selected to be presented. This conference was the largest of all ACOS conferences in its scale with around 1,500 participants from 30 countries. Furthermore, despite strict new financial policies and requirements governing fundraising alongside global economic stagnation, a total of 14 companies participated as sponsors and an additional 35 companies purchased 76 exhibition booths. Lastly, the conference social events provided attendees with a variety of opportunities to experience and enjoy Korea's rich culture and traditions during the Opening Ceremony, Welcome Reception, Invitee Dinner, Banquet, and Closing Ceremony.

    Background Chemotherapy is an effective treatment in the fight against many cancers. Medication errors in oncology can be particularly serious given the narrow therapeutic window of antineoplastic drugs and their high toxicities. Computerized prescriber order entry (cpoe) has consistently been shown to reduce medication errors and adverse drug events in various settings, but its use in the oncology setting has not been well established. To gain a better understanding of the meaningful use of cpoe systems in the outpatient chemotherapy setting, we undertook a systematic review of systemic therapy cpoe. Methods A province-wide expert panel consisting of clinical experts, health information professionals, and specialists in human factors design provided guidance in the development of the research questions, search terms, databases, and inclusion criteria. The systematic review was undertaken by a core team consisting of a medical oncologist, nurse, pharmacist, and methodologist. The medline, embase, cinahl, and compendex databases were searched for relevant evidence. Results The database searches resulted in 5642 hits, of which 9 met the inclusion criteria and were retained. In the oncology setting, cpoe systems generally reduce chemotherapy medication errors; however, specific types of errors increase with the use of cpoe. These systems affect practice both positively and negatively with respect to time, workload, and productivity. Conclusions Despite the paucity of oncology-specific research, cpoe should be used in outpatient chemotherapy delivery to reduce chemotherapy-related medication errors. Adoption by clinicians will be enhanced by cpoe processes that complement current practice and workflow processes. PMID:25089110

    Chemotherapy-induced nausea and vomiting (CINV) has long been one of the most troublesome adverse effects of chemotherapy, leading to significant detriments in quality of life and functioning, increased economic costs, and, in some cases, the discontinuation of effective cancer therapy. The past 2 decades have witnessed a dramatic increase in the number of effective antiemetic agents, with the introduction of the serotonin (5-hydroxytryptamine [5-HT₃]) receptor antagonists (ondansetron, granisetron, and palonosetron), the neurokinin-1 (NK₁) receptor antagonists (aprepitant and fosaprepitant), and the identification of other agents that have demonstrated efficacy against CINV, including corticosteroids. These agents often provide excellent control of emesis. Nausea, however, has proven more intractable, particularly in the days after administration of chemotherapy. Newer antiemetic agents under study may provide additional CINV control, particularly against delayed nausea. New agents undergoing review by the US Food and Drug Administration for the prevention of CINV include the novel NK₁ receptor antagonist rolapitant and a fixed-dose combination consisting of the novel NK₁ receptor antagonist netupitant and palonosetron (NEPA). Adherence to clinical practice guidelines has been shown to significantly improve CINV control. As antiemetic therapy continues to evolve, it will be important for clinicians to stay informed of new developments and changes in guidelines. PMID:24874107

    Limited research has been devoted to quality of life (QOL) of cancer patients in developing countries. To assess the feasibility of QOL assessment in a cohort of Tunisian cancer patients, the EORTC QLQ-C30 questionnaire was administered to 23 women treated with adjuvant chemotherapy for early breast cancer on an outpatient basis at baseline and during the 3rd cycle of chemotherapy. We observed a significant deterioration in physical functioning, cognitive functioning and social functioning during chemotherapy. However, a wide range of methodological and practical obstacles to routine QOL evaluation were identified through this study. Further improvement of cancer care infrastructure and public education is still needed before reliable QOL studies can be performed. PMID:19554983

