    Laparoscopy is widely recognized as feasible and safe approach to many oncologic and benign digestive conditions and is associated with an improved early outcome. Robotic surgery promises to overcome intrinsic limitations of laparoscopic surgery by a three-dimensional view and wristed instruments widening indications for a minimally invasive approach. To date, the more interesting applications of robotic surgery are those operations restricted to one abdominal quadrant and requiring a fine dissection and digestive reconstruction. While robot-assisted rectal and gastric surgery are becoming well-accepted options among the surgical community, applications of robotics in hepato-biliary and pancreatic surgery are still debated.

    The history of the integration of surgery is both extensive and complex involving internecine machinations that have, over time, variously encompassed the alchemical, religious, technological and biological phases of societal development. Thus, the discipline has evolved from a mystic rite through a guild phase to its current eristic status as a therapeutic modality considered by some as an art form as opposed to a quasi-scientific endeavour of often unpredictable beneficial effect. This brief prolepsis provides an exposition of the evolution of surgeons and surgical thought proceeding from Galen in 3rd century Rome through Paré of Renaissance France, Billroth of fin de siècle Vienna, to Kocher and Whipple of Bern and New York respectively. It is apparent that in surgery, ontogeny may not readily recapitulate phylogeny and thus the need for a contemporary revaluation of integration within a novel educational nexus that encompasses the burgeoning matrix of biotechnological, ethical and fiduciary revolution is a critical requirement. Such an exercise must embody contemporary scientific and educational advance with evolving societal goals that include ethical variances, fiduciary issues and alterations in individual perceptions of life quality at both the medical and personal level. An incorporation of the basic tenets of digestive surgery as well as a delineation of its potential direction is both a vital and necessary exercise to ensure the attainment of appropriate future goals of medical, ethical, societal, scientific and educational validity. Current medical and surgical training programmes and the sub-specialization system are archaic, cumbersome, cost ineffective and, for the most part, represent endless computations and permutations of intellectually antiquated and stultifying processes designed more than a hundred years ago. As such, the maieutic skills as well as the clinical vista available for the delivery of visceral disease care bear little relation to

    Stem cells of the digestive system are ideal in many ways for research, given they are abundant, highly proliferative and have a uniform structural arrangement. This in turn has enormously aided the research of cancer stem cells of the digestive system, which is now shaping our understanding of cancer stem cells. In this review, the recent advances in the understanding of cancer stem cells of the digestive system have been summarized, including aspects such as their identification, origin, cell-cycle dormancy, relationship with epithelial-mesenchymal transition, cellular metabolism and the underlying molecular mechanisms. Newly acquired knowledge concerning cancer stem cells have led to the development of novel cancer therapeutics with provisional yet encouraging results. © The Author 2014.

    Full Text Available Aim: The objective of the present study was to examine changes in the activity, surgical techniques and results from the process of centralization of complex digestive oncologic surgery in 2005-2012 as compared to 1996-2000. Material and methods: A retrospective cohort study employing the minimum basic data set of hospital discharge (MBDSHD 1996-2012 from public centers in Catalonia (Spain was performed. The population consisted of individuals aged > 18 who underwent digestive oncologic surgery (esophagus, pancreas, liver, stomach or rectum. Medical centers were divided into low, medium, and high-volume centers (≤ 5, 6-10, and > 10 interventions/year, respectively. The tendency Chi-squared test was used to assess the centralization of patients in high-volume centers and hospital mortality evolution during the study period. Logistic regression was performed to assess the relationship between volume and outcome. Results: A centralization of complex oncologic digestive surgery between 10% (liver and 46% (esophagus was obtained by means of a reduction in the number of hospitals that perform these interventions and a significant rise in the number of patients operated in high-volume centers (all types p ≤ 0.0001, except for esophagus. A significant decrease in mortality was observed, especially in esophagus (from 15% in 1996/2000 to 7% in 2009/12, p = 0.003 and pancreas (from 12% in 1996/2000 to 6% in 2009/12, p trend < 0.0001. Conclusions: A centralization of oncologic digestive surgery in high-volume centers and a reduction of hospital mortality in Catalonia were reported among esophageal and pancreatic cancers. However, no significant changes were found for others cancer types.

    Full Text Available Rectal cancer is a distinct subset of colorectal cancer where specialized disease-specific management of the primary tumor is required. There have been significant developments in rectal cancer surgery at all stages of disease in particular the introduction of local excision strategies for preinvasive and early cancers, standardized total mesorectal excision for resectable cancers incorporating preoperative short- or long-course chemoradiation to the multimodality sequencing of treatment. Laparoscopic surgery is also increasingly being adopted as the standard rectal cancer surgery approach following expertise of colorectal surgeons in minimally invasive surgery gained from laparoscopic colon resections. In locally advanced and metastatic disease, combining chemoradiation with radical surgery may achieve total eradication of disease and disease control in the pelvis. Evidence for resection of metastases to the liver and lung have been extensively reported in the literature. The role of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal metastases is showing promise in achieving locoregional control of peritoneal dissemination. This paper summarizes the recent developments in approaches to rectal cancer surgery at all these time points of the disease natural history.

    2008-01-01

    Tumours of the upper aero digestive tract represent the sixth most frequent kind of cancer in France and throughout the world. If the localised forms may be controlled in the long run in two thirds of cases by surgery or radiotherapy, only one third of locally advanced forms are accessible to a cure after association from radiotherapy and chemotherapy. Besides, with a median of survival less than six months, metastatic tumours present a catastrophic spontaneous prognosis among patients with a medical ground that is often heavily deteriorated by prolonged exposure to alcohol and tobacco. Thus, there is a necessity to implement adapted therapeutic strategies to each patient and based on satisfactory proof levels of effectiveness. Optimisation of existing chemotherapy protocols and development of new therapies, in particular of targeted therapies, remain an important objective in the hope to improve results of treatments in locally advanced and metastatic cancers of the oral cavity.

    In the current age of minimally invasive surgery, laparoscopic surgery for colon cancer has been established as oncologically equivalent to conventional open surgery. The advantages of laparoscopic surgery have translated into smaller incisions and shorter recovery. Since the advent of laparoscopy, surgeons have been fueled to develop less invasive operative methods as feasible alternatives to traditional procedures. As techniques evolved and technology advanced, laparoscopy became more widely accepted and is now more commonly used in many institutions. Recently, a trend toward less invasive surgery, driven by patient and surgeon alike, has been a major objective for many institutions because of the ability of laparoscopic surgery to reduce postoperative pain, achieve a quicker recovery time, and improve cosmetic outcomes. Although still evolving, traditional laparoscopy has served as a foundation for even further refinements in the minimally invasive approach and as a result, more advanced equipment and newer techniques have arisen

    Symptom distress remains a significant health problem among older adults with cancer following surgery. Understanding factors influencing older adults' symptom distress may lead to early identification and interventions, decreasing morbidity and improving outcomes. We conducted this study to identify factors associated with symptom distress following surgery among 326 community-residing patients 65 years or older with a diagnosis of thoracic, digestive, gynecologic, and genitourinary cancers. This secondary analysis used combined subsets of data from 5 nurse-directed intervention clinical trials targeting patients after surgery at academic cancer centers in northwest and northeastern United States. Symptom distress was assessed by the Symptom Distress Scale at baseline and at 3 and 6 months. A multivariable analysis, using generalized estimating equations, showed that symptom distress was significantly less at 3 and 6 months (3 months: P psychological, treatment, and function covariates. Thoracic cancer, comorbidities, worse mental health, and decreased function were, on average, associated with increased symptom distress (all P cancer, comorbidities, mental health, and function may influence older adults' symptom distress following cancer surgery. Older adults generally experience decreasing symptom distress after thoracic, abdominal, or pelvic cancer surgery. Symptom management over time for those with thoracic cancer, comorbidities, those with worse mental health, those with decreased function, and those 75 years or older may prevent morbidity and improve outcomes of older adults following surgery.

  15. The Role of Environmental Factors in Digestive Cancer

    Full Text Available The risk of digestive cancer in each country is analyzed in cancer registries for Incidence and Mortality. Survival is estimated from registries with a correct follow-up. Estimated values of Incidence and Mortality, expressed as an age standardized rate (ASR for 100 000 persons, for all the population of a country are also found in the WHO-IARC database Globocan, recently edited for the year 2008. At each site of digestive tumors, the variations between countries, in cancer incidence, mortality and survival, depend on the resources and the global health status of the country. Indeed environmental causal factors linked to lifestyle may have an increasing or decreasing impact on the risk of cancer. Such factors are classified on 3 categories: 1- nutrition plays a determinant role in colorectal cancer with a higher risk in countries with more resources and more calories in the diet. 2- Toxic agents like alcohol and tobacco increase the risk at all sites of digestive cancer; their role is preponderant in esophageal cancer. Aflatoxin, a food contaminant in tropical, less developed countries, increases the risk of liver cancer. 3 – Infectious agents play a major role with the Bacteria H.pylori for stomach cancer over the world, and the Hepatitis virus B and C for liver cancer in less developed countries of Africa and Asia. The control of carcinogenic causal environmental factors is included in the primary prevention of digestive cancer.

    Minimally invasive surgery for gastric cancer is a relatively new research field, with convincing results mostly stemming from Asian countries. The use of the robotic surgery platform, thus far assessed as a safe procedure, which is also easier to learn, sets the background for a wider spread of minimally invasive technique in the treatment of gastric cancer. This review will cover the literature published so far, analyzing the pros and cons of robotic surgery and highlighting the remaining study questions. PMID:26798433

  20. Gut microbiota and bacterial translocation in digestive surgery: the impact of probiotics.

    2017-05-01

    It is conceivable that manipulation of the gut microbiota could reduce the incidence or magnitude of surgical complications in digestive surgery. However, the evidence remains inconclusive, although much effort has been devoted to randomized controlled trials (RCTs) and meta-analyses on probiotics. Furthermore, the mechanism behind the protective effects of probiotics appears elusive, our understanding of probiotic actions being fragmentary. The objective of this review is to assess the clinical relevance of the perioperative use of probiotics in major digestive surgery, based on a comprehensive view of the gut microbiota, bacterial translocation (BT), and host defense system. The first part of this article describes the pathophysiological events associated with the gut microbiota. Results of RCTs for the perioperative use of probiotics in major digestive surgery are reviewed in the latter part. The development of the structural and functional barrier to protect against BT primarily results from the generally cooperative interactions between the host and resident microbiota. There is a large body of evidence indicating that probiotics, by enhancing beneficial interactions, reinforce the host defense system to limit BT. The perioperative use of probiotics in patients undergoing hepatobiliary and pancreatic surgery is a promising approach for the prevention of postoperative infectious complications, while the effectiveness in colorectal surgery remains controversial due to substantial heterogeneity among the RCTs with small sample populations. Further studies, such as multi-center RCTs with a larger sample size, are necessary to confirm the clinical relevance of probiotic agents in major digestive surgery.

  1. Cancer surgery: risks and opportunities.

    Coffey, J C

    2012-02-03

    In the recent past, several papers have pointed to the possibility that tumour removal generates a permissive environment in which tumour growth is potentiated. This phenomenon has been coined "perioperative tumour growth" and whilst it represents a departure in terms of our attitude to the surgical process, this concept was first hinted at by Paget(1) himself. Despite this, the time interval immediately before and after cancer surgery (i.e. the perioperative period) remains an underutilised interval during which chemotherapeutic regimens are rarely implemented. Herein, we present a summarised review of the literature that supports the concept that tumour removal may potentiate the growth of residual neoplastic disease. We also outline current knowledge regarding underlying mechanisms and in this manner highlight potential therapeutic entry points. Finally, we emphasise the urgent need for trials of agents that could protect patients against the harmful host-tumour interactions that may occur during the perioperative period.

    Surgery is the mainstay curative treatment in most cancer. We aimed to test the new hypothesis that cancer surgery performed during holiday periods is associated with worse long-term prognosis than for non-holiday periods. This nationwide Swedish population-based cohort study included 228,927 patients during 1997-2014 who underwent elective resectional surgery for a cancer where the annual number of resections was over 100. The 16 eligible cancer sites were grouped into 10 cancer groups. The exposure, holiday periods, was classified as wide (14-weeks) or narrow (7-weeks). Surgery conducted inside versus outside holiday periods was compared regarding overall disease-specific (main outcome) and overall all-cause (secondary outcome) mortality. Cox regression provided hazard ratios (HR) with 95% confidence intervals (CI) adjusted for age, sex, comorbidity, hospital volume, calendar period and tumor stage. Surgery conducted during wide and narrow holiday periods were associated with increased HRs of disease-specific mortality for cancer of the breast (HR 1.08, 95% CI 1.03-1.13 and HR 1.06, 95% CI 1.01-1.12) and possibly of cancer of the liver-pancreas-bile ducts (HR 1.09, 95% CI 0.99-1.20 and HR 1.12, 95% CI 0.99-1.26). Sub-groups with cancer of the colon-rectum, head-and-neck, prostate, kidney-urine bladder and thyroid also experienced statistically significantly worse prognosis following surgery conducted during holiday periods. No influence of surgery during holiday was detected for cancer of the esophagus-stomach, lung or ovary-uterus. All-cause HRs were similar to the disease-specific HRs. The prognosis following cancer surgery might not be fully maintained during holiday periods for all cancer sites. © 2017 UICC.

    Many veterans undergo cancer surgery outside of the Veterans Health Administration (VHA). We assessed to what extent these patients obtained care in the VHA before surgery. VHA-Medicare data, VHA administrative data, and Veterans Affairs Central Cancer Registry data. We identified patients aged ≥65 years in the VHA-Medicare cohort who underwent lung or colon cancer resection outside the VHA and assessed VHA visits in the year before surgery. Over 60% of patients in the VHA-Medicare cohort who received lung or colon cancer surgeries outside the VHA did not receive any care in VHA before surgery. Veterans' receipt of major cancer surgery outside the VHA probably reflects usual private sector care among veterans who are infrequent VHA users. © Health Research and Educational Trust.

    Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

    Digestive system cancers-those of the esophagus, stomach, small intestine, colon-rectum, liver, and pancreas-are highly related to genetics and lifestyle. Most are considered highly mortal due to the frequency of late diagnosis, usually in advanced stages, caused by the absence of symptoms or masked by other pathologies. Different tools are being investigated in the search of a more precise diagnosis and treatment. Plant lectins have been studied because of their ability to recognize and bind to carbohydrates, exerting a variety of biological activities on animal cells, including anticancer activities. The present report integrates existing information on the activity of plant lectins on various types of digestive system cancers, and surveys the current state of research into their properties for diagnosis and selective treatment.

    Full Text Available Abstract Background Seroma formation is the most frequent postoperative complication after breast cancer surgery. We carried out a study to investigate the effect of various demographic, clinical and therapeutic variables on seroma formation. Patients and methods A retrospective cross sectional study of patients who underwent surgical therapy for breast cancer with either modified radical mastectomy (MRM or breast preservation (BP was carried out. The demographic data and clinical information were extracted from case records. Seroma formation was studied in relation to age, type of surgery, tumor size, nodal involvement, preoperative chemotherapy, surgical instrument (electrocautery or scalpel, use of pressure garment, and duration of drainage. The multiple logistic regression analysis was performed to estimate odds ratios. Results A total of 158 patients with breast cancer were studied. The mean age of the patients was 46.3 years (SD ± 11.9. Seventy-three percent underwent modified radical mastectomy and the remaining 27% received breast preservation surgery. Seroma occurred in 35% of patients. In multivariate logistic regression analysis an association of postoperative seroma formation was noted with modified radical mastectomy (OR = 2.83, 95% CI 1.01–7.90, P = 0.04. No other factor studied was found to significantly effect the seroma formation after breast cancer surgery. Conclusion The findings suggest that the type of surgery is a predicting factor for seroma formation in breast cancer patients.

    Full Text Available BackgroundDepending on the initial pathology, hypovolemia, intra-abdominal hypertension, and sepsis are often encountered in neonatal digestive surgery. Accurate newborn monitoring during and after surgery is essential to adapt resuscitation protocols. Near infrared spectroscopy (NIRS is non-invasive and can detect hypoperfusion which indicates a low circulatory blood flow, regardless of the cause.ObjectiveEvaluating changes in cerebral and renal regional oxygen saturation during neonatal digestive surgeries, conducted according to normal practices, with commonly used monitoring parameters. Analyzing retrospectively the inter-relationships between NIRS values and mean arterial pressure (MAP values as well as pre-ductal SpO2.MethodsProspective, descriptive, monocentric study. All neonates referred for surgery were included. NIRS allows the measurement of cerebral and renal oxygenation fluctuations, as well as calculating difference in intraoperative and postoperative values.ResultsNineteen patients were included. Cerebral regional oxygen saturation (C rSO2 values were stable while renal regional oxygen saturation (R rSO2 values tended to decrease with time during surgery. Indeed, 72% of rSO2 decline episodes occurred after the first 30 min of surgery, without any significant statistical differences for the next 90 min of surgery. After surgery, the lowest average C and R rSO2 values were evidenced during the first 6 h, with 60% of C rSO2 and R rSO2 anomalies occurring in that time frame. There was no significant statistical difference observed in the following 18 h. There was a significant correlation between R rSO2 and SpO2 values (p < 0.01, but not with C rSO2 values. There was no correlation with the MAP either for the C rSO2 values or R rSO2 ones.ConclusionNIRS is a promising non-invasive bedside tool to monitor cerebral and tissue perfusion, analyzing tissue microcirculation. NIRS has its interest to guide neonatal digestive

    Conservative breast cancer surgery is facing a new problem: the potential tumour involvement of resection margins. This eventuality has been closely and negatively associated with disease-free survival. Various factors may influence the likelihood of margins being affected, mostly related to the characteristics of the tumour, patient or surgical technique. In the last decade, many studies have attempted to find predictive factors for margin involvement. However, it is currently the new techniques used in the study of margins and tumour localisation that are significantly reducing reoperations in conservative breast cancer surgery.

    A summary is done on the indication of oophorectomy - by surgery or radiation - in the treatment of breast cancer. Prophylactic - and therapeutic oophorectomy are analysed. It is concluded that the treatment of advanced cancer is a fight against time, once the survival of patients ought to be prolonged with the minor number of therapeutic agents, avoiding the usage of them all at once not to exaust them. Castration performed with therapeutic purposes in pre-or post-menopause patients with hyperestrogenism is the first link in the chain of paliative treatment of advanced breast cancer. (M.A.) [pt

    In the current age of minimally invasive surgery, laparoscopic surgery for colon cancer has been established as oncologically equivalent to conventional open surgery. The advantages of laparoscopic surgery have translated into smaller incisions and shorter recovery. Since the advent of laparoscopy, surgeons have been fueled to develop less invasive operative methods as feasible alternatives to traditional procedures. As techniques evolved and technology advanced, laparoscopy became more widely accepted and is now more commonly used in many institutions. Recently, a trend toward less invasive surgery, driven by patient and surgeon alike, has been a major objective for many institutions because of the ability of laparoscopic surgery to reduce postoperative pain, achieve a quicker recovery time, and improve cosmetic outcomes. Although still evolving, traditional laparoscopy has served as a foundation for even further refinements in the minimally invasive approach and as a result, more advanced equipment and newer techniques have arisen.

    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

    Full Text Available Background and objective Fast track surgery (FTS is a systematical method to accelerate the recovery of surgical patients by reducing the physical and mental trauma stress of them. The research is to investigate the feasibility of FTS application in lung cancer surgery. Methods A total of 80 cases of lung cancer patients with single leaf lobotomy resection were randomized into two groups. While the experimental group was treated with the conception of FTS, and the control group was treated with the traditional methods. The incident rate of post-operation pain degrees, telecasts, pleural effusion, the post-operation time stay in hospital time and the total cost during hospitalization in two groups were compared respectively. Results In FTS group: the VAS score of post-operation pain at 1 h, 6 h, 12 h, 24 h and 48 h all significantly decreased compared to the traditional therapy group. The incidence rate of telecast was 10.53%. The incidence rate of pleural effusion was 26.31%. The length of stay after operation was (4±1 d and the total cost was RMB 15 600±7 600. In the control group, the above values were 77.78%, 33.33%, 22.22%, (9±1 d, RMB 23 600±5 400, respectively. The post operation pain (VAS method of FTS group was remarkablely below the control group. There has significant difference of the incident rate of telecasts, stay time in hospital and the total cast in two groups (P < 0.05. No significant difference was observed in the incident rate of pleural effusion. Conclusion The new methods of FTS can apparently accelerates recovery after lung cancer resection, reduces complications, shorten timestay in hospital and cut down the total cost.

  2. Irradiation and surgery for selected cancers

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

    To compare pre- and post-operative shoulder active range of motion (AROM) values from female breast cancer survivors to population norm values for shoulder AROM; and to compare shoulder AROM differences pre- and post-surgery between female African American and White breast cancer survivors (BCA). This pilot study used a convenience sample and longitudinal design measuring participants 2 times (T0 = baseline, after biopsy but within 2 weeks before BCA surgery; T1 = 2 nd postoperative week). The U.S. has the largest BCA survivor population in history and yet the mortality burden remains highest among AA BCA survivors. AAs may also have greater burden of physical and functional side effects compared to whites and the general population. The data were collected from a convenience sample (n = 33; n AA = 9, n W = 24) and included data on shoulder AROM, medical chart review for pre- and co-morbid conditions, and self-reported demographics and medical history. We used t-tests to compare sample AROM means to population norms. We then compared our sample across 2 timepoints (T0 = pre-surgery; T1 = 2 weeks post-surgery) using independent samples t-tests and repeated measures analysis of variance (p shoulder abduction (at T0) and flexion (at T1) than whites. However, 100% had significantly reduced AROM for all movements at T0 (prior to surgery but after biopsy) when compared to population norms. The significant reduction in shoulder AROM after biopsy but before surgery points to a possible unmet need for early physical therapy intervention. Further research using randomized controlled trial design is recommended.

    The aim of the present study was to estimate the incisional recurrence (IR) rate after endometrial cancer (EC) staging surgery and analyze characteristics of affected patients. We retrospectively searched for patients with EC at 2 institutions and analyzed the occurrence of IR after open, laparoscopic, or robotic surgery. Additionally, a review of the literature was performed. Out of 2,636 patients with EC, 1,732 (65.7%), 461 (17.5%), and 443 (16.8%) had open, laparoscopic, and robotic surgery, respectively. Only 3 patients (0.11%) had IR, all after open surgery. Additionally, 38 cases of IR were identified from the literature. Patients with non-isolated IR had worse overall survival than patients with isolated IR (p=0.04). Among this latter group, combined treatments may be associated with improved survival outcome. IR after EC surgery is rare and may occur after minimally-invasive or open operations. Combination of local and systemic treatments may provide favorable outcomes for patients with isolated IR.

