Laparoscopic Surgery for Rectal Cancer  

PubMed Central

Laparoscopic surgery for rectal cancer is much more challenging than that for colon cancer because of the confined space within the pelvis. Further, because of the tumor's location in the pelvis, maintenance of resection margins is of greater concern. Nonrandomized studies by groups experienced in laparoscopic surgery have shown both that it produces short-term outcomes equivalent to those for open surgery and that it can be performed safely from an oncologic perspective. Nonsurgical complications appear to be fewer, but conversion to open surgery may become a real issue. This review summarizes these findings by addressing technical considerations, early outcomes, late outcomes, costs, and complications. PMID:21373245

Robotic Surgery for Oropharyngeal Cancer  

PubMed Central

Oropharyngeal cancer represents a growing proportion of head and neck malignancies. This has been associated with the increase in infection of the oropharynx by oncogenic strains of human papillomavirus (HPV). Transoral robotic surgery (TORS) has opened the door for minimally invasive surgery for HPV-related and non-HPV-related oropharyngeal cancer. Compared to traditional open surgical approaches, TORS has been shown to improve functional outcomes in speech and swallowing, while maintaining good oncologic outcomes. PMID:24808952

[Robotic surgery for cancer treatment].  

PubMed

Surgical operation is still one of the important options for treatment of many types of cancer. In the present-day treatment of cancer, patients' quality of life is focused on and surgeons need to provide minimally invasive surgery without decreasing the curability of disease. Endoscopic surgery contributed to the prevalence of minimally -invasive surgery. However it has also raised a problem regarding differences in surgical techniques among individual surgeons. Robot-assisted surgery provides some resolutions with 3D vision and increases the freedom of forceps manipulation. Furthermore, 3D visual magnification, scaling function, and the filtering function of surgical robots may make it possible for surgeons to perform microsurgery more delicate than open surgery. Here, we report the present status and the future of the representative surgical robot, and the da Vinci surgical system. PMID:22241345

Intraoperative Imaging-Guided Cancer Surgery: From Current Fluorescence Molecular Imaging Methods to Future Multi-Modality Imaging Technology  

PubMed Central

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.

Cancer Surgery in the Elderly  

PubMed Central

The proportions both of elderly patients in the world and of elderly patients with cancer are both increasing. In the evaluation of these patients, physiologic age, and not chronologic age, should be carefully considered in the decision-making process prior to both cancer screening and cancer treatment in an effort to avoid ageism. Many tools exist to help the practitioner determine the physiologic age of the patient, which allows for more appropriate and more individualized risk stratification, both in the pre- and postoperative periods as patients are evaluated for surgical treatments and monitored for surgical complications, respectively. During and after operations in the oncogeriatric populations, physiologic changes occuring that accompany aging include impaired stress response, increased senescence, and decreased immunity, all three of which impact the risk/benefit ratio associated with cancer surgery in the elderly.

Patients’ Refusal of Surgery Strongly Impairs Breast Cancer Survival  

PubMed Central

Objective: To compare patient and tumor characteristics and survival between women who refused and women who accepted surgery for breast cancer. Summary Background Data: Surgery represents the central component of curative breast cancer treatment, but some women decide not to undergo surgery. Recent studies on the prognosis of non operated breast cancer are nonexistent. Patients and Methods: This study included all 5339 patients aged < 80 years with nonmetastatic breast cancer recorded at the Geneva Cancer Registry between 1975 and 2000. We consulted the clinical files of all nonoperated women to identify those who refused surgery. Patients who refused surgery were compared with those accepting surgery using logistic regression. The effect of refusal of surgery on breast cancer mortality was evaluated by Cox proportional hazards analysis. Results: Seventy patients (1.3%) refused surgery. These women were older, more frequently single, and had larger tumors. Overall, 37 (53%) women had no treatment, 25 (36%) hormone-therapy alone, and 8 (11%) other adjuvant treatments alone or in combination. Five-year specific breast cancer survival of women who refused surgery was lower than that of those who accepted (72%, 95% confidence interval, 60%–84% versus 87%, 95% confidence interval, 86%–88%, respectively). After accounting for other prognostic factors including tumor characteristics and stage, women who refused surgery had a 2.1-fold (95% confidence interval, 1.5–3.1) increased risk to die of breast cancer compared with operated women. Conclusions: Women who refuse surgery for breast cancer have a strongly impaired survival. This information might help patients who are hesitant toward surgery make a better informed decision.

Surgery beats chemotherapy for tongue cancer  

Cancer.gov

Patients with tongue cancer who started their treatment with a course of chemotherapy fared significantly worse than patients who received surgery first, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center. This is contrary to protocols for larynx cancer, in which a single dose of chemotherapy helps determine which patients fare better with chemotherapy and radiation and which patients should elect for surgery. In larynx cancer, this approach, which was pioneered and extensively researched at U-M, has led to better patient survival and functional outcomes. But this new study, which appears in JAMA Otolaryngology Head and Neck Surgery, describes a clear failure.

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

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.

Sentinel node navigation surgery for gastric cancer: Overview and perspective  

PubMed Central

The sentinel node (SN) technique has been established for the treatment of some types of solid cancers to avoid unnecessary lymphadenectomy. If node disease were diagnosed before surgery, minimal surgery with omission of lymph node dissection would be an option for patients with early gastric cancer. Although SN biopsy has been well ascertained in the treatment of breast cancer and melanoma, SN navigation surgery (SNNS) in gastric cancer has not been yet universal due to the complicated lymphatic flow from the stomach. Satisfactory establishment of SNNS will result in the possible indication of minimally invasive surgery of gastric cancer. However, the results reported in the literature on SN biopsy in gastric cancer are widely divergent and many issues are still to be resolved, such as the collection method of SN, detection of micrometastasis in SN, and clinical benefit. The difference in the procedural technique and learning phase of surgeons is also varied the accuracy of SN mapping. In this review, we outline the current status of application for SNNS in gastric cancer. PMID:25625004

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

Surgery for nonsmall cell lung cancer.  

PubMed

Surgery remains the best curative option in patients with early stage lung cancer (stage I and II). Developments in minimally invasive techniques now allow surgeons to perform lung resections on elderly patients, patients with poor pulmonary function or significant cardiopulmonary comorbidities. New techniques, such as stereotactic radiotherapy and ablative procedures, are being evaluated in early-stage lung cancer and may represent an alternative to surgery in patients unfit for lung resection. Perioperative mortality rates have dropped significantly at most institutions in the past two decades and complications are managed more efficiently. Progress in imaging and staging techniques have helped cut futile thoracotomy rates and offer patients the most adequate treatment options. Large randomised trials have helped clarify the role of neoadjuvant, induction and adjuvant chemotherapy, as well as radiotherapy. Surgery remains an essential step in the multimodality therapy of selected patients with advanced-stage lung cancer (stage III and IV). Interventional and endoscopic techniques have reduced the role of surgery in the diagnosis and staging of nonsmall cell lung cancer, but surgery remains an important tool in the palliation of advanced-stage lung cancer. Large national/international surgical databases have been developed and predictive risk-models for surgical mortality/morbidity published by learned surgical societies. Nonetheless, lung cancer overall survival rates remain deceptively low and it is hoped that early detection/screening, better understanding of tumour biology and development of biomarkers, and development of efficient targeted therapies will help improve the prognosis of lung cancer patients in the next decade.

Blood transfusion practices in cancer surgery  

PubMed Central

Cancer patients are commonly transfused with blood products immediately before, during or after major surgery. Blood loss and haemodilution are the most common causes of red blood cells (RBCs) administration and coagulopathies are the indications for the infusion of fresh-frozen plasma (FFP), cryoprecipitates and platelets. Transfusion-related immune modulation is a complication associated with the administration of blood products. A decreased immune surveillance as a consequence of blood transfusions has been linked to cancer recurrence and progression. Moreover, soluble factors present in packed RBCs, platelets and FFP can directly stimulate tumour growth and spread. Two meta-analyses suggest that the administration of blood products is associated with shorter recurrence-free survival and overall survival after colorectal cancer surgery. More studies are needed to show such association in different cancer patient populations.

Impact of conversion on outcome in laparoscopic colorectal cancer surgery  

PubMed Central

Introduction Long-term results after laparoscopic surgery with conversion to open surgery for colorectal cancer are seldom published. Aim The study analysed the impact of conversion of laparoscopic surgery to open resection for colorectal cancer on short- and long-term results. Material and methods The prospectively collected data of 469 patients with colorectal cancer in the period from 1 January 2001 to 31 December 2006 were analysed. Short- and long-term results were compared. Results The relative frequency of conversion was 7%. The subgroups were statistically similar regarding age, gender, body mass index (BMI), localization of tumour, T stage, and TNM stage. We observed a lower frequency of previous surgery (p = 0.018) in the group of patients with conversions to open surgery as well as statistically significantly higher frequency of patients with American Society of Anesthesiologists (ASA) score II (p = 0.039). There was no statistical difference in morbidity, mortality, or the length of hospital stay between both the groups of patients. The operating time was significantly higher in the group of patients with conversion (p = 0.00001). There was a significantly higher blood loss in the patient groups with conversion to open surgery and in the group with primarily open surgery (p = 0.00023). There was no difference in the overall survival (p = 0.712), disease-free survival (p = 0.072) or in the local (p = 0.432) or distant (p = 0.957) recurrence. Conclusions No negative impact on short- or long-term results of conversion to open surgery was verified in patients with colorectal surgery. PMID:23256006

Breast-conserving surgery in breast cancer.  

PubMed

The breast cancer treatment is based nowadays on new surgical options: breast-conserving surgery, which applies at least for the first and second stage cancer, with radical intention. We have been practicing breast-conserving surgery for the last 16 years and we have performed 303 breast conserving operations from a total of 673. We recorded 12 local recurrences (3,96%) and 2 deaths due to cancer progression. Our protocol includes removal of the primary tumor with enough surrounding tissue to ensure negative margins of the resectable specimen, associated with axillary lymph-node dissection and postoperative breast irradiation. Our oncologist indicated chemotherapy on different postoperative conditions: tumor size, axillary lymph node involvement, patient's age, etc. The purpose of this paper is to emphasize our modest experience, nevertheless to draw the attention on important results, obtained by long-term monitoring of the patients who underwent breast-conserving surgery, in a two prospective protocols, and demonstrate the importance and applicability of breast conserving therapy. The conclusion of this study is that breast-conserving surgery followed by breast irradiation is reliable, as the results are similar with radical mastectomies; the main objective is to obtain a good cosmetic result, which depends on tumor size / breast size.

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.

Robotic Surgery for Cervical Cancer  

PubMed Central

The development of robotic technology has facilitated the application of minimally invasive techniques for the treatment and evaluation of patients with early, advanced, and recurrent cervical cancer. The application of robotic technology for selected patients with cervical cancer and the data available in the literature are addressed in the present review paper. The robotic radical hysterectomy technique developed at the Mayo Clinic Arizona is presented with data comparing 27 patients who underwent the robotic procedure with 2 matched groups of patients treated by laparoscopic (N = 31), and laparotomic radical hysterectomy (N = 35). A few other studies confirmed the feasibility and safety of robotic radical hysterectomy and comparisons to either to the laparoscopic or open approach were discussed. Based on data from the literature, minimally invasive techniques including laparoscopy and robotics are preferable to laparotomy for patients requiring radical hysterectomy, with some advantages noted for robotics over laparoscopy. A prospective randomised trial is currently being perfomred under the auspices of the American Association of Gyneoclogic Laparoscopists comparing minimally invasive radical hysterectomy (laparoscopy or robotics) with laparotomy. For early cervical cancer radical parametrectomy and fertility preserving trachelectomy have been performed using robotic technology and been shown to be feasible, safe, and easier to perform when compared to the laparoscopic approach. Similar benefits have been noted in the treatment of advanced and recurrent cervical cancer where complex procedures such as extraperitoneal paraortic lymphadenectomy and pelvic exenteration have been required. Conclusion: Robotic technology better facilitates the surgical approach as compared to laparoscopy for technically challenging operations performed to treat primary, early or advanced, and recurrent cervical cancer. Although patient advantages are similar or slightly improved with robotics, there are multiple advantages for surgeons. PMID:19108008

During the last decade the role of minimally invasive surgery has been increased, especially with the introduction of the robotic system in the surgical field. The most important advantages of robotic system are represented by the wristed instrumentation and the depth perception, which can overcome the limitation of traditional thoracoscopy. However, some data still exist in literature with regard to robotic lobectomy. The majority of papers are focused on its safety and feasibility, but further studies with long follow-ups are necessary in order to assess the oncologic outcomes. We reviewed the literature on robotic lobectomy, with the main aim to better define the role of robotic system in the clinical practice. PMID:25207216

Operative Risk Factors in Gastric Cancer Surgery for Elderly Patients  

PubMed Central

Purpose Gastric cancer surgery is a common operation in East Asia, such as Korea and Japan, and there has been a significant increase in the need for this procedure due to the aging population. As a result, surgery for the treatment of gastric cancer for elderly patients is expected to increase. This study examined the effect of old age on gastric cancer surgery, and analyzed the operative risk factors for elderly patients. Materials and Methods From November 2008 to August 2010, 590 patients, who underwent a curative resection for gastric cancers, were enrolled. Patients who underwent palliative or emergency surgery were excluded. A retrospective analysis of the correlation between surgical outcomes and age was performed. The elderly were defined as patients who were over the age of 65 years. Results The mean age of all patients was 58.3 years, and complications occurred in 87 cases (14.7%). The most common complication was wound infection and severe complications requiring surgical, endoscopic, or radiologic intervention developed in 52 cases (8.8%). The rate of complications increased with increasing age of the patients. Univariate analysis revealed age, comorbidity, extent of resection, operation time, and combined resection to be associated with surgical complications. In particular, age over 75 years old, operation time, and comorbidity were predictive factors in multivariate analysis. In the elderly, only comorbidity was associated with surgical complications. Conclusions The patients' age is the most important factor for predicting surgical complications. Surgeons should pay an attention to the performance of gastric cancer surgery on elderly patients. In particular, it must be performed carefully for elderly patients with a comorbidity. PMID:22076212

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

Laparoscopic surgery for colorectal cancer in China: an overview  

PubMed Central

Since its introduction into China in 2001, laparoscopic techniques have been extensively used for the surgical management of colorectal cancer during the last two decades in China. Like all the pioneers of the technique, Chinese gastrointestinal surgeons claim that laparoscopic surgery for colorectal cancer led to faster recovery, shorter hospital stay and more rapid return to daily activities respect to open surgery while offering the same functional and oncological results. There has been booming interest in laparoscopic surgery for colorectal cancer since 2006 in China. The last decade has witnessed national growth in the application of laparoscopic surgery for colorectal cancer and yielded a significant amount of scientific data to support its clinical merits and advantages. However, few prospective randomized controlled trials have investigated the benefits of laparoscopic surgery for colorectal cancer in China. In this article, we make an overview of the current data and state of the art of laparoscopic surgery for colorectal cancer in China. PMID:25663960

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

Minimally Invasive Surgery for Colorectal Cancer: Past, Present, and Future  

PubMed Central

A rapid progression from conventional open surgery to minimally invasive approaches in the surgical management of colorectal cancer has occurred over the last 2 decades. Initial concerns that this new approach was oncologically inferior to open surgery were ultimately refuted when several prospective randomized trials concluded that laparoscopic colectomy could achieve similar oncologic outcomes to open surgery. On the contrary, level 1 data has not yet matured regarding the oncologic safety of minimally invasive approaches for rectal cancer. We review the published literature pertaining to the evolution of minimally invasive techniques used to treat colorectal cancer surgery, including barriers to adoption, and the prospects for future advances related to innovative techniques.

Body Image Screening for Cancer Patients Undergoing Reconstructive Surgery  

PubMed Central

Objectives Body image is a critical issue for cancer patients undergoing reconstructive surgery, as they can experience disfigurement and functional impairment. Distress related to appearance changes can lead to various psychosocial difficulties, and patients are often reluctant to discuss these issues with their healthcare team. Our goals were to design and evaluate a screening tool to aid providers in identifying patients who may benefit from referral for specialized psychosocial care to treat body image concerns. Methods We designed a brief 4-item instrument and administered it at a single time point to cancer patients who were undergoing reconstructive treatment. We used simple and multinomial regression models to evaluate whether survey responses, demographic, or clinical variables predicted interest and enrollment in counseling. Results Over 95% of the sample (n = 248) endorsed some concerns, preoccupation, or avoidance due to appearance changes. Approximately one-third of patients were interested in obtaining counseling or additional information to assist with body image distress. Each survey item significantly predicted interest and enrollment in counseling. Concern about future appearance changes was the single best predictor of counseling enrollment. Sex, age, and cancer type were not predictive of counseling interest or enrollment. Conclusions We present initial data supporting use of the Body Image Screener for Cancer Reconstruction. Our findings suggest benefits of administering this tool to patients presenting for reconstructive surgery. It is argued that screening and treatment for body image distress should be provided to this patient population at the earliest possible time point. PMID:25066586

Despite optimal treatment (complete cytoreduction and adjuvant chemotherapy), 5-year survival for advanced ovarian cancer is approximately 30% and most patients succumb to their disease. Cytoreductive surgery is accepted as a major treatment of primary ovarian cancer but its role in recurrent disease is controversial and remains a field of discussion mainly owing to missing data from prospective randomized trials. A critical review of literature evidence on secondary surgery in recurrent ovarian cancer will be described. PMID:22919475

Laparoscopic versus Open Surgery for Colorectal Cancer: A Retrospective Analysis of 163 Patients in a Single Institution  

PubMed Central

Background. The present study aimed to compare the clinical outcomes of laparoscopic versus open surgery for colorectal cancers. Materials and Methods. The medical records from a total of 163 patients who underwent surgery for colorectal cancers were retrospectively analyzed. Patient's demographic data, operative details and postoperative early outcomes, outpatient follow-up, pathologic results, and stages of the cancer were reviewed from the database. Results. The patients who underwent laparoscopic surgery showed significant advantages due to the minimally invasive nature of the surgery compared with those who underwent open surgery, namely, less blood loss, faster postoperative recovery, and shorter postoperative hospital stay (P < 0.05). However, laparoscopic surgery for colorectal cancer resulted in a longer operative time compared with open surgery (P < 0.05). There were no statistically significant differences between groups for medical complications (P > 0.05). Open surgery resulted in more incisional infections and postoperative ileus compared with laparoscopic surgery (P < 0.05). There were no differences in the pathologic parameters between two groups (P < 0.05). Conclusions. These findings indicated that laparoscopic surgery for colorectal cancer had the clear advantages of a minimally invasive surgery and relative disadvantage with longer surgery time and exhibited similar pathologic parameters compared with open surgery.

Current status of function-preserving surgery for gastric cancer  

PubMed Central

Recent advances in diagnostic techniques have allowed the diagnosis of gastric cancer (GC) at an early stage. Due to the low incidence of lymph node metastasis and favorable prognosis in early GC, function-preserving surgery which improves postoperative quality of life may be possible. Pylorus-preserving gastrectomy (PPG) is one such function-preserving procedure, which is expected to offer advantages with regards to dumping syndrome, bile reflux gastritis, and the frequency of flatus, although PPG may induce delayed gastric emptying. Proximal gastrectomy (PG) is another function-preserving procedure, which is thought to be advantageous in terms of decreased duodenogastric reflux and good food reservoir function in the remnant stomach, although the incidence of heartburn or gastric fullness associated with this procedure is high. However, these disadvantages may be overcome by the reconstruction method used. The other important problem after PG is remnant GC, which was reported to occur in approximately 5% of patients. Therefore, the reconstruction technique used with PG should facilitate postoperative endoscopic examinations for early detection and treatment of remnant gastric carcinoma. Oncologic safety seems to be assured in both procedures, if the preoperative diagnosis is accurate. Patient selection should be carefully considered. Although many retrospective studies have demonstrated the utility of function-preserving surgery, no consensus on whether to adopt function-preserving surgery as the standard of care has been reached. Further prospective randomized controlled trials are necessary to evaluate survival and postoperative quality of life associated with function-preserving surgery. PMID:25516640

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

Patient factors may predict anastomotic complications after rectal cancer surgery  

PubMed Central

Purpose Anastomotic complications following rectal cancer surgery occur with varying frequency. Preoperative radiation, BMI, and low anastomoses have been implicated as predictors in previous studies, but their definitive role is still under review. The objective of our study was to identify patient and operative factors that may be predictive of anastomotic complications. Methods A retrospective review was performed on patients who had sphincter-preservation surgery performed for rectal cancer at a tertiary medical center between 2005 and 2011. Results 123 patients were included in this study, mean age was 59 (26–86), 58% were male. There were 33 complications in 32 patients (27%). Stenosis was the most frequent complication (24 of 33). 11 patients required mechanical dilatation, and 4 had operative revision of the anastomosis. Leak or pelvic abscess were present in 9 patients (7.3%); 4 were explored, 2 were drained and 3 were managed conservatively. 4 patients had permanent colostomy created due to anastomotic complications. Laparoscopy approach, BMI, age, smoking and tumor distance from anal verge were not significantly associated with anastomotic complications. After a multivariate analysis chemoradiation was significantly associated with overall anastomotic complications (Wall = 0.35, p = 0.05), and hemoglobin levels were associated with anastomotic leak (Wald = 4.09, p = 0.04). Conclusion Our study identifies preoperative anemia as possible risk factor for anastomotic leak and neoadjuvant chemoradiation may lead to increased risk of complications overall. Further prospective studies will help to elucidate these findings as well as identify amenable factors that may decrease risk of anastomotic complications after rectal cancer surgery.

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

The quality of research synthesis in surgery: the case of laparoscopic surgery for colorectal cancer  

PubMed Central

Background Several systematic reviews and meta-analyses populate the literature on the effectiveness of laparoscopic surgery for colorectal cancer. The utility of this body of work is unclear. The objective of this study was to synthesize all such systematic reviews in terms of clinical effectiveness, to appraise their quality, and to determine whether areas of duplication exist across reviews. Methods Systematic reviews comparing laparoscopic and open surgery for colorectal cancer were identified using a comprehensive search protocol (1991 to 2008). The primary outcome was overall survival. The methodological quality of reviews was appraised using the Assessment of Multiple Systematic Reviews (AMSTAR) instrument. Abstraction and quality appraisal was carried out by two independent reviewers. Reviews were synthesized, and outcomes were compared qualitatively. A citation analysis was carried out using simple matrices to assess the comprehensiveness of each review. Results In total, 27 reviews were included; 13 reviews included only randomized controlled trials. Rectal cancer was addressed exclusively by four reviews. There was significant overlap between review purposes, populations and, outcomes. The mean AMSTAR score (out of 11) was 5.8 (95% CI: 4.6 to 7.0). Overall survival was evaluated by ten reviews, none of which found a significant difference. Three reviews provided a selective meta-analysis of time-to-event data. Previously published systematic reviews were poorly and highly selectively referenced (mean citation ratio 0.16, 95% CI: 0.093 to 0.22). Previously published trials were not comprehensively identified and cited (mean citation ratio 0.56, 95% CI: 0.46 to 0.65). Conclusions Numerous overlapping systematic reviews of laparoscopic and open surgery for colorectal cancer exist in the literature. Despite variable methods and quality, survival outcomes are congruent across reviews. A duplication of research efforts appears to exist in the literature. Further systematic reviews or meta-analyses are unlikely to be justified without specifying a significantly different research objective. This works lends support to the registration and updating of systematic reviews. PMID:22588035

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.

Extrahepatic Bile Duct Cancers: Surgery Alone Versus Surgery Plus Postoperative Radiation Therapy  

SciTech Connect

Purpose: The goal of this study was to determine the role of radiotherapy after curative-intent surgery in the management of extrahepatic bile duct (EHBD) cancers. Methods and Materials: From 1997 through 2005, 78 patients with EHBD cancer were surgically staged. These patients were stratified by the absence of adjuvant radiation (n = 47, group I) versus radiation (n = 31, group II) after resection. Pathology examination showed 27 cases in group I and 20 cases in group II had microscopically positive resection margins. The patients in group II received 45 to 54 Gy of external beam radiotherapy. The primary endpoints of this study were overall survival, disease-free survival, and prognostic factors. Results: There were no differences between the 5-year overall survival rates for the two groups (11.6% in group I vs. 21% in group II). However, the patients with microscopically positive resection margins who received adjuvant radiation therapy had higher median disease-free survival rates than those who underwent surgery alone (21 months vs. 10 months, respectively, p = 0.042). Decreasing local failure was found in patients who received postoperative radiotherapy (61.7% in group I and 35.6% in group II, p = 0.02). Outcomes of the patients with a positive resection margin and lymph node metastasis who received postoperative radiation therapy were doubled compared to those of patients without adjuvant radiotherapy. Resection margin status, lymph node metastasis, and pathology differentiation were significant prognostic factors in disease-free survival. Conclusions: Adjuvant radiotherapy might be useful in patients with EHBD cancer, especially for those patients with microscopic residual tumors and positive lymph nodes after resection for increasing local control.

Simultaneous resection of colorectal cancer and liver metastases in the right lobe using pure laparoscopic surgery.  

PubMed

It is now common to resect colorectal cancer by laparoscopic surgery. Hepatectomy has become a standard treatment for patients with colorectal cancer with resectable liver metastases. The resection of liver tumors can now be done partly by laparoscopic surgery. However, metastatic tumors in the right lobe are often difficult to resect laparoscopically. Furthermore, simultaneous resection of the colorectum and liver may also be difficult. In this study, we evaluated a new method to resect both colorectal cancer and liver metastases in the right lobe by laparoscopic surgery. Two cases are presented that underwent total laparoscopic resection of a right lobe tumor, associated with laparoscopic colorectal resection. The metastatic tumor in the right lobe was first resected in the left hemi-prone position. Then, the colorectal cancer was resected in the lithotomy position. The method for resecting the right lobe liver tumor and colorectal cancer was safe and feasible. The mean duration of surgery was 443.5 min, and the mean blood loss was 158 mL. The postoperative course was uneventful. In selected patients, laparoscopic hepatectomy for right lobe synchronous metastatic tumors can be safely performed simultaneously with colorectal surgery.

Is there any evidence of a “July effect” in patients undergoing major cancer surgery?  

PubMed Central

Background The “July effect” refers to the phenomenon of adverse impacts on patient care arising from the changeover in medical staff that takes place during this month at academic medical centres in North America. There has been some evidence supporting the presence of the July effect, including data from surgical specialties. Uniformity of care, regardless of time of year, is required for patients undergoing major cancer surgery. We therefore sought to perform a population-level assessment for the presence of a July effect in this field. Methods We used the Nationwide Inpatient Sample to abstract data on patients undergoing 1 of 8 major cancer surgeries at academic medical centres between Jan. 1, 1999, and Dec. 30, 2009. The primary outcomes examined were postoperative complications and in-hospital mortality. Univariate analyses and subsequently multivariate analyses, controlling for patient and hospital characteristics, were performed to identify whether the time of surgery was an independent predictor of outcome after major cancer surgery. Results On univariate analysis, the overall postoperative complication rate, as well as genitourinary and hematologic complications specifically, was higher in July than the rest of the year. However, on multivariate analysis, only hematologic complications were significantly higher in July, with no difference in overall postoperative complication rate or in-hospital mortality for all 8 surgeries considered separately or together. Conclusion On the whole, the data confirm an absence of a July effect in patients undergoing major cancer surgery. PMID:24666444

Is open surgery for head and neck cancers truly declining?  

PubMed

In the past two decades, major modifications in the way we treat head and neck cancers, due to advances in technology and medical oncology, have led to a decline in the use of open surgery as first-line treatment of cancers arising from several primary tumor sites. The incidence of tobacco- and alcohol-related squamous cell carcinoma of the pharynx and larynx has been steadily decreasing, with a rise in the incidence of human papillomavirus-related oropharyngeal tumors and the use of minimally invasive endoscopic surgery and non-surgical treatment modalities has increased in the treatment of all of these tumors. However, open surgery remains the initial definitive treatment modality for other tumors, including tumors of the skin, oral cavity, sinonasal cavities and skull base, salivary glands, thyroid and sarcomas. Selected group of nasal, paranasal, base of the skull and thyroid tumors are also candidates for minimally invasive procedures. For some indications, the rate of open surgery has actually increased in the past decade, with an increase in the incidence of oral cavity, thyroid and skin cancer, an increase in the number of neck dissections performed, and an increase in salvage surgery and free flap reconstruction. The use of minimally invasive, technology-based surgery-with the use of lasers, operating microscopes, endoscopes, robots and image guidance-has increased. Technology, epidemiology and advances in other domains such as tissue engineering and allotransplantations may further change the domains of competencies for future head and neck surgeons.

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

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.

Long-term survival after endoscopic resection for early gastric cancer in the remnant stomach: comparison with radical surgery  

PubMed Central

Background Endoscopic resection (ER) has recently become standard treatment, even for early gastric cancer (EGC) in the remnant stomach. We aimed to compare long-term survival after ER versus radical surgery for EGC in the remnant stomach. Methods We retrospectively compared overall and cause-specific survival of patients who had undergone ER or radical surgery for EGC in the remnant stomach from 1998 to 2012. Results During the study period, 32 patients with intramucosal (M), two with shallow submucosal (SM1) and eight with deep submucosal (SM2) cancers had undergone ER (ER group) whereas six with M and seven with SM2 cancers had undergone surgery (surgery group). All patients were followed up for a median of 60 months; during follow up, 15 patients died, including three in the ER group with SM2 cancer who died of gastric cancer. The overall 5-year survival rates of M-SM1 and SM2 cancer patients in the ER and surgery groups were 89%, 48%, 80%, and 67%, respectively (P=0.079). The disease-specific 5-year survival rates of M-SM1 and SM2 cancer patients in the ER and surgery groups were 100%, 48%, 100%, and 100%, respectively (P=0.000). Operation time and hospital stay were significantly shorter in the ER than the surgery group (P<0.001). Grade 2 perforation occurred in two patients in the ER group and Grade 3 anastomotic leakage in two patients in the surgery group. Conclusion ER provides excellent outcomes, comparable with those of radical surgery, in patients with M-SM1 gastric cancer in the remnant stomach; however, patients with SM2 cancer require radical surgery.

Novel training methods for robotic surgery  

PubMed Central

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

Role of surgery in ovarian cancer: an update.  

PubMed

Rupture of an ovarian malignant tumor should be avoided at the time of surgery for an early ovarian cancer. Laparoscopic removal of ovarian cysts should be restricted to patients with preoperative evidence that the cyst is benign. Degree of differentiation is the most important independent prognostic factor in stage I disease and should be used in decisions on therapy in clinical practice and the future FIGO-classification of Stage I. In early ovarian cancer staging adequacy and tumor grade were the only 2 statistical significant prognostic factors for survival in the multivariate analysis of the EORTC ACTION-trial. According to the present data there is no scientific basis to rely only on adjuvant chemotherapy or on optimal staging procedure in medium and high risk stage I ovarian cancer. Primary debulking surgery by a gynecologic oncologist remains the standard of care in advanced ovarian cancer. Optimal debulking surgery should be defined as no residual tumor load. Interval debulking is defined as an operation performed after a short course of induction chemotherapy, usually 2 or 3 cycles. Based on the randomized EORTC-GCG trial, interval debulking by an experienced surgeon improves survival in some patients who did not undergo optimal primary debulking surgery. Based on the GOG 152 data, interval debulking surgery does not seem to be indicated in patients who underwent primarily a maximal surgical effort by a gynecological oncologist. Open laparoscopy is probably the most valuable tool for evaluating the operability primarily or at the time of interval debulking surgery. In retrospective analyses neoadjuvant chemotherapy followed by interval debulking surgery does not seem to worsen prognosis compared to primary debulking surgery followed by chemotherapy. However, we will have to wait for the results of the EORTC-GCG/NCI Canada randomized trial to know whether neoadjuvant chemotherapy followed by interval debulking surgery is as good as primary debulking surgery in some or all stage IIIc and IV patients. The most suitable candidates for secondary debulking surgery are those who had an initial complete response to chemotherapy, a long treatment-free interval (e.g. more than 12 months), and resectable disease (without diffuse carcinomatosis).

