Robotic surgery for cancer.  

PubMed

Currently, robot-assisted surgery is the most common type of robotic surgery used. In robot-assisted surgery, the operator is a surgeon, not a robotic system. Robotic systems assist the surgeons, but do not operate automatically. In this section, we focus on the master-slave type, which is the predominant type of robotic surgery used in cancer treatment, and discuss the role, present status, and the future of surgical robotic system in cancer treatment. In addition, the advantages and disadvantages of a robotic system are discussed, but further development of technologies and equipment is necessary to allow the safe, widespread introduction of a robotic system in more advanced surgery for malignant tumors. Such advances in the surgical robotic system will hopefully overcome the remaining problems and provide the ultimate minimally invasive surgery for cancer treatment. PMID:23528720

Improving the outcomes in gastric cancer surgery  

PubMed Central

Gastric cancer remains a significant health problem worldwide and surgery is currently the only potentially curative treatment option. Gastric cancer surgery is generally considered to be high risk surgery and five-year survival rates are poor, therefore a continuous strive to improve outcomes for these patients is warranted. Fortunately, in the last decades several potential advances have been introduced that intervene at various stages of the treatment process. This review provides an overview of methods implemented in pre-, intra- and postoperative stage of gastric cancer surgery to improve outcome. Better preoperative risk assessment using comorbidity index (e.g., Charlson comorbidity index), assessment of nutritional status (e.g., short nutritional assessment questionnaire, nutritional risk screening - 2002) and frailty assessment (Groningen frailty indicator, Edmonton frail scale, Hopkins frailty) was introduced. Also preoperative optimization of patients using prehabilitation has future potential. Implementation of fast-track or enhanced recovery after surgery programs is showing promising results, although future studies have to determine what the exact optimal strategy is. Introduction of laparoscopic surgery has shown improvement of results as well as optimization of lymph node dissection. Hyperthermic intraperitoneal chemotherapy has not shown to be beneficial in peritoneal metastatic disease thus far. Advances in postoperative care include optimal timing of oral diet, which has been shown to reduce hospital stay. In general, hospital volume, i.e., centralization, and clinical audits might further improve the outcome in gastric cancer surgery. In conclusion, progress has been made in improving the surgical treatment of gastric cancer. However, gastric cancer treatment is high risk surgery and many areas for future research remain.

Intraoperative imaging-guided cancer surgery: from current fluorescence molecular imaging methods to future multi-modality imaging technology.  

PubMed

Cancer is a major threat to human health. Diagnosis and treatment using precision medicine is expected to be an effective method for preventing the initiation and progression of cancer. Although anatomical and functional imaging techniques such as radiography, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) have played an important role for accurate preoperative diagnostics, for the most part these techniques cannot be applied intraoperatively. Optical molecular imaging is a promising technique that provides a high degree of sensitivity and specificity in tumor margin detection. Furthermore, existing clinical applications have proven that optical molecular imaging is a powerful intraoperative tool for guiding surgeons performing precision procedures, thus enabling radical resection and improved survival rates. However, detection depth limitation exists in optical molecular imaging methods and further breakthroughs from optical to multi-modality intraoperative imaging methods are needed to develop more extensive and comprehensive intraoperative applications. Here, we review the current intraoperative optical molecular imaging technologies, focusing on contrast agents and surgical navigation systems, and then discuss the future prospects of multi-modality imaging technology for intraoperative imaging-guided cancer surgery.

[Prostate cancer treatment by da Vinci surgery].  

PubMed

Minimally invasive laparoscopic surgery replaces many open surgery procedures in urology due to its advantages concerning post-operative morbidity. However, the technical challenges and need of learning have limited the application of this method to the work of highly qualified surgeons. The introduction of da Vinci surgical system has offered important technical advantages compared to the laparoscopic surgical procedure. Robot-assisted radical prostatectomy became a largely accepted procedure. It has paved the way for urologists to start other, more complex operations, decreasing this way the operative morbidity. The purpose of this article is to overview the history of robotic surgery, its current and future states in the treatment of the cancer. We present our robot-assisted radical prostatectomy and the results. PMID:25260081

Minimally invasive surgery in gastric cancer  

PubMed Central

Minimally invasive surgery for gastric cancer has rapidly gained popularity due to the early detection of early gastric cancer. As advances in instruments and the accumulation of laparoscopic experience increase, laparoscopic techniques are being used for less invasive but highly technical procedures. Recent evidence suggests that the short- and long-term outcomes of minimally invasive surgery for early gastric cancer and advanced gastric cancer are comparable to those of conventional open surgery. However, these results should be confirmed by large-scale multicenter prospective randomized controlled clinical trials. PMID:25339802

Mini-invasive surgery for colorectal cancer.  

PubMed

Laparoscopic techniques have been extensively used for the surgical management of colorectal cancer during the last two decades. Accumulating data have demonstrated that laparoscopic colectomy is associated with better short-term outcomes and equivalent oncologic outcomes when compared with open surgery. However, some controversies regarding the oncologic quality of mini-invasive surgery for rectal cancer exist. Meanwhile, some progresses in colorectal surgery, such as robotic technology, single-incision laparoscopic surgery, natural orifice specimen extraction, and natural orifice transluminal endoscopic surgery, have been made in recent years. In this article, we review the published data and mainly focus on the current status and latest advances of mini-invasive surgery for colorectal cancer. PMID:24589210

Anesthetic Techniques and Cancer Recurrence after Surgery  

PubMed Central

Many of the most common anesthetics are used in surgical oncology, yet effects on cancer cells are still not known. Anesthesia technique could differentially affect cancer recurrence in oncologic patients undergoing surgery, due to immunosuppression, stimulation of angiogenesis, and dissemination of residual cancer cells. Data support the use of intravenous anesthetics, such as propofol anesthesia, thanks to antitumoral protective effects inhibiting cyclooxygenase 2 and prostaglandins E2 in cancer cells, and stimulation of immunity response; a restriction in the use of volatile anesthetics; restriction in the use of opioids as they suppress humoral and cellular immunity, and their chronic use favors angiogenesis and development of metastases; use of locoregional anesthesia compared with general anesthesia, as locoregional appears to reduce cancer recurrence after surgery. However, these findings must be interpreted cautiously as there is no evidence that simple changes in the practice of anesthesia can have a positive impact on postsurgical survival of cancer patients.

Lung cancer surgery: an up to date  

PubMed Central

According to the International Agency for Research on Cancer (IARC) GLOBOCAN World Cancer Report, lung cancer affects more than 1 million people a year worldwide. In Greece according to the 2008 GLOBOCAN report, there were 6,667 cases recorded, 18% of the total incidence of all cancers in the population. Furthermore, there were 6,402 deaths due to lung cancer, 23.5% of all deaths due to cancer. Therefore, in our country, lung cancer is the most common and deadly form of cancer for the male population. The most important prognostic indicator in lung cancer is the extent of disease. The Union Internationale Contre le Cancer (UICC) and the American Joint Committee for Cancer Staging (AJCC) developed the tumour, node, and metastases (TNM) staging system which attempts to define those patients who might be suitable for radical surgery or radical radiotherapy, from the majority, who will only be suitable for palliative measures. Surgery has an important part for the therapy of patients with lung cancer. “Lobectomy is the gold standard treatment”. This statement may be challenged in cases of stage Ia cancer or in patients with limited pulmonary function. In these cases an anatomical segmentectomy with lymph node dissection is an acceptable alternative. Chest wall invasion is not a contraindication to resection. En-bloc rib resection and reconstruction is the treatment of choice. N2 disease represents both a spectrum of disease and the interface between surgical and non-surgical treatment of lung cancer Evidence from trials suggests that multizone or unresectable N2 disease should be treated primarily by chemoradiotherapy. There may be a role for surgery if N2 is downstaged to N0 and lobectomy is possible, but pneumonectomy is avoidable. Small cell lung cancer (SCLC) is considered a systemic disease at diagnosis, because the potential for hematogenous and lymphogenic metastases is very high. The efficacy of surgical intervention for SCLC is not clear. Lung cancer resection can be performed using several surgical techniques. Video-assisted thoracoscopic surgery (VATS) lobectomy is a safe, efficient, well accepted and widespread technique among thoracic surgeons. The 5-year survival rate following complete resection of lung cancer is stage dependent. Incomplete resection rarely is useful and cures the patient. PMID:24102017

Fertility sparing surgery in early stage epithelial ovarian cancer  

PubMed Central

Objective Fertility sparing surgery (FSS) is a strategy often considered in young patients with early epithelial ovarian cancer. We investigated the role and the outcomes of FSS in eEOC patients who underwent comprehensive surgery. Methods From January 2003 to January 2011, 24 patients underwent fertility sparing surgery. Eighteen were one-to-one matched and balanced for stage, histologic type and grading with a group of patients who underwent radical comprehensive staging (n=18). Demographics, surgical procedures, morbidities, pathologic findings, recurrence-rate, pregnancy-rate and correlations with disease-free survival were assessed. Results A total of 36 patients had a complete surgical staging including lymphadenectomy and were therefore analyzed. Seven patients experienced a recurrence: four (22%) in the fertility sparing surgery group and three (16%) in the control group (p=not significant). Sites of recurrence were: residual ovary (two), abdominal wall and peritoneal carcinomatosis in the fertility sparing surgery group; pelvic (two) and abdominal wall in the control group. Recurrences in the fertility sparing surgery group appeared earlier (mean, 10.3 months) than in radical comprehensive staging group (mean, 53.3 months) p<0.001. Disease-free survival were comparable between the two groups (p=0.422). No deaths were reported. All the patients in fertility sparing surgery group recovered a regular period. Thirteen out of 18 (72.2%) attempted to have a pregnancy. Five (38%) achieved a spontaneous pregnancy with a full term delivery. Conclusion Fertility sparing surgery in early epithelial ovarian cancer submitted to a comprehensive surgical staging could be considered safe with oncological results comparable to radical surgery group.

Irradiation and surgery for selected cancers  

SciTech Connect

Combinations of radiation therapy with surgery originated when the surgeon thought he had transected cancer. Unrealistic expectations, however, plagued these combinations until it was appreciated that the dose required to eradicate a given cancerous mass varied primarily with its volume and the associated oxygen tension of its cells. This helped to establish the rationale for combining irradiation and surgery and enabled the radiation therapist to more closely tailor dose needs to each specific clinical problem. Tailoring of dose remains crude. Our greatest errors continue to be attributable to poor definition of tumor extent and the underestimation of residual tumor volume. We need more precise information from the surgeon and pathologist along with greater knowledge of patterns of spread. To the degree that such added information becomes available, we have the means to increase loco-regional control rates.

Extent of Primary Breast Cancer Surgery: Standards and Individualized Concepts  

PubMed Central

Surgery is still a main therapeutic option in breast cancer treatment. Nowadays, methods of resection and reconstruction vary according to different tumors and patients. This review presents and discusses standards of care and arising questions on how radical primary breast cancer surgery should be according to different clinical situations. In most early breast cancer patients, breast conservation is the method of choice. The discussion on resection margins is still controversial as different studies show conflicting results. Modified radical mastectomy is the standard in locally advanced breast cancer patients, although there are different promising approaches to spare skin or even the nipple-areola complex. A sentinel node biopsy is the standard of care in clinically node-negative invasive breast cancer patients, whereas the significance of axillary lymphonodectomy seems to be questioned through a number of different findings. Although there are interesting findings to modify surgical approaches in very young or elderly breast cancer patients, it will always be an individualized approach if we do not adhere to current guidelines. Up to date, there are no special surgical procedures in BRCA mutation carriers or patients of high-risk families. PMID:24647774

High Rate of Sexual Dysfunction Following Surgery for Rectal Cancer  

PubMed Central

Purpose Although rectal cancer is a very common malignancy and has an improved cure rate in response to oncological treatment, research on rectal-cancer survivors' sexual function remains limited. Sexual dysfunction (SD) after rectal cancer treatment was measured, and possible predisposing factors that may have an impact on the development of this disorder were identified. Methods Patients undergoing curative rectal cancer surgery from January 2012 to September 2013 were surveyed using questionnaires. The female sexual function index or the International Index of Erectile Function was recorded. A multiple logistic regression was used to test associations of clinical factors with outcomes. Results Fifty-six men (56%) and 28 women (44%) who completed the questionnaire were included in the study. A total of 76 patients of the 86 patients (90.5%) with the diagnosis of rectal cancer who were included in this study reported different levels of SD after radical surgery. A total of 64 patients (76%) from the whole cohort reported moderate to severe SD after treatment of rectal cancer. Gender (P = 0.011) was independently associated with SD. Female patients reported significantly higher rates of moderate to severe SD than male patients. Patients were rarely treated for dysfunction. Conclusion Sexual problems after surgery for rectal cancer are common, but patients are rarely treated for SD. Female patients reported higher rates of SD than males. These results point out the importance of sexual (dys)function in survivors of rectal cancer. More attention should be drawn to this topic for clinical and research purposes. PMID:25360427

Transanal endoscopic surgery in rectal cancer  

PubMed Central

Total mesorectal excision (TME) is the standard treatment for rectal cancer, but complications are frequent and rates of morbidity, mortality and genitourinary alterations are high. Transanal endoscopic microsurgery (TEM) allows preservation of the anal sphincters and, via its vision system through a rectoscope, allows access to rectal tumors located as far as 20 cm from the anal verge. The capacity of local surgery to cure rectal cancer depends on the risk of lymph node invasion. This means that correct preoperative staging of the rectal tumor is necessary. Currently, local surgery is indicated for rectal adenomas and adenocarcinomas invading the submucosa, but not beyond (T1). Here we describe the standard technique for TEM, the different types of equipment used, and the technical limitations of this approach. TEM to remove rectal adenoma should be performed in the same way as if the lesion were an adenocarcinoma, due to the high percentage of infiltrating adenocarcinomas in these lesions. In spite of the generally good results with T1, some authors have published surprisingly high recurrence rates; this is due to the existence of two types of lesions, tumors with good and poor prognosis, divided according to histological and surgical factors. The standard treatment for rectal adenocarcinoma T2N0M0 is TME without adjuvant therapy. In this type of adenocarcinoma, local surgery obtains the best results when complete pathological response has been achieved with previous chemoradiotherapy. The results with chemoradiotherapy and TEM are encouraging, but the scientific evidence remains limited at present. PMID:25206260

Sentinel node navigation surgery in gastric cancer: Current status  

PubMed Central

The theory behind using sentinel node mapping and biopsy in gastric cancer surgery, the so-called sentinel node navigation surgery, is to limit the extent of surgical tissue dissection around the affected organ and subsequently the accompanied morbidity. However, obstacles on the clinical correspondence of sentinel node navigation surgery in everyday practice have occasionally alleviated researchers’ interest on the topic. Only recently with the widespread use of minimally invasive surgical techniques, i.e., laparoscopic gastric cancer resections, surgical community’s interest on the topic have been unavoidably reflated. Double tracer methods appear superior compared to single tracer techniques. Ongoing research is now focused on the invention of new lymph node detection methods utilizing sophisticated technology such as infrared ray endoscopy, florescence imaging and near-infrared technology. Despite its notable limitations, hematoxylin/eosin is still the mainstay staining for assessing the metastatic status of an identified lymph node. An intra-operatively verified metastatic sentinel lymph node will dictate the need for further conventional lymph node dissection. Thus, laparoscopic resection of the gastric primary tumor combined with the appropriate lymph node dissection as determined by the process of sentinel lymph node status characterization represents an option for early gastric cancer. Patients with T3 or more advanced disease should still be managed conventionally with resection plus standard lymph node dissection. PMID:24976901

Robotic surgery in cancer care: opportunities and challenges.  

PubMed

Malignancy-associated mortality, decreased productivity, and spiritual, social and physical burden in cancer patients and their families impose heavy costs on communities. Therefore cancer prevention, early detection, rapid diagnosis and timely treatment are very important. Use of modern methods based on information technology in cancer can improve patient survival and increase patient and health care provider satisfaction. Robot technology is used in different areas of health care and applications in surgery have emerged affecting the cancer treatment domain. Computerized and robotic devices can offer enhanced dexterity by tremor abolition, motion scaling, high quality 3D vision for surgeons and decreased blood loss, significant reduction in narcotic use, and reduced hospital stay for patients. However, there are many challenges like lack of surgical community support, large size, high costs and absence of tactile and haptic feedback. A comprehensive view to identify all factors in different aspects such as technical, legal and ethical items that prevent robotic surgery adoption is thus very necessary. Also evidence must be presented to surgeons to achieve appropriate support from physicians. The aim of this review article is to survey applications, opportunities and barriers to this advanced technology in patients and surgeons as an approach to improve cancer care. PMID:24606422

Inguinal hernia developed after radical retropubic surgery for prostate cancer  

PubMed Central

Purpose In this retrospective study, we aimed to compare the clinical characteristics of inguinal hernia developed after radical retropubic surgery for prostate cancer to the hernia without previous radical prostatectomy. Methods Twenty-three patients (group A) who had radical retropubic surgery for prostate cancer underwent laparoscopic or open tension-free inguinal hernia repair from March 2007 to February 2011. Nine hundred and forty patients (group B) without previous radical retropubic surgery received laparoscopic or tension-free open hernia operation. Results Group A was older than group B (mean ± standard deviation, 69.6 ± 7.2 vs. 54.1 ± 16.1; P < 0.001). Right side (73.9%) and indirect type (91.3%) in group A were more prevalent than in group B (51.5% and 69.4%, respectively) with statistic significance (P = 0.020 and P = 0.023). The rate of laparoscopic surgery in group B (n = 862, 91.7%) was higher than in group A (n = 14, 64.3%, P < 0.001). In comparing perioperative variables between the two groups, operative time (49.4 ± 23.5 minutes) and hospital stay (1.9 ± 0.7 days) in group A were longer than in group B (38.9 ± 16.9, 1.1 ± 0.2; P = 0.046 and P < 0.001, respectively) and pain score at 7 days in group A was higher than in group B (3.1 ± 0.7 vs. 2.3 ± 1.0, P < 0.001). Postoperative recurrence rate was not significantly different between the two groups. Conclusion Inguinal hernia following radical retropubic surgery for prostate cancer was predominantly right side and indirect type with statistic significance compared to hernias without previous radical prostatectomy.

Choices in Surgery for Older Women with Breast Cancer  

PubMed Central

Summary Breast cancer is a major cause of mortality worldwide. As the population ages and life expectancy increases, the burden of cancer on health services will increase. Older patients with breast cancer are becoming more suitable for surgery; tailored surgical techniques and increasing healthy life expectancy alongside improved assessment of patients are aiding this trend. Surgery is also becoming a favoured treatment of personal choice for older patient with breast cancer. Evidence shows that surgery is almost always feasible for the older patient with outcomes (survival, progression, and recurrence rates) comparable to younger groups and superior to non-surgical treatments. We aim to describe the current status of surgery for the older patient with breast cancer, showing it is an option that should not be denied. Surgery should always be considered regardless of age, after evaluation of co-morbidities. PMID:24715825

Video-Assisted Thoracic Surgery Lobectomy: Results in Lung Cancer  

PubMed Central

Background The application of video-assisted thoracic surgery (VATS) in major pulmonary resections is still far from routine in most hospitals, even though the safety and technical feasibility of the procedure have by now been amply demonstrated. This paper reports on the surgical technique used by the authors for VATS lobectomy, on their experience of the procedure and on the results obtained. Methods A retrospective study was performed of all patients undergoing VATS lobectomy at the our Thoracic Surgery Department ,between 1993 and 2009.The clinical records of all patients were reviewed, and the following variables were noted for purposes of analysis: patient age and sex; clinical diagnosis; staging; date of surgery; type of surgery; conversion to conventional surgery and grounds for conversion; duration of surgery; intraoperative, postoperative and long-term complications; postoperative stay, final diagnosis and staging; and death rates. Results A total of 349 VATS lobectomies were performed over the study period (292 men, 57 women; mean age 59.7) The aetiology was non-small-cell lung carcinoma (NSCLC) in 313 patients and benign processes in 26;four patients had carcinoid tumours, and a further six required lobectomy due to metastases. The overall conversion rate was 9.4%. Mean duration of lobectomy was 148 minutes, and median duration 92 minutes. Mean postoperative was 3.9 days. The morbidity rate was 12.89 %, mostly involving minor complications. Perioperative mortality was 1.43%. There were no intraoperative deaths. The overall five-year survival rate for patients with NSCLC was 80.1%. Conclusions VATS lobectomy is a safe and technically-viable procedure that meets oncological criteria for lung-cancer surgery. Major pulmonary resection using VATS should be considered the procedure of choice for a number of benign processes and for early-stage bronchogenic carcinoma (T1-T2 N0 M0). PMID:22263014

Sentinel lymph node navigation surgery for early stage gastric cancer  

PubMed Central

We attempted to evaluate the history of sentinel node navigation surgery (SNNS), technical aspects, tracers, and clinical applications of SNNS using Infrared Ray Electronic Endoscopes (IREE) combined with Indocyanine Green (ICG). The sentinel lymph node (SLN) is defined as a first lymph node (LN) which receives cancer cells from a primary tumor. Reports on clinical application of SNNS for gastric cancers started to appear since early 2000s. Two prospective multicenter trials of SNNS for gastric cancer have also been accomplished in Japan. Kitagawa et al reported that the endoscopic dual (dye and radioisotope) tracer method for SN biopsy was confirmed acceptable and effective when applied to the early-stage gastric cancer (EGC). We have previously reported the usefulness of SNNS in gastrointestinal cancer using ICG as a tracer, combined with IREE (Olympus Optical, Tokyo, Japan) to detect SLN. LN metastasis rate of EGC is low. Hence, clinical application of SNNS for EGC might lead us to avoid unnecessary LN dissection, which could preserve the patient’s quality of life after operation. The most ideal method of SNNS should allow secure and accurate detection of SLN, and real time observation of lymphatic flow during operation. PMID:24914329

Surgical process improvement tools: defining quality gaps and priority areas in gastrointestinal cancer surgery  

PubMed Central

Background Surgery is a cornerstone of cancer treatment, but significant differences in the quality of surgery have been reported. Surgical process improvement tools (spits) modify the processes of care as a means to quality improvement (qi). We were interested in developing spits in the area of gastrointestinal (gi) cancer surgery. We report the recommendations of an expert panel held to define quality gaps and establish priority areas that would benefit from spits. Methods The present study used the knowledge-to-action cycle was as a framework. Canadian experts in qi and in gi cancer surgery were assembled in a nominal group workshop. Participants evaluated the merits of spits, described gaps in current knowledge, and identified and ranked processes of care that would benefit from qi. A qualitative analysis of the workshop deliberations using modified grounded theory methods identified major themes. Results The expert panel consisted of 22 participants. Experts confirmed that spits were an important strategy for qi. The top-rated spits included clinical pathways, electronic information technology, and patient safety tools. The preferred settings for use of spits included preoperative and intraoperative settings and multidisciplinary contexts. Outcomes of interest were cancer-related outcomes, process, and the technical quality of surgery measures. Conclusions Surgical process improvement tools were confirmed as an important strategy. Expert panel recommendations will be used to guide future research efforts for spits in gi cancer surgery. PMID:24764704

Is surgery always necessary in rectal cancer?  

PubMed

Rectal cancer is a major health problem around the world, representing about one-third of the total colorectal cancer cases. Because of its anatomical location, there is a higher risk of local recurrence, and treatment often requires a complex multidisciplinary approach which includes neoadjuvant radiotherapy, chemotherapy, and a radical surgical procedure that commonly leads to a permanent colostomy. The cure rate with this strategy is good, with some patients having no residual disease in the surgical specimen. While the prognosis for those patients is excellent, their quality of life is permanently compromised. In this article, we review risks and benefits of the standard treatment approach and compare standard treatment with alternative methods aimed at rectal preservation. PMID:25144282

Image-guided cancer surgery using near-infrared fluorescence  

PubMed Central

Paradigm shifts in surgery arise when surgeons are empowered to perform surgery faster, better, and/or less expensively. Optical imaging that exploits invisible near-infrared fluorescent light has the potential to improve cancer surgery outcomes while minimizing anesthesia time and lowering healthcare costs. Because of this, the last few years have witnessed an explosion of proof-of-concept clinical trials in the field. In this review, we introduce the concept of near-infrared fluorescence imaging for cancer surgery, review the clinical trial literature to date, outline the key issues pertaining to imaging system and contrast agent optimization, discuss limitations and leverage, and provide a framework for making the technology available for the routine care of cancer patients in the near future.

Chronic preoperative pain and psychological robustness predict acute postoperative pain outcomes after surgery for breast cancer  

PubMed Central

Background: Few epidemiological studies have prospectively investigated preoperative and surgical risk factors for acute postoperative pain after surgery for breast cancer. We investigated demographic, psychological, pain-related and surgical risk factors in women undergoing resectional surgery for breast cancer. Methods: Primary outcomes were pain severity, at rest (PAR) and movement-evoked pain (MEP), in the first postoperative week. Results: In 338 women undergoing surgery, those with chronic preoperative pain were three times more likely to report moderate to severe MEP after breast cancer surgery (OR 3.18, 95% CI 1.45–6.99). Increased psychological ‘robustness', a composite variable representing positive affect and dispositional optimism, was associated with lower intensity acute postoperative PAR (OR 0.63, 95% CI 0.48–0.82) and MEP (OR 0.71, 95% CI 0.54–0.93). Sentinel lymph node biopsy (SLNB) and intraoperative nerve division were associated with reduced postoperative pain. No relationship was found between preoperative neuropathic pain and acute pain outcomes; altered sensations and numbness postoperatively were more common after axillary sample or clearance compared with SLNB. Conclusion: Chronic preoperative pain, axillary surgery and psychological robustness significantly predicted acute pain outcomes after surgery for breast cancer. Preoperative identification and targeted intervention of subgroups at risk could enhance the recovery trajectory in cancer survivors. PMID:22850552

Healthcare Utilization in Women After Abdominal Surgery for Ovarian Cancer  

PubMed Central

Background Women undergoing surgery for ovarian cancer are severely ill and are high users of health services. Contributing to these increased utilization rates are the multiple modalities used to treat ovarian cancer, and the complications and side effects from those treatments. Objective To evaluate the effectiveness of an intervention provided by advanced practice nurses and a psychiatric consultation-liaison nurse on patients' self-report of health care utilization compared to an attention control intervention in women undergoing surgery for a suspected diagnosis of ovarian cancer. Method A two-group, experimental, longitudinal design was used to compare women who were assigned randomly to the intervention group or to an attention control group at baseline within 48 hours after surgery and 1, 3, and 6 months after surgery. Healthcare utilization was measured as the number of self-reported inpatient admissions and outpatient visits, including emergency room visits, oncology outpatient visits, and primary care visits. Nurse interventions consisted of 16 contacts: symptom management, counseling, education, direct nursing care, coordination of resources, and referrals. The attention control interventions consisted of 9 contacts that included instructions on use of a symptom management toolkit and strategies on how to manage symptoms. Results There were no differences in hospitalizations and oncology outpatient visits between the two groups. The main finding of this study was a significant difference in the number of primary care visits between the two groups. Women in the attention control group went to their primary care providers more often than the intervention group. The women who reported more visits also reported more depressive symptoms. In addition, a trend was found in the number of emergency room visits between the two groups. The intervention group visited the emergency room more often because the nurse instructed patients to go when they recognized symptoms that needed urgent care after hours. Discussion Women in the intervention group appropriately used the emergency room to manage their problems after hours, whereas more women in the attention control group reported significantly more primary care visits. These findings highlight the need for health care providers representing various disciplines to coordinate services across specialties, especially for women who have depressive symptoms.

Adherence to guidelines in gynecologic cancer surgery.  

PubMed

The purpose of this study is to review the available evidence documenting the prognostic role of adherence to guidelines in gynecologic cancers. A systematic review of the PubMed database using "guideline," "adherence," and "cancer" was carried out on February 25, 2014. Two thousand one hundred twenty-three publications were identified. Only publications addressing the question of adherence to recommendations regarding surgical care and multidisciplinary management of gynecologic cancers were selected. Six studies were identified in endometrial cancer, 4 in ovarian cancer, and none in cervical cancer. Adoption of guidelines is an effective tool for disease control and must consequently be considered as a process measure of quality cancer care. It is urgent to develop reliable and reproducible tools to assess adherence to guidelines based on level 1 evidence in gynecologic cancer then to carry out investigations to document the prognostic impact of compliance with guidelines. The time has come to include adherence to guidelines in quality assurance programs. PMID:25340292

Surgery for rectal cancer-what is on the horizon?  

PubMed

The management of rectal cancer has improved considerably in recent decades. Surgery remains the cornerstone of the treatment. However, the role of preoperative imaging has made it possible to optimize the treatment plan in rectal patients. Neoadjuvant treatment may be indicated in efforts to sterilize possible tumor deposits outside the surgical field, or may be used to downsize and downstage the tumor itself. The optimal sequence of treatment modalities can be determined by a multidisciplinary team, who not only use pretreatment imaging, but also review pathologic results after surgery. The pathologist plays a pivotal role in providing feedback about the success of surgery, i.e., the distance between the tumor and the circumferential resection margin, the quality of surgery, and the effect of neoadjuvant treatment. Registry and auditing of all treatment variables can further improve outcomes. In this century, rectal cancer treatment has become a team effort. PMID:24488545

Objectives: The objectives of this review are to summarize the current training modalities and assessment tools used in urological robotic surgery and to propose principles to guide the formation of a comprehensive robotics curriculum. Materials and Methods: The PUBMED database was systematically searched for relevant articles and their citations utilized to broaden our search. These articles were reviewed and summarized with a focus on novel developments. Results: A multitude of training modalities including didactic, dry lab, wet lab, and virtual reality have been developed. The use of these modalities can be divided into basic skills-based exercises and more advanced procedure-based exercises. Clinical training has largely followed traditional methods of surgical teaching with the exception of the unique development of tele-mentoring for the da Vinci interface. Tools to assess both real-life and simulator performance have been developed, including adaptions from Fundamentals of Laparoscopic Surgery and Objective Structured Assessment of Technical Skill, and novel tools such as Global Evaluative Assessment of Robotic Skills. Conclusions: The use of these different entities to create a standardized curriculum for robotic surgery remains elusive. Selection of training modalities and assessment tools should be based upon performance data-based validity and practical feasibility. Comparative assessment of different modalities (cross-modality validity) can help strengthen the development of common skill sets. Constant data collection must occur to guide continuing curriculum improvement. PMID:25097322

Re-examination of the standardization of colon cancer surgery  

PubMed Central

The standardization of colon cancer surgery has been an area of intense interest. The recent establishment of the complete mesocolic excision (CME) technique has defined the operative approach for colon cancer surgeries and enabled the collection of high-quality oncological specimens for histopathological evaluation. Standard for the Diagnosis and Treatment of Colorectal Cancer (2010), issued by the Ministry of Health of China, has provided legal bases for the treatment of colorectal cancers. However, certain confusions remain due to lack of detailed guidelines for operations. This raised the key question: “What is the standardized colon cancer surgery?” The present study re-examined the core ideas of General Rules for Clinical and Pathological Studies on Cancer of the Colon, Rectum and Anus (seventh edition) published by the Japanese Society for Cancer of the Colon and Rectum. CME-related studies published in English academic journals between April 2009 and July 2012 were surveyed and analysed. Several technical issues related to the requirement of R0 resection were analysed, including the theoretical basis for the safety range of bowel resection and the rational determination of the range of regional lymph node dissection.

Piloting a regional collaborative in cancer surgery using a “community of practice” model  

PubMed Central

Background Patients requiring assessment for cancer surgery encounter a complex series of steps in their cancer journey. Further complicating the process is the fact that care is often delivered in a fragmented, silo-based system. Isolated strategies to improve cancer outcomes within those systems have had inconsistent results. Methods A regional quality improvement collaborative was developed based on a community of practice (cop) platform, a hub-and-spoke infrastructure, and a regional steering committee linking cop improvement projects with affiliated hospitals and their strategic priorities. The cop provided an avenue for multidisciplinary teams to collect and compare their performance data and to institute regional standards through literature review, discussion, and consensus. Regional interdisciplinary teams developed a set of quality indicators linked to mutually agreed-upon care standards. A limited regional database supported feedback about performance against both provincial and regional standards. Results The cop approach helped to develop a multihospital collaboration that facilitated care quality improvements on a regional scale, with clinical outcomes of the improvements able to be measured. The 9 participating hospitals delivered cancer surgery in the specific disease sites according to practitioner-developed and provincially- or regionally-generated care standards and clinical pathways. Compliance with provincial evidence-based clinical guidelines improved (20% increase in 2010–2011 compared with 2006–2007). Other significant improvements included standardization and implementation of regional perioperative pathways in breast, colorectal, and prostate cancer disease sites; rectal cancer surgery centralization; increased use of sentinel lymph node biopsies in breast cancer surgery; and decreased positive surgical margin rates in prostate cancer. Conclusions Improved quality is likely a result of diverse confounding factors. The deliberately cultivated multihospital multidisciplinary cops have contributed to positive structural and functional change in cancer surgery in the region. This regional cop model has the potential to play an important role in the development of successful collaborations in care quality improvement. PMID:24523602

Laparoscopic gastric surgery for cancer: Where do we stand?  

PubMed Central

Gastric cancer poses a significant public health problem, especially in the Far East, due to its high incidence in these areas. Surgical treatment and guidelines have been markedly different in the West, but nowadays this debate is apparently coming to an end. Laparoscopic surgery has been employed in the surgical treatment of gastric cancer for two decades now, but with controversies about the extent of resection and lymphadenectomy. Despite these difficulties, the apparent advantages of the laparoscopic approach helped its implementation in early stage and distal gastric cancer, with an increase on the uptake for distal gastrectomy for more advanced disease and total gastrectomy. Nevertheless, there is no conclusive evidence about the laparoscopic approach yet. In this review article we present and analyse the current status of laparoscopic surgery in the treatment of gastric cancer. PMID:25339815

Minimally-invasive surgery, or video-assisted surgery, includes laparoscopy, retroperitoneoscopy and thoracoscopy, can be used for diagnosis (biopsies) and treatment (resections) in various malignant solid tumours in children. Potential advantages of MIS techniques include a decreased parietal trauma (cosmetic benefit, bowel adhesions) and less postoperative discomfort (postoperative pain, analgesics requirement, postoperative ileus, length of hospital stay). Main indications of MIS techniques are represented by diagnostic biopsies (mediastinal or lung tumors, retroperitoneal extrarenal masses), resection of the primary tumor in thoracic and abdominal neuroblastic tumors and in post-treatment residual mass in lymphoma.

Intuitively, breast tissue mass should be directly related to a woman'srisk of breast cancer, simply because having more cells at risk would seem toincrease the potential for malignant transformation. However, studiesattempting to link breast size with breast cancer risk have beeninconsistent. Limitations include crude measures of breast size, theinability to distinguish glandular from adipose tissue, and the confoundinginfluence of co-factors

Definition of Compartment Based Radical Surgery in Uterine Cancer--Part I: Therapeutic Pelvic and Periaortic Lymphadenectomy by Michael H?ckel Translated to Robotic Surgery  

PubMed Central

Objective. To define compartment based therapeutic pelvic and periaortic lymphadenectomy in cervical and endometrial cancer. Compartment based oncologic surgery appears to be favorable for patients in terms of radicality as well as complication rates, and the same appears to be true for robotic surgery. We describe a method of robotically assisted compartment based lymphadenectomy step by step in uterine cancer and demonstrate feasibility data from 35 patients. Methods. Patients with the diagnosis of endometrial (n = 16) or cervical (n = 19) cancer were included. Patients were treated by rTMMR (robotic total mesometrial resection) or rPMMR (robotic peritoneal mesometrial resection) and pelvic or pelvic/periaortic rtLNE (robotic therapeutic lymphadenectomy) with cervical cancer FIGO IB-IIA or endometrial cancer FIGO I-III. Results. No transition to open surgery was necessary. Complication rates were 13% for endometrial cancer and 21% for cervical cancer. Within follow-up time median (22/20) month we noted 1 recurrence of cervical cancer and 2 endometrial cancer recurrences. Conclusions. We conclude that compartment based rtLNE is a feasible and safe technique for the treatment of uterine cancers and is favorable in aspects of radicality and complication rates. It should be analyzed in multicenter studies with extended followup on the basis of the described technique. PMID:23589777

Salvage surgery after unsuccessful radiotherapy in early glottic cancer.  

PubMed

Surgery is the main therapeutic option to control recurrent laryngeal cancer after radiotherapy (RT) relapse. Most RT-recurred cancer is treated aggressively; although, conservative laryngeal surgery was attempted in selected cases. Here, we report our experiences with salvage laryngeal surgery for early glottic cancers that did not respond to RT. We analyzed files from 1980 to 2006 and selected 173 patients surgically treated for a RT-failed early glottic carcinoma (stage I-II according to 2010 TNM: 114 T1N0, 59 T2N0). Among them, 47 patients (27%) underwent a salvage partial laryngectomy (SPL) and 126 (73%) had a salvage total laryngectomy (STL). When compared with initial T staging, we found 61% of lesions were up-staged, 31% had the same staged lesion, and only 8% were down-staged (according to rTNM). No statistically significant differences were found in terms of disease-free survival and overall survival when SPL and STL patients were compared. Univariate analysis showed that T, rT, and rTNM were prognostic factors for overall survival (p = 0.045, p = 0.028, and p = 0.037, respectively); yet, these significances were lost in multivariate analysis. Our results suggest that salvage surgery is feasible in most cases of RT-recurred early glottic cancer; although, a conservative approach achieves good oncological and functional results only in select RT-recurred patients.