    The digestive system cancers are leading cause of cancer-related death worldwide, and have high risks of morbidity and mortality. More and more long non-coding RNAs (lncRNAs) have been studied to be abnormally expressed in cancers and play a key role in the process of digestive system tumour progression. Plasmacytoma variant translocation 1 (PVT1) seems fairly novel. Since 1984, PVT1 was identified to be an activator of MYC in mice. Its role in human tumour initiation and progression has long been a subject of interest. The expression of PVT1 is elevated in digestive system cancers and correlates with poor prognosis. In this review, we illustrate the various functions of PVT1 during the different stages in the complex process of digestive system tumours (including oesophageal cancer, gastric cancer, colorectal cancer, hepatocellular carcinoma and pancreatic cancer). The growing evidence shows the involvement of PVT1 in both proliferation and differentiation process in addition to its involvement in epithelial to mesenchymal transition (EMT). These findings lead us to conclude that PVT1 promotes proliferation, survival, invasion, metastasis and drug resistance in digestive system cancer cells. We will also discuss PVT1's potential in diagnosis and treatment target of digestive system cancer. There was a great probability PVT1 could be a novel biomarker in screening tumours, prognosis biomarkers and future targeted therapy to improve the survival rate in cancer patients. © 2017 John Wiley & Sons Ltd.

    Accumulating evidence indicates that common carcinogenic pathways may underlie digestive system cancers. Physical activity may influence these pathways. Yet, to our knowledge, no previous study has evaluated the role of physical activity in overall digestive system cancer risk. To examine the association between physical activity and digestive system cancer risk, accounting for amount, type (aerobic vs resistance), and intensity of physical activity. A prospective cohort study followed 43 479 men from the Health Professionals Follow-up Study from 1986 to 2012. At enrollment, the eligible participants were 40 years or older, were free of cancer, and reported physical activity. Follow-up rates exceeded 90% in each 2-year cycle. The amount of total physical activity expressed in metabolic equivalent of task (MET)-hours/week. Incident cancer of the digestive system encompassing the digestive tract (mouth, throat, esophagus, stomach, small intestine, and colorectum) and digestive accessory organs (pancreas, gallbladder, and liver). Over 686 924 person-years, we documented 1370 incident digestive system cancers. Higher levels of physical activity were associated with lower digestive system cancer risk (hazard ratio [HR], 0.74 for ≥63.0 vs ≤8.9 MET-hours/week; 95% CI, 0.59-0.93; P value for trend = .003). The inverse association was more evident with digestive tract cancers (HR, 0.66 for ≥63.0 vs ≤8.9 MET-hours/week; 95% CI, 0.51-0.87) than with digestive accessary organ cancers. Aerobic exercise was particularly beneficial against digestive system cancers, with the optimal benefit observed at approximately 30 MET-hours/week (HR, 0.68; 95% CI, 0.56-0.83; P value for nonlinearity = .02). Moreover, as long as the same level of MET-hour score was achieved from aerobic exercise, the magnitude of risk reduction was similar regardless of intensity of aerobic exercise. Physical activity, as indicated by MET-hours/week, was inversely associated with the risk of

    Full Text Available Gastric cancer is one of the most common causes of cancer-related death. It requires multimodal treatment and surgery is the most effective treatment modality. Radical surgery includes total or subtotal gastrectomy with lymph node dissection. The extent of lymphadenectomy still remains controversial. Eastern surgeons have performed D2 or more extended lymphadenectomy while their Western colleagues have performed more limited lymph node dissection. However, the trend has been changing in favour of D2 lymph node dissection in both hemispheres. Currently, D2 is the recommended type of lymphadenectomy in experienced centres in the west. In Japan, D2 lymph node dissection is the standard surgical approach. More extensive lymphadenectomy than D2 has not been found to be associated with improved survival and generally is not performed. Bursectomy and splenectomy are additional controversial issues in surgical performance, and trends regarding them will be discussed. The performance of bursectomy is controversial and there is no clear evidence of its clinical benefit. However, a trend toward better survival in patients with serosal invasion has been reported. Routine splenectomy as a part of lymph node dissection has largely been abandoned, although splenectomy is recommended in selected cases. Minimally invasive surgery has gained wide popularity and indications for minimally invasive procedures have been expanding due to increasing experience and improving technology. Neoadjuvant therapy has been shown to have beneficial effects and seems necessary to provide a survival benefit. Diagnostic laparoscopy should be kept in mind prior to treatment

    The history of pancreatic cancer surgery, though fraught with failure and setbacks, is punctuated by periods of incremental progress dependent upon the state of the art and the mettle of the surgeons daring enough to attempt it. Surgical anesthesia and the aseptic techniques developed during the latter half of the 19(th) century were instrumental in establishing a viable setting for pancreatic surgery to develop. Together, they allowed for bolder interventions and improved survival through the post-operative period. Surgical management began with palliative procedures to address biliary obstruction in advanced disease. By the turn of the century, surgical pioneers such as Alessandro Codivilla and Walther Kausch were demonstrating the technical feasibility of pancreatic head resections and applying principles learned from palliation to perform complicated anatomical reconstructions. Allen O. Whipple, the namesake of the pancreaticoduodenectomy (PD), was the first to take a systematic approach to refining the procedure. Perhaps his greatest contribution was sparking a renewed interest in the surgical management of periampullary cancers and engendering a community of surgeons who advanced the field through their collective efforts. Though the work of Whipple and his contemporaries legitimized PD as an accepted surgical option, it was the establishment of high-volume centers of excellence and a multidisciplinary approach in the later decades of the 20(th) century that made it a viable surgical option. Today, pancreatic surgeons are experimenting with minimally invasive surgical techniques, expanding indications for resection, and investigating new methods for screening and early detection. In the future, the effective management of pancreatic cancer will depend upon our ability to reliably detect the earliest cancers and precursor lesions to allow for truly curative resections.

    Our objective was to assess a laparoscopic training model for general surgery residents. Twelve general surgery residents carried out a training program, consisting of a theoretical session (one hour) and a hands-on session on simulator (7 h) and on animal model (13 h). For the first and last repetitions of simulator tasks and the Nissen fundoplication technique, time and scores from the global rating scale objective structured assessment of technical skills (OSATS) were registered. Before and after the course, participants performed 4 tasks on the virtual reality simulator LAPMentor™: 1) hand-eye coordination, 2) hand-hand coordination, 3) transference of objects and 4) cholecystectomy task, registering time and movement metrics. Moreover, the residents completed a questionnaire related to the training components on a 5-point rating scale. The last repetition of the tasks and the Nissen fundoplication technique were performed faster and with a higher OSATS score. After the course, the participants performed all LAPMentor™ tasks faster, increasing the speed of movements in all tasks. Number of movements decreased in tasks 2, 3 and 4; as well as path length in tasks 2 and 4. Training components were positively rated by residents, being the suture task the aspect best rated (4.90 ± 0.32). This training model in digestive laparoscopic surgery has demonstrated to be valid for the improvement of basic and advanced skills of general surgery residents. Intracorporeal suturing and the animal model were the best rated training elements. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    When total mesorectal excision (TME) is accurately performed, dysfunction, theoretically, does not occur. However, there are differences among individuals in the running patterns and the volumes of nerve fibers, and if obesity or a narrow pelvis is present, nerve identification is difficult. Currently, the rate of urinary dysfunction after rectal surgery ranges from 33% to 70%. Many factors other than nerve preservation play a role in minor incontinence. Male sexual function shows impotence rates ranging from 20% to 46%, while 20%-60% of potent patients are unable to ejaculate. In women, information on sexual function is not easily obtained, and there are more unknown aspects than in men. As urinary, sexual, and defecation dysfunction due to adjuvant radiotherapy have been reported to occur at a high frequency, the creation of a protocol that enables analysis of long-term functional outcome will be essential for future clinical trials. In the treatment of rectal cancer, surgeon-related factors are extremely important, not only in achieving local control but also in preserving function. This article reviews findings from recent studies investigating urinary, sexual, and defecation dysfunction after rectal cancer surgery and discusses questions to be studied in the future. (author)

    Objective: To study the clinical characteristics, strategy of treatment and prognosis of multiple primary cancers(MPC) diagnosed of digestive system malignant tumor firstly. Methods: From January, 2000 to December, 2015, the clinical, follow-up and prognostic data of 138 MPC patients diagnosed of digestive system malignant tumor firstly were retrospectively analyzed. Results: 138 cases were found in 10 580 cases with malignant tumors, and the incidence was 1.30%. There were 129 cases of duplex primary cancers, 8 cases of triple primary cancers and 1 case of quintuple primary cancers. The repetitive primary cancer was occurred in digestive system (61cases, 44.2%) most frequently, with the next in respiratory system (46 cases, 33.3%). 52.2% (72 cases) suffered second primary cancer in 2 years after first primary cancer diagnosed, and 75.4% (104 cases) in 5 years. The median overall survival in patients with all cancer lesions radically treated was 168 months, better than any other treatment (68 months, P digestive system malignant tumor most frequently occurred in the digestive system and respiratory system. More concern should be attracted in follow-up, especially in the first 5 years. The key to improve patient' prognosis was radical treatment to every primary cancer.

    The Xeroderma pigmento-sum group D gene (XPD) plays a key role in nucleotide excision repair. Single nucleotide polymorphisms (SNP) located in its functional region may alter DNA repair capacity phenotype and cancer risk. Many studies have demonstrated that XPD polymorphisms are significantly associated with digestive tract cancers risk, but the results are inconsistent. We conducted a comprehensive meta-analysis to assess the association between XPD Lys751Gln polymorphism and digestive tract cancers risk. The digestive tract cancers that our study referred to, includes oral cancer, esophageal cancer, gastric cancer and colorectal cancer. We searched PubMed and EmBase up to December 31, 2012 to identify eligible studies. A total of 37 case-control studies including 9027 cases and 16072 controls were involved in this meta-analysis. Statistical analyses were performed with Stata software (version 11.0, USA). Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association. The results showed that XPD Lys751Gln polymorphism was associated with the increased risk of digestive tract cancers (homozygote comparison (GlnGln vs. LysLys): OR = 1.12, 95% CI = 1.01-1.24, P = 0.029, P heterogeneity = 0.133). We found no statistical evidence for a significantly increased digestive tract cancers risk in the other genetic models. In the subgroup analysis, we also found the homozygote comparison increased the susceptibility of Asian population (OR = 1.28, 95% CI = 1.01-1.63, P = 0.045, P heterogeneity = 0.287). Stratified by cancer type and source of control, no significantly increased cancer risk was found in these subgroups. Additionally, risk estimates from hospital-based studies and esophageal studies were heterogeneous. Our meta-analysis suggested that the XPD 751Gln/Gln genotype was a low-penetrate risk factor for developing digestive tract cancers, especially in Asian populations.

    Full Text Available Introduction: Breast cancer is responsible for 25% of all cancers and is the most prevalent in the female population. Due to treatment advances and early diagnoses, survival rates have improved, however this condition impacts work absenteeism due to the productive age of these women. The main factors responsible for work absenteeism are physical complications due to surgical treatment. Objective: The aim of this study is to investigate the effects of surgical breast cancer treatments on occupation, to characterize the degree of work absenteeism and to investigate the type of relation between surgical technique and absenteeism’s main causes. Method: Cross-sectional study with 74 women diagnosed with breast cancer. A semi-structured interview was used to collect information regarding surgical and clinical aspects, sociodemographic data, work behavior and physical therapy treatments. The data was organized on Microsoft Excel and analyzed by frequency and chi-squared test. The significance level considered was p ≤ 0.05. Results: Breast cancer was most common on the left side (51%, Madden modified radical mastectomy was the most common (50% and lymph node resection was present in 93.2% of cases. The most frequent post-surgery complications were pain, problems with scarring, sensitivity alterations, ROM limitation, lymphedema and seroma. Only 58% of women were treated with physical therapy and 60% withdrew from professional activities, 23% abandoned work, 26% changed their work role and 14% retired due to the disease. Conclusion: The present study suggests the existence of a direct relation between treatment and work absenteeism.

  19. Application of NMR-CT for the staging of cancer of the digestive organs

    1986-01-01

    To assess the potential of NMR-CT for demonstrating cancer of the digestive organs, we examined a total of 232 patients (89 with esophageal cancer, 52 with liver cancer, 40 with colorectal cancer, 9 with pancreatic cancer, 9 with gastric cancer, and 33 with other diseases). Our machine is a Picker International NMR-CT using a superconducting magnet of 0.256 tesla. 1. Diagnosis of lymph node involvement of esophageal cancer. Using only the coronal plane, each patient was scanned by the spin echo technique (TE = 40, TR = 400) from the plane of the descending aorta to the plane of the trachea 1 cm in thickness, at 1 cm intervals, continuously. Lymph nodes were identified as intense grey masses in fat tissue of high intensity. Twenty cases were proved by surgery or autopsy, and it was possible to assess 160 lymph-node groups. A total of 25 patients were imaged as having positive lymph nodes, but 17 of them had metastasis-positive nodes. In other 135 nodes imaged as negative lymph nodes, only two had metastasis and 133 were negative for metastasis. Overall accuracy was 93.8 %. 2. Diagnosis of liver cancer. Intrahepatic vessels were clearly imaged without using contrast enhancement in NMR-CT, so it was easy to diagnose the segment containing the tumor and to detect tumor emboli in the portal vein. The capsule was imaged in 84 % (16/19) using IR techniques, although only 37 % (7/19) could be imaged by X-CT. 3. Diagnosis of colorectal cancer. Using the sagittal plane, the sacrum, urinary bladder and other organs were imaged better parallel to their axis, so that the relationship between rectal cancer and surrounding organs could be clearly visualised with NMR-CT. With regard to lymphatic metastasis, coronal imaging was useful for picturing mesenteric and pelvic vessels, so that lymph nodes were imaged as low-intensity masses along the vessels. Lymph metastasis almost 1 cm size can be detected using coronal NMR-CT. (J.P.N.)

    Elemental composition study of digestive cancer tissue with different localizations (esophagus, stomach, colon) by using PIXE analysis is presented. A number of 20 tumor and normal (control) tissue samples were analyzed. Thin targets were prepared by mineralization of the lyophilized tissue with nitric acid and dropping on 2 μm Mylar foil. The measurements were carried out in vacuum using 3 MeV protons delivered by the tandem accelerator in Bucharest, Romania. The following elements were identified: S, Cl, K, Ca, Cr, Mn, Fe, Cu and Zn. Although the results show relatively large variations from a sample to another there were obtained mean ratios of tumor/normal concentrations which are significantly greater than one, in the limit of the standard deviation for the following elements: K (1.45±0.28), Ca (1.30±0.21), Cr (2.33±0.56), and Zn (1.18±0.15). For the other determined elements, no significant difference between the tumor and normal tissues, in the limit of the present standard deviation, was found. (authors)

    Morbid obesity is a worldwide health concern that compromises life quality and health status of obese human subjects. Bariatric surgery for treating morbid obesity remains as one of the best alternatives to promote excess weight loss and to reduce co-morbidities. We have not found studies reporting nutrients and energy balance considering digestibility trials in humans following surgery. The purpose of this study was to determine protein, lipid, fiber, energy, calcium, and phosphorous digestibility in a swine model that underwent ileal transposition (IT), sleeve gastrectomy with ileal transposition (SGIT), Roux-en-Y gastric bypass (RYGBP), and with sham operated animals (SHAM). Thirty-two pigs were randomly assigned to four laparoscopic procedures: IT (n = 8), RYGBP (n = 8), SGIT (n = 8), and Sham-operated pigs (n = 8). From day 0 postsurgery to 130, pigs were weighed monthly to determine live weight and weight gain was calculated for each month postsurgery until day 130. Food intake in a metabolic weight basis was calculated by measuring ad libitum food intake at day 130. Swine were fitted into metabolic crates to determine digestibility coefficients of dry matter, protein, fat, fiber, ash, energy, calcium, and phosphorous from day 130. A one-way ANOVA and Student-Newman-Keuls were used to detect differences in weight, food intake, and digestibility coefficients. Digestibility values for dry matter, fiber, phosphorus, and energy showed no differences among groups (P > 0.05). However, significant differences (P ≤ 0.05) were encountered among groups for fat, protein, ash, and calcium digestibilities. The RYGBP procedure, when applied to the pig model, significantly reduced calcium, fat, and ash digestibility, which did not occur with SGIT or IT procedure, when compared with Sham-operated animals. © 2015 by the Society for Experimental Biology and Medicine.

    To explore the detection of five tumor markers by trypsin digestion of sputum in the diagnosis of lung cancer, the samples of sputum in patients with lung cancer and benign lung disease were digested by trypsin and used to measure five tumor markers. The results showed that the sputum were well digested by 6% trypsin at pH8 and no affect on the determination of tumor markers. The CEA, CA125, CA153, CA211 and NSE levels in lung cancer group were significantly higher than that of in benign group (P<0.05). The sputum CEA and CA125 levels were significantly higher than that of the serum levels (P<0.05). The detection of sputum CEA, CA125, CA153, CA211 and NSE levels have clinical value in the diagnosis of lung cancer. When combined with other diagnostic methods,it might be helpful for further diagnosis in non confirmed lung cancer patients. (authors)

    Full Text Available Erectile dysfunction is the most common complication after pelvic radical surgery. Rehabilitation programs are increasingly being used in clinical practice but there is no high level of evidence supporting its efficacy. The principle of early penile rehabilitation stems from animal studies showing early histological and molecular changes associated with penile corporal hypoxia after cavernous nerve injury. The concept of early penile rehabilitation was developed in late nineties with a subsequent number of clinical studies supporting early pharmacologic penile rehabilitation. These studies included all available phosphodiesterase type 5 inhibitors, intracavernosal injection and intraurethral use of prostaglandin E1 and to lesser extent vacuum erectile devices. However, these studies are of small number, difficult to interpret, and often with no control group. Furthermore, no studies have proven an in vivo derangement of endothelial or smooth muscle cell metabolism secondary to a prolonged flaccid state. The purpose of the present report is a synthetic overview of the literature in order to analyze the concept and the rationale of rehabilitation program of erectile dysfunction following radical pelvic surgery and the evidence of such programs in clinical practice. Emphasis will be placed on penile rehabilitation programs after radical cystoprostatectomy, radical prostatectomy, and rectal cancer treatment. Future perspectives are also analyzed.

    We aimed to compare the difference in case fatality rate between more developed and very high Human Development Index (HDI) regions, less developed and low HDI regions, and Romania. The incidence and mortality rates for digestive cancers were obtained from the IARC/WHO 2012 database. World mean mortality-to-incidence ratios registered the highest values in pancreatic cancer (0.97/0.94), and liver cancer (0.93/0.96) in males/females, respectively. The lowest values were recorded in colorectal cancer (0.48 in both sexes). Mortality-to-incidence ratios were generally higher in less developed areas, low HDI populations, and in Romania. The difference in case fatality rate between different areas showed higher variations for colorectal, gastric and gallbladder cancers, and smaller variations for esophageal, liver, and pancreatic cancers. In summary, mortality-to-incidence ratios of digestive cancers were high in 2012; higher values were registered in less developed and low HDI regions, and in Romania. Mortality-to-incidence ratios were similar in both sexes, even though the incidence was generally higher in men. Digestive cancer mortality variation suggests the necessity of finding better strategies for prevention, early diagnosis and treatment of digestive cancers.

    The albumin/globulin ratio (AGR) has been widely reported to be a potential predictor of prognosis in digestive system cancers (DSCs), but convincing conclusions have not been made. Therefore, herein, we performed a meta-analysis of relevant studies regarding this topic to evaluate the prognostic value of AGR in patients with DSCs. Three databases, including PubMed, EMBase, and Web of science, were searched comprehensively for eligible studies through September 8, 2017. The outcomes of interest included overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). In our meta-analysis, pooled analysis of 13 studies with 9269 patients showed that a low AGR was significantly correlated with poor OS (HR = 1.94; 95% CI: 1.57-2.38; P digestive system cancers. A low pretreatment AGR may be a useful predictive prognostic biomarker in human digestive system cancers.

    Hypoxia is an all but ubiquitous phenomenon in cancers. Two known hypoxia-inducible factors (HIFs), HIF-1α and HIF-2α, primarily mediate the transcriptional response to hypoxia. Despite the high homology between HIF-1α and HIF-2α, emerging evidence suggests differences between both molecules in terms of transcriptional targets as well as impact on multiple physiological pathways and tumorigenesis. To date, much progress has been made toward understanding the roles of HIF-2α in digestive system cancers. Indeed, HIF-2α has been shown to regulate multiple aspects of digestive system cancers, including cell proliferation, angiogenesis and apoptosis, metabolism, metastasis and resistance to chemotherapy. These findings make HIF-2α a critical regulator of this malignant phenotype. Here we summarize the function of HIF-2 during cancer development as well as its contribution to tumorigenesis in digestive system malignancies.

    The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, Pstudy showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

    Traditional Chinese medicine (TCM) is commonly provided to cancer patients, however, the patterns of prescriptions for this type of medicine in Taiwan are unclear. This study aimed to evaluate the use of traditional Chinese medicine products in colon cancer patients post-surgery in Taiwan and to research patterns of TCM. This was a cross-sectional study of newly diagnosed colon cancer patients who received surgery between 2004 and 2008 identified from the National Health Insurance Research Database of Taiwan. The prescription patterns and reasons for the use of TCM for colon cancer were analyzed. The results showed that "symptoms, signs and ill-defined conditions" (23.3%) and diseases of the digestive system (16.9%) were the most common reasons for using Chinese herbal medicine. Xiang-sha-liu-jun-zi-tang (7.1%), Bu-zhong-yi-qi-tang (4.3%), Jia-wei-xiao-yao-san (4.1%), Shen-Ling-Bai-Zhu-San (3.7%), Ban-Xia-Xie-Xin-Tang (3.4%), Gui-pi-tang (2.4%), Ping-Wei-San (2.4%), Gan-Lu-Yin (2.0%), Bao-He-Wan (1.9%), and Zhen-Ren-Huo-Ming-Yin (1.8%) were the most commonly prescribed single Chinese herbal formulae (CHF) for colon cancer patients post-surgery. Hedyotis diffusa Willd (Bai Hua She She Cao) (5.1%) and Scutellaria barbata (Ban Zhi Lian )(4.8%) were the most commonly prescribed single Chinese herbs. This study identified patterns of TCM use in colon cancer patients post-surgery in Taiwan. The herbal ingredients were most commonly used for stimulate ghrelin secretion to increase food intake and had potential anti-tumor effect. However, further research is required to evaluate any beneficial effects which could identify leads for the development of new treatment strategies using TCM. Copyright © 2014 Elsevier Ireland Ltd.