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

Definition of Compartment Based Radical Surgery in Uterine Cancer—Part I: Therapeutic Pelvic and Periaortic Lymphadenectomy by Michael Höckel 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

A Comparative Study of Single-Port Laparoscopic Surgery Versus Robotic-Assisted Laparoscopic Surgery for Rectal Cancer.  

PubMed

Introduction. Conventional laparoscopic surgery is the treatment of choice for many abdominal procedures. To further reduce surgical trauma, new minimal invasive procedures such as single-port laparoscopic surgery (SPLS) and robotic assisted laparoscopic surgery (RALS) have emerged. The aim of this study was to compare the early results of SPLS versus RALS in the treatment of rectal cancer. Methods. We performed a retrospective analysis of prospectively collected data on patients who had undergone SPLS (n = 36) or RALS (n = 56) in the period between 2010 and 2012. Operative and short-term oncological outcomes were compared. Results. The RALS group had fewer patients with low rectal cancer and more patients with mid-rectal tumors (P = .017) and also a higher rate of intraoperative complications (14.3% vs 0%, P = .021). The rate of postoperative complications did not differ (P = .62). There were no differences in circumferential resection margins, distal resection margins, or completeness of the mesorectal fascia. The RALS group had a larger number of median harvested lymph nodes (27 vs 13, P = .001). The SPLS group had fewer late complications (P = .025). There were no locoregional recurrences in either of the groups. There was no difference in median follow-up time between groups (P = .58). Conclusion. Both SPLS and RALS may have a role in rectal surgery. The short-term oncological outcomes were similar, although RALS harvested more lymph nodes than the SPLS procedure. However, SPLS seems to be safer with regard to intraoperative and late postoperative complications. PMID:25377216

Hoarseness caused by arytenoid dislocation after surgery for lung cancer.  

PubMed

The patient was a 64-year-old woman with no history of laryngeal disorders. She underwent video-assisted right lower lobectomy and node dissection for lung cancer. Using a stylet while the patient was under general anesthesia, tracheal intubation with a 35-French gauge left-sided double-lumen endobronchial tube was successfully performed on the first attempt. The patient developed slight hoarseness on postoperative day 1, and we initially suspected recurrent laryngeal nerve paralysis caused by the surgery, which we elected to treat conservatively. However, because her hoarseness had not improved 4 months after surgery, we evaluated her vocal cords using laryngoscopy. This revealed severe dysfunction of the right vocal cord and arytenoid dislocation, which we treated through reduction using a balloon catheter. By 6 months, the patient's vocal cord mobility had improved. Arytenoid dislocation is a rare complication, but should be suspected when patients have right vocal fold paralysis after lung cancer surgery. PMID:23807399

The history of lymphadenectomy for esophageal cancer and the future prospects for esophageal cancer surgery.  

PubMed

I would herein like to look back upon surgery for esophageal cancer, particularly on lymphadenectomy, and to speculate a little on the future prospects for esophageal surgery. There are two schools of thought on lymphadenectomy in esophageal cancer: one believes in en bloc esophagectomy, which is commonly performed in Western countries; the other believes in three-field lymphadenectomy, which is commonly performed in Japan. We esophageal surgeons at Kurume University have contributed to some advances in three-field lymphadenectomy. For example, we initiated functional mediastinal dissection to ensure patient safety, and we proposed the lymph node compartment theory to assess the clinical importance of regional nodes. Oncological surgery has progressed in terms of its safety, radicality and functional preservation, leading to improved quality-of-life for patients after surgery. This then evolved to the current development of multimodal and individualized tailor-made treatments. I believe that surgery for esophageal cancer will become bipolarized in the future. One strand will evolve as salvage surgery for residual or recurrent tumors, which non-surgical therapies have failed to cure, and the other strand will evolve as less invasive surgery, adjuvant surgery, for cancers at the relatively early stage, for which micro-metastasis can be cured by non-surgical therapies.

Analgesic and Antiemetic Requirements After Minimally Invasive Surgery for Early Cervical Cancer: A Comparison Between Laparoscopy and Robotic Surgery  

PubMed Central

Background Women with early cervical cancer undergoing radical hysterectomy via minimally invasive surgery (MIS) have decreased blood loss and a shorter hospital stay compared with laparotomy. It remains unclear whether there is a difference in benefit to the patient between robotic surgery and traditional laparoscopy. We sought to compare postoperative analgesic and antiemetic requirements between the two approaches. Methods After institutional review board approval, the medication administration records of all patients who underwent MIS radical hysterectomy for cervical cancer at MD Anderson Cancer Center were reviewed. Analgesic and antiemetic medication use as well as visual pain scores was recorded. Descriptive statistics and nonparametric tests were used to compare the groups undergoing laparoscopy (LRH) and robotic surgery (RRH). Result A total of 85 patients underwent MIS for early cervical cancer, 55 LRH and 30 RRH. Median age was older in the RRH (42 vs. 52 years, p = 0.001). There was no difference in median body mass index (26.9 vs. 26.8 kg/ m2, p = 0.71). Length of stay was significantly shorter in the RRH (2 vs. 1 day, p = 0.005). Total intravenous opioids administered were significantly higher in the LRH (26.7 mg morphine equivalents) compared with the RRH (10.7 mg morphine equivalents) (p = 0.001). There was no difference in visual pain scores or antiemetics given. Conclusions Intravenous opioids administered were significantly less for RRH compared to LRH; however, there was no difference in visual pain scores. Prospective studies are being performed to evaluate quality of life in patients undergoing MIS for gynecologic cancers. PMID:23054117

Radiotherapy and chemoradiation after surgery for early cervical cancer  

PubMed Central

Background This is an updated version of the original Cochrane review first published in Issue 4, 2009. There is an ongoing debate about the indications for, and value of, adjuvant pelvic radiotherapy after radical surgery in women with early cervical cancer. Certain combinations of pathological risk factors are thought to represent sufficient risk for recurrence, that they justify the use of postoperative pelvic radiotherapy, though this has never been shown to improve overall survival, and use of more than one type of treatment (surgery and radiotherapy) increases the risks of side effects and complications. Objectives To evaluate the effectiveness and safety of adjuvant therapies (radiotherapy, chemotherapy followed by radiotherapy, chemoradiation) after radical hysterectomy for early-stage cervical cancer (FIGO stages IB1, IB2 or IIA). Search methods For the original review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 4, 2008. The Cochrane Gynaecological Cancer Group Trials Register, MEDLINE (January 1950 to November 2008), EMBASE (1950 to November 2008). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field. For this update, we extended the database searches to September 2011 and searched the MetaRegister for ongoing trials. Selection criteria Randomised controlled trials (RCTs) that compared adjuvant therapies (radiotherapy, chemotherapy followed by radiotherapy, or chemoradiation) with no radiotherapy or chemoradiation, in women with a confirmed histological diagnosis of early cervical cancer who had undergone radical hysterectomy and dissection of the pelvic lymph nodes. Data collection and analysis Two review authors independently abstracted data and assessed risk of bias. Information on grade 3 and 4 adverse events was collected from the trials. Results were pooled using random-effects meta-analyses. Main results Two RCTs, which compared adjuvant radiotherapy with no adjuvant radiotherapy, met the inclusion criteria; they randomised and assessed 397 women with stage IB cervical cancer. Meta-analysis of these two RCTs indicated no significant difference in survival at 5 years between women who received radiation and those who received no further treatment (risk ratio (RR) = 0.8; 95% confidence interval (CI) 0.3 to 2.4). However, women who received radiation had a significantly lower risk of disease progression at 5 years (RR 0.6; 95% CI 0.4 to 0.9). Although the risk of serious adverse events was consistently higher if women received radiotherapy rather than no further treatment, these increased risks were not statistically significant, probably because the rate of adverse events was low. Authors’ conclusions We found evidence, of moderate quality, that radiation decreases the risk of disease progression compared with no further treatment, but little evidence that it might improve overall survival, in stage IB cervical cancer. The evidence on serious adverse events was equivocal. PMID:22592722

Endoscopy-assisted breast-conserving surgery for breast cancer patients  

PubMed Central

Breast-conserving surgery (BCS) combined with postoperative radiotherapy is a standard therapy for early-stage breast cancer patients. In addition, recent developments in oncoplastic surgery have improved cosmetic outcomes and patient satisfaction. Therefore, a breast surgeon’s current role in BCS is not only to perform a curative resection of cancerous lesions with adequate surgical margins, but also to preserve the shape and appearance of the treated breast. Endoscopy-assisted breast-conserving surgery (EBCS), which has the advantage of a less noticeable scar, was developed more than ten years ago. Recently, some clinical studies have reported the feasibility, oncological outcomes, aesthetic outcomes, and patient satisfaction of EBCS. Herein, we will review the EBCS clinical studies that have been conducted so far and discuss current issues regarding this operative method. PMID:25083503

Three ports laparoscopic resection for colorectal cancer: a step on refining of reduced port surgery.  

PubMed

Background. Reduced port surgery (RPS) is becoming increasingly popular for some surgeries. However, the application of RPS to the field of colectomy is still underdeveloped. Patients and Methods. In this series, we evaluated the outcome of laparoscopic colorectal resection using 3 ports technique (10?mm umbilical port plus another two ports of either 5 or 10?mm) for twenty-four cases of colorectal cancer as a step for refining of RPS. Results. The mean estimated blood loss was 70?mL (40-90?mL). No major intraoperative complications have been encountered. The mean time for passing flatus after surgery was 36 hours (12-48?hrs). The mean time for oral fluid intake was 36 hours and for semisolid food was 48 hours. The mean hospital stay was 5 days (4-7 days). The perioperative period passed without events. All cases had free surgical margins. The mean number of retrieved lymph nodes was 14 lymph nodes (5-23). Conclusion. Three ports laparoscopy assisted colorectal surgeries looks to be safe, effective and has cosmetic advantages. The procedure could maintain the oncologic principles of cancer surgery. It's a step on the way of refining of reduced port surgery. PMID:25006515

Increasing Thyroid Cancer Rate and the Extent of Thyroid Surgery in Korea  

PubMed Central

Background It is evident that the rate of thyroid cancer is increasing throughout the world. One reason is increased detection of preclinical small cancers. However, it is not clear whether the increase in thyroid cancer rate is reducing the extent of thyroid surgeries. The purpose of this study was to evaluate the thyroid cancer rate and analyze recent changes in the extent of thyroid cancer surgeries in Korea. Methods An observational study was conducted using data from Korea’s Health Insurance Review and Assessment Service (HIRAS) for thyroidectomy with/without neck dissection, with 228,051 registered patients between 2007 and 2011. Data were categorized by the extent of surgery: unilateral thyroidectomy without neck dissection (UT), bilateral thyroidectomy or radical thyroidectomy without neck dissection (TT), any thyroidectomy with unilateral selective neck dissection (SND), any thyroidectomy with unilateral modified radical neck dissection (MRND), any thyroidectomy with unilateral radical neck dissection (RND), and any thyroidectomy with bilateral neck dissection (BND). Annual rate difference for each surgery was analyzed with a linear by linear association. Results The absolute numbers of total thyroid surgeries (UT+TT+SND+MRND+RND+BND) were increased from 28539 to 61481. The proportion of patients who underwent only thyroidectomy without neck dissection (UT+TT) decreased from 67.30% to 60.50%, whereas the proportion of patients who underwent neck dissection (SND+MRND+RND+BND) increased from 32.70% to 39.50% during the 5-year study period. Conclusion Despite the increase in rate of thyroid cancer due to earlier detection, increased rate of neck dissection was noted. PMID:25470609

Transoral laser surgery for laryngeal cancer.  

PubMed

Transoral laser microsurgery (TLM) was pioneered in the early 1970s as an approach to treat laryngeal pathology with precision and minimal thermal damage to the vocal cords. Over the last four decades, TLM has become an integral part of the treatment paradigm for patients with laryngeal cancer. TLM is one of the primary treatment options for early-stage laryngeal tumors. However, in recent years, surgeons have begun to develop TLM into a more versatile approach which can be used to address advanced laryngeal tumors. Although functional outcomes following TLM for advanced laryngeal disease are scarce, survival outcomes appear to be comparable with those reported for organ preservation strategies employing external beam radiation therapy (EBRT) and chemotherapy. In addition, TLM plays an important role in the setting of recurrent laryngeal cancer following primary irradiation. TLM has been demonstrated to decrease the need for salvage total laryngectomy resulting in improved functionality while retaining comparable oncologic outcomes. The aim of this review is to elucidate the indications, techniques, and oncological outcomes of TLM for advanced laryngeal cancers. PMID:24808950

Breast Cancer: Surgery at the South Egypt Cancer Institute  

PubMed Central

Breast cancer is the most frequent malignant tumor in women worldwide. In Egypt, it is the most common cancer among women, representing 18.9% of total cancer cases (35.1% in women and 2.2% in men) among the Egypt National Cancer Institute’s (NCI) series of 10,556 patients during the year 2001, with an age-adjusted rate of 49.6 per 100,000 people. In this study, the data of all breast cancer patients presented to the surgical department of the South Egypt cancer Institute (SECI) hospital during the period from Janurary 2001 to December 2008 were reviewed .We report the progress of the availability of breast cancer management and evaluation of the quality of care delivered to breast cancer patients. The total number of patients with a breast lump presented to the SECI during the study period was 1,463 patients (32 males and 1431 females); 616 patients from the total number were admitted at the surgical department .There was a decline in advanced cases. Since 2001, facilities for all lines of comprehensive management have been made accessible for all patients. We found that better management could lead to earlier presentation, and better overall outcome in breast cancer patients.The incidence is steadily increasing with a tendency for breast cancer to occur in younger age groups and with advanced stages.

Robotic surgery for rectal cancer: A systematic review of current practice  

PubMed Central

AIM: To give a comprehensive review of current literature on robotic rectal cancer surgery. METHODS: A systematic review of current literature via PubMed and Embase search engines was performed to identify relevant articles from january 2007 to november 2013. The keywords used were: “robotic surgery”, “surgical robotics”, “laparoscopic computer-assisted surgery”, “colectomy” and “rectal resection”. RESULTS: After the initial screen of 380 articles, 20 papers were selected for review. A total of 1062 patients (male 64.0%) with a mean age of 61.1 years and body mass index of 24.9 kg/m2 were included in the review. Out of 1062 robotic-assisted operations, 831 (78.2%) anterior and low anterior resections, 132 (12.4%) intersphincteric resection with coloanal anastomosis, 98 (9.3%) abdominoperineal resections and 1 (0.1%) Hartmann’s operation were included in the review. Robotic rectal surgery was associated with longer operative time but with comparable oncological results and anastomotic leak rate when compared with laparoscopic rectal surgery. CONCLUSION: Robotic colorectal surgery has continued to evolve to its current state with promising results; feasible surgical option with low conversion rate and comparable short-term oncological results. The challenges faced with robotic surgery are for more high quality studies to justify its cost. PMID:24936229

Incidence, Predictive Factors, and Clinical Outcomes of Acute Kidney Injury after Gastric Surgery for Gastric Cancer  

PubMed Central

Background Postoperative acute kidney injury (AKI), a serious surgical complication, is common after cardiac surgery; however, reports on AKI after noncardiac surgery are limited. We sought to determine the incidence and predictive factors of AKI after gastric surgery for gastric cancer and its effects on the clinical outcomes. Methods We conducted a retrospective study of 4718 patients with normal renal function who underwent partial or total gastrectomy for gastric cancer between June 2002 and December 2011. Postoperative AKI was defined by serum creatinine change, as per the Kidney Disease Improving Global Outcomes guideline. Results Of the 4718 patients, 679 (14.4%) developed AKI. Length of hospital stay, intensive care unit admission rates, and in-hospital mortality rate (3.5% versus 0.2%) were significantly higher in patients with AKI than in those without. AKI was also associated with requirement of renal replacement therapy. Multivariate analysis revealed that male gender; hypertension; chronic obstructive pulmonary disease; hypoalbuminemia (<4 g/dl); use of diuretics, vasopressors, and contrast agents; and packed red blood cell transfusion were independent predictors for AKI after gastric surgery. Postoperative AKI and vasopressor use entailed a high risk of 3-month mortality after multiple adjustments. Conclusions AKI was common after gastric surgery for gastric cancer and associated with adverse outcomes. We identified several factors associated with postoperative AKI; recognition of these predictive factors may help reduce the incidence of AKI after gastric surgery. Furthermore, postoperative AKI in patients with gastric cancer is an important risk factor for short-term mortality. PMID:24349249

Single-site robotic surgery in gynecologic cancer: a pilot study  

PubMed Central

Objective To discuss the feasibility of single-site robotic surgery for benign gynecologic tumors and early stage gynecologic cancers. Methods In this single institution, prospective analysis, we analyzed six patients who had undergone single-site robotic surgery between December 2013 and August 2014. Surgery was performed using the da Vinci Si Surgical System. Patient characteristics and surgical outcomes were analyzed. Results Single-site robotic surgery was performed successfully in all six cases. The median patient age was 48 years, and the median body mass index was 25.5 kg/m2 (range, 22 to 33 kg/m2). The median total operative time was 211 minutes, and the median duration of intracorporeal vaginal cuff suturing was 32 minutes (range, 22 to 47 minutes). The median duration of pelvic lymph node dissection was 31 minutes on one side and 27 minutes on the other side. Patients' postoperative courses were uneventful. The median postoperative hospital stay was 4 days. No postoperative complications occurred. Conclusion When used to treat benign gynecologic tumors and early stage gynecologic cancers, the single-site da Vinci robotic surgery is feasible, safe, and produces favorable surgical outcomes.

Prevalence of acute neuropathic pain after cancer surgery: A prospective study  

PubMed Central

Background and Aims: Acute neuropathic pain (ANP) is an under-recognised and under-diagnosed condition and often difficult to treat. If left untreated, it may further transform into persistent post-operative chronic pain leading to a disability. Aims: This prospective study was undertaken on 300 patients to identify the prevalence of ANP in the post-operative period by using a neuropathic pain detection questionnaire tool. Methods: This is an open-label study in which patients with six different types of cancer surgeries (Thoracic, gastro-intestinal, gynae/urology, bone/soft-tissue, head and neck and breast subgroups-50 each) were included for painDETECT questionnaire tool on the 2nd and 7th day surgery. Results: This study found a 10% point prevalence of ANP. Analysis showed that 25 patients had ‘possible’ ANP, the maximum from urological cancer surgery (6) followed by thoracic surgery (5). Five patients were found to have ‘positive’ ANP including 2 groin node dissection, 2 hemipelvectomy and 1 oesophagectomy. Conclusion: Significant relationship between severity of post-operative pain was found with the occurrence of ANP in the post-operative period requiring a special attention to neuropathic pain assessment. Larger studies are required with longer follow-up to identify accurately the true prevalence and causative factors of ANP after surgery. PMID:24700897

Emergency surgery for large bowel obstruction caused by cancer.  

PubMed

There are several options for surgical treatment of large bowel obstruction caused by cancer, depending on location of obstruction, intraoperative local findings (perforation, peritonitis, bowel dilatation proximal to obstruction) and patients' condition. Resection and anastomosis as one stage surgery would be prefered procedure. Anastomotic leakage, on the other hand, highly elevates risk of mortality and mobidity. The most important question is whether to, in resectable cases, perform primary resection with anastomosis or not. This study was retrospective and included 40 patients that have undergone emergency surgery for large bowel obstruction caused by cancer. According to whether resection and anastomosis was made at initial surgery or not, patients were grouped in group A (N = 18) and group B (N = 21), respectively. We have analysed the type of surgical procedure, days of hospitalization, mortality, anastomotic leakeage, wound infection and other postoperative complications. Our results show that there is no major difference in mortality and morbidity in these two groups, suggesting that for selected patients primary resection and anastomosis is a safe option of tratment with acceptable risk. Since there are no strict guidelines or scorring system which would point the tratment option the decision about the choice of procedure still remains the burden of surgeon and depends on its experience and subspeciality. Our experience recomends primary resection and anastomosis except in cases of bowel perforation on tumor site, in cases of extreme dilatation and atony of bowel proximal to obstruction site and severe hypoproteinemia and anemia.

Comparison of Compliance of Adjuvant Chemotherapy Between Laparoscopic and Open Surgery in Patients With Colon Cancer  

PubMed Central

Purpose Many studies have shown that the completion of adjuvant chemotherapy improves the survival rate. Recently, laparoscopic surgery has been used to treat patients with colon cancer. We analyzed the relationship between the completion of adjuvant chemotherapy and the operation method. Methods We retrospectively analyzed the medical records of 147 patients diagnosed with colon cancer from January 1, 2009, to May 31, 2012. The numbers of patients who underwent laparoscopic and open surgery were 91 and 56, respectively. We analyzed the relationship between the operation method and various factors such as the completion rate of chemotherapy, the patient's age, gender, and physical activity, the postoperative hospital stay, the start time of chemotherapy, and the patient's body mass index (BMI), TNM stage, and type of health insurance. Results In the laparoscopic surgery group, the postoperative hospital stay (13.5 ± 14.82 days vs. 19.6 ± 11.38 days, P = 0.001) and start time of chemotherapy (17.7 ± 17.48 days vs. 23.0 ± 15.00 days, P = 0.044) were shorter, but the percent complete of chemotherapy (71/91 [78.0%] vs. 38/56 [67.8%], P = 0.121), and survival rate (88/91 [96.7%], 47/56 [83.9%], P = 0.007) were higher than they were in the open surgery group. Patients who were elderly, had a low BMI, and a high American Society of Anesthesiologists score were less likely to complete adjuvant chemotherapy than other patients were. Conclusion Laparoscopic surgery shows a shorter postoperative hospital stay, a shorter start time of chemotherapy, and a higher survival rate. Laparoscopic surgery may be expected to increase compliance of chemotherapy and to improve survival rate. PMID:25580414

Doing more: trends in breast cancer surgery, 2005 to 2011.  

PubMed

An increasing number of women may be choosing mastectomy over breast-conserving surgery for breast cancer as well as undergoing more bilateral resection, immediate reconstruction, and prophylactic operations. Women who had breast cancer operations between 2005 and 2011 were selected from the National Surgical Quality Improvement Program database. Annual trends were explored using robust Poisson multivariable regression as were predictors for mastectomy versus breast-conserving surgery. A total of 85,401 women were identified. Mastectomy increased from 2005 to 2011, starting at 40 per cent in 2005 and peaking at 51 per cent in 2008 (P < 0.001). Bilateral resection, immediate reconstruction, and prophylactic mastectomy also increased (all P < 0.001). Independent predictors of mastectomy included young age, Asian race, invasive cancer (vs carcinoma in situ), bilateral resection, axillary dissection, higher American Society of Anesthesiologists class, and lower body mass index (all P < 0.001). There was an increase in mastectomy, bilateral resection, immediate reconstruction, and prophylactic mastectomy from 2005 to 2011. PMID:25569069

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.

Nanobiotechnology promotes noninvasive high-intensity focused ultrasound cancer surgery.  

PubMed

The successful cancer eradication in a noninvasive manner is the ultimate objective in the fight against cancer. As a "bloodless scalpel," high-intensity focused ultrasound (HIFU) is regarded as one of the most promising and representative noninvasive therapeutic modalities for cancer surgery. However, large-scale clinical applications of HIFU are still in their infancy because of critical efficiency and safety issues which remain to be solved. Fortunately, recently developed nanobiotechnology provides an alternative efficient approach to improve such important issues in HIFU, especially for cancer therapy. This Research News presents the very recent exciting progresses on the elaborate design and fabrication of organic, inorganic, and organic/inorganic hybrid nanoparticles for enhancing the HIFU ablation efficiency against tumor tissues. It is highly expected that this Research News can arouse more extensive research enthusiasm on the development of functional nanomaterials for highly efficient HIFU-based synergistic therapy, which will give a promising noninvasive therapeutic modality for the successful cancer therapy with minimal damage to surrounding normal tissues, due to the noninvasive and site-specific therapeutic features of HIFU.

Hereditary diffuse gastric cancer: surgery, surveillance and unanswered questions.  

PubMed

Hereditary diffuse gastric cancer (HDGC) is an inherited cancer-susceptibility syndrome characterized by autosomal dominance and high penetrance. In 30-50% of cases, a causative germline mutation in CDH1, the E-cadherin gene, may be identified. Female carriers of CDH1 mutations also have an increased (20-40%) risk of lobular breast cancer. Endoscopic surveillance of patients with CDH1 mutations is ineffective because early foci of HDGC are typically small and underlie normal mucosa. CDH1 mutation carriers are therefore offered the option of prophylactic gastrectomy, which commonly reveals early foci of invasive signet-ring cell cancer. We review recommendations for genetic testing, surveillance and prophylactic surgery in HDGC. Areas for future research are discussed, including development of new screening modalities, optimal timing of prophylactic gastrectomy, identification of additional causative mutations in HDGC, management of patients with CDH1 missense mutations and prevention/early detection of lobular breast cancer in CDH1 mutation carriers.

The Role of Non-Curative Surgery in Incurable, Asymptomatic Advanced Gastric Cancer  

PubMed Central

Background Although general agreement exists on palliative surgery with intent of symptom palliation in advanced gastric cancer (AGC), the role of non-curative surgery for incurable, asymptomatic AGC is hotly debated. We aim to clarify the role of non-curative surgery in patients with incurable, asymptomatic AGC under the first-line chemotherapy. Methods A total of 737 patients with incurable, asymptomatic advanced gastric adenocarcinoma between January 2008 and May 2012 at the Sun Yat-sen University Cancer Center were retrospectively analyzed, comprising 414 patients with non-curative surgery plus first-line chemotherapy, and 323 patients with first-line chemotherapy only. The clinicopathologic data, survival, and prognosis were evaluated, with propensity score adjustment for selection bias. Results The median overall survival (OS) outcomes significantly favored non-curative surgery group over first-line chemotherapy only group in entire population (28.00 versus 10.37 months, P?=?0.000), stage 4 patients (23.87 versus 10.37 months, P?=?0.000), young patients (28.70 versus 10.37 months, P?=?0.000) and elderly patients (23.07 versus 10.27 months, P?=?0.031). The median OS advantages of non-curative surgery over first-line chemotherapy only were also maintained when the analyses were restricted to single organ metastasis (P?=?0.001), distant lymph node metastasis (P?=?0.002), peritoneal metastasis (P?=?0.000), and multi-organ metastasis (P?=?0.010). Significant OS advantages of non-curative surgery over chemotherapy only were confirmed solid by multivariate analyses before and after adjustment on propensity score (P?=?0.000). Small subsets of patients with surgery of single metastatic lesion after previous curative gastrectomy, and with surgery of both primary and single metastatic sites showed sound median OS. Conclusions There is a role for non-curative surgery plus first-line chemotherapy for incurable, asymptomatic AGC, in terms of survival. Randomized controlled trials are warranted to fill a gap in knowledge about the value of metastectomy and patient selection strategies. PMID:24358318

INTRODUCTION An association between bullous pemphigoid (BP) and internal malignancy has been suggested. However, no reports have documented a dramatic improvement in BP after surgery for gastric cancer. PRESENTATION OF CASE An 82-year-old Japanese woman was admitted to a local hospital for severe fatigue. On examination, she was diagnosed with BP and gastric cancer. Her BP was resistant to steroid treatment; however, it improved dramatically after surgery for gastric cancer. DISCUSSION In this case, a strong relationship appeared to exist between BP and gastric cancer. CONCLUSION This is the first report of a dramatic improvement in BP after surgery for gastric cancer.

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

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.

The Result of Conversion Surgery in Gastric Cancer Patients with Peritoneal Seeding  

PubMed Central

Purpose Palliative gastrectomy and chemotherapy are important options for peritoneal seeding of gastric cancer. The treatment stage IV gastric cancer patient who respond to induction chemotherapy, is converted to gastrectomy (conversion therapy or conversion surgery). This study explored the clinical outcomes of gastric cancer patients with peritoneal seeding who had undergone conversion therapy. Materials and Methods Between 2003 and 2012, gastric cancer patients with peritoneal seeding, as determined by preoperative or intraoperative diagnosis were reviewed retrospectively. Clinicopathologic characteristics and clinical outcomes of patients with peritoneal seeding were analyzed. Results Forty-three patients were enrolled. Eighteen patients had undergone conversion surgery and 25 patients continued conventional chemotherapy. Among the 18 conversion patients, 10 received clinically curative resection. The median follow-up period was 28.5 months (range 8 to 60 months) and the total 3-year survival rate was 16.3%. The median survival time of the patients who received clinically curative conversion therapy was 37 months, and the 3-year survival rate was 50%. The median follow-up for non-curative gastrectomy patients was 18 months. No patient treated using chemotherapy survived to 3 years; the median survival time was 8 months. The differences in survival time between the groups was statistically significant (P<0.001). Conclusions In terms of survival benefits for gastric cancer patients with peritoneal seeding, clinically curative conversion therapy resulted in better clinical outcomes. PMID:25580359

[Current status of robotic surgery for gastric cancer].  

PubMed

Robotic surgery was launched in Japan in 2000.In particular, the development of the da Vinci S Surgical System was a major breakthrough. It was introduced in Japan for the first time through our hospital in January 2009. Since then, the number of surgical robots used has been dramatically increasing, with up to approximately 160 robots all over the country. To date, we have performed more than 500 robotic surgeries, including 180 gastrectomies, at our hospital. Our data suggest that compared with the conventional laparoscopic approach, the use of the da Vinci Surgical System in minimally invasive gastrectomy for gastric cancer might improve short-term outcomes, particularly in terms of preventing postoperative local complications. Thus, we believe that use of surgical robots become increasingly beneficial for more extensive resections and operations that require more advanced skills, even though a couple of issues remain to be solved, such as long operative time, high cost, and limited experience and evidence. In this article, the current status and future perspectives regarding robotic gastrectomy for gastric cancer are presented based on our experience and a review of the literature. PMID:25434438

Effect of tramadol on perioperative immune function in patients undergoing gastric cancer surgeries  

PubMed Central

Background: A prospective randomized controlled trial was designed to observe the effect of tramadol on T-lymphocyte subsets, activated T cell and natural killer (NK) cells of patients undergoing gastric cancer surgeries. Subjects and Methods: Thirty patients undergoing elective gastric cancer surgeries under general anesthesia were randomly divided into two groups. Before anesthesia induction, Group I did not receive any drugs and Group II received intramuscular tramadol 1 mg/kg. Peripheral venous blood samples were taken before anesthesia, 1 h after incision and postoperation. CD3+, CD3+ CD4+, CD3+ CD8+, CD3–CD16+ CD56+ (NK) cells and CD3+ human leukocyte antigen (HLA)-DR+ (activated T cell) were measured by flow cytometer. Results: One hour after incision, CD3+, CD3+ CD4+, CD3+ CD4+/CD3+ CD8+, CD3-CD16+ CD56+, and CD3+ HLA-DR+ cells in the experimental and control group were significantly decreased compared with their baselines (P < 0.05), while the values of Group I were lower than those of Group II (P < 0.05). After surgery, the values of Group I were lower than their baselines (P < 0.05). But the values of Group II had no significant difference compared with their baselines. Conclusion: Tramadol can reduce the decrease of T-lymphocytes subsets and NK cells, thus improve the cellular immune function in the perioperation of gastric cancer.