    Background Computerized physician order entry (cpoe) systems allow for medical order management in a clinical setting. Use of a cpoe has been shown to significantly improve chemotherapy safety by reducing the number of prescribing errors. Usability of these systems has been identified as a critical factor in their successful adoption. However, there is a paucity of literature investigating the usability of cpoe for chemotherapy and describing the experiences of cancer care providers in implementing and using a cpoe system. Methods A mixed-methods study, including a national survey and a workshop, was conducted to determine the current status of cpoe adoption in Canadian oncology institutions, to identify and prioritize knowledge gaps in cpoe usability and adoption, and to establish a research agenda to bridge those gaps. Survey respondents were representatives of cancer care providers from each Canadian province. The workshop participants were oncology clinicians, human factors engineers, patient safety researchers, policymakers, and hospital administrators from across Canada, with participation from the United States. Results A variety of issues related to implementing and using a cpoe for chemotherapy were identified. The major issues concerned the need for better understanding of current practices of chemotherapy ordering, preparation, and administration; a lack of system selection and procurement guidance; a lack of implementation and maintenance guidance; poor cpoe usability and workflow support; and other cpoe system design issues. An additional three research themes for addressing the existing challenges and advancing successful adoption of cpoe for chemotherapy were identified: The need to investigate variances in workflows and practices in chemotherapy ordering and administrationThe need to develop best-practice cpoe procurement and implementation guidance specifically for chemotherapyThe need to measure the effects of cpoe implementation in medical

    For decades Western medicine has followed a biomedical model based on linear thinking and an individualized, disease-oriented doctor-patient relationship. Today this framework must be replaced by a biopsychosocial model based on complexity theory and a person-oriented medical team-patient relationship, taking into account the psychological and social determinants of health and disease. However, the new model is already proving no longer adequate or appropriate, and current events are urging us to develop an ecological model in which the medical team takes into account both individual illness and population health as a whole, since we are all part of the biosphere. In recent years, the rising costs of cancer treatment have raised a serious issue of economic sustainability. As the population of our planet, we now need to rapidly address this issue, and everyone of us must try to reduce their ecological footprint, measured as CO2 production. Medical oncologists need to reduce the ecological footprint of their professional activity by lowering the consumption of economic resources and avoiding environmental damage as much as possible. This new paradigm is endorsed by the Italian College of Hospital Medical Oncology Directors (CIPOMO). A working group of this organization has drafted the "Green Oncology Position Paper": a proposal of Italian medical oncology (in accordance with international guidelines) that oncologists, while aiming for the same end results, make a commitment toward the more appropriate management of health care and the careful use of resources in order to protect the environment and the ecosphere during the daily exercise of their professional activities.

    To identify molecular alterations in prostate cancers associating with relapse following neoadjuvant chemotherapy and radical prostatectomy patients with high-risk localized prostate cancer were enrolled into a phase I-II clinical trial of neoadjuvant chemotherapy with docetaxel and mitoxantrone followed by prostatectomy. Pre-treatment prostate tissue was acquired by needle biopsy and post-treatment tissue was acquired by prostatectomy. Prostate cancer gene expression measurements were determined in 31 patients who completed 4 cycles of neoadjuvant chemotherapy. We identified 141 genes with significant transcript level alterations following chemotherapy that associated with subsequent biochemical relapse. This group included the transcript encoding monoamine oxidase A (MAOA). In vitro, cytotoxic chemotherapy induced the expression of MAOA and elevated MAOA levels enhanced cell survival following docetaxel exposure. MAOA activity increased the levels of reactive oxygen species and increased the expression and nuclear translocation of HIF1α. The suppression of MAOA activity using the irreversible inhibitor clorgyline augmented the apoptotic responses induced by docetaxel. In summary, we determined that the expression of MAOA is induced by exposure to cytotoxic chemotherapy, increases HIF1α, and contributes to docetaxel resistance. As MAOA inhibitors have been approved for human use, regimens combining MAOA inhibitors with docetaxel may improve clinical outcomes. PMID:25198178