Colonic Stent as Bridge to Surgery in Patients with Obstructive Left-Sided Colon Cancer  

PubMed Central

Objective: We assessed the optimal time interval between endoscopic stenting and subsequent surgery in patients with obstructive left-sided colon cancer. Methods: We reviewed the medical records of patients who underwent endoscopic colonic stenting for obstructive left-sided colon cancer between January 2009 and January 2012. Patients who had successful endoscopic intervention as a bridge to surgery were included in the study. Other variables studied were the duration between endoscopic stenting and surgery, the reobstruction rate, the stoma creation rate, the anastomotic leak rate, and the in-hospital mortality rate. Results: The medical records of 53 patients who underwent endoscopic stenting for obstructive left-sided colon cancer were reviewed, and 43 were included in the study. The median duration between endoscopic stenting and surgery was 7 days (range, 5–33). Conclusion: A median duration of 7 to 9 days after endoscopic stenting in patients with obstructive left-sided colon cancer is enough time to subsequently perform a safe surgical procedure. Extending this duration may expose the patient to the risk of reobstruction and emergency surgery.

[Organ preservation surgery in pharyngolaryngeal cancer].  

PubMed

Organ preservation surgery is a reasonable name for these types of techniques because it accurately describes the postoperative outcome, which is preservation of the quintessential laryngeal functions: swallowing, respiration without a permanent stoma and speech. In response to the common use of total laryngectomy, the non-surgical approaches have often been referred to as organ preservation strategies. In many institutions, it appears that there are organ preservation strategies and then there is surgery. In our opinion there are both non surgical organ preservation strategies and surgical organ preservation strategies. The key is that in both approaches the goal is to spare the functions of the larynx. In both, the work-ups are very important to analyse 3-dimensional extent of the lesion by nasofibroscopy (laryngeal mobilities), endoscopy and radiology. Organ preservation surgical approach allowed to save the use of radiotherapy for the management of various metachronous second primary tumours. PMID:17137252

Surgery remains the cornerstone in the multidisciplinary treatment of colon and rectal cancer. Many diagnostic, technical, and adjuvant therapies are known to impact the immediate and long-term oncologic results. Guidelines for appropriate cancer-specific management of colorectal cancer should be adhered to so as to optimize the oncologic outcomes. Similarly, patient-specific surgical outcomes are also linked to many systems-based factors, such as appropriate use of perioperative antibiotics, venous thromboembolism prophylaxis, and avoidance of surgical complications.

Combination of surgery and radiation in the treatment of cancer. A review  

SciTech Connect

Although radiation and surgery have been combined for the treatment of cancer in humans and animals since the 1920s, little has been written about the methods of combining radiation and surgery and the efficacy of this combination for the treatment of animal tumors. This article reviews the rationale for combining radiation and surgery for the treatment of cancer and the ways in which these two modalities can be combined with emphasis placed on the advantages and disadvantages of preoperative and postoperative radiotherapy. The role of preoperative and postoperative irradiation for the treatment of various animal tumors is discussed. Directions for future clinical trials are pointed out. Finally, the importance of surgeons and radiation oncologists communicating with each other and participating in cooperative treatment methods is stressed. 36 references.

Inferior oncological prognosis of surgery without oral chemotherapy for stage III colon cancer in clinical settings  

PubMed Central

Background Cancer patients not admissible for adjuvant chemotherapy are generally at high risk of considerably inferior prognosis. The aim of this retrospective study was to evaluate poorer survival without administration of oral adjuvant chemotherapy of stage III colon cancer patients in clinical settings. Methods Between April 2007 and September 2011, 259 patients with stage III colon cancer who underwent curative surgery were retrospectively assigned to the adjuvant chemotherapy group of 171 patients (66%) and the surgery alone group of 88 patients. Oral fluorouracil (5-FU) derivatives used in adjuvant chemotherapy, such as oral uracil and tegafur plus leucovorin (UFT/LV) or capecitabine, were the most commonly used. Results The 3-year relapse-free survival (RFS) rates were 74.9% for all cases, 58.3% for the surgery alone group, and 83.4% for the adjuvant chemotherapy group (P?=?0.0001). The chemotherapy group was associated with a dramatic improvement in survival for stage IIIB (surgery alone 57.7% versus adjuvant chemotherapy 83.9%; P?=?0.0001) and stage IIIC (surgery alone 18.2% versus adjuvant chemotherapy 57.3%; P?=?0.006) patients. There was a significant difference in the overall recurrence rate between groups (surgery alone 35.2% versus adjuvant chemotherapy 18.1%; P?=?0.002). Multivariate analysis identified adjuvant therapy as an independent predictive factor of reduced recurrence (hazard ratio (HR): 3.231; P?=?0.004) and improved RFS (HR: 2.653; P?=?0.001). Conclusion In clinical settings, adjuvant therapy was the only significant prognostic factor of survival. Since many patients prefer not to receive chemotherapy, it is critical to inform stage III colon cancer patients that chemotherapy raises their chances of survival by three-fold compared with curative surgery alone.

Intraoperative image-guided surgery for ovarian cancer  

PubMed Central

Approximately two thirds of the ovarian cancer is diagnosed at late stage with peritoneal seeding. The most important prognostic factor is the residual tumor size after surgery. The better survival outcome from minimizing tumor has been established well from several institutional reports, clinical trials for chemotherapy, and meta-analyses. The current standard treatment for such advanced ovarian cancer is to resect all visible and palpable ovarian cancer as much as possible and postoperative chemotherapy. But, even after complete resection of all visible and palpable tumors, a significant percentage of the patients have recurrence usually in the peritoneal cavity in advanced ovarian cancer. Recurrence likely stems from microscopic residual tumor not resected at time of the initial surgery. Currently, advanced technology for intraoperative tumor detection has been reported. Although the current clinical outcome is at an early stage definitively, clinical benefit could be expected from the future in-depth basic research and clinical trials in this area. If all residual microscopic disease, especially chemotherapy-resistant cancer cells, could be removed or treated using new technology, groundbreaking advance for treating ovarian cancer will be realized.

Optical coherence tomography in guided surgery of GI cancer  

NASA Astrophysics Data System (ADS)

Optical Coherence Tomography (OCT) is a new high spatial resolution, real-time optical imaging modality, known from prior pilot studies for its high sensitivity to invasive cancer. We reported our results in an OCT feasibility study for accurate determination of the proximal border for esophageal carcinoma and the distal border for rectal carcinoma. The OCT study enrolled 19 patients with rectal adenocarcinoma and 24 patients with distal esophageal carcinoma (14 squamous cell carcinomas, 10 adenocarcinomas). During pre-surgery planning endoscopy we performed in vivo OCT imaging of the tumor border at four dial clock axes (12, 3, 6 and 9 o"clock). The OCT border then was marked by an electrocoagulator, or by a methylene blue tattoo. A cold biopsy (from the esophagus) was performed at visual and OCT borders and compared with visual and OCT readings. 27 post-surgery excised specimens were analyzed. OCT borders matched the histopathology in 94% cases in the rectum and 83.3% in the esophagus. In the cases of a mismatch between the OCT and histology borders, a deep tumor invasion occurred in the muscle layer (esophagus, rectum). Because of its high sensitivity to mucosal cancer, OCT can be used for pre-surgery planning and surgery guidance of the proximal border for esophageal carcinoma and the distal border for rectal carcinoma. However, deep invasion in the rectum or esophageal wall has to be controlled by alternative diagnostic modalities.

[Rational approach of antibioprophylaxis: systematic review in ENT cancer surgery].  

PubMed

In head and neck cancer surgery antibiotic prophylaxis is effective in reducing the incidence of surgical site infections (SSI). However, controversies between antibiotic prophylaxis and curative antibiotic therapy exist, particularly when complex and decaying surgeries are performed in risky underlying conditions, with a risk of persisting salivary effusion in the postoperative period, or in the case of reconstruction with myo-cutaneous flaps. We have performed a systematic review of the literature according to PRISMA recommendations to answer the following questions: indications for antibiotic prophylaxis and curative antibiotic therapy, optimal duration, and choice of antibiotics for prophylaxis in head and neck cancer surgery. Literature analysis allows to conclude that patients undergoing Altemeier classes 2 and 3 surgical procedures should receive perioperative antibiotic prophylaxis restricted to the first 24 postoperative hours. No benefit has been shown with its extension beyond these 24 hours. The most adapted combinations of antibiotics in this setting are "amoxicillin+clavulanic acid" and "clindamycin+gentamicin". However, the level of evidence regarding the most decaying surgeries with high risk of SSI is low, making it necessary to perform new high-powered randomized trials in these patients. Eventually, it should be noted that antibiotic prophylaxis should be an integral part of SSI preventive measures, including application of hygiene measures, and postoperative monitoring of SSI clinical signs.

Oncoplastic surgery in the treatment of breast cancer  

PubMed Central

Advances in reconstructive breast surgery with new materials and techniques now allow us to offer our patients the best possible cosmetic results without the risks associated with oncological control of the disease. These advances, in both oncological and plastic surgery, have led to a new specialisation, namely oncoplastic breast surgery, which enables us to undertake large resections and, with advance planning, to prevent subsequent deformities. This is particularly important when more than 30% of the breast volume is removed, as it allows us to obtain precise information for conservative surgery according to the site of the lesion, and also allows us to set the boundary between conservative surgery and mastectomy. Given the existence of new alloplastic materials and new reconstructive techniques, it is essential for our patients that surgeons involved in breast cancer treatment are trained in both the oncological as well as the reconstructive and aesthetic fields, to enable them to provide the best loco-regional treatment with the best cosmetic results.

Molecular imaging for cancer diagnosis and surgery.  

PubMed

Novel molecular imaging techniques have the potential to significantly enhance the diagnostic and therapeutic approaches for cancer treatment. For solid tumors in particular, novel molecular enhancers for imaging modalities such as US, CT, MRI and PET may facilitate earlier and more accurate diagnosis and staging which are prerequisites for successful surgical therapy. Enzymatically activatable "smart" molecular MRI probes seem particularly promising because of their potential to image tumors before and after surgical removal without re-administration of the probe to evaluate completeness of surgical resection. Furthermore, the use of "smart" MR probes as part of screening programs may enable detection of small tumors throughout the body in at-risk patient populations. Dual labeling of molecular MR probes with fluorescent dyes can add real time intraoperative guidance facilitating complete tumor resection and preservation of important structures. A truly theranostic approach with the further addition of therapeutic agents to the molecular probe for adjuvant therapy is conceivable for the future. PMID:24064465

Definition of compartment-based radical surgery in uterine cancer: radical hysterectomy in cervical cancer as 'total mesometrial resection (TMMR)' by M H?ckel translated to robotic surgery (rTMMR)  

PubMed Central

Background Radical hysterectomy has been developed as a standard treatment in Stage I and II cervical cancers with and without adjuvant therapy. However, there have been several attempts to standardize the technique of radical hysterectomy required for different tumor extension with variable success. Total mesometrial resection as ontogenetic compartment-based oncologic surgery - developed by open surgery - can be standardized identically for all patients with locally defined tumors. It appears to be promising for patients in terms of radicalness as well as complication rates. Robotic surgery may additionally reduce morbidity compared to open surgery. We describe robotically assisted total mesometrial resection (rTMMR) step by step in cervical cancer and present feasibility data from 26 patients. Methods Patients (n = 26) with the diagnosis of cervical cancer were included. Patients were treated by robotic total mesometrial resection (rTMMR) and pelvic or pelvic/periaortic robotic therapeutic lymphadenectomy (rtLNE) for FIGO stage IA-IIB cervical cancer. Results No transition to open surgery was necessary. No intraoperative complications were noted. The postoperative complication rate was 23%. Within follow-up time (mean: 18 months) we noted one distant but no locoregional recurrence of cervical cancer. There were no deaths from cervical cancer during the observation period. Conclusions We conclude that rTMMR and rtLNE is a feasible and safe technique for the treatment of compartment-defined cervical cancer. PMID:23972128

Association Between Serotonin Transport Polymorphisms and Postdischarge Nausea and Vomiting in Women Following Breast Cancer Surgery  

PubMed Central

Purpose/Objectives To examine the association of the serotonin transport gene and postdischarge nausea and vomiting (PDNV) in women following breast cancer surgery. Design A cross-sectional study. Setting A comprehensive cancer center in Pittsburgh, PA. Sample 80 post-menopausal women treated surgically for early-stage breast cancer. Methods Data were collected using standardized instruments after surgery but before the initiation of chemotherapy. Blood or saliva were used for DNA extraction and analyzed following standardized protocols. Data were analyzed using descriptive statistics and logistic regression. Main Research Variables Serotonin transport gene (SLC6A4), nausea, vomiting, pain, and anxiety. Findings Women who inherited the LA/LA genotypes were at greater risk for nausea and vomiting when compared to women who carried any other combination of genotypes. Twenty-one percent of women reported nausea and vomiting an average of one month following surgery and prior to initiation of adjuvant therapy. Those women who experienced PDNV reported significantly higher anxiety and pain scores. Conclusions Findings of this study suggest that variability in the genotypes of the serotonin transport gene may help to explain the variability in PDNV in women following breast cancer surgery and why 20%–30% of patients do not respond to antiemetic medications. Implications for Nursing Nurses need to be aware that women who do not experience postoperative nausea and vomiting following surgery for breast cancer continue to be at risk for PDNV long after they have been discharged from the hospital, and this frequently is accompanied by pain and anxiety.

Segmental thoracic spinal has advantages over general anesthesia for breast cancer surgery  

PubMed Central

Background: Thoracic spinal anesthesia has been used for laparoscopic cholecystectomy and abdominal surgeries, but not in breast surgery. The present study compared this technique with general anesthesia in breast cancer surgeries. Materials and Methods: Forty patients were enrolled in this comparative study with inclusion criteria of ASA physical status I-III, primary breast cancer without known extension beyond the breast and axillary nodes, scheduled for unilateral mastectomy with axillary dissection. They were randomly divided into two groups. The thoracic spinal group (S) (n = 20) underwent segmental thoracic spinal anesthesia with bupivacaine and fentanyl at T5-T6 interspace, while the other group (n = 20) underwent general anesthesia (G). Intraoperative hemodynamic parameters, intraoperative complications, postoperative discharge time from post-anesthesia care unit (PACU), postoperative pain and analgesic consumption, postoperative adverse effects, and patient satisfaction with the anesthetic techniques were recorded. Results: Intraoperative hypertension (20%) was more frequent in group (G), while hypotension and bradycardia (15%) were more frequent in the segmental thoracic spinal (S) group. Postoperative nausea (30%) and vomiting (40%) during PACU stay were more frequent in the (G) group. Postoperative discharge time from PACU was shorter in the (S) group (124 ± 38 min) than in the (G) group (212 ± 46 min). The quality of postoperative analgesia and analgesic consumption was better in the (S) group. Patient satisfaction was similar in both groups. Conclusions: Segmental thoracic spinal anesthesia has some advantages when compared with general anesthesia and can be considered as a sole anesthetic in breast cancer surgery with axillary lymph node clearance.

Transoral robotic surgery and oropharyngeal cancer: a literature review.  

PubMed

The incidence of head and neck squamous cell carcinoma has risen steadily over the past decade due to the increase in cancers associated with the human papillomavirus (HPV). The prognosis for the treatment of this type of cancer with radiotherapy and chemoradiotherapy is good. However, because these treatments can have detrimental effects on organ function and quality of life, researchers are looking into transoral robotic surgery (TORS) as a possible alternate therapy. TORS might have a positive effect on postoperative function and quality of life for cancer survivors. The aim of this review is to report on the current situation regarding the treatment of oropharyngeal cancer with TORS, with a focus on the long-term oncologic and functional outcomes of this strategy. The articles cited in this review were selected from the PubMed and MEDLINE database. They contain study results pertaining to TORS implementation, complications, oncologic and functional outcomes, and the implications of HPV-associated cancer. We found that while TORS has some clear advantages and strengths and almost certainly a permanent place in future treatment, further research is necessary to correctly evaluate the role it will play in the complete management of oropharyngeal cancer.

Safety and feasibility of video-assisted thoracoscopic surgery for stage IIIA lung cancer  

PubMed Central

Objective The current study was prospectively designed to explore the application of video-assisted thoracoscopic surgery (VATS) radical treatment for patients with stage IIIA lung cancer, with the primary endpoints being the safety and feasibility of this operation and the second endpoints being the survival and complications after the surgery. Methods A total of 51 patients with radiologically or mediastinoscopically confirmed stage IIIA lung cancer underwent VATS radical treatment, during which the standard pulmonary lobectomy and mediastinal lymph node dissection were performed after pre-operative assessment. The operative time, intraoperative blood loss/complications, postoperative recovery, postoperative complications, and lymph node dissection were recorded and analyzed. This study was regarded as successful if the surgical success rate reached 90% or higher. Results A total of 51 patients with non-small cell lung cancer (NSCLC) were enrolled in this study from March 2009 to February 2010. The median post-operative follow-up duration was 50.5 months. Of these 51 patients, 41 (80.4%) had N2 lymph node metastases. All patients underwent the thoracoscopic surgeries, among whom 50 (98%) received pulmonary lobectomy and mediastinal lymph node dissection completely under the thoracoscope, 6 had their incisions extended to about 6 cm due to larger tumor sizes, and 1 had his surgery performed using a 12 cm small incision for handling the adhesions between lymph nodes and blood vessels. No patient was converted to conventional open thoracotomy. No perioperative death was noted. One patient received a second surgery on the second post-operative day due to large drainage (>1,000 mL), and the postoperative recovery was satisfactory. Up to 45 patients (88.2%) did not suffer from any perioperative complication, and 6 (11.8%) experienced one or more complications. Conclusions VATS radical treatment is a safe and feasible treatment for stage IIIA lung cancer. PMID:25232214

Patient educational needs of patients undergoing surgery for lung cancer.

There often exists a discrepancy between the information health care professionals (HCPs) provide to patients in preoperative teaching sessions and the information patients perceive as important. This study's purpose was to determine what information patients undergoing a lung cancer surgical resection wanted to learn before and after their surgery and also to uncover the information HCPs currently provide to these patients. Ten patients were interviewed preoperatively and postoperatively, and eleven HCPs involved in both their preoperative and postoperative care were interviewed. Emerging themes were noted. Patients reported that the most helpful aspects of the preoperative education included surgical details and the importance of physiotherapy, including exercises. Postoperatively, patients wished they had known more about postoperative pain. HCPs provided information that they felt prepared, informed and empowered their patients. Overall, patients expressed satisfaction with the information they received; they felt prepared for their surgery but not for postoperative pain control. PMID:24756546

Relation of Surgeon and Hospital Volume to Processes and Outcomes of Colorectal Cancer Surgery  

PubMed Central

Background: Greater hospital volume has been associated with lower mortality after colorectal cancer surgery. The contribution of surgeon volume to processes and outcomes of care is less well understood. We assessed the relation of surgeon and hospital volume to postoperative and overall mortality, colostomy rates, and use of adjuvant radiation therapy. Methods: From the California Cancer Registry, we studied 28,644 patients who underwent surgical resection of stage I to III colorectal cancer during 1996 to 1999 and were followed up to 6 years after surgery to assess 30-day postoperative mortality, overall long-term mortality, permanent colostomy, and use of adjuvant radiation therapy. Results: Across decreasing quartiles of hospital and surgeon volume, 30-day postoperative mortality ranged from 2.7% to 4.2% (P<0.001). Adjusting for age, stage, comorbidity, and median income among patients with colorectal cancer who survived at least 30 days, patients in the lowest quartile of surgeon volume had a higher adjusted overall mortality rate than those in the highest quartile (hazard ratio, 1.16; 95% confidence interval, 1.09–1.24), as did patients in the lowest quartile of hospital volume relative to those treated in the highest quartile (hazard ratio, 1.11; 95% confidence interval, 1.05–1.19). For rectal cancer, adjusted colostomy rates were significantly higher for low-volume surgeons, and the use of adjuvant radiation therapy was significantly lower for low-volume hospitals. Conclusions: Greater surgeon and hospital volumes were associated with improved outcomes for patients undergoing surgery for colorectal cancer. Further study of processes that led to these differences may improve the quality of colorectal cancer care. PMID:17122626

Comparison of Survival Rate in Primary Non-Small-Cell Lung Cancer Among Elderly Patients Treated With Radiofrequency Ablation, Surgery, or Chemotherapy  

SciTech Connect

Purpose: We retrospectively compared the survival rate in patients with non-small-cell lung cancer (NSCLC) treated with radiofrequency ablation (RFA), surgery, or chemotherapy according to lung cancer staging. Materials and Methods: From 2000 to 2004, 77 NSCLC patients, all of whom had WHO performance status 0-2 and were >60 years old, were enrolled in a cancer registry and retrospectively evaluated. RFA was performed on patients who had medical contraindications to surgery/unsuitability for surgery, such as advanced lung cancer or refusal of surgery. In the RFA group, 40 patients with inoperable NSCLC underwent RFA under computed tomography (CT) guidance. These included 16 patients with stage I to II cancer and 24 patients with stage III to IV cancer who underwent RFA in an adjuvant setting. In the comparison group (n = 37), 13 patients with stage I to II cancer underwent surgery; 18 patients with stage III to IV cancer underwent chemotherapy; and 6 patients with stage III to IV cancer were not actively treated. The survival curves for RFA, surgery, and chemotherapy in these patients were calculated using Kaplan-Meier method. Results: Median survival times for patients treated with (1) surgery alone and (2) RFA alone for stage I to II lung cancer were 33.8 and 28.2 months, respectively (P = 0.426). Median survival times for patients treated with (1) chemotherapy alone and (2) RFA with chemotherapy for stage III to IV cancer were 29 and 42 months, respectively (P = 0.03). Conclusion: RFA can be used as an alternative treatment to surgery for older NSCLC patients with stage I to II inoperable cancer and can play a role as adjuvant therapy with chemotherapy for patients with stage III to IV lung cancer.

Impact of breast cancer surgery on angiogenesis circulating biomarkers: a prospective longitudinal study  

PubMed Central

Background Debate about the potential effects that surgery might have on cancer cells dormancy and angiogenesis prompted us to investigate the impact of breast surgery on circulating angiogenesis modulating gene transcripts and proteins. Methods Blood samples from 10 female patients diagnosed with breast cancer and 6 with fibroadenoma were collected before surgery and post-operatively on days 3 and 7 (breast cancer patients only). A set of 84 angiogenesis-associated transcripts were assessed using quantitative PCR arrays, and circulating protein levels (vascular endothelial growth factor A (VEGFA), IL8 and fibroblast growth factor 2 (FGF2) were measured using ELISA in the same samples. The results were investigated against clinicopathological data and patient outcome. Results Plasma levels of VEGFA and IL8 after surgery were significantly elevated in the breast cancer group compared to the control group (P = 0.038 and P = 0.021, respectively). In the cohort of breast cancer patients, VEGFA increased on day 3 (P = 0.038) and declined on day 7 (P= 0.017), while IL8 did not change on day 3 but showed a significant decline on day 7 (P = 0.02). FGF2 levels did not change significantly over time. Regarding gene transcripts, we detected upregulation of a significant number of angiogenesis-specific genes in patients with breast cancer versus controls: sphingosine kinase 1(SPHK1), epidermal growth factor (EGF), vascular endothelial growth factor C (VEGFC), neuropilin 1 (NRP1), fibroblast growth factor (FGF1), laminin alpha 5 (LAMA5), collagen type IV alpha 3 (COL4A3), IL8, ephrin B2 (EFNB2), ephrin A3 (EFNA3), tyrosine endothelial kinase (TEK), integrin beta 3 (ITGB3), AKT1, thrombospondin 1 (THBS1), chemokine (C-C motif) ligand 11 (CCL11) and TIMP metallopeptidase inhibitor 3 (TIMP3). Surgery induced an altered expression in several keygenes in breast cancer patients. We identified an upregulation of COL4A3 and downregulation of chemokine (C-X-C motif) ligand 9 (CXCL9), EGF, FGF1, Kinase insert domain receptor (KDR), Placental growth factor (PGF), TIMP3 and VEGFC. Conclusion Breast cancer patients have a different expression profile of circulating angiogenesis biomarkers compared to patients with fibroadenoma. Moreover, mastectomy promotes a transient increase of VEGFA and a shift in the expression patterns of a broad panel of angiogenesis-related circulating gene transcripts. PMID:23981902

Comparison of Robotic Surgery with Laparoscopy and Laparotomy for Treatment of Endometrial Cancer: A Meta-Analysis  

PubMed Central

Purpose To compare the relative merits among robotic surgery, laparoscopy, and laparotomy for patients with endometrial cancer by conducting a meta-analysis. Methods The MEDLINE, Embase, PubMed, Web of Science, and Cochrane Library databases were searched. Studies clearly documenting a comparison between robotic surgery and laparoscopy or between robotic surgery and laparotomy for endometrial cancer were selected. The outcome measures included operating time (OT), number of complications, length of hospital stay (LOHS), estimated blood loss (EBL), number of transfusions, total lymph nodes harvested (TLNH), and number of conversions. Pooled odds ratios and weighted mean differences with 95% confidence intervals were calculated using either a fixed-effects or random-effects model. Results Twenty-two studies were included in the meta-analysis. These studies involved a total of 4420 patients, 3403 of whom underwent both robotic surgery and laparoscopy and 1017 of whom underwent both robotic surgery and laparotomy. The EBL (p?=?0.01) and number of conversions (p?=?0.0008) were significantly lower and the number of complications (p<0.0001) was significantly higher in robotic surgery than in laparoscopy. The OT, LOHS, number of transfusions, and TLNH showed no significant differences between robotic surgery and laparoscopy. The number of complications (p<0.00001), LOHS (p<0.00001), EBL (p<0.00001), and number of transfusions (p?=?0.03) were significantly lower and the OT (p<0.00001) was significantly longer in robotic surgery than in laparotomy. The TLNH showed no significant difference between robotic surgery and laparotomy. Conclusions Robotic surgery is generally safer and more reliable than laparoscopy and laparotomy for patients with endometrial cancer. Robotic surgery is associated with significantly lower EBL than both laparoscopy and laparotomy; fewer conversions but more complications than laparoscopy; and shorter LOHS, fewer complications, and fewer transfusions but a longer OT than laparoscopy. Further studies are required. PMID:25259856

Fertility-Sparing Surgery for Early-Stage Cervical Cancer  

PubMed Central

Nowadays cervical cancer is diagnosed in many women who still want to have children. This led to the need to provide fertility-sparing treatments. The main goal is to maintain reproductive ability without decreasing overall and recurrence-free survival. In this article, we review data on procedures for fertility preservation, namely, vaginal and abdominal trachelectomy, less invasive surgery and neoadjuvant chemotherapy. For each one, oncological and obstetrical outcomes are analyzed. Comparing to traditionally offered radical hysterectomy, the overall oncologic safety is good, with promising obstetrical outcomes.

Sigmoid volvulus after laparoscopic surgery for sigmoid colon cancer.  

PubMed

We report the first case of sigmoid volvulus after laparoscopic surgery for sigmoid colon cancer. The patient is a 75-year-old man who presented with the sudden onset of severe abdominal pain. He had undergone laparoscopic sigmoidectomy for cancer 2 years before presentation. CT scan showed a distended sigmoid colon with a mesenteric twist, or "whirl sign." Colonoscopy showed a mucosal spiral and luminal stenosis with dilated sigmoid colon distally and ischemic mucosa. The diagnosis of ischemic colonic necrosis due to sigmoid volvulus was established. Resection of the necrotic sigmoid colon was performed and a descending colon stoma was created. A long remnant sigmoid colon and chronic constipation may contribute to the development of sigmoid volvulus after laparoscopic sigmoidectomy. Prompt diagnosis is essential for adequate treatment, and colonoscopy aids in the diagnosis of ischemic changes in patients without definitive findings of a gangrenous colon. PMID:23879414

Surreptitious surgery on Long Island Sound: The oral cancer surgeries of President Grover Cleveland.  

PubMed

Grover Cleveland rose from being the mayor of Buffalo to the governor of New York to the president of the United States. At the start of Cleveland's second term as president, the nation was involved in a severe financial crisis, the extent of which was not known by the general public. President Cleveland was to make a strong appeal to Congress in the coming months to repeal the Sherman Silver Purchase Act of 1890. He thought this would set the nation on the road to fiscal recovery. However, his vice president, Adlai Stevenson, strongly opposed repeal of the Sherman Act. Prior to scheduling his appearance before Congress, President Cleveland noticed a rough spot on his palate. A biopsy confirmed that it was cancer, and it was determined that surgery was needed. Cleveland and his advisors thought the nation would be thrown into a panic if the President's health did not remain a secret. A surgical team, which included a dentist, performed the surgery in secrecy while traveling aboard a yacht. A prosthetic obturator was fabricated by a New York prosthodontist to close the surgical defect. Cleveland recovered well, made a forceful speech before Congress, had the Sherman Act repealed and lived without a recurrence of his oral cancer for the rest of his life. The public remained unaware, for the most part, of the gravity of President Cleveland's health for decades. PMID:20359065

Incidence of cancer following bariatric surgery: systematic review and meta-analysis.  

PubMed

Obesity is linked to the development of cancer. Previous studies have suggested that there is a relationship between bariatric surgery and reduced cancer risk. Data sources were from Medline, Embase, and Cochrane Library. From 951 references, 13 studies met the inclusion criteria (54,257 participants). In controlled studies, bariatric surgery was associated with a reduction in the risk of cancer. The cancer incidence density rate was 1.06 cases per 1000 person-years within the surgery groups. In the meta-regression, we found an inverse relationship between the presurgical body mass index and cancer incidence after surgery (beta coefficient -0.2, P?surgery is associated with reduced cancer risk in morbidly obese people. However, considering the heterogeneity among the studies, conclusions should be drawn with care. PMID:24817500

[Sentinel node concept and its application for cancer surgery].  

PubMed

The sentinel node is the first lymph node that drains a primary tumor. A negative sentinel lymph node accurately predicts the absence of metastasis to any other regional lymph nodes. A higher rate of feasibility, sensitivity, specificity, and diagnostic accuracy in sentinel lymph node mapping has been demonstrated of cancer of the breast, penis, and vulva and in malignant melanoma. Intraoperative endoscopic lymphatic mapping, which we developed for gastric cancer in 1994, was also useful in accurately predicting nodal status in 163 early-stage gastric cancer patients: the rate of sensitivity, specificity, and accuracy was 91%, 100%, and 98%, respectively. Therefore if the sentinel lymph node biopsy is free of metastasis, limited surgery such as wedge resection, segmental resection, pylorus-preserving gastrectomy, or proximal gastrectomy is indicated. The tumor-free sentinel lymph node allows dissection of regional lymph nodes to be avoided and results in an improved quality of life in postoperative patients. In addition, sentinel lymph node biopsy has the advantages of enhancing staging accuracy, detecting micrometastases, and identifying variations in the regional lymphatic basin. Further progress may change the mode of nodal dissection and the indications for adjuvant chemotherapy for cancer. PMID:10773998

Analysis of orthopedic surgery of bone metastases in breast cancer patients  

PubMed Central

Background Breast cancer is the most common malignancy and the second leading cause of death in women. Because bone metastases are a common finding in patients with breast cancer, they are of major clinical concern. Methods In 115 consecutive patients with bone metastases secondary to breast cancer, 132 surgical procedures were performed. Medical records and imaging procedures were reviewed for age, treatment of the primary tumor, clinical symptoms, surgical treatment, complications, and survival. Results The overall survival of patients with metastatic breast cancer was dependent on the site and the amount of the metastases. Age was not a prognostic factor for survival. If the result of the orthopaedic surgery was a wide resection (R0) survival was significantly better than in the R1 (marginal resection – tumor resection in sane tissue) or R2 (intralesional resection) situation. Concerning the orthopaedic procedures there was no survival difference. Conclusion In conclusion a wide (R0) resection and the absence of pathological fracture and visceral metastases were predictive for longer survival in univariate analysis. Age and the type of orthopaedic surgery had no impact on survival in multivariate analysis. The resection margins lost significance. The standard of care for patients with metastatic breast cancer to the bone requires a multidisciplinary approach. PMID:23181392

Tangential Radiotherapy Without Axillary Surgery in Early-Stage Breast Cancer: Results of a Prospective Trial  

SciTech Connect

Purpose: To determine the risk of regional-nodal recurrence in patients with early-stage, invasive breast cancer, with clinically negative axillary nodes, who were treated with breast-conserving surgery, 'high tangential' breast radiotherapy, and hormonal therapy, without axillary surgery or the use of a separate nodal radiation field. Methods and Materials: Between September 1998 and November 2003, 74 patients who were {>=}55 years of age with Stage I-II clinically node-negative, hormone-receptor-positive breast cancer underwent tumor excision to negative margins without axillary surgery as a part of a multi-institutional prospective study. Postoperatively, all underwent high-tangential, whole-breast radiotherapy with a boost to the tumor bed, followed by 5 years of hormonal therapy. Results: For the 74 patients enrolled, the median age was 74.5 years, and the median pathologic tumor size was 1.2 cm. Lymphatic vessel invasion was present in 5 patients (7%). At a median follow-up of 52 months, no regional-nodal failures or ipsilateral breast recurrences had been identified (95% confidence interval, 0-4%). Eight patients died, one of metastatic disease and seven of other causes. Conclusion: In this select group of mainly older patients with early-stage hormone-responsive breast cancer and clinically negative axillary nodes, treatment with high-tangential breast radiotherapy and hormonal therapy, without axillary surgery, yielded a low regional recurrence rate. Such patients might be spared more extensive axillary treatment (axillary surgery, including sentinel node biopsy, or a separate nodal radiation field), with its associated time, expense, and morbidity.

Prognostic factors affecting survival of patients with cancer-related pericardial effusion managed by surgery  

PubMed Central

Background Although pericardial effusion (PE) is not uncommon in patients with cancer, it may lead to cardiac tamponade, a life-threatening condition. Prompt life-saving treatment is essential, and also allows the continuation of the cancer treatment. The aim of this study was to determine the prognostic factors for survival in patients with cancer who were treated surgically for PE. Methods We retrospectively reviewed the medical records of 55 patients with cancer with PE between January 2003 and October 2012, who were treated with a pericardial window operation. Overall survival (OS) was estimated from the date of surgery, and patients were followed until the time of the final visit or time of death. Clinical outcomes and candidate prognostic factors were analyzed. Results The median age of patients was 57 years (range 29 to 82 years), and 31 patients (56.4%) were male. The most common primary malignancy was lung cancer (65.5%), followed by breast cancer (10.9%). Fifteen patients (27.3%) developed recurrence of PE after surgery. The median OS duration was 4 months (range 0 to 39 months). Multivariate analysis found that evidence of pericardial metastasis on preoperative imaging (P?=?0.029) and confirmation of malignant cells in the PE and/or pericardial tissue (P?=?0.034) were associated with reduced OS. Conclusion Evidence of pericardial metastasis on preoperative imaging and cytopathologic confirmation that the PE and/or pericardial tissue are positive for malignant cells can be used to predict poor clinical outcomes in patients with cancer-related PE.

A goggle navigation system for cancer resection surgery  

NASA Astrophysics Data System (ADS)

We describe a portable fluorescence goggle navigation system for cancer margin assessment during oncologic surgeries. The system consists of a computer, a head mount display (HMD) device, a near infrared (NIR) CCD camera, a miniature CMOS camera, and a 780 nm laser diode excitation light source. The fluorescence and the background images of the surgical scene are acquired by the CCD camera and the CMOS camera respectively, co-registered, and displayed on the HMD device in real-time. The spatial resolution and the co-registration deviation of the goggle navigation system are evaluated quantitatively. The technical feasibility of the proposed goggle system is tested in an ex vivo tumor model. Our experiments demonstrate the feasibility of using a goggle navigation system for intraoperative margin detection and surgical guidance.

Indications for and limits of conservative surgery in breast cancer.  

PubMed

Improvements in diagnostic techniques and, above all, breast cancer screening campaigns - essential for early diagnosis - have enabled the objectives of conservative surgery to be pursued: disease control, no or low incidence of recurrences and an excellent esthetic result. However, to reach these objectives, it is essential to ensure a careful evaluation of the medical history of every patient, a detailed clinical examination and the correct interpretation of imaging. Particular attention should be paid to all factors influencing the choice of treatment and/or possible local recurrence: age, site, tumor volume, genetic predisposition, pregnancy, previous radiotherapy, pathological features, and surgical margins. The decision to undertake conservative treatment thus requires a multidisciplinary approach involving pathologists, surgeons and oncological radiologists, as well, of course, as the patient herself.

Reconstructive surgery in young women with breast cancer.  