    2016-01-21

    Best known for their anti-resorptive activity in bone, bisphosphonates (BPs) have generated interest as potential antineoplastic agents given their pleiotropic biological effects which include antiproliferative, antiangiogenic and immune-modulating properties. Clinical studies in multiple malignancies suggest that BPs may be active in the prevention or treatment of cancer. Digestive tract malignancies represent a large and heterogeneous disease group, and the activity of BPs in these cancers has not been extensively studied. Recent data showing that some BPs inhibit human epidermal growth factor receptor (HER) signaling highlight a potential therapeutic opportunity in digestive cancers, many of which have alterations in the HER axis. Herein, we review the available evidence providing a rationale for the repurposing of BPs as a therapeutic adjunct in the treatment of digestive malignancies, especially in HER-driven subgroups.

    Boston, Sarah; Henderson, Ralph A

    2014-09-01

    Surgery is a critical component in the treatment of most solid tumors in small animals. Surgery is increasingly combined with adjuvant therapies such as chemotherapy and radiation so surgeons who are treating cancer must have a good understanding of surgical oncology principles, cancer biology, and the roles and potential interactions of surgery, radiation, and chemotherapy. The sequencing plan for these modalities should be determined before treatment is initiated. The surgical oncologist must have a working knowledge of chemotherapy agents and radiation and the effect of these treatments on the ability of tissues to heal and the outcome for the patient.

    The role of BRCA1 and BRCA2 genes is mainly to maintain genome integrity in response to DNA damage through different mechanisms. Deregulation of BRCA1 and BRCA2 is associated with the development of tumor and altered sensitivity to chemotherapeutic agents. In this study, we determined protein expression of BRCA1 and BRCA2 in 4 digestive system cancers (gastric cancer, colorectal cancer, hepatocellular carcinoma, and pancreatic cancer) by immunohistochemistry on tissue microarrays. A total of 1546 samples of 4 types of cancer tissues, their matched adjacent nontumor tissues, and corresponding benign tissues were studied, respectively. Immunohistochemistry expression patterns of the 2 proteins and their correlation with patients' clinical parameters and overall survival were analyzed. The results showed that low expression of cytoplasmic BRCA1 and BRCA2 was commonly associated with advanced tumor-lymph node-metastasis stage, whereas high expression of nuclear BRCA1 was generally correlated with advanced tumor stages in these cancers. High expression of cytoplasmic BRCA1 and BRCA2 had significantly favorable overall survival in digestive system cancers; in contrast, BRCA1 nuclear expression usually predicted poor outcomes. We conclude that BRCA1 and BRCA2 could be used as clinicopathological biomarkers to evaluate the prognosis of digestive system cancers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), a newly discovered long non-coding RNA (lncRNA), has been reported to be overexpressed in various cancers. However, the clinical value of MALAT1 in digestive system cancers is unclear. This study was designed to investigate the potential value of MALAT1 as a prognostic biomarker in digestive system cancers. We searched the Medline, Embase and Cochrane Library databases. All studies that explored the correlation between lncRNA MALAT1 expression and survival in digestive system tumors were selected. A quantitative meta-analysis was performed for the correlation between lncRNA MALAT1 expression and survival in digestive system tumors. Five studies were eligible for analysis, which included 547 patients. Meta-analysis showed that high expression of MALAT1 could predict poor overall survival (OS) in digestive system cancers (pooled HR: 1.85, 95% CI: 1.41-2.43, Pdigestive system cancers.

    1979-01-01

    The metabolic response to uncomplicated surgery in the patient undergoing primary therapy for malignancy is no different than the response to surgery of similar magnitude for benign disease. Hemodynamic, nutritional-endocrine, and convalescent changes are similar. However, with current aggressive approaches to the management of cancer, the patient often comes to surgery with evidence of major debilitating side effects from his progressive malignancy or from aggressive multimodality therapy. The surgeon must be aware of the consequences of the use of combination therapies on the expected metabolic response to surgery. Awareness of such problems such as the nutritional deficit will allow preventive methods to supercede mtabolic salvage procedures

    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.

    Vagus nerve and recurrent laryngeal nerve (RLN) injury are not rare complications of lung cancer surgery and can cause lethal consequences. Until now, no optimal method other than paying greater attention during surgery has been available. Four patients underwent lung surgery that involved RLN or vagus nerve injury. The left RLN or vagus nerve was cut off and then reconstructed immediately during surgery. Two patients underwent direct anastomosis, while the remaining two underwent phrenic nerve replacing tension-relieving anastomosis. All patients were able to speak immediately after recovery. No or minimal glottal gap was observed during laryngoscopy conducted on the second day after surgery. Most patients achieved full recovery of voice quality. Immediate reconstruction of RLN is technically feasible and can be carried out with satisfying short-term and long-term outcomes. © 2018 The Authors.

    2016-09-21

    Management of cancers of the digestive system has progressed rapidly into the molecular era. Despite the significant recent achievements in the diagnosis and treatment of these patients, the number of deaths for these tumors has currently plateaued. Many investigations have assessed the role of HER2 in tumors of the digestive system in both prognostic and therapeutic settings, with heterogeneous results. Novel testing and treatment guidelines are emerging, in particular in gastric and colorectal cancers. However, further advances are needed. In this review we provide a comprehensive overview of the current state-of-knowledge of HER2 alterations in the most common tumors of the digestive system and discuss the operational implications of HER2 testing.

  9. Indications and contraindications for surgery in esophageal cancer

    Carriquiry, G.

    2004-01-01

    In this story we will present the main problems that we have as a surgeons at the moment to decide the indication for surgery in patients with esophageal cancer. Undoubtedly, the patient that will be submitted to surgery must have strict criteria in order to obtain good results. The patient must be compensated from respiratory, cardiovascular, hepatic and renal point of view with a (IMC) above 20, with Karnofsky index above 80% (wanders well), that declares the acceptance of surgery as well as the conserved appetite. After deciding the surgery according to the general conditions, should be discuss the type of procedure, based primarily on tumor topography, because there are different results both morbidity and long-term survival. The indications for resection or palliative surgery depend on the tumor stage. The indications for resection surgery with conventional or eventual extended lymphadenectomy require a patient in good condition, good experience the surgical team and a good hospital support. In tumor stage I the indication is a supposedly curative surgery. The tumor stages II b, III and IV are the heritage of palliative surgery, with or without tumor resection. The age is not an absolute contraindication for surgery, but the hypertension, liver cirrhosis, respiratory diseases with severe functional impact, ischemic heart disease, dilated heart with lowered LVEF, severe psychological disorders and the loss of appetite are contraindication. The morbidity and mortality has declined markedly due to technological advances and specialization of surgical groups, so that surgery is still the best treatment for selected patients

    The physiological changes that occur immediately following cancer surgeries initiate a chain of events that ultimately result in a short pro-, followed by a prolonged anti-, inflammatory period. Natural Killer (NK) cells are severely affected during this period in the recovering cancer patient. NK cells play a crucial role in anti-tumour immunity because of their innate ability to differentiate between malignant versus normal cells. Therefore, an opportunity arises in the aftermath of cancer surgery for residual cancer cells, including distant metastases, to gain a foothold in the absence of NK cell surveillance. Here, we describe the post-operative environment and how the release of sympathetic stress-related factors (e.g., cortisol, prostaglandins, catecholamines), anti-inflammatory cytokines (e.g., IL-6, TGF-β), and myeloid derived suppressor cells, mediate NK cell dysfunction. A snapshot of current and recently completed clinical trials specifically addressing NK cell dysfunction post-surgery is also discussed. In collecting and summarizing results from these different aspects of the surgical stress response, a comprehensive view of the NK cell suppressive effects of surgery is presented. Peri-operative therapies to mitigate NK cell suppression in the post-operative period could improve curative outcomes following cancer surgery.

    Purinergic signaling is important for many biological processes in humans. Purinoceptors P2Y are widely distributed in human digestive system and different subtypes of P2Y receptors mediate different physiological functions from metabolism, proliferation, differentiation to apoptosis etc. The P2Y receptors are essential in many gastrointestinal functions and also involve in the occurrence of some digestive diseases. Since different subtypes of P2Y receptors are present on the same cell of digestive organs, varying subtypes of P2Y receptors may have opposite or synergetic functions on the same cell. Recently, growing lines of evidence strongly suggest the involvement of P2Y receptors in the pathogenesis of several digestive diseases. In this review, we will focus on their important roles in the development of digestive inflammation and cancer. We anticipate that as the special subtypes of P2Y receptors are studied in depth, specific modulators for them will have good potentials to become promising new drugs to treat human digestive diseases in the near future.

    Full Text Available Minimally Invasive Single Site (MISS surgery is a better terminology to explain the novel concept of scarless surgery, which is increasingly making its way into clinical practice. But, there are some difficulties. We review the existing technologies for MISS surgery with regards to single-port devices, endoscope and camera, instruments, retractors and also the future perspectives for the evolution of MISS surgery. While we need to move ahead cautiously and wait for the development of appropriate technology, we believe that the "Ultimate form of Minimally Invasive Surgery" will be a hybrid form of MISS surgery and Natural Orifice Transluminal Endoscopic Surgery, complimented by technological innovations from the fields of robotics and computer-assisted surgery.

    2009-01-01

    Nearly half of breast cancer patients in developing countries present with a locally advanced cancer. Treatment is centered on a multimodal approach based on chemotherapy, surgery and radiotherapy. The growing use of neoadjuvant chemotherapy has led to a more conservative surgical approach; nonetheless, it is not yet considered as a standard. There are no clear recommendations on the use of a radiotherapy boost in such situation. A Medline search was developed. Most articles are retrospective series. Survival free of locoregional relapse in patients treated with neoadjuvant chemotherapy, breast conserving surgery and radiotherapy is good. All articles described a boost administered to nearly all patients without regard to their prognostic factors, given that a locally advanced tumor is already considered as a poor prognostic factor. Even tough the poor level of evidence, a recommendation can be made: radiotherapy boost should be administered to all patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and breast conserving surgery.

    Full Text Available Chong Han Pek,1 John Tey,2 Ern Yu Tan1 1Department of General Surgery, 2Department of Anaesthesiology, Intensive Care and Pain Medicine, Tan Tock Seng Hospital, Singapore, Singapore Abstract: Ambulatory breast cancer surgery is well accepted and is the standard of care at many tertiary centers. Rather than being hospitalized after surgery, patients are discharged on the day of surgery or within 23 hours. Such early discharge does not adversely affect patient outcomes and has the added benefits of better psychological adjustment for the patient, economic savings, and a more efficient utilization of health care resources. The minimal care needed post-discharge also means that the caregiver is not unduly burdened. Unplanned conversions to inpatient admission and readmission rates are low. Wound complications are infrequent and no issues with drain care have been reported. Because the period of postoperative observation is short and monitoring is not as intensive, ambulatory surgery is only suitable for low-risk procedures such as breast cancer surgery and in patients without serious comorbidities, where the likelihood of major perioperative events is low. Optimal management of pain, nausea, and vomiting is essential to ensure a quick recovery and return to normal function. Regional anesthesia such as the thoracic paravertebral block has been employed to improve pain control during the surgery and in the immediate postoperative period. The block provides excellent pain relief and reduces the need for opiates, which also consequently reduces the incidence of nausea and vomiting. The increasing popularity of total intravenous anesthesia with propofol has also helped reduce the incidence of nausea and vomiting in the postoperative period. Ambulatory surgery can be safely carried out in centers where there is a well-designed workflow to ensure proper patient selection, counseling, and education, and where patients and caregivers have easy access to

    2012-01-01

    Neoadjuvant chemoradiotherapy (NACRT) is an accepted standard treatment for low rectal advanced cancer to improve the local control in western countries. Recently laparoscopy has been recognized as an excellent tool from a view point of its magnification. Therefore, we have performed many laparoscopic surgeries for locally advanced rectal cancer after NACRT, We evaluated our results in this study. We studied 100 patients underwent surgery for locally advanced low rectal cancer after NACRT. Rate of sphincter preserving surgery was 74%. Rate of laparoscopic surgery was 95%. Positive distal resection margins were not identified in all patients. Positive circumferencial resection margins were identified in only two patients. The pathological complete response rate was 15%. The rate of postoperative complications was 15%. Complications were as follows: wound infection (9%), pelvic abscess (2%), ileus (2%) and others (2%), however without mortality. Anastomotic leakage was not observed in all cases, even though we routinely created diverting stoma. Laparoscopic surgery for low rectal cancer after NACRT is considered to be a safe and feasible procedure. (author)

  20. Reg proteins and their roles in inflammation and cancer of the human digestive system.

    Science.gov (United States)

    Zhao, Jie; Wang, Jingyu; Wang, Hao; Lai, Maode

    2013-01-01

    The regenerating gene (Reg) family is a group of small molecules that includes four members found in various species, although only three are found in human tissues. Their expression is stimulated by certain growth factors or cytokines. The Reg family plays different roles in proliferation, migration, and anti-apoptosis through activating different signaling pathways. Their dysexpression is closely associated with a number of human conditions and diseases such as inflammation and cancer, especially in the human digestive system. Clinically, upregulation of Reg proteins is usually demonstrated in histological sections and sera from cancer patients. Therefore, Reg proteins can predict the progression and prognosis of cancers, especially those of the digestive tract, and can also act as diagnostic markers and therapeutic targets.

    Cancer is a complex polygenic and multifactorial disease, resulting from successive dynamic changes in the genome of somatic cells and from the accumulation of molecular alterations in both tumour cells and host cells. For the majority of cancers, including many malignancies of the gastrointestinal tract, our current means of diagnosis and treatment of the tumors are grossly insufficient. In recent years the development of several gene expression profiling methods such as comparative genomic hybridization (CGH), differential display, serial analysis of gene expression (SAGE) and DNA arrays, together with the sequencing of the human genome, has provided an opportunity to monitor and investigate the complete cascade of molecular events leading to tumor development and progression. Given the central role played by surgeons in the current management of patients with solid cancers, it is of paramount importance for them to know the principles characterizing this laboratory tools to critically assess the results originating from this biotechnology. We describe in this article the scientific partnership between Fundeni Clinical Institute Bucharest, Romania and RNtech Company, Paris, France for the development of a center of biological resources (Biobank) as well as the standardized protocol of working with the biological samples, the ongoing projects and the future perspectives.

    2008-09-01

    We hypothesized that laparoscopic adjustable gastric banding (LAGB) reduces weight and modulates ghrelin production, but largely spares gastrointestinal endocrine function. To examine this hypothesis, we determined plasma concentrations of appetite-control, insulinotropic, and digestive hormones in relation to LAGB. Twenty-four patients undergoing LAGB were prospectively enrolled. Body mass index (BMI) was measured and blood samples obtained at baseline and 6 and 12 months post-surgery. Plasma concentrations of leptin, acylated and total ghrelin, pancreatic polypeptide (PP), insulin, glucose-dependent insulinotropic peptide (GIP), active glucagon-like peptide-1 (GLP-1), gastrin, and pepsinogens I and II were measured using enzyme-linked immunoassays. Median percent excess weight loss (%EWL) over 12 months was 45.7% with median BMI decreasing from 43.2 at baseline to 33.8 at 12 months post-surgery (p 0.05). Pepsinogen II levels were significantly lower 6 months after LAGB but returned to baseline levels by 12 months. LAGB yielded substantial %EWL and a proportional decrease in plasma leptin. Our results support the hypothesis that LAGB works in part by suppressing the rise in ghrelin that normally accompanies weight loss. Unchanged concentrations of insulinotropic and digestive hormones suggest that gastrointestinal endocrine function is largely maintained in the long term.

    Radioimmunoscintigraphic applications of monoclonal antibodies (Mabs) for noninvasive detection and visualization of target tumors have grown immensely, and it suggests that Mabs can reach specifically to the targeted tumors in the human body. Radionuclides, cytotoxic drugs and anti-cancer drugs can be coupled to these specific MAbs to detect the extent of disease and/or to treat the tumors. Many of such immunoconjugates were studied for targeting therapy for cancer in animal experiments and some of them have applied to human. In this paper, we described the existing status of application of Mabs for diagnosis and immunotargeting therapy of digestive cancers. (author)

    Central venous access port-related bloodstream infection (CVAP-BSI) is associated with morbidity and mortality in patients with cancer. This study examined the incidence rates and risk factors for CVAP-BSI in adult patients with digestive cancer. This prospective observational cohort study was performed from 2007 to 2011 in 2 oncology units of a university hospital. Incidence rate was expressed as number of CVAP-BSI per 1,000 catheter-days. A Cox regression model was used to identify risk factors for CVAP-BSI. A total of 315 patients were included. CVAP-BSI occurred in 41 patients (13.0%). The overall incidence rate was 0.76/1,000 catheter-days. The rate was higher in patients with esophageal cancer (1.28. P = .05) and pancreatic cancer (1.24; P = .007). Risk factors independently associated with CVAP-BSI were World Health Organization performance status between 2 and 4, catheter utilization-days in the previous month, pancreatic cancer, and parenteral nutrition. Coagulase-negative Staphylococci and enterobacteria were the main microorganisms isolated. In adult patients with digestive cancer, pancreatic cancer, cumulative catheter utilization-days, World Health Organization performance status, and parenteral nutrition were identified as independent risk factors for CVAP-BSI. Patients with any of these risk factors could be candidates for preventive strategies. Copyright © 2012 Association for Professionals in Infection Control and Epidemiology, Inc.

    The palliative care team (PCT), nutrition support team (NST), and department of nutrition in our hospital developed a special soup service for patients with terminal cancer. We evaluated the usefulness of this soup service for improving the mood in patients with advanced digestive cancer with severe anorexia. We retrospectively reviewed the clinical data of 18 patients with advanced cancer originating in digestive organs who received soup service at our institution between 2015 and 2016. Members of the PCT, NST, and a licensed cook visited the bedside of each patient and served them a cup of soup twice a week. Fifteen patients (83%) were able to taste the soup with no adverse events, and 11 (73%) of them enjoyed the taste of the soup. In the five patients who died in our hospital during the service, the time between their last soup intake and death ranged from two to seven days (median three days). Even terminally ill patients suffering from advanced digestive cancer with severe anorexia were able to enjoy the taste of the soup served to them. The establishment of special meal service, such as this soup service, may not only relieve their stress but also support the strength of living and help improve their spiritual quality of life.

    Cancer stem cells (CSCs) constitute a small proportion of the cancer cells that have self-renewal capacity and tumor-initiating ability. They have been identified in a variety of tumors, including tumors of the digestive system. CSCs exhibit some unique characteristics, which are responsible for cancer metastasis and recurrence. Consequently, the development of effective therapeutic strategies against CSCs plays a key role in increasing the efficacy of cancer therapy. Several potential approaches to target CSCs of the digestive system have been explored, including targeting CSC surface markers and signaling pathways, inducing the differentiation of CSCs, altering the tumor microenvironment or niche, and inhibiting ATP-driven efflux transporters. However, conventional therapies may not successfully eradicate CSCs owing to various problems, including poor solubility, stability, rapid clearance, poor cellular uptake, and unacceptable cytotoxicity. Nanomedicine strategies, which include drug, gene, targeted, and combinational delivery, could solve these problems and significantly improve the therapeutic index. This review briefly summarizes the ongoing development of strategies and nanomedicine-based therapies against CSCs of the digestive system.

  15. Common Beans and Their Non-Digestible Fraction: Cancer Inhibitory Activity—An Overview

    Rocio Campos-Vega

    2013-08-01

    Full Text Available The US Department of Agriculture’s MyPyramid guidelines introduced a near doubling of the dietary recommendations for vegetables including dry beans—an important food staple in many traditional diets that can improve public health and nutrition. Populations with high legume (peas, beans, lentils consumption have a low risk of cancer and chronic degenerative diseases. Common beans (Phaseolus vulgaris L. are known as a rich, reliable source of non-digested compounds like fiber, phenolics, peptides and phytochemicals that are associated with health benefits. Emerging evidence indicates that common bean consumption is associated with reduced cancer risk in human populations, inhibiting carcinogenesis in animal models and inducing cell cycle arrest and apoptosis in cell cultures. Fiber may reduce the risk of premature death from all causes, whereas the whole non-digestible fraction from common beans exhibits anti-proliferative activity and induces apoptosis in vitro and in vivo colon cancer. The mechanisms responsible for this apparently protective role may include gene-nutrient interactions and modulation of proteins’ expression. This review investigates the potential health benefits and bioactivity of beans on tumor inhibition, highlighting studies involving functional compounds, mainly non-digestible fractions that modulate genes and proteins, thereby, unraveling their preventive role against the development of cancer.

    Full Text Available Abstract Background Obesity has long been associated with postmenopausal breast cancer risk and more recently with premenopausal breast cancer risk. We previously observed that nipple aspirate fluid (n levels of prostate specific antigen (PSA were associated with obesity. Serum (s levels of adiponectin are lower in women with higher body mass index (BMI and with breast cancer. We conducted a prospective study of obese women who underwent gastric bypass surgery to determine: 1 change in n- and s-adiponectin and nPSA after surgery and 2 if biomarker change is related to change in BMI. Samples (30-s, 28-n and BMI were obtained from women 0, 3, 6 and 12 months after surgery. Findings There was a significant increase after surgery in pre- but not postmenopausal women at all time points in s-adiponectin and at 3 and 6 months in n-adiponectin. Low n-PSA and high s-adiponectin values were highly correlated with decrease in BMI from baseline. Conclusions Adiponectin increases locally in the breast and systemically in premenopausal women after gastric bypass. s-adiponectin in pre- and nPSA in postmenopausal women correlated with greater weight loss. This study provides preliminary evidence for biologic markers to predict weight loss after gastric bypass surgery.

    Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

    Several studies have reported an association between the A23G polymorphism (rs 1800975) in the xeroderma pigmentosum group A (XPA) gene and risk of digestive system cancers. However, the results are inconsistent. In this study, we performed a meta-analysis to assess the association between XPA A23G polymorphism and the risk of digestive system cancers. Relevant studies were identified using the PubMed, Web of Science, China National Knowledge Infrastructure, WanFang, and VIP databases up to August 30, 2014. The pooled odds ratio (OR) with a 95% confidence interval (CI) was calculated using the fixed or random effects model. A total of 18 case-control studies from 16 publications with 4,170 patients and 6,929 controls were included. Overall, no significant association was found between XPA A23G polymorphism and the risk of digestive system cancers (dominant model: GA + AA versus GG, OR 0.89, 95% CI 0.74-1.08; recessive model: AA versus GA + GG, OR 0.94, 95% CI 0.74-1.20; GA versus GG, OR 0.89, 95% CI 0.77-1.03; and AA versus GG, OR 0.87, 95% CI 0.64-1.19). When the analysis was stratified by ethnicity, similar results were observed among Asians and Caucasians in all genetic models. In stratified analysis based on tumor type, we also failed to detect any association between XPA A23G polymorphism and the risk of esophageal, gastric, or colorectal cancers. This meta-analysis indicates that the XPA A23G polymorphism is not associated with a risk of digestive system cancers.

    To evaluate the frequency of short-term pulmonary complications in the patients undergoing various head and neck cancer surgeries in our setup and to assess possible risk factors responsible for these complications. Seventy patients of age group 20 to 80 years, regardless of gender, treated surgically for head and neck cancers were enrolled. Main outcome measures included development of pulmonary complications following 15 days of oncological surgery. The complications studied were pneumothorax, bronchopneumonia, atelectasis, pulmonary embolism and cardiopulmonary arrest. A total of 24.28% patients suffered from postoperative pulmonary complications; 17.14% developed bronchopneumonia, 5.71% pulmonary embolism, and 1.42% went into cardiopulmonary arrest, none developed pneumothorax or pulmonary atelectasis. A significant correlation of postoperative bronchopneumonia was seen with heavy smoking and assisted ventilation. Pulmonary embolism was associated with extended assisted ventilation and prolonged surgery. Cardiopulmonary arrest was associated with comorbidity and assisted ventilation after surgery. The frequency of bronchopneumonia supersedes all of the postoperative pulmonary complications in head and neck oncological surgery. Patients at risk of developing postoperative complications are heavy smokers, diabetics, those undergoing prolonged surgery, tracheostomy, and extended assisted ventilation. (author)

    To maximize tumor excision and minimize collateral damage is the primary goal of cancer surgery. Emerging molecular imaging techniques have to “image-guided surgery” developing into “molecular imaging-guided surgery”, which is termed “targeted surgery” in this review. Consequently, the precision of surgery can be advanced from tissue-scale to molecule-scale, enabling “targeted surgery” to be a component of “targeted therapy”. Evidence from numerous experimental and clinical studies has demonstrated significant benefits of fluorescent imaging in targeted surgery with preoperative molecular diagnostic screening. Fluorescent imaging can help to improve intraoperative staging and enable more radical cytoreduction, detect obscure tumor lesions in special organs, highlight tumor margins, better map lymph node metastases, and identify important normal structures intraoperatively. Though limited tissue penetration of fluorescent imaging and tumor heterogeneity are two major hurdles for current targeted surgery, multimodality imaging and multiplex imaging may provide potential solutions to overcome these issues, respectively. Moreover, though many fluorescent imaging techniques and probes have been investigated, targeted surgery remains at a proof-of-principle stage. The impact of fluorescent imaging on cancer surgery will likely be realized through persistent interdisciplinary amalgamation of research in diverse fields. PMID:25064553

    Pancreatic cancer surgery represents a challenge for surgeons due to its technical complexity, the potential complications that may appear, and ultimately because of its poor survival. The aim of this article is to summarize the scientific evidence regarding the surgical treatment of pancreatic cancer in order to help surgeons in the decision making process in the management of these patients .Here we will review such fundamental issues as the need for a biopsy before surgery, the type of pancreatic anastomosis leading to better results, and the need for placement of drains after pancreatic surgery will be discussed.

  4. Excisional surgery for cancer cure: therapy at a cost.

    LENUS (Irish Health Repository)

    Coffey, J C

    2012-02-03

    Excisional surgery is one of the primary treatment modalities for cancer. Minimal residual disease (MRD) is the occult neoplastic disease that remains in situ after curative surgery. There is increasing evidence that tumour removal alters the growth of MRD, leading to perioperative tumour growth. Because neoplasia is a systemic disease, this phenomenon may be relevant to all patients undergoing surgery for cancer. In this review we discuss the published work that addresses the effects of tumour removal on subsequent tumour growth and the mechanisms by which tumour excision may alter residual tumour growth. In addition, we describe therapeutic approaches that may protect patients against any oncologically adverse effects of tumour removal. On the basis of the evidence presented, we propose a novel therapeutic paradigm; that the postoperative period represents a window of opportunity during which the patient may be further protected against the oncological effects of tumour removal.

    Cancer cachexia is an important measure of physiologic reserve associated with worse survival and represents an actionable factor for the cancer population. However, the incidence of cachexia in surgical cancer patients and its impact on postoperative outcomes are currently unknown. A prospective cohort study enrolling patients having elective cancer surgery (2012-2014) at a Veterans Affairs tertiary referral center. Preoperative cancer cachexia (weight loss ≥5% over 6-mo period before surgery) was the predictor of interest. The primary outcome was 60-d postoperative complications (VA Surgical Quality Improvement Program). Patients were grouped by body mass index (BMI) category (cachexia and BMI was tested for the primary outcome. Multivariate logistic regression was used to examine the association between preoperative cachexia and postoperative complications. Of 253 patients, 16.6% had preoperative cachexia, and 51.8% developed ≥ 1 postoperative complications. Complications were more common in cachectic patients (64.3% versus 49.3%, P = 0.07). This association varied by BMI category, and interaction analysis was significant for those with normal or underweight BMI (BMI cachexia was associated with higher odds of postoperative complications (odds ratios, 5.08 [95% confidence intervals, 1.18-21.88]; P = 0.029). Additional predictors of complications included major surgery (3.19 [1.24-8.21], P = 0.01), ostomy (4.43 [1.68-11.72], P = 0.003), and poor baseline performance status (2.31 [1.05-5.08], P = 0.03). Cancer cachexia is common in surgical patients, and is an important predictor of postoperative complications, though its effect varies by BMI. As a modifiable predictor of worse outcomes, future studies should examine the role of cachexia treatment before cancer surgery. Copyright © 2016 Elsevier Inc. All rights reserved.

    Psychological distress is common among patients with oesophageal cancer. However, little is known about the course and predictors of psychological distress among patients treated with curative intent. Therefore, the aim of this study was to explore the prevalence, course and predictors of anxiety and depression in patients operated for oesophageal cancer, from prior to surgery to 12 months post-operatively. A prospective cohort of patients with oesophageal cancer (n = 218) were recruited from one high-volume specialist oesophago-gastric treatment centre (St Thomas' Hospital, London, UK). Anxiety and depression were assessed prior to surgery, 6 and 12 months post-operatively. Mixed-effects modelling was performed to investigate changes over time and to estimate the association between clinical and socio-demographic predictor variables and anxiety and depression symptoms. The proportion of patients with anxiety was 33% prior to surgery, 28% at 6 months, and 37% at 12 months. Prior to surgery, 20% reported depression, 27% at 6 months, and 32% at 12-month follow-up. Anxiety symptoms remained stable over time whereas depression symptoms appeared to increase from pre-surgery to 6 months, levelling off between 6 and 12 months. Younger age, female sex, living alone and more severe self-reported dysphagia (i.e., difficulty swallowing) predicted higher anxiety symptoms. In-hospital complications, greater limitations in activity status and more severe self-reported dysphagia were predictive of higher depression. Many patients report psychological distress during the first year following oesophageal cancer surgery. Whether improving the experience of swallowing difficulties may also reduce distress among these patients warrants further study.

    Comorbidities have considerable effects on survival outcomes. The primary objective of this retrospective study was to examine the association between age-adjusted Charlson comorbidity index (ACCI) score and postoperative in-hospital mortality in patients with digestive system cancer who have undergone surgical resection of their cancers. Using electronic hospitalization summary reports, we identified 315,464 patients who had undergone surgery for digestive system cancer in top-rank (Grade 3A) hospitals in China between 2013 and 2015. The Cox proportional hazard regression model was applied to evaluate the effect of ACCI score on postoperative mortality, with adjustments for sex, type of resection, anesthesia methods, and caseload of each healthcare institution. The postoperative in-hospital mortality rate in the study cohort was 1.2% (3,631/315,464). ACCI score had a positive graded association with the risk of postoperative in-hospital mortality for all cancer subtypes. The adjusted HRs for postoperative in-hospital mortality scores ≥ 6 for esophagus, stomach, colorectum, pancreas, and liver and gallbladder cancer were 2.05 (95% CI: 1.45-2.92), 2.00 (95% CI: 1.60-2.49), 2.54 (95% CI: 2.02-3.21), 2.58 (95% CI: 1.68-3.97), and 4.57 (95% CI: 3.37-6.20), respectively, compared to scores of 0-1. These findings suggested that a high ACCI score is an independent predictor of postoperative in-hospital mortality in Chinese patients with digestive system cancer who have undergone surgical resection.

In most cases with spreading the tumor to the tracheal rings performing of organ-preserving operations (from “window-like” tracheal resections to circular tracheal resection with intertracheal anastomosis is possible. Choosing of type of operation to be performed depends on localisation and spread of tumor invasion of trachea, pharynx and esophagus. Using of combined operations in patients with locally-spread thyroid cancer allows to achieve long and stable remission in most of the cases.

    We proposed transoral videolaryngoscopic surgery (TOVS) as a laryngeal preservation strategy for laryngopharyngeal cancer. By using a distending laryngoscope and rigid laryngeal endoscope, a large field of view and working space could be obtained which enabled us to resect tumors in en-bloc fashion. The indications for this surgery are oro-hypopharyngeal and supraglottic cancer in superficial, T1, T2 and selected T3 categories. TOVS can also be used for selected cases with recurrent tumor after radiation therapy. For resectable nodal metastasis, neck dissection can be performed simultaneously or 1-2 weeks later. In cases with more than a 1-year observation period (n=42), 5-year crude survival, disease-specific survival, and laryngeal preservation rate were 74%, 85% and 89%, respectively. A second advantage of TOVS is thorough evaluation of primary cancer lesion. Evaluation of tumor invasion depth is a promising way for optimizing the indication for neck dissection for clinically node negative cases. (author)

    FDOPA-PET has been proposed for a decade in oncology, in particular in endocrine tumours. To the best of our knowledge, only one impact rate has been reported: 31% in 17 patients with digestive carcinoid tumours. We did a questionnaire survey to evaluate this impact reported by the referring clinician in 87 patients who had FDOPA PET due to digestive carcinoid tumour or another type of digestive endocrine tumour or a medullary thyroid cancer or a pheochromocytoma. The response rate to the survey was 87%. The overall impact of FDOPA PET on patient's management was 36%. Its value was greater for digestive carcinoid tumour and for medullary thyroid cancer; the number of patients with pheochromocytoma is still limited. In the other digestive endocrine tumours, a change in patient management was less frequent and FDOPA PET should be performed when the other examinations are inconclusive. (author)

    Full Text Available Introduction. The patient’s age is one of the major risk factors of death from colorectal cancer. The role of laparo- scopic radical surgeries in the treatment of colorectal cancer in elderly patients is being studied. The purpose of the study was to evaluate the experience of surgical treatment for elderly patients with colorectal cancer. material and methods. The treatment outcomes of 106 colorectal cancer patients aged 75 years or over, who underwent surgery between 2013 and 2015 were presented. Out of them, 66 patients underwent laparatomy and 40 patients underwent laparoscopy. Patients were matched for ASA and CR-PОSSUM scales, age-and body mass index, dis- ease stage and type of surgery. Results. The mean duration of surgery was significantly less for laparoscopy than for laparotomy (127 min versus 146 min. Intraoperative blood loss was higher in patients treated by laparotomy than by laparoscopy (167 ml versus 109 ml, but the differences were insignificant (р=0.36. No differences in lymphodissection quality and adequate resection volume between the groups were found. The average hospital stay was not significantly shorter in the laparoscopic group (р=0.43. Complications occurred with equal frequency in both groups (13.6 % compared to 15.0 %. The median follow-up time was 16 months (range, 6-30 months. The number of patients died during a long-term follow-up was 2 times higher after laparotomic surgery than after laparoscopic surgery, however, the difference was not statistically significant. Conclusion. Postoperative compli- cations in elderly patients with colorectal cancer did not exceed the average rates and did not depend on the age. Both groups were matched for the intraoperative bleeding volume and quality of lymphodenectomy. Significantly shorter duration of laparoscopic surgery was explained by the faster surgical access however, it showed no benefit in reducing the average length of hospital stay and decreasing the number of

    Loss of Raf kinase inhibitor protein (RKIP) may contribute to metastasis in a variety of human cancers. Many studies have evaluated whether loss of RKIP expression is a prognostic factor for survival in cancers of the digestive system, however, its predictive value remains controversial. Thus, we performed a meta-analysis to obtain a more comprehensive estimate of the prognostic value of RKIP expression in digestive system cancers. Studies were identified by searching multiple electronic databases through December 12, 2013, and by reviewing reference lists of obtained articles. Studies reported hazard ratios (HRs) with 95% confidence intervals (CIs) for the association between RKIP and overall survival (OS) and disease-free survival (DFS) in cancers of the digestive system were eligible, including esophageal cancer, gastric cancer, colorectal cancer and pancreatic cancer. Nineteen studies involving approximately 3700 participants were included in the final analysis. The pooled results suggested that loss of RKIP expression was associated with unfavorable OS (HR 0.55, 95% CI 0.46-0.65) and DFS (HR 0.46, 95% CI 0.30-0.62) among patients with digestive system cancers, whereas the difference was not statistically significant in pancreatic cancer specifically (OS, HR 0.76; 95% CI 0.51-1.01; DFS, HR 0.71; 95% CI 0.28-1.13). Loss of RKIP expression might be an independent indicator of poor prognosis in patients with digestive tract cancers, which includes esophageal cancer, gastric cancer and colorectal cancer. More studies are needed to further clarify the prognostic value of RKIP in pancreatic cancer. Future studies, preferably large prospective studies utilizing formal marker assessment processes, are needed to establish the prognostic value of RKIP before these results can be clinically applied.

    Regionalization of complex surgeries has increased patient travel distances possibly leaving a substantial burden on those at risk for poorer surgical outcomes. To date, little is known about travel patterns of cancer surgery patients in regionalized settings. To inform this issue, we sought to assess travel patterns of those undergoing a major cancer surgery within a regionalized system. We identified 4733 patients who underwent lung, esophageal, gastric, liver, pancreatic, and colorectal resections from 2002-2014 within a multihospital system in the Mid-Atlantic region of the United States. Patient age, race and/or ethnicity, and insurance status were extracted from electronic health records. We used Geographical Information System capabilities in R software to estimate travel distance and map patient addresses based on cancer surgery type and these characteristics. We used visual inspection, analysis of variance, and interaction analyses to assess the distribution of travel distances between patient populations. A total of 48.2% of patients were non-white, 49.9% were aged >65 y, and 54.9% had private insurance. Increased travel distance was associated with decreasing age and those undergoing pancreatic and esophageal resections. Also, black patients tend to travel shorter distances than other racial and/or ethnic groups. These maps offer a preliminary understanding into variations of geospatial travel patterns among patients receiving major cancer surgery in a Mid-Atlantic regionalized setting. Future research should focus on the impact of regionalization on timely delivery of surgical care and other quality metrics. Copyright © 2015 Elsevier Inc. All rights reserved.

    The high incidence rate of multiple carcinomas in the upper digestive tract is often explained in terms of involvement of the same underlying risk factors. It has been reported that the oral bacterium Streptococcus anginosus is associated with esophageal, gastric, and pharyngeal cancers. We previously reported occurrence of Porphyromonas gingivalis (P. gingivalis) DNA in esophagus cancer. In this study, the presence of P. gingivalis in specimens of various types of cancer from the upper digestive tract was investigated. Here we report that P. gingivalis was preferentially and frequently present in specimens of esophageal cancer as well as in those from dysplasia of the esophagus but rarely in matched noncancerous portions and are quite low or absent in cancers from the cardia or stomach. Therefore, it led us to propose that, the microorganism does not survive in conditions of high acidity. We then investigate the pH dependence of survival of P. gingivalis as well as the acid tolerance of it. We found that, exposure to acidic buffers of a wide range of pH values led to a decline in colony forming units of P. gingivalis, thus, providing a possible explanation for variations in frequencies of P. gingivalis infection in this study.

    Laparoscopic surgery for colorectal cancer is currently accepted and widespread worldwide. However, according tol the surgical experience on this approach, surgical and short-term oncologic results may vary. Studies comparing laparoscopic vs. open surgery in our population are scarce. To determine the superiority of the laparoscopic vs. open technique for colorectal cancer surgery. This retrospective and comparative study collected data from patients operated on for colorectal cancer between 1999 and 2011 at the Angeles Lomas Hospital, Mexico. A total of 82 patients were included in this study; 47 were operated through an open approach and 35 laparoscopically. Mean operative time was significantly lower in the open approach group (p= 0.008). There were no significant difference between both techniques for intraoperative bleeding (p= 0.3980), number of lymph nodes (p= 0.27), time to initiate oral feeding (p= 0.31), hospital stay (p= 0.12), and postoperative pain (p= 0.19). Procedure-related complications rate and type were not significantly different in both groups (p= 0.44). Patients operated laparoscopically required significantly less analgesic drugs (p= 0.04) and less need for epidural postoperative analgesia (p= 0.01). Laparoscopic approach is as safe as the traditional open approach for colorectal cancer. Early oncological and surgical results confirm its suitability according to this indication.

    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.

    Morbid obesity is a known risk factor for the development of endometrial cancer. Several studies have demonstrated the overall feasibility of robotic-assisted surgical staging for endometrial cancer as well as the benefits of robotics compared with laparotomy. However, there have been few reports that have evaluated robotic surgery for endometrial cancer in the supermorbidly obese population (body mass index [BMI], ≥50 kg/m(2)). We sought to evaluate safety, feasibility, and outcomes for supermorbidly obese patients who undergo robotic surgery for endometrial cancer, compared with patients with lower body mass indices. We performed a retrospective chart review of 168 patients with suspected early-stage endometrial adenocarcinoma who underwent robotic surgery for the management of their disease. Analysis of variance and univariate logistic regression were used to compare patient characteristics and surgical variables across all body weights. Cox proportional hazard regression was used to determine the impact of body weight on recurrence-free and overall survival. The mean BMI of our cohort was 40.9 kg/m(2). Median follow up was 31 months. Fifty-six patients, 30% of which had grade 2 or 3 tumors, were supermorbidly obese with a BMI of ≥50 kg/m(2) (mean, 56.3 kg/m(2)). A comparison between the supermorbidly obese and lower-weight patients demonstrated no differences in terms of length of hospital stay, blood loss, complication rates, numbers of pelvic and paraaortic lymph nodes retrieved, or recurrence and survival. There was a correlation between BMI and conversion to an open procedure, in which the odds of conversion increased with increasing BMI (P = .02). Offering robotic surgery to supermorbidly obese patients with endometrial cancer is a safe and feasible surgical management option. When compared with patients with a lower BMI, the supermorbidly obese patient had a similar outcome, length of hospital stay, blood loss, complications, and numbers of lymph

    PD-L1 has been reported to be expressed in diverse human malignancies. However, the prognostic value of PD-L1 in digestive system cancers remains inconclusive. Therefore, we conducted this meta-analysis to evaluate the prognostic impact of PD-L1 expression in digestive system cancers. We searched the PubMed, Embase, and the Chinese National Knowledge Infrastructure for publications concerning PD-L1 expression in digestive system cancers. Correlations of PD-L1 expression level with overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) were analyzed. Finally, 32 studies with 7,308 patients were included. Our results show that PD-L1 expression was significantly associated with poorer OS (hazard ratio [HR] =1.44, 95% confidence interval [CI] =1.18-1.76, P digestive system cancers, especially in gastric cancer and pancreatic cancer. In addition, PD-L1 may act as a new parameter for predicting poor prognosis and a promising target for anticancer therapy in digestive system cancers.

    Since the emergence of minimally invasive technology twenty years ago, as a surgical concept and surgical technique for colorectal cancer surgery, its obvious advantages have been recognized. Laparoscopic technology, as one of the most important technology platform, has got a lot of evidence-based support for the oncological safety and effectiveness in colorectal cancer surgery Laparoscopic technique has advantages in terms of identification of anatomic plane and autonomic nerve, protection of pelvic structure, and fine dissection of vessels. But because of the limitation of laparoscopic technology there are still some deficiencies and shortcomings, including lack of touch and lack of stereo vision problems, in addition to the low rectal cancer, especially male, obese, narrow pelvis, larger tumors, it is difficult to get better view and manipulating triangle in laparoscopy. However, the emergence of a series of new minimally invasive technology platform is to make up for the defects and deficiencies. The robotic surgical system possesses advantages, such as stereo vision, higher magnification, manipulator wrist with high freedom degree, filtering of tremor and higher stability, but still has disadvantages, such as lack of haptic feedback, longer operation time, high operation cost and expensive price. 3D system of laparoscopic surgery has similar visual experience and feelings as robotic surgery in the 3D view, the same operating skills as 2D laparoscopy and a short learning curve. The price of 3D laparoscopy is also moderate, which makes the 3D laparoscopy more popular in China. Transanal total mesorectal excision (taTME) by changing the traditional laparoscopic pelvic surgery approach, may have certain advantages for male cases with narrow pelvic and patients with large tumor, and it is in accordance with the technical concept of natural orifice, with less minimally invasive and better cosmetics, which can be regarded as a supplemental technique of the

    To evaluate the association between the tumour necrosis factor alpha-308 (TNF-α-308) gene polymorphism and the risk of digestive system cancers. All eligible case-control studies published up to December 2012 were identified by searching PubMed, Web of Science, Embase and China National Knowledge Internet without language restrictions. The risk of digestive system cancers associated with the TNF-α-308 polymorphism was estimated for each study using odds ratio (OR) together with its 95%CI, respectively. Cochrane Collaboration RevMan 5.1 was used to perform the analysis. A χ²-test-based Q statistic test and an I² test were performed to assess the between-study heterogeneity. When the Q test was significant (P 50%, the random effects model was used, otherwise the fixed effects model was used. Fifty-eight studies from fifty-five publications with a total of 9986 cancer patients and 15511 healthy controls were included. Overall, a significant association was found between the TNF-α-308 polymorphism and the risk of digestive system cancers [dominant model: OR = 1.23, 95%CI: 1.09-1.39, (G/A) vs (G/G): OR = 1.15, 95%CI: 1.02-1.28, (A/A) vs (G/G): OR = 1.44, 95%CI: 1.19-1.73, recessive model: OR = 1.38, 95%CI: 1.15-1.66]. Furthermore, when the analysis was stratified by ethnicity, similar results were observed in both the Asian and Caucasian populations, except for the dominant model and heterozygote comparisons in the Asian population [dominant model: OR = 1.24, 95%CI: 0.99-1.56, (G/A) vs (G/G): OR = 1.09, 95%CI: 0.96-1.24]. When the cancer type subgroups were examined, similar results were detected in gastric and hepatocellular carcinomas; however, no significant association was observed among other digestive system cancers. The TNF-α-308 gene polymorphism may be significantly associated with the risk of gastric and hepatocellular carcinomas, but not colorectal, pancreatic, or oesophageal cancer, in the Asian population.