    Chemotherapy-induced intestinal mucositis is characterized by pain and a pro-inflammatory tissue response. Rat models are frequently used in mucositis disease investigations yet little is known about the presence of pain in these animals, the ability of analgesics to ameliorate the condition, or the effect that analgesic administration may have on study outcomes. This study investigated different classes of analgesics with the aim of determining their analgesic effects and impact on research outcomes of interest in a rat model of mucositis. Female DA rats were allocated to 8 groups to include saline and chemotherapy controls (n = 8). Analgesics included opioid derivatives (buprenorphine; 0.05mg/kg and tramadol 12.5mg/kg) and NSAID (carprofen; 15mg/kg) in combination with either saline or 5-Fluorouracil (5-FU; 150mg/kg). Research outcome measures included daily clinical parameters, pain score and gut histology. Myeloperoxidase assay was performed to determine gut inflammation. At the dosages employed, all agents had an analgesic effect based on behavioural pain scores. Jejunal myeloperoxidase activity was significantly reduced by buprenorphine and tramadol in comparison to 5-FU control animals (53%, p = 0.0004 and 58%, p = 0.0001). Carprofen had no ameliorating effect on myeloperoxidase levels. None of the agents reduced the histological damage caused by 5-FU administration although tramadol tended to increase villus length even when administered to healthy animals. These data provide evidence that carprofen offers potential as an analgesic in this animal model due to its pain-relieving efficacy and minimal effect on measured parameters. This study also supports further investigation into the mechanism and utility of opioid agents in the treatment of chemotherapy-induced mucositis. PMID:27463799

    Genomic discoveries have transformed the practice of oncology and cancer prevention. Diagnostic and therapeutic advances based on cancer genomics developed during a time when it was possible to patent genes. A case before the Supreme Court, Association for Molecular Pathology v Myriad Genetics, Inc seeks to overturn patents on isolated genes. Although the outcomes are uncertain, it is suggested here that the Supreme Court decision will have few immediate effects on oncology practice or research but may have more significant long-term impact. The Federal Circuit court has already rejected Myriad's broad diagnostic methods claims, and this is not affected by the Supreme Court decision. Isolated DNA patents were already becoming obsolete on scientific grounds, in an era when human DNA sequence is public knowledge and because modern methods of next-generation sequencing need not involve isolated DNA. The Association for Molecular Pathology v Myriad Supreme Court decision will have limited impact on new drug development, as new drug patents usually involve cellular methods. A nuanced Supreme Court decision acknowledging the scientific distinction between synthetic cDNA and genomic DNA will further mitigate any adverse impact. A Supreme Court decision to include or exclude all types of DNA from patent eligibility could impact future incentives for genomic discovery as well as the future delivery of medical care. Whatever the outcome of this important case, it is important that judicial and legislative actions in this area maximize genomic discovery while also ensuring patients' access to personalized cancer care.

    Background and objectives Relevant heterogeneity exists among Postgraduate Schools in Medical Oncology, also within the same country. In order to provide a comprehensive overview of the landscape of Italian Postgraduate Schools in Medical Oncology, the Italian Association of Medical Oncology (AIOM) undertook an online survey, inviting all the residents to describe their daily activities and to express their overall satisfaction about their programs. Methods A team composed of five residents and three consultants in medical oncology prepared a 38 items questionnaire that was published online in a reserved section, accessible through a link sent by e-mail. Residents were invited to anonymously fill in the questionnaire that included the following sub-sections: quality of teaching, clinical and research activity, overall satisfaction. Results Three-hundred and eleven (57%) out of 547 invited residents filled in the questionnaire. Two-hundred and twenty-three (72%) participants declared that attending lessons was frequently difficult and 153 (49%) declared they did not gain substantial improvement in their knowledge from them. Fifty-five percent stated that they did not receive lessons on palliative care. Their overall judgment about didactic activity was low in 63% of the interviewed. The satisfaction for clinical activity was in 86% of cases good: 84% recognized that, during the training period, they acquired a progressive independence on patients' management. About research activity, the majority (79%) of participants in the survey was actively engaged in managing patients included in clinical trials but the satisfaction level for the involvement in research activities was quite low (54%). Overall, 246 residents (79%) gave a positive global judgment of their Medical Oncology Schools. Conclusions The landscape of Italian Postgraduate Schools in Medical Oncology is quite heterogeneous across the country. Some improvements in the organization of teaching and in the