PubMed

Recovery of body image after mastectomy is essential for physical and mental quality of life. Partial or total mastectomy deformities can be reversed by reconstructive surgical procedures. Young women with breast cancer have specific characteristics related to the age of onset of the disease, prognosis and reconstructive expectations. Patient individualization is the key to a successful breast reconstruction. Autologous and prosthetic reconstruction are the two main techniques used for breast reconstruction. Each reconstructive technique has its own indications, advantages and limitations. Timing of the surgery is primarily determined by the requirement for adjuvant radiotherapy, so an immediate or a delayed approach can be recommended. In patients in whom the need for adjuvant radiotherapy is in doubt, a delayed-immediate approach is the best to optimize aesthetic and oncologic outcomes. Prophylactic mastectomy is also being indicated in a growing number of patients. In these patients it is important to choose a similar reconstructive procedure on both sides to achieve breast symmetry. PMID:20721689

Complex permittivities of breast tumor tissues obtained from cancer surgeries  

NASA Astrophysics Data System (ADS)

The variability in measurements of complex permittivities of tumor tissues between multiple samples could be attributed to the volume fraction of cancer cells in the excised tumor tissue. By the use of a digital photomicrograph image and hematoxylin-eosin staining, it was found that the malignant tumor tissue was not fully occupied by the cancer cells, but the cells were distributed locally in the stroma cells depending on the growth of cancer. The results showed that the volume fraction of cancer cells in the tumor tissue had a correlation to the measured conductivity and dielectric constant in the frequency range from 1 GHz to 6 GHz. It introduces a method to understand and gauge variability in measurements between different tumors.

Transoral robotic surgery in head and neck cancer.  

PubMed

Robots have invaded industry and, more recently, the field of medicine. Following the development of various prototypes, Intuitive Surgical® has developed the Da Vinci surgical robot. This robot, designed for abdominal surgery, has been widely used in urology since 2000. The many advantages of this transoral robotic surgery (TORS) are described in this article. Its disadvantages are essentially its high cost and the absence of tactile feedback. The first feasibility studies in head and neck cancer, conducted in animals, dummies and cadavers, were performed in 2005, followed by the first publications in patients in 2006. The first series including more than 20 patients treated by TORS demonstrated the feasibility for the following sites: oropharynx, supraglottic larynx and hypopharynx. However, these studies did not validate the oncological results of the TORS technique. TORS decreases the number of tracheotomies, and allows more rapid swallowing rehabilitation and a shorter length of hospital stay. Technical improvements are expected. Smaller, more ergonomic, new generation robots, therefore more adapted to the head and neck, will probably be available in the future. PMID:22154206

Robotic-Assisted Fertility-Sparing Surgery for Early Ovarian Cancer  

PubMed Central

Objective: To show the feasibility and safety of robotic-assisted laparoscopic fertility-sparing surgery for early-stage ovarian cancer in women of reproductive age. Methods and Design: The first patient was a 29-year-old para 0 woman with well-differentiated endometrioid adenocarcinoma of the ovary and complex endometrial hyperplasia with marked atypia. The second patient was a 31-year-old para 0 woman with an immature grade 1 teratoma. Both patients underwent robotic-assisted laparoscopic surgical staging. Results: In the first patient, there were no intra- or postoperative complications. Operative time was 5 hours 43 minutes and estimated blood loss was 100 mL. She was discharged home on postoperative day 1. She received 3 cycles of carboplatin and paclitaxel, as well as medroxyprogesterone acetate for the duration of chemotherapy. She conceived twice spontaneously since surgery and had two successful deliveries. She currently has no evidence of disease. In the second patient, there were no intra- or postoperative complications. Operative time was 2 hours 52 minutes and estimated blood loss was 200 mL. She was discharged home on postoperative day 1. She declined adjuvant chemotherapy with bleomycin, etoposide, and cisplatin. She conceived spontaneously 4 months later and had a normal vaginal delivery. She currently has no evidence of disease. Conclusions: Because fertility-sparing surgery is now accepted as a viable option in young women with early-stage ovarian cancer, less invasive techniques are being used. With the advent of robotic-assisted surgery and its advantages over conventional laparoscopy, we show that it is a safe and feasible approach in select patients. This is the first reported series on robotic fertility-sparing surgery, but more research is needed. PMID:24960498

Computer assisted intervention surgery planning and navigation for percutaneous microwave ablation of lung cancer  

NASA Astrophysics Data System (ADS)

Microwave ablation is a promising option in lung cancer therapy. However, it's rarely used in percutaneous lung cancer therapy compared to liver cancer, because the presence of a large amount of air within the lung creates significant back shadowing artifacts that preclude adequate delineation of anatomic details on sonography. To utilize microwave ablation in malignant lung tumor therapy, we developed a novel percutaneous intervention surgery navigation system (CAINS-I), which capitalizes on using computer assisted technology to help lung cancer patients whose condition are not amenable to surgical resection, sonographic guidance and intraoperative CT surgery. In these surgeries, preoperative CT images with patient respiration state are first acquired, which are then visualized using GPU-accelerated volume rendering. The optimal surgery trajectories are then planned based on 3D thermal field computation and surgery simulation in the surgery planning software. During the surgery, the patient breath is control by a portable volume ventilator system which could limit the movement and displacement of the tumor. Then the microwave probe is punctured into the tumor according to the dynamic respiratory state and the tumor is ablated by microwave energy. After the surgery, postoperative CT are acquired and compared to the preoperative CT, and the surgery is evaluated by compare preoperative and postoperative CT images. The development of this technique represented an advance from the traditional ways for lung cancer therapy and significantly extends the indications of microwave ablation.

Quality of life in rectal cancer patients after radical surgery: a survey of Chinese patients  

PubMed Central

Background We aimed to investigate the impact of sociodemographic and clinical characteristics on health-related quality of life (HRQoL) in disease-free survivors after radical surgery for rectal cancer in a Chinese mainland population. Methods We performed a cross-sectional survey from August 2002 to February 2011 by use of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-CR38 questionnaires of 438 patients who underwent curative surgery for rectal cancer. Patients who were followed up for a minimum of 6 months, had no relevant major comorbidities and whose disease had not recurred were asked to complete both questionnaires. The impact of sociodemographic and clinical characteristics on HRQoL were compared by univariate and multivariate regression analyses. Results In total, 285 patients responded to the survey (response rate, 65.1%). Psychological-related HRQoL variables such as emotional function (P?=?0.021) and future perspectives (P?=?0.044) were poorer for younger patients than for older patients; and physiological-related HRQoL was reflected by physical function (P?=?0.039), which was poorer for older patients than for younger patients. In terms of physiologic function and symptoms concerning HRQoL, such as pain (P?=?0.002) and insomnia (P?=?0.018), females had lower values than males. Low education and unemployment were associated with a worse HRQoL. HRQoL was worse for patients with stomas compared to those without, especially in psychosocial areas such as role function (P?=?0.025), social function (P <0.001) and body image (P?=?0.004). Financial HRQoL was worse for younger patients and patients with stoma. Conclusions HRQoL aspects and degrees to which they were impaired after curative surgery for rectal cancer were different when compared by many sociodemographic and clinical factors in Chinese mainland patients.

Is lack of surgery for older breast cancer patients in the UK explained by patient choice or poor health? A prospective cohort study  

PubMed Central

Background: Older women have lower breast cancer surgery rates than younger women. UK policy states that differences in cancer treatment by age can only be justified by patient choice or poor health. Methods: We investigate whether lack of surgery for older patients is explained by patient choice/poor health in a prospective cohort study of 800 women aged ?70 years diagnosed with operable (stage 1–3a) breast cancer at 22 English breast cancer units in 2010–2013. Data collection: interviews and case note review. Outcome measure: surgery for operable (stage 1–3a) breast cancer <90 days of diagnosis. Logistic regression adjusts for age, health measures, tumour characteristics, socio-demographics and patient's/surgeon's perceived responsibility for treatment decisions. Results: In the univariable analyses, increasing age predicts not undergoing surgery from the age of 75 years, compared with 70–74-year-olds. Adjusting for health measures and choice, only women aged ?85 years have reduced odds of surgery (OR 0.18, 95% CI: 0.07–0.44). Each point increase in Activities of Daily Living score (worsening functional status) reduced the odds of surgery by over a fifth (OR 0.23, 95% CI: 0.15–0.35). Patient's role in the treatment decisions made no difference to whether they received surgery or not; those who were active/collaborative were as likely to get surgery as those who were passive, that is, left the decision up to the surgeon. Conclusion: Lower surgery rates, among older women with breast cancer, are unlikely to be due to patients actively opting out of having this treatment. However, poorer health explains the difference in surgery between 75–84-year-olds and younger women. Lack of surgery for women aged ?85 years persists even when health and patient choice are adjusted for. PMID:24292450

Improving quality through process change: a scoping review of process improvement tools in cancer surgery  

PubMed Central

Background Surgery is a cornerstone of treatment for malignancy. However, significant variation has been reported in patterns and quality of cancer care for important health outcomes, including perioperative mortality. Surgical process improvement tools (SPITs) have been developed that focus on enhancing the processes of care at the point of care, as a means of quality improvement. This study describes SPITs and develops a conceptual framework by synthesizing the available literature on these novel quality improvement tools. Methods A scoping review was conducted based on instruments developed for quality improvement in surgery. The search was executed on electronically indexed sources (MEDLINE, EMBASE, and the Cochrane library) from January 1990 to March 2011. Data were extracted, tabulated and reported thematically using a narrative synthesis approach. These results were used to develop a conceptual framework that describes and classifies SPITs. Results 232 articles were reviewed for data extraction and analysis. SPITs identified were classified into 3 groups: clinical mapping tools, structure communication tools and error reduction instruments. The dominant instrument reported were clinical mapping tools, including: clinical pathways (113, 48%), fast track (46, 20%) and enhanced recovery after surgery protocols (36, 15%). Outcomes reported included: length of stay (174, 75%), readmission rates (116, 50%), morbidity (116, 50%), mortality (104, 45%), and economic (60, 26%). Many gaps in the literature were recognized. Conclusion We have developed a conceptual framework of SPITs and identified gaps in current knowledge. These results will guide the design and development of new quality instruments in surgery.

Laparoscopic vs. open approach for colorectal cancer: evolution over time of minimal invasive surgery  

PubMed Central

Background In the late '80s the successes of the laparoscopic surgery for gallbladder disease laid the foundations on the modern use of this surgical technique in a variety of diseases. In the last 20 years, laparoscopic colorectal surgery had become a popular treatment option for colorectal cancer patients. Discussion Many studies emphasized on the benefits stating the significant advantages of the laparoscopic approach compared with the open surgery of reduced blood loss, early return of intestinal motility, lower overall morbidity, and shorter duration of hospital stay, leading to a general agreement on laparoscopic surgery as an alternative to conventional open surgery for colon cancer. The reduced hospital stay may also decrease the cost of the laparoscopic surgery for colorectal cancer, despite th higher operative spending compared with open surgery. The average reduction in total direct costs is difficult to define due to the increasing cost over time, making challenging the comparisons between studies conducted during a time range of more than 10 years. However, despite the theoretical advantages of laparoscopic surgery, it is still not considered the standard treatment for colorectal cancer patients due to technical limitations or the characteristics of the patients that may affect short and long term outcomes. Conclusions The laparoscopic approach to colectomy is slowly gaining acceptance for the management of colorectal pathology. Laparoscopic surgery for colon cancer demonstrates better short-term outcome, oncologic safety, and equivalent long-term outcome of open surgery. For rectal cancer, laparoscopic technique can be more complex depending on the tumor location. The advantages of minimally invasive surgery may translate better care quality for oncological patients and lead to increased cost saving through the introduction of active enhanced recovery programs which are likely cost-effective from the perspective of the hospital health-care providers.

Gynecologic examination and cervical biopsies after (chemo) radiation for cervical cancer to identify patients eligible for salvage surgery  

SciTech Connect

Purpose: The aim of this study was to evaluate efficacy of gynecologic examination under general anesthesia with cervical biopsies after (chemo) radiation for cervical cancer to identify patients with residual disease who may benefit from salvage surgery. Methods and Materials: In a retrospective cohort study data of all cervical cancer patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IB1 to IVA treated with (chemo) radiation between 1994 and 2001 were analyzed. Patients underwent gynecologic examination under anesthesia 8 to 10 weeks after completion of treatment. Cervical biopsy samples were taken from patients judged to be operable. In case of residual cancer, salvage surgery was performed. Results: Between 1994 and 2001, 169 consecutive cervical cancer patients received primary (chemo) radiation, of whom 4 were lost to follow-up. Median age was 56 years (interquartile range [IQR], 44-71) and median follow-up was 3.5 years (IQR, 1.5-5.9). In each of 111 patients a biopsy sample was taken, of which 90 (81%) showed no residual tumor. Vital tumor cells were found in 21 of 111 patients (19%). Salvage surgery was performed in 13 of 21 (62%) patients; of these patients, 5 (38%) achieved long-term, complete remission after salvage surgery (median follow-up, 5.2 years; range, 3.9-8.8 years). All patients with residual disease who did not undergo operation (8/21) died of progressive disease. Locoregional control was more often obtained in patients who underwent operation (7 of 13) than in patients who were not selected for salvage surgery (0 of 8 patients) (p < 0.05). Conclusions: Gynecologic examination under anesthesia 8 to 10 weeks after (chemo) radiation with cervical biopsies allows identification of those cervical cancer patients who have residual local disease, of whom a small but significant proportion may be salvaged by surgery.

Mayo Clinic study finds less invasive surgery detects residual breast cancer in lymph nodes after chemotherapy  

Cancer.gov

Most patients whose breast cancer has spread to their lymph nodes have most of the lymph nodes in their armpit area removed after chemotherapy to see if any cancer remains. A study conducted through the American College of Surgeons Oncology Group and led by the Mayo Clinic shows that a less invasive procedure known as sentinel lymph node surgery successfully identified whether cancer remained in lymph nodes in 91 percent of patients with node-positive breast cancer who received chemotherapy before their surgery. In sentinel lymph node surgery, only a few lymph nodes, the ones most likely to contain cancer, are removed. The findings are being presented at the 2012 CTRC-AACR San Antonio Breast Cancer Symposium.

The Role of Immediate Recurrent Laryngeal Nerve Reconstruction for Thyroid Cancer Surgery  

PubMed Central

Unilateral vocal fold paralysis (UVFP) is one of the most serious problems in conducting surgery for thyroid cancer. Different treatments are available for the management of UVFP including intracordal injection, type I thyroplasty, arytenoid adduction, and laryngeal reinnervations. The effects of immediate recurrent laryngeal nerve (RLN) reconstruction during thyroid cancer surgery with or without UVFP before the surgery were evaluated with videostroboscopic, aerodynamic, and perceptual analyses. All subjects experienced postoperative improvements in voice quality. Particularly, aerodynamic analysis showed that the values for all patients entered normal ranges in both patients with and without UVFP before surgery. Immediate RLN reconstruction has the potential to restore a normal or near-normal voice by returning thyroarytenoid muscle tone and bulk seen with vocal fold denervation. Immediate RLN reconstruction is an efficient and effective approach to the management of RLN resection during surgery for thyroid cancer. PMID:20628531

The role of cytoreductive surgery in advanced ovarian cancer: the general surgeon's perspective.  

PubMed

Ovarian cancer is one of the most common and lethal cancers worldwide and is usually diagnosed at advanced stages. A radical and effective management of advanced ovarian cancer is needed. Cytoreductive surgery followed by intravenous chemotherapy is currently the gold standard for the management of this disease. However, the recurrence rates still remain high. The introduction of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) combined with complete cytoreductive surgery is a well-promising approach for advanced-stage disease, as well as for recurrent cases. This review aimed to present the surgical management of advanced ovarian cancer and the recent literature about the role and the therapeutic effectiveness of cytoreduction. PMID:25261641

Risk of Metachronous Colon Cancer Following Surgery for Rectal Cancer in Mismatch Repair Gene Mutation Carriers  

PubMed Central

Background Despite regular surveillance colonoscopy, the metachronous colorectal cancer risk for mismatch repair (MMR) gene mutation carriers after segmental resection for colon cancer is high and total or subtotal colectomy is the preferred option. However, if the index cancer is in the rectum, management decisions are complicated by considerations of impaired bowel function. We aimed to estimate the risk of metachronous colon cancer for MMR gene mutation carriers who underwent a proctectomy for index rectal cancer. Methods This retrospective cohort study comprised 79 carriers of germline mutation in a MMR gene (18 MLH1, 55 MSH2, 4 MSH6, and 2 PMS2) from the Colon Cancer Family Registry who had had a proctectomy for index rectal cancer. Cumulative risks of metachronous colon cancer were calculated using the Kaplan–Meier method. Results During median 9 years (range 1–32 years) of observation since the first diagnosis of rectal cancer, 21 carriers (27 %) were diagnosed with metachronous colon cancer (incidence 24.25, 95 % confidence interval [CI] 15.81–37.19 per 1,000 person-years). Cumulative risk of metachronous colon cancer was 19 % (95 % CI 9–31 %) at 10 years, 47 (95 % CI 31–68 %) at 20 years, and 69 % (95 % CI 45–89 %) at 30 years after surgical resection. The frequency of surveillance colonoscopy was 1 colonoscopy per 1.16 years (95 % CI 1.01–1.31 years). The AJCC stages of the metachronous cancers, where available, were 72 % stage I, 22 % stage II, and 6 % stage III. Conclusions Given the high metachronous colon cancer risk for MMR gene mutation carriers diagnosed with an index rectal cancer, proctocolectomy may need to be considered. PMID:23358792

Patterns of Locoregional Recurrence After Surgery and Radiotherapy or Chemoradiation for Rectal Cancer  

SciTech Connect

Purpose: To identify patterns of locoregional recurrence in patients treated with surgery and preoperative or postoperative radiotherapy or chemoradiation for rectal cancer. Methods and Materials: Between November 1989 and October 2001, 554 patients with rectal cancer were treated with surgery and preoperative (85%) or postoperative (15%) radiotherapy, with 95% receiving concurrent chemotherapy. Among these patients, 46 had locoregional recurrence as the first site of failure. Computed tomography images showing the site of recurrence and radiotherapy simulation films were available for 36 of the 46 patients. Computed tomography images were used to identify the sites of recurrence and correlate the sites to radiotherapy fields in these 36 patients. Results: The estimated 5-year locoregional control rate was 91%. The 36 patients in the study had locoregional recurrences at 43 sites. There were 28 (65%) in-field, 7 (16%) marginal, and 8 (19%) out-of-field recurrences. Among the in-field recurrences, 15 (56%) occurred in the low pelvis, 6 (22%) in the presacral region, 4 (15%) in the mid-pelvis, and 2 (7%) in the high pelvis. Clinical T stage, pathologic T stage, and pathologic N stage were significantly associated with the risk of in-field locoregional recurrence. The median survival after locoregional recurrence was 24.6 months. Conclusions: Patients treated with surgery and radiotherapy or chemoradiation for rectal cancer had a low risk of locoregional recurrence, with the majority of recurrences occurring within the radiation field. Because 78% of in-field recurrences occur in the low pelvic and presacral regions, consideration should be given to including the low pelvic and presacral regions in the radiotherapy boost field, especially in patients at high risk of recurrence.

The perioperative management of patients with gynaecological cancer undergoing major surgery: A debated clinical challenge.  

PubMed

Major extensive surgery still represents a cornstone of therapy of gynaecological cancer, and the adoption of implemented clinical guidelines for perioperative management can significantly decrease patient morbidity and mortality and reduce hospital stay. The overall risk of deep venous thrombosis in patients undergoing gynaecological surgery ranges from 7% to 45%, and fatal pulmonary embolism occurs in approximately 1% of these women. A meta-analyses of randomised trials showed a significant decrease in deep venous thrombosis in women receiving unfractioned heparin [UFH] compared with controls, and revealed no significant difference in deep venous thrombosis and pulmonary embolism between patients who received UFH and those who received low-molecular weight heparin [LMWH]. Potential advantages favouring LMWH over UFH include once-daily versus repeated daily injections and a lower risk of heparin-induced thrombocytopenia. All patients undergoing major surgical operations should receive LMWH that should be started preoperatively and then given for 7-10 days at least and prolonged for up to 4 weeks in high-risk cases. Antithrombotic mechanical methods can be added to pharmacological agents, but should not been used alone. Cephalosporins and amoxicillin-clavulanic acid have been widely used in gynaecological surgery prophylaxis. Both amoxicillin-clavulanic acid and cefazolin have good in vitro activity against the microbes more frequently involved in postoperative infections, such as Gram-negative bacilli, but amoxicillin-clavulanic acid is more effective against anaerobes. A single dose of antibiotics has been shown to be as effective as multiple doses in many trials that have compared a single-dose regimen with a multiple-dose regimen. Amoxicillin-clavulanic acid prophylaxis at the induction of anaesthesia can be suggested for gynaecological cancer patients undergoing major gynaecological surgery with or without colorectal resection. An additional antibiotic dose is recommended for prolonged operations or when intraoperative blood loss is important. Cephalosporins can be administered to women with a history of penicillin allergy not manifested by an immediate hypersensitivity reaction, whereas tigecyclin should be reserved to patients with a prior anaphylactic reaction to beta-lactams. Recent meta-analyses of randomised trials on patients undergoing elective colorectal surgery found more anastomotic leakages in patients who had preoperative mechanical bowel preparation with oral administration of different solutions than in those who had not, whereas there were no significant differences between the two arms as for wound infections, other septic complications, and non-septic complications. Therefore, preoperative mechanical bowel cleansing is not warranted for gynaecological cancer patients scheduled for surgery that may involve colon-rectum. After major abdominal gynaecological surgery, early oral feeding (within the first 24h regardless of the resolution of postoperative ileus) appears to be associated with increased nausea, shorter time to the presence of bowel sound, shorter time to first solid diet, and a trend toward shorter hospital stay when compared with delayed feeding. Since early oral feeding is safe but associated with increased nausea, the decision whether to adopt this postoperative regimen should be individualised. Decision making processes about thromboprophylaxis, antibiotic prophylaxis, bowel preparation for surgery that may involve colon-rectum, and timing of postoperative oral feeding will become more and more relevant for improved safety and quality of life of women with gynaecological cancer.

[Condition of patients who require heart surgery during treatment for advanced digestive cancer and early recurrence after surgery- an assessment from the viewpoint of digestive surgeons].  

PubMed

The need for cardiac surgery among patients undergoing treatment for advanced digestive cancer is limited to the following situations:(i) heart diseases that can be life threatening if left untreated and that cannot be cured by medicinal treatment alone (e.g., cardiac tumors) and (ii) heart diseases (e.g., infectious endocarditis and pulmonary thromboembolism) occurring after digestive cancer surgery that need emergency treatment and that are resistant to medicinal treatment. We encountered 2 cases that required cardiac surgery.( Case 1) A 68-year-old woman with advanced gastric carcinoma accompanied by pyloric stenosis and left atrial myxoma underwent radical surgery for gastric cancer( Stage IIIA). Subsequently, the left atrial myxoma was resected before adjuvant chemotherapy for the treatment of gastric cancer was administered. One month after the surgery, multiple liver metastases appeared. However, they disappeared after chemotherapy was completed, and the patient survived for more than 3 years with complete response. (Case 2) A 67-year-old woman who underwent a Hartmann operation for obstructive rectal cancer (Stage II) experienced infectious endocarditis after the surgery. Because the endocarditis was resistant to medicinal treatment and acute heart failure was anticipated, cardiac surgery was performed. Approximately 2 months after the surgery, the bacilli( methicillin-resistant Staphylococcus aureus [MRSA]) were not found in blood culture. However, multiple liver metastases appeared immediately after the disappearance of the bacilli, and the patient died 3 months after the surgery. In both cases, cancer recurrence occurred early after cardiac surgery. Excessive surgical stress due to cardiac surgery may have promoted cancer recurrence. A decision pertaining to the timing of cardiac surgery is difficult in cases of patients with advanced digestive cancer and co-existing heart disease, which cannot be cured by medicinal treatment.

Conservative surgery without radiotherapy in the treatment of patients with early-stage invasive breast cancer. A review.  

PubMed Central

OBJECTIVE: The authors determined whether some patients with clinical stage I or II invasive breast cancer can be adequately treated by conservative surgery without radiotherapy. SUMMARY BACKGROUND DATA: Currently, there are many patients who are being treated in this manner in both academic and community hospitals. This approach is not as effective as either mastectomy or conservative surgery followed by radiotherapy in preventing local recurrence. However, there may be subsets of patients who might be adequately treated by surgery alone with acceptably low recurrence rates. METHODS: The authors reviewed retrospective studies of conservative surgery alone and of randomized trials comparing the results of treatment with and without postoperative radiotherapy. RESULTS: The local recurrence rate is unacceptably high when random patients are treated with conservative surgery without radiotherapy. More favorable results may be possible when relatively wide excisions are performed on selected postmenopausal patients with small lesions without an extensive intraductal component, lymphatic or blood-vessel invasion, and histologically negative axillary nodes. The role of tamoxifen in reducing the risk of breast recurrence is uncertain. Despite salvage therapy, some individuals may develop disseminated disease as a result of local recurrence. CONCLUSIONS: The authors believe that conducting carefully designed prospective studies of conservative surgery alone is reasonable for patients who are adequately informed of the potential risks of omitting radiation therapy. However, currently, patients should not be treated with conservative surgery alone (without radiotherapy) without such stringent guidelines. PMID:7618975

Optimal Time of Initiating Adjuvant Chemotherapy After Curative Surgery in Colorectal Cancer Patients  

PubMed Central

Purpose Adjuvant chemotherapy is routinely recommended for locally advanced colorectal cancer (CRC). There are very few data for the optimal starting date of adjuvant chemotherapy after the surgery. This study aimed to evaluate the effectiveness of earlier adoption of adjuvant chemotherapy after curative surgery for stage III CRC. Methods In this study, 159 patients with stage III CRC, who had undergone a curative resection, were enrolled retrospectively. Patients were categorized into 3 groups representing different timings to initiate the chemotherapy; less than 2 weeks (group 1), 3 to 4 weeks (group 2), and more than 5 weeks (group 3). The overall survival rate (OS) and the relapse-free survival rate (RFS) were analyzed to evaluate the effectiveness of adjuvant chemotherapy. Results The 5-year OSs of the patients were 73.7% in group 1, 67.0% in group 2, and 55.2% in group 3. The 5-year RFSs of the patients were 48.8% in group 1, 64.7% in group 2, and 57.1% in group 3. There were no significant differences in either the OS or the RFS (P = 0.200, P = 0.405). Conclusion Starting chemotherapy earlier than 6 weeks after surgery does not show any significant difference. Thus, although adjuvant chemotherapy should preferably begin within 6 weeks, the starting date should not necessarily be hastened, and the patient's general condition should be taken into consideration.

The choice of anaesthetic--sevoflurane or propofol--and outcome from cancer surgery: A retrospective analysis  

PubMed Central

Background Commonly used inhalational hypnotics, such as sevoflurane, are pro-inflammatory, whereas the intravenously administered hypnotic agent propofol is anti-inflammatory and anti-oxidative. A few clinical studies have indicated similar effects in patients. We examined the possible association between patient survival after radical cancer surgery and the use of sevoflurane or propofol anaesthesia. Patients and methods Demographic, anaesthetic, and surgical data from 2,838 patients registered for surgery for breast, colon, or rectal cancers were included in a database. This was record-linked to regional clinical quality registers. Cumulative 1- and 5-year overall survival rates were assessed using the Kaplan–Meier method, and estimates were compared between patients given propofol (n = 903) or sevoflurane (n = 1,935). In a second step, Cox proportional hazard models were calculated to assess the risk of death adjusted for potential effect modifiers and confounders. Results Differences in overall 1- and 5-year survival rates for all three sites combined were 4.7% (p = 0.004) and 5.6% (p < 0.001), respectively, in favour of propofol. The 1-year survival for patients operated for colon cancer was almost 10% higher after propofol anaesthesia. However, after adjustment for several confounders, the observed differences were not statistically significant. Conclusion Propofol anaesthesia might be better in surgery for some cancer types, but the retrospective design of this study, with uneven distributions of several confounders, distorted the picture. These uncertainties emphasize the need for a randomized controlled trial. PMID:24857018

Cervical bronchogenic cysts mimic metastatic lymph nodes during thyroid cancer surgery  

PubMed Central

Purpose Although congenital bronchogenic cysts in the cervical region, especially in the thyroid or perithyroidal area, are rare, distinguishing them from other cervical cystic lesions (e.g., thyroglossal duct and branchial cleft cysts) and metastatic cervical lymph nodes is difficult preoperatively. Additionally, cystic degeneration of metastatic lymph nodes is common in patients with thyroid cancer. We investigated the clinical characteristics and proper treatment for individuals with cervical bronchogenic cysts. Methods Of the 18,900 patients treated for thyroid cancer, 18 patients with pathologically confirmed bronchogenic cysts were retrospectively reviewed. Bilateral total thyroidectomy or less than total thyroidectomy with central compartment node dissection, including cystic mass excision was done and cystic mass was confirmed by postoperative pathologic examination. Results All cervical bronchogenic cysts were asymptomatic. Their mean size was 1.2 cm (range, 0.3 to 3 cm). Of these 18 patients, 15 did not have any abnormal radiological findings, except for lymphadenopathy during preoperative evaluations. Most bronchogenic cysts were detected around the thyroid and paratracheal areas. On preoperative imaging and intraoperatively, most were indistinguishable from metastatic cervical lymph nodes or other cystic lesions. Conclusion Although cervical bronchogenic cysts are rare and benign, they should be distinguished from other cystic cervical masses, especially metastatic cervical lymph nodes associated with thyroid cancer. Possible cervical bronchogenic cysts found during thyroid cancer evaluation or surgery should be surgically excised. PMID:24851222

Laparoscopic-Assisted Staging Surgery for Korean Women With Endometrial Cancer  

PubMed Central

Background and Objective: In recent years, the incidence of endometrial cancer has gradually increased in Korea, and the use of laparoscopically assisted staging surgery (LASS) is increasing in this field. We conducted this study to evaluate the feasibility of LASS in Korean women with endometrial cancer. Methods: We conducted a retrospective review of 35 Korean women with endometrial cancer who were managed laparoscopically. Results: The median age and BMI were 57 years (range, 28 to 81) and 25.8 kg/m2 (range, 20.9 to 37.2), respectively. The median operating time, estimated blood loss, and length of hospital stay were, respectively, 150 minutes (range, 95 to 410), 250 mL (range, 50 to 1000), and 8 days (range, 3 to 20). No conversion to laparotomy was noted. The median number of harvested lymph nodes was 22 (range, 10 to 41) in pelvic lymph nodes and 7 (range, 2 to 21) in paraaortic lymph nodes. No vault recurrence or port-site metastasis was noted until the last follow-up. Conclusions: LASS can be performed without additional morbidity and complications, and might be feasible in Korean women with endometrial cancer. PMID:18435887

The nutritional risk is a independent factor for postoperative morbidity in surgery for colorectal cancer  

PubMed Central

Purpose The authors evaluate the prevalence of malnutrition and its effect on the postoperative morbidity of patients after surgery for colorectal cancer. Methods Three hundred fifty-two patients were enrolled prospectively. Nutritional risk screening 2002 (NRS 2002) score was calculated through interview with patient on admission. Clinical characteristics, tumor status and surgical procedure were recorded. Results The prevalence of patients at nutritional risk was 28.1 per cent according to the NRS 2002. The rate of postoperative complication was 27%. There was a significant difference in postoperative complication rates between patients at nutritional risk and those not at risk (37.4% vs. 22.9%, P = 0.006). Nutritional risk was identified as an independent predictor of postoperative complications (odds ratio, 3.05; P = 0.045). Nutritional risk increased the rate of anastomotic leakage (P = 0.027) and wound infection (P = 0.01). Conclusion NRS may be a prognostic factor for postoperative complication after surgery for colorectal cancer. A large scaled prospective study is needed to confirm whether supplementing nutritional deficits reduces postoperative complication rates. PMID:24783180

Effect of Gum Chewing on the Recovery From Laparoscopic Colorectal Cancer Surgery  

PubMed Central

Purpose We aimed to examine the effect of gum chewing after laparoscopic colorectal cancer surgery. Methods We reviewed the medical records of patients who underwent laparoscopic colorectal cancer surgery in Incheon St. Mary's Hospital, The Catholic University of Korea School of Medicine. We divided the patients into 2 groups: group A consisted of 67 patients who did not chew gum; group B consisted of 65 patients who chewed gum. We analyzed the short-term clinical outcomes between the two groups to evaluate the effect of gum chewing. Results The first passage of gas was slightly earlier in group B, but the difference was not significant. However, the length of hospital stay was 6.7 days in group B, which was significantly shorter than that in group A (7.3 days, P = 0.018). Conclusion This study showed that length of postoperative hospital stay was shorter in the gum-chewing group. In future studies, we expect to elucidate the effect of gum chewing on the postoperative recovery more clearly. PMID:24466540

Intravenous paracetamol infusion: Superior pain management and earlier discharge from hospital in patients undergoing palliative head-neck cancer surgery  

PubMed Central

Background: Paracetamol; a cyclooxygenase inhibitor; acts through the central nervous system as well as serotoninergic system as a nonopioid analgesic. A prospective, double-blinded, and randomized-controlled study was carried out to compare the efficacy of preoperative 1g intravenous (iv) paracetamol with placebo in providing postoperative analgesia in head-neck cancer surgery. Materials and Methods: From 2008 February to 2009 December, 80 patients for palliative head-neck cancer surgery were randomly divided into (F) and (P) Group receiving ivplacebo and iv paracetamol, respectively, 5 min before induction. Everybody received fentanyl before induction and IM diclofenac for pain relief at8 hourly for 24 h after surgery. Visual analogue scale (VAS) and amount of fentanyl were measured for postoperative pain assessment (24 h). Results and Statistical analysis: The mean VAS score in 1st, 2nd postoperative hour, and fentanyl requirement was less and the need for rescue analgesic was delayed in ivparacetamol group which were all statistically significant. Paracetamol group had a shorter surgical intensive care unit (SICU) and hospital stay which was also statistically significant. Conclusion: The study demonstrates the effectiveness of ivparacetamol as preemptive analgesic in the postoperative pain control after head-neck cancer surgery and earlier discharge from hospital.

Does D3 surgery offer a better survival outcome compared to D1 surgery for gastric cancer? A result based on a hospital population of two decades as taking D2 surgery for reference  

PubMed Central

Background We conducted a retrospective study in our hospital in which we compared D1 with D3 through D2 lymphadenectomy for gastric cancer in terms of morbidity, postoperative mortality, long-term survival after surgery. Methods 567 patients who were performed curative intent between 1980 and 2003 were enrolled. 187 in the D1 group, 189 in the D2 group and 191 in the D3 group. Every procedure was verified by pathological analyses. The primary endpoints were 5-year overall survival. Results Median follow-up periods were 36 months and 60 months for D1 group and D3 group. Overall 5-year survival rate was significantly higher in patients underwent D3 surgery than in those performed D1 surgery (37.4% vs 48.7%; log-rank, p = 0.027). For the cases followed up to 120 months, the 10-year overall survival rate was 29% (95% CI, 22.1% to 35.9%) for the D1 group and 33.7% (95% CI, 26.6% to 40.8%) for the D3 group (log-rank, p = 0.005). Conclusions D1 surgery should be operated only for patients with Borrmann I disease. As D3 gastrectomy is associated with low mortality and adequate survival times when performed in selected institutions that have had sufficient experience with the operation and with postoperative management, we recommend D3 lymphadenectomy for patients with curable gastric cancer.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in peritoneal carcinomatosis from ovarian cancer  

PubMed Central

Background In selected patients with peritoneal carcinomatosis from ovarian cancer prognosis can be improved by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Methods Between September 1995 and February 1999, 19 patients (mean age 52 years, range 30–72 years) with peritoneal carcinomatosis from primary or recurrent epithelial ovarian carcinoma were operated with the aim of complete macroscopical cytoreduction. Surgery was followed by intraoperative HIPEC. The data was analyzed retrospectively. Results Eleven patients had recurrent and 8 primary ovarian cancer. The median progression free interval was 18 months (range 6–36 months). Macroscopically complete cytoreduction was achieved in 9 patients. Cisplatin (n = 16) or mitoxantrone (n = 3) were used for the intraoperative chemotherapy. The median intraabdominal inflow temperature was 41.5°C. Complications occurred in seven patients. Most frequent complications were anastomotic leakage (2/19) and intraabdominal abscess formation (2/19). One patient died postoperatively. The mean (± SD) overall survival time was 33(± 6) months with a 5-year survival rate of 15%. The survival was found to be influenced by the completeness of cytoreduction (44 ± 11 vs. 25 ± 6 months, p = 0.40), tumor volume (54 ± 10 versus 16 ± 4, p = 0.002) and presence of lymph node (38 ± 8 vs. 20 ± 8 months, p= 0.2) or liver metastases (51 ± 9 vs. 21 ± 6 months, p = 0.06). Conclusions Cytoreductive surgery combined with HIPEC is feasible and is associated with a reasonable morbidity and mortality. Complete cytoreduction may improve survival in select group of patients with low tumor volume and no organ metastases. PMID:15222884

Effects of chronic widespread pain on the health status and quality of life of women after breast cancer surgery  

PubMed Central

Background Most research and treatment of post-breast cancer chronic pain has focused on local or regional pain problems in the operated area. The purpose of this pilot study was to compare and contrast the pain characteristics, symptom impact, health status, and quality of life of post-breast cancer surgery women with regional chronic pain versus those with widespread chronic pain. Methods A cross-sectional, descriptive design compared two groups of women with chronic pain that began after surgery: regional pain (n = 11) and widespread pain (n = 12). Demographics, characteristics of the surgery, as well as standardized questionnaires that measured pain (Brief Pain Inventory (BPI), Short Form McGill Pain Questionnaire (MPQ-SF)), disease impact (Fibromyalgia Impact Questionnaire (FIQ), Functional Assessment of Cancer Therapy-Breast (FACT-B)), health status (Medical Outcomes Short Form (SF-36)) and quality of life (Quality of Life Scale (QOLS)) were gathered. Results There were no significant differences between the groups on any demographic or type of surgery variable. A majority of both groups described their pain as aching, tender, and sharp on the MPQ-SF. On the BPI, intensity of pain and pain interference were significantly higher in the widespread pain group. Differences between the two groups reached statistical significance on the FIQ total score as well as the FACT-B physical well-being, emotional well-being and breast concerns subscales. The SF-36 physical function, physical role, and body pain subscales were significantly lower in the widespread pain group. QOLS scores were lower in the widespread pain group, but did not reach statistical significance. Conclusion This preliminary work suggests that the women in this study who experienced widespread pain after breast cancer surgery had significantly more severity of pain, pain impact and lower physical health status than those with regional pain.