    Full Text Available The treatment of rectal cancer has been improved a great deal within the last 20 years. Major progress has been made in the preoperative evaluation by introducing MRI- imaging as a basis for the further management. Neoadjuvant radiochemotherapy has been shown to be effective in downstaging of advanced tumours. The surgical technique has been improved in many respects.- Total mesorectal excision has reduced local recurrences, sphincter saving techniques such as low anterior resection and intersphincteric resection reduced the need for a permanent stoma to 10%-20%. Recently the introduction of minimal invasive techniques and the application of robotic systems have reduced the surgical trauma.

    The laparoscopic technique was introduced in gastrointestinal surgery in the mid 1980s. Since then, the development of this technique has been extraordinary. Triggered by technical innovations (stapling devices or coagulation/dissecting devices), nowadays any type of gastrointestinal resection has been successfully performed laparoscopically and can be performed laparoscopically dependent on the patient's condition. This summary gives an overview over 30 years of laparoscopic surgery with focus on today's indications and evidence. Main indications remain the more common procedures, e.g., appendectomy, cholecystectomy, bariatric procedures or colorectal resections. For all these indications, the laparoscopic approach has become the gold standard with less perioperative morbidity. Regarding oncological outcome there have been several high-quality randomized controlled trials which demonstrated equivalency between laparoscopic and open colorectal resections. Less common procedures like esophagectomy, oncological gastrectomy, liver and pancreatic resections can be performed successfully as well by an experienced surgeon. However, the evidence for these special indications is poor and a general recommendation cannot be given. In conclusion, laparoscopic surgery has revolutionized the field of gastrointestinal surgery by reducing perioperative morbidity without disregarding surgical principles especially in oncological surgery.

    Full Text Available Background: most studies that analyze the influence of structure factors on clinical outcomes are retrospective, based on clinical-administrative databases, and mainly focusing on surgical volume. Objective: to study variations in the process and outcomes of oncologic surgery for esophagus, stomach, pancreas, liver metastases and rectum cancers in Catalonia, as well as the factors associated with these variations. Patients and method: a retrospective (2002 and prospective (2003-05 multicenter cohort study. Data forms were designed to collect patient, process, and care outcome characteristics before surgery, at hospital discharge, and at 3 and 6 months after discharge. Main outcome measures were hospital and follow-up mortality, complications, re-interventions, and relapse rates. Results: 49 hospitals (80% participated in the retrospective phase, 44 of which (90% also participated in the prospective phase: 3,038 patients (98% were included. No differences were observed in the profile of operated patients according to hospital level of complexity, but clinical-pathological staging and other functional status variables could not be assessed because of over 20% of missing values. There was significant variability in the volume of interventions as well as in certain aspects of the healthcare process depending on type of cancer and center complexity. High rates of esophageal cancer mortality (18.2% at discharge, 27.3% at 6 months and of complications and re-interventions for all cancers assessed, especially rectal cancer (18.4% re-interventions at 6 months, were identified. Conclusions: the study of the variability identified will require adequate risk-adjustment and should take into account different structure factors. It is necessary that information included in medical records be improved.Antecedentes: la mayoría de estudios que analizan la influencia de factores de estructura sobre los resultados son retrospectivos, realizados con bases de datos

    Although radical nephrectomy is still practiced in many patients with large renal tumors, oncology and nephrology arguments for kidney-sparing approach for small renal masses has taken over this first. Indeed, partial nephrectomy provides equivalent oncologic results while preserving renal function and thereby limit morbidity and cardiovascular mortality related to chronic kidney disease. In addition, patients who develop kidney cancer often have medical comorbidities that may affect renal function, such as diabetes and hypertension. Histological examination of renal tissue adjacent to the tumor showed significant pathological changes in the majority of patients. For elderly patients or patients with comorbidities, active surveillance allows kidney-sparing approach with extremely low rates of progression and metastasis of cancer disease. Despite these significant advances in understanding for the treatment of small renal masses, partial nephrectomy remains underused. Better management must take into account the preservation of renal function in order to increase overall survival. A strategy for the systematic evaluation of renal function in patients with CR, with multidisciplinary staff (nephrologist urologist and oncologist), is therefore highly desirable.

    In the preoperative evaluation for gastric cancer, high-resolution endoscopic technologies allow us to detect small accessory lesions. However, it is not known if the gastric remnant after partial gastrectomy for synchronous multiple gastric cancers has a greater risk for metachronous cancer. The purpose of this study was to determine the incidence of metachronous cancer in this patient subset compared with that after solitary cancer surgery. Data on a consecutive series of 1,281 patients gastrectomized for early gastric cancer from 1991 to 2007 were analyzed retrospectively. The 715 gastric remnants after distal gastrectomy were periodically surveyed by endoscopic examination in Shikoku Cancer Center. Among those surveyed cases, 642 patients were pathologically diagnosed with solitary lesion (SO group) and 73 patients with synchronous multiple lesions (MU group) at the time of the initial surgery. In the follow-up period, 15 patients in the SO group and 3 patients in the MU group were diagnosed as having metachronous cancer in the gastric remnant. The cumulative 4-year incidence rate was 1.9 % in the SO group and 5.5 % in the MU group. The difference did not reach the significant level by the log-rank test. The incidence of metachronous cancer is higher after multiple cancer surgery; however, the difference is not statistically significant.

    Little is known about how the structure of interdisciplinary groups of physicians affects the timeliness of breast cancer surgery their patients receive. We used social network methods to examine variation in surgical delay across physician peer groups and the association of this delay with group characteristics. We used linked Surveillance, Epidemiology, and End Results-Medicare data to construct physician peer groups based on shared breast cancer patients. We used hierarchical generalized linear models to examine the association of three group characteristics, patient racial composition, provider density (the ratio of potential vs. actual connections between physicians), and provider transitivity (clustering of providers within groups), with delayed surgery. The study sample included 8338 women with breast cancer in 157 physician peer groups. Surgical delay varied widely across physician peer groups (interquartile range 28.2-50.0%). For every 10% increase in the percentage of black patients in a peer group, there was a 41% increase in the odds of delayed surgery for women in that peer group regardless of a patient's own race [odds ratio (OR) 1.41, 95% confidence interval (CI) 1.15-1.73]. Women in physician peer groups with the highest provider density were less likely to receive delayed surgery than those in physician peer groups with the lowest provider density (OR 0.65, 95% CI 0.44-0.98). We did not find an association between provider transitivity and delayed surgery. The likelihood of surgical delay varied substantially across physician peer groups and was associated with provider density and patient racial composition.

    Features of ultrasound picture of morphologically verified recurrence of ovarian cancer in 21 patients are presented, who received combined treatment including cytoreductive surgery in the form of hysterectomy with oophorectomy, resection of the greater omentum and 6 courses of chemotherapy CAP for ovarian cancer stage III (FIGO). In all patients cytoreductive surgery was optimal--without residual tumor. Recurrence of the disease was detected in 12-48 months in 80.9% of the cases. Three variants of recurrence was revealed by ultrasonography: isolated peritoneal dissemination, in 14.2% of the cases, which was mainly detected during the first 12 months; single entities in the projection of the small pelvis (61.9%) and mixed form (local lesions of small pelvis and peritoneal dissemination) in 23.8% of the cases.

    The relationship between biliary tract inflammation (BTI) and digestive system cancers is unclear. This study aimed to evaluate the association between BTI and the risks of digestive system cancers.Using the Taiwan National Health Insurance claims data, information on a cohort of patients diagnosed with BTI (n = 4398) between 2000 and 2009 was collected. A comparison cohort of sex-, age-, and index year-matched persons without BTI (n = 17,592) was selected from the same database. The disease was defined by the ICD-9-CM. Both cohorts were followed until the end of 2010 and incidences of digestive system cancers were calculated.The results revealed an increase in adjusted hazard ratio (aHR) of biliary tract cancer (24.45; 95% confidence interval [CI]: 9.20-65.02), primary liver cancer (1.53; 95% CI: 1.07-2.18), and pancreatic cancer (3.10; 95% CI: 1.20-8.03) in patients with both gallbladder and BTI. The aHR of stomach cancer was also found to be increased (2.73; 95% CI: 1.28-5.81) in patients with gallbladder inflammation only. There were no differences in esophageal cancer (aHR: 0.82; 95% CI: 0.23-2.87) and colorectal cancer (aHR: 0.92; 95% CI: 0.59-1.45). The aHR for digestive system cancers increased by 3.66 times (95% CI: 2.50-5.35) and 12.20 times (95% CI: 8.66-17.17) in BTI visits frequency averaged 2 to 4 visits per year and frequency averaged ≥5 visits per year, respectively.Patients with BTI have significantly higher risk of digestive system cancers, particularly biliary tract, pancreatic, and primary liver cancers, compared with those who are without it.

    The incidence of pancreatic adenocarcinoma (PDAC) has steadily increased over the past several decades. The majority of PDAC patients will present with distant metastases, limiting surgical management in this population. Hepatectomy and pulmonary metastasectomy (PM) has been well established for colorectal cancer patients with isolated, resectable hepatic or pulmonary metastatic disease. Recent advancements in effective systemic therapy for PDAC have led to the selection of certain patients where metastectomy may be potentially indicated. However, the indication for resection of oligometastases in PDAC is not well defined. This review will discuss the current literature on the surgical management of metastatic disease for PDAC with a specific focus on surgical resection for isolated hepatic and pulmonary metastases.

    2016-01-04

    Neutrophil gelatinase-associated lipocalin, known also as 24p3 lipocalin, lipocalin-2 or uterocalin (in mouse), is a small secretory protein binding small molecular weight ligands which takes part in numerous processes including apoptosis induction in leukocytes, iron transport, smell, and prostaglandins and retinol transport [19]. It was discovered in activated neutrophils as a covalent peptide associated with human gelatinase neutrophils [7]. Neutrophil lipocalin is secreted physiologically in the digestive system, respiratory tract, renal tubular cells, liver or immunity system. Systematic (circulated in plasma) neutrophil gelatinase come from multiple sources; it may be synthesized in the liver, secreted from activated neutrophils or macrophages, or derive from atherosclerosis or inflammatory endothelial cells [17]. NGAL is stored secondarily in granulates with lactoferrin, calprotectin or MAC-1, which take part in neutrophils' action and migration [13,19]. NGAL participates in acute and chronic inflammation (production of NGAL is indicated by factors conducive to cancer progression) [13,21]. NGAL levels increase in inflammatory or endothelial damage. NGAL level is measured in blood or urine. It is known as a kidney failure factor [7,20]. NGAL is therefore one of the most promising new generation biomarkers in clinical nephrology [6]. The role of NGAL in digestive system neoplasms has not been explored in detail. However, overexpression of this marker was proved in neoplasms such as esophageal carcinoma, stomach cancer, pancreatic cancer or colon cancer, which may indicate an association between concentration and neoplasm [3].

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

    Data from in vitro and animal studies support a protective role for tea in the etiology of digestive system cancers; however, results from prospective cohort studies have been inconsistent. In addition, to our knowledge, no study has investigated the association of tea consumption with the incidence of all digestive system cancers in Chinese women. We investigated the association of regular tea intake (≥3 times/wk for >6 mo) with risk of digestive system cancers. We used the Shanghai Women's Health Study, a population-based prospective cohort study of middle-aged and older Chinese women who were recruited in 1996-2000. Adjusted HRs and associated 95% CIs were derived from Cox regression models. After a mean follow-up of 11 y, 1255 digestive system cancers occurred (stomach, esophagus, colorectal, liver, pancreas, and gallbladder/bile duct cancers) in 69,310 nonsmoking and non-alcohol-drinking women. In comparison with women who never drank tea, regular tea intake (mostly green tea) was associated with reduced risk of all digestive system cancers combined (HR: 0.86; 95% CI: 0.74, 0.98), and the reduction in risk increased as the amount and years of tea consumption increased (P-trend = 0.01 and P-trend digestive system cancers combined (HR: 0.79; 95% CI: 0.63, 0.99). The inverse association was found primarily for colorectal and stomach/esophageal cancers. In this large prospective cohort study, tea consumption was associated with reduced risk of colorectal and stomach/esophageal cancers in Chinese women.

Our surgical clinic treated 49 patients with colorectal cancer, of whom 28 (57.14% were men of mean age 62 years and 21 (42.86% were women of mean age 66 years.Methods: In 15 cases, the cancer was related to the rectum (30.61% and the remaining 34 cases (69.39% were related to the colon. We found synchronous cancer in two patients. One was found in the blank and the upper right while the second was found in the transverse and sigmoid colon. Six of our patients suffered from coexisting biliary lithiasis and underwent simultaneous cholecystectomy, and simultaneous bile duct exploration for common bile duct lithiasis was performed in one of these patients.Results: Twenty-eight of the patients with colon cancer were treated surgically on an emergency basis. There were two postoperative deaths due to septic shock and multiple organ failure. In total, we noted seven complications, all of which involved patients who had undergone emergency surgery. The length of hospital stay was 8–14 days. Four patients with stage IV disease died 2 years after surgery, and the remainder are still alive.Conclusion: We conclude that colon cancer still occurs after the sixth decade, with a male predominance, and is mainly located in the rectum and sigmoid colon. The high rate of ileus in our region indicates inadequate diagnostic access for the residents of our region.

  1. Interval debulking surgery in advanced epithelial ovarian cancer.

    Cytoreductive surgery and chemotherapy are the mainstay for the treatment of advanced epithelial ovarian cancer. In order to minimize the tumour burden before chemotherapy, cytoreductive surgery is usually performed first. The importance of the amount of residual disease as the main prognostic factor for patients suffering from advanced disease has been almost universally accepted even in the absence of prospective randomized trials addressing the benefit of cytoreductive surgery. In the last decade, the value of debulking surgery after induction chemotherapy - interval debulking surgery, IDS - has been widely debated, especially after the completion of a prospective randomized study from the EORTC addressing the introduction of a surgical procedure with debulking intent preceded and followed by cytoreductive chemotherapy. The rationale of such a strategy in the context of the primary treatment of advanced ovarian cancer lies in a higher cytoreductibility to the 'optimal' status forwarded, and possibly facilitated, by chemotherapy. The results demonstrated a prolongation of both progression-free survival and median survival in favour of patients randomized to IDS (5 and 6 months, respectively). Multivariate analysis revealed IDS to be an independent prognostic factor which reduced the risk of death by 33% at 3 years and by 48% in subsequent re-evaluation after more than 6 years of observation. Despite the above, results have been questioned by many, leading the GOG to perform a similar study which has been concluded very recently. Nevertheless, the main concern regarding the application of IDS in all instances relates to the morbidity of two major surgical procedures integrated within a short period during which cytotoxic chemotherapy is also administered. Neoadjuvant chemotherapy has been recently proposed to avoid a non-useful surgical procedure in patients considered 'optimally unresectable' after diagnosis of advanced ovarian cancer. Whether or not this newer

    Curative cancer operations lead to debility and loss of autonomy in a population vulnerable to suicide death. The extent to which operative intervention impacts suicide risk is not well studied. To examine the effects of morbidity of curative cancer surgeries and prognosis of disease on the risk of suicide in patients with solid tumors. Retrospective cohort study using Surveillance, Epidemiology, and End Results data from 2004 to 2011; multilevel systematic review. General US population. Participants were 482 781 patients diagnosed with malignant neoplasm between 2004 and 2011 who underwent curative cancer surgeries. Death by suicide or self-inflicted injury. Among 482 781 patients that underwent curative cancer surgery, 231 committed suicide (16.58/100 000 person-years [95% confidence interval, CI, 14.54-18.82]). Factors significantly associated with suicide risk included male sex (incidence rate [IR], 27.62; 95% CI, 23.82-31.86) and age >65 years (IR, 22.54; 95% CI, 18.84-26.76). When stratified by 30-day overall postoperative morbidity, a significantly higher incidence of suicide was found for high-morbidity surgeries (IR, 33.30; 95% CI, 26.50-41.33) vs moderate morbidity (IR, 24.27; 95% CI, 18.92-30.69) and low morbidity (IR, 9.81; 95% CI, 7.90-12.04). Unit increase in morbidity was significantly associated with death by suicide (odds ratio, 1.01; 95% CI, 1.00-1.03; P = .02) and decreased suicide-specific survival (hazards ratio, 1.02; 95% CI, 1.00-1.03, P = .01) in prognosis-adjusted models. In this sample of cancer patients in the Surveillance, Epidemiology, and End Results database, patients that undergo high-morbidity surgeries appear most vulnerable to death by suicide. The identification of this high-risk cohort should motivate health care providers and particularly surgeons to adopt screening measures during the postoperative follow-up period for these patients.

    Post-operative adhesions after gastrointestinal surgery are responsible for significant morbidity and constitute an important public health problem. The aim of this study was to review the surgical literature to determine the incidence, consequences and the variety of possible countermeasures to prevent adhesion formation. A systematic review of English and French language surgical literature published between 1995 and 2009 was performed using the keywords "adhesion" and "surgery". Peritoneal adhesions are reported as the cause of 32% of acute intestinal obstruction and 65-75% of all small bowel obstructions. It is estimated that peritoneal adhesions develop after 93-100% of upper abdominal laparotomies and after 67-93% of lower abdominal laparotomies. Nevertheless, only 15-18% of these adhesions require surgical re-intervention. The need for re-intervention for adhesion-related complications varies depending on the initial type of surgery, the postoperative course and the type of incision. The laparoscopic approach appears to decrease the risk of adhesion formation by 45% and the need for adhesion-related re-intervention to 0.8% after appendectomy and to 2.5% after colorectal surgery. At the present time, only one product consisting of hyaluronic acid applied to a layer of carboxymethylcellulose (Seprafilm(®)) has been shown to significantly reduce the incidence of postoperative adhesion formation; but this product is also associated with a significant increase in the incidence of anastomotic leakage when the membrane is applied in direct contact with the anastomosis. The use of this product has not been shown to decrease the risk of re-intervention for bowel obstruction. The prevention of postoperative adhesions is an important public health goal, particularly in light of the frequency of this complication. The routine use of anti-adhesion products is not recommended given the lack of studies with a high level of evidence concerning their efficacy and safety of

    The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

  5. The Role of Thyroid Hormone Signaling in the Prevention of Digestive System Cancers

    Full Text Available Thyroid hormones play a critical role in the growth and development of the alimentary tract in vertebrates. Their effects are mediated by nuclear receptors as well as the cell surface receptor integrin αVβ3. Systemic thyroid hormone levels are controlled via activation and deactivation by iodothyronine deiodinases in the liver and other tissues. Given that thyroid hormone signaling has been characterized as a major effector of digestive system growth and homeostasis, numerous investigations have examined its role in the occurrence and progression of cancers in various tissues of this organ system. The present review summarizes current findings regarding the effects of thyroid hormone signaling on cancers of the esophagus, stomach, liver, pancreas, and colon. Particular attention is given to the roles of different thyroid hormone receptor isoforms, the novel integrin αVβ3 receptor, and thyroid hormone-related nutrients as possible protective agents and therapeutic targets. Future investigations geared towards a better understanding of thyroid hormone signaling in digestive system cancers may provide preventive or therapeutic strategies to diminish risk, improve outcome and avert recurrence in afflicted individuals.

    Extracellular digestive processes were examined in the Dungeness crab, Cancer magister and the blue crab, Callinectes sapidus, during hyposaline exposure. Both species are found in estuaries as adults, but vary in their ability to balance the cardiovascular and respiratory demands of concurrent osmoregulation and digestion. The weak osmoregulator, C. magister, is unable to balance the demands of osmoregulation and digestion. Concordant with observed decreases in oxygen consumption and mechanical digestion, proteolytic digestion within the foregut and hepatopancreas was delayed, resulting in a relative reduction of circulating amino acids post-feeding in low salinity. In contrast, the efficient osmoregulator, C. sapidus, balances the demands of osmoregulation and digestion, and mechanical digestion continues unabated in low salinity. Protease activity in the gut fluid and hepatopancreas showed either no change or a reduction over time. The transport of amino acids into the cells post-feeding is opposed by an efflux of amino acids at the cellular level, and resulted in a build up of amino acids in the hemolymph. Despite differences in the extracellular responses to low salinity exposure following feeding, both species were able to maintain high digestive efficiencies. © 2013.

    The role of surgery cannot be discussed independently, but in relationship to the other modalities of treatment. Sentinel lymph node mapping and biopsy has revolutionized the role of surgery in axillary staging. Techniques of sentinel node mapping, the timing relative to chemotherapy, possible contraindications, and the necessity of completion axillary dissection are all under active investigation. The next few years will see continued changes in this important technique. Techniques of localizing clinically occult tumors are numerous and under study. These are not yet at the level of Phase III comparative trials. Induction chemotherapy has long been standard care for women with locally advanced breast cancer. It has not become standard care for Stage I or II breast cancers that meet criteria for adjuvant therapy. The ability to significantly downsize 80% of breast cancers is reason enough to make it usual practice for women who are certain to receive chemotherapy, if only for the cosmetic advantage that would accrue. Much has been made of the use of thermal ablation of small breast cancers by small probes introduced by skin puncture. In initial trials the lesions were excised after being heated or frozen. Current studies are leaving the destroyed tissue in place and following for evidence of control or recurrence. The value of this approach in terms of cosmesis is unproven, and the timing of its introduction when small tumors are being evaluated for margins and genetic markers, make it difficult to imagine broad acceptance. Finally, the role of prophylactic surgery for women at increased risk remains a difficult equation, compounded of alternatives such as chemoprevention, availability and effectiveness of surveillance techniques, and the level of fear and anxiety of the patient.