    Purpose Neoadjuvant chemotherapy for muscle invasive bladder cancer has been shown to confer a survival advantage in phase III studies. Although cisplatin and gemcitabine are often used in this setting, a comprehensive evaluation of this regimen is lacking. In this review we summarize the efficacy of neoadjuvant cisplatin and gemcitabine chemotherapy for muscle invasive bladder cancer based on currently published studies. Materials and Methods A systematic literature review was conducted in April 2012 searching MEDLINE® databases. Articles were selected if they included patients with muscle invasive bladder cancer, evaluated the combination of cisplatin and gemcitabine as neoadjuvant treatment, and reported pathological data after cystectomy. Cisplatin and gemcitabine dosing regimens and clinical data were further summarized using weighted averages. Results Seven studies encompassing 164 patients were published between 2007 and 2012. The majority of patients (79%) received cisplatin and gemcitabine on a 21-day cycle. A weighted average of 19.2 lymph nodes was obtained at cystectomy, and 29.7% of patients were found to have pN1 disease. Pathological down staging to pT0 and less than pT2 occurred in 42 (25.6%) and 67 (46.5%) patients, respectively. Conclusions Neoadjuvant cisplatin and gemcitabine yield appreciable pathological response rates in patients with muscle invasive bladder cancer. Since pathological response has been implicated as a potential surrogate for survival in muscle invasive bladder cancer, these data suggest that neoadjuvant cisplatin and gemcitabine may warrant further prospective assessment.

    2010-01-01

    Complementary and alternative medicines (CAMs), in particular herbal medicines, are commonly used by cancer patients in conjunction with chemotherapy treatment for their anticancer properties and supportive care. However, the effects of many of these herbs are not well-documented due to limited studies done on them. Severe herb-drug interactions (HDIs) have been recorded in some cases, and failure to recognize these harmful HDIs can lead to dire consequences in cancer patients. This study discusses clinically-relevant interactions between anticancer drugs (ACDs) and herbs classified into 7 categories: cancer treatment and prevention, immune-system-related, alopecia, nausea and vomiting, peripheral neuropathy and pain, inflammation, and fatigue. Some promising patents which contain these herbs and thus may manifest these interactions are also presented in this article. Pharmacokinetic interactions involved mainly induction or inhibition of the cytochrome P450 isozymes and p-glycoprotein, while pharmacodynamic interactions were related to increased risks of central nervous system-related effects, hepatotoxicity and bleeding, among others. Clinicians should be vigilant when treating cancer patients who take CAMs with concurrent chemotherapy since they face a high risk of HDIs. These HDIs can be minimized or avoided by selecting herb-drug pairs which are less likely to interact. Furthermore, close monitoring of pharmacological effects and plasma drug levels should be carried out to avoid toxicity and ensure adequate chemotherapeutic coverage in patients with cancer.

    Compared with intravenous (i.v.) chemotherapy, oral administration is convenient, requires fewer healthcare resources, is generally preferred by patients, and may be appropriate in older people with breast, colorectal and lung cancers. The effects of organ dysfunction on drug metabolism and drug interactions in patients with multiple comorbidities must be considered but are not specific to oral chemotherapy. Single-agent oral chemotherapy with capecitabine or vinorelbine is active in older patients with advanced or metastatic breast cancer. Choice of treatment is based mainly on different safety profiles. In the adjuvant treatment of colorectal cancer (CRC), single-agent oral capecitabine is an effective alternative to i.v. fluorouracil (5-FU) regimens. In metastatic CRC, oral, single-agent capecitabine has recently shown encouraging median overall survival in combination with bevacizumab. In non-small cell lung cancer, fit older patients, like their younger counterparts, benefit from platinum-based doublets, with carboplatin preferred to cisplatin. Single agent vinorelbine is an option for those less suited to combination chemotherapy, and oral may be an alternative to i.v. administration. For elderly cancer patients in general, metronomic chemotherapy combines good tolerability with acceptable activity. PMID:26340809

We experienced that diagnostic problems which are characterized by fuzzy, uncertain knowledge and overlapping signs, still reveal some kind of patterns that can be transferred into a computer-based decision model. We applied a multi-stage evaluation process to assess the system's diagnostic performance. Depending on how system behavior was compared to presumably correct judgment of a case the correctness rate for closed cases with all data available varied between 58% and 71%, the overall rate after critical review was 84%. However, the real time behavior of our approach which data becoming available as time passes still has to be evaluated and observational studies need to be conducted. PMID:23522434

    Prompt identification and treatment of life-threatening oncological conditions is of utmost importance and should always be included in the differential diagnosis. Oncological emergencies can have a myriad of presentations ranging from mechanical obstruction due to tumor growth to metabolic conditions due to abnormal secretions from the tumor. Notably, hematologic and infectious conditions may complicate the presentation of oncological emergencies. Advanced testing and imaging is generally required to recognize these serious presentations of common malignancies.