Chemotherapy versus surgery for initial treatment in advanced ovarian epithelial cancer  

PubMed Central

Background Epithelial ovarian cancer presents at an advanced stage in the majority of women. These women require surgery and chemotherapy for optimal treatment. Conventional treatment is to perform surgery first and then give chemotherapy. However, it is not yet clear whether there are any advantages to using chemotherapy before surgery. Objectives To assess whether there is an advantage to treating women with advanced epithelial ovarian cancer with chemotherapy before cytoreductive surgery (neoadjuvant chemotherapy (NACT)) compared with conventional treatment where chemotherapy follows maximal cytoreductive surgery. Search methods For the original review we searched, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2006), MEDLINE (Silver Platter, from 1966 to 1 Sept 2006), EMBASE via Ovid (from 1980 to 1 Sept 2006), CANCERLIT (from 1966 to 1 Sept 2006), PDQ (search for open and closed trials) and MetaRegister (most current search Sept 2006). For this update randomised controlled trials (RCTs) were identified by searching the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2011) and the Cochrane Gynaecological Cancer Specialised Register (2011), MEDLINE (August week 1, 2011), EMBASE (to week 31, 2011), PDQ (search for open and closed trials) and MetaRegister (August 2011). Selection criteria RCTs of women with advanced epithelial ovarian cancer (Federation of International Gynaecologists and Obstetricians (FIGO) stage III/IV) who were randomly allocated to treatment groups that compared platinum-based chemotherapy before cytoreductive surgery with platinum-based chemotherapy following cytoreductive surgery. Data collection and analysis Data were extracted by two review authors independently, and the quality of included trials was assessed by two review authors independently. Main results One high-quality RCT met the inclusion criteria. This multicentre trial randomised 718 women with stage IIIc/IV ovarian cancer to NACT followed by interval debulking surgery (IDS) or primary debulking surgery (PDS) followed by chemotherapy. There were no significant differences between the study groups with regard to overall survival (OS) (670 women; HR 0.98; 95% CI 0.82 to 1.18) or progression-free survival (PFS) (670 women; HR 1.01; 95% CI 0.86 to 1.17). Significant differences occurred between the NACT and PDS groups with regard to some surgically related serious adverse effects (SAE grade 3/4) including haemorrhage (12 in NACT group vs 23 in PDS group; RR 0.50; 95% CI 0.25 to 0.99), venous thromboembolism (none in NACT group vs eight in PDS group; RR 0.06; 95% CI 0 to 0.98) and infection (five in NACT group vs 25 in PDS group; RR 0.19; 95% CI 0.07 to 0.50). Quality of life (QoL) was reported to be similar for the NACT and PDS groups. Three ongoing RCTs were also identified. Authors’ conclusions We consider the use of NACT in women with stage IIIc/IV ovarian cancer to be a reasonable alternative to PDS, particularly in bulky disease. With regard to selecting who will benefit from NACT, treatment should be tailored to the patient and should take into account resectability, age, histology, stage and performance status. These results cannot be generalised to women with stage IIIa and IIIb ovarian cancer; in these women, PDS is the standard. We await the results of three ongoing trials, which may change these conclusions. PMID:22895947

Transoral videolaryngoscopic surgery for oropharyngeal, hypopharyngeal, and supraglottic cancer.  

PubMed

In this retrospective cohort study, we evaluated the oncological and functional outcomes of transoral videolaryngoscopic surgery (TOVS). Using distending laryngoscope and videolaryngoscope, wide operative field and working space could be obtained and tumor could be resected in en bloc. Sixty patients with T1, T2, and selected T3 laryngeal or pharyngeal squamous cell carcinomas (Stage I: n = 17, Stage II: n = 16, Stage III: n = 7, Stage IV: n = 20 cases) were enrolled and followed up for at least 24 months or until the patient's death. Fifty-three patients underwent initial treatment, and seven patients had recurrent cancer after chemoradiation. In principle, node-positive patients underwent a simultaneous neck dissection. Patients with multiple nodal metastases or a positive surgical margin received postoperative radiotherapy. For initial treatment, the 5-year overall survival and disease-specific survival rates were 77 and 95 %, respectively. For supraglottic and hypopharyngeal cancers, the 5-year laryngeal preservation rates were 89 and 96 %, respectively. For salvage surgery, the overall survival, disease-specific survival, and laryngeal preservation rates were 75, 75, and 80 %, respectively. The median times before patients could resume eating and swallowing a soft diet were 6 and 9 days, respectively. The patients' Functional Outcome Swallowing Scale stages were 0-2 in 93.3 % of the cases and 3 or 4 in 6.7 % of the cases. A percutaneous endoscopic gastrostomy was indicated for 1 (1.7 %) patient. Four (6.7 %) patients received transient tracheostomy. TOVS is a satisfactory and minimally invasive treatment option for laryngeal and pharyngeal cancers. PMID:23728895

Salvage cytoreductive surgery for patients with recurrent endometrial cancer: a retrospective study  

PubMed Central

Background Salvage cytoreductive surgery (SCR) has been shown to improve the survival of cancer patients. This study aimed to determine the survival benefits of SCR for recurrent endometrial cancer in Chinese population. Methods Between January 1995 and May 2012, 75 Chinese patients with recurrent endometrial cancer undergoing SCR were retrospectively analyzed. Results 43 patients (57.3%) had R0 (no visible disease), 15 patients (20.0%) had R1 (residual disease ?1 cm), and 17 (22.7%) had R2 (residual disease >1 cm) Resection. 35 patients (46.7%) had single, and 40 (53.3%) had multiple sites of recurrence. The median survival time was 18 months, and 5-year overall survival (OS) rate were 42.0%. Multivariate analysis showed that residual disease ?1 cm and high histology grade were significantly associated with a better OS. The size of the largest recurrent tumors (?6 cm), solitary recurrent tumor, and age at recurrence (?56 years old) were associated with optimal SCR. Conclusion Optimal SCR and high histology grade are associated with prolonged overall survival for patients with recurrent endometrial cancer. Patients with young age, tumor size?surgery.

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.

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.

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

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.

The role of the robotic technique in minimally invasive surgery in rectal cancer  

PubMed Central

Laparoscopic rectal surgery is feasible, oncologically safe, and offers better short-term outcomes than traditional open procedures in terms of pain control, recovery of bowel function, length of hospital stay, and time until return to working activity. Nevertheless, laparoscopic techniques are not widely used in rectal surgery, mainly because they require a prolonged and demanding learning curve that is available only in high-volume and rectal cancer surgery centres experienced in minimally invasive surgery. Robotic surgery is a new technology that enables the surgeon to perform minimally invasive operations with better vision and more intuitive and precise control of the operating instruments, promising to overcome some of the technical difficulties associated with standard laparoscopy. The aim of this review is to summarise the current data on clinical and oncological outcomes of minimally invasive surgery in rectal cancer, focusing on robotic surgery, and providing original data from the authors’ centre.

Risk factors for dysphagia after transoral videolaryngoscopic surgery for laryngeal and pharyngeal cancer.  

PubMed

Background. Transoral surgery is gaining attention as a minimally invasive treatment option for laryngeal and pharyngeal cancer. Postoperative swallowing function is satisfactory in most cases, but occasionally dysphagia persists. Methods. Swallowing function of 86 patients who underwent transoral videolaryngoscopic surgery (TOVS) for laryngeal and pharyngeal cancers was evaluated by the functional outcome swallowing scale (FOSS) and risk factors for dysphagia were identified. Results. FOSS stage was 0-1 in 90%, 2 in 5.8%, 3 in 3.5%, and 4 in 1.2% of the patients. Only one patient had indication for percutaneous endoscopic gastrostomy (PEG). Univariate analysis revealed that resection of pyriform sinus (p = 0.0280) and arytenoid (p = 0.0139), pulmonary dysfunction (p = 0.0353), and large mucosal defect (p = 0.0223) were associated with postoperative dysphagia. Conclusions. Although the rate of PEG dependency is low in transoral surgery, surgeons should mention the risk of postoperative dysphagia when counseling patients preoperatively. Head Neck, 2014.

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.

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.

Can intravenous patient-controlled analgesia be omitted in patients undergoing laparoscopic surgery for colorectal cancer?  

PubMed Central

Purpose Opioid-based intravenous patient-controlled analgesia (IV-PCA) is a popular method of postoperative analgesia, but many patients suffer from PCA-related complications. We hypothesized that PCA was not essential in patients undergoing major abdominal surgery by minimal invasive approach. Methods Between February 2013 and August 2013, 297 patients undergoing laparoscopic surgery for colorectal cancer were included in this retrospective comparative study. The PCA group received conventional opioid-based PCA postoperatively, and the non-PCA group received intravenous anti-inflammatory drugs (Tramadol) as necessary. Patients reported their postoperative pain using a subjective visual analogue scale (VAS). The PCA-related adverse effects and frequency of rescue analgesia were evaluated, and the recovery rates were measured. Results Patients in the PCA group experienced less postoperative pain on days 4 and 5 after surgery than those in the non-PCA group (mean [SD] VAS: day 4, 6.2 [0.3] vs. 7.0 [0.3], P = 0.010; and day 5, 5.1 [0.2] vs. 5.5 [0.2], P = 0.030, respectively). Fewer patients in the non-PCA group required additional parenteral analgesia (41 of 93 patients vs. 53 of 75 patients, respectively), and none in the non-PCA group required rescue PCA postoperatively. The incidence of postoperative nausea and vomiting was significantly higher in the non-PCA group than in the PCA group (P < 0.001). The mean (range) length of hospital stay was shorter in the non-PCA group (7.9 [6-10] days vs. 8.7 [7-16] days, respectively, P = 0.03). Conclusion Our Results suggest that IV-PCA may not be necessary in selected patients those who underwent minimal invasive surgery for colorectal cancer.

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.

Comparison of long-term oncologic outcomes of stage III colorectal cancer following laparoscopic versus open surgery  

PubMed Central

Purpose The oncologic outcomes after performing laparoscopic surgery (LS) compared to open surgery (OS) are still under debate and a concern when treating patients with colon cancer. The aim of this study was to compare the long-term oncologic outcomes of LS and OS as treatment for stage III colorectal cancer patients. Methods From January 2001 to December 2007, 230 patients with stage III colorectal cancer who had undergone LS or OS in this single center were assessed. Data were analyzed according to intention-to-treat. The primary endpoints were disease-free survival and overall survival. Results A total of 230 patients were entered into the study (114 patients had colon cancer-33 underwent LS and 81 underwent OS; 116 patients had rectal cancer-44 underwent LS and 72 underwent OS). The median follow-up periods for the colon and rectal cancer groups were 54 and 53 months, respectively. The overall conversion rate was 12.1% (n = 4) for colon cancer, and 4.5% (n = 2) for rectal cancer. Disease-free 5-year survival of colon cancer was 84.3% and 90% in LS group (LG) and OS group (OG), respectively, and that of rectal cancer was 83% and 74.6%, respectively (P > 0.05). Overall 5-year survival for colon cancer was 72.2% and 71.3% for LG and OG, respectively, and that for rectal cancer was 67.6% and 59.2%, respectively (P > 0.05). Conclusion The long-term analyses for oncologic aspects of our study may confirm the safety of LS compared to OS in stage III colorectal cancer patients. PMID:25553319

Methods Patients in the COLOR II randomized trial, comparing laparoscopic and open surgery for rectal cancer, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-CR38 questionnaire before surgery, and after 4?weeks, 6, 12 and 24?months. Adjusted mean differences on a 100-point scale were calculated using changes from baseline value at the various time points in the domains of sexual functioning, sexual enjoyment, male and female sexual problems, and micturition symptoms. Results Of 617 randomized patients, 385 completed this phase of the trial. Their mean age was 67·1?years. Surgery caused an anticipated reduction in genitourinary function after 4?weeks, with no significant differences between laparoscopic and open approaches. An improvement in sexual dysfunction was seen in the first year, but some male sexual problems persisted. Before operation 64·5 per cent of men in the laparoscopic group and 55·6 per cent in the open group reported some degree of erectile dysfunction. This increased to 81·1 and 80·5 per cent respectively 4?weeks after surgery, and 76·3 versus 75·5 per cent at 12?months, with no significant differences between groups. Micturition symptoms were less affected than sexual function and gradually improved to preoperative levels by 6?months. Adjusting for confounders, including radiotherapy, did not change these results. Conclusion Sexual dysfunction is common in patients with rectal cancer, and treatment (including surgery) increases the proportion of patients affected. A laparoscopic approach does not change this.

Effect of Interval to Definitive Breast Surgery on Clinical Presentation and Survival in Early-Stage Invasive Breast Cancer  

SciTech Connect

Purpose: To examine the effect of clinical presentation and interval to breast surgery on local recurrence and survival in early-stage breast cancer. Methods and Materials: The data from 397 patients with Stage T1-T2N0 breast carcinoma treated with conservative surgery and breast radiotherapy between 1985 and 1992 were reviewed at the London Regional Cancer Program. The clinical presentation consisted of a mammogram finding or a palpable lump. The intervals from clinical presentation to definitive breast surgery used for analysis were 0-4, >4-12, and >12 weeks. The Kaplan-Meier estimates of the time to local recurrence, disease-free survival, and cause-specific survival were determined for the three groups. Cox regression analysis was used to evaluate the effect of clinical presentation and interval to definitive surgery on survival. Results: The median follow-up was 11.2 years. No statistically significant difference was found in local recurrence as a function of the interval to definitive surgery (p = .424). A significant difference was noted in disease-free survival (p = .040) and cause-specific survival (p = .006) with an interval of >12 weeks to definitive breast surgery. However, the interval to definitive surgery was dependent on the presentation for cause-specific survival, with a substantial effect for patients with a mammographic presentation and a negligible effect for patients with a lump presentation (interaction p = .041). Conclusion: The results of this study suggest that an interval of >12 weeks to breast surgery might be associated with decreased survival for patients with a mammographic presentation, but it appeared to have no effect on survival for patients presenting with a palpable breast lump.

Information control for image-guided surgery: method and implementation  

NASA Astrophysics Data System (ADS)

Computer-assisted surgery technology relies heavily on multi-modality medical image and multimedia information. To systematically manage this information is a challenging task due to fast information growth and geographical expansion of the computer-assisted surgery (CAS) field. After many years developing image-guided surgery techniques, types and media of information are rapidly growing. CAS can grow from a traditional single suite containing only one operating room with a workstation, to a distributed CAS center that can include multiple operating rooms and a control room in order to distribute CAS service throughout a large medical center or an entire metropolitan area. This expansion increases the sophistication of information management or CAS significantly. This paper first identifies different types of multi-modality information and multimedia information involved in the CAS field, and then presents strategies and methods of managing this information. We discuss our CAS system developed at Wayne State University. Detroit Medical Center as a typical example.

A new stage of sentinel node navigation surgery in early gastric cancer.  

PubMed

Sentinel node (SN) navigation surgery is expected to realize organ- and function-preserving surgery with SN mapping, and has been applied in operations for breast cancer and melanoma. But there has been no definite evidence for the SN concept in gastric cancer. A prospective multicenter trial to confirm the SN concept for gastric cancer conducted by the Japan Society of Sentinel Node Navigation Surgery reported that the SN detection rate, sensitivity of positive SNs, and accuracy of nodal status are 97.5 % (387/397), 93 % (53/57), and 99 % (383/387), respectively. A detailed analysis of the trial suggested that strictly the "lymphatic basin concept" rather than the "SN concept" was confirmed in early gastric cancer. The Japan Society of Sentinel Node Navigation Surgery started a new trial of function-preserving gastrectomy with lymphatic basin dissection (LBD) for early gastric cancer without metastasis in SNs on the basis of this promising outcome of the trial. It is supposed that LBD guarantees curability in SN navigation surgery for early gastric cancer. Full-thickness resection or endoscopic submucosal dissection in combination with laparoscopic LBD will soon be a new treatment option for early gastric cancer. PMID:25433568

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

Effect of triclosan-coated sutures on surgical site infection after gastric cancer surgery via midline laparotomy  

PubMed Central

Purpose Surgical site infection (SSI) after open abdominal surgery is still a frequently reported nosocomial infection. To reduce the incidence of SSI, triclosan-coated sutures with antiseptic activity (Vicryl Plus) were developed. The aim of this study was to analyze the effect of Vicryl Plus on SSI after gastric cancer surgery via midline laparotomy. Methods A total of 916 patients who underwent gastric cancer surgery at Samsung Medical Center between December 2009 and September 2011 were prospectively collected. We examined the occurrence of SSI (primary endpoint), assessments of wound healing (secondary endpoint). They were evaluated postoperatively on days 3, 7, and 30. Results Of the 916 patients, 122 were excluded postoperatively by screening (out of the study protocol, adverse events, etc.). The remaining 794 patients were enrolled and monitored postoperatively. The cumulative SSI incidence was 11 cases (1.39%; 95% confidence interval [CI], 0.77-2.50) on day 30. Seromas were most frequently detected in wound healing assessments, with a cumulative incidence of 147 cases (18.51%; 95% CI, 15.98-21.39) on day 30. Conclusion The use of triclosan-coated sutures (Vicryl Plus) for abdominal wall closure can reduce the number of SSIs in gastric cancer surgery. PMID:25485239

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.

The effect of laparoscopic surgery in stage II and III right-sided colon cancer: a retrospective study  

PubMed Central

Background This retrospective study compared the clinicopathological results among three groups divided by time sequence to evaluate the impact of introducing laparoscopic surgery on long-term oncological outcomes for right-sided colon cancer. Methods From April 1986 to December 2006, 200 patients who underwent elective surgery with stage II and III right-sided colon cancer were analyzed. The period for group I referred back to the time when laparoscopic approach had not yet been introduced. The period for group II was designated as the time when first laparoscopic approach for right colectomy was carried out until we overcame its learning curve. The period for group III was the period after overcoming this learning curve. Results When groups I and II, and groups II and III were compared, overall survival (OS) did not differ significantly whereas disease-free survival (DFS) in groups I and III were statistically higher than in group II (P?=?0.042 and P?=?0.050). In group III, laparoscopic surgery had a tendency to provide better long-term OS ( P?=?0.2036) and DFS ( P?=?0.2356) than open surgery. Also, the incidence of local recurrence in group III (2.6%) was significantly lower than that in groups II (7.4%) and I (12.1%) ( P?=?0.013). Conclusions Institutions should standardize their techniques and then provide fellowship training for newcomers of laparoscopic colon cancer surgery. This technique once mastered will become the gold standard approach to colon surgery as it is both safe and feasible considering the oncological and technical aspects. PMID:22594580

Comparison of laparoscopy-assisted surgery and laparotomy for treating locally advanced distal gastric antral cancer  

PubMed Central

The aim of this study was to investigate the safety, feasibility and mid-term results of laparoscopy-assisted surgery in the treatment of locally advanced gastric antral cancer. The clinical data of 50 patients who received laparoscopy-assisted surgery (Group A) and 62 patients who were treated by conventional laparotomy (Group B) from August 2009 to January 2011 were retrospectively analyzed. The surgical incision length, the volume of blood loss, the intestinal function recovery time, the postoperative complications, the postoperative 1- and 3-year cumulative survival rates and the average survival time in the two groups were observed. The results of the two groups were compared using the ?2 test for the enumeration data, a t-test for the numerical data and a Wilcoxon rank sum test for the skewed data. In addition, the Kaplan-Meier method of single factor analysis was utilized to comwpare the 1- and 3-year cumulative survival rates, as well as the average survival time of the two groups. The results indicated that the duration of surgery for Group A was significantly longer compared with that of Group B (P<0.05); however, the incision length and the volume of intraoperative blood loss in Group A were significantly smaller compared with those of Group B (P<0.01). Furthermore, in Group A, the recovery of intestinal function was more rapid and the time spent in hospital was shorter. However, between Groups A and B, the respective number of dissected lymph nodes (16.3 and 17.2), 1-year survival rates (86.0 and 88.6%) and 3-year survival rates (52.6 and 53.7%) were not significantly different (P<0.05). The results indicate that laparoscopy-assisted surgery is a safe approach for the treatment of locally advanced gastric antral cancer and has beneficial treatment effects. Laparoscopy-assisted surgery is advantageous compared with laparotomy, due to the smaller incision length and reductions in intraoperative blood loss, invasiveness, postoperative recovery time and the number of complications.

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.

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

Impact of the Time Interval Between MDCT Imaging and Surgery on the Accuracy of Identifying Metastatic Disease in Patients With Pancreatic Cancer.  

PubMed

OBJECTIVE. Pancreatic adenocarcinoma is a rapidly progressive malignancy characterized by its tendency for early metastatic spread. MDCT is the primary diagnostic modality for the preoperative staging of patients with pancreatic cancer, with an accuracy established in multiple studies. However, for a variety of reasons, there is often a prolonged interval between staging MDCT and the surgical intervention. This study examines the relationship between the interval between imaging and surgery and the accuracy of MDCT in determining the presence or absence of metastatic disease at surgery in patients with pancreatic cancer. MATERIALS AND METHODS. Patients were identified who had undergone surgery for pancreatic cancer at our institution with a dedicated preoperative pancreas-protocol MDCT performed in our department. Findings from the preoperative MDCT report were correlated with the operative findings, as well as the time between imaging and surgery. RESULTS. Two hundred ninety-two MDCT scans were performed on 256 patients who underwent exploration for pancreatic adenocarcinoma. The patients had a median age of 67 years (range, 30-95 years), and 51.6% (132/256) were male. The median time between MDCT and surgical exploration was 15.5 days (range, 1-198 days). MDCT correctly predicted the absence of metastatic disease at surgery in 233 of 274 (85.0%) studies. MDCT was more accurate in predicting the absence of metastatic disease if the study was performed within 25 days of surgery than it was if the study was performed within more than 25 days of surgery (89.3% vs 77.0%; p = 0.0097). Furthermore, regression models showed that the negative predictive value of a given MDCT significantly decreased after approximately 4 weeks. CONCLUSION. MDCT is an accurate method to stage patients with pancreatic cancer, but its accuracy in excluding distant metastatic disease depreciates over time. Patients should undergo a repeat MDCT within 25 days of any planned definitive operative intervention for pancreatic cancer to avoid unexpectedly finding metastatic disease at surgery. PMID:25539271

Multi-institute study finds many men with prostate cancer can avoid early surgery  

Cancer.gov

New research suggests that many men with prostate cancer do not need immediate treatment, especially if they have low PSA scores or low-risk tumors that are unlikely to grow and spread. The multi-center study, published July 18 in the New England Journal of Medicine, compared prostate cancer surgery soon after diagnosis to observation in men with early-stage prostate tumors detected by PSA screening. Overall, most men did not benefit from surgery – it did not reduce the likelihood they would die from prostate cancer or other causes. The study included researchers from the Baylor College of Medicine (home to the Dan L. Duncan Cancer Center), the Siteman Cancer Center at Washington University School of Medicine, and the Minneapolis Veterans Administration Health Care System.

Incidence and Predictors of Venous Thromboembolism After Debulking Surgery for Epithelial Ovarian Cancer  

PubMed Central

Objective The aim of this study was to determine the incidence and the risk factors of venous thromboembolism (VTE) within 30 days after primary surgery for epithelial ovarian cancer (EOC). Methods In a historical cohort study, we estimated the postoperative 30-day cumulative incidence of VTE among consecutive Mayo Clinic patients undergoing primary cytoreduction for EOC between January 2, 2003, and December 29, 2008. We tested perioperative patient characteristics and process-of-care variables (defined by the National Surgical Quality Improvement Program, >130 variables) as potential predictors of postoperative VTE using the Cox proportional hazards modeling. Results Among 569 cases of primary EOC cytoreduction and/or staging and no recent VTE, 35 developed symptomatic VTE within 30 days after surgery (cumulative incidence = 6.5%; 95% confidence interval, 4.4%–8.6%). Within the cohort, 95 (16.7%) received graduated compression stockings (GCSs), 367 (64.5%) had sequential compression devices + GCSs, and 69 (12.1%) had sequential compression devices + GCSs + postoperative heparin, with VTE rates of 1.1%, 7.4%, and 5.8%, respectively (P = 0.07, ?2 test). The remaining 38 (6.7%) received various other chemical and mechanical prophylaxis regimens. In the multivariate analysis, current or past tobacco smoking, longer hospital stay, and a remote history of VTE significantly increased the risk for postoperative VTE. Conclusions Venous thromboembolism is a substantial postoperative complication among women with EOC, and the high cumulative rate of VTE within 30 days after primary surgery suggests that a more aggressive strategy is needed for VTE prevention. In addition, because longer hospital stay is independently associated with a higher risk for VTE, methods to decrease length of stay and minimize factors that contribute to prolonged hospitalization are warranted.

The changes of blood platelet activation in breast cancer patients before surgery, after surgery, and in various phases of the chemotherapy.  

PubMed

Blood platelets from patients with cancer (before or after the surgery) exhibit a variety of qualitative abnormalities. Different anti-cancer drugs may also induce the oxidative/nitrative stress in blood platelets and change their hemostatic properties. The aim of our study was to explain the effect of superoxide anion radicals ([Formula: see text]) production on hemostatic properties of blood platelets (activated by a strong physiological agonist - thrombin) from breast cancer patients before the surgery, after the surgery, and after various phases (I-IV) of chemotherapy (doxorubicin and cyclophosphamide). Patients were hospitalized in the Department of Oncological Surgery and at the Department of Chemotherapy, Medical University of Lodz, Poland. We measured the platelet aggregation as the marker of hemostatic activity of blood platelets. We observed an increase of [Formula: see text] in thrombin-activated blood platelets from patients with breast cancer (before or after the surgery and after various phases of the chemotherapy) compared to the healthy group. Our other experiments demonstrated that aggregation (induced by thrombin) of blood platelets from patients with breast cancer before the surgery, after the surgery, and after various phases of the chemotherapy differs from aggregation of platelets obtained from healthy volunteers. Moreover, our results showed the correlation between the [Formula: see text] generation and changes of platelet aggregation in breast cancer patients before the surgery, after the surgery, and after the chemotherapy (I and IV phases). Considering the data presented in this study, we suggest that the production of [Formula: see text] in blood platelets (activated by thrombin) obtained from breast cancer patients may induce the changes of platelet aggregation, which may contribute in thrombosis in these patients.

[Focal surgery in testis cancer: current state of the art].  

PubMed

Radical orchiectomy is the standard treatment of testicular neoplasia causing androgen insufficiency, infertility and psychological stress. Focal surgery allows the preservation of fertility, endocrine function and integrity of the genital anatomy, with preservation of the image of the male body. The EAU guidelines suggest focal surgery in case of synchronous bilateral tumors, metachronous contralateral tumours, tumour in solitary testis with normal pre-operative testosterone levels, when the tumor volume less than 30% of the testicular volume. There are two focal surgical techniques: tumorectomy and polar resection, followed by biopsies and frozen section of the resection bed. In case of benign tumours, the treatment is often curative. In case of malignancy, carcinoma in situ is frequently found in the surrounding tissues. Adjuvant treatment with chemotherapy or radiotherapy is performed with a fair success rate. These adjuvant treatments reduce or delete the functional benefits achieved by conservative surgery. The evidence of the literature suggests that focal surgery is a valid option for all patients with testicular tumours that are not palpable and small sized, with the advantage of avoiding unnecessary radical orchiectomy in most cases. Therefore, the selection criteria for focal surgery are the mass size (less than 25 mm) and a safety distance of the tumor from the rete testis, in order to preserve testicular vascularization. A close follow-up with ultrasound, testicular markers and radiological examinations is mandatory in case of germ cell neoplasia treated conservatively in patients with indications for conservative surgery.

Long-Term Survival and Recurrence Outcomes Following Surgery for Distal Rectal Cancer  

PubMed Central

Background Treatment of distal rectal cancer remains clinically challenging and includes proctectomy and coloanal anastomosis (CAA) or abdominoperineal resection (APR). The purpose of this study is to evaluate operative and pathologic factors associated with long-term survival and local recurrence outcomes in patients treated for distal rectal cancer. Methods A retrospective consecutive cohort study of 304 patients treated for distal rectal cancer with radical resection from 1993 to 2003 was performed. Patients were grouped by procedure (CAA or APR). Demographic, pathologic, recurrence, and survival data were analyzed utilizing chi-square analysis for comparison of proportions. Survival analysis was performed using Kaplan–Meier method and log-rank test for univariate and Cox regression for multivariate comparison. Results The median tumor distance from the anal verge was 2 cm [interquartile range (IQR) 0.5–4 cm]. Margins were negative in all but four patients (one distal, 0.3%; three radial, 1%). The 5-year overall survival rate was 82% (88.6% stage pI, 80.5% stage pII, 67.9% stage pIII). Older age, advanced pathologic stage, presence of lymphovascular or perineural invasion, earlier treatment period, and APR surgery type were associated with worse survival on multivariate analysis. The 5-year local recurrence rate was 5.3% after CAA and 7.9% after APR (p = 0.33). Conclusions Low rates of local recurrence and good overall survival can be achieved after treatment of distal rectal cancer with stage-appropriate chemoradiation and proctectomy with CAA or APR. Sphincter preservation can be achieved even with distal margins less than 2 cm. PMID:20552409

Evaluation of leptin serum concentrations during surgery and first-line chemotherapy in primary epithelial ovarian cancer patients  

PubMed Central

Aim of the study The available data on serum leptin levels in ovarian cancer present contradictory results. The majority of authors report lower leptin levels in those patients in comparison to healthy individuals. However, there is no data regarding leptin concentrations during therapy in women with primary epithelial ovarian cancer. Material and methods Blood samples were collected at the time of diagnosis, after initial surgery, and after first-line chemotherapy. Leptin serum concentrations were analysed using ELISA technique. Additionally, parallel measurements of CA125 levels were performed. Results Fifty-three patients with primary epithelial ovarian cancer met the inclusion criteria and were included in our study. Our analysis revealed a significant difference in mean preoperative serum leptin concentrations between early and advanced ovarian cancer patients (p < 0.0001). We identified statistically significant elevation of mean serum leptin levels (p < 0.001) after complete macroscopic cytoreduction and after first-line chemotherapy in advanced ovarian cancer cases. Discussion In this cohort, a significant elevation of postoperative serum leptin levels after complete macroscopic cytoreduction were shown. Moreover, elevation of leptin levels corresponded with remission after chemotherapy. Further studies are needed to determine if leptin can be a potential marker of surgery completeness as well as a marker in chemotherapy response evaluation. PMID:25477753

Laparoscopic radical gastrectomy versus traditional open surgery in elderly patients with gastric cancer: Benefits and complications  

PubMed Central

This study was conducted to compare the therapeutic effect and complications of laparoscopic radical gastrectomy (LRG) with those of traditional open surgery in elderly patients with gastric cancer (GC). We conducted a retrospective comparison of therapeutic efficacy and complications between elderly patients with GC (defined as those aged ?70 years) who received laparoscopic gastrectomy and those who underwent gastrectomy by open surgery. A total of 108 patients who either underwent laparoscopic surgery (n=54) or traditional open surgery (n=54) at the General Hospital of Lanzhou Military Region between June, 2008 and March, 2009 were analyzed. Compared to traditional open surgery, LRG exhibited several advantages, such as being less invasive, with less intraoperative blood loss, shorter bedbound time, less intubation time, low frequency of fever, less time to normal diet, shorter hospital stay and a low overall incidence of complications. No significant difference was observed between laparoscopic and open surgery in terms of operative time and number of lymph nodes dissected. The 3-year cancer recurrence and mortality rates were similar in the two groups. In conclusion, LRG is a safe and effective procedure for the management of GC in elderly patients and was found to be superior to traditional open surgery regarding the short-term curative effect. Therefore, LRG represents a feasible and safe surgical approach for elderly patients with GC. PMID:24940489

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

Mayo Clinic study finds surgery or radiation most often sought for low-risk prostate cancer  

Cancer.gov

Few physicians recommend active surveillance for low-risk prostate cancer rather than pursuing surgery or radiation, according to a Mayo Clinic study being presented at the North Central Section of the American Urological Association's annual meeting Oct. 10–13 in Chicago. While active surveillance is widely regarded as an effective strategy for managing low-risk prostate cancer, a Mayo Clinic study of 643 urologists and radiation oncologists found that only 21 percent of physicians studied recommended the strategy while 47 percent recommended surgery and 32 percent recommended radiation therapy.