Risk of Cerebrovascular Events in Elderly Patients After Radiation Therapy Versus Surgery for Early-Stage Glottic Cancer  

SciTech Connect

Purpose: Comprehensive neck radiation therapy (RT) has been shown to increase cerebrovascular disease (CVD) risk in advanced-stage head-and-neck cancer. We assessed whether more limited neck RT used for early-stage (T1-T2 N0) glottic cancer is associated with increased CVD risk, using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database. Methods and Materials: We identified patients ?66 years of age with early-stage glottic laryngeal cancer from SEER diagnosed from 1992 to 2007. Patients treated with combined surgery and RT were excluded. Medicare CPT codes for carotid interventions, Medicare ICD-9 codes for cerebrovascular events, and SEER data for stroke as the cause of death were collected. Similarly, Medicare CPT and ICD-9 codes for peripheral vascular disease (PVD) were assessed to serve as an internal control between treatment groups. Results: A total of 1413 assessable patients (RT, n=1055; surgery, n=358) were analyzed. The actuarial 10-year risk of CVD was 56.5% (95% confidence interval 51.5%-61.5%) for the RT cohort versus 48.7% (41.1%-56.3%) in the surgery cohort (P=.27). The actuarial 10-year risk of PVD did not differ between the RT (52.7% [48.1%-57.3%]) and surgery cohorts (52.6% [45.2%-60.0%]) (P=.89). Univariate analysis showed an increased association of CVD with more recent diagnosis (P=.001) and increasing age (P=.001). On multivariate Cox analysis, increasing age (P<.001) and recent diagnosis (P=.002) remained significantly associated with a higher CVD risk, whereas the association of RT and CVD remained not statistically significant (HR=1.11 [0.91-1.37,] P=.31). Conclusions: Elderly patients with early-stage laryngeal cancer have a high burden of cerebrovascular events after surgical management or RT. RT and surgery are associated with comparable risk for subsequent CVD development after treatment in elderly patients.

Alternatives to surgery for early stage non-small cell lung cancer-ready for prime time?  

PubMed

Surgery is the standard of care for early stage non-small cell lung cancer (NSCLC), with lobectomy being the most oncologically sound resection. Medically inoperable patients and high-risk surgical candidates require effective alternatives to surgery; even operable patients may opt for less invasive options if they are proven to achieve similar outcomes to surgery. Minimally invasive local treatment modalities including dose-intensified conformal radiation therapy, most notably stereotactic ablative radiotherapy (SABR; also known as stereotactic body radiation therapy), and thermal ablation methods such as radiofrequency ablation (RFA) and microwave ablation (MWA) are emerging as promising treatment options whose roles in the treatment of early stage lung cancer are being defined. Early clinical experience and a rapidly growing body of prospective clinical trials, primarily in medically inoperable patients, are demonstrating encouraging effectiveness and safety outcomes in some cases approaching historical results with surgery. Given the very poor prognosis of the medically inoperable patient population, these alternatives to surgery, particularly SABR, are starting to be considered appropriate first-line therapy in properly selected patients, and prospective cooperative group trials to evaluate and optimize RFA and SABR in specific patient subsets are being conducted. For operable patients, prospective multi-center and cooperative groups trials of SABR are ongoing or completed, and international randomized trials of SABR vs. surgery have been initiated. Thus, promising alternatives to surgery for early stage NSCLC are ready for prime time evaluation in the setting of clinical trials, and participation in ongoing trials for both operable and medically inoperable patients is strongly encouraged.

Preferences for treatment of lobectomy in Chinese lung cancer patients: video-assisted thoracoscopic surgery or open thoracotomy?  

PubMed Central

Background This study was designed to investigate the preferences for treatment of lobectomy in Chinese lung cancer patients and differences in the psychological and social factors that influence treatment decision-making. Methods One hundred and forty patients with stage I lung cancer were recruited from Hebei Cangzhou Central Hospital. Before surgery, the patients completed a questionnaire that surveyed their preferences for treatment and the relevant influencing factors. Differences in psychological and social characteristics were compared between lung cancer patients who chose video-assisted thoracoscopic surgery (VATS) and those who opted for open thoracotomy. Results Among the 135 valid questionnaires, 79 patients preferred VATS and 56 patients chose open thoracotomy. Potential side effects, doctors’ recommendation, the prognosticated chance for cure, cosmesis, and financial burden influenced the patients’ decisions. Conclusion The minimally invasive advantages of VATS, including lesser trauma to the chest wall, earlier remission of postoperative pain, faster recovery, less bleeding, and improved cardiopulmonary function made VATS more attractive to patients needing lobectomy for lung cancer. However, the choice of VATS over open thoracotomy is still influenced by the degree of prognosticated cure and the feasibility of surgery. PMID:25336927

Factors influencing postoperative length of hospital stay after breast cancer surgery.  

PubMed

As part of a feasibility study to restructure the breast cancer services in Glasgow, factors influencing 'postoperative length of stay' (LOS) and bed utilisation in patients undergoing surgery for breast cancer were examined. Data for patients admitted at five hospitals between March 2007 and February 2008 was collected prospectively. Age, socio-demographic and clinico-pathologic factors were recorded. Independent affects of variables predicting prolonged LOS were assessed using binary logistic regression analysis. Of the 519 women, 252(49%) had screen-detected cancers with a median LOS of 1 day while 267(51%) had symptomatic cancers with a median LOS of 4 days (p < 0.001). On multivariate analysis, axillary procedure performed independently influenced prolonged LOS in both screen-detected and symptomatic cancers. In symptomatic cancers, comorbidities and deprivation also had some influence. While mastectomy with or without axillary surgery utilised 51% of the bed days, a further 20% were utilised by patients having re-operations. This study has helped in the planning of ambulatory surgery services and inpatient bed requirements for patients undergoing breast cancer surgery in Glasgow. PMID:22841480

A randomized trial of exercise on well-being and function following breast cancer surgery: the RESTORE trial  

PubMed Central

Objectives This study aimed to determine the effect of a moderate, tailored exercise program on health-related quality of life, physical function, and arm volume in women receiving treatment for nonmetastatic breast cancer. Methods Women who were within 4–12 weeks of surgery for stage I–III breast cancer were randomized to center-based exercise and lymphedema education intervention or patient education. Functional Assessment of Cancer Therapy–Breast Cancer (FACT-B), 6-min walk, and arm volume were performed at 3-month intervals through 18 months. Repeated measures analysis of covariance was used to model the total meters walked over time, FACT-B scores, and arm volume. Models were adjusted for baseline measurement, baseline affected arm volume, number of nodes removed, age, self-reported symptoms, baseline SF-12 mental and physical component scores, visit, and treatment group. Results Of the recruited 104 women, 82 completed all 18 months. Mean age (range) was 53.6 (32–82) years; 88% were Caucasian; 45% were employed full time; 44% were overweight; and 28% obese. Approximately, 46% had breast-conserving surgery; 79% had axillary node dissection; 59% received chemotherapy; and 64% received radiation. The intervention resulted in an average increase of 34.3 ml (SD=12.8) versus patient education (p=0.01). Changes in FACT-B scores and arm volumes were not significantly different. Conclusions With this early exercise intervention after breast cancer diagnosis, a significant improvement was achieved in physical function, with no decline in health-related quality of life or detrimental effect on arm volume. Implications for cancer survivors Starting a supervised exercise regimen that is tailored to an individual’s strength and stamina within 3 months following breast cancer surgery appears safe and may hasten improvements in physical functioning.

Pancreatic cancer circulating tumour cells express a cell motility gene signature that predicts survival after surgery  

PubMed Central

Background Most cancer deaths are caused by metastases, resulting from circulating tumor cells (CTC) that detach from the primary cancer and survive in distant organs. The aim of the present study was to develop a CTC gene signature and to assess its prognostic relevance after surgery for pancreatic ductal adenocarcinoma (PDAC). Methods Negative depletion fluorescence activated cell sorting (FACS) was developed and validated with spiking experiments using cancer cell lines in whole human blood samples. This FACS-based method was used to enrich for CTC from the blood of 10 patients who underwent surgery for PDAC. Total RNA was isolated from 4 subgroup samples, i.e. CTC, haematological cells (G), original tumour (T), and non-tumoural pancreatic control tissue (P). After RNA quality control, samples of 6 patients were eligible for further analysis. Whole genome microarray analysis was performed after double linear amplification of RNA. ‘Ingenuity Pathway Analysis’ software and AmiGO were used for functional data analyses. A CTC gene signature was developed and validated with the nCounter system on expression data of 78 primary PDAC using Cox regression analysis for disease-free (DFS) and overall survival (OS). Results Using stringent statistical analysis, we retained 8,152 genes to compare expression profiles of CTC vs. other subgroups, and found 1,059 genes to be differentially expressed. The pathway with the highest expression ratio in CTC was p38 mitogen-activated protein kinase (p38 MAPK) signaling, known to be involved in cancer cell migration. In the p38 MAPK pathway, TGF-?1, cPLA2, and MAX were significantly upregulated. In addition, 9 other genes associated with both p38 MAPK signaling and cell motility were overexpressed in CTC. High co-expression of TGF-?1 and our cell motility panel (? 4 out of 9 genes for DFS and ? 6 out of 9 genes for OS) in primary PDAC was identified as an independent predictor of DFS (p=0.041, HR (95% CI) = 1.885 (1.025 – 3.559)) and OS (p=0.047, HR (95% CI) = 1.366 (1.004 – 1.861)). Conclusions Pancreatic CTC isolated from blood samples using FACS-based negative depletion, express a cell motility gene signature. Expression of this newly defined cell motility gene signature in the primary tumour can predict survival of patients undergoing surgical resection for pancreatic cancer.

Neoadjuvant Treatment Does Not Influence Perioperative Outcome in Rectal Cancer Surgery  

SciTech Connect

Purpose: To identify the risk factors for perioperative morbidity in patients undergoing resection of primary rectal cancer, with a specific focus on the effect of neoadjuvant therapy. Methods and Materials: This exploratory analysis of prospectively collected data included all patients who underwent anterior resection/low anterior resection or abdominoperineal resection for primary rectal cancer between October 2001 and October 2006. The study endpoints were perioperative surgical and medical morbidity. Univariate and multivariate analyses of potential risk factors were performed. Results: A total of 485 patients were included in this study; 425 patients (88%) underwent a sphincter-saving anterior resection/low anterior resection, 47 (10%) abdominoperineal resection, and 13 (2%) multivisceral resection. Neoadjuvant chemoradiotherapy was performed in 100 patients (21%), and 168 (35%) underwent neoadjuvant short-term radiotherapy (5 x 5 Gy). Patient age and operative time were independently associated with perioperative morbidity, and operative time, body mass index >27 kg/m{sup 2} (overweight), and resection type were associated with surgical morbidity. Age and a history of smoking were confirmed as independent prognostic risk factors for medical complications. Neoadjuvant therapy was not associated with a worse outcome. Conclusion: The results of this prospective study have identified several risk factors associated with an adverse perioperative outcome after rectal cancer surgery. In addition, neoadjuvant therapy was not associated with increased perioperative complications.

Chemoradiation Therapy for Potentially Resectable Gastric Cancer: Clinical Outcomes Among Patients Who Do Not Undergo Planned Surgery  

SciTech Connect

Purpose: We retrospectively analyzed treatment outcomes among resectable gastric cancer patients treated preoperatively with chemoradiation therapy (CRT) but rendered ineligible for planned surgery because of clinical deterioration or development of overt metastatic disease. Methods and Materials: Between 1996 and 2004, 39 patients with potentially resectable gastric cancer received preoperative CRT but failed to undergo surgery. At baseline clinical staging, 33 (85%) patients had T3-T4 disease, and 27 (69%) patients had nodal involvement. Most patients received 45 Gy of radiotherapy with concurrent 5-fluorouracil-based chemotherapy. Twenty-one patients underwent induction chemotherapy before CRT. Actuarial times to local control (LC), distant control (DC), and overall survival (OS) were calculated by the Kaplan-Meier method. Results: The cause for surgical ineligibility was development of metastatic disease (28 patients, 72%; predominantly peritoneal, 18 patients), poor performance status (5 patients, 13%), patient/physician preference (4 patients, 10%), and treatment-related death (2 patients, 5%). With a median follow-up of 8 months (range, 1-95 months), actuarial 1-year LC, DC, and OS were 46%, 12%, and 36%, respectively. Median LC and OS were 11.0 and 10.1 months, respectively. Conclusions: Patients with potentially resectable gastric cancer treated with preoperative CRT are found to be ineligible for surgery principally because of peritoneal progression. Patients who are unable to undergo planned surgery have outcomes comparable to that of patients with advanced gastric cancer treated with chemotherapy alone. CRT provides durable LC for the majority of the remaining life of these patients.

Systematic review of studies investigating sentinel node navigation surgery and lymphatic mapping for gastric cancer.  

PubMed

Evolutions in minimally invasive surgical techniques and advances in sentinel node navigation surgery (SNNS) have had considerable impact on current insights into surgical treatment of gastric cancer. Extensive data on this method of surgical application have accumulated but have been principally derived from single-institute studies. Isosulfan blue and patent blue violet have been the most frequently used dye tracers in the past; however, indocyanine green has now is increasingly popular. The double-tracer method, where dye and radioisotope tracers are used together, seems to be more effective than any single tracer. Among newly emerging adjunct techniques and promising alternative in particular are infrared ray electronic endoscopy, florescence imaging, nanoparticles, and near-infrared technology. Hematoxylin and eosin (H&E) staining is still the method of choice for the detection of sentinel lymph node (SLN) metastases. Immunohistochemical staining can be used to support H&E findings, but the equipment costs of ultrarapid processing systems are currently slowing down their worldwide spread. We believe minimally invasive function-preserving resection of the stomach, together with lymphatic basin dissection navigated by SLNs, can represent the ideal approach for SNNS to detect clinically node-negative early gastric cancer, although this remains to be elucidated. Patients with cT3 or more advanced disease should still be treated by means of standard D2 dissection. PMID:23755853

Circulating tumor cells before and during follow-up after breast cancer surgery.  

PubMed

The presence of circulating tumor cells (CTC) is an independent prognostic factor for progression-free and overall survival for patients with metastatic and newly diagnosed breast cancer. The present study was undertaken to explore whether the presence of CTC before and during follow-up after surgery is associated with recurrence free survival (RFS) and overall survival (OS). In a prospective single center study, CTC were enumerated with the CellSearch system in 30 ml of peripheral blood of 403 stage I-III patients before undergoing surgery for breast cancer (A) and if available 1 week after surgery (B), after adjuvant chemo- and/or radiotherapy or before start of long-term hormonal therapy (C), one (D), two (E) and three (F) years after surgery. Patients were stratified into unfavorable (CTC ?1) and favorable (CTC=0) prognostic groups. >1 CTC in 30 ml blood was detected in 75/403 (19%) at A, 66/367 (18%) at B, 40/263 (15%) at C, 30/235 (12%) at D, 18/144 (11%) at E and 11/83 (13%) at F. RFS and OS was significantly lower for unfavorable CTC as compared to favorable CTC before surgery (p=0.022 and p=0.006), after adjuvant therapy (p<0.001 and p=0.018) and one (p=0.006 and p=0.013) and two (p<0.001 and p=0.045) years after surgery, but not 1 week post-surgery. The presence of CTC in blood drawn pre and one and two years after surgery, but not post-surgery is associated with shorter RFS and OS for stage I-III breast cancer. PMID:25339612

The Role of Secondary Cytoreductive Surgery in Patients with Recurrent Epithelial Ovarian, Tubal, and Peritoneal Cancers: A Comparative Effectiveness Analysis  

PubMed Central

Background. All published reports concerning secondary cytoreductive surgery for relapsed ovarian cancer have essentially been observational studies. However, the validity of observational studies is usually threatened from confounding by indication. We sought to address this issue by using comparative effectiveness methods to adjust for confounding. Methods. Using a prospectively collected administrative health care database in a single institution, we identified 1,124 patients diagnosed with recurrent epithelial, tubal, and peritoneal cancers between 1990 and 2009. Effectiveness of secondary cytoreductive surgery using the conventional Cox proportional hazard model, propensity score, and instrumental variable were compared. Sensitivity analyses for residual confounding were explored using an array approach. Results. Secondary cytoreductive surgery prolonged overall survival with a hazard ratio (95% confidence interval) of 0.76 (range 0.66–0.87), using the Cox proportional hazard model. Propensity score methods produced comparable results: 0.75 (range 0.64–0.86) by nearest matching, 0.73 (0.65–0.82) by quintile stratification, 0.71 (0.65–0.77) by weighting, and 0.72 (0.63–0.83) by covariate adjustment. The instrumental variable method also produced a comparable estimate: 0.75 (range 0.65–0.86). Sensitivity analyses revealed that the true treatment effects may approach the null hypothesis if the association between unmeasured confounders and disease outcome is high. Conclusions. This comparative effectiveness study provides supportive evidence for previous reports that secondary cytoreductive surgery may increase overall survival for patients with recurrent epithelial, tubal, and peritoneal cancers.

The impact of surgically induced ischaemia on protein levels in patients undergoing rectal cancer surgery  

PubMed Central

The goal of targeted therapy has driven a search for markers of prognosis and response to adjuvant therapy. The surgical resection of a solid tumour induces tissue ischaemia and acidosis, both potent mediators of gene expression. This study investigated the impact of colorectal cancer (CRC) surgery on prognostic and predictive marker levels. Tumour expression of thymidylate synthase, thymidine phosphorylase, cyclin A, vascular endothelial growth factor (VEGF), carbonic anhydrase-9, hypoxia inducible factor-1?, and glucose transporter-1 (GLUT-1) proteins was determined before and after rectal cancer surgery. Spectral imaging of tissue sections stained by immunohistochemistry provided quantitative data. Surgery altered thymidylate synthase protein expression (P=0.02), and this correlated with the change in the proliferation marker cyclin A. The expression of hypoxia inducible factor-1?, VEGF, and GLUT-1 proteins was also different following surgery. Colorectal cancer surgery significantly impacts on intratumoral gene expression, suggesting archival specimens may not accurately reflect in situ marker levels. Although rectal cancer was the studied model, the results may be applicable to any solid tumour undergoing extirpation in which molecular markers have been proposed to guide patient therapy.

The role of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of ovarian cancer relapse.  

PubMed

Nowadays the standard clinical management for advanced epithelial ovarian cancer is constituted by primary cytoreductive surgery associated to adjuvant systemic chemotherapy. Even if this first-line chemotherapy shows a high rate of complete responses, the disease recurrences occur especially in stage-III patients. Actually an option for this subset of patients is represented by secondary cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy that represents a promising therapy, having shown positive results in terms of median overall survival, progression free survival and overall survival. However, a much more research is still required especially by prospective randomised trials to improve outcomes in recurrent ovarian cancer. PMID:23980020

Sentinel lymph node biopsy in breast cancer patients with previous breast augmentation surgery.  

PubMed

The number of breast augmentation surgeries (BAS) has increased. Therefore, the number of breast cancer patients with history of BAS has also increased. In this paper, we present two cases of sentinel lymph node biopsy (SLNB) in patients with previous BAS who were diagnosed with breast cancer. The patients were augmented using different approach; the first case was augmented through transaxillary incision, whereas the second case was augmented through periareolar incision. Lymphoscintigraphy (LPG) was performed on the patients 1 day prior to operation, enabling confirmation of lymphatic flow and SLN in both patients. SLNB was successfully performed in both cases. In one patient, SLNB was performed using indocyanine green (ICG) fluorescence and the Photodynamic Eye (PDE) system. Regardless of history of BAS, ICG and PDE system showed lymphatic flow and SLN in real time. LPG and ICG fluorescence were useful methods for SLN detection in patients with previous BAS, being able to confirm lymph flow before operation. Biopsy methods using LPG and PDE system were considered useful for difficult confirmation of lymph flow after breast augmentation. This is the first report of SLNB using ICG and PDE system for patients with previous BAS. PMID:21671037

Surgery for lung metastases from colorectal cancer: the practice examined.  

PubMed

Operations to remove metastases in the lung have become commonplace. In this article, I give a highly critical perspective of a practice that has grown without a secure evidence base, notwithstanding more than 500 articles on the subject. The objectives are mixed and sometimes unclear. The reports are generally in the form of Kaplan-Meier survival analyses but, when challenged on the expected benefit for individuals, clinicians tend to retreat to claims for palliation rather than for 'cure'. Yet the reports include no symptom checklists, quality-of-life measures or patient-reported outcomes. I see at least four distinguishable contexts, defined by cancer types, which deserve to be considered separately: sarcoma; testicular and germ cell tumors; cancers traditionally seen as having an 'oligometastatic' pattern of behavior, such as kidney and thyroid; and the more common solid cancers, such as colorectal and breast cancer. Most surgical series group them together with a tail of one, two or three instances of the less common cancers. The inclusion in these series of all cancer types operated upon adds nothing to knowledge on cancers with low numbers and complicates the analysis for the more common ones. In this article, I will confine the discussion for the main part to colorectal cancer, which is the most common cancer in which pulmonary metastasectomy is practiced. PMID:20477173

Less Radical Surgery for Patient With Early-Stage Cervical Cancer  

PubMed Central

Introduction Surgery in cervical cancer should be used with intention of cure. Radical abdominal trachelectomy is a feasible operation for selected patients with stage I?-1? cervical cancer which fertility can be preserved. Case Report A 30-years-old woman with squamous cell cervical cancer stage (1 A II) diagnosed at September 2011 expressed a wish for fertility-sparing treatment. Radical abdominal hysterectomy and pelvic and para-aortic lymphadenectomy were performed which showed no evidence of lymphatic metastasis. Subsequently, at last follow-up (5 months post-surgery), good oncologic outcomes were found after this procedure. This was the first case of fertility-sparing radical trachelectomy procedures performed at our institution. Conclusions Trachelectomy represents a valuable conservative surgical approach for early stage invasive cervical cancer. PMID:24396586

Urinary concentrations of ADAM 12 from breast cancer patients pre- and post-surgery vs. cancer-free controls: a clinical study for biomarker validation  

PubMed Central

Background The ADAMs (A Disintegrin and Metalloproteinases) are a family of multi-domain, zinc-dependent metalloproteinase enzymes. ADAM 12 has been previously associated with the onset and progression of breast cancer, and elevated levels of ADAM 12 have been previously found in the urine of breast cancer patients. Aims of the current study are: 1) establish the viability of urinary ADAM 12 as a diagnostic marker for breast cancer, and 2) explore the effects of surgical tumor removal on the levels of urinary ADAM 12. Methods A total of 96 patients have been recruited for this study, including 50 patients diagnosed with cancer, and 46 age-matched controls. Commercially available ELISA kits for ADAM 12 were used to quantify the presence and concentration of this enzyme in the urine from cancer patients with ductal carcinoma in situ (DCIS) and invasive breast cancer (IBC) both prior to any treatment and approximately two weeks following surgery, as well as from controls. Results We find no statistically significant differences between the concentrations of ADAM 12 in the urine of breast cancer patients prior to treatment and that of their age-matched controls; however the concentration of ADAM 12, both alone and as a function of urine total protein, are significantly elevated following surgery (p < 0.0001). Patients who underwent a mastectomy have significantly higher urinary ADAM 12 concentrations than those who underwent a lumpectomy (significant at p = 0.0271). Conclusions These findings suggest that urinary ADAM 12 may not correlate directly with the status and stage of breast cancer as previously thought; rather these increases may be a result of tissue injury and inflammation from biopsy and surgical resection. Results of this study may suggest a need for biomarkers to be evaluated carefully in the context of tissue damage. PMID:24690292

Systematic lymphadenectomy in ovarian cancer at second-look surgery: a randomised clinical trial  

PubMed Central

Background: The role of systematic aortic and pelvic lymphadenectomy (SAPL) at second-look surgery in early stage or optimally debulked advanced ovarian cancer is unclear and never addressed by randomised studies. Methods: From January 1991 through May 2001, 308 patients with the International Federation of Gynaecology and Obstetrics stage IA–IV epithelial ovarian carcinoma were randomly assigned to undergo SAPL (n=158) or resection of bulky nodes only (n=150). Primary end point was overall survival (OS). Results: The median operating time, blood loss, percentage of patients requiring blood transfusions and hospital stay were higher in the SAPL than in the control arm (P<0.001). The median number of resected nodes and the percentage of women with nodal metastases were higher in the SAPL arm as well (44% vs 8%, P<0.001 and 24.2% vs 13.3%, P:0.02). After a median follow-up of 111 months, 171 events (i.e., recurrences or deaths) were observed, and 124 patients had died. Sites of first recurrences were similar in both arms. The adjusted risk for progression and death were not statistically different (hazard ratio (HR) for progression=1.18, 95% confidence interval (CI)=0.87–1.59; P=0.29; 5-year progression-free survival (PFS)=40.9% and 53.8% HR for death=1.04, 95% CI=0.733–1.49; P=0.81; 5-year OS=63.5% and 67.4%, in the SAPL and in the control arm, respectively). Conclusion: SAPL in second-look surgery for advanced ovarian cancer did not improve PFS and OS. PMID:22864456

Laparoscopic versus open surgery for the treatment of colorectal cancer: a literature review and recommendations from the Comité de l’évolution des pratiques en oncologie  

PubMed Central

Background Adoption of the laparoscopic approach for colorectal cancer treatment has been slow owing to initial case study results suggesting high recurrence rates at port sites. The use of laparoscopic surgery for colorectal cancer still raises a number of concerns, particularly with the technique’s complexity, learning curve and longer duration. After exploring the scientific literature comparing open and laparoscopic surgery for the treatment of colorectal cancer with respect to oncologic efficacy and short-term outcomes, the Comité de l’évolution des pratiques en oncologie (CEPO) made recommendations for surgical practice in Quebec. Methods Scientific literature published from January 1995 to April 2012 was reviewed. Phase III clinical trials and meta-analyses were included. Results Sixteen randomized trials and 10 meta-analyses were retrieved. Analysis of the literature confirmed that for curative treatment of colorectal cancer, laparoscopy is not inferior to open surgery with respect to survival and recurrence rates. Moreover, laparoscopic surgery provides short-term advantages, including a shorter hospital stay, reduced analgesic use and faster recovery of intestinal function. However, this approach does require a longer operative time. Conclusion Considering the evidence, the CEPO recommends that laparoscopic resection be considered an option for the curative treatment of colon and rectal cancer; that decisions regarding surgical approach take into consideration surgeon experience, tumour stage, potential contraindications and patient expectations; and that laparoscopic resection for rectal cancer be performed only by appropriately trained surgeons who perform a sufficient volume annually to maintain competence.

PubMed Central

Background: Survival from breast cancer in the United Kingdom is lower than in other developed countries. It is unclear to what extent waiting times for curative surgery affect survival. Methods: Using national databases for England (cancer registries, Hospital Episode Statistics and Office of National Statistics), we identified 53?689 women with localised breast cancer, aged ?15 years, diagnosed between 1996 and 2009, who had surgical resection with curative intent within 62 days of diagnosis. We used relative survival and excess risk modelling to determine associations between waiting times and 5-year survival. Results: The median diagnosis to curative surgery waiting time among breast cancer patients was 22 days (interquartile range (IQR): 15–30). Relative survival was similar among women waiting between 25 and 38 days (RS: 93.5% 95% CI: 92.8–94.2%), <25 days (RS: 93.0% 95% CI: 92.5–93.4%) and between 39 and 62 days (RS: 92.1% 95% CI: 90.8–93.4%). There was little evidence of an increase in excess mortality with longer waiting times (excess hazard ratio (EHR): 1.06; 95% CI: 0.88–1.27 comparing waiting times 39-62 with 25–38 days). Excess mortality was associated with age (EHR 65–74 vs 15–44 year olds: 1.23; 95% CI: 1.07–1.41) and deprivation (EHR most vs least deprived: 1.28; 95% CI: 1.09–1.49), but waiting times did not explain these differences. Conclusion: Within 62 days of diagnosis, decreasing waiting times from diagnosis to surgery had little impact on survival from localised breast cancer. PMID:23799851

The Role of Surgery for Asymptomatic Primary Tumors in Unresectable Stage IV Colorectal Cancer  

PubMed Central

There are still debates regarding the appropriate primary treatment policy for asymptomatic primary colorectal lesions in cases of unresectable metastatic colorectal cancer. Even though there are patients with asymptomatic primary tumors when starting chemotherapy, those patients may still undergo surgery due to complications related to primary tumors in the middle of chemotherapy; therefore, controversy exists regarding surgical resection of primary colorectal lesions in cases where symptoms are absent when making a diagnosis. Thus, based on the published literature, we discuss opinions that prefer first-line surgery for primary tumors as well as opinions favoring first-line chemotherapy for treating unresectable synchronous metastatic colorectal cancer. Although the upfront chemotherapy including targeted agents is suggested as an effective treatment in recent years, the first line surgery has been a preferred treatment for decades. The first line surgery is beneficial to prolong the survival duration given the retrospective analysis of randomized trial data. So far, no prospective comparison study has only focused on the first-line treatment modality; thus, future clinical studies focusing on the survival duration and the quality of life should be performed as soon as possible. Furthermore, at this point, multidisciplinary team approaches would be helpful in finding the appropriate therapy. Regardless of symptoms, the performance status and the tumor burden should be taken into consideration as well. In case of surgical resection, minimally invasive surgery, such as laparoscopic surgery, is recommended. PMID:23700570

Robotic surgery for rectal cancer: Current immediate clinical and oncological outcomes  

PubMed Central

Laparoscopic rectal surgery continues to be a challenging operation associated to a steep learning curve. Robotic surgical systems have dramatically changed minimally invasive surgery. Three-dimensional, magnified and stable view, articulated instruments, and reduction of physiologic tremors leading to superior dexterity and ergonomics. Therefore, robotic platforms could potentially address limitations of laparoscopic rectal surgery. It was aimed at reviewing current literature on short-term clinical and oncological (pathological) outcomes after robotic rectal cancer surgery in comparison with laparoscopic surgery. A systematic review was performed for the period 2002 to 2014. A total of 1776 patients with rectal cancer underwent minimally invasive robotic treatment in 32 studies. After robotic and laparoscopic approach to oncologic rectal surgery, respectively, mean operating time varied from 192-385 min, and from 158-297 min; mean estimated blood loss was between 33 and 283 mL, and between 127 and 300 mL; mean length of stay varied from 4-10 d; and from 6-15 d. Conversion after robotic rectal surgery varied from 0% to 9.4%, and from 0 to 22% after laparoscopy. There was no difference between robotic (0%-41.3%) and laparoscopic (5.5%-29.3%) surgery regarding morbidity and anastomotic complications (respectively, 0%-13.5%, and 0%-11.1%). Regarding immediate oncologic outcomes, respectively among robotic and laparoscopic cases, positive circumferential margins varied from 0% to 7.5%, and from 0% to 8.8%; the mean number of retrieved lymph nodes was between 10 and 20, and between 11 and 21; and the mean distal resection margin was from 0.8 to 4.7 cm, and from 1.9 to 4.5 cm. Robotic rectal cancer surgery is being undertaken by experienced surgeons. However, the quality of the assembled evidence does not support definite conclusions about most studies variables. Robotic rectal cancer surgery is associated to increased costs and operating time. It also seems to be associated to reduced conversion rates. Other short-term outcomes are comparable to conventional laparoscopy techniques, if not better. Ultimately, pathological data evaluation suggests that oncologic safety may be preserved after robotic total mesorectal excision. However, further studies are required to evaluate oncologic safety and functional results. PMID:25339823

What Is the Problem in Clinical Application of Sentinel Node Concept to Gastric Cancer Surgery?  

PubMed Central

More than ten years have passed since the sentinel node (SN) concept for gastric cancer surgery was first discussed. Less invasive modified surgical approaches based on the SN concept have already been put into practice for malignant melanoma and breast cancer, however the SN concept is not yet placed in a standard position in gastric cancer surgery even after two multi-institutional prospective clinical trials, the Japan Clinical Oncology Group trial (JCOG0302) and the Japanese Society for Sentinel Node Navigation Surgery (SNNS) trial. What is the problem in the clinical application of the SN concept to gastric cancer surgery? There is no doubt that we need reliable indicator(s) to determine with certainty the absence of metastasis in the lymph nodes in order to avoid unnecessary lymphadenectomy. There are several matters of debate in performing the actual procedure, such as the type of tracer, the site of injection, how to detect and harvest, how to detect metastases of SNs, and learning period. These issues have to be addressed further to establish the most suitable procedure. Novel technologies such as indocyanine green (ICG) fluorescence imaging and one-step nucleic acid amplification (OSNA) may overcome the current difficulties. Once we know what the problems are and how to tackle them, we can pursue the goal. PMID:22500258

Ultrasound- and MR-guided focused ultrasound surgery for prostate cancer  

PubMed Central

Prostate cancer (PC) is one of the most frequently diagnosed cancers in men. There are a number of treatment options for PC with a different therapeutic approach between USA and Europe. Radical prostatectomy is one of the most used therapies but focal gland therapy is an emerging approach, especially for localized tumors. In this scenario, high intensity focused ultrasound (HIFU) has been incorporated in certain medical association guidelines. HIFU has been employed for about 10 years especially for localized PC. Results are promising with a 5-year biochemical survival rate ranging from 45% to 84%. Collateral events are rare and HIFU retreatment is not common. Magnetic resonance guided focused ultrasound surgery (MRgFUS) was recently presented as a method for ablation with focused ultrasound under magnetic resonance imaging guidance. It has the advantage of improved targeting and real time temperature monitoring but only a few studies have been conducted with human patients. The aim of this review is to describe the current status of HIFU and MRgFUS in the therapy of PC. PMID:22778876

Intrusive thoughts and quality of life among men with prostate cancer before and three months after surgery  

PubMed Central

Background Sudden, unwelcome and repetitive thoughts about a traumatic event – intrusive thoughts – could relate to how men assess their quality of life after prostate-cancer diagnosis. We aimed to study the prevalence of intrusive thoughts about prostate cancer and their association with quality-of-life outcomes before and after radical prostatectomy. Methods During the first year of the LAPPRO-trial, 971 men scheduled for radical prostatectomy were prospectively included from 14 urological centers in Sweden. Of those, 833 men responded to two consecutive study-specific questionnaires before and three months after surgery (participation rate 86%). The association of intrusive thoughts with three quality-of-life outcomes, i.e. self-assessed quality of life, depressive mood and waking up with anxiety was estimated by prevalence ratios that were calculated, together with a 95% confidence interval, at the same time-point as well as over time. Fisher’s exact-test was used to analyze differences between respondents and non-respondents. Wilcoxon signed-ranks and Cochran-Armitage trend tests were used for analysis of change over time. To validate new questions on intrusive thoughts, written answers to open-ended questions were read and analyzed by qualitative content analysis. Results Before surgery, 603 men (73%) reported negative intrusive thoughts about their cancer at some time in the past month and 593 men (59%) reported such thoughts three months after surgery. Comparing those reporting intrusive thoughts at least weekly or once a week before surgery with those who did not, the prevalence ratio (95% confidence interval), three months after surgery, for waking up in the middle of the night with anxiety was 3.9 (2.7 to 5.5), for depressed mood 1.8 (1.6 to 2.1) and for impaired self-assessed quality of life 1.3 (1.2 to 1.5). Conclusion The prevalence of negative intrusive thoughts about prostate cancer at the time of surgery associates with studied quality-of-life outcomes three months later.

Breast cancer surgery: an historical narrative. Part I. From prehistoric times to Renaissance.  