The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery.Results: Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001, but the time to soft food intake (6.0 vs 6.6 days, P=0.036 and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018 were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001. The 5-year overall survival (90.8% vs 88.6%, P=0.540 and disease-free survival (86.1% vs 78.9%, P=0.201 rates were similar in both groups.Conclusion: The present study showed that laparoscopic surgery is associated

    Robotic surgery is increasingly used to resect lung cancer. However costs are high. We compared costs and outcomes for robotic surgery, video-assisted thoracic surgery (VATS), and open surgery, to treat non-small cell lung cancer (NSCLC). We retrospectively assessed 103 consecutive patients given lobectomy or segmentectomy for clinical stage I or II NSCLC. Three surgeons could choose VATS or open, the fourth could choose between all three techniques. Between-group differences were assessed by Fisher's exact, two-way analysis of variance (ANOVA), and Wilcoxon-Mann-Whitney test. P values open surgery. Age, physical status, pulmonary function, comorbidities, stage, and perioperative complications did not differ between the groups. Pathological tumor size was greater in the open than VATS and robotic groups (P=0.025). Duration of surgery was 150, 191 and 116 minutes, by robotic, VATS and open approaches, respectively (Popen groups. Estimated costs were 82%, 68% and 69%, respectively, of the regional health service reimbursement for robotic, VATS and open approaches. Robotic surgery for early lung cancer was associated with shorter stay and more extensive lymph node dissection than VATS and open surgery. Duration of surgery was shorter for robotic than VATS. Although the cost of robotic thoracic surgery is high, the hospital makes a profit.

    Surgery is a mainstay treatment for patients with solid tumours. However, despite surgical resection with a curative intent and numerous advances in the effectiveness of (neo)adjuvant therapies, metastatic disease remains common and carries a high risk of mortality. The biological perturbations that accompany the surgical stress response and the pharmacological effects of anaesthetic drugs, paradoxically, might also promote disease recurrence or the progression of metastatic disease. When cancer cells persist after surgery, either locally or at undiagnosed distant sites, neuroendocrine, immune, and metabolic pathways activated in response to surgery and/or anaesthesia might promote their survival and proliferation. A consequence of this effect is that minimal residual disease might then escape equilibrium and progress to metastatic disease. Herein, we discuss the most promising proposals for the refinement of perioperative care that might address these challenges. We outline the rationale and early evidence for the adaptation of anaesthetic techniques and the strategic use of anti-adrenergic, anti-inflammatory, and/or antithrombotic therapies. Many of these strategies are currently under evaluation in large-cohort trials and hold promise as affordable, readily available interventions that will improve the postoperative recurrence-free survival of patients with cancer.

    Full Text Available Breast cancer is the most common type of cancer among women in the whole world. It is caused by the development of malignant cells in the breast. In cancer patients, physical therapy has resulted in improved physical functioning, cardiovascular fitness, sleep, quality of life, psychological and social well-being, and self esteem, and significant decreases in fatigue, anxiety and depression. Aim: The aim of this study is to underline the importance of physical therapy in the rehabilitation of patients after total mastectomy surgery in breast cancer. Material and methods: We investigated 14 women aged between 45 and 75 years old, diagnosed with breast cancer (stages I–III, having a total mastectomy surgery 6 months ago. At the beginning and after 2 weeks of intervention, the subject`s evaluations consisted in: each patient was evaluated in regard to shoulder flexibility (from Test 1 to Test 8; on the other hand, we measured the upper limb circumferences on the surgery side. The physical therapy programme consisted in 10 sessions of 20 minutes lymphatic drainage and 10 minutes individualized physical therapy programmes. Results: At the end of intervention, it was observed a score improvement at Test 2 (from 1.28±0.99 to 1.85±0.53, p=0.041, Test 3 (from 0.42±0.85 to 1.57±0.85, p=0.001, Test 7 (from 0.5±0.51 to 0.85±0.36, p=0.019 and Test 8 (from 1.28±0.99 to 1.85±0.53, p=0.041.

    Curative resection of extrahepatic bile duct cancer and pancreatoduodenal cancer is very difficult, and its long term result is pessimistic. Twenty patients with bile duct cancer (12 resected and 8 non-resected) and 23 patients with pancreatoduodenal cancer (10 resected and 13 non-resected) were treated with extracorporeal Cobalt-60 irradiation following the surgery. The just opposed anterior and posterior ports were used with the field size ranging from 6 x 6 cm to 13 x 14 cm. The delivered doses ranged from 46 to 60 Gy (70 - 108TDF) for bile duct cancer, and from 18 to 66 Gy (28 - 104TDF) for pancreatoduodenal cancer. On one of resected and 4 of non-resected patients with pancreatoduodenal cancer, the therapeutic schedule could not be pursued completely because of decreased leucocytes and emaciation. The postoperative survivals were compared between the cases with and without adjunctive radiotherapy. The longest and mean survivals of the patients with resected bile duct cancer were 41 mos. and 20 mos. respectively, in the irradiated v.s. 21 mos. and 14 mos. in the non-irradiated group. The mean survival of the patients without resection of bile duct cancer was 15 mos. in the irradiated v.s. 6 mos. in the non-irradiated group; one resected case has survived more than 61 mos. after radiotherapy and is still alive. The mean survival after resection of pancreatoduodenal cancer was 16 mos. in the irradiated v.s. 11 mos. in non-irradiated group, and 3 in the former are still alive, one having survived the longest 50 mos. The longest and mean survival of the patients without resection of pancreatoduodenal cancer were 22 mos. and 8 mos. respectively v.s. 7 mos. and 4 mos. of the non-irradiated patients. Advantageous effects of radiotherapy combined with surgery for bile duct cancer and pancreatoduodenal cancer were observed throughout this clinical study. (author)

    Minimally invasive surgery widely used to treat benign disorders of the digestive system, has become the focus of intense study in recent years in the field of surgical oncology. Since then, the experience with this kind of approach has grown, aiming to provide the same oncological outcomes and survival to conventional surgery. Regarding gastric cancer, surgery is still considered the only curative treatment, considering the extent of resection and lymphadenectomy performed. Conventional surgery remains the main modality performed worldwide. Notwithstanding, the role of the minimally invasive access is yet to be clarified. To evaluate and summarize the current status of minimally invasive resection of gastric cancer. A literature review was performed using Medline/PubMed, Cochrane Library and SciELO with the following headings: gastric cancer, minimally invasive surgery, robotic gastrectomy, laparoscopic gastrectomy, stomach cancer. The language used for the research was English. 28 articles were considered, including randomized controlled trials, meta-analyzes, prospective and retrospective cohort studies. Minimally invasive gastrectomy may be considered as a technical option in the treatment of early gastric cancer. As for advanced cancer, recent studies have demonstrated the safety and feasibility of the laparoscopic approach. Robotic gastrectomy will probably improve outcomes obtained with laparoscopy. However, high cost is still a barrier to its use on a large scale. A cirurgia minimamente invasiva amplamente usada para tratar doenças benignas do aparelho digestivo, tornou-se o foco de intenso estudo nos últimos anos no campo da oncologia cirúrgica.

    Full Text Available Introduction: The incidence of malnutrition in hospitalized patients is reported to be high. In particular, patients with esophageal cancer are prone to malnutrition, due to preoperative digestive system dysfunctions and short-term non-oral feeding postoperatively. Selection of an appropriate method for feeding in the postoperative period is important in these patients.   Materials and Methods: In this randomized clinical trial, 40 patients with esophageal cancer who had undergone esophagectomy between September 2008 and October 2009 were randomly assigned into either enteral feeding or parenteral feeding groups, with the same calorie intake in each group. The level of serum total protein, albumin, prealbumin, transferrin, C3, C4 and hs-C-reactive protein          (hs-CRP, as well as the rate of surgical complications, restoration of bowel movements and cost was assessed in each group.   Results: Our results showed that there was no significant difference between the groups in terms of serum albumin, prealbumin or transferrin. However, C3 and C4 levels were significantly higher in the enteral feeding group compared with the parenteral group, while hs-CRP level was significantly lower in the enteral feeding group. Bowel movements were restored sooner and costs of treatment were lower in the enteral group. Postoperative complications did not differ significantly between the groups. There was one death in the parenteral group 10 days after surgery due to myocardial infarction.   Conclusion:  The results of our study showed that enteral feeding can be used effectively in the first days after surgery, with few early complications and similar nutritional outcomes compared with the parenteral method. Enteral feeding was associated with reduced inflammation and was associated with an improvement in immunological responses, quicker return of bowel movements, and reduced costs in comparison with parenteral feeding.

    We report the case of a patient with pyogenic spondylodiscitis after transoral surgery for oropharyngeal cancer. The patient was a 66-year-old man with a history of hepatic cell carcinoma, alcoholic cirrhosis, and chronic pancreatitis. The tumor was resected via a transoral approach with concurrent bilateral elective neck dissections. Although the initial postoperative course was uneventful, the patient experienced severe cervical pain because of which he revisited the hospital. The patient was diagnosed with pyogenic spondylodiscitis, according to the results of magnetic resonance imaging. Continuous treatment with parenteral antibiotics and a cervical brace was required for 2 months before all his symptoms and signs diminished. To the best of our knowledge, this is the first reported case of pyogenic spondylodiscitis as a complication of transoral resection for head and neck cancer. Copyright © 2012 Elsevier Ireland Ltd.

Most of investigated counties (eight with high FSPWQG (>50% distributed in the northern region of the HRB and had larger CMs of digestive tract cancers. In addition to their similar spatial distribution, significant correlations between FSP indices and CMs were observed by controlling for drinking water safety (DWS, gross domestic product (GDP, and population (POP. Furthermore, the above-mentioned partial correlations were clearly increased when only controlling for GDP and POP. Our study indicated that county-level variations of digestive cancer mortality are remarkably associated with water pollution, and suggested that continuous measures for improving surface water quality and DWS and hygienic interventions should be effectively implemented by local governments.

    Full Text Available Abstract 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

    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.

    Full Text Available High throughput methodologies have revealed the existence of an unexpectedly large number of long noncoding RNAs (lncRNAs. The unconventional role of lncRNAs in gene expression regulation and their broad implication in oncogenic and tumor suppressive pathways have introduced lncRNAs as novel biological tumor markers. The most prominent example of lncRNAs application in routine clinical practice is PCA3, a FDA-approved biomarker for prostate cancer. Regarding digestive system malignancies, the oncogenic HOTAIR is one of the most widely studied lncRNAs in the preclinical level and has already been identified as a potent prognostic marker for major malignancies of the gastrointestinal tract. Here, we provide an overview of recent findings regarding the emerging role of lncRNAs not only as key regulators of cancer initiation and progression in colon, stomach, pancreatic, liver, and esophageal cancers, but also as reliable tumor markers and therapeutic tools. lncRNAs can be easily, rapidly, and cost-effectively determined in tissues, serum, and gastric juice, making them highly versatile analytes. Taking also into consideration the largely unmet clinical need for early diagnosis and more accurate prognostic/predictive markers for gastrointestinal cancer patients, we comment upon the perspectives of lncRNAs as efficient molecular tools that could aid in the clinical management.

    Purpose: The role of radiotherapy in the management of patients with locoregional recurrent cervix cancer after radical surgery were retrospectively analyzed. Methods and materials: Twenty-eight patients treated with radiotherapy for locoregional recurrence after primary surgery for carcinoma of the cervix between 1989 and 1993 were analyzed. The median follow-up of survivors was 15 months (ranged 7-43 months). Eight patients had their disease confined to the vagina and 19 patients(68%) had pelvic mass as part of their locoregional recurrent disease. Within 24 months after the initial surgery, 82% of recurrences manifested themselves. All patients had whole pelvic irradiation with or without intracavitary radiotherapy(ICR). Results: Complete response(CR) was achieved in 18 patients(64%). Five of eighteen patients(28%) with initial CR developed second locoregional recurrence. Response to radiotherapy correlated strongly with tumor volume, site of recurrence and total radiation dose. The overall 2 year survival rate was 43% and the disease free survival was 31%. Survival rate was significantly influenced by the factors of interval from operation to recurrence, size and site of recurrent tumor, radiation dose, response of radiotherapy, lymph node status as initial presentation. The principal cause of death was lung metastasis(36%). Conclusion: Radiotherapy is an excellent modality for control of locoregional recurrent cervix cancer. To improve local control and survival rate, whole pelvic external radiotherapy in addition to ICR with more than 75.0Gy at the depth of 1.0cm from vaginal mucosa is needed and frequent follow up and early detection of recurrence is suggested as well

    Laparoscopic technology is gradually accepted in gastric cancer surgery, whose efficacy has been demonstrated by some clinical researches. Randomized controlled trials (RCT) are considered as the most important evidence to prove clinical outcomes of laparoscopic surgery for gastric cancer. Korean gastric surgeons have made great contributions to RCT in laparoscopic gastric cancer surgery. KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group) is one of the most important forerunner and global leader of clinical trials of gastric cancer treatment. KLASS series clinical trials are attracting global attention because of the significant value of surgical treatment for gastric cancer. The RCTs in Korea involve in many aspects of laparoscopic gastrectomy for gastric cancer, including laparoscopy application in early gastric cancer (KLASS-01, KLASS-03 and KLASS-07), advanced gastric cancer (KLASS-02 and KLASS-06), function-preserving gastrectomy (KLASS-04,KLASS-05) and sentinel node navigation surgery (SENORITA trial). In order to share some informations of these RCTs, we review and prospect some important clinical trials of laparoscopic gastric cancer surgery in Korea. With the experience of Korean gastric surgeons, we can make more progress in our own clinical trials of laparoscopic gastric cancer surgery.

    The Hedgehog (Hh) signaling pathway has recently been reported to be associated with the prognosis of digestive system cancers. However, the results are inconsistent. This study aimed to investigate the association between Hh pathway components and survival outcomes in patients with digestive system cancers. We conducted a comprehensive retrieval in PubMed, EMBASE and Cochrane library for relevant literatures until May 1st, 2015. The pooled hazard ratios (HRs) for overall survival (OS) and disease-free survival (DFS) with 95% confidence intervals (CIs) were calculated to clarify the prognostic value of Hh pathway components, including Shh, Gli1, Gli2, Smo and Ptch1. A total of 16 eligible articles with 3222 patients were included in the meta-analysis. Pooled HR suggested that over-expression of Shh and Gli1 were both associated with poor OS (HR = 1.87, 95% CI: 1.14-3.07 and HR = 1.96, 95% CI: 1.66-2.32, respectively) and DFS (HR = 2.37, 95% CI: 1.19-4.72 and HR = 2.18, 95% CI: 1.61-2.96, respectively). In addition, over-expression of Smo was associated with poor DFS (HR = 1.38, 95% CI: 1.08-1.75). This study reveals that over-expressed Hh pathway components, including Shh, Gli1 and Smo, are associated with poor prognosis in digestive system cancer patients. Hh signaling pathway may become a potential therapeutic target in digestive system cancers.

    Many studies have reported the association between tumor necrosis factor-α (TNF-α)-238 polymorphism and digestive system cancer susceptibility, but the results were inconclusive. We performed a meta-analysis to derive a more precise estimation of the relationship between TNF-α-238 G/A polymorphism and digestive system cancer risk. Pooled analysis for the TNF-α-238 G/A polymorphism contained 26 studies with a total of 4849 cases and 8567 controls. The meta-analysis observed a significant association between TNF-α-238 G/A polymorphism and digestive system cancer risk in the overall population (GA vs GG: OR 1.19, 95 % CI 1.00-1.40, P heterpgeneity = 0.016; A vs G: OR 1.19, 95 % CI 1.03-1.39, P heterpgeneity = 0.015; dominant model: OR 1.20, 95 % CI 1.02-1.41, P heterpgeneity = 0.012). In the analysis of the ethnic subgroups, however, similar results were observed only in the Asian population, but not in the Caucasian population. Therefore, this meta-analysis suggests that TNF-α-238 G/A polymorphism is associated with a significantly increased risk of digestive system cancer. Further large and well-designed studies are needed to confirm these findings.

    Full Text Available Colorectal cancer (CRC is a major cause of worldwide morbidity and mortality. Surgical treatment is common, and there is a great need to improve the delivery of such care. The gold standard for evaluating surgery is within well-designed randomized controlled trials (RCTs; however, the impact of RCTs is diminished by a lack of coordinated outcome measurement and reporting. A solution to these issues is to develop an agreed standard "core" set of outcomes to be measured in all trials to facilitate cross-study comparisons, meta-analysis, and minimize outcome reporting bias. This study defines a core outcome set for CRC surgery.The scope of this COS includes clinical effectiveness trials of surgical interventions for colorectal cancer. Excluded were nonsurgical oncological interventions. Potential outcomes of importance to patients and professionals were identified through systematic literature reviews and patient interviews. All outcomes were transcribed verbatim and categorized into domains by two independent researchers. This informed a questionnaire survey that asked stakeholders (patients and professionals from United Kingdom CRC centers to rate the importance of each domain. Respondents were resurveyed following group feedback (Delphi methods. Outcomes rated as less important were discarded after each survey round according to predefined criteria, and remaining outcomes were considered at three consensus meetings; two involving international professionals and a separate one with patients. A modified nominal group technique was used to gain the final consensus. Data sources identified 1,216 outcomes of CRC surgery that informed a 91 domain questionnaire. First round questionnaires were returned from 63 out of 81 (78% centers, including 90 professionals, and 97 out of 267 (35% patients. Second round response rates were high for all stakeholders (>80%. Analysis of responses lead to 45 and 23 outcome domains being retained after the first and

    Kidney transplant recipients are at increased risk of developing cancer in comparison with the general population. To effectively manage post-transplantation malignancies, it is essential to proactively monitor patients. A long-term intensive screening program was associated with a reduced incidence of cancer after transplantation. This study evaluated the usefulness of the gene expression profiling of peripheral blood samples obtained from kidney transplant patients and adopted a screening test for detecting cancer of the digestive system (gastric, colon, pancreas, and biliary tract). Nineteen patients were included in this study and a total of 53 gene expression screening tests were performed. The gene expression profiles of blood-delivered total RNA and whole genome human gene expression profiles were obtained. We investigated the expression levels of 2665 genes associated with digestive cancers and counted the number of genes in which expression was altered. A hierarchical clustering analysis was also performed. The final prediction of the cancer possibility was determined according to an algorithm. The number of genes in which expression was altered was significantly increased in the kidney transplant recipients in comparison with the general population (1091 ± 63 vs 823 ± 94; P = .0024). The number of genes with altered expression decreased after the induction of mechanistic target of rapamycin (mTOR) inhibitor (1484 ± 227 vs 883 ± 154; P = .0439). No cases of possible digestive cancer were detected in this study period. The gene expression profiling of peripheral blood samples may be a useful and noninvasive diagnostic tool that allows for the early detection of cancer of the digestive system.

    Full Text Available Many studies have reported the prognostic predictive value of CD166 as a cancer stem cell marker in cancers of the digestive system; however, its predictive value remains controversial. Here, we investigate the correlation between CD166 positivity in digestive system cancers and clinicopathological features using meta-analysis.A comprehensive search in PubMed and ISI Web of Science through March of 2013 was performed. Only articles containing CD166 antigen immunohistochemical staining in cancers of the digestive system were included,including pancreatic cancer, esophageal cancer, gastric cancer and colorectal cancer. Data comparing 3- and 5-year overall survival along with other clinicopathological features were collected.Nine studies with 2553 patients who met the inclusion criteria were included for the analysis. The median rate of CD166 immunohistochemical staining expression was 56% (25.4%-76.3%. In colorectal cancer specifically, the results of a fixed-effects model indicated that CD166-positive expression was an independent marker associated with a smaller tumor burden (T category; RR = 0.93, 95%, CI: 0.88-0.98 but worse spread to nearby lymph nodes (N category; RR = 1.17, 95% CI: 1.05-1.30. The 5-year overall survival rate was showed relationship with cytoplasmic positive staining of CD166 (RR = 1.47 95% 1.21-1.79, but no significant association was found in the pool or any other stratified analysis with 3- or 5- year overall survival rate.Based on the published studies, different cellular location of CD166 has distinct prognostic value and cytoplasmic positive expression is associated with worse prognosis outcome. Besides, our results also find CD166 expression indicate advanced T category and N-positive status in colorectal cancer specifically.

    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.

    Objective The goal of this study is to determine the effect of primary surgery vs radiotherapy (RT) on overall survival (OS) in patients with early stage oral cavity squamous cell carcinoma (OCSCC). In addition, this study attempts to identify factors associated with receiving primary RT. Study Design Retrospective cohort study. Setting National Cancer Database (NCDB, 2004-2013). Subjects and Methods Reviewing the NCDB from 2004 to 2013, patients with early stage I to II OCSCC were identified. Kaplan-Meier estimates of survival, Cox regression analysis, and propensity score matching were used to examine differences in OS between primary surgery and primary RT. Multivariable logistic regression analysis was performed to identify factors associated with primary RT. Results Of the 20,779 patients included in the study, 95.4% (19,823 patients) underwent primary surgery and 4.6% (956 patients) underwent primary RT. After adjusting for covariates, primary RT was associated with an increased risk of mortality (adjusted hazard ratio [aHR], 1.97; 99% confidence interval [CI], 1.74-2.22). On multivariable analysis, factors associated with primary RT included age ≥70 years, black race, Medicaid or Medicare insurance, no insurance, oral cavity subsite other than tongue, clinical stage II disease, low-volume treatment facilities, and earlier treatment year. Conclusion Primary RT for early stage OCSCC is associated with increased mortality. Approximately 5% of patients receive primary RT; however, this percentage is decreasing. Patients at highest risk for receiving primary RT include those who are elderly, black, with public insurance, and treated at low-volume facilities.