Contralateral axillary node metastasis from recurrence after conservative breast cancer surgery.  

PubMed

Sentinel lymph node detection (SLND) with radiocolloid has become widely used for evaluation of nodal metastasis in primary breast cancer. However, the procedure for recurrent breast cancer is not well established. Contralateral axillary node metastasis is uncommon. We report 2 cases of contralateral axillary node metastasis with recurrent breast cancer. In the first case, contralateral node metastasis was found by SLND. In the other case without SLND, contralateral node metastasis developed after resection of local recurrence. FDG-avid contralateral node was pathologically diagnosed as metastasis. The SLND might be useful in patients with local recurrence after conservative breast cancer surgery. PMID:24368539

Single-port video-assisted thoracoscopic surgery for lung cancer  

PubMed Central

In 2004, novel results using pulmonary wedge resection executed through single-port video-assisted thoracoscopic surgery (VATS) was first described. Since that time, single-port VATS has been advocated for the treatment of a spectrum of thoracic diseases, especially lung cancer. Lung cancer remains one of the top three cancer-related deaths in Taiwan, and surgical resection remains the “gold standard” for early-stage lung cancer. Anatomical resections (including pneumonectomy, lobectomy, and segmentectomy) remain the primary types of lung cancer surgery, regardless of whether conventional open thoracotomy, or 4/3/2-ports VATS are used. In the past three years, several pioneers have reported their early experiences with single-port VATS lobectomy, segmentectomy, and pneumonectomy for lung cancer. Our goal was to appraise their findings and review the role of single-port VATS in the treatment of lung cancer. In addition, the current concept of mini-invasive surgery involves not only smaller resections (requiring only a few incisions), but also sub-lobar resection as segmentectomy. Therefore, our review will also address these issues. PMID:24455171

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.

Acquired lymphangiectasis following surgery and radiotherapy of breast cancer.  

PubMed

Acquired lymphangiectasia (AL) is a significant and rare complication of surgery and radiotherapy. We report lymphangiectasia in a 40-year-old woman who had undergone radical mastectomy and radiotherapy. After 4 years of combined therapy, she developed multiple vesicles and bullae. Skin biopsy confirmed the diagnosis of lymphangiectasia. The case is unique as it is not associated with lymphedema, which is a usual accompaniment of lymphangiectasia following surgery and radiotherapy. AL is usually asymptomatic, but trauma may cause recurrent cellulitis. Treatment modalities include electrodessication, surgical excision, sclerotherapy and carbon dioxide laser ablation.

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

Side docking: an alternative docking method for gynecologic robotic surgery.  

PubMed

The authors propose an alternative method of robotic docking for gynecologic surgery. In this side-docking method, the robot is docked at an approximately 45° angle to the lower torso, aligned with the outer border of either the left or right stirrup, depending on the surgeon's preference for left or right side-docking. The remainder of the patient and trocar setup is similar to traditional docking. The authors have had an excellent experience with this method as there does not seem to be an increased risk of robotic arm collision as long as the surgeon respects the basic principle of maintaining at least an 8- to 10-cm distance between each of the instrument ports. The significantly improved access to the vagina and perineum may facilitate robotically assisted gynecologic surgical procedures and reduce assistant fatigue and the potential for injury due to a collision with the robotic arms.

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

Malnutrition at the Time of Surgery Affects Negatively the Clinical Outcome of Critically Ill Patients with Gastrointestinal Cancer  

PubMed Central

Introduction: Malnutrition is a frequent concomitant of surgical illness, especially in gastrointestinal cancer surgery. The aim of the study was to assess the prevalence of malnutrition in the GI cancer patients and its relation with clinical outcome. We also examined associations between the energy balance and clinical outcomes in these patients. Methods: Prospective study on 694 surgical patients treated in the ICU of the UHC of Tirana. Patients were divided into well-nourished and malnourished groups according to their nutritional status. Multiple regression analysis was used to analyze the effect of malnutrition and cumulated energy balance on clinical outcome. Results: The prevalence of pre-operative malnutrition was 65.3% for all surgical patients and 84.9% for gastrointestinal cancer patients. Malnutrition, as analyzed by a multivariate logistic regression model, is an independent risk factor for higher complications, infections, and mortality, longer stay in the ventilator and ICU. Also this model showed that cumulated energy balance correlated with infections, and mortality and was independently associated with the length ventilator and ICU stay. Conclusion: This study shows that malnutrition is a significant problem in surgical patients, especially in patients with gastrointestinal cancer. Malnutrition and cumulated energy deficit in gastro-intestinal surgery patients with malignancy is an independent risk factor on increased post-operative morbidity and mortality. PMID:25568549

Laparoscopic fertility-sparing surgery for early stage ovarian cancer: a single-centre case series and systematic literature review  

PubMed Central

Background There is as yet limited evidence about fertility-sparing surgery for early ovarian cancer (EOC) carried out laparoscopically. We sought to analyze recurrence patterns and fertility outcome in a cohort of ovarian cancer patients who underwent fertility-saving laparoscopic surgical staging. Methods We conducted a retrospective analysis of prospectively collected data on all patients undergoing fertility-sparing laparoscopic staging procedures for presumed EOC at a single gynecologic oncology service. Oncologic safety and reproductive outcome were the main outcome measures. The pertinent literature is reviewed. Results The study cohort consisted of 12 women. Cases included 5 invasive epithelial tumors and 7 nonepithelial tumors. The disease was reclassified to a higher stage in one woman. After a median follow up period of 38 months (range: 14–108), the overall survival was 100% and recurrence-free survival 90.9%. Five (100%) of patients who attempted pregnancy conceived spontaneously. Three of them had uneventful term pregnancy delivering healthy babies. The literature search yielded 62 cases of laparoscopic fertility conserving surgery for ovarian cancer. There were 4 (6.2%) recurrences. Cumulative pregnancy and live birth rate were not estimable as earlier publications lack essential data. Conclusions Laparoscopic staging may represent a viable option for premenopausal women seeking fertility preservation in the setting of early ovarian cancer. More research is needed to determine whether laparoscopy may offer reproductive benefits to this particular population. PMID:24917888

Associations between cytokine gene variations and severe persistent breast pain in women following breast cancer surgery  

PubMed Central

Persistent pain following breast cancer surgery is a significant clinical problem. While immune mechanisms may play a role in the development and maintenance of persistent pain, few studies have evaluated for associations between persistent breast pain following breast cancer surgery and variations in cytokine genes. In this study, associations between previously identified extreme persistent breast pain phenotypes (i.e., no pain versus severe pain) and single nucleotide polymorphisms (SNPs) spanning 15 cytokine genes were evaluated. In unadjusted analyses, the frequency of 13 SNPs and 3 haplotypes in 7 genes differed significantly between the no pain and severe pain classes. After adjustment for preoperative breast pain and the severity of average postoperative pain, one SNPs (i.e., interleukin (IL) 1 receptor 2 rs11674595) and one haplotype (i.e., IL10 haplotype A8) were associated with pain group membership. These findings suggest a role for cytokine gene polymorphisms in the development of persistent breast pain following breast cancer surgery. Perspective This study evaluated for associations between cytokine gene variations and the severity of persistent breast pain in women following breast cancer surgery. Variations in two cytokine genes were associated with severe breast pain. The results suggest that cytokines play a role in the development of persistent postsurgical pain. PMID:24411993

Reoperation for early postoperative complications after gastric cancer surgery in a Chinese hospital  

PubMed Central

AIM: To investigate the occurrence of postoperative complications of gastric cancer surgery, and analyze the potential causes of reoperation for early postoperative complications. METHODS: A total of 1639 patients who underwent radical or palliative gastrectomies for gastric cancer were included in the study. The study endpoint was the analysis of postoperative complications in inpatients. RESULTS: About 31% of patients had early postoperative complications, and complications of infection occurred most frequently. Intra-abdominal hemorrhage and anastomotic leak were the main causes of reoperation, which accounted for about 2.2%. Mortality was 11.1% in the reoperation group, but was only 0.8% in other patients. The duration of postoperative stay in hospital was significantly longer and the total expenditure was markedly higher in the patients who underwent reoperation (P < 0.001). There was no significant association of any available factors in this study with the high rate of reoperation. CONCLUSION: Reoperation significantly increases the mortality rate and raises the burden of the surgical unit. More prospective studies are required to explore the potential risk factors.

Risk Factors for Major Adverse Events of Video-Assisted Thoracic Surgery Lobectomy for Lung Cancer  

PubMed Central

Aims: The purpose of this study was to identify the risk factors for major adverse events of VATS (Video-Assisted Thoracic Surgery) lobectomy for primary lung cancer. Methods: 1806 Patients (1032 males, 57.1%) planned to undergo VATS lobectomy for stage IA-IIIA lung cancer from July 2007 to June 2012. The Thoracic Morbidity and Mortality Classification TM&M system was used to evaluate the presence and severity of complications. Postoperative complications were observed during a 30-day follow up. Univariate and multivariate analysis were used to analyze the independent risk factors for major adverse events. Results: Successful rate of VATS lobectomy was 97.6% (1763/1806). Major complications occurred in 129 patients (7.3%), with a mortality of 0.3% (5/1763). Pulmonary complications contribute up to 90.7% of the major complications and 80% of mortality. Logistic regression indicated that comorbidities, elder age ?70y, operative time ?240min and hybrid VATS were predictors for major adverse events (P<0.05). Hybrid and converted VATS lobectomy result in higher major adverse events compared with complete VATS, 15.1%, 20.9% and 7.4% respectively (P=0.013). Conclusions: The overall complication rate and mortality of VATS lobectomy are low, while major complications sometimes occur. Pulmonary complications are the most common major complications and cause of mortality. Age ?70y, comorbidities, operative time ?240min and Hybrid VATS are predictors of major adverse events.

Techniques for restoring bowel continuity and function after rectal cancer surgery  

PubMed Central

A very low local recurrence rate of 3%-6% (associated with improved 5 year survival) is possible when proper oncological surgery is performed of mid and distal rectal adenocarcinoma. Restoration of bowel continuity is possible in most cases, without compromise of cancer clearance. Re-anastomosis can be performed with stapled, transabdominal hand-sewn or coloanal pull-through techniques. However after a direct (straight) anastomosis of the colon to the distal rectum/anus, up to 33% of patients have 3 or more bowel movements/d; some can be troubled with up to 14 stools a day. Construction of a 6-cm colonic J-pouch is likely to cause some reversed peristalsis which improves postoperative bowel frequency without causing neo-rectum evacuation problems. Colonic J-pouch-anal anastomosis patients have a median of 3 bowel movements a day compared with a median of 6 a day for straight anastomoses, at 1 year after surgery. In the longer term, bowel adaptation may enable the function after a straight anastomosis to approximate that of a colonic J-pouch-anal anastomosis. This probably depends in the former, upon whether the more rigid sigmoid colon or more distensible descending colon is used. An additional advantage of the colonic J-pouch-anal anastomosis is the lower risk of anastomotic complications. A more vascularized side-to-end (colonic J-pouch-anal) anastomosis is likely to heal better than an end-to-end (straight) anastomosis. Where the pelvis is too narrow for a bulky colonic J-pouch anal anastomosis, a coloplasty-anal-anastomosis is an option. The latter results in postoperative bowel function comparable with the colonic J-pouch. However, the risk of anastomotic complications is higher possibly related to its end-to-end anastomotic configuration. Laparoscopic techniques for accomplishing all the above are being proven to be effective. Restorative surgery for rectal cancer can be safely and effectively performed with methods to improve bowel function very acceptably; the future advances are likely in laparoscopy. PMID:17072945

Surgical site infections following colorectal cancer surgery: a randomized prospective trial comparing common and advanced antimicrobial dressing containing ionic silver  

PubMed Central

Background An antimicrobial dressing containing ionic silver was found effective in reducing surgical-site infection in a preliminary study of colorectal cancer elective surgery. We decided to test this finding in a randomized, double-blind trial. Methods Adults undergoing elective colorectal cancer surgery at two university-affiliated hospitals were randomly assigned to have the surgical incision dressed with Aquacel® Ag Hydrofiber dressing or a common dressing. To blind the patient and the nursing and medical staff to the nature of the dressing used, scrub nurses covered Aquacel® Ag Hydrofiber with a common wound dressing in the experimental arm, whereas a double common dressing was applied to patients of control group. The primary end-point of the study was the occurrence of any surgical-site infection within 30?days of surgery. Results A total of 112 patients (58 in the experimental arm and 54 in the control group) qualified for primary end-point analysis. The characteristics of the patient population and their surgical procedures were similar. The overall rate of surgical-site infection was lower in the experimental group (11.1% center 1, 17.5% center 2; overall 15.5%) than in controls (14.3% center 1, 24.2% center 2, overall 20.4%), but the observed difference was not statistically significant (P?=?0.451), even with respect to surgical-site infection grade 1 (superficial) versus grades 2 and 3, or grade 1 and 2 versus grade 3. Conclusions This randomized trial did not confirm a statistically significant superiority of Aquacel® Ag Hydrofiber dressing in reducing surgical-site infection after elective colorectal cancer surgery.

Association between Reduction of Plasma Adiponectin Levels and Risk of Bacterial Infection after Gastric Cancer Surgery  

PubMed Central

Background and Purpose Infections are important causes of postoperative morbidity after gastric surgery; currently, no factors have been identified that can predict postoperative infection. Adiponectin (ADN) mediates energy metabolism and functions as an immunomodulator. Perioperative ADN levels and perioperative immune functioning could be mutually related. Here we evaluated a potential biological marker to reliably predict the incidence of postoperative infections to prevent such comorbidities. Methods We analyzed 150 consecutive patients who underwent elective gastric cancer surgery at the Shiga University of Medical Science Hospital (Shiga, Japan) from 1997 to 2009; of these, most surgeries (n?=?100) were performed 2008 onwards. The patient characteristics and surgery-related factors between two groups (with and without infection) were compared by the paired t-test and ?2 test, including preoperative ADN levels, postoperative day 1 ADN levels, and ADN ratio (postoperative ADN levels/preoperative ADN levels) as baseline factors. Logistic regression analysis was performed to access the independent association between ADN ratio and postoperative infection. Finally, receiver operating curves (ROCs) were constructed to examine its clinical utility. Results Sixty patients (40%) experienced postoperative infections. The baseline values of age, American Society of Anesthesiologists physical status, total operating time, blood loss, surgical procedure, C-reactive protein (CRP) levels, preoperative ADN levels, and ADN ratio were significantly different between groups. Logistic regression analysis using these factors indicated that type 2 diabetes mellitus (T2DM) and ADN ratio were significantly independent variables (*p<0.05, ** p<0.01, respectively). ROC analysis revealed that the useful cutoff values (sensitivity/specificity) for preoperative ADN levels, ADN ratio, blood loss, operating time, and CRP levels were 8.81(0.567/0.568), 0.76 (0.767/0.761), 405 g (0.717/0.693), 342 min (0.617/0.614), and 8.94 mg/dl (0.583/0.591), respectively. Conclusion T2DM and ADN ratio were independent predictors of postoperative infection and ADN ratio was the most useful predictor for postoperative infection. PMID:23520452

Risk factors and operative mortality in surgery for colorectal cancer.  

PubMed Central

The operative mortality rate after surgery for colorectal carcinoma remains significant. A series of 578 patients has been studied prospectively. The features which most significantly affect operative mortality are the age of the patient, a history of loss of weight, limited preoperative patient mobility and the presence of intestinal obstruction with perforation of the bowel. By identifying high-risk groups of patients, attention may be focused on particular patients at risk, in order to reduce operative mortality. PMID:1929123

Surgery Triggers Outgrowth of Latent Distant Disease in Breast Cancer: An Inconvenient Truth?  

PubMed Central

We review our work over the past 14 years that began when we were first confronted with bimodal relapse patterns in two breast cancer databases from different countries. These data were unexplainable with the accepted continuous tumor growth paradigm. To explain these data, we proposed that metastatic breast cancer growth commonly includes periods of temporary dormancy at both the single cell phase and the avascular micrometastasis phase. We also suggested that surgery to remove the primary tumor often terminates dormancy resulting in accelerated relapses. These iatrogenic events are apparently very common in that over half of all metastatic relapses progress in that manner. Assuming this is true, there should be ample and clear evidence in clinical data. We review here the breast cancer paradigm from a variety of historical, clinical, and scientific perspectives and consider how dormancy and surgery-driven escape from dormancy would be observed and what this would mean. Dormancy can be identified in these diverse data but most conspicuous is the sudden synchronized escape from dormancy following primary surgery. On the basis of our findings, we suggest a new paradigm for early stage breast cancer. We also suggest a new treatment that is meant to stabilize and preserve dormancy rather than attempt to kill all cancer cells as is the present strategy. PMID:24281072

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

Benefits versus risks in conservation surgery with irradiation for breast cancer  

SciTech Connect

This report analyzes the survival and complications inherent in the conventional treatment of breast cancer, radical mastectomy, and the more conservative procedure, conservation surgery with irradiation. Both procedures have benefits and risks. The benefits as measured by survivorship appear to be approximately the same. The major benefit of conservation surgery with irradiation is that the breast is left intact. The possible complication of irradiation carcinogenesis is addressed, and the literature analyzed. This review indicates that the absolute risk of breast cancer developing in the second breast is not nearly as great as originally thought. It is concluded that if a woman with breast cancer is a candidate for either mastectomy or the conservative procedure, it is the clinician's obligation to objectively present the evidence regarding the benefits and risks of these procedures.

Uptake of an innovation in surgery: observations from the cluster-randomized Quality Initiative in Rectal Cancer trial  

PubMed Central

Background Theory suggests the uptake of a medical innovation is influenced by how potential adopters perceive innovation characteristics and by characteristics of potential adopters. Innovation adoption is slow among the first 20% of individuals in a target group and then accelerates. The Quality Initiative in Rectal Cancer (QIRC) trial assessed if rectal cancer surgery outcomes could be improved through surgeon participation in the QIRC strategy. We tested if traditional uptake of innovation concepts applied to surgeons in the experimental arm of the trial. Methods The QIRC strategy included workshops, access to opinion leaders, intra-operative demonstrations, postoperative questionnaires, and audit and feedback. For intraoperative demonstrations, a participating surgeon invited an outside surgeon to demonstrate optimal rectal surgery techniques. We used surgeon timing in a demonstration to differentiate early and late adopters of the QIRC strategy. Surgeons completed surveys on perceptions of the strategy and personal characteristics. Results Nineteen of 56 surgeons (34%) requested an operative demonstration on their first case of rectal surgery. Early and late adopters had similar perceptions of the QIRC strategy and similar characteristics. Late adopters were less likely than early adopters to perceive an advantage for the surgical techniques promoted by the trial (p = 0.023). Conclusion Most traditional diffusion of innovation concepts did not apply to surgeons in the QIRC trial, with the exception of the importance of perceptions of comparative advantage. PMID:24284150

Conservative surgery in early-stage cervical cancer: what percentage of patients may be eligible for conization and lymphadenectomy?  

PubMed Central

Objective To determine the proportion of young patients with early-stage invasive cervical cancer treated with radical hysterectomy who may have been eligible for fertility-sparing surgery consisting of cervical conization with pelvic lymph node dissection. Methods We retrospectively identified all patients with early-stage cervical cancer (stage IA2-IB1) who underwent a radical hysterectomy at The University of Texas M. D. Anderson Cancer Center between 1990 and 2009. We reviewed these patients’ records to identify patients who were < 40 years who had not previously undergone tubal ligation and who would have been considered candidates for cold-knife conization with pelvic lymph node dissection—i.e., women with tumors smaller than 2 cm, low-risk histology (squamous, adenocarcinoma, or adenosquamous), and no lymphovascular space invasion (LVSI). Results A total of 507 patients with early-stage cervical cancer were identified who underwent radical hysterectomy during the review period. Of these women, 277 (55%) were 40 years or younger. Of these 277 patients, 75 (27%) had had a previous tubal ligation and 202 (73%) had not. Of these 202 patients potentially interested in fertility preserving surgery, 53 (26%) had favorable pathologic characteristics including low-risk histology, tumors ?2cms in size and no LVSI present. Of these 53 patients, none had parametrial involvement or positive lymph nodes. Conclusion Among 202 women with age younger than 40 years and no previous tubal ligation who underwent radical hysterectomy, 53 (26%) may have been eligible for fertility-sparing surgery such as cold-knife conization with pelvic lymph node dissection.

See-and-treat surgery for facial skin cancer.  

PubMed

See-and-treat surgery has been described as an efficient means of streamlining specialist diagnosis and treatment, and is commonly employed in gynaecology to reduce the delay between cytological screening and definitive treatment of cervical neoplasia. Relatively young patients with predominantly benign skin lesions have been treated in see-and-treat clinics but only in the context of referrals from primary care. The author describes the treatment of tertiary referrals for facial skin malignancies under local anaesthesia at these clinics, and analyses their acceptability to patients. A total of 100 consecutive patients were included. Data on age, coexisting conditions, diagnosis, site and size of lesion, operation, and outcomes including complications and completeness of excision, were collected. A questionnaire seeking patients' opinions was also used. Ninety patients were treated and 98 lesions were removed, 94% of which were malignant. The complete excision rate was 95%. There were no complications, and 98% of patients were satisfied with the service. See-and-treat surgery is an effective, safe, and acceptable means of providing surgical management of facial skin malignancies. PMID:24927655

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.

Hereditary diffuse gastric cancer: implications of genetic testing for screening and prophylactic surgery.  

PubMed

Approximately 10% of patients with gastric cancer show familial clustering, and 3% show autosomal dominance and high penetrance. Hereditary diffuse gastric cancer (HDGC) is an autosomal-dominant, inherited cancer syndrome in which affected individuals develop diffuse-type gastric cancer at a young age. Inactivating mutations in the E-cadherin gene CDH1 have been identified in 30% to 50% of patients. CDH1 mutation carriers have an approximately 70% lifetime risk of developing DGC, and affected women carry an additional 20% to 40% risk of developing lobular breast cancer. Because endoscopic surveillance is ineffective in identifying early HDGC, gene-directed prophylactic total gastrectomy currently is offered for CDH1 mutation carriers. In series of asymptomatic individuals undergoing total gastrectomy for CDH1 mutations, the removed stomachs usually contain small foci of early DGC, making surgery not prophylactic but curative. The authors of this review recommend consideration of total gastrectomy in CDH1 mutation carriers at an age 5 years younger than the youngest family member who developed gastric cancer. Individuals who choose not to undergo prophylactic gastrectomy should be followed with biannual chromoendoscopy, and women with CDH1 mutations also should undergo regular surveillance with magnetic resonance imaging studies of the breast. Because of the emergence of gene-directed gastrectomy for HDGC, today, a previously lethal disease is detected by molecular techniques, allowing curative surgery at an early stage. PMID:18798546

A Methylene Blue–assisted Technique for Harvesting Lymph Nodes After Radical Surgery for Gastric Cancer  

PubMed Central

Harvesting lymph nodes (LNs) after gastrectomy is essential for accurate staging. This trial evaluated the efficiency and quality of a conventional method and a methylene blue–assisted method in a randomized manner. The key eligibility criteria were as follows: (i) histologically proven adenocarcinoma of the stomach; (ii) clinical stage I-III; (iii) R0 resection planned by gastrectomy with D1+ or D2 lymphadenectomy. The primary endpoint was the ratio of the pathologic number of harvested LNs per time (minutes) as an efficacy measure. The secondary endpoint was the number of harvested LNs, as a quality measure. Between August 2012 and December 2012, 60 patients were assigned to undergo treatment using the conventional method (n=29) and the methylene blue dye method (n=31). The baseline demographics were mostly well balanced between the 2 groups. The number of harvested LNs (mean±SD) was 33.6±11.9 in the conventional arm and 43.4±13.9 in the methylene blue arm (P=0.005). The ratio of the number of the harvested LNs per time was 1.12±0.46 LNs/min in the conventional arm and 1.49±0.59 LNs/min in the methylene blue arm (P=0.010). In the subgroup analyses, the quality and efficacy were both superior for the methylene blue dye method compared with the conventional method. The methylene blue technique is recommended for harvesting LNs during gastric cancer surgery on the basis of both the quality and efficacy. PMID:25356528

Long-term survival of young women receiving fertility-sparing surgery for ovarian cancer in comparison with those undergoing radical surgery  

PubMed Central

Objectives: To compare the clinical outcome of patients with stage I epithelial ovarian cancer (EOC) who received with fertility-sparing surgery (FSS) with those who underwent radical surgery (RS). Methods: After a central pathological review and search of the medical records from multiple institutions, a total of 572 patients were retrospectively evaluated. All patients were divided into three groups: group A {FSS (n=74); age, ?40} groups B and C [RS; age, 40?{(B), n=52} 40<{(C), n=446}]. Results: Five-year overall survival (OS) and disease-free survival (DFS) rates of patients in the groups were as follows: group A, 90.8% (OS)/87.9% (DFS); group B, 88.3% (OS)/84.4% (DFS); group C, 90.6% (OS)/85.3% (DFS), respectively (OS, P=0.802; DFS, P=0.765). Additionally, there was no significant difference in OS and DFS among the three groups stratified to stage IA or IC (OS (IA), P=0.387; DFS (IA), P=0.314; OS (IC), P=0.993; DFS (IC), P=0.990, respectively). Furthermore, patients with a grade 1–2 or 3 tumours in the FSS group did not have a poorer prognosis than those in the RS group. Conclusions: Stage I EOC patients treated with FSS showed an acceptable prognosis compared with those who underwent RS. PMID:21970882

Patients’ Expectations of Functional Outcomes Following Rectal Cancer Surgery: a Qualitative Study  

PubMed Central

Background Rectal cancer patients’ expectations of health and function may affect their disease- and treatment-related experience, but how patients form expectations of post-surgery function has received little study. Objective We used a qualitative approach to explore patients’ expectations of outcomes related to bowel function following sphincter-preserving surgery (SPS) for rectal cancer. Design and Setting Individual telephone interviews with patients who were about to undergo SPS for rectal cancer. Patients 26 patients (14 men, 12 women) with clinical stage (cTNM) I to III disease. Main Outcome Measures The semi-structured interview script contained open-ended questions on patients’ expectations of post-operative bowel function and its perceived impact on daily function and life. Two researchers analyzed the interview transcripts for emergent themes using a grounded theory approach. Results Participants’ expectations of bowel function reflected three major themes: (1) information sources, (2) personal attitudes, and (3) expected outcomes. The expected outcomes theme contained references to specific symptoms and participants’ descriptions of the certainty, importance and imminence of expected outcomes. Despite multiple information sources and attempts at maintaining a positive personal attitude, participants expressed much uncertainty about their long term bowel function. They were more focused on what they considered more important and imminent concerns about being cancer-free and getting through surgery. Limitations This study is limited by context in terms of the timing of interviews (relative to the treatment course). The transferability to other contexts requires further study. Conclusions Patients’ expectations of long term functional outcomes cannot be considered outside of the overall context of the cancer-experience and the relative importance and imminence of cancer- and treatment-related events. Recognizing the complexities of the expectation formation process offers opportunities to develop strategies to enhance patient education and appropriately manage expectations, attend to immediate and long term concerns, and support patients through the treatment and recovery process.

Anastomotic leakage after colorectal cancer surgery: a risk factor for recurrence and poor prognosis.  

PubMed

In order to discover the incidence of recurrence and prognosis of patients with anastomotic leakage after colorectal surgery, 980 colorectal cancer patients who underwent anastomosis at Keio University Hospital between 1970 and 1990 were examined. Thirty-three patients (leakage group) out of the 980 exhibited anastomotic leakage. The incidence of local recurrence in the leakage group was significantly higher than in the no leakage group (P < 0.01). The disease-free survival rate of the leakage group was significantly lower than that of the no leakage group in Dukes' A, B patients (P < 0.01), but was not so in Dukes' C, D patients. These results suggested that anastomotic leakage after colorectal cancer surgery might enhance the incidence of local recurrence and make the prognosis poor. PMID:8230754

Current status of robotic surgery for rectal cancer: A bird's eye view  

PubMed Central

Minimally invasive surgery for rectal cancer is now widely performed via the laparoscopic approach and has been validated in randomized controlled trials to be oncologically safe with better perioperative outcomes than open surgery including shorter length of stay, earlier return of bowel function, better cosmesis, and less analgesic requirement. Laparoscopic surgery, however, has inherent limitations due to two-dimensional vision, restricted instrument motion and a very long learning curve. Robotic surgery with its superb three-dimensional magnified optics, stable retraction platform and 7 degrees of freedom of instrument movement offers significant benefits during Total Mesorectal Excision (TME) including ease of operation, markedly lower conversion rates and better quality of the specimen in addition to shorter (steeper) learning curves. This review summarizes the current evidence for the adoption of robotic TME for rectal cancer with supporting data from the literature and from the authors’ own experience. All relevant articles from PubMed using the search terms listed below and published between 2000 and 2014 including randomized trials, meta-analyses, prospective studies, and retrospective reviews with substantial numbers were included.

Selection criteria for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in gastric cancer.  

PubMed

Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis. Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier. Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients. Patient selection for this multimodal approach is one of the most critical issues, and calls for interdisciplinary evaluation by radiologists, medical and surgical oncologists, and anaesthetists. This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis. PMID:22072845

Minimally invasive concomitant aortic and mitral valve surgery: the “Miami Method  

PubMed Central

Valve surgery via a median sternotomy has historically been the standard of care, but in the past decade various minimally invasive approaches have gained increasing acceptance. Most data available on minimally invasive valve surgery has generally involved single valve surgery. Therefore, robust data addressing surgical techniques in patients undergoing double valve surgery is lacking. For patients undergoing combined aortic and mitral valve surgery, a minimally invasive approach, performed via a right lateral thoracotomy (the “Miami Method”), is the preferred method at our institution. This method is safe and effective and leads to an enhanced recovery in our patients given the reduction in surgical trauma. The following perspective details our surgical approach, concepts and results for combined aortic and mitral valve surgery.