PubMed

Cancer was known as a disease since prehistoric times. Management of breast cancer evolved slowly through centuries in the ancient world up to the Renaissance. This period is marked by the absence of any scientifically verifiable understanding of the true nature of cancer and its natural history and consequently by a lack of effective treatment. Breast has been considered as a symbol of femininity, fertility and beauty. Hippocrates proposed that breast cancer, among other neoplasms, was a 'systemic disease' caused by an excess of black bile. The humoral theory was further supported by Galen and dominated for centuries in medicine. Fulguration and breast amputation by using various instruments to achieve a rapid operation were widely used up to the 18th century. The Renaissance was a revolutionary period, since it stimulated medical practice; at that time physicians started to scientifically study medicine. Vesalius greatly contributed in the advancement of surgery, and he vigorously opposed Galen's doctrines. Many great surgeons of that time (including Paré, Cabrol, Servetto, Scultetus, Tulp, Fabry von Hilded, etc.) advanced the science of surgery. Interestingly, Bartoleny Gabrol (1590) in Montpellier advocated radical mastectomy, which was popularised by Halsted, 300 years later. However, the lack of anaesthesia and the problem of wound infections (due to the lack of the aseptic techniques) generated significance and often problems for the surgeons of that time. Surgery was often 'heroic' but primitive and even inhumane by current standards. Therapeutic nihilism was the prevailing altitude regarding breast cancer, at least among the vast majority of surgeons. PMID:19674074

The dark side of the moon: Impact of moon phases on long-term survival, mortality and morbidity of surgery for lung cancer  

PubMed Central

Objective Superstition is common and causes discomfiture or fear, especially in patients who have to undergo surgery for cancer. One superstition is, that moon phases influence surgical outcome. This study was performed to analyse lunar impact on the outcome following lung cancer surgery. Methods 2411 patients underwent pulmonary resection for lung cancer in the past 30 years at our institution. Intra-and postoperative complications as well as long-term follow-up data were entered in our lung-cancer database. Factors influencing mortality, morbidity and survival were analyzed. Results Rate of intra-operative complications as well as rate of post-operative morbidity and mortality was not significantly affected by moon phases. Furthermore, there was no significant impact of the lunar cycle on long-term survial. Conclusion In this study there was no evidence that outcome of surgery for lung cancer is affected by the moon. These results may help the physician to quite the mind of patients who are somewhat afraid of wrong timing of surgery with respect to the moon phases. However, patients who strongly believe in the impact of moon phase should be taken seriously and correct timing of operations should be conceded to them as long as key-date scheduling doesn't constrict evidence based treatment regimens.

External validation of nomograms for predicting cancer-specific mortality in penile cancer patients treated with definitive surgery.  

PubMed

Using a population-based cancer registry, Thuret et al. developed 3 nomograms for estimating cancer-specific mortality in men with penile squamous cell carcinoma. In the initial cohort, only 23.0% of the patients were treated with inguinal lymphadenectomy and had pN stage. To generalize the prediction models in clinical practice, we evaluated the performance of the 3 nomograms in a series of penile cancer patients who were treated with definitive surgery. Clinicopathologic information was obtained from 160 M0 penile cancer patients who underwent primary tumor excision and regional lymphadenectomy between 1990 and 2008. The predicted probabilities of cancer-specific mortality were calculated from 3 nomograms that were based on different disease stage definitions and tumor grade. Discrimination, calibration, and clinical usefulness were assessed to compare model performance. The discrimination ability was similar in nomograms using the TNM classification or American Joint Committee on Cancer staging (Harrell's concordance index = 0.817 and 0.832, respectively), whereas it was inferior for the Surveillance, Epidemiology and End Results staging (Harrell's concordance index = 0.728). Better agreement with the observed cancer-specific mortality was shown for the model consisting of TNM classification and tumor grade, which also achieved favorable clinical net benefit, with a threshold probability in the range of 0 to 42%. The nomogram consisting of TNM classification and tumor grading was shown to have better performance for predicting cancer-specific mortality in penile cancer patients who underwent definitive surgery. Our data support the integration of this model in decision-making and trial design. PMID:24559854

Definition of compartment-based radical surgery in uterine cancer: modified radical hysterectomy in intermediate/high-risk endometrial cancer using peritoneal mesometrial resection (PMMR) by M Höckel translated to robotic surgery  

PubMed Central

Background The technique of compartment-based radical hysterectomy was originally described by M Höckel as total mesometrial resection (TMMR) for standard treatment of stage I and II cervical cancer. However, with regard to the ontogenetically-defined compartments of tumor development (Müllerian) and lymph drainage (Müllerian and mesonephric), compartments at risk may also be defined consistently in endometrial cancer. This is the first report in the literature on the compartment-based surgical approach to endometrial cancer. Peritoneal mesometrial resection (PMMR) with therapeutic lymphadenectomy (tLNE) as an ontogenetic, compartment-based oncologic surgery could be beneficial for patients in terms of surgical radicalness as well as complication rates; it can be standardized for compartment-confined tumors. Supported by M Höckel, PMMR was translated to robotic surgery (rPMMR) and described step-by-step in comparison to robotic TMMR (rTMMR). Methods Patients (n?=?42) were treated by rPMMR (n?=?39) or extrafascial simple hysterectomy (n?=?3) with/without bilateral pelvic and/or periaortic robotic therapeutic lymphadenectomy (rtLNE) for stage I to III endometrial cancer, according to International Federation of Gynecology and Obstetrics (FIGO) classification. Tumors were classified as intermediate/high-risk in 22 out of 40 patients (55%) and low-risk in 18 out of 40 patients (45%), and two patients showed other uterine malignancies. In 11 patients, no adjuvant external radiotherapy was performed, but chemotherapy was applied. Results No transition to open surgery was necessary. There were no intraoperative complications. The postoperative complication rate was 12% with venous thromboses, (n?=?2), infected pelvic lymph cyst (n?=?1), transient aphasia (n?=?1) and transient dysfunction of micturition (n?=?1). The mean difference in perioperative hemoglobin concentrations was 2.4 g/dL (± 1.2 g/dL) and one patient (2.4%) required transfusion. During follow-up (median 17 months), one patient experienced distant recurrence and one patient distant/regional recurrence of endometrial cancer (4.8%), but none developed isolated locoregional recurrence. There were two deaths from endometrial cancer during the observation period (4.8%). Conclusions We conclude that rPMMR and rtLNE are feasible and safe with regard to perioperative morbidity, thus, it seems promising for the treatment of intermediate/high-risk endometrial cancer in terms of surgical radicalness and complication rates. This could be particularly beneficial for morbidly obese and seriously ill patients. PMID:23947937

Endoscopic laser scalpel for head and neck cancer surgery  

NASA Astrophysics Data System (ADS)

Minimally invasive surgical (MIS) techniques, such as laparoscopic surgery and endoscopy, provide reliable disease control with reduced impact on the function of the diseased organ. Surgical lasers can ablate, cut and excise tissue while sealing small blood vessels minimizing bleeding and risk of lymphatic metastases from tumors. Lasers with wavelengths in the IR are readily absorbed by water causing minimal thermal damage to adjacent tissue, ideal for surgery near critical anatomical structures. MIS techniques have largely been unable to adopt the use of lasers partly due to the difficulty in bringing the laser into the endoscopic cavity. Hollow waveguide fibers have been adapted to bring surgical lasers to endoscopy. However, they deliver a beam that diverges rapidly and requires careful manipulation of the fiber tip relative to the target. Thus, the principal obstacle for surgical lasers in MIS procedures has been a lack of effective control instruments to manipulate the laser in the body cavity and accurately deliver it to the targeted tissue. To overcome this limitation, we have designed and built an endoscopic laser system that incorporates a miniature dual wedge beam steering device, a video camera, and the control system for remote and /or robotic operation. The dual wedge Risley device offers the smallest profile possible for endoscopic use. Clinical specifications and design considerations will be presented together with descriptions of the device and the development of its control system.

A case of anaphylactic shock attributed to latex allergy during gastric cancer surgery  

PubMed Central

Latex allergy is a known cause of allergic contact dermatitis. It produces mild symptoms, including skin rash and itching, which usually subside in a few days. However, latex allergy can also induce anaphylaxis, a severe type I hypersensitivity reaction that can cause urticaria, angioedema, hypotension, tachycardia, and bronchospasm. We report a case of anaphylactic shock during gastric cancer surgery in a patient with no previous allergic history. Surgery was suspended when hypotension, tachycardia, and wheezing developed. A thorough workup revealed that the patient had a latex allergy. The patient subsequently underwent curative gastrectomy performed with latex-free procedures. PMID:22319734

Is Early Oral Feeding after Gastric Cancer Surgery Feasible? A Systematic Review and Meta-Analysis of Randomized Controlled Trials  

PubMed Central

Aim To assess the feasibility and safety of early oral feeding (EOF) after gastrectomy for gastric cancer through a systematic review and meta-analysis based on randomized controlled trials. Methods A literature search in PubMed, Embase, Web of Science and Cochrane library databases was performed for eligible studies published between January 1995 and March 2014. Systematic review was carried out to identify randomized controlled trials comparing EOF and traditional postoperative oral feeding after gastric cancer surgery. Meta-analyses were performed by either a fixed effects model or a random effects model according to the heterogeneity using RevMan 5.2 software. Results Six studies remained for final analysis. Included studies were published between 2005 and 2013 reporting on a total of 454 patients. No significant differences were observed for postoperative complication (RR?=?0.95; 95%CI, 0.70 to 1.29; P?=?0.75), the tolerability of oral feeding (RR?=?0.98; 95%CI, 0.91 to 1.06; P?=?0.61), readmission rate (RR?=?1; 95%CI, 0.30 to 3.31; P?=?1.00) and incidence of anastomotic leakage (RR?=?0.31; 95%CI, 0.01 to 7.30; P?=?0.47) between two groups. EOF after gastrectomy for gastric cancer was associated with significant shorter duration of the hospital stay (WMD?=??2.36; 95%CI, ?3.37 to ?1.34; P<0.0001) and time to first flatus (WMD?=??19.94; 95%CI, ?32.03 to ?7.84; P?=?0.001). There were no significant differences in postoperative complication, tolerability of oral feeding, readmission rates, duration of hospital stay and time to first flatus among subgroups stratified by the time to start EOF or by partial and total gastrectomy or by laparoscopic and open surgery. Conclusions The result of this meta-analysis showed that EOF after gastric cancer surgery seems feasible and safe, even started at the day of surgery irrespective of the extent of the gastric resection and the type of surgery. However, more prospective, well-designed multicenter RCTs with more clinical outcomes are needed for further validation. PMID:25397686

[Two cases of bronchiolitis obliterans organizing pneumonia (BOOP) induced radiotherapy after surgery of breast cancer].  

PubMed

We report two cases of bronchiolitis obliterans organizing pneumonia (BOOP) induced radiotherapy after surgery of breast cancer. One of the patients was a 58-year-old woman. She underwent a conserving surgery for bilateral breast cancers, and received radiation therapy to the remaining part of bilateral breasts. Two months after the termination of irradiation, cough, fever and general fatigue developed. We clinically diagnosed this case as BOOP after radiation therapy. After initiation of oral steroid therapy, the clinical symptoms and radiographic findings disappeared. Another patient was a 57-year-old woman. She underwent radical mastectomy for right breast cancer. A month after the operation, she suffered from local recurrence, so radiation therapy to the thoracic wall was performed. After irradiation, resection of the thoracic wall lesion was performed because of malignancy from local skin biopsy specimen. Two months after the termination of irradiation, cough, dyspnea and fever developed. We clinically diagnosed this case as radiation-induced BOOP by BAL and TBLB findings. After an initiation of steroid therapy, the clinical symptoms and radiographic findings disappeared. It is important to be aware of BOOP as a complication in the patient who was given radiation after surgery of breast cancer. PMID:21224711

The use of CT findings to predict extent of tumor at primary surgery for ovarian cancer  

PubMed Central

Background High tumor dissemination (HTD) is a major risk factor for serious morbidity after primary ovarian cancer (OC) surgery, particularly in medically compromised patients. We performed a pilot study of whether CT findings could predict extent of disease and surgical complexity necessary in advanced OC. Methods Preoperative CT images for patients with advanced OC from 1997–2003 were evaluated for rigorously defined disease-related findings and compared to both the findings at exploration and the required surgical procedures. Associations were assessed by the chi-square test. Results Forty-six cases met inclusion criteria. Mean age was 66.4 y, and 76% had residual disease (RD) 1cm or less. CT and surgical findings correlated (sensitivity/specificity) as follows: diaphragm disease (48%/100%); surface liver (100%/93%); omental cake (72%/65%); any sigmoid involvement (54%/100%); ascites (44%/100%); extra-pelvic large bowel involvement (29%/91%). When diaphragm disease and omental cake were present, HTD was found in all cases (positive predictive value and specificity=100%, sensitivity 48%). For CT findings of liver, large bowel and spleen involvement there was a strong trend toward resection (p=0.001, p=0.06 and p=0.06, respectively). Conclusions The findings of diaphragm disease and omental cake on CT scan are highly predictive for high tumor dissemination (HTD) and thus likelihood of extensive surgery required to achieve low residual disease. In addition, multiple CT findings correlate strongly with the need for higher surgical complexity which should facilitate preoperative planning and/or triage to specialized centers. These preliminary data suggest specific CT findings can be used to optimize treatment planning. PMID:23672930

Transoral laser surgery for recurrent glottic cancer after radiotherapy: oncologic and functional outcomes.  

PubMed

Primary radiotherapy (RT) has been successfully employed for treatment of early glottic cancer for the past half century. However, local recurrences still occur in 5-35% of patients. Salvage options for persistent/recurrent glottic cancer include total laryngectomy, open neck partial laryngectomies (ONPLs) and transoral laser surgery (TLS). We performed a retrospective chart review of 35 patients with glottic squamous cell carcinoma previously submitted to RT and managed by TLS at the Department of Otorhinolaryngology - Head and Neck Surgery of the University of Brescia, Italy, from 1995 to 2009. Oncologic outcomes were estimated using the Kaplan-Meier method, and separately calculated for the entire cohort of patients (n = 35) and for patients with true persistent/recurrent disease (n = 30), thus excluding the second primary tumours (n = 5). Hospitalization time and complications were obtained by chart review. Functional outcomes of a subgroup of 10 patients in terms of speech and swallowing were analyzed by the Voice Handicap Index (VHI), GRBAS scale, Multi Dimensional Voice Program (MDVP), M.D. Anderson Dysphagia Inventory (MDADI) questionnaire, videoendoscopy (VEES), and videofluoroscopy (VFS) of swallowing (both graded according to Donzelli's scale), and compared to a cohort of 10 patients matched for age, gender and pT category, treated by the same team of surgeons by TLS as a primary treatment. The types of resection used were: 18 Type III, 1 Type IV, and 16 Type V cordectomies. Postoperative staging was 16 rpT1a, 17 rpT2, and 2 rpT3. The 5-year overall survival for the entire series was 91%. Five-year disease-specific survival, local control with laser alone, and organ preservation rates were 94%, 84% and 87%, respectively. Among the variables tested by univariate analysis, for the entire cohort of patients the pT category had a statistically significant impact on local control with laser alone. Anterior transcommissural extension had a borderline statistical impact on disease-specific survival, while it was clearly significant on overall survival. The status of surgical margins and presence of recurrence after TLS statistically influenced both organ preservation and local control with laser alone. The mean values of VHI, MDADI, and MDVP did not show any statistically significant difference between irradiated and non-irradiated patients. The same was true for GRBAS, VEES, and VFS. This series confirms that TLS after RT failure can be considered a successful surgical option in selected early recurrences, with functional outcomes comparable to those observed after TLS as a primary treatment, and much better than those classically described after ONPLs.

Motor pattern of the left colon before and after surgery for rectal cancer: possible implications in other disorders.  

PubMed Central

The motility of the descending colon was studied in nine patients before and after resection of the rectum for cancer. This operation parasympathectomises and generally also sympathectomises the remaining left colon. Motor activity was significantly reduced by sleep before and after surgery. There was also a reduction in awake motility after surgery which is attributed to extrinsic denervation. The reduced motility may explain the increased frequency of motions passed after surgery.

OVSCORE - a validated score to identify ovarian cancer patients not suitable for primary surgery  

PubMed Central

Following primary debulking surgery, the presence of a residual tumor mass is one of the most important prognostic factors in ovarian cancer. In a previous study, we established the OVSCORE, an algorithm to predict surgical outcome, based on the clinical factors of nuclear grading and ascitic fluid volume, plus the cancer biomarkers, kallikrein-related peptidases (KLKs), KLK6 and KLK13. In the present study, OVSCORE performance was tested in an independent ovarian cancer patient cohort consisting of 87 patients. The impact of KLKs, KLK5, 6, 7 and 13 and other clinical factors on patient prognosis and outcome was also evaluated. The OVSCORE proved to be a strong and statistically significant predictor of surgical success in terms of area under the receiver operating characteristic curve (ROC AUC, 0.777), as well as positive and negative predictive value in this independent study group. KLK6 and 13 individually did not show clinical relevance in this cohort, but two other KLKs, KLK5 and KLK7, were associated with advanced FIGO stage, higher nuclear grade and positive lymph node status. In the multivariate Cox regression analysis for overall survival (OS), KLK7 had a protective impact on OS. This study confirms the role of KLKs in ovarian cancer for surgical success and survival, and validates the novel OVSCORE algorithm in an independent collective. As a key clinical application, the OVSCORE could aid gynecological oncologists in identifying those ovarian cancer patients unlikely to benefit from radical surgery who could be candidates for alternative therapeutic approaches.

The use of somatostatin analogs is a new conservative therapeutic approach for the treatment of chyle fistulas developing after thyroid cancer surgery. The combination therapy with a total parenteral nutrition should avoid the high morbidity of a re-intervention with an uncertain outcome. This promising trend is supported by the present case report of a chyle leak occurring after total thyroidectomy with central and lateral neck dissection for a papillary carcinoma, which was treated successfully without immediate or distant sequelae.

Oncologic Outcomes of Surgery in T3 Prostate Cancer: Experience of a Single Tertiary Center  

PubMed Central

Aim. The aim of this study is to present the oncologic outcomes and to determine the prognostic factors of overall survival (OS), cancer-specific survival (CSS), disease-progression-free survival (DPFS), and biochemical-progression-free survival (BPFS) after surgery for pT3 prostate cancer (PCa). Methods. Between 2002 and 2007, a pT3 stage after radical prostatectomy was detected in 182 patients at our institution. The Kaplan-Meier analysis was used to calculate OS, CSS, DPFS, and BPFS. Cox regression was used to identify predictive factors of survival. Results. pT3a was detected in 126 (69%) and pT3b in 56 (31%) of cases. Five-year OS, CSS, DPFS, and BPFS rates were 90.7%, 94%, 91.8%, and 48.4%, respectively. Survival was significantly different when comparing pT3a to pT3b groups. The 5-year OS, CSS, DPFS, and BPFS were 96% versus 72%, 98% versus 77%, 97.3% versus 79.3%, and 60% versus 24.2%, respectively. Specimen Gleason score was the most significant predictor of OS, CSS, DPFS, and BPFS. The risk of death increased up to 3-fold when a Gleason score 8–10 was present at the final pathology. Conclusions. Radical prostatectomy may offer very good CSS, OS, DPFS, and BPFS rates in pT3a PCa. However, outcomes in patients with pT3b or specimen Gleason ?8 were significantly worse, suggesting the need for multimodality treatment in those cases. PMID:22216025

Incisional Surgical Site Infection after Elective Open Surgery for Colorectal Cancer  

PubMed Central

Background. The purpose of this study was to clarify the incidence and risk factors for incisional surgical site infections (SSI) in patients undergoing elective open surgery for colorectal cancer. Methods. We conducted prospective surveillance of incisional SSI after elective colorectal resections performed by a single surgeon for a 1-year period. Variables associated with infection, as identified in the literature, were collected and statistically analyzed for their association with incisional SSI development. Results. A total of 224 patients were identified for evaluation. The mean patient age was 67 years, and 120 (55%) were male. Thirty-three (14.7%) patients were diagnosed with incisional SSI. Multivariate analysis suggested that incisional SSI was independently associated with TNM stages III and IV (odds ratio [OR], 2.4) and intraoperative hypotension (OR, 3.4). Conclusions. The incidence of incisional SSI in our cohort was well within values generally reported in the literature. Our data suggest the importance of the maintenance of intraoperative normotension to reduce the development of incisional SSI. PMID:24800067

HOSPITAL-LEVEL VARIATION IN THE QUALITY OF UROLOGIC CANCER SURGERY  

PubMed Central

Background Unexplained variation in outcomes after common surgeries raises concerns about the quality and appropriateness of surgical care. Understanding variation in surgical outcomes may identify processes that could affect the quality of surgical and postoperative care. We sought to examine hospital-level variation in outcomes following inpatient urologic oncology procedures. Methods We identified subjects that underwent radical cystectomy, radical nephrectomy, and radical prostatectomy from the Washington State Comprehensive Hospital Abstract Reporting System (CHARS) for the years 2003–2007. We measured postoperative length of stay (LOS) and classified LOS exceeding the 75th percentile as prolonged, the occurrence of Agency for Healthcare Quality Patient Safety Indicators (PSIs), readmissions, and death. We adjusted for patient age and comorbidity in random effects multilevel multivariable models that assessed hospital-level outcomes. Results We identified 853 cystectomy subjects from 37 hospitals, 3,018 nephrectomy subjects from 51 hospitals, and 8,228 prostatectomy subjects from 51 hospitals. Complications captured by PSIs were rare. Hospital-level variation was most profound for LOS outcomes after nephrectomy and prostatectomy (8.1% and 26.7% of variance in prolonged LOS, respectively), thromboembolic events after nephrectomy (8.0% of variance), and mortality after cystectomy (7.1% of variance). Conclusions Hospital-level variation confounds the care of urologic cancer patients in the state of Washington. Transparent reporting of surgical outcomes and local quality improvement initiatives should be considered to ameliorate the observed variation and improve the quality of cystectomy, nephrectomy, and prostatectomy care.

Hypofractionated radiotherapy after conservative surgery for breast cancer: analysis of acute and late toxicity  

PubMed Central

Background A variety of hypofractionated radiotherapy schedules has been proposed after breast conserving surgery in the attempt to shorten the overall treatment time. The aim of the present study is to assess acute and late toxicity of using daily fractionation of 2.25 Gy to a total dose of 45 Gy to the whole breast in a mono-institutional series. Methods Eighty-five women with early breast cancer were assigned to receive 45 Gy followed by a boost to the tumour bed. Early and late toxicity were scored according to the Radiation Therapy Oncology Group criteria. For comparison, a group of 70 patients with similar characteristics and treated with conventional fractionation of 2 Gy to a total dose of 50 Gy in 25 fractions followed by a boost, was retrospectively selected. Results Overall median treatment duration was 29 days for hypofractionated radiotherapy and 37 days for conventional radiotherapy. Early reactions were observed in 72/85 (85%) patients treated with hypofractionation and in 67/70 (96%) patients treated with conventional fractionation (p = 0.01). Late toxicity was observed in 8 patients (10%) in the hypofractionation group and in 10 patients (15%) in the conventional fractionation group, respectively (p = 0.4). Conclusions The hypofractionated schedule delivering 45 Gy in 20 fractions shortened the overall treatment time by 1 week with a reduction of skin acute toxicity and no increase of late effects compared to the conventional fractionation. Our results support the implementation of hypofractionated schedules in clinical practice. PMID:21092288

Management of postoperative nausea and vomiting in women scheduled for breast cancer surgery.  

PubMed

Breast cancer surgery performed under general anesthesia is associated with a high incidence of postoperative nausea and vomiting (PONV). A number of approaches are available for the management of PONV after breast cancer surgery. First, the risk factors related to patient characteristics, surgical procedure, anesthetic technique, and postoperative care can be reduced. More specifically, the use of propofol-based anesthesia can reduce the incidence of PONV. Secondly, a wide range of prophylactic antiemetics, including butyrophenones (droperidol), benzamides (metoclopramide), glucocorticoids (dexamethasone), clonidine, a small dose of propofol, and serotonin receptor (SR) antagonists (ondansetron, granisetron, tropisetron, dolasetron, ramosetron, and palonosetron), are available for preventing PONV. Thirdly, antiemetic therapy combined with granisetron and droperidol or dexamethasone, and a multimodal management strategy which includes a package consisting of dexamethasone, total intravenous anesthesia with propofol, and ondansetron are highly effective in preventing PONV. Unfortunately, the use of glucocorticoids and SR antagonists for preventing PONV is not permitted in Japan according to national health insurance guidelines. Fourth, electro-acupoint stimulation at the P6 point (Nei-Guwan) as a non-pharmacologic therapy is as effective as ondansetron for preventing PONV. Knowledge of the risk factors for PONV, antiemetics, and a non-pharmacologic approach are needed for the management of PONV in women undergoing breast cancer surgery. PMID:21964679

EnROL: A multicentre randomised trial of conventional versus laparoscopic surgery for colorectal cancer within an enhanced recovery programme  

PubMed Central

Background During the last two decades the use of laparoscopic resection and a multimodal approach known as an enhanced recovery programme, have been major changes in colorectal perioperative care. Clinical outcome improves using laparoscopic surgery to resect colorectal cancer but until recently no multicentre trial evidence had been reported regarding whether the benefits of laparoscopy still exist when open surgery is optimized within an enhanced recovery programme. The EnROL trial (Enhanced Recovery Open versus Laparoscopic) examines the hypothesis that laparoscopic surgery within an enhanced recovery programme will provide superior postoperative outcomes when compared to conventional open resection of colorectal cancer within the same programme. Methods/design EnROL is a phase III, multicentre, randomised trial of laparoscopic versus open resection of colon and rectal cancer with blinding of patients and outcome observers to the treatment allocation for the first 7?days post-operatively, or until discharge if earlier. 202 patients will be recruited at approximately 12 UK hospitals and randomised using minimization at a central computer system in a 1:1 ratio. Recruiting surgeons will previously have performed >100 laparoscopic colorectal resections and >50 open total mesorectal excisions to minimize conversion. Eligible patients are those suitable for elective resection using either technique. Excluded patients include: those with acute intestinal obstruction and patients in whom conversion from laparoscopic to open procedure is likely. The primary outcome is physical fatigue as measured by the physical fatigue domain of the multidimensional fatigue inventory 20 (MFI-20) with secondary outcomes including postoperative hospital stay; complications; reoperation and readmission; quality of life indicators; cosmetic assessments; standardized performance indicators; health economic analysis; the other four domains of the MFI-20. Pathological assessment of surgical quality will also be undertaken and compliance with the enhanced recovery programme will be recorded for all patients. Discussion Should this trial demonstrate that laparoscopic surgery confers a significant clinical and/or health economic benefit this will further support the transition to this type of surgery, with implications for the training of surgeons and resource allocation.

Volumes of cancer surgery for breast, colorectal and ovarian cancer 1992-97: is there evidence of increasing sub-specialization by surgeons?  

PubMed Central

The ‘Calman–Hine Report’ (1995) recommended that cancer surgery should be limited to ‘high-volume’ consultants. Through an analysis of 5 years of Hospital Episode Statistics for the West Midlands region (1992–1997), we have investigated whether there is evidence of increasing numbers of patients with breast, colorectal or ovarian cancer being treated by high throughput, i.e. sub-specialist surgeons, who carry out more than a threshold level of primary cancer resections annually. The proportion of cases treated by the high-volume breast, colorectal and ovarian cancer surgeons increased annually during the 5 years. The absolute number of consultant firms who undertook breast cancer resections reduced during the 5 years; but the number doing colorectal and ovarian surgery increased. Throughout the 5 years, half of the ovarian cancer resections were carried out by consultant firms who did very few procedures – less than 5 of these procedures annually. The relatively high case-load, the elective nature of breast cancer surgery and an early policy change have undoubtedly facilitated the move towards sub-specialization. The weaker trends for colorectal and ovarian cancer surgery suggest continued monitoring is required to ensure that there is a reduction in the proportion of people treated by surgeons who undertake few cancer resections annually. © 2001 Cancer Research Campaign www.bjcancer.com PMID:11355939

Clavicular osteomyelitis: a rare complication after surgery for head and neck cancer.  

PubMed

Clavicular osteomyelitis (COM) is a rarely described disease entity, occurring especially after head and neck surgery. We herein report the ninth case according to the English language literature and describe the pertinent diagnostic and therapeutic measures to treat this complication. A 63-year-old Caucasian male underwent total laryngectomy and partial pharyngectomy for a post-radiotherapy recurrence of a T2 hypopharyngeal cancer. He presented multiple systemic (cardiovascular problems, previous pneumonectomy, malnutrition) and local-regional (previous radiotherapy, neck dissection, tracheostomy) factors favoring postoperative complications. Sixteen days after surgery, he developed a painful swelling with overlying erythematous skin at the level of the medial portion of the left clavicle. A purulent discharge from the adjacent stomal dehiscence was also noted. COM, suspected on the base of patient's history and clavicular inspection, was confirmed by CT scan. Surgical debridement allowed for definitive diagnosis, ruling out any possible suspicion of stomal recurrence or secondary localization to the clavicle. Cultures from the debrided bone sequestra grew Streptococcus pyogenes Group A and allowed for proper targeting of antibiotic therapy, which was carried out for 4 weeks after surgery. Four years after surgery the patient is tumor-free and does not show any sequela related to the COM or its treatment. COM is a rarely encountered complication after major head and neck surgery. Nevertheless, prompt diagnosis and treatment are mandatory due to the potential life-threatening evolution of this condition. PMID:16612610

The integrated evaluation of the results of oncoplastic surgery for locally advanced breast cancer.  

PubMed

The optimal surgical management of locally advanced breast cancer (LABC) remains undefined. The aim of the study was to obtain long-term results of oncoplastic surgery in terms of overall survival, loco-regional recurrence, and quality of life in case of LABC. Prospective cohort study enrolled 60 patients with stage III breast cancer. Forty-two (70%) patients received neo-adjuvant chemotherapy, 28 patients were considered suitable for surgery as initial treatment option. Type II oncoplastic surgery was performed for all patients: hemimastectomy and breast reconstruction with latissimus dorsi flap - for 29 (48.3%), lumpectomy - 31 (51.7%), and reconstruction with subaxillary flap for four (6.7%), with bilateral reduction mammoplasty - 14 (23.3%) and with J-plastic - 13 (21.7%) patients. Adjuvant chemotherapy and hormonal therapy followed surgery for all, except one, patients. Sequential radiotherapy was administered for all patients. The mean period of follow-up was 86 months. Postoperative morbidity rate was 5%. Local-regional recurrence was detected in six (10%) patients. After reoperation no local relapse was diagnosed. However, three of these patients had systemic dissemination of the disease. Distant metastasis was detected in 23 (38.3%) patients. Distant metastasis-free survival at 5 years was 61.7%. Fourteen patients died (23.3%). A total of 87.2% of the patients had good and excellent esthetic outcome. Oncoplastic breast-conserving surgery can be proposed for selected patients with LABC with acceptable complication, local recurrence rate, and good esthetic results. PMID:24237716

Case management vocational rehabilitation for women with breast cancer after surgery: a feasibility study incorporating a pilot randomised controlled trial  

PubMed Central

Background There is a paucity of methodologically robust vocational rehabilitation (VR) intervention trials. This study assessed the feasibility and acceptability of a VR trial of women with breast cancer to inform the development of a larger interventional study. Methods Women were recruited in Scotland and randomised to either a case management VR service or to usual care. Data were collected on eligibility, recruitment and attrition rates to assess trial feasibility, and interviews conducted to determine trial acceptability. Sick leave days (primary outcome) were self-reported via postal questionnaire every 4 weeks during the first 6 months post-surgery and at 12 months. Secondary outcome measures were change in employment pattern, quality of life and fatigue. Results Of the 1,114 women assessed for eligibility, 163 (15%) were eligible. The main reason for ineligibility was age (>65 years, n = 637, 67%). Of those eligible, 111 (68%) received study information, of which 23 (21%) consented to participate in the study. Data for 18 (78%) women were analysed (intervention: n = 7; control: n = 11). Participants in the intervention group reported, on average, 53 fewer days of sick leave over the first 6 months post-surgery than those in the control group; however, this difference was not statistically significant (p = 0.122; 95% confidence interval ?15.8, 122.0). No statistically significant differences were found for secondary outcomes. Interviews with trial participants indicated that trial procedures, including recruitment, randomisation and research instruments, were acceptable. Conclusions Conducting a pragmatic trial of effectiveness of a VR intervention among cancer survivors is both feasible and acceptable, but more research about the exact components of a VR intervention and choice of outcomes to measure effectiveness is required. VR to assist breast cancer patients in the return to work process is an important component of cancer survivorship plans. Trial registration ISRCTN29666484 PMID:23768153

Case-Matched comparison of contemporary radiation therapy to surgery in patients with locally advanced prostate cancer  

SciTech Connect

Purpose: Few studies critically compare current radiotherapy techniques to surgery for patients with locally advanced prostate cancer, despite an urgent need to determine which approach offers superior cancer control. Our objective was to compare rates of biochemical relapse-free survival (BFS) and surrogates of disease specific survival among men with high risk adenocarcinoma of the prostate as a function of treatment modality. Methods and Materials: Retrospective data from 409 men with prostate-specific antigen (PSA) {>=}10 or Gleason 7-10 or Stage {>=}T2b cancer treated uniformly at one university between March 1988 and December 2000 were analyzed. Patients had undergone radical prostatectomy (RP), brachytherapy implant alone (BTM), or external beam radiotherapy with brachytherapy boost with short-term neoadjuvant and adjuvant androgen deprivation therapy (BTC). From the total study population a 1:1 matched-cohort analysis (208 patients matched via prostate-specific antigen, Gleason score) comparing RP with BTC was performed as well. Results: Estimated 4-year BFS rates were superior for patients treated with BTC (BTC 72%, BTM 25%, RP 53%; p < 0.001). Matched analysis of BTC vs. RP confirmed these results (BTC 73%, BTM 55%; p = 0.010). Relative risk (RR) of biochemical relapse for BTM and BTC compared with RP were 2.92 (1.95-4.36) and 0.56 (0.36-0.87) (p < 0.001, p = 0.010). RR for BTC from the matched cohort analysis was 0.44 (0.26-0.74; p = 0.002). Conclusions: High-risk prostate cancer patients receiving multimodality radiation therapy (BTC) display apparently superior BFS compared with those receiving surgery (RP) or brachytherapy alone (BTM)

Video-assisted surgery for lung cancer. State of the art and personal experience.  

PubMed

This paper reviews the role of videothoracoscopy in lung cancer, highlighting its utility in definitive staging, diagnosis, and treatment. We show exploratory videothoracoscopy to be the perfect technique for last-minute staging, looking for tumor invasion, especially parietal T3 and vascular T4 (due to videopericardioscopy), management of solitary pulmonary nodules, and the possibility of radical treatment with video-assisted thoracoscopic lobectomy. We perform an overview of the literature and analyze our experience of 1,381 patients with lung cancer. In 1,277 of them, the final decision on resectability was made by exploratory videothoracoscopy, including 91 by videopericardioscopy (only 30 were considered non-resectable on videopericardioscopy). Solitary pulmonary nodules were diagnosed in 382 cases (190 were cancer), and we performed 260 major lung resections by video-assisted thoracoscopic surgery (22 pneumonectomies, 238 lobectomies/bilobectomies).

Is Early Enteral Nutrition Initiated Within 24 Hours Better for the Postoperative Course in Esophageal Cancer Surgery?  

PubMed Central

Background Early enteral nutrition within 24 h after surgery has become a recommended procedure. In the present study, we retrospectively examined whether initiating EN within 24 h after esophagectomy improves the postoperative course. Methods Among 103 patients who underwent thoracic esophagectomy for esophageal cancer, we enrolled the cases in which EN was initiated within 72 h after surgery. The patients were divided into two groups: EN started within 24 h (Group D1) and EN started at 24 - 72 h (Group D2-3). Clinical factors including days for first fecal passage, dose of postoperative albumin infusion, difference in serum albumin between pre- and postoperation, incidence of postoperative infection, and use of total parenteral nutrition were compared. Statistical analyses were performed by the Mann-Whitney U test and Chi square test, with significance defined as P < 0.05. Results There was no significant difference between the groups in clinical factors. While pneumonia was significantly more frequent in Group D1 than in Group D2-3 (P = 0.0308), the frequency of infectious complications was comparable between the groups. Conclusion Initiating EN within 24 h showed no advantage for the postoperative course in esophageal cancer, and thus EN should be scheduled within 24 - 72 h, based on the patient condition.