    This paper presents long-term results from a randomized trial of pre- or postoperative megavoltage radiation therapy versus surgery alone in pre- and postmenopausal women with operable breast cancer. Treatment outcome after relapse among patients who developed loco-regional recurrences was also analyzed. A total of 960 patients were included in the trial. The mean follow-up was 16 years (range: 13-19 years). The radiation therapy was individually planned. It included the chest wall (and the breast in the preoperative cases) and the regional lymph nodes. The tumor dose was 45 Gy/5 weeks. No adjuvant systemic therapy was used. The results showed a significant benefit with radiation therapy in terms of recurrence-free survival during the entire follow-up period. There was also an overall survival difference - corresponding to 16% reduction of deaths - in favour of the irradiated patients which, however, was not statistically significant (p=0.09). Among those 169 patients who developed loco-regional recurrences long-term control was only achieved in about one-third of the cases. This figure was similar among those who had received adjuvant radiation therapy (34%) compared to those initially treated with surgery alone (32%). This implied that the overall proportion of patients who eventually developed uncontrolled local disease was significantly higher among those initially allocated to surgery alone (16%) compared to those allocated to pre- or postoperative radiation therapy (6%, p<0.01). These results suggest that local undertreatment may be deleterious in subgroups of patients. (author) 5 tabs

    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. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Patients with cancer and patients undergoing major orthopedic procedures are two groups at risk of deep venous thrombosis (DVT). The objective was to determine the rate of venous thromboembolic disease in patients with a malignant neoplasm and major orthopaedic surgery of the lower limb. The study included 169 patients. All patients were given knee-high intermittent pneumatic compression devices for prophylaxis. Postoperative surveillance for thrombosis was performed on all patients with venous duplex doppler ultrasonography. Proximal DVT occurred in 24 of 169 patients (14.2%). One patient (0.6%) developed a symptomatic, nonfatal pulmonary embolus (PE). The development of DVT was not associated with age, sex, type of surgery, type of neoplasm, location, or pathologic fracture. The addition of anticoagulant medication such as warfarin did not significantly reduce the rate of DVT in a subset of 54 patients. In three patients, the DVT occurred only in the contralateral limb, and in four patients, there were bilateral DVTs. When intermittent compression boots were used for prophylaxis in conjunction with ultrasound screening, the risk of proximal DVT was substantial (14.2%), but the rate of symptomatic PE was low (0.6%).

    To identify the length of perioperative fasting among patients submitted to gastrointestinal cancer surgeries. Retrospective cohort study, developed by consulting the medical records of 128 patients submitted to gastrointestinal cancer surgeries. The mean of total length of fasting was 107.6 hours. The total length of fasting was significantly associated with the number of symptoms presented before (p=0.000) and after the surgery (p=0.007), the length of hospital stay (p=0.000), blood transfusion (p=0.013), nasogastric tube (p=0.001) and nasojejunal tube (p=0,003), postoperative admission at ICU (p=0.002), postoperative death (p=0.000) and length of preoperative fasting (p=0.000). The length of fasting is associated with complications that affect the quality of the patients' postoperative recovery and nurses' work. The nursing team should be alert to this aspect and being responsible for overseeing the patients' interest, should not permit the unnecessary extension of fasting.

  3. Utilising cardiopulmonary bypass for cancer surgery. Malignancy-induced protein C deficiency and thrombophilia.

    LENUS (Irish Health Repository)

    Marshall, C

    2012-02-03

    Cardiopulmonary bypass has evolved over the last 30 years. It is an important tool for the cardiac surgeon today and also has applications in non-cardiac operations such as surgery to extract tumours. Such patients undergoing surgery for cancer may be at an increased risk of a thromboembolic event post surgery, due to disturbances in the normal clotting pathway leading to hypercoagulability. One such disturbance is malignancy-induced Protein C deficiency. A deficiency of Protein C can cause hypercoagulabitity. Recent studies have examined cardiopulmonary bypass and inherited Protein C deficiency. However, surgery for cancer patients with a malignancy-induced Protein C deficiency involving cardiopulmonary bypass has not been reported. Surgery using CPB in these patients may result in increased morbidity and mortality. The objective of this article is to review the literature in order to discuss the occurrence, the aetiology and possible management of cancer patients with malignancy-induced Protein C deficiencies that require cardiopulmonary bypass for their surgery.

    Objective: To describe the presentation and pathology of rectal cancer, and to evaluate the local experience after total meso rectal excision at a tertiary care hospital in Pakistan. Methodology: A retrospective study of two hundred cases of carcinoma rectum that had undergone total meso rectal excision at Liaquat University Hospital Jamshoro Pakistan was carried out from January 1998 to December 2007.The cases were admitted through outpatient and emergency departments. The demographic details of each patient and variables such as clinical presentation, tumor location, Dukes staging, TNM staging, operations and complications were recorded on proformas. Each patient was followed up at two months for one year, every four months for three years and annually thereafter. Results: Male to female ratio being almost equal 1.6:1, Age ranged from 14-70 years. Site of tumor at upper one third 25%, middle one third 30% and lower one third 45%. Majority of patients (more than 62%) were in Dukes B Group.There were no postoperative deaths, complications occurred in a total of 59 (29.5%) patients, which were mostly colostomy related (13.0%). The abdominal wound infection 5%, anastomotic dehiscence 1.0%, urinary tract infection 5%, and impotence occurred in 1.5%. In 20% patients local recurrence was detected. Conclusion: Total meso rectal excision is a safe and feasible technique for rectal cancer surgery with acceptable perioperative morbidity and adequate local disease control. (author)

    Increasingly more jurisdictions worldwide are legalizing medical cannabis. Major concerns related to such policies are that improper storage and disposal arrangements may lead to the diversion and unintentional digestion of cannabis. These concerns are particularly acute among patients with cancer because they take home medical cannabis for extended periods and have high rates of treatment termination and mortality shortly after the onset of treatment with medical cannabis. Therefore, leftover cannabis is potentially particularly prevalent, and potentially improperly stored, in households of current and deceased patients with cancer. The current study investigated the risk of medical cannabis diversion and unintentional digestion among oncology patients treated with medical cannabis and caregivers of recently deceased patients who were treated with medical cannabis. A total of 123 oncology patients treated with medical cannabis and 37 caregivers of deceased oncology patients treated with medical cannabis were interviewed regarding practices and the information received concerning the safe storage and disposal of medical cannabis, as well as experiences of theft, diversion, and unintentional digestion. High rates of suboptimal storage were reported and caregivers were found to be particularly unlikely to have received information regarding the safe storage and disposal of medical cannabis. Few incidences of theft, diversion, and unintentional digestion were reported. Oncologists and other health care providers have an important, yet unfilled, role to play with regard to educating patients and caregivers of the importance of the safe storage and disposal of medical cannabis. Interventions designed to alert patients treated with medical cannabis and their caregivers to the problem of diversion, along with strategies to limit it, have the potential to limit diversion and unintentional exposure to medical cannabis.

    Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. This study evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer. Analysis of the medical records of patients who underwent laparoscopic colorectal resection from August 2004 to November 2007 was made. Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively. Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer. Surgical outcomes and pathologic outcomes were compared between transverse colon cancer (TCC) and other site colon cancer (OSCC). Of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for OSCC, and 34 patients underwent laparoscopic surgery for TCC. Patients with TCC were similar to patients with OSCC in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, distal resection margin, proximal resection margin, number of lymph nodes, and radial margin. One case in TCC and three cases in OSCC were converted to open surgery. Laparoscopic surgery for transverse colon cancer and OSCC had similar peri-operative clinical and acceptable pathological outcomes.

    In locally advanced oral cancer, the main modalities of treatment, e.g. surgery and radiotherapy, most often fail to control the disease when used singly. A combination policy of surgery and radiotherapy achieves adequate control of the disease. In order to improve the results in advanced oral cancer, chemotherapy given prior to and during radiation treatment and judicious combination of surgery offer the best possible approach in the management. The experience in the combination policy in the treatment of oral cancer in Northern India is dealt with. (auth.)

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

    Full Text Available Introduction. Ambulatory surgery is not commonly practiced in Asia. A 23-hour ambulatory (AS23 service was implemented at our institute in March 2004 to allow more surgeries to be performed as ambulatory procedures. In this study, we reviewed the impact of the AS23 service on breast cancer surgeries and reviewed surgical outcomes, including postoperative complications, length of stay, and 30-day readmission. Methods. Retrospective review was performed of 1742 patients who underwent definitive breast cancer surgery from 1 March 2004 to 31 December 2010. Results. By 2010, more than 70% of surgeries were being performed as ambulatory procedures. Younger women (P<0.01, those undergoing wide local excision (P<0.01 and those with ductal carcinoma-in situ or early stage breast cancer (P<0.01, were more likely to undergo ambulatory surgery. Six percent of patients initially scheduled for ambulatory surgery were eventually managed as inpatients; a third of these were because of perioperative complications. Wound complications, 30-day readmission and reoperation rates were not more frequent with ambulatory surgery. Conclusion. Ambulatory breast cancer surgery is now the standard of care at our institute. An integrated workflow facilitating proper patient selection and structured postoperativee outpatient care have ensured minimal complications and high patient acceptance.

    Previous studies have reported an association between the two coding polymorphisms (91T>A and 169G>A) of the serine/threonine kinase 15 (STK15) gene and the risk of digestive system cancers; however, the results are inconsistent. In the present study, a meta-analysis was carried out to assess the association between the two STK15 polymorphisms and the risk of digestive system cancers. Relevant studies were identified using PubMed, Web of Science, China National Knowledge Infrastructure, WanFang and VIP databases up to February 18, 2014. The pooled odds ratio (OR) with a 95% confidence interval (CI) was calculated using the fixed or random effects model. A total of 15 case-control studies from 14 publications were included. Of these, 15 studies concerned the 91T>A polymorphism and included 7,619 cases and 7,196 controls and four studies concerned the 161G>A polymorphism and included 826 cases and 713 controls. A significantly increased risk of digestive system cancers was observed for the 91T>A polymorphism (recessive model: OR, 1.19; 95% CI, 1.07-1.31). In subgroup analysis by ethnicity, a significant association was detected in Asian populations (recessive model: OR, 1.21; 95% CI, 1.08-1.36) but not in Caucasian and mixed populations. Stratification by tumor type indicated that the 91T>A polymorphism was associated with an increased risk of esophageal and colorectal cancers under the recessive model (OR, 1.19; 95% CI, 1.03-1.38; and OR, 1.24; 95% CI, 1.04-1.46; respectively); however, no significant association was observed between the 169G>A polymorphism and the risk of digestive system cancers in any of the genetic models. Furthermore, in subgroup analysis by ethnicity, similar results were observed in the Asian and Caucasian populations. The present meta-analysis demonstrated that the STK15 gene 91T>A polymorphism, but not the 169G>A polymorphism, may be a risk factor for digestive system cancers, particularly for esophageal and colorectal cancers.

    Following a national audit of rectal cancer management in 2007, a national centralization program in the Republic of Ireland was initiated. In 2010, a prospective evaluation of rectal cancer treatment and early outcomes was conducted. A total of 29 colorectal surgeons in 14 centers prospectively collated data on all patients with rectal cancer who underwent curative surgery in 2010. Data were available on 447 patients who underwent proctectomy with curative intent for rectal cancer in 2010; 23.7 % of patients underwent abdominoperineal excision. The median number of lymph nodes identified was 12. The 30-day mortality rate was 1.1 %. Compared with 2007, there was a reduction in positive circumferential margin rate (15.8 vs 4.5 %, P rectal cancer. Patients undergoing rectal cancer surgery in hospitals following a national centralization initiative received high-quality surgery. Significant heterogeneity exists in radiotherapy administration, and evidence-based guidelines should be developed and implemented.

    Xenopus kinesin-like protein 2 (TPX2) is a microtubule-associated protein that plays an important role in spindle assembly and dynamics. However, the clinical and prognostic value of TPX2 in the digestive system cancers remains unclear. The objective of this review was to evaluate the association of TPX2 expression with disease-free survival (DFS), overall survival (OS), and clinicopathological features of digestive system cancers. The software Stata 12.0 was used to analyze the outcomes, including OS, disease-free survival (DFS), and clinicopathological characteristics. A total of 10 eligible studies with 906 patients were included. Elevated TPX2 expression was significantly associated with poor DFS (pooled hazard ratio [HR] =2.48, 95% confidence interval [CI]: 1.96-3.13) and OS (pooled HR =2.66, 95% CI: 2.04-3.48) of digestive system malignancies. Subgroup analyses showed that cancer type, sample size, study quality, and laboratory detection methods did not alter the significant prognostic value of TPX2. Additionally, TPX2 expression was found to be an independent predictive factor for DFS (HR =2.31, 95% CI: 1.78-3.01). TPX2 expression might be associated with TNM stage and pathological grade in digestive system cancer. In conclusion, TPX2 is an independent prognostic factor for survival of patients with digestive system cancer. Furthermore, its overexpression is associated with TNM stage and pathological grade in digestive system cancer.

    Tumors located in the upper/upper inner quadrant of the breast warrant more attention. A small lesion relative to the size of breast in this location may be resolved by performing a level I oncoplastic technique. However, a wide excision may significantly reduce the overall quality of the breast shape by distorting the visible breast line. From June 2012 to April 2015, 36 patients with breast cancer located in the upper/upper inner quadrant underwent breast-conservation surgery with matrix rotation mammoplasty. According to the size and location of the tumor relative to the nipple-areola complex, 11 patients underwent matrix rotation with periareolar de-epithelialization (donut group) and the other 25 underwent matrix rotation only (non-donut group). The cosmetic results were self-assessed by questionnaires. The average weights of the excised breast lumps in the donut and non-donut groups were 104.1 and 84.5 g, respectively. During the 3-year follow-up period, local recurrence was observed in one case and was managed with nipple-sparing mastectomy followed by breast reconstruction with prosthetic implants. In total, 31 patients (88.6%) ranked their postoperative result as either acceptable or satisfactory. The treated breasts were also self-evaluated by 27 patients (77.1%) to be nearly identical to or just slightly different from the untreated side. Matrix rotation is an easy breast-preserving technique for treating breast cancer located in the upper/upper inner quadrant of the breast that requires a relatively wide excision. With this technique, a larger breast tumor could be removed without compromising the breast appearance.

    Esophageal cancer represents the sixth most common cause of the death caused by malignant diseases. The incidence is 11.5/100 000 in men population and 4.7/100 000 in women. It is the eighth most common malignancy. The incidence grows up, it doubled in Slovakia in last period and 5-year survival is only 18 %. Esophagectomy is a huge burden for organism. Mortality varies from 8.1 % to 23 % in low-volume departments in comparison with high-volume centres, where it is lower then 5 %. Complications range after operations is 30 – 80 %. Minimally invasive approach leads to the reduction of mortality and morbidity according to lot of studies. We performed 121 esophagectomies in cancer in period 2010 – 2015 and in 2015 it was 32 operations. We performed 29 totally minimally invasive esophagectomies, 16 hybrid MIE and 66 open esophagectomies. The chylothorax occurs twice, we managed it by surgery. The anastomotic dehiscence represents 9.09 %. Cardiovascular system complications occur in 43 %, need for vasopressors caused by hypotensia was in 44 %. It concluded from that we started with restrictive management of patients during the operation and need for vasopressors last only for two days after the operation and did not cause renal failure or any other complications.30 days mortality was related to MODS evolved by sepsis caused by pneumonia, most common in cirrhotic patients in very poor condition. Tracheoneoesophageal fistula occur in three patients, they all underwent operation, one of them died because of severe pneumonia. We recorded grow number of patient in our institution, which is probably related to better cooperation with gastroenterologists all over Slovakia. (author)

    Full Text Available Background: Breast surgery compromises one of the most common cancer surgeries in females and commonly followed by acute postoperative pain. Pregabalin and ketamine have been used in many previous studies and was found to have a good analgesic profile. We assumed that pregabalin and ketamine can be used in control of postoperative pain in female patients undergoing breast cancer surgery. Material and Methods: Ninety female patients scheduled for cancer breast surgery were allocated in three groups (30 patients each, control group (group c received preoperative placebo, pregabalin group (group p received oral 150 mg pregabalin 1 h before surgery, ketamine group (group k received intravenous (IV 0.5 mg/kg ketamine with induction of anesthesia followed by 0.25 mg/kg/h IV throughout the surgery. All patients received general anesthesia and after recovery, the three groups were assessed in the first postoperative 24 h for postoperative visual analog scale (VAS , total 24 h morphine consumption, incidence of postoperative nausea and vomiting (PONV, sedation score >2 and any complications from the drugs used in the study. Results: The use of pregabalin or ketamine was found to reduce total postoperative morphine consumption with P 2. Conclusion: The use of preoperative oral 150 mg pregabalin 1 h before surgery or IV 0.5 mg ketamine with induction of anesthesia can reduce postoperative opioid consumption in breast cancer surgery without change in sedation or PONV and with a good safety profile.

    Full Text Available The incidence of anastomotic recurrence after curative resection of colorectal cancer is relatively low compared to that of other types of recurrence, such as hepatic, lung and local recurrence. However, almost all cases of anastomotic recurrence of colorectal cancer occur within 3 years after surgery. We experienced a rare case of anastomotic recurrence in whom colonoscopy revealed no signs of recurrence 3 years after surgery; however, anastomotic recurrence was detected over 5 years after surgery. A 60-year-old female with a history of surgery for cancer of the cecum in her forties underwent sigmoidectomy and right colectomy with D3 lymph node dissection for both stage IIA sigmoid colon cancer and stage IIA transverse colon cancer. Computed tomography and colonoscopy revealed no signs of recurrence 3 years after surgery; however, 5 years and 4 months after surgery, colonoscopy demonstrated surrounding flaring and swelling in the anastomotic area of the sigmoid colon, and a biopsy revealed an adenocarcinoma. Under the diagnosis of anastomotic recurrence over 5 years after surgery, lower anterior resection was performed. The patient has exhibited no other signs of recurrence in the 2 years since the last operation.

    Beyond age and comorbidity, functionality can shape the long-term survival potential of patients with cancer. Accordingly, herein the authors compared mortality and receipt of cancer-directed surgery according to patient function among older adults with kidney cancer. Using Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 2000 through 2009, the authors studied 28,326 elderly subjects with primary kidney cancer. Patient function was quantified using function-related indicators, claims indicative of dysfunction and disability. Adjusting for patient and cancer characteristics, competing risk regression was used to assess the relationship between function-related indicator count and cause-specific mortality and then generalized estimating equations were used to quantify the probability of surgery. A total of 13,619 adult patients (48.1%) with at least 1 function-related indicator were identified. A higher indicator category was associated with older age, greater comorbidity, female sex, unmarried status, lower socioeconomic status, and higher stage of disease (Pkidney cancer mortality varied minimally with patient function. Patients with ≥ 2 indicators received cancer-directed surgery less often than those without disability (odds ratio, 0.61; 95% CI, 0.56-0.66), although treatment probabilities remained high for patients with locoregional disease and low for those with metastatic cancer. Among older adults with kidney cancer, functional health stands as a significant predictor of long-term survival. However, receipt of cancer-directed surgery appears largely determined by cancer stage. Patient function should be considered more heavily when determining treatment for older adults with kidney cancer.

    Pancreatic ductal carcinoma is one of the most dismal malignancies of the gastrointestinal system. Even after curative resection, the actual 5-year survival is only 10%-20%. Of all the treatments used against pancreatic cancer, surgery is still the only one that can achieve complete cure. Pancreatic cancer spreads easily to the adjacent tissues and distant metastasis is common. Typically, this cancer invades the retropancreatic neural tissue, duodenum, portal vein (PV), and superior mesenteric vein (SMV), or regional lymph nodes. For this reason, aggressive surgery that removes the cancerous lesion completely is recommended. Several retrospective and prospective studies have been conducted to validate the usefulness of aggressive surgery for pancreatic cancer in the past few decades. Surprisingly, the survival benefits of aggressive surgery have been denied by most randomized controlled trials (RCTs). This implies that surgery alone is not enough. Thus, adjuvant therapy, such as radiotherapy and chemotherapy, has been given in combination with surgery to improve survival. Although the benefits of radiotherapy alone are limited, the results of chemotherapy are promising. Other newly evolving molecular targeting drugs may also improve the treatment outcomes of pancreatic cancer. (author)

    Published studies on laparoscopic surgery for transverse colon cancer are scarce. More studies are necessary to evaluate the feasibility, safety, and long-term oncologic outcomes of laparoscopic surgery for transverse colon cancer. From April 1996 to December 2010, 102 consecutive patients with stage II or III disease who had undergone curative resection for transverse colon cancer were enrolled. Seventy-nine patients underwent laparoscopy-assisted colectomy (LAC), whereas 23 patients underwent conventional open colectomy (OC). Short- and long-term outcomes of the two groups were compared. The OC group had a larger tumor size (7.6 ± 3.4 cm versus 5.2 ± 2.3 cm, P = .004) and more retrieved lymph nodes (26.4 ± 11.6 versus 17.5 ± 9.4, P = .002), without differences in resection margins. In the LAC group, return to diet was faster (4.5 ± 1.2 days versus 5.4 ± 1.8 days, P = .013), and postoperative hospital stay was shorter (12.1 ± 4.2 days versus 15.9 ± 4.8 days, P = .000). There were no differences in occurrence of intra- or postoperative complications. There were no statistically significant differences in overall survival rate (OS) or disease-free survival rate (DFS) between the two groups (5-year OS, 90.4% versus 90.5%, P = .670; 5-year DFS, 84.2% versus 90.7%, P = .463). Laparoscopic surgery for transverse colon cancer has better short-term outcomes compared with open surgery, with acceptable long-term outcomes. As in colorectal cancer of other sites, laparoscopic surgery can be a feasible alternative to conventional surgery for transverse colon cancer.

    Kyphoplasty surgery is widely used for pain relief in patients with vertebral compression fracture (VCF). For this surgery, an X-ray emitter that provides real-time imaging is employed to guide the medical instruments and the surgical cement used to fill and strengthen the vertebra. Equivalent and effective doses related to high temporal resolution equipment has been studied to assess the damage and more recently cancer risk. For this study, a virtual scenario was prepared using MCNPX code and a pair of UF family simulators. Two projections with seven tube voltages for each one were simulated. The organ in the abdominal region were those who had higher cancer risk because they receive the primary beam. The risk of lethal cancer is on average 20% higher in AP projection than in LL projection. This study aims at estimating the risk of cancer in organs and the risk of lethal cancer for patient submitted to kyphoplasty surgery.

    The Ser326Cys polymorphism in the human 8-oxogunaine DNA glycosylase (hOGG1) gene had been implicated in cancer susceptibility. Studies investigating the associations between the Ser326Cys polymorphism and digestion cancer susceptibility showed conflicting results. Therefore, a meta-analysis was performed to derive a more precise estimation of the relationship. We conducted a meta-analysis of 48 studies that included 12,073 cancer cases and 19,557 case-free controls. We assessed the strength of the association using odds ratios (ORs) with 95% confidence intervals (CIs). In our analysis, the hOGG1 Ser326Cys polymorphism was significantly associated with the risk of digestive system cancers (Cys/Cys vs. Ser/Ser: OR = 1.17, 95% CI = 1.00-1.35, P digestive cancers.