A randomised phase III trial comparing gemcitabine with surgery-only in patients with resected pancreatic cancer: Japanese Study Group of Adjuvant Therapy for Pancreatic Cancer  

PubMed Central

Background: This multicentre randomised phase III trial was designed to determine whether adjuvant chemotherapy with gemcitabine improves the outcomes of patients with resected pancreatic cancer. Methods: Eligibility criteria included macroscopically curative resection of invasive ductal carcinoma of the pancreas and no earlier radiation or chemotherapy. Patients were randomly assigned at a 1?:?1 ratio to either the gemcitabine group or the surgery-only group. Patients assigned to the gemcitabine group received gemcitabine at a dose of 1000?mg?m?2 over 30?min on days 1, 8 and 15, every 4 weeks for 3 cycles. Results: Between April 2002 and March 2005, 119 patients were enrolled in this study. Among them, 118 were eligible and analysable (58 in the gemcitabine group and 60 in the surgery-only group). Both groups were well balanced in terms of baseline characteristics. Although heamatological toxicity was frequently observed in the gemcitabine group, most toxicities were transient, and grade 3 or 4 non-heamatological toxicity was rare. Patients in the gemcitabine group showed significantly longer disease-free survival (DFS) than those in the surgery-only group (median DFS, 11.4versus 5.0 months; hazard ratio=0.60 (95% confidence interval (CI): 0.40–0.89); P=0.01), although overall survival did not differ significantly between the gemcitabine and surgery-only groups (median overall survival, 22.3 versus 18.4 months; hazard ratio=0.77 (95% CI: 0.51–1.14); P=0.19). Conclusion: The current results suggest that adjuvant gemcitabine contributes to prolonged DFS in patients undergoing macroscopically curative resection of pancreatic cancer. PMID:19690548

Measuring decision quality: psychometric evaluation of a new instrument for breast cancer surgery  

PubMed Central

Background The purpose of this paper is to examine the acceptability, feasibility, reliability and validity of a new decision quality instrument that assesses the extent to which patients are informed and receive treatments that match their goals. Methods Cross-sectional mail survey of recent breast cancer survivors, providers and healthy controls and a retest survey of survivors. The decision quality instrument includes knowledge questions and a set of goals, and results in two scores: a breast cancer surgery knowledge score and a concordance score, which reflects the percentage of patients who received treatments that match their goals. Hypotheses related to acceptability, feasibility, discriminant validity, content validity, predictive validity and retest reliability of the survey instrument were examined. Results We had responses from 440 eligible patients, 88 providers and 35 healthy controls. The decision quality instrument was feasible to implement in this study, with low missing data. The knowledge score had good retest reliability (intraclass correlation coefficient?=?0.70) and discriminated between providers and patients (mean difference 35%, p?

Down-staging following neoadjuvant chemo-radiotherapy for locally advanced rectal cancer: Does timing of surgery really matter?  

PubMed Central

Background: Neoadjuvant chemoradiotherapy (NACTRT) improves local recurrence rate in locally advanced (LA) rectal cancer with no survival benefit. Pathological complete response (pCR) post-NACTRT is associated with improved outcome. Debate is ongoing as to when would be the opportune time to operate. Aim: To determine if greater down-staging can be achieved by a longer time interval from NACTRT to surgery (tumor regression score [TRS]) and whether this would impact sphincter saving surgery rates and early relapse rates. Materials and Methods: A retrospective analysis of a prospectively maintained database of patients with LA rectal adenocarcinoma treated from January 2012 to August 2013 was carried out. One hundred and ten patients who completed NACTRT (50 Gy/25 fractions with capecitabine 825 mg/m2 twice daily) followed by surgical resection were included. For response evaluation patients were divided into two groups, Group 1 (TRS ?60 days, n = 42) and 2 (TRS >60 days, n = 68). Tumor down-staging, pCR rate, tumor regression grade (TRG) post-NACTRT and relapse rates were correlated with TRS. Results: Of 110 patients (median age: 49 years (21-73), 71% males; 18 (16.5%) with signet ring histology) 96% patients underwent an R0 resection. Post-NACTRT, CR was attained in 5 (4.5%), partial response in 98 (89%) and stable disease in 7 (6.4%) patients. Median time from completion of NACTRT to surgery was 64.5 days (6-474). Median lymph nodes harvested were 10 (1-50). Overall, 22 (20%) patients achieved pCR. 26 (62%) patients in Group 1 compared to 36 (53%) in Group 2 underwent sphincter sparing surgery (SSS) (P = 0.357). Six patients (14%) in Group 1 and 16 (24%) in Group 2 achieved pCR (P = 0.24). Median TRG in both groups was three. Conclusion: Timing of surgery following NACTRT for LA rectal cancer does not influence pathological response, ability to perform SSS or disease-free survival. There is no incremental benefit of delaying the surgery though this needs to be confirmed in a prospective randomized trial.

Asymptomatic gallstones. What to do in patients undergoing colonic surgery for cancer?  

PubMed

Twenty-three patients who underwent elective surgery for colorectal cancer in our hospital between 1983 and 1989, underwent concomitant cholecystectomy for asymptomatic gallstones. In order to assess whether additional cholecystectomy increases postoperative morbidity and mortality, a comparison was made between these cases and 23 controlled patients (without gallstones) matched for sex, age (+/- 3 years), Dukes stage and type of primary colonic surgery. The duration of postoperative stay was similar in the two groups (14.1 +/- 4.5 days vs 12.4 +/- 2.3 days). Postoperative complications were more frequent among the case patients than among the controls (34.8% vs 8.7%, p = 0.04), and the same was true for the mortality (8.7% vs 0%). During the same period, another 11 patients with asymptomatic cholelithiasis were operated on for colorectal cancer but in these patients gallstones were left in place. Two of the patients died postoperatively and only one of the remaining 9 (11.2%) had an episode of biliary pain. The results of our study would suggest that in patients undergoing surgery for colorectal cancer the risk entailed in carrying out an additional cholecystectomy for asymptomatic gallstones is greater than the risk of future morbidity caused by gallstones left in place.

Breast cancer surgery and diagnosis-related groups (DRGs): patient classification and hospital reimbursement in 11 European countries.  

PubMed

Researchers from eleven countries (i.e. Austria, England, Estonia, Finland, France, Germany, Ireland, Netherlands, Poland, Spain, and Sweden) compared how their DRG systems deal with breast cancer surgery patients. DRG algorithms and indicators of resource consumption were assessed for those DRGs that individually contain at least 1% of all breast cancer surgery patients. Six standardised case vignettes were defined and quasi prices according to national DRG-based hospital payment systems were ascertained. European DRG systems classify breast cancer surgery patients according to different sets of classification variables into three to seven DRGs. Quasi prices for an index case treated with partial mastectomy range from €577 in Poland to €5780 in the Netherlands. Countries award their highest payments for very different kinds of patients. Breast cancer specialists and national DRG authorities should consider how other countries' DRG systems classify breast cancer patients in order to identify potential scope for improvement and to ensure fair and appropriate reimbursement.

Lactation following conservation surgery and radiotherapy for breast cancer  

SciTech Connect

A 38-year-old woman with early stage invasive breast cancer was treated with wide excision of the tumor, axillary lymph node dissection, and breast irradiation. Three years later, she gave birth to a normal baby. She attempted breast feeding and had full lactation from the untreated breast. The irradiated breast underwent only minor changes during pregnancy and postpartum but produced small amounts of colostrum and milk for 2 weeks postpartum. There are only a few reports of lactation after breast irradiation. These cases are reviewed, and possible factors affecting breast function after radiotherapy are discussed. Because of scant information available regarding its safety for the infant, nursing from the irradiated breast is not recommended.

Outcome of transoral robotic surgery for stage I-II oropharyngeal cancer.  

PubMed

Traditionally T1-2N0 oropharyngeal carcinoma is treated with a single treatment modality, being either radiotherapy or surgery. Currently, minimally invasive surgery, such as transoral robotic surgery (TORS), is gaining popularity. The aim of this study is to assess whether T1-2N0 oropharyngeal cancer can be safely and effectively resected with TORS, and to determine the oncologic and functional outcomes. In addition, the long-term quality-of-life outcomes are reported. Between 2007 and 2012, 18 patients with early stage oropharyngeal cancers underwent transoral resection with the da Vinci robot system in the Netherlands Cancer Institute. All surviving patients filled out the self-report assessments of quality-of-life questionnaires. Median robot-assisted operating time was 115 min (range 43-186 min), while median estimated blood loss was 5 ml (range 0-125 ml). In three cases the exposure was insufficient to obtain clear tumor margins because of tumor extension and local anatomy. Fourteen patients had clear surgical margins. Four patients received adjuvant radiotherapy. Nine patients underwent an elective unilateral neck dissection. The oropharyngeal cancer recurred in two patients. Regarding the quality of life, patients who needed postoperative radiotherapy had a worse outcome and patients treated with transoral resection only did quite well. TORS seems to be an oncologically safe surgical treatment for early stage T1-2N0 oropharyngeal cancer based on this relatively small group of patients. Selecting patients in whom sufficient surgical exposure can be obtained, should be performed with the greatest care to avoid the need for adjuvant radiotherapy. Comparing radiotherapy and TORS or CO2 laser should be the next step in finding the optimal treatment for patients with T1-2N0 oropharyngeal carcinoma. PMID:24609641

Stereotactic Body Radiotherapy (SBRT) for Operable Stage I Non-Small-Cell Lung Cancer: Can SBRT Be Comparable to Surgery?  

SciTech Connect

Purpose: To review treatment outcomes for stereotactic body radiotherapy (SBRT) in medically operable patients with Stage I non-small-cell lung cancer (NSCLC), using a Japanese multi-institutional database. Patients and Methods: Between 1995 and 2004, a total of 87 patients with Stage I NSCLC (median age, 74 years; T1N0M0, n = 65; T2N0M0, n = 22) who were medically operable but refused surgery were treated using SBRT alone in 14 institutions. Stereotactic three-dimensional treatment was performed using noncoplanar dynamic arcs or multiple static ports. Total dose was 45-72.5 Gy at the isocenter, administered in 3-10 fractions. Median calculated biological effective dose was 116 Gy (range, 100-141 Gy). Data were collected and analyzed retrospectively. Results: During follow-up (median, 55 months), cumulative local control rates for T1 and T2 tumors at 5 years after SBRT were 92% and 73%, respectively. Pulmonary complications above Grade 2 arose in 1 patient (1.1%). Five-year overall survival rates for Stage IA and IB subgroups were 72% and 62%, respectively. One patient who developed local recurrences safely underwent salvage surgery. Conclusion: Stereotactic body radiotherapy is safe and promising as a radical treatment for operable Stage I NSCLC. The survival rate for SBRT is potentially comparable to that for surgery.

A prospective study of conservative surgery without radiation therapy in select patients with Stage I breast cancer  

SciTech Connect

Purpose: The effectiveness of radiation therapy (RT) in reducing local recurrence after breast-conserving surgery (BCS) in unselected patients with early stage invasive breast cancer has been demonstrated in multiple randomized trials. Whether a subset of women can achieve local control without RT is unknown. In 1986, we initiated a prospective one-arm trial of BCS alone for highly selected breast-cancer patients. This report updates those results. Methods and Materials: Eighty-seven (of 90 planned) patients enrolled from 1986 until closure in 1992, when a predefined stopping boundary was crossed. Patients were required to have a unicentric, T1, pathologic node-negative invasive ductal, mucinous, or tubular carcinoma without an extensive intraductal component or lymphatic-vessel invasion. Surgery included local excision with margins of at least 1 cm or a negative re-excision. No RT or systemic therapy was given. Results: Results are available on 81 patients (median follow-up, 86 months). Nineteen patients (23%) had local recurrence (LR) as a first site of failure (average annual LR: 3.5 per 100 patient-years of follow-up). Other sites of first failure included 1 ipsilateral axilla, 2 contralateral breast cancers, and 4 distant metastases. Six patients developed other (nonbreast) malignancies. Nine patients have died, 4 of metastatic breast cancer and 5 of unrelated causes. Conclusions: Even in this highly selected cohort, a substantial risk of local recurrence occurred after BCS alone with margins of 1.0 cm or more. These results suggest that with the possible exception of elderly women with comorbid conditions, radiation therapy after BCS remains standard treatment.

Better Long-Term Survival in Young Patients with Non-Metastatic Colorectal Cancer after Surgery, an Analysis of 69,835 Patients in SEER Database  

PubMed Central

Objective To compare the long-term survival of colorectal cancer (CRC) in young patients with elderly ones. Methods Using Surveillance, Epidemiology, and End Results (SEER) population-based data, we identified 69,835 patients with non-metastatic colorectal cancer diagnosed between January 1, 1988 and December 31, 2003 treated with surgery. Patients were divided into young (40 years and under) and elderly groups (over 40 years of age). Five-year cancer specific survival data were obtained. Kaplan-Meier methods were adopted and multivariable Cox regression models were built for the analysis of long-term survival outcomes and risk factors. Results Young patients showed significantly higher pathological grading (p<0.001), more cases of mucinous and signet-ring histological type (p<0.001), later AJCC stage (p<0.001), more lymph nodes (?12 nodes) dissected (p<0.001) and higher metastatic lymph node ratio (p<0.001). The 5-year colorectal cancer specific survival rates were 78.6% in young group and 75.3% in elderly group, which had significant difference in both univariate and multivariate analysis (P<0.001). Further analysis showed this significant difference only existed in stage II and III patients. Conclusions Compared with elderly patients, young patients with colorectal cancer treated with surgery appear to have unique characteristics and a higher cancer specific survival rate although they presented with higher proportions of unfavorable biological behavior as well as advanced stage disease.

In Vivo Cancer Targeting and Imaging-Guided Surgery with Near Infrared-Emitting Quantum Dot Bioconjugates  

PubMed Central

Early detection and subsequent complete surgical resection are among the most efficient methods for treating cancer. However, low detection sensitivity and incomplete tumor resection are two challenging issues. Nanoparticle-based imaging-guided surgery has proven promising for cancer-targeted imaging and subsequent debulking surgery. Particularly, the use of near infrared (NIR) fluorescent probes such as NIR quantum dots (QDs) allows deep penetration and high sensitivity for tumor detection. In this study, NIR-emitting CdTe QDs (maximum fluorescence emission peak at 728 nm) were synthesized with a high quantum yield (QY) of 38%. The tumor-specific QD bioconjugates were obtained by attaching cyclic Arg-Gly-Asp peptide (cRGD) to the surface of synthesized QDs, and then injected into U87 MG tumor-bearing mice via tail veins for tumor-targeted imaging. The tumor and its margins were visualized and distinguished by NIR QD bioconjugates, and tumor resection was successfully accomplished via NIR guidance using a Fluobeam-700 NIR imaging system. Our work indicates that the synthesized tumor-specific NIR QDs hold great promise as a potential fluorescent indicator for intraoperative tumor imaging. PMID:22916076

Video-assisted mediastinoscopic resection compared with video-assisted thoracoscopic surgery in patients with esophageal cancer  

PubMed Central

Objective The purpose of this study was to explore the indications of radical vedio-assisted mediastinoscopic resection for esophageal cancer. Methods The data of 109 patients with T1 esophageal cancer who underwent video-assisted mediastinoscopic resection (VAMS group) in Third Affiliated Hospital of Soochow University Hospital from December 2005 to December 2011 were collected in the study for comparison with the 58 patients with T1 esophageal cancer who underwent video-assisted thoracoscopic surgery (VATS group) in Zhongshan Hospital, Fudan University. The perioperative safety and survival were compared between the two groups. Results All operations were successful in both groups. One perioperative death was noted in the VATS group. The incidences of post-operative complications were not significantly different between these two groups, whereas the VAMS group was favorable in terms of operative time (P<0.001) and blood loss (P<0.001), and a significantly larger number of chest lymph nodes were dissected in the VATS group compared with the VAMS group (P<0.001). Long-term follow-up showed that the overall survival was not significantly different between these two groups (P=0.876). Conclusions T1N0M0 esophageal cancer can be as the indication of VAMS radical resection. VAMS radical resection can be considered as the preferred option for patients with poor pulmonary and cardiac function or a history of pleural disease. PMID:24976988

[Radical cancer surgery of renal cell and prostate carcinoma with hematogenous metastasis: benefits].  

PubMed

The therapeutic role of cytoreductive surgery for urogenital malignancies is controversially discussed in the literature. The current article critically reflects the potential impact of cytoreductive surgery in patients with renal cell cancer and prostate cancer with locoregional lymph node or systemic metastases based on a review of the literature and personal experience.Even in the era of molecular targeted therapies in metastatic renal cell cancer, cytoreductive radical nephrectomy seems to exert survival benefit when compared to systemic therapy alone if (1) patients demonstrate a good ECOG performance status, (2) exhibit good or intermediate prognosis according to the Heng criteria, (3) cerebral metastases have been excluded, and (4) >90% of the total cancer volume can be eliminated. Preliminary clinical studies suggest that neoadjuvant systemic treatment might be associated with a significantly reduced 1-year mortality rate.For prostate cancer cytoreductive radical prostatectomy is one of the guideline-recommended treatment options for men with intrapelvic lymph node metastases resulting in survival benefit when compared to androgen deprivation as monotherapy. Cytoreductive radical prostatectomy should be performed (1) in the presence of limited intrapelvic lymph node metastasis without bulky disease, (2) if complete resectability of the primary cancer and its metastasis can be achieved by extended radical prostatectomy and extended pelvic lymphadenectomy, (3) if the patient is included in a multimodality approach, and (4) if the life expectancy is > 10 years.The role of cytoreductive radical prostatectomy in men with osseous metastases remains unclear due to the lack of large clinical trials. Despite the presence of the first promising studies, it is not justified to perform cytoreductive radical prostatectomy outside clinical trials. Preliminary results from small studies indicate that patients with minimal metastatic burden, PSA decrease < 1.0 ng/ml following neoadjuvant ADT for 6 months and complete resectability of the tumor exhibit the best prognosis to benefit from this new surgical approach.

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.

Intraoperative radiation exposure with the use of (18)F-FDG-guided thyroid cancer surgery.  

PubMed

Radio-guided surgery is an established means for surgeons to identify a target of interest for biopsy or excision. This technique is used for a variety of malignancies as well as minimally invasive parathyroid surgery. The primary radionuclide used for these procedures is technetium-99m (Tc-99m), but others have been used. Use of (18)fluorine-fluorodeoxyglucose ((18)F-FDG) in oncology has proliferated. This has created the opportunity to use (18)F-FDG as a potential radio tracer in the operating room. A pilot study of three patients with non-iodine avid thyroid cancers undergoing (18)F-FDG-guided revision thyroid cancer surgery is reported. Radiation exposure to operating room personnel was measured. Radiation exposure to the surgeon and staff members of an operating room is well below the limits of the National Regulatory Commission. Therefore, utilization of this radiopharmaceutical intraoperatively should not be limited in the future because of concern regarding exposure of operating room personnel to radiation. PMID:20115989

[Assessment of respiratory function in the qualification for lung cancer surgery].  

PubMed

Surgery is the treatment of choice in patients with a diagnosis of non-small cell lung cancer (NSCLC). A pivotal of eligibility for resection is the early stage of the disease and histopathological assessment. The performance status and comorbidities in population, predominated by elderly patients, also influence the therapeutic decisions. In some lung cancer patients COPD coexists, characterized by a decrease in lung function. Then the preoperative evaluation is particularly important, for both the risk of postoperative complications, lung function and quality of life postoperatively. Recently several recommendations for preoperative evaluation of patients being considered for surgery were published. The guidelines of BTS (2001, 2010), ACCP (2007, 2013) and joint recommendations of ERS and ESTS (2009) have been based on the currently available research results, and indicated the algorithms. The recommendations ERS/ESTS and ACCP distinguished cardiac risk estimation in all patients, which should precede the evaluation of lung function. According to the latest recommendations (ACCP 2013) the next step is spirometry, DLCO measurement and calculation of predicted postoperative values for both parameters. The low-technology exercise tests (stair climbing, shuttle walk test) were assigned as valuable to discriminate patients at low and intermediate perioperative risk. The cardiopulmonary exercise test (CPET) is recommended to be performed at the final qualification for surgery in patients with high risk. It was also stressed that therapeutic decisions should be taken multidisciplinary, allowing to estimate the risk of complications and to evaluate the expected quality of life in the postoperative time.

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.

Role of breast surgery in T1-3 breast cancer patients with synchronous bone metastases.  

PubMed

The impact of breast surgery on survival of metastatic breast cancer (MBC) patients is controversial. We addressed the question in a mono-institutional series of MBC patients with synchronous bone metastases. We identified 187 consecutive women diagnosed between 2000 and 2008 with locally operable (T1-T3) MBC, synchronous bone metastases, with no other distant sites being involved. Progression-free survival (PFS) and overall survival (OS) were compared between operated and non-operated patients. Median age was 51 years; 92 % of the women had a hormone-positive tumor. At the time of diagnosis, 131 patients out of 187 (70 %) underwent surgery. Operated and non-operated patients differed in terms of number of bone metastatic sites: a single metastasis was detected in 35 (28 %) operated, and 6 (11 %) non-operated cases (P = 0.01). No other significant differences were observed. The multi-adjusted hazard ratio was 0.63 (95 % CI 0.43-0.92) for PFS and 0.64 (95 % CI 0.41-0.99) for OS in favor of surgery. The 5-year cumulative incidence of ipsilateral breast skin progressions among non-operated patients was 18 %. In this large and homogeneous series of MBC patients with synchronous bone metastases, the role of breast surgery had a favorable impact on both disease progression and mortality. PMID:23412771

Which method of pancreatic surgery do medical consumers prefer among open, laparoscopic, or robotic surgery? A survey  

PubMed Central

Purpose The consumers' preferences are not considered in developing or implementing new medical technologies. Furthermore, little efforts are made to investigate their demands. Therefore, their preferred surgical method and the factors affecting that preference were investigated in pancreatic surgery. Methods Six-hundred subjects including 100 medical personnel (MP) and 500 lay persons (LP) were surveyed. Questionnaire included basic information on different methods of distal pancreatectomy; open surgery (OS), laparoscopic surgery (LS), and robotic surgery (RS). Assuming they required the operation, participants were told to indicate their preferred method along with a reason and an acceptable cost for both benign and malignant conditions. Results For benign disease, the most preferred method was LS. Limiting the choice to LS and RS, LS was preferred for cost and well-established safety and efficacy. OS was favored in malignant disease for the concern for radicality. Limiting the choice to LS and RS, LS was favored for its better-established safety and efficacy. The majority thought that LS and RS were both overpriced. Comparing MP and LP responses, both groups preferred LS in benign and OS in malignant conditions. However, LP more than MP tended to prefer RS under both benign and malignant conditions. LP thought that LS was expensive whereas MP thought the cost reasonable. Both groups felt that RS was too expensive. Conclusion Though efforts for development of novel techniques and broadening indication should be encouraged, still more investments and research should focus on LS and OS to provide optimal management and satisfaction to the patients.

The effect of stellate ganglion block on intractable lymphedema after breast cancer surgery.  

PubMed

Lymphedema of the upper limb after breast cancer surgery is a disease that carries a life-long risk and is difficult to cure once it occurs despite the various treatments which have been developed. Two patients were referred from general surgery department for intractable lymphedema. They were treated with stellate ganglion blocks (SGBs), and the circumferences of the mid-point of their each upper and lower arms were measured on every visit to the pain clinic. A decrease of the circumference in each patient was observed starting after the second injection. A series of blocks were established to maintain a prolonged effect. Both patients were satisfied with less swelling and pain. This case demonstrates the benefits of an SGB for intractable upper limb lymphedema. PMID:25589949

Laparoscopic surgery for colon cancer: a review of the fascial composition of the abdominal cavity.  

PubMed

Laparoscopic surgery has generally been performed for digestive diseases. Many patients with colon cancer undergo laparoscopic procedures. The outcomes of laparoscopic colectomy and open colectomy are the same in terms of the long-time survival. It is important to dissect the embryological plane to harvest the lymph nodes and to avoid bleeding during colon cancer surgery. To date, descriptions of the anatomy of the fascial composition have mainly involved observations unrelated to fundamental embryological concepts, causing confusion regarding the explanations of the surgical procedures, with various vocabularies used without definitions. We therefore examined the fascia of the abdominal space using a fascia concept based on clinical anatomy and embryology. Mobilization of the bilateral sides of the colon involves dissection between the fusion fascia of Toldt and the deep subperitoneal fascia. It is important to understand that the right fusion fascia of Toldt is divided into the posterior pancreatic fascia of Treitz dorsally and the anterior pancreatic fascia ventrally at the second portion of the duodenum. A comprehensive understanding of fascia composition between the stomach and transverse colon is necessary for dissecting the splenic flexure of the colon. As a result of these considerations of the fascia, more accurate surgical procedures can be performed for the excision of colon cancer. PMID:24515451

Preoperative intestinal stent decompression with primary laparoscopic surgery to treat left-sided colorectal cancer with obstruction: a report of 21 cases  

PubMed Central

Objective This work aimed to study the safety and efficacy of preoperative intestinal stent decompression combined with laparoscopic surgery to treat left-sided colorectal cancer with obstruction (LCCO). Methods Retrospective analysis was conducted on data obtained from 21 LCCO patients admitted to The First Affiliated Hospital of Zhejiang Chinese Medicine University during March 2008 and December 2011. To remove the intestinal obstruction, preoperative intestinal stent placement under colonoscopic guidance was performed. Approximately 7 to 10 days after the operation, laparoscopic radical surgery of colorectal cancer was conducted. Results Among the 21 cases studied, laparoscopic surgery was successful in 20 patients. Emergent laparotomy was conducted in one patient because of tumor invasion in the ureter. The duration of the operation ranged from 180 to 320 min, and the average time was 220 min. The recovery time for bowel function ranged from 2 to 5 days with an average time of 3 days. Postoperative infection of the incision occurred in one case. No anastomotic leakage was observed in any of the cases. Conclusion Preoperative intestinal stent decompression, combined with primary stage laparoscopic surgery, is a safe and effective method for the treatment of LCCO. PMID:23882425

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.

Fertility sparing surgery for treatment of early-stage cervical cancer: open vs. robotic radical trachelectomy  

PubMed Central

Background To compare the open versus robotic surgical approaches and provide surgical outcome data on patients who have undergone radical trachelectomy (RT). Methods We identified patients who underwent open (ORT) or robotic radical trachelectomy (RRT) between September 2005–June 2011. Tumor characteristics, perioperative, operative and obstetrical outcomes were analyzed. Results Thirty-seven patients with early stage cervical cancer that desired future fertility underwent attempted radical trachelectomy, and 32 patients (20 with 1B1, 11 with 1A2, and 5 with 1A1 with LVSI/poorly differentiated histology) had successful completion of RT. Five (1 open/4 robotic) underwent conversion to radical hysterectomy secondary to close (<5mm) endocervical margin (p=0.08). The median age at diagnosis was 28.9 years (range; 21.4–37.2), 70% were nulliparous, and 9 had a visible lesion. Twenty-five patients (68%) underwent ORT and 12 (32%) underwent RRT. RRT was associated with less blood loss (62.5 mL vs. 300 mL, p=0.0001) and decreased length of postoperative stay (1 vs. 4 days, p<0.001), with no difference in operative time or histopathologic outcomes. Twenty-three patients (62%) had no residual cervical disease on final pathology. Common long-term morbidities were irregular menstrual bleeding or amenorrhea (25%), cerclage erosion (13%), or cervical stenosis (9%). Although there was a higher rate of conversion to hysterectomy in the robotic surgery cohort, rates of serious morbidities among the cohorts were comparable (robotic: 33% vs. open: 24%, p=0.70). Eleven (36%) patients are actively attempting pregnancy and three have achieved pregnancy. The median time of follow up is 17.0 months (range 0.30–64.9 months). There are no documented recurrences. Conclusions RRT results in less blood loss and decreased length of hospital stay with no compromise in histopathologic outcomes. PMID:22035808

Role of Peritoneal Lavage Cytology and Prediction of Prognosis and Peritoneal Recurrence After Curative Surgery for Colorectal Cancer  

PubMed Central

Purpose In colorectal cancer, the role of detecting free malignant cells from peritoneal lavage is currently unclear. In this study, we investigated the positive rate of free malignant cells in peritoneal lavage fluid and their predictive value for prognosis and peritoneal recurrence after a curative resection. Methods From October 2009 to December 2011, in a prospective manner, we performed cytologic examinations of peritoneal lavage fluid obtained just after the abdominal incision from 145 patients who underwent curative surgery for colorectal cancer. We used proportional hazard regression models to analyze the predictive role of positive cytology for peritoneal recurrence and survival. Results Among total 145 patients, six patients (4.1%) showed positive cytology. During the median follow-up of 32 months (range, 8-49 months), 27 patients (18.6%) developed recurrence. Among them, 5 patients (3.4%) showed peritoneal carcinomatosis. In the multivariate analysis, positive cytology was an independent predictive factor for peritoneal recurrence (hazard ratio [HR], 136.5; 95% confidence interval [CI], 12.2-1,531.9; P < 0.0001) and an independent poor prognostic factor for overall survival (HR, 11.4; 95% CI, 1.8-72.0; P = 0.009) and for disease-free survival (HR, 11.1; 95% CI, 3.4-35.8; P < 0.0001). Conclusion Positive cytology of peritoneal fluid was significantly associated with peritoneal recurrence and worse survival in patients undergoing curative surgery for colorectal cancer. Peritoneal cytology might be a useful tool for selecting patients who need intraperitoneal or systemic chemotherapy. PMID:25580413

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

Analysis of laser surgery in non-melanoma skin cancer for optimal tissue removal  

NASA Astrophysics Data System (ADS)

Laser surgery is a commonly used technique for tissue ablation or the resection of malignant tumors. It presents advantages over conventional non-optical ablation techniques, like a scalpel or electrosurgery, such as the increased precision of the resected volume, minimization of scars and shorter recovery periods. Laser surgery is employed in medical branches such as ophthalmology or dermatology. The application of laser surgery requires the optimal adjustment of laser beam parameters, taking into account the particular patient and lesion. In this work we present a predictive tool for tissue resection in biological tissue after laser surgery, which allows an a priori knowledge of the tissue ablation volume, area and depth. The model employs a Monte Carlo 3D approach for optical propagation and a rate equation for plasma-induced ablation. The tool takes into account characteristics of the specific lesion to be ablated, mainly the geometric, optical and ablation properties. It also considers the parameters of the laser beam, such as the radius, spatial profile, pulse width, total delivered energy or wavelength. The predictive tool is applied to dermatology tumor resection, particularly to different types of non-melanoma skin cancer tumors: basocellular carcinoma, squamous cell carcinoma and infiltrative carcinoma. The ablation volume, area and depth are calculated for healthy skin and for each type of tumor as a function of the laser beam parameters. The tool could be used for laser surgery planning before the clinical application. The laser parameters could be adjusted for optimal resection volume, by personalizing the process to the particular patient and lesion.