The influence of goal-directed fluid therapy on the prognosis of elderly patients with hypertension and gastric cancer surgery  

PubMed Central

Purpose We aimed to investigate the influence of perioperative goal-directed fluid therapy (GDFT) on the prognosis of elderly patients with gastric cancer and hypertension. Methods Sixty elderly patients (>60 years old) with primary hypertension who received gastric cancer radical surgery and who were American Society of Anesthesiologists (ASA) class II or III were enrolled in the current study. Selected patients were divided randomly into two arms, comprising a conventional intraoperative fluid management arm (arm C, n=30) and a GDFT arm (arm G, n=30). Patients in arm C were infused with crystalloids or colloids according to the methods of Miller’s Anesthesia (6th edition), while those in arm G were infused with 200 mL hydroxyethyl starch over 15 minutes under the FloTrac/Vigileo monitoring system, with stroke volume variation between 8% and 13%. Hemodynamics and tissue perfusion laboratory indicators in patients were recorded continuously from 30 minutes before the operation to 24 hours after the operation. Results Compared with arm C, the average intraoperative intravenous infusion quantity in arm G was significantly reduced (2,732±488 mL versus 3,135±346 mL, P<0.05), whereas average colloid fluid volume was significantly increased (1,235±360 mL versus 760±280 mL, P<0.05). In addition, there were more patients exhibiting intraoperatively and postoperatively stable hemodynamics and less patients with low blood pressure in arm G. Postoperative complications were less frequent, and the time of postoperative hospital stay shorter, in arm G. No significant differences were observed in mortality between the two arms. Conclusion Our research showed that GDFT stabilized perioperative hemodynamics and reduced the occurrence of postoperative complications in elderly patients who underwent gastric cancer surgery.

Laparoscopic versus open surgery for rectal cancer: Results of a systematic review and meta-analysis on clinical efficacy  

PubMed Central

Colorectal cancer is one of the main malignant tumors threatening human health. Surgery plays a pivotal role in treating colorectal cancer. The present study aimed to compare the clinical effect in patients with rectal cancer undergoing laparoscopic versus open surgery by meta-analysis of the randomized controlled trials (RCTs) published in the past 20 years. The data showed that 14 RCTs comparing laparoscopic surgery with conventional open surgery for rectal cancer matched the selection criteria and reported on 2,114 subjects, of whom 1,111 underwent laparoscopic surgery and 1,003 underwent open surgery for rectal cancer. Blood loss (P<0.00001), days to passage of flatus (P=0.0003), first bowel movement (P=0.0006), fluids intake (P<0.00001), walking independently (P<0.00001), length of hospital duration (P=0.003) and the rate of wound infection (P=0.04) were all significantly reduced following laparoscopic surgery. The incidence of complications, such as ureteric injury (P=0.33), urinary retention (P=0.43), ileus (P=0.05), anastomotic leakage (P=0.09) and incisional hernia (P=0.88), were not significantly different between the two groups. There were no significant differences in lymph nodes harvested (P=0.88), length of specimen (P=0.60), circumferential resection margin (CRM) (P=0.86), regional recurrence ((P=0.08), port site or wound metastasis (P=0.67), distant metastasis (P=0.12), 3-year overall survival (OS) (P=0.42), 3-year disease-free survival (DFS) (P=0.44), 5-year OS (P=0.60) and 5-year DFS (P=0.70). Therefore, laparoscopy for the treatment of patients with rectal cancer has the advantage of recovery and the same complications and prognosis as laparotomy, which indicates that laparoscopy may provide a potential survival benefit for patients with rectal cancer.

[Modified posterior exenteration (radical oophorectomy type II) as a part of an extensive surgery of ovarian cancer--case report].  

PubMed

Epithelial ovarian cancer remains to be the most deadly gynecologic cancer among the female population. Carcinogenesis and abdomen extension are the reasons why ovarian cancer is still examined in advances stages. Ovarian cancer frequent metastasizes to the uterus, rectosigmoid colon, and other pelvic structures by intraperitoneal seeding of tumor deposits, as well as direct extension. Multiple modalities of therapy are utilized in the management of the disease. Numerous medical trials and research programs have demonstrated the most important role of surgery in the treatment of this disease. A vast majority of authors are of the opinion that the surgical interventions have a major influence on the overall survival (OS) and progression free survival (PFS) in ovarian cancer cases. The paper presents a case of a 35-year-old woman diagnosed with advanced ovarian cancer who underwent modified posterior exenteration as a part of extensive cytoreductive surgery PMID:24032266

Relationship Between Tumor Gene Expression and Recurrence in Four Independent Studies of Patients With Stage II/III Colon Cancer Treated With Surgery Alone or Surgery Plus Adjuvant Fluorouracil Plus Leucovorin  

PubMed Central

Purpose These studies were conducted to determine the relationship between quantitative tumor gene expression and risk of cancer recurrence in patients with stage II or III colon cancer treated with surgery alone or surgery plus fluorouracil (FU) and leucovorin (LV) to develop multigene algorithms to quantify the risk of recurrence as well as the likelihood of differential treatment benefit of FU/LV adjuvant chemotherapy for individual patients. Patients and Methods We performed quantitative reverse transcription polymerase chain reaction (RT-qPCR) on RNA extracted from fixed, paraffin-embedded (FPE) tumor blocks from patients with stage II or III colon cancer who were treated with surgery alone (n = 270 from National Surgical Adjuvant Breast and Bowel Project [NSABP] C-01/C-02 and n = 765 from Cleveland Clinic [CC]) or surgery plus FU/LV (n = 308 from NSABP C-04 and n = 508 from NSABP C-06). Overall, 761 candidate genes were studied in C-01/C-02 and C-04, and a subset of 375 genes was studied in CC/C-06. Results A combined analysis of the four studies identified 48 genes significantly associated with risk of recurrence and 66 genes significantly associated with FU/LV benefit (with four genes in common). Seven recurrence-risk genes, six FU/LV-benefit genes, and five reference genes were selected, and algorithms were developed to identify groups of patients with low, intermediate, and high likelihood of recurrence and benefit from FU/LV. Conclusion RT-qPCR of FPE colon cancer tissue applied to four large independent populations has been used to develop multigene algorithms for estimating recurrence risk and benefit from FU/LV. These algorithms are being independently validated, and their clinical utility is being evaluated in the Quick and Simple and Reliable (QUASAR) study. PMID:20679606

Stereotactic Body Radiotherapy Versus Surgery for Medically Operable Stage I Non-Small-Cell Lung Cancer: A Markov Model-Based Decision Analysis  

SciTech Connect

Purpose: To compare the quality-adjusted life expectancy and overall survival in patients with Stage I non-small-cell lung cancer (NSCLC) treated with either stereotactic body radiation therapy (SBRT) or surgery. Methods and Materials: We constructed a Markov model to describe health states after either SBRT or lobectomy for Stage I NSCLC for a 5-year time frame. We report various treatment strategy survival outcomes stratified by age, sex, and pack-year history of smoking, and compared these with an external outcome prediction tool (Adjuvant{exclamation_point} Online). Results: Overall survival, cancer-specific survival, and other causes of death as predicted by our model correlated closely with those predicted by the external prediction tool. Overall survival at 5 years as predicted by baseline analysis of our model is in favor of surgery, with a benefit ranging from 2.2% to 3.0% for all cohorts. Mean quality-adjusted life expectancy ranged from 3.28 to 3.78 years after surgery and from 3.35 to 3.87 years for SBRT. The utility threshold for preferring SBRT over surgery was 0.90. Outcomes were sensitive to quality of life, the proportion of local and regional recurrences treated with standard vs. palliative treatments, and the surgery- and SBRT-related mortalities. Conclusions: The role of SBRT in the medically operable patient is yet to be defined. Our model indicates that SBRT may offer comparable overall survival and quality-adjusted life expectancy as compared with surgical resection. Well-powered prospective studies comparing surgery vs. SBRT in early-stage lung cancer are warranted to further investigate the relative survival, quality of life, and cost characteristics of both treatment paradigms.

Desmoid tumor requiring differentiation from port-site relapse after surgery for lung cancer.  

PubMed

Thoracoscopic left lower lobectomy with lymph node dissection for lung cancer was performed in a 76-year-old man. The diagnosis was pT2aN2M0 adenocarcinoma. Sixteen months after surgery, CT revealed a pleural tumor measuring 38?mm at the surgical port wound. CT-guided biopsy revealed fibroma. However, the tumor size increased 4 months after biopsy, and surgery was performed. An intraoperative diagnosis revealed benign fibroma. Thoracoscopic tumorectomy was conducted. The pathological diagnosis was desmoid tumor. As the margins of the resected specimen were positive, radiotherapy was performed. During the 16-month follow-up period, there has been no relapse. Pleural desmoid tumors must be differentiated from port-site relapse. PMID:24754885

How does preoperative radiotherapy affect the rate of sphincter-sparing surgery in rectal cancer?  

PubMed

The use of preoperative radiotherapy has resulted in significant downstaging and downsizing of tumor, this in turn facilitated resections permitting sphincter preservation and coloanal anastomosis for patients who would otherwise have not been candidates for this type of surgery as concluded by some small studies. On the other hand, other clinical trials have shown that the effect of radiotherapy on the rate of sphincter preservation is still not clear. Moreover, different modes of radiotherapy have been tested on the rate of sphincter preservation such as pelvic irradiation with or without combination of chemotherapy, short or conventional course radiotherapy, and preoperative or postoperative radiotherapy with different timing intervals of surgery. Unfortunately, these trials didn't clearly answer the question of radiotherapy benefit for the sake of sphincter preserving of rectal cancer patients and the question remained hotly debated.

Efficacy of Physiotherapy for Urinary Incontinence following Prostate Cancer Surgery  

PubMed Central

The study enrolled 81 with urinary incontinence following radical prostate-only prostatectomy for prostatic carcinoma. The patients were divided into two groups. The patients in Group I were additionally subdivided into two subgroups with respect to the physiotherapeutic method used. The patients of subgroup IA received a rehabilitation program consisting of three parts. The patients of subgroup IB rehabilitation program consist of two parts. Group II, a control group, had reported for therapy for persistent urinary incontinence following radical prostatectomy but had not entered therapy for personal reasons. For estimating the level of incontinence, a 1-hour and 24-hour urinary pad tests, the miction diary, and incontinence questionnaire were used, and for recording the measurements of pelvic floor muscles tension, the sEMG (surface electromyography) was applied. The therapy duration depended on the level of incontinence and it continued for not longer than 12 months. Superior continence outcomes were obtained in Group I versus Group II and the difference was statistically significant. The odds ratio for regaining continence was greater in the rehabilitated Group I and smaller in the group II without the rehabilitation. A comparison of continence outcomes revealed a statistically significant difference between Subgroups IA versus IB. The physiotherapeutic procedures applied on patients with urine incontinence after prostatectomy, for most of them, proved to be an effective way of acting, which is supported by the obtained results.

Is community treatment best? a randomised trial comparing delivery of cancer treatment in the hospital, home and GP surgery  

PubMed Central

Background: Care closer to home is being explored as a means of improving patient experience as well as efficiency in terms of cost savings. Evidence that community cancer services improve care quality and/or generate cost savings is currently limited. A randomised study was undertaken to compare delivery of cancer treatment in the hospital with two different community settings. Methods: Ninety-seven patients being offered outpatient-based cancer treatment were randomised to treatment delivered in a hospital day unit, at the patient's home or in local general practice (GP) surgeries. The primary outcome was patient-perceived benefits, using the emotional function domain of the EORTC quality of life (QOL) QLQC30 questionnaire evaluated after 12 weeks. Secondary outcomes included additional QOL measures, patient satisfaction, safety and health economics. Results: There was no statistically significant QOL difference between treatment in the combined community locations relative to hospital (difference of ?7.2, 95% confidence interval: ?19·5 to +5·2, P=0.25). There was a significant difference between the two community locations in favour of home (+15·2, 1·3 to 29·1, P=0.033). Hospital anxiety and depression scale scores were consistent with the primary outcome measure. There was no evidence that community treatment compromised patient safety and no significant difference between treatment arms in terms of overall costs or Quality Adjusted Life Year. Seventy-eight percent of patients expressed satisfaction with their treatment whatever their location, whereas 57% of patients preferred future treatment to continue at the hospital, 81% at GP surgeries and 90% at home. Although initial pre-trial interviews revealed concerns among health-care professionals and some patients regarding community treatment, opinions were largely more favourable in post-trial interviews. Interpretation: Patient QOL favours delivering cancer treatment in the home rather than GP surgeries. Nevertheless, both community settings were acceptable to and preferred by patients compared with hospital, were safe, with no detrimental impact on overall health-care costs. PMID:23989945

Single-incision laparoscopic colorectal surgery for cancer: State of art  

PubMed Central

A number of clinical trials have demonstrated that the laparoscopic approach for colorectal cancer resection provides the same oncologic results as open surgery along with all clinical benefits of minimally invasive surgery. During the last years, a great effort has been made to research for minimizing parietal trauma, yet for cosmetic reasons and in order to further reduce surgery-related pain and morbidity. New techniques, such as natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopy (SIL) have been developed in order to reach the goal of “scarless” surgery. Although NOTES may seem not fully suitable or safe for advanced procedures, such as colectomies, SIL is currently regarded as the next major advance in the progress of minimally invasive surgical approaches to colorectal disease that is more feasible in generalized use. The small incision through the umbilicus allows surgeons to use familiar standard laparoscopic instruments and thus, perform even complex procedures which require extraction of large surgical specimens or intestinal anastomosis. The cosmetic result from SIL is also better because the only incision is made through the umbilicus which can hide the wound effectively after operation. However, SIL raises a number of specific new challenges compared with the laparoscopic conventional approach. A reduced capacity for triangulation, the repeated conflicts between the shafts of the instruments and the difficulties to achieve a correct exposure of the operative field are the most claimed issues. The use therefore of this new approach for complex colorectal procedures might understandingly be viewed as difficult to implement, especially for oncologic cases. PMID:24876729

Factors Associated With Decisions to Undergo Surgery Among Patients With Newly Diagnosed Early-Stage Lung Cancer  

PubMed Central

Context Lung cancer is the leading cause of cancer death in the United States. Surgical resection for stage I or II non–small cell cancer remains the only reliable treatment for cure. Patients who do not undergo surgery have a median survival of less than 1 year. Despite the survival disadvantage, many patients with early-stage disease do not receive surgical care and rates are even lower for black patients. Objectives To identify potentially modifiable factors regarding surgery in patients newly diagnosed with early-stage lung cancer and to explore why blacks undergo surgery less often than whites. Design, Setting, and Patients Prospective cohort study with patients identified by pulmonary, oncology, thoracic surgery, and generalist practices in 5 communities through study referral or computerized tomography review protocol. A total of 437 patients with biopsy-proven or probable early-stage lung cancer were enrolled between December 2005 and December 2008. Before establishment of treatment plans, patients were administered a survey including questions about trust, patient-physician communication, attitudes toward cancer, and functional status. Information about comorbid illnesses was obtained through chart audits. Main Outcome Measure Lung cancer surgery within 4 months of diagnosis. Results A total of 386 patients met full eligibility criteria for lung resection surgery. The median age was 66 years (range, 26–90 years) and 29% of patients were black. The surgical rate was 66% for white patients (n=179/273) compared with 55% for black patients (n=62/113; P=.05). Negative perceptions of patient-physician communication manifested by a 5-point decrement on a 25-point communication scale (odds ratio [OR], 0.42; 95% confidence interval [CI], 0.32–0.74) and negative perception of 1-year prognosis postsurgery (OR, 0.27; 95% CI, 0.14–0.50; absolute risk, 34%) were associated with decisions against surgery. Surgical rates for blacks were particularly low when they had 2 or more comorbid illnesses (13% vs 62% for <2 comorbidities; OR, 0.04 [95% CI, 0.01–0.25]; absolute risk, 49%) and when blacks lacked a regular source of care (42% with no regular care vs 57% with regular care; OR, 0.20 [95% CI, 0.10–0.43]; absolute risk, 15%). Conclusions A decision not to undergo surgery by patients with newly diagnosed lung cancer was independently associated with perceptions of communication and prognosis, older age, multiple comorbidities, and black race. Interventions to optimize surgery should consider these factors. PMID:20551407

One hundred and forty-four dogs with untreated malignant mammary tumors (136 adenocarcinomas, 5 malignant mixed, 3 sarcomas) were selected for study. All dogs were clinically staged and stratified on the basis of tumor volume and body weight. Dogs were randomized to either a radical mastectomy or simple mastectomy group, and then further randomized to a levamisole or placebo group. There was no significant difference in either survival time or cancer-free survival time between the surgery groups or between the levamisole and placebo groups. The most significant prognostic factor was tumor volume; dogs with tumors less than 41 cc had significantly enhanced survival time (p = 0.0007) and cancer-free survival time (p = 0.0005).

Effect of articulatory rehabilitation after oral cancer surgery on higher brain activation.  

PubMed

The present study aimed to verify the importance of postoperative articulatory rehabilitation in patients with oral cancer and to clarify the neurological changes underlying articulatory functional recovery. A longitudinal assessment of oral function and accompanying brain activity was performed using non-invasive functional magnetic resonance imaging (fMRI). We assessed 13 patients with cancers of the tongue and oral floor before and after ablative surgery. Articulatory function was assessed preoperatively and postoperatively using a conversation intelligibility test and the Assessment of Motor Speech for Dysarthria test. Patients also performed a verbal task during fMRI scans. The assessments were then repeated after the patients had undergone 4-6 months of articulatory rehabilitation therapy. Compared to pretreatment levels, articulatory rehabilitation resulted in a significant increase in activation in the supplementary motor cortex, thalamus, and cingulate cortex. The present study offers a quantitative assessment of the effects of speech rehabilitation by investigating changes in brain activation sites. PMID:24679850

Cosmetic Outcome and Seroma Formation After Breast-Conserving Surgery With Intraoperative Radiation Therapy Boost for Early Breast Cancer  

SciTech Connect

Purpose: To evaluate cosmetic outcome and its association with breast wound seroma after breast-conserving surgery (BCS) with targeted intraoperative radiation therapy (tIORT) boost for early breast cancer. Methods and Materials: An analysis of a single-arm prospective study of 55 patients with early breast cancer treated with BCS and tIORT boost followed by conventional whole breast radiation therapy (WBRT) between August 2003 and January 2006 was performed. A seroma was defined as a fluid collection at the primary tumor resection site identified clinically or radiologically. Cosmetic assessments using the European Organization for Research and Treatment of Cancer rating system were performed at baseline before BCS and 30 months after WBRT was completed. Results: Twenty-eight patients (51%) developed a seroma, with 18 patients (33%) requiring at least 1 aspiration. Tumor location was significantly associated with seroma formation (P=.001). Ten of 11 patients with an upper inner quadrant tumor developed a seroma. Excellent or good overall cosmetic outcome at 30 months was observed in 34 patients (62%, 95% confidence interval 53%-80%). Seroma formation was not associated with the overall cosmetic result (P=.54). Conclusion: BCS with tIORT boost followed by WBRT was associated with an acceptable cosmetic outcome. Seroma formation was not significantly associated with an adverse cosmetic outcome.

Drug-eluting scaffold to deliver chemotherapeutic medication for management of pancreatic cancer after surgery  

PubMed Central

Traditional post-surgical chemotherapy for pancreatic cancer is notorious for its devastating side effects due to the high dosage required. On the other hand, legitimate concerns have been raised about nanoparticle-mediated drug delivery because of its potential cytotoxicity. Therefore, we explored the local delivery of a reduced dosage of FOLFIRINOX, a four-drug regimen comprising oxaliplatin, leucovorin, irinotecan, and fluorouracil, for pancreatic cancer using a biocompatible drug-eluting scaffold as a novel chemotherapy strategy after palliative surgery. In vitro assays showed that FOLFIRINOX in the scaffold caused massive apoptosis and thereby a decrease in the viability of pancreatic cancer cells, confirming the chemotherapeutic capability of the drug-eluting scaffold. In vivo studies in an orthotopic murine xenograft model demonstrated that the FOLFIRINOX in the scaffold had antitumorigenic and antimetastatic effects comparable with those achieved by intraperitoneal injection, despite the dose released by the scaffold being roughly two thirds lower. A mechanistic study attributed our results to the excellent ability of the FOLFIRINOX in the scaffold to destroy the CD133+CXCR4+ cell population responsible for pancreatic tumorigenesis and metastasis. This clinically oriented study gives rise to a promising alternative strategy for postsurgical management of pancreatic cancer, featuring a local chemotherapeutic effect with considerable attenuation of side effects.

Comparison of hormonal receptor and HER2 status between ultrasound-guided 14-gauge core needle biopsy and surgery in breast cancer patients  

PubMed Central

Purpose: To evaluate the concordance of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 (HER2) statuses between ultrasound (US)-guided 14-gauge core needle biopsy (CNB) and surgery and to analyze whether the clinicopathological and imaging features including those from mammography and ultrasonography can predict the concordance in breast cancer patients. Methods: The concordance of receptor status between CNB and surgery was assessed for 55 breast cancers in 55 women who underwent CNB before treatment. The clinicopathological and imaging features and the concordance rates were compared between the non-neoadjuvant chemotherapy (non-NAC) group and the NAC group according to the initial treatment. The concordance rates were analyzed according to the clinicopathological and imaging features, by using the chi-square or Fisher exact test and McNemar test for the categorical and the independent t-test for continuous variables. Results: Among 55 women, 22 women (40%) were part of the non-NAC group and 33 women (60%) were part of the NAC group. The concordance rates were 0.86-1.00 in the non-NAC group and 0.76-0.88 in the NAC group. In all three receptors, the difference in the concordance rate between the two groups was not significant. In the NAC group, the absence of axillary lymph node metastasis (1.00, P=0.02) and visibility of cancer on mammography (0.93, P=0.04) showed the higher concordance of the HER2 status. Conclusion: Concordance of the receptor status between surgery and US-guided 14-gauge CNB was feasible in breast cancer patients. The absence of axillary lymph node metastasis after NAC and the visibility of cancer on mammography prior to NAC may be helpful for predicting the concordance of HER2 in breast cancer patients.

Effects of magnesium sulphate on coagulation after laparoscopic colorectal cancer surgery, measured by rotational thromboelastometry (ROTEM(®) ).  

PubMed

We investigated the effects of magnesium sulphate on blood coagulation profiles using rotational thromboelastometry in patients undergoing laparoscopic colorectal cancer surgery. Patients were randomly allocated to the magnesium group (n = 22) or control group (n = 22). The magnesium group received intravenous magnesium sulphate (50 mg.kg(-1) followed by a continuous infusion of 15 mg.kg(-1) .h(-1) ), whereas the control group received the same volume of isotonic saline. Mean (SD) postoperative serum magnesium levels were 1.60 (0.13) mmol.l(-1) in the magnesium group compared with 0.98 (0.06) mmol.l(-1) in the control group (p < 0.001). All maximum clot firmness values of ROTEM analysis were significantly lower on the third postoperative day in the magnesium group compared with the control group (p < 0.05). We conclude that ROTEM analysis demonstrated that intra-operative administration of intravenous magnesium sulphate reduces blood hypercoagulability in patients undergoing laparoscopic colorectal cancer surgery.

Fertility Preservation Methods in Breast Cancer  

PubMed Central

Thanks to the recent advances in reproductive medicine, more and more young women with breast cancer may be offered the possibility of preserving their fertility. Fertility can be endangered by chemotherapy, by treatment duration and by patient's age at diagnosis. The currently available means to preserve a young woman's fertility are pharmacological protection with gonadotrophin-releasing hormone analogues during chemotherapy, and ovarian tissue or oocyte/embryo freezing before treatment. New future venues, including in vitro maturation, will improve the feasibility and efficacy of the fertility preservation methods in breast cancer patients. PMID:22872792

Thoracoscopic minimally invasive surgery for non-small cell lung cancer in patients with chronic obstructive pulmonary disease  

PubMed Central

Objective To determine the incidence of peri-operative complications in non-small cell lung cancer (NSCLC) patients with co-existent chronic obstructive pulmonary disease (COPD) who undergo lung resection via traditional and minimally invasive techniques. Methods A retrospective analysis was conducted of 152 NSCLC patients with COPD who underwent thoracoscopic minimally invasive surgery. Particular attention is given to the relationship between disease severity or surgical approach and the incidence of complications. Results The prevalence of respiratory and cardiac complications was significantly higher in patients with severe/extremely severe COPD than those with mild to moderate COPD (respiratory compications: 37.3% vs. 20.4%, P=0.022; cardiac complications: 16.9% vs. 6.5%, P=0.040). Patients who underwent complete-video assisted thoracoscopic surgery (c-VATS) had a significantly lower overall morbidity of adverse reactions than those who had undergone VATS major resection (26.3% vs. 42.1%, P=0.044). Among patients with severe/extremely severe COPD, there was no significant difference in the incidence of any complication between the lobectomy group and wedge resection group (38.8% vs. 70.0%, P=0.072). Overall, the occurrence of adverse reactions was significantly lower in patients who underwent c-VATS than in those who had undergone VATS major resection surgery (34.2% vs. 61.9%, P=0.038). Conclusions VATS techniques are suitable for COPD patients and are demonstrated here to lower the incidence of post-operative complications when compared with more invasive approaches. PMID:24040534

Determining Which Patients Require Irradiation of the Supraclavicular Nodal Area After Surgery for N1 Breast Cancer  

SciTech Connect

Purpose: We designed this study to determine which patients have a high risk of supraclavicular node recurrence in N1 breast cancer previously treated with surgery but not having received supraclavicular radiation therapy (SCRT) and to identify which patients needed SCRT. Methods and Materials: We performed a retrospective review of 448 pathologic N1 breast cancer patients treated with mastectomy or breast-conserving treatment, but without SCRT, between 1994 and 2003. Mastectomy was performed in 302 patients (67.4%). The median number of axillary nodes dissected was 17 (range, 5-53). Systemic chemotherapy was administered in 443 patients (98.9%), and 144 patients received radiation after breast-conserving surgery. The median follow-up was 88 months (range, 15-170 months). Results: At follow-up, the treatment failed in 101 patients (22.5%), and 39 patients (8.7%) had supraclavicular node recurrence. Prognostic factors in supraclavicular node recurrence included lymphovascular invasion (p < 0.0001), extracapsular extension (p < 0.0001), the number of involved axillary nodes (p = 0.0003), and the level of involved axillary nodes (p = 0.012) in univariate and multivariate analyses. The total number of prognostic factors correlated well with supraclavicular node recurrence. In the analysis of 5-year supraclavicular node recurrence-free survival, patients with two or more factors showed a significantly higher recurrence rate than did patients with fewer than two factors (96.8% and 72.9%, respectively; p < 0.0001). Conclusions: The prognostic factors associated with supraclavicular node recurrence were lymphovascular invasion, extracapsular extension, and the number and level of involved axillary nodes. Patients with two or more prognostic factors might benefit from SCRT.

Integration of robotics into two established programs of minimally invasive surgery for endometrial cancer appears to decrease surgical complications  

PubMed Central

Objective To compare peri- and postoperative outcomes and complications of laparoscopic vs. robotic-assisted surgical staging for women with endometrial cancer at two established academic institutions. Methods Retrospective chart review of all women that underwent total hysterectomy with pelvic and para-aortic lymphadenectomy by robotic-assisted or laparoscopic approach over a four-year period by three surgeons at two academic institutions. Intraoperative and postoperative complications were measured. Secondary outcomes included operative time, blood loss, transfusion rate, number of lymph nodes retrieved, length of hospital stay and need for re-operation or re-admission. Results Four hundred and thirty-two cases were identified: 187 patients with robotic-assisted and 245 with laparoscopic staging. Both groups were statistically comparable in baseline characteristics. The overall rate of intraoperative complications was similar in both groups (1.6% vs. 2.9%, p=0.525) but the rate of urinary tract injuries was statistically higher in the laparoscopic group (2.9% vs. 0%, p=0.020). Patients in the robotic group had shorter hospital stay (1.96 days vs. 2.45 days, p=0.016) but an average 57 minutes longer surgery than the laparoscopic group (218 vs. 161 minutes, p=0.0001). There was less conversion rate (0.5% vs. 4.1%; relative risk, 0.21; 95% confidence interval, 0.03 to 1.34; p=0.027) and estimated blood loss in the robotic than in the laparoscopic group (187 mL vs. 110 mL, p=0.0001). There were no significant differences in blood transfusion rate, number of lymph nodes retrieved, re-operation or re-admission between the two groups. Conclusion Robotic-assisted surgery is an acceptable alternative to laparoscopy for staging of endometrial cancer and, in selected patients, it appears to have lower risk of urinary tract injury.

Biological Effects of Green Tea Capsule Supplementation in Pre-Surgery Postmenopausal Breast Cancer Patients  

PubMed Central

Regular green tea intake has been associated with an inverse risk of breast cancer. There are compelling experimental evidence that green tea, particularly, epigallocatechin gallate, the most potent green tea catechin, possesses a range of anti-cancer properties. We conducted a pre-surgical study of green tea capsules vs. no-green tea in women with primary breast cancer to determine the effects of green tea supplementation on markers of biological response. Postmenopausal women with ductal carcinoma in situ (DCIS) or stage I or II breast cancer took green tea capsules (940?mg per day) for an average of 35?days prior to surgery (n?=?13) or received no green tea (n?=?18). Paired diagnostic core biopsy and surgical specimen samples were analyzed for cell proliferation (Ki-67), apoptosis (caspase-3), and angiogenesis (CD34) separately in benign and malignant cell components. There were no significant changes in caspase-3 and CD34 in the green tea and no green tea groups and there were no significant differences in the change in these markers between the two groups. However, Ki-67 levels declined in both benign and malignant cell components in the green tea group; the decline in Ki-67 positivity in malignant cells was not statistically significant (P?=?0.10) but was statistically significant in benign cells (P?=?0.007). Ki-67 levels in benign and malignant cells did not change significantly in the no green tea group. There was a statistically significant difference in the change in Ki-67 in benign cells (P?=?0.033) between the green tea and the no green tea groups. The trend of a consistent reduction in Ki-67 in both benign and malignant cells in the green tea group warrants further investigations in a larger study of breast cancer patients or high-risk women.

Postoperative bladder and sexual function in patients undergoing surgery for rectal cancer: a systematic review and meta-analysis of laparoscopic versus open resection of rectal cancer.  

PubMed

There have been conflicting opinions regarding the superiority of open and laparoscopic surgery in preserving bladder and sexual function after rectal cancer surgery. This systematic review and meta-analysis aims to pool the available data comparing the impact of surgical approaches on postoperative sexual and urinary function. A search of Pubmed, Medline, Cochrane and Embase was undertaken and studies from January 2000 to February 2013 were identified. We included, in our meta-analysis, both prospective and retrospective studies that compared laparoscopic surgery and open surgery for rectal cancer. A total of 876 patients undergoing rectal cancer surgery (lap n = 468, open n = 408) were examined. In men, postoperative ejaculatory function and erectile dysfunction evaluated from two studies comprising of 74 patients showed no difference between groups. The rate of overall sexual dysfunction evaluated from five studies comprising of 289 patients revealed a rate of 34 % in both the open and lap groups. Postoperative urinary function evaluated from five studies comprising of 312 patients showed no difference between groups. In women, postoperative sexual and urinary function were evaluated from five studies comprising of 321 patients. Three studies (n = 219) reported no difference in sexual function between groups. Postoperative urinary function evaluated from four studies comprising of 212 patients was found to be comparable. The available data are limited, but suggest that neither form of surgical approach be it laparoscopy or open surgery demonstrate superiority in preservation of sexual and bladder function. Further research into the technical aspects of surgery and evaluating newer minimally invasive technologies such as the robot may prove to be useful in improving functional outcomes of rectal cancer patients.

Development and feasibility of a set of quality indicators relative to the timeliness and organisation of care for new breast cancer patients undergoing surgery  

PubMed Central

Background Because breast cancer is a major public health issue, it is particularly important to measure the quality of the care provided to patients. Survival rates are affected by the timeliness of care, and waiting times constitute key quality criteria. The aim of this study was to develop and validate a set of quality indicators (QIs) relative to the timeliness and organisation of care in new patients with infiltrating, non-inflammatory and metastasis-free breast cancer undergoing surgery. The ultimate aim was to use these QIs to compare hospitals. Methods The method of QI construction and testing was developed by COMPAQ-HPST. We first derived a set of 8 QIs from consensus guidelines with the aid of experts and professional associations and then tested their metrological properties in a panel of 60 volunteer hospitals. We assessed feasibility using a grid exploring 5 dimensions, discriminatory power using the Gini coefficient as a measure of dispersion, and inter-observer reliability using the Kappa coefficient. Results Overall, 3728 records were included in the analyses. All 8 QIs showed acceptable feasibility (but one QI was subject to misinterpretation), fairly strong agreement between observers (Kappa?=?0.66), and wide variations in implementation among hospitals (Gini coefficient?surgery, time to postoperative multidisciplinary team meeting (MDTM), conformity of MDTM). Four are suitable for use only in hospitals offering surgery with on-site postoperative treatment (waiting time to first appointment after surgery, patient information, time to first postoperative treatment, and traceability of information relating to prognosis). Currently, in the French healthcare system, a patient receives cancer care from different institutions whose databases cannot as yet be easily merged. Nationwide implementation of QIs covering the entire care pathway will thus be a challenge. PMID:22721001

Breast edema in breast cancer patients following breast-conserving surgery and radiotherapy: a systematic review.  

PubMed

Breast-conserving surgery (BCS) is commonly used in breast cancer treatment. Despite its benefits, some women will be troubled by breast edema. Breast edema may cause an unsatisfactory cosmetic result, influencing the quality of life. The purpose of this systematic review is to investigate the incidence of breast edema and to identify risk factors of breast edema in breast cancer patients following BCS and radiotherapy. A systematic literature search was performed using different electronic databases (PubMed, Web of Science, Cochrane, Embase) until June 2014. Inclusion criteria were as follows: (1) research studies that included female breast cancer patients who were treated with BCS and radiotherapy and (2) studies that investigated the incidence of breast edema and/or risk factors of breast edema. Exclusion criteria were (1) reviews or case studies and (2) studies published before 1995. We identified in total 28 papers which represented 4,011 patients. There was a great variation in the incidence of breast edema (0-90.4 %). We identified several possible risk factors for breast edema namely increasing irradiated breast volume, increasing boost volume, the use of a photon boost, increasing breast separation, a higher density of the breast tissue, a large tumor, a higher specimen weight, postoperative infection, acute postoperative toxicity, and diabetes mellitus. However, their prognostic value remains uncertain. Breast edema is a common complaint after BCS and radiotherapy. A number of possible risk factors associated with breast edema were identified, but further research is warranted. PMID:25164973

Breast cancer in the lower jaw after reconstructive surgery with a pectoralis major myocutaneous flap (PMMC) - A case report  

PubMed Central

For head and neck as well as for oromaxillofacial surgery, the use of the pectoralis major myocutaneous (PMMC) flap is a standard reconstructive technique after radical surgery for cancers in this region. We report to our knowledge for the first development of breast cancer in the PMMC flap in a 79 year old patient, who had undergone several operations in the past for recurring squamous cell carcinoma of the jaw. The occurrence of a secondary malignancy within the donor tissue after flap transfer is rare, but especially in the case of transferred breast tissue and the currently high incidence of breast cancer theoretically possible. Therefore preoperative screening mammography seems advisable to exclude a preexisting breast cancer in female patients undergoing such reconstruction surgery. Therapy for breast cancer under these circumstances is individual and consists of radical tumor resection followed by radiation if applicable and a standard systemic therapeutic regimen on the background of the patients individual prognosis due to the primary cancer.

[Two patients having recurrent breast cancer with brain metastases well controlled with a gamma knife radio-surgery].  

PubMed

We report two patients having recurrent breast cancer with brain metastases that was controlled well with a gamma knife radio-surgery. The patient is a 50-year-old woman. She underwent radical mastectomy for right breast cancer in September 1993. She suffered from multiple liver metastases in June 2000, so CEF therapy contained hepatic arterial infusion chemotherapy, and extended right lobectomy of the liver were performed in December 2001. Afterward, pleurodesis was carried out to the carcinomatous pleurisy. Then she underwent simple total hysterectomy and bilateral oophorectomy for torsion of the metastatic ovarian tumor. MRI study revealed brain metastases with a diameter of 1 cm in her right midbrain in April 2005, so a gamma knife radio-surgery was performed. After the radio-surgery, a weekly paclitaxel therapy followed by peroral chemotherapy with capecitabine was started, and she took the regimen continuously. Another patient is a 56-year-old woman. She underwent skin sparing mastectomy with axillary lymph node dissection for right breast cancer in November 2002. Metastases to the base of her skull were found in October 2004, so a gamma knife radio-surgery was carried out. After the radio-surgery, a weekly paclitaxel therapy with anastrozole was started. In both of the two patients, the metastatic brain tumors have not shown growth so far and are under good control as of March 2006. PMID:17212144

Efficacy of intraoperative, single-bolus corticosteroid administration to prevent postoperative acute respiratory failure after oesophageal cancer surgery  

PubMed Central

OBJECTIVES Respiratory failure from acute lung injury (ALI), acute respiratory distress syndrome (ARDS) and pneumonia are the major cause of morbidity and mortality following an oesophagectomy for oesophageal cancer. This study was performed to investigate whether an intraoperative corticosteroid can attenuate postoperative respiratory failure. METHODS Between November 2005 and December 2008, 234 consecutive patients who underwent an oesophagectomy for oesophageal cancer were reviewed. A 125-mg dose of methylprednisolone was administered after performing the anastomosis. ALI, ARDS and pneumonia occurring before postoperative day (POD) 7 were regarded as acute respiratory failure. RESULT The mean age was 64.2 ± 8.7 years. One hundred and fifty-one patients were in the control group and 83 patients in the steroid group. Patients' characteristics were comparable. The incidence of acute respiratory failure was lower in the steroid group (P = 0.037). The incidences of anastomotic leakage and wound dehiscence were not different (P = 0.57 and P = 1.0). The C-reactive protein level on POD 2 was lower in the steroid group (P < 0.005). Multivariate analysis indicates that the intraoperative steroid was a protective factor against acute respiratory failure (P = 0.046, OR = 0.206). CONCLUSIONS Intraoperative corticosteroid administration was associated with a decreased risk of acute respiratory failure following an oesophagectomy. The laboratory data suggest that corticosteroids may attenuate the stress-induced inflammatory responses after surgery. PMID:22745302

PubMed

Potential use of thermography for more effective detection of breast carcinoma was evaluated on 26 patients scheduled for breast carcinoma surgery. Ultrasonographic scan, mammography and thermography were performed at the University Hospital for Tumors. Thermographic imaging was performed using a new generation of digital thermal cameras with high sensitivity and resolution (ThermoTracer TH7102WL, NEC). Five images for each patient were recorded: front, right semi-oblique, right oblique, left- semi oblique and left oblique. While mammography detected 31 changes in 26 patients, thermography was more sensitive and detected 6 more changes in the same patients. All 37 changes were subjected to the cytological analysis and it was found that 16 of samples were malignant, 8 were suspected malignant and 11 were benign with atypia or proliferation while only 2 samples had benign findings. The pathohistological method (PHD) recorded 75.75% malignant changes within the total number of samples. Statistical analysis of the data has shown a probability of a correct mammographic finding in 85% of the cases (sensitivity of 85%, specificity of 84%) and a probability of a correct thermographic finding in 92% of the cases (sensitivity of 100%, specificity of 79%). As breast cancer remains the most prevalent cancer in women and thermography exhibited superior sensitivity, we believe that thermography should immediately find its place in the screening programs for early detection of breast carcinoma, in order to reduce the sufferings from this devastating disease.