    Follow-up of operable breast cancer patients takes up a significant proportion of British oncologists' time, with 90% seeing 5-50 patients each week. Procedures vary greatly, but, in patients treated by surgery and radiotherapy, care is usually shared, with alternating visits to see each team. Currently, the general practitioner has sole responsibility for follow-up in less than 3% of patients. They tend to be followed up in general, rather than specialist, clinics. There is almost universal agreement that routine blood tests, radiographs and scans are not indicated as part of routine follow-up, but the role of mammography in evaluating an irradiated breast remains a source of debate. Just over a half of the oncologists surveyed order baseline mammography of both treated and contralateral breasts, usually between 6 and 12 months after local excision and radiotherapy, with further follow-up 1-3-yearly thereafter. Ten per cent of the participating oncologists never suggest follow-up mammography. Patients tend to be followed in oncology clinics at 3-4-monthly intervals for the first 2 years, 6-monthly in the third and fourth years and, thereafter, yearly. Fifteen per cent of oncologists discharge patients at 5 years, with the discharge rate rising to 43% at 10 years; around one-third modify follow-up according to the age of the patient. The aims of follow-up were seen to include detection of curable disease, but other goals were perceived as equally important (e.g. detection of iatrogenic problems, audit, counselling, education and the provision of early palliation of incurable and metastatic disease. Breast cancer is no longer seen as an absolute contraindication to either pregnancy or the use of hormone replacement therapy (HRT); however, oncologists are uncertain about the appropriate use of HRT, either alone or with tamoxifen. This audit highlights a number of research areas: the identification of the appropriate site and skill-mix for follow-up of patients

    Chemotherapy is prone to medication error resulting from complexities in ordering and administration. Computerized physician order entry (CPOE) has been established as an important tool to minimize such errors and hence improve patient safety. As a leading Canadian advisory body in oncology, Cancer Care Ontario (CCO) has been a champion in developing and implementing its own cancer systemic therapy CPOE, the Oncology Patient Information System (OPIS). This article reviews and consolidates principles for oncology CPOE systems as found in the literature and in guidelines created by three international oncology organizations (American Society of Clinical Oncology, Clinical Oncological Society of Australia, and CCO). It then evaluates OPIS by these standards and provides a working example of what a cancer CPOE system should look like. This document can therefore be used as a framework to help develop and evaluate cancer CPOE platforms in different national settings. As end users, oncologists are considered key stakeholders in developing such systems and thus should be well informed about CPOE principles to help make decisions on the appropriate implementation of these platforms in their local practice settings. In addition, oncologists are also important champions for the successful uptake of oncology CPOE platforms and would benefit from a better understanding of whether proposed or existing local CPOE systems meet established standards.

    Neuroimaging research often relies on clinically acquired magnetic resonance imaging (MRI) datasets that can originate from multiple institutions. Such datasets are characterized by high heterogeneity of modalities and variability of sequence parameters. This heterogeneity complicates the automation of image processing tasks such as spatial co-registration and physiological or functional image analysis. Given this heterogeneity, conventional processing workflows developed for research purposes are not optimal for clinical data. In this work, we describe an approach called Heterogeneous Optimization Framework (HOF) for developing image analysis pipelines that can handle the high degree of clinical data non-uniformity. HOF provides a set of guidelines for configuration, algorithm development, deployment, interpretation of results and quality control for such pipelines. At each step, we illustrate the HOF approach using the implementation of an automated pipeline for Multimodal Glioma Analysis (MGA) as an example. The MGA pipeline computes tissue diffusion characteristics of diffusion tensor imaging (DTI) acquisitions, hemodynamic characteristics using a perfusion model of susceptibility contrast (DSC) MRI, and spatial cross-modal co-registration of available anatomical, physiological and derived patient images. Developing MGA within HOF enabled the processing of neuro-oncology MR imaging studies to be fully automated. MGA has been successfully used to analyze over 160 clinical tumor studies to date within several research projects. Introduction of the MGA pipeline improved image processing throughput and, most importantly, effectively produced co-registered datasets that were suitable for advanced analysis despite high heterogeneity in acquisition protocols.