Adjuvant (post-surgery) chemotherapy for early stage epithelial ovarian cancer  

PubMed Central

Background Epithelial ovarian cancer is diagnosed in 4500 women in the UK each year of whom 1700 will ultimately die of their disease.Of all cases 10% to 15% are diagnosed early when there is still a good possibility of cure. The treatment of early stage disease involves surgery to remove disease often followed by chemotherapy. The largest clinical trials of this adjuvant therapy show an overall survival (OS) advantage with adjuvant platinum-based chemotherapy but the precise role of this treatment in subgroups of women with differing prognoses needs to be defined. Objectives To systematically review the evidence for adjuvant chemotherapy in early stage epithelial ovarian cancer to determine firstly whether there is a survival advantage of this treatment over the policy of observation following surgery with chemotherapy reserved for treatment of disease recurrence, and secondly to determine if clinical subgroups of differing prognosis based on histological sub-type, or completeness of surgical staging, have more or less to gain from chemotherapy following initial surgery. Search methods We performed an electronic search using the Cochrane Gynaecological Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL 2011, Issue 3), MEDLINE (1948 to Aug week 5, 2011) and EMBASE (1980 to week 36, 2011). We developed the search strategy using free-text and medical subject headings (MESH). Selection criteria We selected randomised clinical trials that met the inclusion criteria set out based on the populations, interventions, comparisons and outcome measures. Data collection and analysis Two review authors independently extracted data and assessed trial quality. Disagreements were resolved by discussion with a third review author. We performed random-effects meta-analyses and subgroup analyses. Main results Five randomised controlled trials (RCTs), enrolling 1277 women, with a median follow-up of 46 to 121 months, met the inclusion criteria. Four trials were included in the meta-analyses and we considered them to be at a low risk of bias. Meta-analysis of five-year data from three trials indicated that women who received adjuvant platinum-based chemotherapy had better overall survival (OS) than those who did not (1008 women; hazard ratio (HR) 0.71; 95% confidence interval (CI) 0.53 to 0.93). Likewise, meta-analysis of five-year data from four trials indicated that women who received adjuvant chemotherapy had better progression-free survival (PFS) than those who did not (1170 women; HR 0.67; 95% CI 0.53 to 0.84). The trials included in these meta-analyses gave consistent estimates of the effects of chemotherapy. In addition, these findings were robust over time (10-year PFS: two trials, 925 women; HR 0.67; 95% CI 0.54 to 0.84). Subgroup analysis suggested that women who had optimal surgical staging of their disease were unlikely to benefit from adjuvant chemotherapy (HR for OS 1.22; 95% CI 0.63 to 2.37; two trials, 234 women) whereas those who had sub-optimal staging did (HR for OS 0.63; 95% CI 0.46 to 0.85; two trials, 772 women). One trial showed a benefit from adjuvant chemotherapy among women at high risk (HR for OS 0.48; 95% CI 0.32 to 0.72) but not among those at low/medium risk (HR for OS 0.95; 95% CI 0.54 to 1.66). However, these subgroup findings could be due to chance and should be interpreted with caution. Authors’ conclusions Adjuvant platinum-based chemotherapy is effective in prolonging the survival of the majority of patients who are assessed as having early (FIGO stage I/IIa) epithelial ovarian cancer. However, it may be withheld from women in whom there is well-differentiated encapsulated unilateral disease (stage 1a grade 1) or those with comprehensively staged Ib, well or moderately differentiated (grade 1/2) disease. Others with unstaged early disease or those with poorly differentiated tumours should be offered chemotherapy. A pragmatic approach may be necessary in clinical settings where optimal staging is not normally performed/achieved. In such settings, adjuvant chemotherap

Cardiopulmonary exercise testing as a predictor of complications in oesophagogastric cancer surgery  

PubMed Central

Introduction An anaerobic threshold (AT) of <11ml/min/kg can identify patients at high risk of cardiopulmonary complications after major surgery. The aim of this study was to assess the value of cardiopulmonary exercise testing (CPET) in predicting cardiopulmonary complications in high risk patients undergoing oesophagogastric cancer resection. Methods Between March 2008 and October 2010, 108 patients (83 men, 25 women) with a median age of 66 years (range: 38–84 years) underwent CPET before potentially curative resections for oesophagogastric cancers. Measured CPET variables included AT and maximum oxygen uptake at peak exercise (VO2 peak). Outcome measures were length of high dependency unit stay, length of hospital stay, unplanned intensive care unit (ICU) admission, and postoperative morbidity and mortality. Results The mean AT and VO2 peak were 10.8ml/min/kg (standard deviation [SD]: 2.8ml/min/kg, range: 4.6–19.3ml/min/kg) and 15.2ml/min/kg (SD: 5.3ml/min/kg, range: 5.4–33.3ml/min/kg) respectively; 57 patients (55%) had an AT of <11ml/min/ kg and 26 (12%) had an AT of <9ml/min/kg. Postoperative complications occurred in 57 patients (29 cardiopulmonary [28%] and 28 non-cardiopulmonary [27%]). Four patients (4%) died in hospital and 21 (20%) required an unplanned ICU admission. Cardiopulmonary complications occurred in 42% of patients with an AT of <9ml/min/kg compared with 29% of patients with an AT of ?9ml/min/kg but <11ml/min/kg and 20% of patients with an AT of ?11ml/min/kg (p=0.04). There was a trend that those with an AT of <11ml/min/kg and a low VO2 peak had a higher rate of unplanned ICU admission. Conclusions This study has shown a correlation between AT and the development of cardiopulmonary complications although the discriminatory ability was low. PMID:23484995

Neoadjuvant chemotherapy of gastric cancer with oral UFT (a mixture of uracil and fturafur) during the waiting period for surgery.  

PubMed

Our previous experience has demonstrated that growth of gastric cancer during the waiting period for surgery cannot be neglected, and some patients hope to receive prophylactic treatment to inhibit the growth of tumor until surgery. The present study was designed to assess the clinical benefits of preoperative chemotherapy with oral UFT for gastric cancer during the waiting period for surgery. Fifty patients with gastric cancer (24 early, 25 advanced and 1 recurrent cancers) were treated with oral UFT at 300-600 mg/day for 7-36 days before surgery and the objective responses and the postsurgical survivals were evaluated. In 42 of 50 patients objective responses of primary lesions were assessed by endoscopy or upper gastrointestinal series examination, and 2 CRs, 15 PRs and 25 NCs were seen (40% response). The histological effect was evaluated in 50 patients and the following classifications were made: grade 3 (complete disappearance or necrosis of tumor cells), 2; grade 2 (necrotic changes > 2/3 area), 4; grade 1b (> 1/3 area), 7; grade 1a (< 1/3 area), 15; and grade 0 (no histological changes), 22. A longer period of UFT administration was associated with CR or PR. All the patients underwent gastrectomy (38 curative and 12 palliative gastrectomies): all patients with Stage I-III primary gastric cancer are alive after surgery, and the 50% survival period of the patients with Stage IV cancer was 20 months. The side effects were not serious, including slight myelotoxicity, liver dysfunction and anorexia. It is concluded that preoperative chemotherapy for gastric cancer with oral UFT on outpatient basis may result in down-staging as well as the prevention of tumor growth during the waiting period for surgery without serious side effects.

Laparoscopy to predict the result of primary cytoreductive surgery in advanced ovarian cancer patients (LapOvCa-trial): a multicentre randomized controlled study  

PubMed Central

Background Standard treatment of advanced ovarian cancer is surgery and chemotherapy. The goal of surgery is to remove all macroscopic tumour, as the amount of residual tumour is the most important prognostic factor for survival. When removal off all tumour is considered not feasible, neoadjuvant chemotherapy (NACT) in combination with interval debulking surgery (IDS) is performed. Current methods of staging are not always accurate in predicting surgical outcome, since approximately 40% of patients will have more than 1 cm residual tumour after primary debulking surgery (PDS). In this study we aim to assess whether adding laparoscopy to the diagnostic work-up of patients suspected of advanced ovarian carcinoma may prevent unsuccessful primary debulking surgery for ovarian cancer. Methods Multicentre randomized controlled trial, including all gynaecologic oncologic centres in the Netherlands and their affiliated hospitals. Patients are eligible when they are planned for PDS after conventional staging. Participants are randomized between direct PDS or additional diagnostic laparoscopy. Depending on the result of laparoscopy patients are treated by PDS within three weeks, followed by six courses of platinum based chemotherapy or with NACT and IDS 3-4 weeks after three courses of chemotherapy, followed by another three courses of chemotherapy. Primary outcome measure is the proportion of PDS's leaving more than one centimetre tumour residual in each arm. In total 200 patients will be randomized. Data will be analysed according to intention to treat. Discussion Patients who have disease considered to be resectable to less than one centimetre should undergo PDS to improve prognosis. However, there is a need for better diagnostic procedures because the current number of debulking surgeries leaving more than one centimetre residual tumour is still high. Laparoscopy before starting treatment for ovarian cancer can be an additional diagnostic tool to predict the outcome of PDS. Despite the absence of strong evidence and despite the possible complications, laparoscopy is already implemented in many countries. We propose a randomized multicentre trial to provide evidence on the effectiveness of laparoscopy before primary surgery for advanced stage ovarian cancer patients.

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

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.

Extent of surgery in cancer of the colon: Is more better?  

PubMed Central

Since the introduction of total mesorectal excision as the standard approach in mid and low rectal cancer, the incidence of local recurrence has sharply declined. Similar attention to surgical technique in colon cancer (CC) has resulted in the concept of complete mesocolic excision (CME), which consists of complete removal of the intact mesentery and high ligation of the vascular supply at its origin. Although renewed attention to meticulous surgical technique certainly has its merits, routine implementation of CME is currently unfounded. Firstly, in contrast to rectal cancer, local recurrence originating from an incompletely removed mesentery is rare in CC and usually a manifestation of systemic disease. Secondly, although CME may increase nodal counts and therefore staging accuracy, this is unlikely to affect survival since the observed relationship between nodal counts and outcome in CC is most probably not causal but confounded by a range of clinical variables. Thirdly, several lines of evidence suggest that metastasis to locoregional nodes occurs early and is a stochastic rather than a stepwise phenomenon in CC, in essence reflecting the tumor-host-metastasis relationship. Unsurprisingly, therefore, comparative studies in CC as well as in other digestive cancers have failed to demonstrate any survival benefit associated with extensive, additional or extra-mesenteric lymphadenectomy. Finally, routine implementation of CME may cause patient harm by longer operating times, major vascular damage and autonomic nerve injury. Therefore, data from randomized trials reporting relevant endpoints are required before CME can be recommended as a standard approach in CC surgery. PMID:25574086

Understanding clinical strategies that may impact tumour growth and metastatic spread at the time of cancer surgery.  

PubMed

The role of the perioperative period during cancer surgery and its impact on patients' long-term cancer outcomes are of increasing interest. Anticipation and prevention of perioperative immunosuppression and targeted therapeutic interventions that translate to reduced cancer recurrence are increasingly being explored. These interventions may focus on reducing the systemic inflammatory response, the regional lymphatic flow induced by surgical inflammation and exposure to perioperative immunosuppressive agents. The challenge has been to provide evidence-based links between these hypothesised cancer 'reducing' strategies, our knowledge of cancer biology and tangible long-term clinical outcomes of improved recurrence-free and overall survival. Anaesthesiologists caring for patients with cancer may preferentially employ regional anaesthesia techniques and anti-inflammatory agents to minimise perioperative immunosuppression and preserve perioperative homeostasis. However, prospective trials powered for long-term cancer outcomes are necessary to provide an evidence base before these strategies are to be recommended for routine clinical practice. PMID:24267549

Current status of the use of antiadhesive agents for gastric cancer surgery: a questionnaire survey in South Korea  

PubMed Central

Purpose The aim of this study was to investigate the current status of the use of antiadhesive agents (AAdAs) via a questionnaire and to discuss the availability of AAdAs. Methods The survey was sent to a list of members that was approved by the Korean Gastric Association. The survey included questions on AAdA use by surgeons, the type of AAdAs used, and the reasons for not using AAdAs. Surgeons were also asked to describe complications related to AAdAs, and the reliability of its use. Results The response rate was 21%. The rates of frequent use stratified by procedure were 26.9% (14/52) for open gastrectomy, 5.9% (3/51) for laparoscopic gastrectomy, and 31.5% (17/54) for surgery for postoperative bowel obstruction (P < 0.01). After including data from the occasional use group, the corresponding values were 51.9% (27/52), 19.6% (10/51), and 70.4% (38/54), respectively (P < 0.01). Sefrafilm and Guardix were most commonly used for open procedures. Guardix and Interceed were most commonly used for laparoscopic surgery. The primary reasons for nonuse of AAdAs were ineffectiveness and high cost. Ten percent (4/40) of surgeons observed complications associated with AAdAs. A minority (17.3%, 9/52) had positive attitudes toward AAdAs. The majority of respondents expressed neutral (73.1%, 38/52) or negative (9.6%, 5/52) attitudes toward AAdAs. Conclusion The low use rates of AAdAs in gastric cancer surgery may be attributable to perceptions that AAdAs are ineffective, unreliable, and costly. We anticipate the emergence of promising antiadhesive strategies that reach far beyond the limitations of current products. PMID:23487148

Safety of partial breast reconstruction in extended indications for conservative surgery in breast cancer.  

PubMed

Breast conservation surgery after large volume excisions for women with relatively larger or multicentric operable breast cancer (OBC) and in some locally advanced breast cancers (LABC) post neo-adjuvant chemotherapy (NACT), is known to be a feasible option using a latissimus dorsi flap. However, the oncological safety of such a procedure is not well reported in literature. Two hundred and twenty one women with breast cancer (148-OBC, 73-LABC) underwent BCT plus LD during March 1998 to August 2009. One hundred and forty six women (72-LABC, 66-OBC) received prior NACT for downstaging, followed by completion of adjuvant therapy in all, including postoperative radiotherapy and hormone therapy where indicated. Women aged 20-62 years, with tumors 1.5-15 cm (median 5.0 cm), underwent volume replacement surgery with LD flap. All positive cut margins (total-4.9%, gross positive-1.3%) were re-excised to ensure negative margins. The mean surgical time for excision of primary with axillary clearance followed by volume replacement by LD was 5 h and mean hospital stay 6 days. Donor site morbidity was seen in 11 patients and 3 had minor recipient site infection. At a median follow up of 36 months, ten of 221 patients (4.5%) had failed locally (7-OBC, 3-LABC). The determinants of local recurrence were presence of lymphatic vascular invasion (p?=?0.016) and axillary metastasis (p?=?0.003). BCT plus LD flap is an oncologically safe, technically quick procedure with minimal morbidity, and should be offered to all eligible women as an extended breast conservation procedure. PMID:22693374

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.

Head and neck cancer surgery in an elderly patient population: a retrospective review.  

PubMed

Should advanced age be a contraindication to the surgical management of head and neck cancer patients? A retrospective chart review was performed of patients aged ?80 years treated surgically for a head and neck malignancy during the period 1996-2011 in a tertiary care cancer centre. The average follow-up was 32 months. Fifty-three patients were identified (mean age 85 years). Cardiovascular disease was the most prevalent co-morbidity (43%). Forty-five patients (85%) had oral cavity/oropharynx squamous cell carcinoma. Surgeries performed included 40 neck dissections and 12 microvascular free flaps. The average length of hospital stay (LOS) was 6.4 days. An increased LOS was significant in patients requiring free flap reconstruction (P<0.01). There were no perioperative deaths or free flap failures. The most common postoperative complications were cardiovascular (n=8), infection (n=10), and delirium (n=6). Thirty-four patients were discharged directly home. Free flap reconstruction did not adversely affect discharge disposition (P>0.05). More than 75% of patients did not report any major limitations to their activities of daily living. Major head and neck surgical procedures can be tolerated by patients of advanced age using careful patient selection. Age alone should not be a primary factor in the management of head and neck cancer patients. PMID:25223605

[Nutritional screening before surgery for esophageal cancer - current status and evaluation results].  

PubMed

The incidence of postoperative complications and mortality are usually higher in patients with preoperative malnutrition. Malnutrition often preexists, particularly in patients undergoing surgery for esophageal cancer, which is substantially invasive. It is therefore important to understand the nutritional condition of patients and actively control perioperative nutrition.Our hospital has been providing nutritional status screening for patients before resection of esophageal cancer, and we report the current status and evaluation results in this article.This screening included 158 patients requiring radical resection of esophageal cancer.Age, comorbidity with diabetes, body mass index(BMI), serum albumin(Alb), Onodera's prognostic nutritional index(PNI), and Glasgow prognostic score(GPS)were used as nutritional indicators to stratify patients for analysis.Evaluation parameters included the incidence of postoperative complications(any complication, pulmonary complications, psychiatric disorder, and anastomotic leakage)and rates of long-term postoperative hospitalization.The analysis indicated that age, BMI, serum Alb, PNI, and GPS are useful for predicting the onset of postoperative complications and prolonged postoperative hospitalization.For such patients, more active nutritional control should be provided.

Protocol for the OUTREACH trial: a randomised trial comparing delivery of cancer systemic therapy in three different settings - patient's home, GP surgery and hospital day unit  

PubMed Central

Background The national Cancer Reform Strategy recommends delivering care closer to home whenever possible. Cancer drug treatment has traditionally been administered to patients in specialist hospital-based facilities. Technological developments mean that nowadays, most treatment can be delivered in the out-patient setting. Increasing demand, care quality improvements and patient choice have stimulated interest in delivering some treatment to patients in the community, however, formal evaluation of delivering cancer treatment in different community settings is lacking. This randomised trial compares delivery of cancer treatment in the hospital with delivery in two different community settings: the patient's home and general practice (GP) surgeries. Methods/design Patients due to receive a minimum 12 week course of standard intravenous cancer treatment at two hospitals in the Anglia Cancer Network are randomised on a 1:1:1 basis to receive treatment in the hospital day unit (control arm), or their own home, or their choice of one of three neighbouring GP surgeries. Overall patient care, treatment prescribing and clinical review is undertaken according to standard local practice. All treatment is dispensed by the local hospital pharmacy and treatment is delivered by the hospital chemotherapy nurses. At four time points during the 12 week study period, information is collected from patients, nursing staff, primary and secondary care teams to address the primary end point, patient-perceived benefits (using the emotional function domain of the EORTC QLQC30 patient questionnaire), as well as secondary end points: patient satisfaction, safety and health economics. Discussion The Outreach trial is the first randomised controlled trial conducted which compares delivery of out-patient based intravenous cancer treatment in two different community settings with standard hospital based treatment. Results of this study may better inform all key stakeholders regarding potential costs and benefits of transferring clinical services from hospital to the community.

Acute myelogenous leukemia suddenly developing just after surgery for advanced gastric cancer: report of a case.  

PubMed

We report a case of acute myelogenous leukemia (AML) developing just after surgery for advanced gastric cancer, before adjuvant chemotherapy was started. Immature white blood cells were recognized in the peripheral blood from postoperative day (POD) 1. The patient's clinical status and bone scintigraphy showed no evidence of bone metastasis. Acute myelogenous leukemia was diagnosed by an aspiration biopsy of the bone marrow. If the AML had developed later and had become remarkable during or after adjuvant chemotherapy, the differential diagnosis between de novo and therapy-related leukemia would have been very difficult. Most leukemias that develop during the course of chemotherapy or radiotherapy, or both, are indisputably considered to be therapy-related. Thus, we report the clinical course of this patient with reference to the related literature to warn surgeons of the possibility of this unusual manifestation. PMID:15674499

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.

Radiotherapy versus surgery in the treatment of cervix stage Ib cancer.  

PubMed

In the years 1971-77 we have treated 250 Stage Ib patients with cancers of the cervix. One hundred twenty-three (49.2%) underwent a radical surgery, 37 had a classical Wertheim-Meigs operation, and 86 had a lymphadenectomy that was extended to the lumbar-aortic region. When feasible, all patients received postoperative radium therapy on the vaginal vault. The remaining 127 patients received a complete course of radiotherapy. This was not a randomized clinical trial. In fact surgery was preferred for patients who were younger (mean age: 49.6 years) and more physically fit, while radiotherapy was the treatment chosen for those who were older (mean age: 57.7) and generally less fit or obese. The 5 year NED survival was 89.3% in the surgical group and 90.9% in the radiotherapy group (P less than .05). Four fatal complications were observed in the surgical group (3.2%). Rate and causes of failures or complications are analyzed in detail. PMID:6662745

A virtual reality endoscopic simulator augments general surgery resident cancer education as measured by performance improvement.  

PubMed

Colorectal cancer is the second most common cause of death in the USA. The need for screening colonoscopies, and thus adequately trained endoscopists, particularly in rural areas, is on the rise. Recent increases in required endoscopic cases for surgical resident graduation by the Surgery Residency Review Committee (RRC) further emphasize the need for more effective endoscopic training during residency to determine if a virtual reality colonoscopy simulator enhances surgical resident endoscopic education by detecting improvement in colonoscopy skills before and after 6 weeks of formal clinical endoscopic training. We conducted a retrospective review of prospectively collected surgery resident data on an endoscopy simulator. Residents performed four different clinical scenarios on the endoscopic simulator before and after a 6-week endoscopic training course. Data were collected over a 5-year period from 94 different residents performing a total of 795 colonoscopic simulation scenarios. Main outcome measures included time to cecal intubation, "red out" time, and severity of simulated patient discomfort (mild, moderate, severe, extreme) during colonoscopy scenarios. Average time to intubation of the cecum was 6.8 min for those residents who had not undergone endoscopic training versus 4.4 min for those who had undergone endoscopic training (p?cancer education and measuring improvement in resident performance after formal clinical endoscopic training.

Percutaneous comprehensive cryoablation for metastatic esophageal cancer after failure of radical surgery.  

PubMed

Esophageal cancer is common in China. There is a lack of treatment strategies for metastatic esophageal cancer (MEC) after radical surgery on the primary tumor. Cryoablation is an attractive option because tumor necrosis can be safely induced in a minimally invasive manner. This study assessed its therapeutic effect in MEC after failure of radical surgery. One hundred and forty patients met the inclusion criteria from May, 2003 to March, 2011. Comprehensive cryotherapy of multiple metastases was performed on 105 patients; 35 received chemotherapy. No severe complications occurred during or after cryoablation. Overall survival (OS) was assessed according to therapeutic protocol, pathologic type, treatment timing and number of procedures. The OS of patients who received comprehensive cryoablation (44±20 months) was significantly longer than that of those who underwent chemotherapy (23±24 months; P=0.0006). In the cryotherapy group, the OS for squamous cell carcinoma (45±19 months) was longer than that for adenocarcinoma (33±18 months; P=0.0435); the OS for timely cryoablation (46±19 months) was longer than that for delayed cryoablation (33±20 months; P=0.0193); the OS for multiple cryoablation (50±17 months) was longer than that for single cryoablation (37±20 months; P=0.0172); and the OS for cryo-immunotherapy (56±17 months) was longer than that for cryoablation alone (39±19 months; P=0.0011). Thus, comprehensive cryotherapy may have advantages over chemotherapy in the treatment of metastatic MEC and, in patients with squamous cell carcinoma, supplementary immunotherapy and timely and multiple cryoablation may be associated with a better prognosis.

Nanostring-Based Multigene Assay to Predict Recurrence for Gastric Cancer Patients after Surgery  

PubMed Central

Despite the benefits from adjuvant chemotherapy or chemoradiotherapy, approximately one-third of stage II gastric cancer (GC) patients developed recurrences. The aim of this study was to develop and validate a prognostic algorithm for gastric cancer (GCPS) that can robustly identify high-risk group for recurrence among stage II patients. A multi-step gene expression profiling study was conducted. First, a microarray gene expression profiling of archived paraffin-embedded tumor blocks was used to identify candidate prognostic genes (N?=?432). Second, a focused gene expression assay including prognostic genes was used to develop a robust clinical assay (GCPS) in stage II patients from the same cohort (N?=?186). Third, a predefined cut off for the GCPS was validated using an independent stage II cohort (N?=?216). The GCPS was validated in another set with stage II GC who underwent surgery without adjuvant treatment (N?=?300). GCPS was developed by summing the product of Cox regression coefficients and normalized expression levels of 8 genes (LAMP5, CDC25B, CDK1, CLIP4, LTB4R2, MATN3, NOX4, TFDP1). A prospectively defined cut-point for GCPS classified 22.7% of validation cohort treated with chemoradiotherapy (N?=?216) as high-risk group with 5-year recurrence rate of 58.6% compared to 85.4% in the low risk group (hazard ratio for recurrence?=?3.16, p?=?0.00004). GCPS also identified high-risk group among stage II patients treated with surgery only (hazard ratio?=?1.77, p?=?0.0053). PMID:24598828

Transoral Robotic Surgery for Oropharyngeal Cancer: Long Term Quality of Life and Functional Outcomes  

PubMed Central

Objective To determine swallowing, speech and quality of life (QOL) outcomes following transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC). Design Prospective cohort study. Setting Tertiary care academic comprehensive cancer center. Patients 81 patients with previously untreated OPSCC. Intervention Primary surgical resection via TORS and neck dissection as indicated. Main Outcome Measures Patients were asked to complete the Head and Neck Cancer Inventory (HNCI) pre-operatively and at 3 weeks as well as 3, 6 and 12 months post-operatively. Swallowing ability was assessed by independence from a gastrostomy tube (G-Tube). Clinicopathological and follow-up data were also collected. Results Mean follow-up time was 22.7 months. HNCI response rates at 3 weeks and 3, 6, and 12 months were 79%, 60%, 63%, 67% respectively. There were overall declines in speech, eating, aesthetic, social and overall QOL domains in the early post-operative periods. However, at 1 year post-TORS scores for aesthetic, social and overall QOL remained high. Radiation therapy was negatively correlated with multiple QOL domains (p<0.05), while age > 55 years correlated with lower speech and aesthetic scores (p<0.05). HPV status did not correlate with any QOL domain. G-Tube rates at 6 and 12 months were 24% and 9%, respectively. The extent of TORS (> 1 oropharyngeal site resected) and age > 55 years predicted the need for a G-Tube at any point after TORS (p<0.05). Conclusions Patients with OPSCC treated with TORS maintain a high QOL at 1 year after surgery. Adjuvant treatment and advanced age tend to decrease QOL. PMID:23576186

Efficacy of Surgery and Adjuvant Therapy in Older Patients With Colorectal Cancer: A STROBE-compliant article.  

PubMed

The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age ?70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear. From two prospective Swedish databases, we assessed a cohort of 1021 patients who underwent curative surgery for stage I, II, or III primary CRC, with or without adjuvant chemotherapy/radiotherapy. Of the patients with colon cancer (n?=?467), 182 (39%) were aged <70 years, 162 (35%) aged 70 to 80 years, and 123 (26%) were aged ?80 years. Of rectal cancer patients (n?=?554), 264 (48%) were aged <70 years, 234 (42%) aged 70 to 80 years, and 56 (10%) aged ?80 years. Older patients with either colon or rectal cancer had higher comorbidity than did younger patients. Older patients with colon cancer had equivalent postoperative morbidity and 30-day mortality to younger patients. Rectal cancer patients aged ?80 years had a higher 30-day mortality than younger patients (odds ratio [OR], 2.37; 95% confidence interval [CI], 1.6-4.55; P?=?0.03). For either colon or rectal cancer, adjuvant chemotherapy compromised the 5-year overall survival (OS) of older patients with stage II disease and had no effect on those with stage III disease. Receiving adjuvant chemotherapy was a poor factor of OS for older patients with either colon (HR 1.88, 95% CI: 1.20-4.35, P?=?0.03) or rectal cancer (HR 1.72, 95% CI: 1.05-2.26, P?=?0.004). Preoperative short-course radiotherapy improved both OS and local control for older patients with stage III rectal cancer and had no effect on those with stage II disease. Radiotherapy was a favorable factor for the OS of the older patients with rectal cancer (HR 0.42, 95% CI: 0.21-3.57, P?=?0.01). In conclusion, Older CRC patients had equal safety of surgery as younger patients, except rectal cancer patients aged ?80 years that had a higher mortality. Adjuvant 5FU-based chemotherapy did not benefit older CRC patient, while neoadjuvant radiotherapy improved the prognosis of older patients with stage III rectal cancer. PMID:25526455

Dosimetric Evaluation of Different Intensity-Modulated Radiotherapy Techniques for Breast Cancer After Conservative Surgery.  

PubMed

Intensity-modulated radiotherapy (IMRT) potentially leads to a more favorite dose distribution compared to 3-dimensional or conventional tangential radiotherapy (RT) for breast cancer after conservative surgery or mastectomy. The aim of this study was to compare dosimetric parameters of the planning target volume (PTV) and organs at risk (OARs) among helical tomotherapy (HT), inverse-planned IMRT (IP-IMRT), and forward-planned field in field (FP-FIF) IMRT techniques after breast-conserving surgery. Computed tomography scans from 20 patients (12 left sided and 8 right sided) previously treated with T1N0 carcinoma were selected for this dosimetric planning study. We designed HT, IP-IMRT, and FP-FIF plans for each patient. Plans were compared according to dose-volume histogram analysis in terms of PTV homogeneity and conformity indices (HI and CI) as well as OARs dose and volume parameters. Both HI and CI of the PTV showed statistically significant difference among IP-IMRT, FP-FIF, and HT with those of HT were best (P < .05). Compared to FP-FIF, IP-IMRT showed smaller exposed volumes of ipsilateral lung, heart, contralateral lung, and breast, while HT indicated smaller exposed volumes of ipsilateral lung but larger exposed volumes of contralateral lung and breast as well as heart. In addition, HT demonstrated an increase in exposed volume of ipsilateral lung (except for fraction of lung volume receiving >30 Gy and 20 Gy), heart, contralateral lung, and breast compared with IP-IMRT. For breast cancer radiotherapy (RT) after conservative surgery, HT provides better dose homogeneity and conformity of PTV compared to IP-IMRT and FP-FIF techniques, especially for patients with supraclavicular lymph nodes involved. Meanwhile, HT decreases the OAR volumes receiving higher doses with an increase in the volumes receiving low doses, which is known to lead to an increased rate of radiation-induced secondary malignancies. Hence, composite factors including dosimetric advantage, clinical effect, and economic burden should be taken into comprehensive consideration when choosing an RT technique in clinical practice.