Outcomes of Positron Emission Tomography-Staged Clinical N3 Breast Cancer Treated With Neoadjuvant Chemotherapy, Surgery, and Radiotherapy  

SciTech Connect

Purpose: To evaluate the treatment outcome and efficacy of regional lymph node irradiation after neoadjuvant chemotherapy (NCT) and surgery in positron emission tomography (PET)-positive clinical N3 (cN3) breast cancer patients. Methods and Materials: A total of 55 patients with ipsilateral infraclavicular (ICL), internal mammary (IMN), or supraclavicular (SCL) lymph node involvement in the absence of distant metastases, as revealed by an initial PET scan, were retrospectively analyzed. The clinical nodal stage at diagnosis (2002 AJCC) was cN3a in 14 patients (26%), cN3b in 12 patients (22%), and cN3c in 29 patients (53%). All patients were treated with NCT, followed by mastectomy or breast-conserving surgery and subsequent radiotherapy (RT) with curative intent. Results: At the median follow-up of 38 months (range, 9-80 months), 20 patients (36%) had developed treatment failures, including distant metastases either alone or combined with locoregional recurrences that included one ipsilateral breast recurrence (IBR), six regional failures (RF), and one case of combined IBR and RF. Only 3 patients (5.5%) exhibited treatment failure at the initial PET-positive clinical N3 lymph node. The 5-year locoregional relapse-free survival, disease-free survival (DFS), and overall survival rates were 80%, 60%, and 79%, respectively. RT delivered to PET-positive IMN regions in cN3b patients and at higher doses ({>=}55 Gy) to SCL regions in cN3c patients was not associated with improved 5-year IMN/SCL relapse-free survival or DFS. Conclusion: NCT followed by surgery and RT, including the regional lymph nodes, resulted in excellent locoregional control for patients with PET-positive cN3 breast cancer. The primary treatment failure in this group was due to distant metastasis rather than RF. Neither higher-dose RT directed at PET-positive SCL nodes nor coverage of PET-positive IMN nodes was associated with additional gains in locoregional control or DFS.

Preoperative Short-Course Concurrent Chemoradiation Therapy Followed by Delayed Surgery for Locally Advanced Rectal Cancer: A Phase 2 Multicenter Study (KROG 10-01)  

SciTech Connect

Purpose: A prospective phase 2 multicenter trial was performed to investigate the efficacy and safety of preoperative short-course concurrent chemoradiation therapy (CRT) followed by delayed surgery for patients with locally advanced rectal cancer. Methods and Materials: Seventy-three patients with cT3-4 rectal cancer were enrolled. Radiation therapy of 25 Gy in 5 fractions was delivered over 5 consecutive days using helical tomotherapy. Concurrent chemotherapy was administered on the same 5 days with intravenous bolus injection of 5-fluorouracil (400 mg/m{sup 2}/day) and leucovorin (20 mg/m{sup 2}/day). After 4 to 8 weeks, total mesorectal excision was performed. The primary endpoint was the pathologic downstaging (ypStage 0-I) rate, and secondary endpoints included tumor regression grade, tumor volume reduction rate, and toxicity. Results: Seventy-one patients completed the planned preoperative CRT and surgery. Downstaging occurred in 20 (28.2%) patients, including 1 (1.4%) with a pathologic complete response. Favorable tumor regression (grade 4-3) was observed in 4 (5.6%) patients, and the mean tumor volume reduction rate was 62.5 ± 21.3%. Severe (grade ?3) treatment toxicities were reported in 27 (38%) patients from CRT until 3 months after surgery. Conclusions: Preoperative short-course concurrent CRT followed by delayed surgery for patients with locally advanced rectal cancer demonstrated poor pathologic responses compared with conventional long-course CRT, and it yielded considerable toxicities despite the use of an advanced radiation therapy technique.

A comprehensive multi-institutional study on postoperative adjuvant immunotherapy with oral streptococcal preparation OK-432 for patients after gastric cancer surgery. Kyoto Research Group for Digestive Organ Surgery.  

PubMed Central

The current study was designed to compare the effects of oral administration of the streptococcal preparation, OK-432, as an adjuvant immunotherapy versus those of intradermal administration of OK-432 on the survival of patients after surgery for gastric cancer. The patients were stratified into two groups after surgery: a curative surgery stratum and a palliative surgery stratum. Then the patients in each stratum were randomly assigned into three groups: an oral placebo group, an oral OK-432 group, and an intradermal OK-432 group. All of the patients were given fluoropyrimidines orally in combination with OK-432 or placebo for 2 years after surgery. A total of 1011 patients were registered between 1982 and 1985, and 970 patients were eligible for statistical analysis. The survival rate of the oral OK-432 group was significantly higher than those of the other two groups after curative surgery. There were no significant difference in the survival rates between the three groups after palliative surgery, however. The effect of oral OK-432 was quite pronounced in patients after curative surgery for stage II to IV gastric cancer, especially in those patients with regional node involvement. Furthermore, it was found that the spleen is necessary for effective immunotherapy with oral OK-432, because the survival rate of the oral OK-432 group was significantly improved in patients whose spleens were preserved, when compared with splenectomized patients. These results demonstrate that oral adjuvant immunotherapy with OK-432 is beneficial after curative surgery for gastric cancer. PMID:1632701

A decade in gastric cancer curative surgery: Evidence of progress (1999-2009)  

PubMed Central

To investigate the progress in evidence-based surgical treatment of non-metastatic gastric cancer, we reviewed the last ten years’ literature. The data used in this review were identified by searches made on MEDLINE, Current Contents, PubMed, and other references taken from relevant original articles (on prospective and retrospective studies) concerning gastric cancer surgery. Only papers published in English between January 1999 and December 2009 were selected. Data from ongoing studies were obtained in December 2009, from the trials registry of the United States National Institutes of Health (http://www.clinicaltrial.gov). The citations list was presented according to evidence based relevance (i.e., randomized controlled trials, prospective studies, retrospective series). In the last ten years, many challenges have been faced relating to the extension of gastric resection and nodal dissection as well as surgical timing, but we found only limited evidence, regardless of latitude of study. The ongoing phase-III trials may provide answers that will be valid for the coming decades, and which may bring definitive answers for the currently unresolved questions. PMID:22530078

Digestive cancer surgery in the era of sentinel node and epithelial-mesenchymal transition.  

PubMed

Lymph node involvement is one of the most important prognostic indicators of carcinoma of the digestive tract. Although the therapeutic impact of lymphadenectomy has not been proven and the number of retrieved nodes cannot be considered a measure of successful cancer surgery, an adequate lymph node count should be guaranteed to accurately assess the N-stage through the number of involved nodes, lymph node ratio, number of negative nodes, ratio of negative to positive nodes, and log odds, i.e., the log of the ratio between the number of positive lymph nodes and the number of negative lymph nodes in digestive carcinomas. As lymphadenectomy is not without complications, sentinel node mapping has been used as the rational procedure to select patients with early digestive carcinoma in whom nodal dissection may be omitted or a more limited nodal dissection may be preferred. However, due to anatomical and technical issues, sentinel node mapping and nodal basin dissection are not yet the standard of care in early digestive cancer. Moreover, in light of the biological, prognostic and therapeutic impact of tumor budding and tumor deposits, two epithelial-mesenchymal transition-related phenomena that are involved in tumor progression, the role of staging and surgical procedures in digestive carcinomas could be redefined.

Catalysts to withdrawal from familial ovarian cancer screening for surgery and reactions to discontinued screening: a qualitative study.  

PubMed

Women at high risk of familial ovarian cancer face a potentially difficult risk management choice between unproven ovarian cancer screening (OCS) and bilateral salpingo-oophorectomy (BSO). It is not fully understood why women who initially opt for OCS may later undergo BSO, nor what the impact of this may be. This study explored the catalysts for surgery and reactions to discontinuing OCS. Semi-structured interviews were completed with 21 women who had undergone surgery having initially chosen OCS to explore their screening experiences, reasons for and feelings about surgery, and reactions to discontinuing OCS. The invasive nature and frequency of OCS were not by themselves a catalyst for surgery. A number of catalysts, including abnormal OCS test results, and secondary considerations, such as age-related factors, were found to prompt surgery. The emotional impact of discontinuing OCS following BSO varied between relief, acceptance, and loss of reassurance. OCS appears to be an acceptable risk management strategy under certain circumstances, but varying factors can prompt the decision to opt instead for BSO. The complexity of this management change decision should not be underestimated and needs to be taken into account by clinicians assisting women making choices. These findings highlight the importance of the timing of decision-making about BSO and that risk management options need routine reconsideration, through clinical discussions, information and support.

Thoracic spinal anesthesia is safe for patients undergoing abdominal cancer surgery  

PubMed Central

Aim: A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Background: Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can’t tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. Materials and Methods: A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Results: Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. Conclusion: This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than general anesthesia.

Quality of life after colorectal cancer surgery in patients from University Clinical Hospital Mostar, Bosnia and Herzegovina.  

PubMed

Quality of life (QoL) has become an important outcome measure for patients with cancer, but results from population-based studies are infrequently published. The objective of this study was to asses QoL in patients who underwent the colorectal cancer (CRC) surgery and to compare it to the QoL of general population. The patients who were admitted from January 2004 until May 2006 at the Department of Gastrointestinal Surgery at the Clinical Hospital Mostar, Bosnia and Herzegovina were divided in three groups: group of CRC patients who had received surgery and as a result of surgical treatment have colostomy, group of CRC patients who had received surgery in the same period and don't have colostomy and the third group that consisted of controls. QLQ-C30 and QLQ-CR38 questionnaires by the European Organization for Cancer Research and Treatment (EORTC) were used. A total of 67 patients were included in this study, supplemented by the thirty healthy examinees. Healthy group had significantly better results in physical functioning compared with colorectal cancer patients and better results in cognitive and social functioning. Also, they reported symptoms of diarrhea and constipation less frequently than the group with colostomy and. The group with colostomy had poorer results in emotional functioning than the group without colostomy, and also reported significantly poorer results for domain "body image". Healthy group showed better results in sexual enjoinment than the patient with colorectal cancer. Patients without colostomy reported more micturition and defecation problems and female sexual problems compared to the healthy group. Generally we found that healthy population had better results than the CRC patients, while the patients with stoma had worse results than the nonstoma patients. The results presented here suggest that psychological treatment should be an integral part of the CRC treatment plan. PMID:20120395

Phase I Trial of Induction Histone Deacetylase and Proteasome Inhibition Followed by Surgery in Non-small Cell Lung Cancer  

PubMed Central

Introduction Despite complete surgical resection survival in early stage non-small cell lung cancer (NSCLC) remains poor. Based on prior pre-clinical evaluations, we hypothesized that combined induction proteasome and histone deacetylase inhibitor therapy, followed by tumor resection, is feasible. Methods A phase I clinical trial using a two-staged multiple agent design of bortezomib and vorinostat as induction therapy followed by consolidative surgery in patients with NSCLC was performed. Standard toxicity and MTD were examined. Pre- and post-treatment tumor gene expression arrays were performed and analyzed. Pre- and post-treatment FDG-PET imaging was used to assess tumor metabolism. Finally, serum 20S proteasome levels were analyzed with ELISA, and selected intratumoral proteins were assessed via immunohistochemistry. Results Thirty-four patients were consented with 21 patients enrolling in the trial. One patient withdrew early secondary to disease progression. The MTD was bortezomib 1.3 mg/m2 and vorinostat 300 mg BID given. There were (2) grade III dose-limiting toxicities of fatigue and hypophosphatemia that were self-limited. There was no mortality. Thirty percent (6/20) of patients had greater than 60% histologic necrosis of their tumor following treatment, with two having ?90% tumor necrosis. Tumor metabolism, 20S proteasome activity, and specific protein expression did not demonstrate consistent results. Gene expression arrays comparing pre- and post-therapy NSCLC specimens revealed robust intratumoral changes in specific genes. Conclusions Induction bortezomib and vorinostat therapy followed by surgery in patients with operable NSCLC is feasible. Correlative gene expression studies suggest new targets and cell signaling pathways that may be important in modulating this combined therapy. PMID:23059775

The correlates of benefit from neoadjuvant chemotherapy before surgery in non-small-cell lung cancer: a metaregression analysis  

PubMed Central

Background Although neoadjuvant chemotherapy (NCT) is widely used, it is not clear which subgroup of locally advanced non-small-cell lung cancer (NSCLC) patients should be treated with this approach, and if a particular benefit associated with NCT exists. In this study, we aimed to investigate the potential correlates of benefit from NCT in patients with NSCLC. Methods All randomized clinical trials (RCTs) utilizing a NCT arm (without radiotherapy) versus a control arm before surgery were included for metaregression analysis. All regression analyses were weighed for trial size. Separate analyses were conducted for trials recruiting patients with different stages of disease. Previously published measures of treatment efficacy were used for the purpose of this study, regardless of being published in full text or abstract form. Results A total of 14 RCTs, consisting of 3,615 patients, were selected. Histology, stage, various characteristics of the NCT protocol, and different trial features including trial quality score were not associated with the benefit of NCT. However, in trials of stage 3 disease only, there was a greater benefit in terms of reduction in mortality from NCT, if protocols with three chemotherapeutics were used (B?=??0.18, t?=??5.25, P?=?0.006). Conclusions We think that patients with stage 3 NSCLC are served better with NCT before surgery if protocols with three chemotherapy agents or equally effective combinations are used. In addition, the effect of neoadjuvant chemotherapy is consistent with regard to disease and patient characteristics. This finding should be tested in future RCTs or individual patient data meta-analyses. PMID:22877422

Do metastatic colorectal cancer patients who present with late relapse after curative surgery have a better survival?  

PubMed Central

Background: Patients who relapse after potentially curative surgery for colorectal cancer tend to relapse within 5 years. There is, however, a group of patients who relapse beyond 5 years after resection and this late relapsing group may have a different behaviour and prognosis. Methods: We analysed data from a prospective population-based registry to compare the characteristics and survival of relapsed patients with metachronous mCRC. Patients were categorised into relapse at <2, 2–5 and >5 years following their initial surgery. Univariate log-rank tests and multivariate Cox regression was performed to determine whether time to relapse (TTR) and other factors were associated with overall survival (OS). Results: A total of 750 metachronous mCRC patients were identified. In all, 56% relapsed ?2 years, 32.4% at 2–5 years and 11.6% >5 years. Median survival time from the time of diagnosis of mCRC for the three groups was 17.6, 26.1 and 27.5 months, respectively. Short TTR (<2 years) was significantly associated with survival (HR=0.75, 95% confidence interval (CI)=0.60–0.93 and HR=0.73, 95% CI=0.53–1.01, respectively, for 2–5 and >5 years vs <2 years, P<0.05). However, there was no significant difference in survival between patients who relapsed at 5 years or later compared with those who relapsed between 2 and 5 years (HR=0.98, 95% CI=0.69–1.38, P=0.90). Conclusion: TTR within 2 years is an independent predictor of shorter survival time for mCRC patients who experience a relapse. These data do not support the hypothesis that patients who have late relapse late (>5 years) have a ‘better' biology or survival compared with patients with a TTR of 2–5 years. PMID:23860523

Respiration-induced movement correlation for synchronous noninvasive renal cancer surgery.  

PubMed

Noninvasive surgery (NIS), such as high-intensity focused ultrasound (HIFU)-based ablation or radiosurgery, is used for treating tumors and cancers in various parts of the body. The soft tissue targets (usually organs) deform and move as a result of physiological processes such as respiration. Moreover, other deformations induced during surgery by changes in patient position, changes in physical properties caused by repeated exposures and uncertainties resulting from cavitation also occur. In this paper, we present a correlation-based movement prediction technique to address respiration-induced movement of the urological organs while targeting through extracorporeal trans-abdominal route access. Among other organs, kidneys are worst affected during respiratory cycles, with significant three-dimensional displacements observed on the order of 20 mm. Remote access to renal targets such as renal carcinomas and cysts during noninvasive surgery, therefore, requires a tightly controlled real-time motion tracking and quantitative estimate for compensation routine to synchronize the energy source(s) for precise energy delivery to the intended regions. The correlation model finds a mapping between the movement patterns of external skin markers placed on the abdominal access window and the internal movement of the targeted kidney. The coarse estimate of position is then fine-tuned using the Adaptive Neuro-Fuzzy Inference System (ANFIS), thereby achieving a nonlinear mapping. The technical issues involved in this tracking scheme are threefold: the model must have sufficient accuracy in mapping the movement pattern; there must be an image-based tracking scheme to provide the organ position within allowable system latency; and the processing delay resulting from modeling and tracking must be within the achievable prediction horizon to accommodate the latency in the therapeutic delivery system. The concept was tested on ultrasound image sequences collected from 20 healthy volunteers. The results indicate that the modeling technique can be practically integrated into an image-guided noninvasive robotic surgical system with an indicative targeting accuracy of more than 94%. A comparative analysis showed the superiority of this technique over conventional linear mapping and modelfree blind search techniques. PMID:22828843

The Efficacy of Arm Node Preserving Surgery Using Axillary Reverse Mapping for Preventing Lymphedema in Patients with Breast Cancer  

PubMed Central

Purpose The axillary reverse mapping (ARM) technique to identify and preserve arm nodes during sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) was developed to prevent lymphedema. The purpose of this study was to investigate the location and metastatic rate of the arm node, and to evaluate the short term incidence of lymphedema after arm node preserving surgery. Methods From January 2009 to October 2010, 97 breast cancer patients who underwent ARM were included. Blue-dye (2.5 mL) was injected into the ipsilateral upper-inner arm. At least 20 minutes after injection, SLNB or ALND was performed and blue-stained arm nodes and/or lymphatics were identified. Patients were divided into two groups, an arm node preserved group (70 patients had ALND, 10 patients had SLNB) and an unpreserved group (13 patients had ALND, 4 patients had SLNB). The difference in arm circumference between preoperative and postoperative time points was checked in both groups. Results The mean number of identified blue stained arm nodes was 1.4±0.6. In the majority of patients (92%), arm nodes were located between the lower level of the axillary vein and just below the second intercostobrachial nerve. In the arm node unpreserved group, 2 patients had metastasis in their arm node. Among ALND patients, in the arm node preserved group, the difference in arm circumference between preoperative and postoperative time points in ipsilateral and contralateral arms was 0.27 cm and 0.07 cm, respectively, whereas it was 0.47 cm and -0.03 cm in the unpreserved group; one case of lymphedema was found after 6 months. No difference was found between arm node preserved and unpreserved group among SLNB patients. Conclusion Arm node preserving was possible in all breast cancer patients with identifiable arm nodes, during ALND or SLNB, except for those with high surgical N stage, and lymphedema did not develop in patients with arm node preserving surgery.

Surgery for brain metastases.  

PubMed

The use of surgery in the treatment of brain metastases is controversial. Patients who present certain clinical characteristics may experience prolonged survival with resection compared with radiation therapy. Thus, for patients with a single metastatic lesion in the setting of well-controlled systemic cancer, surgery is highly indicated. Stereotactic radiosurgery (SRS) alone can provide a similar survival advantage, but when used as postoperative adjuvant therapy, patients experience extended survival times. Furthermore, surgery remains the only treatment option for patients with life-threatening neurological symptoms, who require immediate tumor debulking. Treatment of brain metastases requires a careful clinical assessment of individual patients, as different prognostic factors may indicate various modes or combinations of therapy. Since surgery is an effective method for achieving tumor management in particular cases, it remains an important consideration in the treatment algorithm for brain metastases. PMID:23717791

Carcinoembryonic Antigen as a Predictor of Pathologic Response and a Prognostic Factor in Locally Advanced Rectal Cancer Patients Treated With Preoperative Chemoradiotherapy and Surgery  

SciTech Connect

Purpose: To evaluate the role of serum carcinoembryonic antigen (CEA) as a predictor of response to preoperative chemoradiotherapy (CRT) and prognostic factor for rectal cancer. Materials and Methods: The study retrospectively evaluated 352 locally advanced rectal cancer patients who underwent preoperative CRT followed by surgery. Serum CEA levels were determined before CRT administration (pre-CRT CEA) and before surgery (post-CRT CEA). Correlations between pre-CRT CEA levels and rates of good response (Tumor regression grade 3/4) were explored. Patients were categorized into three CEA groups according to their pre-/post-CRT CEA levels (ng/mL) (Group A: pre-CRT CEA {<=} 3; B: pre-CRT CEA >3, post-CRT CEA {<=}3; C: pre- and post-CRT CEA >3 ng/mL), and their oncologic outcomes were compared. Results: Of 352 patients, good responses were achieved in 94 patients (26.7%). The rates of good response decreased significantly as the pre-CRT CEA levels became more elevated (CEA [ng/mL]: {<=}3, 36.4%; 3-6, 23.6%; 6-9, 15.6%; >9, 7.8%; p < 0.001). The rates of good response were significantly higher in Group A than in Groups B and C (36.4% vs. 17.3% and 14.3%, respectively; p < 0.001). The 3-year disease-free survival rate was significantly better in Groups A and B than in Group C (82% and 79% vs. 57%, respectively; p = 0.005); the CEA grouping was identified as an independent prognostic factor (p = 0.025). Conclusions: In locally advanced rectal cancer patients, CEA levels could be of clinical value as a predictor of response to preoperative CRT and as an independent prognostic factor after preoperative CRT and curative surgery.

Cost Modeling of Preoperative Axillary Ultrasound and Fine-Needle Aspiration to Guide Surgery for Invasive Breast Cancer  

PubMed Central

Purpose Preoperative axillary lymph node ultrasound (US) and fine-needle aspiration (FNA) biopsy can identify a proportion of node-positive patients and avoid sentinel lymph node (SLN) surgery and direct surgical treatment. We compared the costs with preoperative US/FNA to without US/FNA (standard of care) for invasive breast cancer. Methods Using decision-analytic software we constructed a model to assess the costs associated with the two preoperative strategies. Diagnostic test sensitivities and specificities were obtained from literature review. Costs were derived from Medicare payment rates and actual resource utilization. Base-case results were fully probabilistic to capture parameter uncertainty in economic results. Results Base-case results estimate total mean costs per patient of $10,947 (“$” indicates US dollars throughout) with the US/FNA strategy and $10,983 with standard of care, an incremental cost savings of $36, on average, per patient [95% confidence interval (CI) of cost difference: ?$248 to $179]. Most (63%) of the simulations resulted in cost saving with axillary US/FNA. One-way sensitivity analyses suggest that results are sensitive to assumed diagnostic and surgical costs and selected diagnostic test parameters. US/FNA approach was similar in costs or cost saving relative to the standard of care for all tumor stages. Conclusions The additional cost of performing axillary US with possible FNA in every patient is balanced, on average, by the savings from avoiding SLN in cases where metastasis can be documented preoperatively. Routine use of preoperative axillary US with FNA to guide surgical planning can decrease the overall cost of patient care for invasive breast cancer. PMID:20127185

Intensity-Modulated Whole Abdominal Radiotherapy After Surgery and Carboplatin/Taxane Chemotherapy for Advanced Ovarian Cancer: Phase I Study  

SciTech Connect

Purpose: To assess the feasibility and toxicity of consolidative intensity-modulated whole abdominal radiotherapy (WAR) after surgery and chemotherapy in high-risk patients with advanced ovarian cancer. Methods and Materials: Ten patients with optimally debulked ovarian cancer International Federation of Gynecology and Obstetrics Stage IIIc were treated in a Phase I study with intensity-modulated WAR up to a total dose of 30 Gy in 1.5-Gy fractions as consolidation therapy after adjuvant carboplatin/taxane chemotherapy. Treatment was delivered using intensity-modulated radiotherapy in a step-and-shoot technique (n = 3) or a helical tomotherapy technique (n = 7). The planning target volume included the entire peritoneal cavity and the pelvic and para-aortal node regions. Organs at risk were kidneys, liver, heart, vertebral bodies, and pelvic bones. Results: Intensity-modulated WAR resulted in an excellent coverage of the planning target volume and an effective sparing of the organs at risk. The treatment was well tolerated, and no severe Grade 4 acute side effects occurred. Common Toxicity Criteria Grade III toxicities were as follows: diarrhea (n = 1), thrombocytopenia (n = 1), and leukopenia (n = 3). Radiotherapy could be completed by all the patients without any toxicity-related interruption. Median follow-up was 23 months, and 4 patients had tumor recurrence (intraperitoneal progression, n = 3; hepatic metastasis, n = 1). Small bowel obstruction caused by adhesions occurred in 3 patients. Conclusions: The results of this Phase I study showed for the first time, to our knowledge, the clinical feasibility of intensity-modulated whole abdominal radiotherapy, which could offer a new therapeutic option for consolidation treatment of advanced ovarian carcinoma after adjuvant chemotherapy in selected subgroups of patients. We initiated a Phase II study to further evaluate the toxicity of this intensive multimodal treatment.

The role of surgery in the current management of differentiated thyroid cancer.  

PubMed

In the last decades, a surprising increased incidence of differentiated thyroid cancer (DTC), along with a precocious diagnosis of "small" tumors and microcarcinomas have been observed. In these cases, better oncological outcomes are expected, and a "tailored" and "less aggressive" multimodal therapeutic protocol should be considered, avoiding an unfavorable even if minimal morbidity following an "overtreatment." In order to better define the most suitable surgical approach, its benefits and risks, we discuss the role of surgery in the current management of DTCs in the light of data appeared in the literature. Even if lymph node metastases are commonly observed, and in up to 90 % of DTC cases micrometastases are reported, the impact of lymphatic involvement on long-term survival is still argument of intensive research, and indications and extension of lymph node dissection (LD) are still under debate. In particular, endocrine and neck surgeons are still divided between proponents and opponents of routine central LD (RCLD). Considering the available evidence, there is agreement about total thyroidectomy, therapeutic LD in clinically node-positive DTC patients, and RCLD in "high risk" cases. Nevertheless, indications to the best surgical treatment of clinically node-negative "low risk" patients are still subject of research. Considering on the one hand, the recent trend toward routine central lymphadenectomy, avoiding radioactive treatment, and on the other hand, the satisfactory results obtained reserving prophylactic LD to "high risk" patients, we think that further prospective randomized trials are needed to evaluate the best choice between the different surgical approaches.

Designing a wearable navigation system for image-guided cancer resection surgery.  

PubMed

A wearable surgical navigation system is developed for intraoperative imaging of surgical margin in cancer resection surgery. The system consists of an excitation light source, a monochromatic CCD camera, a host computer, and a wearable headset unit in either of the following two modes: head-mounted display (HMD) and Google glass. In the HMD mode, a CMOS camera is installed on a personal cinema system to capture the surgical scene in real-time and transmit the image to the host computer through a USB port. In the Google glass mode, a wireless connection is established between the glass and the host computer for image acquisition and data transport tasks. A software program is written in Python to call OpenCV functions for image calibration, co-registration, fusion, and display with augmented reality. The imaging performance of the surgical navigation system is characterized in a tumor simulating phantom. Image-guided surgical resection is demonstrated in an ex vivo tissue model. Surgical margins identified by the wearable navigation system are co-incident with those acquired by a standard small animal imaging system, indicating the technical feasibility for intraoperative surgical margin detection. The proposed surgical navigation system combines the sensitivity and specificity of a fluorescence imaging system and the mobility of a wearable goggle. It can be potentially used by a surgeon to identify the residual tumor foci and reduce the risk of recurrent diseases without interfering with the regular resection procedure. PMID:24980159

[Quality of life of patients after restorative surgery for cancer of the rectum].  

PubMed

During the last decades surgeons have put a tremendous effort to perform low anterior resection (LAR) as a curative procedure for rectal cancer treated classically by abdomino-perineal resection (APR) and permanent colostomy. A psychological evaluation testing the multi-dimensional concept of quality of life was done in 32 patients (M = 21; F = 11) treated by APR and compared to 28 patients (M = 16; F = 12) treated by LAR. Patients were assessed for quality of life on the following dimensions: physical well-being, psychological well-being, dietary habits, surgical response, social concerns, body image, stress and marital adjustment. Using as covariables social support and time elapsed since surgery, a covariate analysis was used to determine the presence of group ans sex interaction. Patients with LAR had a better body image (p.001), dietary habits (p.003) and tolerance to stress (p.004). Better global quality of life (p.001), physical well being (p.001) and less surgical sequela (p.001) were found with LAR in women only. No significant difference was found on psychological well being, social concerns and marital adjustment in both surgical groups. PMID:1299163

Comparing methods of ileostomy closure constructed in colorectal surgery in Turkey  

PubMed Central

Introduction Stoma construction is a life saver method for emergent and elective operations in colorectal surgery. However, they are associated with high rates of morbidity and mortality. Aim To compare the operative findings, early postoperative complications, and costs of stapled and hand-sewn closures in loop ileostomies that are constructed in emergent and elective colorectal surgery. Material and methods The data of 68 patients requiring loop ileostomies during colorectal surgery were retrospectively evaluated. SPSS (version 20) was used for data analysis. Results The study group consisted of 44 men and 24 women with a mean age of 55.5 years. The ileostomy closures were performed with hand-sewn method in 36 patients (group 1) and stapled method in 32 patients (group 2). The mean operation time was 75.4 min in group 1 and 46.7 min in group 2 (p < 0.001). Early postoperative complications were wound infection (8.8%), small bowel obstruction (6.06%), and anastomotic leakage (2.9%). Total costs, flatulence and faeces outlet time, oral feeding starting time, time of hospital stay, and early postoperative complications were lower in the stapled group. Conclusions Morbidity and mortality rates of stoma construction and its closure are still considerable. Lower anastomotic leakage rate, complication rate, and costs and shorter operative times in the stapled group make this method preferable.

Intravascular Microdialysis as a Method for Measuring Glucose and Lactate during and after Cardiac Surgery  

PubMed Central

Background The aim was to evaluate intravascular microdialysis as a method for measuring blood glucose and lactate in a clinical setting during and after cardiac surgery. Methods Ten patients undergoing cardiac surgery were included. A microdialysis catheter was percutaneously placed in the superior vena cava or right atrium. Glucose and lactate values measured by the microdialysis technique were analyzed and compared with reference methods, i.e., arterial and venous blood gas values, once every hour up to 24 hours postoperatively. Laboratory plasma glucose was additionally analyzed every 4 hours for reference value. Results Mean absolute differences were low between microdialysis and reference methods for both glucose and lactate values. All microdialysis glucose values were in the clinically acceptable zone of error grid analysis when compared with plasma glucose values. Accuracy of glucose values was 92% according to International Organization for Standardization criteria. Conclusions Intravascular microdialysis is a novel and promising technique for real-time and accurate measurement of glucose and lactate during and after open heart surgery. Development of sensor technology may allow for continuous measurement of blood glucose and lactate using intravascular microdialysis. PMID:22027302

Prevention of Bile Leak after Liver Surgery: A Fool-proof Method  

PubMed Central

Background/Aim: Bile leak is not uncommon after liver surgeries. There is no adequate method described to prevent this morbid complication. Materials and Methods: At the end of the liver procedure, transcystic normal saline was injected under pressure with distal clamping. Leaking saline on the cut surface of the liver was sutured. The process was repeated till no leaking was observed. A suction drain was kept for any bile leak. Results: Open liver resection and hydatid cyst surgery cases were included. There were 24 cases, with 13 males and 11 females. The age range was from 4 to 80 years, with a mean of 48 years (SD ± 17.7). The number of leak sites that could be sutured were 0-4 (mean of 2.3 ± 0.5). None had bile leak postoperatively. Conclusion: Transcystic injection under pressure with distal clamping demonstrates the leak sites. Suturing them prevents the postoperative bile leak. PMID:19568579

MicroRNA-218 is upregulated in gastric cancer after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and increases chemosensitivity to cisplatin  

PubMed Central

AIM: To investigate the molecular mechanisms of miRNA in advanced gastric cancers (AGCs) before and after cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: A miRNA microarray containing human mature and precursor miRNA sequences was used to compare expression profiles in serum samples of 5 patients with AGC before and after CRS + HIPEC. The upregulation of miR-218 was confirmed by real-time reverse transcription polymerase chain reaction and its expression was analyzed in SGC7901 gastric cancer cells. RESULTS: miRNA microarray chip analysis found that the level of miR-218 expression was upregulated more than 8 fold after CRS + HIPEC. Furthermore, miR-218 increased gastric cancer cell chemosensitivity to cisplatin in vitro and inhibited gastric cell tumor growth in nude mice in vivo (0.5 vs 0.78, P < 0.05). CONCLUSION: Our results indicated that targeting miR-218 may provide a strategy for blocking the development of gastric cancer and reverse the multi-drug resistance of gastric cell lines.

Fourth versus eighth week surgery after neoadjuvant radiochemotherapy in T3-4/N0+ rectal cancer: Istanbul R-01 study  

PubMed Central

Background and purpose The optimum duration between neoadjuvant radiochemotherapy and transmesorectal excision in locally advanced rectal cancer has not been defined yet. This randomized study was designed to compare the efficacy of four-week versus eight-week delay before surgery. Methods One-hundred and fifty-three patients with locally advanced low- or mid-rectum rectal adenocarcinoma were included in this single center prospective randomized trial. Patients were assigned to receive surgical treatment after either four weeks or eight weeks of delay after chemoradiotherapy. Patients were followed for local recurrence and survival, and surgical specimens were examined for pathological staging and circumferential margin positivity. Results 4-week and 8-week groups did not differ with regard to lateral surgical margin positivity (9.2% vs. 5.1%, P=0.33, respectively), pathological tumor regression rate (P=0.90), overall survival (5-year, 76.5% vs. 74.2%, P=0.60) and local recurrence rate (11.8% vs. 10.3%, 0.77). Overall survival was better in patients with negative surgical margins (78.8% vs. 53.0%, P=0.04). Local recurrence rate was significantly higher among patients with positive surgical margin (28.5% vs. 9.3%, P=0.02). Conclusions Intentional prolongation of the chemoradiotherapy-surgery interval does not seem to improve clinical outcomes of patients with locally advanced rectal cancer. Surgical margin positivity seems to be more important with this regard. PMID:24490038

Sphincter-preserving surgery after preoperative radiochemotherapy for T3 low rectal cancers  

PubMed Central

The aim of this study was to evaluate the feasibility and the effectiveness of preoperative radiochemotherapy followed by total mesorectal excision (TME) and sphincter-preserving procedures for T3 low rectal cancer. Patients with rectal cancer and T3 tumors located within 1–6 cm of the dentate line received preoperative radiochemotherapy. Concurrent 5-fluorouracil-based radiochemotherapy was used. Radical resection with TME and sphincter-preserving procedures were performed during the six to eight weeks following radiotherapy. Survival was analyzed using the Kaplan-Meier method. The anal function was evaluated using the Wexner score. The clinical response rate was 83.5%, overall downstaging of T classification was 75.3% and pathological complete response was 15.3%. The anastomotic fistula rate was 4.7%. A median follow-up of 30 months showed the local recurrence rate to be 4.7% and the distant metastasis rate to be 5.9%. The three-year overall survival rate was 87%. The degree of anal incontinence as measured using the Wexner score decreased over time, and the anal sphincter function in the majority of patients gradually improved. Preoperative radiochemotherapy was found to improve tumor downstaging, reduces local recurrence, increase the sphincter preservation rate, and is therefore of benefit to patients with T3 low rectal cancer.

The likelihood of radiation pneumonitis and factors associated with its development in breast cancer patients treated with conservative surgery and radiation therapy have not been well established. To assess these, the authors retrospectively reviewed 1624 patients treated between 1968 and 1985. Median follow-up for patients without local or distant failure was 77 months. Patients were treated with either tangential fields alone (n = 508) or tangents with a third field to the supraclavicular (SC) or SC-axillary (AX) region (n = 1116). Lung volume treated in the tangential fields was generally limited by keeping the perpendicular distance (demagnified) at the isocenter from the deep field edges to the posterior chest wall (CLD) to 3 cm or less. Seventeen patients with radiation pneumonitis were identified (1.0%). Radiation pneumonitis was diagnosed when patients presented with cough (15/17, 88%), fever (9/17, 53%), and/or dyspnea (6/17, 35%) and radiographic changes (17/17) following completion of RT. Radiographic infiltrates corresponded to treatment portals in all patients, and in 12 of the 17 patients, returned to baseline within 1-12 months. Five patients had permanent scarring on chest X ray. No patient had late or persistent pulmonary symptoms. The incidence of radiation pneumonitis was correlated with the combined use of chemotherapy (CT) and a third field. Three percent (11/328) of patients treated with a 3-field technique who received chemotherapy developed radiation pneumonitis compared to 0.5% (6 of 1296) for all other patients (p = 0.0001). When patients treated with a 3-field technique received chemotherapy concurrently with radiation therapy, the incidence of radiation pneumonitis was 8.8% (8/92) compared with 1.3% (3/236) for those who received sequential chemotherapy and radiation therapy (p = 0.002).

Compositions and methods for cancer treatment using targeted carbon nanotubes  

DOEpatents

The present invention is a method for detecting and destroying cancer tumors. The method is based on the concept of associating a linking protein or linking peptide such as, but not limited to, annexin V or other annexins to carbon nanotubes such as single-walled carbon nanotubes (SWNTs) to form a protein-CNT complex. Said linking protein or peptide can selectively bind to cancerous cells, especially tumor vasculature endothelial cells, rather than to healthy ones by binding to cancer-specific external receptors such as anionic phospholipids including phosphatidylserine expressed on the outer surfaces of cancer cells only. Irradiation of bound CNTs with one or more specific electromagnetic wavelengths is then used to detect and destroy those cells to which the CNTs are bound via the linking protein or peptide thereby destroying the tumor or cancer cells and preferably an immunostimulant is provided to the patient to enhance the immune response against antigens released from the tumor or cancer cells.

The Use of Ovarian Cancer Cells from Patients Undergoing Surgery to Generate Primary Cultures Capable of Undergoing Functional Analysis  

PubMed Central

The use of cell lines or animal models has significant disadvantages when dealing with a set of heterogeneous diseases such as epithelial ovarian cancer. This has clinical relevance in that biomarkers developed using cell line or animal models are often not transferable to the clinical setting. In this study, we describe the development of a robust protocol for developing primary cultures of ovarian cancer which will overcome some of these difficulties. Women undergoing surgery for ovarian cancer were recruited and samples of ascites and solid tumour deposits were used to develop primary cultures. Cells were characterised using a panel of immunofluorescent antibodies prior to use in a variety of assays including functional assessment of DNA repair pathways. During the four year study period, viable cultures, confirmed to be epithelial in origin were generated from 156 of 172 (91%) cases recruited. Characterisation was carried out using a panel of antibodies including pancytokeratin, CA125, EpCAM, MOC-31, D2-40 and vimentin. Senescence occurred between the 2nd and 8th passages in all cultures except one in which spontaneous immortalization occurred. Cells could be successfully cultured even after a period of storage at 4°C and cultured cells were capable of being used for a variety of applications including functional assays. Upon functional assessment there was minimal intra-tumour heterogeneity. It is therefore possible to derive viable ovarian cancer cell cultures in the majority of patients undergoing surgery. Cells cultured directly from patient cancers provide an accurate and highly diverse model. PMID:24603616

[Methods and results of smoking cessation in cancer smoker's].  

PubMed

Tobacco prevention is the most effective prevention of cancer. Daily smoking promotes tumor progression, increases the risk of second cancer and decreases survival. The diagnosis of smoking and support for cessation and preventing recurrence is an integral part of cancer treatment. Smoking increases side effects of chemotherapy and surgery and reduces the effectiveness of radiotherapy and chemotherapy. Smokers with cancer do not smoke by life-style choice but because they are highly addicted and are suffering from a chronic relapsing disease: tobacco dependence, which justifies intensive medical management. The oncologist himself may perform this support or coordinate with other physicians in charge of the patient or with a tobacco cessation clinic, but patients are often unable to stop alone, as evidenced by the continued to use tobacco despite a cancer diagnosis. Treatment will always include a therapeutic education, compartmental behavioral therapy and medication. The patches and oral nicotine replacement or varenicline are the two most effective treatments that can be prescribed to smokers suffering of cancer, without including those with any motivation to quit. Smoking reducing occurred in a few days or weeks on treatment will allow them to reconsider the judgment. The full stop is always the goal for the doctor, even if it is not the patient initial goal. After stopping, the patient is not cured but still a patient with tobacco dependence who does not smoke. The risk of relapse in the year being 50%. The cancer patient management will use every visit to the point tobacco dependence and prevent relapse, alone or with assistance of a specialist. There is a lack of data on smoking cessation in cancer patients, but no item calls for a three-month quit rate of 50% as observed in the general population after an optimal management of tobacco cessation.

Influence of data quality on computed Dutch hospital quality indicators: a case study in colorectal cancer surgery  

PubMed Central

Background Our study aims to assess the influence of data quality on computed Dutch hospital quality indicators, and whether colorectal cancer surgery indicators can be computed reliably based on routinely recorded data from an electronic medical record (EMR). Methods Cross-sectional study in a department of gastrointestinal oncology in a university hospital, in which a set of 10 indicators is computed (1) based on data abstracted manually for the national quality register Dutch Surgical Colorectal Audit (DSCA) as reference standard and (2) based on routinely collected data from an EMR. All 75 patients for whom data has been submitted to the DSCA for the reporting year 2011 and all 79 patients who underwent a resection of a primary colorectal carcinoma in 2011 according to structured data in the EMR were included. Comparison of results, investigating the causes for any differences based on data quality analysis. Main outcome measures are the computability of quality indicators, absolute percentages of indicator results, data quality in terms of availability in a structured format, completeness and correctness. Results All indicators were fully computable based on the DSCA dataset, but only three based on EMR data, two of which were percentages. For both percentages, the difference in proportions computed based on the two datasets was significant. All required data items were available in a structured format in the DSCA dataset. Their average completeness was 86%, while the average completeness of these items in the EMR was 50%. Their average correctness was 87%. Conclusions Our study showed that data quality can significantly influence indicator results, and that our EMR data was not suitable to reliably compute quality indicators. EMRs should be designed in a way so that the data required for audits can be entered directly in a structured and coded format. PMID:24721489

Feasibility of complete video-assisted thoracoscopic surgery following neoadjuvant therapy for locally advanced non-small cell lung cancer  

PubMed Central

Objective To explore the feasibility of complete video-assisted thoracoscopic surgery (c-VATS) following neoadjuvant therapy (chemotherapy, targeted therapy and radiotherapy, either alone or in combination) for the treatment of patients with non-small cell lung cancer (NSCLC). Methods The clinical data of 43 NSCLC patients undergoing c-VATS following neoadjuvant therapy were retrospectively analyzed, including the preoperative functional indicators, staging, concurrent diseases, surgical techniques, operation time, number of lymph nodes dissected and postoperative drainage time and quantity, postoperative hospital stay, postoperative complications, and survival. Results From January 2006 to March 2012, a total of 43 patients with stage IIA-IIIB NSCLC were included in this study (IIIA: 27 cases, 62.8%; IIIB: 11 cases, 25.6%), including 32 males (74.4%) and 11 females (25.6%). Forty-two patients were operated successfully, 28 underwent pulmonary lobectomies (including 9 bronchial sleeve resections), 5 had double lobectomies, 5 had wedge resections, and 4 had total pneumonectomies. Seven patients were referred to undergo Hybrid VATS (7/42, 16.7%). The mean length of the operation was 160.48±16.52 min (range, 130-180 min); the intraoperative blood loss was 253.57±117.08 mL; the number of lymph nodes dissected was 16.88±10.93; the postoperative drainage time was 1-7 d (mean: 2.62±0.96 d); and the postoperative hospital stay was 3-7 d (mean: 5.45±1.30 d). The incidence of postoperative complications was 9.5% (4/42), and the perioperative mortality was 2.4% (1/42). The 1-, 2-, and 3-year overall survival rates were 94%, 79%, and 65%, respectively. Conclusions c-VATS following neoadjuvant therapy is safe and feasible for the treatment of locally advanced NSCLC. PMID:24040535

Locoregional Recurrence of Breast Cancer in Patients Treated With Breast Conservation Surgery and Radiotherapy Following Neoadjuvant Chemotherapy  

SciTech Connect

Purpose: Breast conservation surgery (BCS) and radiotherapy (RT) following neoadjuvant chemotherapy (NCT) have been linked with high locoregional recurrence (LRR) rates and ipsilateral breast tumor recurrence (IBTR) rates. The purpose of this study was to analyze clinical outcomes in patients who exhibited LRR and IBTR after being treated by BCS and RT following NCT. Methods and Materials: In total, 251 breast cancer patients treated with BCS and RT following NCT between 2001 and 2006 were included. All patients had been shown to be clinically node-positive. Clinical stage at diagnosis (2003 AJCC) was II in 68% of patients and III in 32% of patients. Of those, 50%, 35%, and 15% of patients received anthracycline-based, taxane-based, and combined anthracycline-taxane NCT, respectively. All patients received RT. Results: During follow-up (median, 55 months), 26 (10%) patients had LRR, 19 of these patients had IBTR. Five-year actuarial rates of IBTR-free and LRR-free survival were 91% and 89%, respectively. In multivariate analyses, lack of hormone suppression therapy was found to increase both LRR and IBTR rates. Hazard ratios were 7.99 (p < 0.0001) and 4.22 (p = 0.004), respectively. Additionally, pathology stage N2 to N3 increased LRR rate (hazard ratio, 4.22; p = 0.004), and clinical AJCC stage III IBTR rate (hazard ratio, 9.05; p = 0.034). Achievement of pathological complete response and presence of multifocal tumors did not affect LRR or IBTR. Conclusions: In patients with locally advanced disease, who were clinically node-positive at presentation, BCS after NCT resulted in acceptably low rates of IBTR and LRR. Mastectomy should be considered as an option in patients who present with clinical stage III tumors or who are not treated with adjuvant hormone suppression therapy, because they exhibit high IBTR rates after NCT and BCS.

Comparing classification methods for diffuse reflectance spectra to improve tissue specific laser surgery  

PubMed Central

Background In the field of oral and maxillofacial surgery, newly developed laser scalpels have multiple advantages over traditional metal scalpels. However, they lack haptic feedback. This is dangerous near e.g. nerve tissue, which has to be preserved during surgery. One solution to this problem is to train an algorithm that analyzes the reflected light spectra during surgery and can classify these spectra into different tissue types, in order to ultimately send a warning or temporarily switch off the laser when critical tissue is about to be ablated. Various machine learning algorithms are available for this task, but a detailed analysis is needed to assess the most appropriate algorithm. Methods In this study, a small data set is used to simulate many larger data sets according to a multivariate Gaussian distribution. Various machine learning algorithms are then trained and evaluated on these data sets. The algorithms’ performance is subsequently evaluated and compared by averaged confusion matrices and ultimately by boxplots of misclassification rates. The results are validated on the smaller, experimental data set. Results Most classifiers have a median misclassification rate below 0.25 in the simulated data. The most notable performance was observed for the Penalized Discriminant Analysis, with a misclassifiaction rate of 0.00 in the simulated data, and an average misclassification rate of 0.02 in a 10-fold cross validation on the original data. Conclusion The results suggest a Penalized Discriminant Analysis is the most promising approach, most probably because it considers the functional, correlated nature of the reflectance spectra. The results of this study improve the accuracy of real-time tissue discrimination and are an essential step towards improving the safety of oral laser surgery. PMID:25030085

The JACS prospective cohort study of newly diagnosed women with breast cancer investigating joint and muscle pain, aches, and stiffness: pain and quality of life after primary surgery and before adjuvant treatment  

PubMed Central

Background Breast cancer affects one in eight UK women during their lifetime: many of these women now receive adjuvant chemotherapy and hormone therapy. Joint and muscle pains, aches, and stiffness are common but the natural history, aetiology and impact of these symptoms are unknown. A cohort study of newly diagnosed women with primary breast cancer was established to explore this. In this paper we present study methods and sample characteristics, describe participants’ experience of musculoskeletal pain at baseline interview, and explore its impact on quality of life. Methods Women with non-metastatic breast cancer were recruited following primary surgery into a multi-centre cohort study. They received questionnaires by post five times (baseline, 3, 6 , 9 and 12 months) to investigate prevalence, severity, location and correlates of musculoskeletal pain, and impact on quality-of-life. Pain was measured by the Nordic musculoskeletal questionnaire, the Brief Pain Inventory, and MSK-specific questions, and quality of life by the SF-36 and FACIT scales. Results 543 women (mean age 57 years, range 28–87, 64% postmenopausal) were recruited following surgery for primary breast cancer from breast cancer clinics in eight hospitals. Fifteen per cent of the eligible cohort was missed; 28% declined to participate. Joint or muscle aches, pains or stiffness were reported by 69% women with 28% specifically reporting joint pain/aches/stiffness. Quality of life, as measured by the FACT-B and adjusted for age, depression, surgery and analgesic use, is significantly worse in all domains in those with musculoskeletal problems than those without. Conclusions Our findings highlights the importance of a better understanding of these symptoms and their impact on the lives of women with primary breast cancer so that healthcare professionals are better equipped to support patients and to provide accurate information to inform treatment decisions. Further papers from this study will address these issues. PMID:24964929

Biologically Effective Dose-Response Relationship for Breast Cancer Treated by Conservative Surgery and Postoperative Radiotherapy  

SciTech Connect

Purpose: To find a biologically effective dose (BED) response for adjuvant breast radiotherapy (RT) for initial-stage breast cancer. Methods and Materials: Results of randomized trials of RT vs. non-RT were reviewed and the tumor control probability (TCP) after RT was calculated for each of them. Using the linear-quadratic formula and Poisson statistics of cell-kill, the average initial number of clonogens per tumor before RT and the average tumor cell radiosensitivity (alpha-value) were calculated. An {alpha}/{beta} ratio of 4 Gy was assumed for these calculations. Results: A linear regression equation linking BED to TCP was derived: -ln[-ln(TCP)] = -ln(No) + {alpha}{sup *} BED = -4.08 + 0.07 * BED, suggesting a rather low radiosensitivity of breast cancer cells (alpha = 0.07 Gy{sup -1}), which probably reflects population heterogeneity. From the linear relationship a sigmoid BED-response curve was constructed. Conclusion: For BED values higher than about 90 Gy{sub 4} the radiation-induced TCP is essentially maximizing at 90-100%. The relationship presented here could be an approximate guide in the design and reporting of clinical trials of adjuvant breast RT.

The influence of splenectomy performed simultaneously with gastrectomy on postoperative complications in patients with gastric cancer undergoing surgery with the intention to treat.  

PubMed

Abstract Despite the growing understanding of the pathophysiological processes in the perioperative period and significant advancements in surgical techniques, operative treatment for gastric cancer remains a challenge for surgeons, especially because the primary procedure of total or nearly total gastrectomy must at times be extended by the resection of other organs. The aim of the study was to asses the influence of concomitant splenectomy in patients undergoing curative surgery for gastric cancer on postoperative complications. Material and methods. The study population consisted of 258 patients who underwent surgical treatment for gastric cancer with the intention to treat. The study assessed the influence of extending the surgical intervention by splenectomy on postoperative complications, both general and surgical, including the most severe of these, i.e. oesophago-gastric anastomotic leakage, duodenal stump leakage and peritoneal fluid infections. Results. Among the 258 gastric cancer patients receiving curative surgical treatment, the most common simultaneous intervention was splenectomy: 42/258 (16.3%), which was also accompanied by partial pancreatectomy in 8 cases. The number of surgical postoperative complications, major and minor, was similar in both subgroups: with and without splenectomy. Minor general complications, such as pyrexia with no clinically apparent reason, atelectasis, pneumonia and pleural effusion were statistically significantly more common in the subgroup with splenectomy (p=0.0001). Conclusion. Splenectomy performed concomitantly with gastrectomy for gastric cancer increases the risk of minor general complications. However, it does not increase the risk of severe surgical complications, such as oesophago-intestinal anastomotic leakage and does not increase the risk of death. PMID:25222578

Spouses' perceptions of and reactions to living with a partner who has undergone surgery for rectal cancer resulting in a stoma.  

PubMed

The aim of this study was to illuminate spouses' perceptions of living with a partner who had been diagnosed with rectal cancer followed by surgery resulting in a stoma. The focus group interview was chosen as method of data collection. Two focus group interviews consisting of 2 meetings each were conducted. A qualitative content analysis was used. Five themes emerged: difficulties of being involved; living with uncertainty; learning to live in a new way; the altered body; and the search for explanations. There were feelings of anxiety about the partner's serious condition and the possible spread of the cancer. After the rehabilitation period, the stoma influenced the spouses' lives in many ways but they coped with the problems together with their partners and helped them adapt to their changed circumstances. This study indicates that the spouses were very much involved in caring for the patient suffering from rectal cancer by protecting them and showing empathy. However, the dependence on the stoma affected and restricted their family and social life. PMID:15108956

Robot-assisted laparoscopic colorectal surgery.  

PubMed

Colorectal cancer is one of the most common malignancies seen in developed countries. Its current treatment is based on a multidisciplinary approach entailing surgery, chemotherapy and radiotherapy. Surgery can be performed with open and minimal invasive methods. Single incision laparoscopic surgery (SILS), natural orifice transluminal endoscopic surgery (NOTES) and robot assisted laparoscopic surgery (RALS) are the final points to be reached in minimally invasive surgery. The first robotic colorectal surgical intervention was performed in 2001 after getting the FDA approval for the da Vinci surgical system in intraabdominal surgery, and since then, its use in this field gradually increased. Compared to open surgery, the advantage and superiority of robotic surgery, especially in narrow areas such as the pelvis, has been shown in many studies. It is a safe and feasible method. Although there are many existing studies about minimally invasive surgery, more randomized studies with larger case numbers should be carried out in order to establish the favorable oncological and functional outcomes of robotic surgery in addition to its obviously observed advantages.

A Novel Method for Implementation of Frameless StereoEEG in Epilepsy Surgery  

PubMed Central

BACKGROUND: Stereoelectroencephalography (SEEG) is an invasive diagnostic procedure in epilepsy surgery that is usually implemented with frame-based methods. OBJECTIVE: To describe a new technique of frameless SEEG and report a prospective case series at a single center. METHODS: Image integration and planning of electrode trajectories were performed preoperatively on specialized software and exported to a Medtronic S7 StealthStation. Trajectories were implemented by frameless stereotaxy using percutaneous drilling and bolt insertion. RESULTS: Twenty-two patients went this technique, with the insertion of 187 intracerebral electrodes. Of 187 electrodes, 175 accurately reached their neurophysiological target, as measured by postoperative computed tomography reconstruction and multimodal image integration with preoperative magnetic resonance imaging. Four electrodes failed to hit their target due to extradural deflection, and 3 were subsequently resited satisfactorily. Eight electrodes were off target by a mean of 3.6 mm (range, 0.9-6.8 mm) due to a combination of errors in bolt trajectory implementation and bending of the electrode. There was 1 postoperative hemorrhage that was clinically asymptomatic and no postoperative infections. Sixteen patients were offered definitive cortical resections, and 6 patients were excluded from resective surgery. CONCLUSION: Frameless SEEG is a novel and safe method for implementing SEEG and is easily translated into clinical practice.

Nested methylation-specific polymerase chain reaction cancer detection method  

DOEpatents

A molecular marker-based method for monitoring and detecting cancer in humans. Aberrant methylation of gene promoters is a marker for cancer risk in humans. A two-stage, or "nested" polymerase chain reaction method is disclosed for detecting methylated DNA sequences at sufficiently high levels of sensitivity to permit cancer screening in biological fluid samples, such as sputum, obtained non-invasively. The method is for detecting the aberrant methylation of the p16 gene, O 6-methylguanine-DNA methyltransferase gene, Death-associated protein kinase gene, RAS-associated family 1 gene, or other gene promoters. The method offers a potentially powerful approach to population-based screening for the detection of lung and other cancers.

Conservative surgery and radiotherapy for stage I/II breast cancer using lung density correction: 10-year and 15-year results  

SciTech Connect

Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age {<=} 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast cancer-specific survival, and overall survival compared with other reported series of breast-conserving surgery and RT in early-stage disease. These results will serve as a benchmark against which newer radiation delivery strategies such as intensity-modulated RT and partial breast RT can be compared.

Sarcopenia is associated with postoperative infection and delayed recovery from colorectal cancer resection surgery  

PubMed Central

Background: Skeletal muscle depletion (sarcopenia) predicts morbidity and mortality in the elderly and cancer patients. Methods: We tested whether sarcopenia predicts primary colorectal cancer resection outcomes in stage II–IV patients (n=234). Sarcopenia was assessed using preoperative computed tomography images. Administrative hospitalisation data encompassing the index surgical admission, direct transfers for inpatient rehabilitation care and hospital re-admissions within 30 days was searched for International Classification of Disease (ICD)-10 codes for postoperative infections and inpatient rehabilitation care and used to calculate length of stay (LOS). Results: Overall, 38.9% were sarcopenic; 16.7% had an infection and 9.0% had inpatient rehabilitation care. Length of stay was longer for sarcopenic patients overall (15.9±14.2 days vs 12.3±9.8 days, P=0.038) and especially in those ?65 years (20.2±16.9 days vs 13.1±8.3 days, P=0.008). Infection risk was greater for sarcopenic patients overall (23.7% vs 12.5% P=0.025), and especially those ?65 years (29.6% vs 8.8%, P=0.005). Most (90%) inpatient rehabilitation care was in patients ?65 years. Inpatient rehabilitation was more common in sarcopenic patients overall (14.3% vs 5.6% P=0.024) and those ?65 years (24.1% vs 10.7%, P=0.06). In a multivariate model in patients ?65 years, sarcopenia was an independent predictor of both infection (odds ratio (OR) 4.6, (95% confidence interval (CI) 1.5, 13.9) P<0.01) and rehabilitation care (OR 3.1 (95% CI 1.04, 9.4) P<0.04). Conclusion: Sarcopenia predicts postoperative infections, inpatient rehabilitation care and consequently a longer LOS. PMID:22871883

Thoracic metastasis in advanced ovarian cancer: comparison between computed tomography and video-assisted thoracic surgery  

PubMed Central

Objective To determine which computed tomography (CT) imaging features predict pleural malignancy in patients with advanced epithelial ovarian carcinoma (EOC) using video-assisted thoracic surgery (VATS), pathology, and cytology findings as the reference standard. Methods This retrospective study included 44 patients with International Federation of Obstetrics and Gynecology (FIGO) stage III or IV primary or recurrent EOC who had chest CT ?30 days before VATS. Two radiologists independently reviewed the CT studies and recorded the presence and size of pleural effusions and of ascites; pleural nodules, thickening, enhancement, subdiaphragmatic tumour deposits and supradiaphragmatic, mediastinal, hilar, and retroperitoneal adenopathy; and peritoneal seeding. VATS, pathology, and cytology findings constituted the reference standard. Results In 26/44 (59%) patients, pleural biopsies were malignant. Only the size of left-sided pleural effusion (reader 1: rho=-0.39, p=0.01; reader 2: rho=-0.37, p=0.01) and presence of ascites (reader 1: rho=-0.33, p=0.03; reader 2: rho=-0.35, p=0.03) were significantly associated with solid pleural metastasis. Pleural fluid cytology was malignant in 26/35 (74%) patients. Only the presence (p=0.03 for both readers) and size (reader 1: rho=0.34, p=0.04; reader 2: rho=0.33, p=0.06) of right-sided pleural effusion were associated with malignant pleural effusion. Interobserver agreement was substantial (kappa=0.78) for effusion size and moderate (kappa=0.46) for presence of solid pleural disease. No other CT features were associated with malignancy at biopsy or cytology. Conclusion In patients with advanced EOC, ascites and left-sided pleural effusion size were associated with solid pleural metastasis, while the presence and size of right-sided effusion were associated with malignant pleural effusion. No other CT features evaluated were associated with pleural malignancy. PMID:22247803

Tumor-associated macrophages in stage IIIA pN2 non-small cell lung cancer after neoadjuvant chemotherapy and surgery  

PubMed Central

Purpose: Most of the patients with stage IIIA pN2 non-small cell lung cancer (NSCLC) develop recurrence after surgery. It is not clear whether post neoadjuvant chemotherapy tumor-associated macrophages is associated with recurrence. Patients and Methods: Stage IIIA pN2 NSCLC patients underwent cisplatin/docetaxel neoadjuvant chemotherapy and surgery were retrospectively enrolled. Immunohistochemical staining of CD68 was used to identify macrophages in surgical resected stored tissues. Results: The objective response rate of cisplatin/docetaxel was 68%, overall median disease-free survival (DFS) was 13.1 months and median overall survival (OS) 36.8. months. Multiple Cox regression analysis showed low total macrophage numbers and mediastinal lymph nodes downstaging were independent factors for longer DFS, whereas high islet/stromal macrophages ratio was an independent facto for OS. In patients downstaged to pN0, low total macrophage numbers was also associated with longer DFS. Conclusions: Low total macrophage number is an independent factor for better DFS in pN2 stage IIIA NSCLC patients receiving neoadjuvant chemotherapy and surgical resection, which association was kept in those downstaged to pN0. Further studies are warrant to confirm the predictive role of TAMs and their potential causative role in tumor recurrence. PMID:25360223

[Methods and importance of volume measurement in reconstructive and aesthetic breast surgery].  

PubMed

Volume measurement of the breast allows for better surgical planning and implant selection in breast reconstructive and symmetrization procedures. The safety and accuracy of tumor removal, in accordance with oncoplastic principles, may be improved by knowing the true breast- and breast tumor volume. The authors discuss the methods of volume measurement of the breast and describe the method based on magnetic resonance imaging digital volume measurement in details. The volume of the breast parenchyma and the tumor was determined by processing the diagnostic magnetic resonance scans, and the difference in the volume of the two breasts was measured. Surgery was planned and implant selection was made based on the measured volume details. The authors conclude that digital volume measurement proved to be a valuable tool in preoperative planning of volume reducing mammaplasty, replacement of unknown size implants and in cases when breast asymmetry is treated.

Fluorine-18-fluorodeoxygglucose-guided breast cancer surgery with a positron-sensitive probe: Validation in preclinical studies  

SciTech Connect

In this study, the feasibility of utilizing 2-deoxy-2-fluoro-d-glucose (FDG) in conjunction with a positron-sensitive intraoperative probe to guide breast tumor excision was investigated. The probe was constructed with a plastic scintillator tip coupled to a photomultiplier tube with fiber optic cable. Anticipated resolution degradation was evaluated by measurement of line spread functions in the presence of background radiation. Realistic photon background distributions were simulated with a human torso phantom and a cardiac insert. The relationship between resolution and energy threshold was measured to find the optimal discriminator settings. In addition, probe sensitivity as a function of energy threshold was determined for various size-simulated tumors. Finally, the ability to localize breast cancers in vivo was tested in a rodent model. Mammary rat tumors implanted in Lewis rats were examined after injection with FDG; these results were correlated with those of histologic analyses. Measurements of line spread functions indicated that resolution could be maximized in a realistic background photon environment by increasing the energy threshold to levels at or above the Compton continuum edge (340 keV). At this setting, the probe`s sensitivity was determined to be 58 and 11 cps/{mu}Ci for 3.18- and 6.35-mm diameter simulated tumors, respectively. Probe readings correlated well with histologic results; the probe was generally able to discriminate between tumor and normal tissue. This study indicates that breast cancer surgery guided by a positron-sensitive probe warrants future evaluation in breast-conserving surgery of patients with breast cancer. 23 refs., 5 figs.

Tension Subcutaneous Emphysema during Laparoscopic Surgery Treatment of Colon Cancer: A Case Report.  

PubMed

Carbon dioxide (CO2) insufflation is now essential for most endoscopic surgeries, such as abdominal, pelvic, and neck endoscopic surgery. It is not uncommon for CO2 leaks to occur unintentionally into subcutaneous tissue, later diffusing into a patient's bloodstream and resulting in hypercarbia. Regardless of the etiology of subcutaneous emphysema, a similar clinical management is required. Herein, we report on a case of tension subcutaneous emphysema and subsequent fatal ventilatory failure due to massive subcutaneous emphysema during laparoscopy. A timely blowhole incision is an effective intervention in an emergent setting like this case, although the patient had endotracheal intubation. PMID:23180428

Estrogen-Dependent Prognostic Significance of Cyclooxygenase-2 Expression in Early-Stage Invasive Breast Cancers Treated With Breast-Conserving Surgery and Radiation  

SciTech Connect

Purpose: To evaluate the prognostic significance of cyclooxygenase-2 (COX-2) in breast cancer patients treated with conservative surgery and radiation therapy (CS+RT). Methods and Materials: Between 1975 and 2003, we retrieved specimens from 504 breast cancer patients treated with CS+RT. The specimens were constructed into tissue microarrays processed and stained for estrogen receptor (ER), progesterone receptor, Her2/neu, and COX-2. Each core was scored as positive or negative. All data including demographics, clinical, pathologic, staging, and outcome variables were entered into a computerized database. Results: Expression of COX-2 was positive in 58% of cases and correlated with younger age (p = 0.01) and larger tumor size (p 0.001). Expression of COX-2 was predictive of local relapse (relative risk[RR], 3.248; 95% confidence interval [CI], 1.340-7.871; p = 0.0091), distant metastasis (RR, 2.21; 95% CI, 1.259-3.896; p = 0.0058), and decreased survival (RR, 2.321; 95% CI, 1.324-4.071; p = 0.0033). Among ER-positive patients, COX-2 expression was predictive of worse local control (85% vs. 93%, p = 0.04), distant metastasis (75% vs. 95%, p = 0.002) and worse survival (65% vs. 94%, p = 0.002). Among ER-negative tumors COX-2 expression was not significantly correlated with local control (87 vs. 95%, p = 0.12), distant metastasis (73% vs. 78%, p = 0.39), or survival (77% vs. 87%, p 0.15). Conclusions: In breast cancer patients treated with CS+RT, COX-2 expression is associated with younger age, larger tumor size, worse local control, distant metastasis, and worse overall survival. The significance is limited to hormone receptor-positive tumors, consistent with the known effect of COX-2/PGE2 on aromatase activity. Use of COX-2 inhibitors in estrogen-dependent breast cancers warrants further investigation.

Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy Improves Survival for Patients with Peritoneal Carcinomatosis from Colorectal Cancer: A Phase II Study from a Chinese Center  

PubMed Central

Background Peritoneal carcinomatosis (PC) is a difficult clinical challenge in colorectal cancer (CRC) because conventional treatment modalities could not produce significant survival benefit, which highlights the acute need for new treatment strategies. Our previous case-control study demonstrated the potential survival advantage of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) over CRS alone. This phase II study was to further investigate the efficacy and adverse events of CRS+HIPEC for Chinese patients with CRC PC. Methods A total of 60 consecutive CRC PC patients underwent 63 procedures consisting of CRS+HIPEC and postoperative chemotherapy, all by a designated team focusing on this combined treatment modality. All the clinico-pathological information was systematically integrated into a prospective database. The primary end point was disease-specific overall survival (OS), and the secondary end points were perioperative safety profiles. Results By the most recent database update, the median follow-up was 29.9 (range 3.5–108.9) months. The peritoneal cancer index (PCI) ?20 was in 47.0% of patients, complete cytoreductive surgery (CC0-1) was performed in 53.0% of patients. The median OS was 16.0 (95% confidence interval [CI] 12.2–19.8) months, and the 1-, 2-, 3-, and 5-year survival rates were 70.5%, 34.2%, 22.0% and 22.0%, respectively. Mortality and grades 3 to 5 morbidity rates in postoperative 30 days were 0.0% and 30.2%, respectively. Univariate analysis identified 3 parameters with significant effects on OS: PCI ?20, CC0-1 and adjuvant chemotherapy over 6 cycles. On multivariate analysis, however, only CC0-1 and adjuvant chemotherapy ?6 cycles were found to be independent factors for OS benefit. Discussion CRS+HIPEC at a specialized treatment center could improve OS for selected CRC PC patients from China, with acceptable perioperative safety. PMID:25259574

Brain Metastases in Gastrointestinal Cancers: Is there a Role for Surgery?  

PubMed Central

About 10% of all cancer patients will develop brain metastases during advanced disease progression. Interestingly, the vast majority of brain metastases occur in only three types of cancer: Melanoma, lung and breast cancer. In this review, we focus on summarizing the prognosis and impact of surgical resection of brain metastases originating from gastrointestinal cancers such as esophageal, gastric, pancreatic and colorectal cancer. The incidence of brain metastases is <1% in pancreatic and gastric cancer and <4% in esophageal and colorectal cancer. Overall, prognosis of these patients is very poor with a median survival in the range of only months. Interestingly, a substantial number of patients who had received surgical resection of brain metastases showed prolonged survival. However, it should be taken into account that all these studies were not randomized and it is likely that patients selected for surgical treatment presented with other important prognostic factors such as solitary brain metastases and exclusion of extra-cranial disease. Nevertheless, other reports have demonstrated long-term survival of patients upon resection of brain metastases originating from gastrointestinal cancers. Thus, it appears to be justified to consider aggressive surgical approaches for these patients. PMID:25247579

Investigation of clinical and dosimetric factors associated with postoperative pulmonary complications in esophageal cancer patients treated with concurrent chemoradiotherapy followed by surgery  

SciTech Connect

Purpose: To assess the association of clinical and especially dosimetric factors with the incidence of postoperative pulmonary complications among esophageal cancer patients treated with concurrent chemoradiation therapy followed by surgery. Method and Materials: Data from 110 esophageal cancer patients treated between January 1998 and December 2003 were analyzed retrospectively. All patients received concurrent chemoradiotherapy followed by surgery; 72 patients also received irinotecan-based induction chemotherapy. Concurrent chemotherapy was 5-fluorouracil-based and in 97 cases included taxanes. Radiotherapy was delivered to a total dose of 41.4-50.4 Gy at 1.8-2.0 Gy per fraction with a three-dimensional conformal technique. Surgery (three-field, Ivor-Lewis, or transhiatal esophagectomy) was performed 27-123 days (median, 45 days) after completion of radiotherapy. The following dosimetric parameters were generated from the dose-volume histogram (DVH) for total lung: lung volume, mean dose to lung, relative and absolute volumes of lung receiving more than a threshold dose (relative V{sub dose} and absolute V{sub dose}), and absolute volume of lung receiving less than a threshold dose (volume spared, or VS{sub dose}). Occurrence of postoperative pulmonary complications, defined as pneumonia or acute respiratory distress syndrome (ARDS) within 30 days after surgery, was the endpoint for all analyses. Fisher's exact test was used to investigate the relationship between categorical factors and incidence of postoperative pulmonary complications. Logistic analysis was used to analyze the relationship between continuous factors (e.g., V{sub dose} or VS{sub dose}) and complication rate. Logistic regression with forward stepwise inclusion of factors was used to perform multivariate analysis of those factors having univariate significance (p < 0.05). The Mann-Whitney test was used to compare length of hospital stay in patients with and without lung complications and to compare lung volumes, VS5 values, and absolute and relative V5 values in male vs. female patients. Pearson correlation analysis was used to determine correlations between dosimetric factors. Results: Eighteen (16.4%) of the 110 patients developed postoperative pulmonary complications. Two of these died of progressive pneumonia. Hospitalizations were significantly longer for patients with postoperative pulmonary complications than for those without (median, 15 days vs. 11 days, p = 0.003). On univariate analysis, female gender (p = 0.017), higher mean lung dose (p = 0.036), higher relative volume of lung receiving {>=}5 Gy (V5) (p = 0.023), and smaller volumes of lung spared from doses {>=}5-35 Gy (VS5-VS35) (p < 0.05) were all significantly associated with an increased incidence of postoperative pulmonary complications. No other clinical factors were significantly associated with the incidence of postoperative pulmonary complications in this cohort. On multivariate analysis, the volume of lung spared from doses {>=}5 Gy (VS5) was the only significant independent factor associated with postoperative pulmonary complications (p = 0.005). Conclusions: Dosimetric factors but not clinical factors were found to be strongly associated with the incidence of postoperative pulmonary complications in this cohort of esophageal cancer patients treated with concurrent chemoradiation plus surgery. The volume of the lung spared from doses of {>=}5 Gy was the only independent dosimetric factor in multivariate analysis. This suggests that ensuring an adequate volume of lung unexposed to radiation might reduce the incidence of postoperative pulmonary complications.