Initial Clinical Experience with Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy in Signet-Ring Cell Gastric Cancer with Peritoneal Metastases  

PubMed Central

Purpose Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been shown to improve survival in select patients with gastric cancer and peritoneal metastases. It remains unclear, however, whether this multimodal treatment protocol is also beneficial for signet-ring cell gastric cancer (SRC) patients with peritoneal metastases. Materials and Methods Clinical data of patients scheduled for upfront systemic chemotherapy consisting of 5-FU (2,600 mg/m2), folinic acid (200 mg/m2), docetaxel (50 mg/m2), and oxaliplatin (85 mg/m2) followed by CRS and HIPEC using cisplatin (50 mg/m2) at the Comprehensive Cancer Center, University Hospital Tübingen, Germany were retrospectively analyzed. Results Eighteen consecutive patients for whom irresectability has been ruled out by a computed tomography scan were enrolled. However, complete cytoreduction could only be achieved in 72% of patients. When categorizing patients with respect to the completeness of cytoreduction, we found no difference between both groups considering tumor- or patient-related factors. The overall complication rate following complete cytoreduction and HIPEC was 46%. Within a median follow-up of 6.6 (0.5~31) months, the median survival for CRS and HIPEC patients was 8.9 months as opposed to 1.1 months for patients where complete cytoreduction could not be achieved. Following complete cytoreduction and HIPEC, progression-free survival was 6.2 months. Conclusions In SRC with peritoneal metastases, the prognosis appears to remain poor irrespective of complete CRS and HIPEC. Moreover, complete cytoreduction could not be achieved in a considerable percentage of patients. In SRC, CRS and HIPEC should be restricted to highly selective patients in order to avoid exploratory laparotomy. PMID:25061539

Determination of standard number, size and weight of mediastinal lymph nodes in postmortem examinations: reflection on lung cancer surgery  

PubMed Central

Background Mediastinal lymph node dissection is an essential component of lung cancer surgery. Literature lacks established information regarding the number and size of the healthy lymph nodes. In this postmortem autopsy study, we aim to define the number, size and weight of the lymph nodes in each mediastinal lymph node station. To implement the data for the clinical practice, we analyzed the possible number of nodes to be dissected in a systematic mediastinal lymph node dissection from the right and left sides during lung cancer surgery. Methods Sixty-two samples obtained from cadavers who did not die from chest malignancies, extrathoracic malignancies, any kind of infections or previous hospitalization before the death were included to the study. The locations of the nodes were recorded according to the American Thoracic Society Mediastinal Lymph Node Map. The number, size and weight of the nodes were determined at each station. Results Median age of the cadavers was 39 years. Primary causes of death were asphyxia in 10 (16.1%) subjects, trauma in 29 (46.8%) subjects, cardiovascular problems in 10 (16.1%) subjects, and undetermined in 13 (21%) subjects. The median number of lymph nodes resected from each patient was 23 (range: 11–54). The right sided paratracheal lymph nodes (Station 2R and 4R) were more frequent, heavier and longer than left sided lymph nodes (Station 2L and 4L) at the paratrecheal region. Right sided inferior mediastinal lymph nodes were heavier and longer than the left ones; however, their availability was more often on the left. Conclusions The properties of mediastinal lymph nodes at particular stations are different for number, size and weight. Station 4R and 7 have the highest number of nodes followed by stations 5 and 6. We recommend removing the lymph nodes of these stations completely in lung cancer patients to rule out the possibility of micrometastatic disease. Diameter of normal lymph node may be 1 cm for the stations other than 4R and 7, but the definition of normal diameter of a lymph node at the stations 4R and 7 may be changed as 1,5 cm and 2,0 cm, respectively. Weight of the nodes may be a new subject to study and may be defined as a new modality to define a staging to be more accurate and the issue needs further investigations. PMID:23591054

Patients with Single Brain Metastasis from Non-Small Cell Lung Cancer Equally Benefit from Stereotactic Radiosurgery and Surgery: A Systematic Review  

PubMed Central

Background The appropriate treatment of non-small cell lung cancer (NSCLC) with single brain metastasis (SBM) is still controversial. A systematic review was designed to evaluate the effectiveness of neurosurgery and stereotactic radiosurgery (SRS) in patients with SBM from NSCLC. Material/Methods PUBMED, EMBASE, the Cochrane Library, Web of Knowledge, Current Controlled Trials, Clinical Trials, and 2 conference websites were searched to select NSCLC patients with only SBM who received brain surgery or SRS. SPSS 18.0 software was used to analyze the mean median survival time (MST) and Stata 11.0 software was used to calculate the overall survival (OS). Results A total of 18 trials including 713 patients were systematically reviewed. The MST of the patients was 12.7 months in surgery group and 14.85 months in SRS group, respectively. The 1, 2, and 5 years OS of the patients were 59%, 33%, and 19% in surgery group, and 62%, 33%, and 14% in SRS group, respectively. Furthermore, in the surgery group, the 1 and 3 years OS were 68% and 15% in patients with controlled primary tumors, and 50% and 13% in the other patients with uncontrolled primary tumors, respectively. Interestingly, the 5-year OS was up to 21% in patients with controlled primary tumors. Conclusions There was no significant difference in MST or OS between patients treated with neurosurgery and SRS. Patients with resectable lung tumors and SBM may benefit from the resection of both primary lesions and metastasis. PMID:25579245

Factors Associated with the Incidence of Local Recurrences of Breast Cancer in Women Who Underwent Conservative Surgery  

PubMed Central

Conservative surgery is considered the procedure of choice for women who are affected by early stage tumours. The local recurrence of cancer as a consequence of breast tissue conservation is a growing concern. This study aimed to describe the sociodemographic and clinical profiles of women who had local recurrences of breast cancer after conservative surgery and to examine the associations between sociodemographic and clinical variables and the incidence of tumour recurrence in these women. The retrospective cohort included 880 women who were diagnosed with breast cancer and underwent conservative surgery between January 2000 and December 2010. Recurrences occurred in 60 patients, and the mean age of the women at diagnosis was 48.8 years. Predictive factors for local recurrence were young age (<39 years) (P = 0.028 and OR = 10.93), surgical margin involvement (P = 0.001 and OR = 3.66), and Her-2 overexpression (P = 0.045 and OR = 1.94). The establishment of sociodemographic and clinical characteristics might help to select optimum treatments, which is a crucial challenge for public health in Brazil, especially with regard to reductions of surgery and hospitalisation expenditures in the Unified Health System (Sistema Único de Saúde—SUS).

Fish oil-supplemented parenteral nutrition in patients following esophageal cancer surgery: effect on inflammation and immune function.  

PubMed

Our aim was to investigate whether adding ?-3 polyunsaturated fatty acids (PUFAs) to parenteral nutrition (PN) could reduce inflammation and improve immune function in patients following esophageal cancer surgery. In this pilot study, 60 patients with esophageal cancer were divided into 2 groups (30 patients in each group). All patients had total scores of more than or equal to 3 on the nutritional risk screening (NRS2002) test recommended by the European Society of Parenteral Enteral Nutrition, which showed that all patients had nutritional risk and should receive nutritional support. Both groups received isocaloric and isonitrogenous PN. One group received a ?-3 PUFAs supplement. Key indicators of inflammation [serum procalcitonin (PCT) level and the ratio of CD4(+) to CD8(+) (CD4(+)/CD8(+) ratio)] were determined intraoperatively and 24, 72, and 144 h postoperatively. PCT level was notably lower and CD4(+)/CD8(+) ratio was markedly higher in the ?-3 PUFAs group (P = 0.007 for PCT level and P = 0.012 for CD4(+)/CD8(+) ratio) on postoperative day 6 but not on postoperative days 1 and 3. ?-3 PUFAs supplemented PN can reduce inflammation and improve immune function in patients following esophageal cancer surgery. A larger trial is required to see whether ?-3 PUFAs supplementation of PN improves the clinical outcomes of patients following esophageal cancer surgery. PMID:23368915

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

Clinical utility of preoperative evaluation of bronchial arteries by three-dimensional computed tomographic angiography for esophageal cancer surgery.  

PubMed

An identification of bronchial arteries (BAs) is critical in esophageal cancer surgery to avoid tracheobronchial ischemia and unexpected massive bleeding during surgical procedure particularly in thoracoscopic video-assisted esophagectomy. We describe the efficacy of three-dimensional computed tomographic angiography (3D-CTA) of BAs for preoperative evaluation in esophageal cancer surgery. Sixty-four patients with esophageal cancer who preoperatively underwent multidetector computed tomography examination were included in this study. We evaluated the number, origin, and intraoperative preservation rate of BAs, and we compared the number of thoracic paratracheal lymph nodes harvested between two groups comprising patients who either underwent preoperative 3D-CTA of BAs (3D-CTA group) or did not (non-3D-CTA group). The right and left BAs were preoperatively identified in 62 patients (97%) and 55 patients (86%), respectively, using 3D-CTA. In 34 patients (53%), the right BA originated as a common trunk with the right intercostal artery. In 48 patients (75%), the left BA originated from the descending aorta as a single or double branch. Some anomalies such as the right BA originated from the left subclavian artery were observed. In all patients, either the right or the left BA was preserved. The number of harvested lymph nodes in left side of paratrachea was significantly increased in 3D-CTA group, than those in non-3D-CTA group. 3D-CTA clearly revealed BA anatomy, contributing to BA preservation and safe and precise lymphadenectomy in esophageal cancer surgery. 3D-CTA of BAs is useful for preoperative evaluation in esophageal cancer surgery.

Application of a Complication Screening Method to Congenital Heart Surgery Admissions A Preliminary Report  

PubMed Central

There have been comprehensive screening methods developed to identify unwanted inpatient events. A comprehensive assessment of complication diagnoses during congenital heart surgery admissions has not been performed. We examined the frequency of complications identified by a complication screening method and their relationship to patient characteristics among congenital heart surgery admissions. Data were obtained from the Healthcare Cost and Utilization Project Kids' Inpatient Database 2000. Among congenital heart surgery admissions, age ?20 years, we identified International Classification of Disease, 9th Revision, Clinical Modification (ICD-9-CM) codes indicating complication. Complication diagnoses were categorized as related to drug/biologic, procedures, devices, implants and grafts, and radiation. We used the Risk Adjustment for Congenital Heart Surgery risk categories (1–6) to examine the association between case complexity and complications. Multivariate analyses estimated the odds for a complication diagnosis by patient characteristics, including age, prematurity, chromosomal anomalies, noncardiac structural anomalies, and surgical risk category. Among 12,717 cases, 4014 (32%) had at least 1 complication diagnosis code. Procedure-related complication diagnoses represented 75% of complication diagnoses; device, implant, or graft represented 21%; drug/biologic represented 4% and radiation represented 0%. Multivariate analyses demonstrated that higher surgical case complexity and older age had a greater risk for a complication diagnosis: Risk Category 2, odds ratio (OR) 1.8; 3 OR 2.9; 4 OR 2.9; 5 OR 5.0; 6 OR 4.1, relative to category 1, all p‹0.01; age ?12 years, OR 1.3, p‹0.001; ‹1 year OR 1.1, p = 0.31. Premature cases had decreased odds OR 0.4, p‹0.001. This complication screening method indicates that unwanted patient events occur frequently during congenital heart surgery admissions. Children undergoing complex congenital heart surgery are at greatest risk for these unwanted events. Further study of these events is needed to determine their preventability and severity.

Next generation design, development, and evaluation of cryoprobes for minimally invasive surgery and solid cancer therapeutics: in silico and computational studies.  

PubMed

Cryosurgery is a widely regarded minimally invasive surgery for treatment of various types of cancers. It involves destruction of cancer cells within a limited spatial domain by exposing them to very low temperatures while minimizing injury to surrounding peripheral healthy tissues. Surprisingly, despite increasing demands for cryosurgery, there has been limited innovation in the design of cryoprobes, particularly in solid tumors (e.g., breast, prostate, and lung cancers). For advances in cancer therapeutics, integrative biology research can illuminate the mechanistic interface between a surgical cryoprobe and its tissue site of action. Here, we describe the design and development of three novel low pressure liquid nitrogen (LN2) cryoprobes with different physical dimensions and the parameters that determine their effectiveness experimentally, using water and bio-gel as the phase changing mediums. Smaller diameter low pressure probes produced lesser cryogenic injury. Vapor Separator is found to be an effective means (particularly for smaller diameter probes) to remove the vapor lock in the LN2 low pressure cryoprobes and also to reduce the precooling time. The low pressure LN2 cryoprobes produced lower probe temperatures and consequently larger and faster iceball growth for low cooling loads. Additionally, a numerical code was written in MATLAB based on the Enthalpy method to simulate the bio-heat transfer in a cryosurgical process. The numerical code is validated by analytical solution, laboratory experiments, and data from an in vivo cryosurgery. The developed numerical code is presented herein to illustrate that LN2 cryoprobes capable of producing lower probe temperatures produce more efficient cryosurgical operation by reducing the buffer zone and duration of surgery.This is the first report, to the best of our knowledge, on design of the next generation of LN2 surgical cryoprobes. These new surgical cryoprobes offer potentials for future preclinical and clinical testing in solid cancers. PMID:25683889

[Present status and tasks for genetic testing and risk-reducing surgery in patients with hereditary breast and ovarian cancer].  

PubMed

In Japan, awareness of hereditary breast and ovarian cancer (HBOC) has gradually increased among health care workers and the general population. We focus on two current topics: genetic testing and risk-reducing surgery for HBOC. Genetic testing for BRCA1 and BRCA2, the genes responsible for HBOC, is performed to diagnose HBOC. PCR-direct sequencing is a standard method used for BRCA1/2 mutation analysis. Recently, genetic rearrangement of BRCA1 was reported in a Japanese patient with HBOC. Therefore, MLPA tests are also being included in routine genetic testing for the disease. The result of "uncertain significance, " which indicates unclear pathogenic significance, is obtained in about 3% of all patients who undergo BRCA1/2 genetic tests. Furthermore, novel candidate genes for HBOC, such as RAD51C, PALB2, and BRIP1, were recently identified. Prophylactic surgical intervention for HBOC includes procedures such as risk-reducing bilateral salpingo-oophorectomy (RRSO) and risk-reducing mastectomy(RRM). In Japan, RRSO is performed in very few patients at present. Increasing evidence from overseas indicates that RRSO contributes to a decreased incidence of ovarian/breast cancers and lowers overall mortality. Therefore, a system for performing RRSO was established in our institute. RRSO was approved to be performed as a clinical examination by our Institutional Review Board. The clinical significance of ipsilateral complete mastectomy and RRM remains unclear. Based on the NCCN guidelines, conservative mastectomy with radiation therapy is relatively contraindicated in patients with HBOC. However, several studies have reported that conservative mastectomy with radiation the rapydoes not increase the incidence of recurrent or metachronous breast cancers in the ipsilateral breast of mutation-positive patients when compared to mutation-negative or control patients. However, more aggressive malignancies seem to be included in the mutation-positive group(especially BRCA1 -mutation-positive cases). RRM clearly reduced the incidence of breast cancers. RRM may also be allowed as a treatment option for HBOC in Japan. PMID:22504676

Robot-assisted surgery for kidney cancer increased access to a procedure that can reduce mortality and renal failure.  

PubMed

Surgeons increasingly use robot-assisted minimally invasive surgery for a variety of medical conditions. For hospitals, the acquisition and maintenance of a robot requires a significant investment, but financial returns are not linked to any improvement in long-term patient outcomes in the current reimbursement environment. Kidney cancer provides a useful case study for evaluating the long-term value that this innovation can provide. Kidney cancer is generally treated through partial or radical nephrectomy, with evidence favoring the former procedure for appropriate patients. We found that robot-assisted surgery increased access to partial nephrectomy and that partial nephrectomy reduced mortality and renal failure. The value of the benefits of robot-assisted minimally invasive surgery to patients, in terms of quality-adjusted life-years gained, outweighed the health care and surgical costs to patients and payers by a ratio of five to one. In addition, we found no evidence that the availability of robot-assisted minimally invasive surgery increased the likelihood that inappropriate patients received partial nephrectomy. PMID:25646101

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.

Outcome After Conservative Surgery and Breast Irradiation in 5,717 Patients With Breast Cancer: Implications for Supraclavicular Nodal Irradiation  

SciTech Connect

Purpose: To evaluate the outcome and predictive factors of patients who underwent breast-conserving surgery and adjuvant radiotherapy to the whole breast only, without supraclavicular nodal irradiation. Methods and Materials: A total of 5,717 patients with pT1-T4 breast cancer were treated at the University of Florence. The median age of the patient population was 55 years (range, 30-80 years). All patients were followed for a median of 6.8 years (range, 1-27 years). Adjuvant chemotherapy was recommended in 1,535 patients (26.9%). Tamoxifen was prescribed in 2,951 patients (51.6%). The patients were split into three groups according to number of positive axillary nodes (PAN): P1, negative axillary lymph nodes; P2, one to three PAN; P3, more than three PAN. Results: The P3 patients had a higher incidence of supraclavicular fossa recurrence (SFR) compared with P2 and P1 patients. However, the incidence of SFR in P3 patients was low (only 5.5%), whereas the incidence of distant metastases (DM) was 27.2%. Distant metastasis was the only independent prognostic factor for breast cancer survival. Additionally, in the subgroup of patients who developed local recurrence, DM was the most important death predictor. Conclusion: Our series suggests that isolated SFR in patients who did not receive supraclavicular radiotherapy is infrequent, as well as in those patients who have more than three PAN, and SFR seems not to influence the outcome, which depends on DM occurrence.

Factors affecting morbidity, mortality and survival in patients undergoing surgery for rectal cancer in a district general hospital.  

PubMed Central

INTRODUCTION: This is a review of elective rectal cancer surgery during 1993-1999 at a single district general hospital to investigate the variables that affected the care of these patients. PATIENTS AND METHODS: A retrospective study of patients presenting with rectal adenocarcinoma to a district general hospital where total mesorectal excision was practiced over a 7-year period was performed to identify factors associated with complications, death and disease recurrence. RESULTS: Sixty-one patients developed a total of 89 complications and 30-day mortality was 8.3%. Overall, 81% of all resections and 86% of potentially curative resections were free of tumour at the circumferential resection margin. A positive circumferential resection margin and 30-day mortality were both associated with increased postoperative blood transfusion volume. Twenty-nine recurrences were detected during the follow-up period (mean, 21.7 months) and circumferential margin involvement by tumour, Dukes' stage, pre-operative functional status (ASA grade) and length of hospital stay correlated with disease-free survival. CONCLUSIONS: Surgical outcomes in lower volume hospitals are comparable with those reported by larger centres. PMID:16176691

Complications and Functional Results of Surgery for Locally Advanced Prostate Cancer  

PubMed Central

The role of surgery in clinical stage T3 prostate cancer (cT3 PCa) is still subject to debate. We reviewed the records of 139 consecutive patients who underwent a radical prostatectomy (RP) for cT3 PCa with a mean follow-up of 8 years. All data related to surgical and perioperative complications were collected. Continence and erectile function were assessed at 12 months postoperatively and long-term oncologic outcomes were analyzed. Rectal injury and injury of the obturator nerve occurred both in 0.7% of cases. No serious in-hospital complications were noted and no reintervention was needed. Lymphatic leakage was noted in 2.2% of patients and 1.4% experienced prolonged drainage of urine. In 7.2%, wound-related problems occurred. Anastomotic stricture occurred in 2.9%. These complication rates were not different compared to surgical series of RP in localized PCa. At 12 months, complete continence was 87.8% and erectile function had fully recovered in 6% and 10% of patients who underwent a non-nerve sparing or unilateral nerve-sparing procedure, respectively. 10-year estimated biochemical PFS, clinical PFS, CSS and OS were 51.8%, 85.6%, 94.6% and 85.9%, respectively. In cT3 PCa, RP is technically feasible with morbidity comparable to RP in clinically localized PCa. Long-term oncologic control was excellent. PMID:22291698

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

Conserving surgery - balance between good cosmetic aspect and local disease control in incipient breast cancer.  

PubMed

New acquisitions in the study of breast cancer, based on several retrospective and prospective studies, have led over the past decades to the possibility of applying conserving methods of treatment for breast cancer (breast conserving therapy -BCT) in incipient stages. Starting with 1996, a single surgical team, among others at the Bucharest Oncology Institute,performed BCT in 497 patients out of the total 2,256 cases of breast cancer treated. Work protocol consisted of tumour excision with safety margins, intraoperative histology exam,samples from all the walls of the remaining cavity, with intraoperative histology exam, axillary lymphadenectomy, followed by mandatory irradiation of the entire breast, associated or not with systemic or hormonal adjuvant treatment. 38 patients developed local disease recurrences, 14 of which in the first 5 years. In this paper we present the results obtained through BCT, as a means of supporting this type of treatment adequate for patients with initial stage breast cancer, with cosmetic results visibly superior to those of mastectomy.

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. PMID:25396004

Laser surgery in dermatology with application of superthin optical fiber by contact and noncontact method  

NASA Astrophysics Data System (ADS)

At present nobody doubts the advantages of minor laser surgery over the conventional one.Bloodless manipulations, ablation, minor injury to the tissues while using laser equipment ensures its wide application in such fields as dermatology and cosmetology, especially since the semiconductor lasers because available at the technological market. No doubt CO2 and solid laser are still playing an important role, however, their imperfect fiber optic qualities limit their use in these field,s where advantages of diode lasers with flexible and fine quartz-polymeric optical fiber are obvious. The elaboration of new diode surgical lasers made it possible to invent new surgical equipment for solving many medical problems in the optimal way. Application of contact and noncontact laser methods in dermatology, gynecological plastic surgery and otolaryngology is discussed. A combined use of these methods demonstrates a positive effect on therapy results and healing time.

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

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.

Magnifying Endoscopy with Narrow Band Imaging to Determine the Extent of Resection in Transoral Robotic Surgery of Oropharyngeal Cancer  

PubMed Central

Transoral robotic surgery (TORS) is a less invasive treatment that is becoming popular all over the world. One of the most important factors for achieving success in TORS is the ability to determine the extent of resection during the procedure as the extent of resection in the laryngopharynx not only affects oncological outcomes but also directly affects swallowing and voice functions. Magnifying endoscopy with narrow band imaging (ME-NBI) is an innovative optical technology that provides high-resolution images and is useful in detecting early superficial pharyngeal cancers, which are difficult to detect by standard endoscopy. A 55-year-old male with superficial oropharyngeal cancer has been successfully treated by combining MB-NBI with TORS and MB-NBI was useful in determining the extent of resection. ME-NBI with TORS will make it possible to achieve a higher ratio of minimally invasive treatment in pharyngeal cancer. PMID:25574412

Neuroendocrine tumors of the lung: the role of surgery in small cell lung cancer.

The role of surgery in the management of patients with SCLC remains controversial. Although 2 randomized studies have failed to show any benefit on survival by adding surgery to chemotherapy, retrospective and prospective reports showed that surgery offers a reasonable overall survival in a subset of patients with stage I and II SCLC. Patients' selection is fundamental, and it should include extensive radiologic staging and mediastinal lymph-node biopsy. The use of a PET scan is likely to improve the accuracy of staging. Through primary surgery or after induction chemotherapy, a complete tumor resection associated with systematic lymphadenectomy should be achieved. PMID:25065933

Human papilloma virus and survival of oropharyngeal cancer patients treated with surgery and adjuvant radiotherapy.

Impact of p16 protein, a surrogate marker for human papilloma virus induced cancer, p53 and EGFR as well as clinical factors on survival in a patient cohort with oropharyngeal squamous cell carcinoma (OPSCC) treated by surgical resection and adjuvant radiotherapy (RT) ± concomitant chemotherapy (CT). This is a retrospective analysis of patient's charts and tumor tissue. 57 patients were consecutively included and their tumor tissue assembled on a tissue microarray following immunohistochemical analysis. Survival times were estimated by means of Kaplan-Meier analysis. The importance of clinical and immunohistochemical factors for outcome was estimated by cox proportional hazard models. With 88 % 5-year overall survival, 91 % 5-year disease-specific survival and 91 % 5-year disease-free survival, respectively, we found excellent survival rates in this surgically treated patient cohort of mainly advanced OPSCC (93 % AJCC stage III or IV). The only factors positively influencing survival were p16 overexpression as well as p53 negativity and even more pronounced the combination of those biomarkers. Survival analysis of patients classified into three risk categories according to an algorithm based on p16, smoking, T- and N-category revealed a low, intermediate and high-risk group with significant survival differences between the low and the high-risk group. Patients with OPSCC can be successfully treated by surgery and adjuvant RT ± CT with a clear survival benefit of p16 positive, p53 negative patients. We recommend considering a combination of immunohistochemical (p16, p53) and clinical factors (smoking, T- and N-category) for risk stratification. PMID:24880469

Radiation pneumonitis in breast cancer patients treated with conservative surgery and radiation therapy  

SciTech Connect

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).

The aim of this study was to compare short-term outcomes between the FO and a conventional resection. Methods Between June 2008 and March 2012, a total of 242 patients who underwent a diverting ileostomy reversal after rectal cancer surgery were selected. Among them, 29 patients underwent the FO. Using propensity scores to adjust for body mass index, previous abdominal surgery history, rectal cancer surgery type (open vs. minimally invasive), and reason for ileostomy (protective aim vs. leakage management), we created a well-balanced cohort by matching each patient who underwent the FO, as the study group, with two patients who underwent a stapled or a hand-sewn technique with bowel resection (RE), as the control group (FO : RE = 1 : 2). Morbidity and perioperative recovery were compared between the two groups. Results Twenty-four and forty-eight patients were allocated to the FO and the RE groups, respectively. The mean operation time was 91 ± 26 minutes in the FO group and 97 ± 34 minutes in the RE group (P = 0.494). The overall morbidity rates were not different between the two groups (12.5% in FO vs. 14.6% in RE, P = 1.000). The rate of postoperative ileus was similar between the two groups (8.3% in FO vs. 12.5% in RE, P = 0.710). Although time to resumption of soft diet was shorter in the FO group than in the RE group, the lengths of hospital stay were not different. Conclusion The FO and the conventional resection have similar short-term clinical outcomes for diverting ileostomy reversal. PMID:24999462

Cost and effectiveness of video-assisted thoracoscopic surgery for clinical stage I non-small cell lung cancer: a population-based analysis  

PubMed Central

Background Video-assisted thoracoscopic surgery (VATS) is a minimally invasive alternative to conventional surgery (CS). We aimed to estimate the short-term cost-effectiveness of VATS vs. CS for clinical stage I non-small cell lung cancer (NSCLC-c-stage-I) patients from the payer’s perspective (National Health Insurance). Methods We identified NSCLC-c-stage-I patients diagnosed and received surgery within 2007-2009 through a comprehensive population-based database containing cancer and death registries, and reimbursement data. The duration of interest was 1 year. We included potential confounding covariables through literature searching and our own experience, and used a propensity score to construct a 1:1 population for adjustment. Results Our study population constituted 966 patients. The mean hospital stay [days, standard deviation (SD)] were 14.4 [7] and 16.1 (7.7) for VATS and CS respectively (P=0.002). The mean cost (2013 USD) and survival (year) was $22,316 vs. $21,976 and 0.98 vs. 0.974 for VATS vs. CS. The probability for VATS to be cost-effective (i.e., positive net benefit) was 0.49 & 0.56 at willingness-to-pay (WTP) 50,000 & 100,000 USD/life-year, respectively. Conclusions We provide the first empirical evidence that when compared to CS, VATS was potentially cost-effective in the short term (1 year) within the common WTP levels in Taiwan. PMID:25589961

Excimer laser-induced ablation in corneal surgery by a two-dimensional scanning method  

NASA Astrophysics Data System (ADS)

We describe a new multi-purpose maskless method of corneal surgery based on the point-by- point scanning of a focused laser beam which allows the application of a low-energy excimer laser. The crucial scanning parameters (beam diameter, step width, overlap...) to achieve a smooth corneal surface have been investigated. A computer program for the simulation and optimization of the point-by-point scanning process has been developed and tested on contact lenses consisting of PMMA. In addition, a method of measuring the eye-movement by means of the computer-assisted interpretation of photographs was proved for its application in an eye- tracking-system.

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

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.

Effect of long interval between hyperthermochemoradiation therapy and surgery for rectal cancer on apoptosis, proliferation and tumor response.  

PubMed

Neoadjuvant chemoradiotherapy is commonly used to improve the local control and resectability of locally advanced rectal cancer, with surgery performed after an interval of a number of weeks. We have been conducting a clinical trial of preoperative chemoradiotherapy in combination with regional hyperthermia (hyperthermo-chemoradiation therapy; HCRT) for locally advanced rectal cancer. In the current study we assessed the effect of a longer (>10 weeks) interval after neoadjuvant HCRT on pathological response, oncological outcome and especially on apoptosis, proliferation and p53 expression in patients with rectal cancer. Forty-eight patients with proven rectal adenocarcinoma who underwent HCRT followed by surgery were identified for inclusion in this study. Patients were divided into two groups according to the interval between HCRT and surgery, ? 10 weeks (short-interval group) and >10 weeks (long-interval group). Patients in the long-interval group had a significantly higher rate of pathological complete response (pCR) (43.5% vs. 16.0%) than patients of the short-interval group. Patients of the long-interval group had a significantly higher rate of down-staging of T-stage (78.3% vs. 36.0%) and relatively higher rate of that of N-stage (52.2% vs. 36.0%) than patients of the short-interval group. Furthermore, apoptosis in the long-interval group was relatively higher compared to that of the short-interval group, without a significant difference in the Ki-67 proliferative index and expression of p53 in the primary tumor. In conclusion, we demonstrated that a longer interval after HCRT (>10 weeks) seemed to result in a better chance of a pCR, a result confirmed by the trends in tumor response markers, including apoptosis, proliferation and p53 expression.

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

Beneficial effect of autologous blood transfusion on infectious complications after colorectal cancer surgery.  

PubMed

Homologous blood transfusion has been associated with an increased risk of postoperative infectious complications. To test the clinical consequences of this apparently immunosuppressive effect of homologous blood in a controlled trial, we designed a study in which the control group deposited autologous blood before their operations for use should transfusion be needed. We enrolled 120 patients with apparently curable colorectal cancer who were able to predeposit autologous blood (haemoglobin > 12.5 g/dL). 62 patients were assigned to receive homologous blood if blood transfusions were needed during operation, and the other 58 to receive their own predeposited blood followed, if necessary, by homologous blood [corrected]. Despite the similarity between the groups in factors known to affect the risk of postoperative infections, there was a significant difference in postoperative infection rate between the homologous and autologous blood groups (17 [27%] vs 7 [12%], p < 0.05; unadjusted odds ratio 2.75 [95% CI 1.07-7.11). The rates of non-infectious complications were similar Probably because their preoperative blood depositing caused the autologous blood patients to have lower haemoglobin concentrations, they were more likely to require transfusion than were the homologous blood group (53 [91%] vs 37 [60%], p < 0.001; relative risk 1.53 [1.24-1.89]). 20 (35%) required homologous as well as autologous blood. To adjust for the many infection-related factors, we did multivariate regression analysis; tumour location, preoperative ASA index, and study group assignment were the only significant risk factors. The odds ratio for postoperative infections adjusted for these factors was 2.84 (1.02-7.98, homologous vs autologous). Testing of delayed-type hypersensitivity responses before and after surgery showed decreases in both mean diameter and number of positive reactions in recipients of homologous blood and slight increases in those who received autologous blood. This study shows the clinical potential of blood-transfusion-mediated immunomodulation, which may be important also in tumour immunology. PMID:7901637

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.

Updates on surgical management of advanced gastric cancer: new evidence and trends. Insights from the First International Course on Upper Gastrointestinal Surgery--Varese (Italy), December 2, 2011.  

PubMed

Between the Ninth International Gastric Cancer Congress (IGCC) in South-Korea (Seoul, 2011) and the Tenth IGCC in Italy (Verona, 2013), the Insubria University organized the First International Course on Upper Gastrointestinal Surgery (Varese, December 2, 2011), with the patronage of Italian Research Group for Gastric Cancer (IRGGC) and the International Gastric Cancer Association (IGCA). The Course was intended to be a comprehensive update and review on advanced gastric cancer (GC) staging and treatment from well-known international experts. Clinical, research, and educational aspects of the surgeon's role in the era of stage-adapted therapy were discussed. As highlighted in the meeting, in this final document we summarize and thoroughly analyze (with references only for well-acquired randomized control trials) the new and old open problems in surgical management of advanced GC. Between the Ninth (Seoul, 2011) and the Tenth (Verona,2013) International Gastric Cancer Congress, the First International Course on Upper Gastrointestinal Surgery (Varese, December 2, 2011) was organized by the University of Insubria. This congress received the patronage of the International Gastric Cancer Association and the Italian Research Group for Gastric Cancer. The aim was to discuss open issues in surgical management of advanced gastric malignancies. We considered the opinions of several recognized experts in the field from both the Eastern and Western world, focused on definition problems and oncological and technical issues to define the current principles of advanced gastric cancer (GC) surgery.

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.

Efficacy Evaluation of Subtotal and Total Gastrectomies in Robotic Surgery for Gastric Cancer Compared with that in Open and Laparoscopic Resections: A Meta-Analysis  

PubMed Central

Purposes Robotic gastrectomy (RG), as an innovation of minimally invasive surgical method, is developing rapidly for gastric cancer. But there is still no consensus on its comparative merit in either subtotal or total gastrectomy compared with laparoscopic and open resections. Methods Literature searches of PubMed, Embase and Cochrane Library were performed. We combined the data of four studies for RG versus open gastrectomy (OG), and 11 studies for robotic RG versus laparoscopic gastrectomy (LG). Moreover, subgroup analyses of subtotal and total gastrectomies were performed in both RG vs. OG and RG vs. LG. Results Totally 12 studies involving 8493 patients met the criteria. RG, similar with LG, significantly reduced the intraoperative blood loss than OG. But the duration of surgery is longer in RG than in both OG and LG. The number of lymph nodes retrieved in RG was close to that in OG and LG (WMD?=??0.78 and 95% CI, ?2.15?0.59; WMD?=?0.63 and 95% CI, ?2.24?3.51). And RG did not increase morbidity and mortality in comparison with OG and LG (OR?=?0.92 and 95% CI, 0.69?1.23; OR?=?0.72 and 95% CI, 0.25?2.06) and (OR?=?1.06 and 95% CI, 0.84?1.34; OR?=?1.55 and 95% CI, 0.49?4.94). Moreover, subgroup analysis of subtotal and total gastrectomies in both RG vs. OG and RG vs. LG revealed that the scope of surgical dissection was not a positive factor to influence the comparative results of RG vs. OG or LG in surgery time, blood loss, hospital stay, lymph node harvest, morbidity, and mortality. Conclusions This meta-analysis highlights that robotic gastrectomy may be a technically feasible alternative for gastric cancer because of its affirmative role in both subtotal and total gastrectomies compared with laparoscopic and open resections.

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.

Compositions and methods for cancer treatment using targeted carbon nanotubes  

SciTech Connect

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.

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

Radiochemotherapy With Cisplatin and 5-Fluorouracil After Transurethral Surgery in Patients With Bladder Cancer  

SciTech Connect

Purpose: To give an update on the long-term outcome of an intensified protocol of combined radiochemotherapy (RCT) with 5-fluorouracil (5-FU) and cisplatin after initial transurethral resection of bladder tumor (TURBT) with selective organ preservation in bladder cancer. Methods and Materials: One hundred twelve patients with muscle-invading or high-risk T1 (G3, associated Tis, multifocality, diameter >5 cm) bladder cancer were enrolled in a protocol of TURBT followed by concurrent cisplatin (20 mg/m{sup 2}/day as 30-min infusion) and 5-FU (600 mg/m{sup 2}/day as 120-h continuous infusion), administered on Days 1-5 and 29-33 of radiotherapy. Response to treatment was evaluated by restaging TURBT 4-6 weeks after RCT. In case of invasive residual tumor or recurrence, salvage cystectomy was recommended. Results: Ninety-nine patients (88.4%) had no detectable tumor at restaging TURBT; 71 patients (72%) have been continuously free from local recurrence or distant metastasis. Superficial relapse occurred in 13 patients and muscle-invasive recurrence in 11 patients. Overall and cause-specific survival rates for all patients were 74% and 82% at 5 years, respectively. Of all surviving patients, 82% maintained their own bladder, 79% of whom were delighted or pleased with their urinary condition. Hematologic Grade 3/4 toxicity occurred in 23%/6% and Grade 3 diarrhea in 21% of patients. One patient required salvage cystectomy due to a shrinking bladder. Conclusion: Concurrent RCT with 5-FU/cisplatin has been associated with acceptable acute and long-term toxicity. Overall and cause-specific survival rates are encouraging. More than 80% of patients preserved their well-functioning bladder.

Long-term results of tailored D(2) lymph node dissection after R(0) surgery for gastric cancer.  

PubMed

Implementation of extended lymph node dissection for gastric cancer in western non-specialized centers through tailoring its extent upon disease stage and patient comorbidities was suggested as a wise policy to reduce morbidity and mortality rates, albeit with a potential for undertreatment in elderly and/or comorbid patients. Current definition of R(0) resection for gastric cancer lacks consideration of treatment-related variables such as extended lymph node dissection. Few studies to date have tried to fill this gap in such a clinical context. A retrospective evaluation of factors influencing long-term results after R(0) surgery was done in a prospective series of a non-specialized western surgical unit during the implementation of D(2) lymphadenectomy. Univariate and multivariate analysis of 22 variables were performed on a prospective database of 233 consecutive R(0) resections performed by ten different surgeons in 10 years. Endpoint was disease-free survival calculated at 5 and at 10 years. Disease-free survival rates were independently influenced by age, American Society of Anesthesiologists (ASA) status and lymph node ratio. Subset analysis of the status at censor stratified for age and ASA status failed to identify any significant difference in disease recurrence rates. Lymph node ratio was the only treatment-related independent prognostic factor for long-term results after R(0) surgery for gastric cancer in the setting of a non-specialized western unit, where the extent of lymph node dissection needs to be tailored on the presence of comorbidities (ASA status).

Colonoscopy as a Method of Choice in the Diagnosis of Colorectal Cancer  

PubMed Central

Introduction: Epidemiological characteristics of colorectal cancer indicate that in the U.S. colorectal cancer is the second leading cause of death from malignancy, just behind lung cancer. In the 2000 there were approximately 130,200 new cases, of which 56,300 had lethal outcome. In the past 15 years, the incidence and mortality rate has been declining, especially in women. Colorectal cancer is mainly found in people older than 50 years. Carcinoembryonic antigen (CEA) is insufficiently specific for the early detection of the disease. Its normal value is less than 5 g/L in the serum. Elevated levels of CEA after surgery indicate a lack of radical surgery, residual neoplasm, hidden distant metastases or recurrent disease. Unfortunately, only 10-15% of patients with recurrent disease can be successfully re-operated (isolated metastases in the liver or lungs). Colorectal cancer is predominantly adenocarcinoma, the tumor has relatively slow growth. While symptoms occur relatively early, distant metastases have relatively late appearance. Goals: The goals of this study were to remind the fundamental facts about the nature of this disease, to stress the importance of early detection of BC-screening programs, to draw attention to contemporary attitudes in the field of diagnosis and treatment of colorectal cancer, and to show the experience in the treatment of this disease at the Surgical Departments of the General Hospital in Konjic. Results: In the period from 2008-2012 years, at the Surgical Department of the General Hospital in Konjic surgically treated are 34 patients who had colorectal malignancy. There were 21 (65 %) male and 13 females (35%). All patients belonged to the age group of 50-75 years. Only five patients or 15 % prior to admission to the hospital had been diagnosed with a malignant process. All others, or 85% of the total sample, were admitted to the hospital as emergency cases (erosive gastritis), and after, shorter preparation underwent surgery. Only five (15%) of patients were admitted electively, already diagnosed with colorectal tumors by colonoscopy. Total number of lethal outcomes at the department was 8 (24%). Three patients died due to cardio-respiratory failure and MOF, and 5 patients due to anastomotic failure and septic shock. Conclusion: In conclusion we can say that in our institution it is necessary to obtain the proper equipment (colonoscope) and educate personnel, so we can introduce colonoscopy as the mandatory screening method of examination, particularly for vulnerable groups.

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

Preoperative Chemoradiotherapy (CRT) Followed by Laparoscopic Surgery for Rectal Cancer: Predictors of the Tumor Response and the Long-Term Oncologic Outcomes  

SciTech Connect

Purpose: We have evaluated the predictors of a tumor response to chemoradiotherapy (CRT) and the long-term oncologic outcomes of preoperative CRT and laparoscopic surgery for patients who suffer from rectal cancer. Methods and Materials: The study involved 274 patients with locally advanced rectal cancer and who had been treated with preoperative CRT and curative laparoscopic total mesorectal excision between January 2003 and January 2009. We assessed the long-term oncologic outcomes, in terms of recurrence and survival, of the treated patients. Results: Forty-two (15.3%) of the 274 patients had complete pathologic responses (pCR). The pre-CRT carcinoembryonic antigen level was the only significant predictor of a pCR on the multivariate analysis (p = 0.01). The overall survival at 5 years was 73.1%, with a mean survival period of 59.7 months (95% CI, 57.1-62.3). The disease-free survival at 5 years was 67.3% with a mean survival period of 54.7 months (95% CI, 51.7-57.8). The pCR group had a higher rate of overall survival at 5 years than did the non-pCR group, and the difference was significant (86.0% vs. 71.2%; hazard ratio = 0.87; 95% CI, 0.78-0.96; p = 0.03). The cumulative incidences of local and distant recurrences at 5 years were 5.8% and 28.3%, respectively. A total of 84.5% (234 of 274) of the patients had their anal sphincters preserved. Grade 3 or 4 acute and long-term toxic effects occurred in 22.2% and 8.4% of the patients, respectively. Conclusion: Preoperative CRT and laparoscopic surgery seems safe and feasible with favorable long-term outcomes and a high rate of sphincter preservation for the patients with low-lying tumors of the rectum.

[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.

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.

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.

NIM: A Node Influence Based Method for Cancer Classification  

PubMed Central

The classification of different cancer types owns great significance in the medical field. However, the great majority of existing cancer classification methods are clinical-based and have relatively weak diagnostic ability. With the rapid development of gene expression technology, it is able to classify different kinds of cancers using DNA microarray. Our main idea is to confront the problem of cancer classification using gene expression data from a graph-based view. Based on a new node influence model we proposed, this paper presents a novel high accuracy method for cancer classification, which is composed of four parts: the first is to calculate the similarity matrix of all samples, the second is to compute the node influence of training samples, the third is to obtain the similarity between every test sample and each class using weighted sum of node influence and similarity matrix, and the last is to classify each test sample based on its similarity between every class. The data sets used in our experiments are breast cancer, central nervous system, colon tumor, prostate cancer, acute lymphoblastic leukemia, and lung cancer. experimental results showed that our node influence based method (NIM) is more efficient and robust than the support vector machine, K-nearest neighbor, C4.5, naive Bayes, and CART.

Delayed versus immediate exercises following surgery for breast cancer: a systematic review  

Microsoft Academic Search

SummaryBackground  Seroma formation, wound healing and fluid drainage are a concern for both surgeons and patients. Excessive fluid production can result in seroma formation, and inadequate drainage of seromas is known to cause infection, pain, discomfort and longer periods of hospitalisation. Postoperative exercises given to maintain movement of the arm are believed to increase the amount of fluid production following surgery.

Overview of single-port laparoscopic surgery for colorectal cancers: Past, present, and the future  

PubMed Central

Single-port laparoscopic surgery (SPLS) is implemented through a tailored minimal single incision through which a number of laparoscopic instruments access. Introduction of operation-customized port system, utilization of a camera without a separate external light, and instruments with different lengths has brought the favorable environment for SPLS. However, performing SPLS still creates several hardships compared to multiport laparoscopic surgery; a single-port system inevitably leads to clashing of surgical instruments due to crowding. To overcome such difficulties, investigators has developed novel concepts and maneuvers, including the concept of inverse triangulation and the maneuvers of pivoting, spreading out dissection, hanging suture, and transluminal traction. The final destination of SPLS is expected to be a completely seamless operation, maximizing the minimal invasiveness. Specimen extraction through the umbilicus can undermine cosmesis by inducing a larger incision. Therefore, hybrid laparoscopic technique, which combined laparoscopic surgical technique with natural orifice specimen extraction (NOSE) - i.e., transvaginal or transanal route-, has been developed. SPLS and NOSE seemed to be the best combination in pursuit of minimal invasiveness. In the near future, robotic SPLS with natural orifice transluminal endoscopic surgery’s way of specimen extraction seems to be pursued. It is expected to provide a completely or nearly complete seamless operation regardless of location of the lesion in the abdomen. PMID:24574772

Between 1985 and 1987, 134 patients with rectal cancer underwent a curative resection (52 abdominoperineal resections, 82 sphincter-saving resections) with extended pelvic lymphadenectomy and selective pelvic autonomic nerve preservation (PANP). PANP was classified into

Breast Cancer Recognition Using a Novel Hybrid Intelligent Method  

PubMed Central

Breast cancer is the second largest cause of cancer deaths among women. At the same time, it is also among the most curable cancer types if it can be diagnosed early. This paper presents a novel hybrid intelligent method for recognition of breast cancer tumors. The proposed method includes three main modules: the feature extraction module, the classifier module, and the optimization module. In the feature extraction module, fuzzy features are proposed as the efficient characteristic of the patterns. In the classifier module, because of the promising generalization capability of support vector machines (SVM), a SVM-based classifier is proposed. In support vector machine training, the hyperparameters have very important roles for its recognition accuracy. Therefore, in the optimization module, the bees algorithm (BA) is proposed for selecting appropriate parameters of the classifier. The proposed system is tested on Wisconsin Breast Cancer database and simulation results show that the recommended system has a high accuracy. PMID:23626945

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.

Is radiofrequency ablation or stereotactic ablative radiotherapy the best treatment for radically treatable primary lung cancer unfit for surgery?  

PubMed Central

A best evidence topic was constructed according to a structured protocol. The question addressed was whether radiofrequency (RF) offers better results than stereotactic ablative therapy in patients suffering from primary non-small-cell lung cancer (NSCLC) unfit for surgery. Of the 90 papers found using a report search for RF, 5 represented the best evidence to answer this clinical question. Concerning stereotactic ablative therapy, of the 112 papers found, 10 represented the best evidence to answer this clinical question. A manual search of the reference lists permitted us to include seven more articles. The authors, journal, date, country of publication, study type, group studied, relevant outcomes and results of these papers are given. We conclude that, on the whole, the 23 retrieved studies clearly support the use of stereotactic ablative therapy rather than RF in patients suffering from primary NSCLC unfit for surgery. Indeed, stereotactic ablative therapy offered a 5-year local control rate varying between 83 and 89.5%, whereas the local control rate after RF ranges from 58 to 68%, with a short follow-up of ?18 months. Furthermore, both overall survival and cancer-specific survival were better with stereotactic ablative therapy, with a 3-year overall survival ranging from 38 to 84.7% and the 3-year cancer-specific survival from 64 to 88%, whereas the 3-year OS, only reported in two studies, ranged from 47 to 74% for RF. Moreover, the post-interventional morbidity was superior for RF ranging from 33 to 100% (mainly composed by pneumothorax), whereas radiation pneumonitis and rib fracture, ranging, respectively, from 3 to 38% and 1.6 to 4%, were the primary complications following stereotactic ablative therapy. Hence, the current evidence shows that stereotactic ablative therapy is a safe and effective procedure and should be proposed first to patients suffering from primary NSCLC unfit for surgery. However, the published evidence is quite limited, mainly based on small studies of <100 patients. Moreover, so far there is no blind, prospective control, randomized study comparing these two techniques. Consequently, despite the encouragement of these preliminary results, they must be interpreted with caution. PMID:23054908

Incisional Hernia Following Hand-Assisted Laparoscopic Surgery for Renal Cell Cancer  

PubMed Central

Objectives: For renal cell cancer, the hand-assisted laparoscopic approach provides several advantages while maintaining equal advantages with regards to patient recovery. We offer our experience with laparoscopic hand-assisted radical nephrectomy and the incidence of ventral wall hernia. Methods: Between February 1999 and July 2002, we performed 50 laparoscopic hand-assisted radical nephrectomies. A midline or a muscle splitting right lower quadrant incision was used depending on the side of the tumor. Hand-port incisions were all between 7 cm and 8 cm and closed with #1 polydioxanone sulfate suture in a running fashion. Three (6%) patients developed hand-port incisional hernias. All hernias occurred in midline hand-port sites. The average body weight of those who developed an incisional hernia was 137 kg. Although the cause of incisional hernia is multifactorial, we believe that obesity plays a significant role. The technical limitations involved in closing a short, deep ventral incision combined with the earlier return to activity of laparoscopy patients put this patient population at significant risk. Conclusion: We now perform an interrupted closure with nonabsorbable suture for the hand-assist incision and limited activity for 4 weeks to 6 weeks post procedure in high-risk patients. We have had no further wound hernias since adopting these changes. PMID:15984709

Priorities for development of research methods in occupational cancer.  

PubMed Central

Occupational cancer research methods was identified in 1996 as 1 of 21 priority research areas in the National Occupational Research Agenda (NORA). To implement NORA, teams of experts from various sectors were formed and given the charge to further define research needs and develop strategies to enhance or augment research in each priority area. This article is a product of that process. Focus on occupational cancer research methods is important both because occupational factors play a significant role in a number of cancers, resulting in significant morbidity and mortality, and also because occupational cohorts (because of higher exposure levels) often provide unique opportunities to evaluate health effects of environmental toxicants and understand the carcinogenic process in humans. Despite an explosion of new methods for cancer research in general, these have not been widely applied to occupational cancer research. In this article we identify needs and gaps in occupational cancer research methods in four broad areas: identification of occupational carcinogens, design of epidemiologic studies, risk assessment, and primary and secondary prevention. Progress in occupational cancer will require interdisciplinary research involving epidemiologists, industrial hygienists, toxicologists, and molecular biologists. PMID:12524210

Re-emphasizing the concept of adequacy of intraoperative assessment of the axillary sentinel lymph nodes for identifying nodal positivity during breast cancer surgery  

Microsoft Academic Search

BACKGROUND: Although sentinel lymph node (SLN) biopsy is a standard of care for the evaluation of the axillary lymph nodes during breast cancer surgery, a substantial degree of variation exists among individual surgeons as to what represents an adequate assessment. The aim of the current study was to assess when metastatic disease was first identified within consecutively harvested SLN candidates

Ulcer, gastric surgery and pancreatic cancer risk: an analysis from the International Pancreatic Cancer Case–Control Consortium (PanC4)  

PubMed Central

Background Peptic ulcer and its treatments have been associated to pancreatic cancer risk, although the evidence is inconsistent. Methods We pooled 10 case–control studies within the Pancreatic Cancer Case–control Consortium (PanC4), including 4717 pancreatic cancer cases and 9374 controls, and estimated summary odds ratios (OR) using multivariable logistic regression models. Results The OR for pancreatic cancer was 1.10 [95% confidence interval (CI) 0.98–1.23] for history of ulcer (OR = 1.08 for gastric and 0.97 for duodenal ulcer). The association was stronger for a diagnosis within 2 years before cancer diagnosis (OR = 2.43 for peptic, 1.75 for gastric, and 1.98 for duodenal ulcer). The OR was 1.53 (95% CI 1.15–2.03) for history of gastrectomy; however, the excess risk was limited to a gastrectomy within 2 years before cancer diagnosis (OR = 6.18, 95% CI 1.82–20.96), while no significant increased risk was observed for longer time since gastrectomy. No associations were observed for pharmacological treatments for ulcer, such as antacids, H2-receptor antagonists, or proton-pump inhibitors. Conclusions This uniquely large collaborative study does not support the hypothesis that peptic ulcer and its treatment materially affect pancreatic cancer risk. The increased risk for short-term history of ulcer and gastrectomy suggests that any such association is due to increased cancer surveillance. PMID:23970016

The survival outcome and patterns of failure in node positive endometrial cancer patients treated with surgery and adjuvant radiotherapy with curative intent  

PubMed Central

Objective The purpose of this study was to evaluate the patterns of failure, overall survival (OS), disease-free survival (DFS) and factors influencing outcome in endometrial cancer patients who presented with metastatic lymph nodes and were treated with curative intent. Methods One hundred and twenty-six patients treated between January 1996 to December 2008 with surgery and adjuvant radiotherapy were identified from our service's prospective database. Radiotherapy consisted of 45 Gy in 1.8 Gy fractions to the whole pelvis. The involved nodal sites were boosted to a total dose of 50.4 to 54 Gy. Results The 5-year OS rate was 61% and the 5-year DFS rate was 59%. Grade 3 endometrioid, serous, and clear cell histologies and involvement of upper para-aortic nodes had lower OS and DFS. The number of positive nodes did not influence survival. Among the histological groups, serous histology had the worst survival. Among the 54 patients relapsed, only three (6%) failed exclusively in the pelvis and the rest of the 94% failed in extrapelvic nodal or distant sites. Patients with grade 3 endometrioid, serous and clear cell histologies did not influence pelvic failure but had significant extrapelvic failures (p<0.001). Conclusion Majority of node positive endometrial cancer patients fail at extrapelvic sites. The most important factors influencing survival and extrapelvic failure are grade 3 endometrioid, clear cell and serous histologies and involvement of upper para-aortic nodes. PMID:25142629

An association between preoperative anemia and decreased survival in early-stage non-small-cell lung cancer patients treated with surgery alone  

SciTech Connect

Purpose: Surgical resection is the mainstay of therapy for patients presenting with Stage I and II non-small-cell lung cancer (NSCLC). Despite optimal staging and surgery, these patients are still at significant risk for failure. The purpose of this study is to report a retrospective analysis of the outcome of patients treated with surgery alone, as well as to analyze prognostic factors associated with survival. Materials and Methods: From May 2000 to November 2002, there was a total of 125 patients who were treated with surgery for NSCLC at University of Maryland Medical Center. Of these, 82 Stage I and II patients who received surgery alone as the definitive therapy were identified. The median age of the entire cohort was 68 years (range, 43-88 years). There were 48 males and 34 females. Sixty-three patients (76.8%) underwent lobectomies whereas 19 patients (23.2%) underwent nonlobectomy (wedge resection or segmentectomy) procedures. Patients who received neoadjuvant or adjuvant radiation therapy or chemotherapy were excluded from the study. Factors included in univariate and multivariate analyses were age, sex, tumor histology, pathologic stage, p53 status, preoperative hemoglobin (Hgb), and type of surgery performed. Endpoints of the study were relapse-free survival (RFS) and overall survival (OS). Results: Median follow-up was 20.8 months (range, 0.4-43.2 months). For the entire cohort, the 2-year RFS was 66.0% and 2-year OS was 76.3%. Median survival for the entire cohort has not been achieved. In univariate analysis, the only factor that achieved statistical significance was preoperative Hgb level. Patients who had preoperative Hgb <12 mg/dL experienced significantly worse RFS (mean RFS: 26.6 months vs. 34.9 months, p = 0.043) and OS (median OS: 27 months vs. 42.5 months, p = 0.011). For Stage I patients (n = 72), the 2-year RFS and OS were 66.4% and 77.1%, respectively. In the subgroup of stage IA patients (n = 37), there was a trend toward decreased overall survival in the anemic patients (2-year OS of 65.6% vs. 90.9%, p = 0.07). For Stage II patients (n = 10), the 2-year RFS and OS were 60.0% and 66.7%. In the Cox multivariate regression analysis, the only factor that achieved statistical significance was preoperative Hgb, with patients with Hgb <12 mg/dL having decreased RFS (RR 4.1, p = 0.020) and OS (RR 2.9, p = 0.026). There was a trend toward worse RFS (p = 0.056) and OS (p = 0.068) in p53-negative patients (n = 39). Stage, histologic type, type of surgery performed, age, and sex did not affect outcome. Conclusions: In our cohort of mostly Stage I NSCLC patients treated with surgery only, preoperative Hgb <12 mg/dL predicted for worse outcome. This effect was observed even in the traditionally low-risk subgroup of completely resected stage IA patients. Much has been written in the literature about anemia causing possible worsening of tumor hypoxia within solid tumors, thereby increasing radio-resistance. This has been a popular argument to explain poorer outcomes of anemic patients with solid tumors who undergo radiotherapy. However, our data suggest that anemia may be a sign of a more aggressive tumor that is at an increased risk of failure independent of the treatment modality.

New "Fluid Biopsy" Detects Cancer Without Surgery | Physical Sciences in Oncology  

Cancer.gov

The first step in treating cancer is characterizing an individual’s tumor, and for most cancers that means going under the surgeon’s knife and having the tumor or a piece of it removed and sent for examination by a pathologist. Because surgical biopsies are highly invasive, they are only very rarely repeated and so they only provide a single snapshot of a patient’s cancer at the moment that the tumor or piece of tissue is removed from the patient’s body for initial characterization.

Safe Introduction and Quality Control of New Methods in Coronary Surgery  

PubMed Central

Introduction: The first part of the paper analyses off pump coronary bypass surgery (OPCAB), which is compared with traditional on-pump procedures (ONCAB). Furthermore ,the paper evaluates the use of a new automatic device for performance of the proximal anastomosis and finally the effect of intracoronary shunt on myocardial ischemia during OPCAB. The main goal of the paper is to demonstrate the importance of careful clinical studies during introduction of the new techniques in cardiac surgery. Methods: Statistical analysis was performed on a large clinical database from Buffalo, NY, USA comparing OPCAB and ONCAB. Subsequently, a sequential controlled clinical study compared patients operated with a new automatic connector device to patients operated with classic suture technique. Finally a randomized study was performed to evaluate the effect of the use of an intracoronary shunt during construction of distal anastomosis. Results: The studies from Buffalo demonstrated reduced complications rates in high risk patients when OPCAB techniques were used. The use of connector devices in saphenous venous anastomosis was clearly inferior to standard technique. Intracoronary shunt was found to be beneficial by preventing ischemia. Discussion: Numerous studies have studied the results of OPCAB vs ONCAB and although results are variable it seems that OPCAB is advantageous in high risk patients, while in low risk patients there are much less if any benefit. The results of the studies of connector devices caused the product to be taken off the market. The value of shunt in OPCAB was clearly demonstrated by the randomized studies. Conclusion: The investigations presented in this paper clearly demonstrates the importance of well-designed studies when new surgical methods are introduced. In the present period of rapid technological development, carefully controlled, un-biased clinical trials are crucial to preserve patient safety and avoid unjustified societal cost. PMID:23408734

Breast Cancer Surgery: Comparing Surgical Groups and Determining Individual Differences in Postoperative Sexuality and Body Change Stress  

PubMed Central

Women diagnosed and surgically treated for regional breast cancer (N = 190) were studied to determine the sexual and body change sequelae for women receiving modified radical mastectomy (MRM) with breast reconstruction in comparison with the sequelae for women receiving breast-conserving therapy (BCT) or MRM without breast reconstruction. The sexuality pattern for women receiving reconstructive surgery was one that was significantly different—with lower rates of activity and fewer signs of sexual responsiveness—than that for women in either of the other groups. Significantly higher levels of traumatic stress and situational distress regarding the breast changes were reported by the women receiving an MRM in contrast to the women treated with BCT. Using a model to predict sexual morbidity, regression analyses revealed that individual differences in sexual self-schema were related to both sexual and body change stress outcomes. PMID:10965644

Preoperative Body Mass Index, 30-Day Postoperative Morbidity, Length of Stay and Quality of Life in Patients Undergoing Pelvic Exenteration Surgery for Recurrent and Locally-Advanced Rectal Cancer  

PubMed Central

Purpose Malnutrition is associated with an increased risk of developing complications following gastrointestinal surgery, especially following radical surgeries such as pelvic exenteration. This study aims to determine if preoperative body mass index (BMI) is associated with 30-day morbidity, length of hospital stay and/or quality of life (QoL) in patients undergoing pelvic exenteration surgery for recurrent and locally-advanced rectal cancer prior to a prospective trial. Methods A review of all patients who underwent pelvic exenteration surgery prior to 2008 was performed. Patients were included if they had a documented BMI as well as a QoL measurement (Functional Assessment Cancer Therapy - Colorectal questionnaire). Results Thirty-one patients, with a mean age of 56 years, had preoperative height and weight data, as well as measures of postoperative QoL, and formed the study group. The numbers of patients with recurrent (n = 17) or locally-advanced rectal cancer (n = 14) were similar. The mean length of stay was 21 days while the mean BMI of the patients was 24.3 (± 5.9) kg/m2. The majority of the patients were either of normal weight (n = 15) or overweight/obese (n = 11). The average length of hospital stay was significantly longer in patients who were underweight compared to those who were of normal weight (F = 6.508, P = 0.006) and those who were overweight and obese (F = 6.508, P = 0.007). Conclusion This study suggests that a lower body mass index preoperatively is associated with a longer length of hospital stay. BMI is not associated with long-term QoL in this patient group. However, further prospective research is required. PMID:24851218

Defining the surgical planes on MRI improves surgery for cancer of the low rectum.  

PubMed

Cancer of the low rectum provides a challenge for both preoperative staging and optimum operative management. Current outcomes for patients with low rectal cancer are poor, particularly for those treated by abdominoperineal excision. It has been suggested that this poor outcome is due to an inherent oncological inferiority of the traditional abdominoperineal excision procedure, which might be explained by the unique anatomical features of the low rectum and the lack of clearly defined anatomical excision planes. In this Personal View, we discuss the anatomical and surgical planes available for the management of low rectal cancer, and describe the two-plane approach to low rectal cancer using the mesorectal plane and the extralevator plane.

Effect of melatonin on depressive symptoms and anxiety in patients undergoing breast cancer surgery: a randomized, double-blind, placebo-controlled trial.  

PubMed

Depression, anxiety and sleep disturbances are known problems in patients with breast cancer. The effect of melatonin as an antidepressant in humans with cancer has not been investigated. We investigated whether melatonin could lower the risk of depressive symptoms in women with breast cancer in a three-month period after surgery and assessed the effect of melatonin on subjective parameters: anxiety, sleep, general well-being, fatigue, pain and sleepiness. Randomized, double-blind, placebo-controlled trial undertaken from July 2011 to December 2012 at a department of breast surgery in Copenhagen, Denmark. Women, 30-75 years, undergoing surgery for breast cancer and without signs of depression on Major Depression Inventory (MDI) were included 1 week before surgery and received 6 mg oral melatonin or placebo for 3 months. The primary outcome was the incidence of depressive symptoms measured by MDI. The secondary outcomes were area under the curve (AUC) for the subjective parameters. 54 patients were randomized to melatonin (n = 28) or placebo (n = 26) and 11 withdrew from the study (10 placebo group and 1 melatonin group, P = 0.002). The risk of developing depressive symptoms was significantly lower with melatonin than with placebo (3 [11 %] of 27 vs. 9 [45 %] of 20; relative risk 0.25 [95 % CI 0.077-0.80]), giving a NNT of 3.0 [95 % CI 1.7-11.0]. No significant differences were found between AUC for the subjective parameters. No differences in side effects were found (P = 0.78). Melatonin significantly reduced the risk of depressive symptoms in women with breast cancer during a three-month period after surgery. PMID:24756186