    Experimental and animal studies have supported the hypothesis that dipeptidyl peptidase-4 inhibitors (DPP-4i) may accelerate tumor metastasis. The aim was to analyze the relationships between DPP-4i therapy with risk of metastases in type 2 diabetes patients with breast, prostate and digestive organ cancers. Type 2 diabetes patients with first diagnoses of breast, prostate or digestive organ cancer were selected in general and internal medicine practices (Disease Analyzer Germany: 01/2008-12/2014). Propensity score matching between DPP-4i users and non-users was carried out for age, sex, diabetes duration, and metformin use. Time-dependent Cox regression models were used to estimate hazard ratios (HR) for metastases further adjusting for HbA1c, body mass index, comorbidity and co-therapy with glucose-lowering drugs (3-4years follow-up). 668 patients with newly diagnosed breast cancer, 906 with prostate cancer and 908 with digestive organ cancer were analyzed. In Cox regression, use of DPP-4i was not associated with an increased risk of metastases in patients with breast (adjusted HR, 95%CI: 1.00, 0.49-2.02), prostate (0.98, 0.54-1.77) or digestive organ cancers (0.97, 0.57-1.66). This first observational study in patients with type 2 diabetes and breast, prostate or digestive organ cancer found no increased risk of metastases in DPP-4i users. Copyright © 2017 Elsevier Inc.

    The long-term oncologic stability of laparoscopic surgery for colon cancer was established, and laparoscopic surgery was accepted as an alternative to conventional open surgery for colon cancer. However, transverse colon cancer was excluded from the majority of the previous prospective studies. As a result, debate on laparoscopic surgery for transverse colon cancer continues. This study aimed to compare the clinicopathologic outcome of laparoscopic surgery with that of conventional open surgery for transverse colon cancer. From August 2004 to December 2007, 106 cases of transverse colon cancer were managed by resection at our institution, and 89 of these cases were included in this study. Age, sex, body mass index (BMI), operation time, blood loss, time to first flatus, time to start of diet, hospital stay, complications, tumor size, distal resection margin, proximal resection margin, and number of nodes harvested were compared between the two groups. No significant differences were found between the laparoscopic and conventional groups in terms of age, sex, BMI, operation time, or hospital stay. The mean blood loss during the operations was significantly less in the laparoscopic group (113.8 +/- 128.9 ml) than in the conventional group (278.8 +/- 268.7 ml; p transverse colon cancer, and the oncologic quality of laparoscopic surgery was found to be acceptable compared with conventional open surgery.

    AIM To analyses the current literature regarding the urogenital functional outcomes of patients receiving robotic rectal cancer surgery. METHODS A comprehensive literature search of electronic databases was performed in October 2015. The following search terms were applied: 'rectal cancer' or 'colorectal cancer' and robot* or 'da Vinci' and sexual or urolog* or urinary or erect* or ejaculat* or impot* or incontinence. All original studies examining the urological and/or sexual outcomes of male and/or female patients receiving robotic rectal cancer surgery were included. Reference lists of all retrieved articles were manually searched for further relevant articles. Abstracts were independently searched by two authors. RESULTS Fifteen original studies fulfilled the inclusion criteria. A total of 1338 patients were included; 818 received robotic, 498 laparoscopic and 22 open rectal cancer surgery. Only 726(54%) patients had their urogenital function assessed via means of validated functional questionnaires. From the included studies, three found that robotic rectal cancer surgery leads to quicker recovery of male urological function and five of male sexual function as compared to laparoscopic surgery. It is unclear whether robotic surgery offers favourable urogenital outcomes in the long run for males. In female patients only two studies assessed urological and threesexual function independently to that of males. In these studies there was no difference identified between patients receiving robotic and laparoscopic rectal cancer surgery. However, in females the presented evidence was very limited making it impossible to draw any substantial conclusions. CONCLUSION There seems to be a trend towards earlier recovery of male urogenital function following robotic surgery. To evaluate this further, larger well designed studies are required.

    Purpose: Cancers of the digestive system constitute a major risk for childhood cancer survivors treated with radiotherapy once they reach adulthood. The aim of this study was to determine therapy-related risk factors for the development of a second malignancy in the digestive organs (SMDO) after a childhood cancer. Methods and Materials: Among 4,568 2-year survivors of a childhood solid cancer diagnosed before 17 years of age at eight French and British centers, and among 25,120 patients diagnosed as having a malignant neoplasm before the age of 20 years, whose data were extracted from the Nordic Cancer Registries, we matched 58 case patients (41 men and 17 women) of SMDO and 167 controls, in their respective cohort, for sex, age at first cancer, calendar year of occurrence of the first cancer, and duration of follow-up. The radiation dose received at the site of each second malignancy and at the corresponding site of its matched control was estimated. Results: The risk of developing a SMDO was 9.7-fold higher in relation to the general populations in France and the United Kingdom. In the case-control study, a strong dose–response relationship was estimated, compared with that in survivors who had not received radiotherapy; the odds ratio was 5.2 (95% CI, 1.7–16.0) for local radiation doses between 10 and 29 Gy and 9.6 (95% CI, 2.6–35.2) for doses equal to or greater than 30 Gy. Chemotherapy was also found to increase the risk of developing SMDO. Conclusions: This study confirms that childhood cancer treatments strongly increase the risk of SMDO, which occur only after a very long latency period.

    Full Text Available Purpose: The rapidly increasing burden of cancer in India has profound impacts on health care costs for patients and their families. High out-of-pocket (OOP expenditure, lack of insurance, and low government expenditure create a vicious cycle, leading to household impoverishment. Complex cancer surgery is now increasingly important for emerging countries; however, little is understood about the macro- and microeconomics of these procedures. After the Lancet Oncology Commission on Global Cancer Surgery, we evaluated the OOP expenditure for patients undergoing pancreatico-duodenectomy (PD at a government tertiary cancer center in India. Methods: Prospective data from 98 patients who underwent PD between January 2014 and June 2015 were collected and analyzed. The time frame for consideration of expenses, including all preoperative investigations, was from the first hospital visit to the day of discharge. Catastrophic expenditure was calculated by assessing the percentage of households in which OOP health payments exceeded 10% of the total household income. Results: The mean expenditure for PD by patients was Rs.295,679.57 (US$74,420, purchasing power parity corrected. This amount was significantly higher among those admitted to a private ward and those with complications. Only 29.6% of the patients had insurance coverage. A total of 76.5% of the sample incurred catastrophic expenditure, and 38% of those with insurance underwent financial catastrophe compared with 93% of those without insurance. The percentage of patients facing catastrophic impact was highest among those in semiprivate wards, at 86.7%, followed by those in public and private wards. Conclusion: The cost of PD is high and is often unaffordable for a majority of India’s population. A review of insurance coverage policies for better coverage must be considered.

    Although qualitative research that focuses on inpatients' experience immediately after surgery has continued to elucidate the efficacy of the nursing service for postoperative recovery, there has been little quantitative research. Our aim was to quantitatively clarify the association between inpatients' perception of the nursing service and the quality of postoperative recovery. Seventy-one digestive cancer patients who underwent surgery were recruited. Participants completed two self-administered questionnaires, including the Japanese version of the 40-item postoperative Quality of Recovery scale (QoR-40J) and the Nursing Service Quality Scale for Japan (NURSERV-J) which has 22 items and five dimensions (tangibles, reliability, responsiveness, assurance, and empathy) on postoperative day 3. There were significant positive associations between the global scores of the NURSERV-J and the QoR-40J. The global score of the QoR-40J was compared between patients who gave full marks for each dimension of the NURSERV-J (the entirely satisfied group) and those who did not (the not entirely satisfied group). The entirely satisfied groups regarding tangibles, reliability and responsiveness had a significantly higher global score for the QoR-40J than the respective not entirely satisfied groups. Adjusted for age, gender, operative procedure, and duration of surgery, the entirely satisfied groups regarding tangibles and responsiveness had a significant higher global score for the QoR-40J than the respective not entirely satisfied groups. Patients who perceived that they had received a nursing service of high quality were likely to attain a high quality of postoperative recovery. Nursing services related to tangibles, reliability, and responsiveness especially contributed to postoperative recovery.

    Objectives To determine functional status and mortality rates after colon cancer surgery in older nursing home residents. Design Retrospective cohort study. Setting and Participants 6822 nursing home residents age 65 and older who underwent surgery for colon cancer in the United States between 1999 and 2005. Measurements Changes in functional status were assessed before and after surgery using the Minimum Data Set-Activities of Daily Living (MDS-ADL) summary scale, a 28-point scale in which score increases as functional dependence increases. Methods Using the Medicare Inpatient File and the Minimum Data Set for Nursing Homes, we identified the 6822 nursing home residents age 65 and older who underwent surgery for colon cancer. We used regression techniques to identify patient characteristics associated with mortality and functional decline at 1 year after surgery. Results On average, residents who underwent colectomy experienced a 3.9 point worsening in MDS-ADL score at one year. One year after surgery, the rates of mortality and sustained functional decline were 53% and 24%, respectively. In multivariate analysis, older age (age 80+ v. age 65–69, adjusted relative risk (ARR 1.53), 95%CI 1.15–2.04, pppp<0.0001) were associated with functional decline at one year. Conclusion Mortality and sustained functional decline are very common after colon cancer surgery in nursing home residents. Initiatives aimed at improving surgical outcomes are needed in this vulnerable population. PMID:22428583

    Advanced age, pelvic surgery, and the presence of malignancy place gynecologic oncology patients at high risk for venous thromboembolism (VTE). This study was designed to systematically analyze the world's literature on VTE in these patients and determine the optimal prophylaxis regimen. Computerized searches of Pubmed, Ovid, DARE, ACP Journal Club, Cochrane Database of Systematic Reviews, and Cochrane Controlled Trials Registry 1966-2005 were performed, as well as EMBASE 1980-2005. Major conferences and target references were hand-searched. Inclusion criteria were randomized controlled trials (RCTs) evaluating VTE prophylaxis with heparin, low-molecular-weight heparin (LMWH), and sequential compression devices (SCD). The search yielded 278 articles; 11 met inclusion criteria. Data were abstracted by one author and analyzed with the Mantel-Haenszel method. The analysis of heparin-versus-control revealed a significant decrease in DVT in patients receiving heparin (RR=0.58, 95% CI 0.35-0.95). There were no significant differences in EBL or transfusions between the two groups. In the 320 patients in the heparin vs. LMWH studies, there was no significant difference in DVT (RR 0.91, 95% CI 0.38-2.17), although power analysis demonstrated insufficient numbers to show a difference. No patient in either group required re-exploration for bleeding. All gynecologic cancer patients should receive VTE prophylaxis. Although heparin, LMWH, and SCD have been shown to be safe and effective, due to the paucity of data in the gynecologic oncology literature, no one prevention modality can be considered superior at this time. Adequately powered RCTs are urgently needed to determine the optimal regimen in these high-risk patients.

  9. Results of conservative surgery and radiation therapy for breast cancer

    For stage I or II breast cancer, conservative surgery and radiation therapy are as effective as modified radical or radical mastectomy. In most cases, cosmetic considerations and the availability of therapy are the primary concerns. The extent of a surgical resection less than a mastectomy has not been a subject of a randomized trial and is controversial. It appears that removal of a quadrant of the breast for small lesions is safe but excessive. It may be possible to limit the breast resection to gross tumor removal for most patients while using wider resections for patients with an extensive intraductal component or for invasive lobular carcinoma. It also appears that excluding patients from breast conservation on the basis of positive margins on the first attempt at tumor excision may be unnecessarily restrictive. Although patients with an extensive intraductal component or invasive lobular carcinoma should have negative margins, it appears that a patient with predominantly invasive ductal carcinoma can be treated without re-excision if all gross tumor has been resected and there is no reason to suspect extensive microscopic disease. Patients with indeterminate margins should have a re-excision. Axillary dissection provides prognostic information and prevents progression of the disease within the axilla. Axillary dissections limited to level I will accurately identify a substantial number of patients who have pathologically positive but clinically negative nodes. When combined with radiation therapy to the axilla, a level I dissection results in a limited number of patients with progressive axillary disease. Patients with pathologically positive axillas and patients at particularly high risk for systemic disease because of the extent of axillary node involvement can be identified by dissections of levels I and II. 60 references.

    The risk of metachronous colorectal cancer is high after surgical resection for first colon cancer in Lynch syndrome. This study aimed to examine whether extended surgery decreases the risk of subsequent colorectal cancer and improves long-term survival. This was a retrospective study. Data were collected from a nationwide registry. Two hundred forty-two Lynch syndrome pathogenic variant carriers who underwent surgery for a first colon cancer from 1984 to 2009 were included. Patients underwent standard segmental colectomy (n = 144) or extended colectomy (n = 98) for colon cancer. Patients were followed a median of 14.6 up to 25 years. Risk of subsequent colorectal cancer in either group, overall and disease-specific survival, and operative mortality were the primary outcomes measured. Subtotal colectomy decreased the risk of subsequent colorectal cancer (HR, 0.20; 95% CI, 0.08-0.52; p = 0.001), compared with segmental resection. Subsequent colorectal cancer decreased in MLH1 carriers. The MSH2 carriers showed no statistical difference, possibly because of their small number. Disease-specific and overall survival within 25 years did not differ between the standard and extended surgeries (82.7% vs 87.2%, p = 0.76 and 47.2% vs 41.4%, p = 0.83). The cumulative risk of subsequent colorectal cancer was 20% in 10 years and 47% within 25 years after standard resection and 4% and 9% after extended surgery. The cumulative risk of metachronous colorectal cancer was 7% within 25 years after subtotal colectomy with ileosigmoidal anastomosis. One patient died of postoperative septicemia within 30 days after segmental colectomy. Data on surgical procedures were primarily collected retrospectively. Lynch syndrome pathogenic variant carriers may undergo subtotal colectomy to manage first colon cancer and avoid repetitive abdominal surgery and to reduce the remaining bowel to facilitate easier endoscopic surveillance. It provides no survival benefit, compared with segmental colon

    Breast cancer is the leading oncological cause of death in Mexican women over 25 years old. Given the need to improve postoperative cosmetic results in patients with breast cancer, oncoplastic surgery has been developed, which allows larger tumour resections and minor cosmetic alterations. To determine the oncological feasibility and cosmetic outcome of oncoplastic surgery at the Instituto de Enfermedades de la Mama, FUCAM, AC. A review was conducted from January 2010 to July 2013, which included patients with breast cancer diagnosis treated with conventional breast-conserving surgery or with oncoplastic surgery in the Institute of Diseases of the Breast, FUCAM AC. Clinical and histopathological parameters were compared between the two groups, and a questionnaire of cosmetic satisfaction and quality of life was applied. Of the 171 patients included, 95 of them were treated with conventional breast-conserving surgery and 76 with oncoplastic surgery. Pathological tumour size was significantly larger in patients treated with oncoplastic surgery (p = 0.002). There were no differences found between the groups as regards the number of patients with positive surgical margin, the rate of complications, and cosmetic satisfaction. This study demonstrates the oncological feasibility and high cosmetic satisfaction of oncoplastic surgery with minimal psycho-social impact on patients.

    Breast conservative surgery after neoadjuvant chemotherapy intends to remove any residual tumor with negative margins. The purpose of this study was to analyze the preoperative clinical-pathological factors influencing the margin status after conservative surgery in breast cancer patients receiving neoadjuvant chemotherapy. A retrospective study of 91 breast cancer patients undergoing neoadjuvant chemotherapy (92 breast lesions) during the period 2006 to 2013. A Cox regression analysis to identify baseline tumor characteristics associated with positive margins after breast conservative surgery was performed. Of all cases, 71 tumors were initially treated with conservative surgery after neoadjuvant chemotherapy. Pathologic exam revealed positive margins in 16 of the 71 cases (22.5%). The incidence of positive margins was significantly higher in cancers with initial size >5cm (P=.021), in cancers with low tumor grade (P=.031), and in patients with hormone receptor-positive cancer (P=.006). After a median follow-up of 45.2 months, 7 patients of the 71 treated with conservative surgery had disease recurrence (9.8%). There was no significant difference in terms of disease-free survival according to the margin status (P=.596). A baseline tumor size >5cm, low tumor grade and hormone receptor-positive status increase the risk for surgical margin involvement in breast conservative surgery after neoadjuvant chemotherapy.

    Although pre-operative chemoradiation therapy for advanced lower rectal cancer is a controversial treatment modality, it is increasingly used in combination with surgery. Few studies have considered the combination of chemoradiation therapy followed by laparoscopic surgery for locally advanced lower rectal cancer; therefore, this study aimed to assess the usefulness of this therapeutic combination. We retrospectively reviewed the medical records of patients with locally advanced lower rectal cancer treated by pre-operative chemoradiation therapy and surgery from February 2002 to November 2012 at Oita University. We divided patients into an open surgery group and a laparoscopic surgery group and evaluated various parameters by univariate and multivariate analyses. In total, 33 patients were enrolled (open surgery group, n=14; laparoscopic surgery group, n=19). Univariate analysis revealed that compared with the open surgery group, operative time was significantly longer, whereas intra-operative blood loss and intra-operative blood transfusion requirements were significantly less in the laparoscopic surgery group. There were no significant differences in post-operative complication and recurrence rates between the two groups. According to multivariate analysis, operative time and intra-operative blood loss were significant predictors of outcome in the laparoscopic surgery group. This study suggests that laparoscopic surgery after chemoradiation therapy for locally advanced lower rectal cancer is a safe procedure. Further prospective investigation of the long-term oncological outcomes of laparoscopic surgery after chemoradiation therapy for locally advanced lower rectal cancer is required to confirm the advantages of laparoscopic surgery over open surgery.

    The angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism has been reported to be associated with digestive system cancer; however, the results from previous studies have been conflicting. The present study aimed to investigate the association between the ACE I/D polymorphism and the risk of digestive system cancer using a meta-analysis of previously published studies. Databases were systematically searched to identify relevant studies published prior to December 2014. We estimated the pooled OR with its 95%CI to assess the association. The meta-analysis consisted of thirteen case-control studies that included 2557 patients and 4356 healthy controls. Meta-analysis results based on all the studies showed no significant association between the ACE I/D polymorphism and the risk of digestive system cancer (DD vs II: OR = 0.85, 95%CI = 0.59-1.24; DI vs II: OR = 0.94, 95%CI = 0.78-1.15; dominant model: OR = 0.96, 95%CI = 0.81- 1.15; recessive model: OR = 1.06, 95%CI = 0.76-1.48). Subgroup analyses by race and cancer type did not detect an association between the ACE I/D polymorphism and digestive system cancer risk. However, when the analyses were restricted to smaller studies (N digestive system cancer. Further large and well-designed studies are needed to confirm these conclusions.

    To compare all-cause mortality between women who underwent fertility-sparing surgery with those who underwent conventional surgery for stage I ovarian cancer. In a cohort study using the National Cancer Database, we identified women younger than 40 years diagnosed with stage IA and unilateral IC epithelial ovarian cancer between 2004 and 2012. Fertility-sparing surgery was defined as conservation of one ovary and the uterus. The primary outcome was time from diagnosis to death. We used propensity score methods to assemble a cohort of women who underwent fertility-sparing or conventional surgery but were otherwise similar on observed covariates and conducted survival analyses using the Kaplan-Meier method and Cox proportional hazard models. We identified 1,726 women with stage IA and unilateral IC epithelial ovarian cancer of whom 825 (47.8%) underwent fertility-sparing surgery. Fertility-sparing surgery was associated with younger age, residence in the northeastern and western United States, and serous or mucinous histology (Pfertility-sparing surgery and 37 deaths among propensity-matched women who underwent conventional surgery after a median follow-up of 63 months. Fertility-sparing surgery was not associated with hazard of death (hazard ratio 0.80, 95% confidence interval [CI] 0.49-1.29, P=.36). The probability of survival 10 years after diagnosis was 88.5% (95% CI 82.4-92.6) in the fertility-sparing group and 88.9% (95% CI 84.9-92.0) in the conventional surgery group. In patients with high-risk features such as clear cell histology, grade 3, or stage IC, 10-year survival was 80.5% (95% CI 68.5-88.3) among women who underwent fertility-sparing surgery and 83.4% (95% 76.0-88.7) among those who had conventional surgery (hazard ratio 0.86, 95% CI 0.49-1.53, P=.61). Compared with conventional surgery, fertility-sparing surgery was not associated with increased risk of death in young women with stage I epithelial ovarian cancer.

    Locally advanced lung cancer has a poor prognosis, despite extensive surgery conducted in an effort to improve survival. We evaluated the safety and efficacy of induction therapy prior to extensive surgery for locally advanced lung cancer. Primary resection for lung cancer was done in 549 consecutive patients divided into three groups; 446 undergoing standard pulmonary resection (no extensive surgery), 87 undergoing extensive surgery without induction therapy, and 16 undergoing surgery after induction therapy. Morbidity was 23.5%, 28.6%, and 43.8%, respectively. The rate was significantly higher in the induction group compared with the no extensive surgery group (P<0.05). Surgical mortality was 0.67%, 3.4%, and 6.3%, respectively. The difference was statistically significant between the no extensive surgery and extensive surgery groups (P<0.02), and between the no extensive surgery and induction groups (P<0.02). Hospital mortality was 2.2%, 9.2%, and 6.3%, respectively. The rates were significantly higher in the extensive surgery (P<0.01) and induction (P<0.05) groups compared to the no extensive surgery group. Five-year survival was 50.3% for the patients who received induction therapy, and 14.7% for the patients who did not receive induction therapy. Survival differences between the induction and non induction groups were not significant, but some patients with T3 or T4 disease may benefit from induction therapy. The high morbidity of induction treatment should be recognized, and strict candidate selection and careful postoperative care used to help prevent increased mortality. (author)

    AIM: Both the Danish and the National Institute of Clinical Excellence (NICE) guidelines recommend prolonged thromboprophylaxis (PT) with low-molecular-weight heparin (LMWH) for 28 days postoperatively after elective surgery for colon cancer. The evidence relies on data from two randomized clinical...... trials (RCTs) that included not only colon cancers but also other abdominal cancers or benign colorectal diseases. Neither of those studies investigated the risk of venous thromboembolism (VTE) under enhanced recovery after surgery (ERAS). We aim to describe the risk of VTE and estimate the cost...... of preventing one case of VTE by PT under ERAS. METHOD: This was a retrospective study of 2230 patients undergoing elective surgery for colon cancer Stage I-III in the Capital Region of Denmark, 1 June 2008 to 31 December 2013. Patients who were discharged on postoperative day 28 or later, died during admission...

    The definite prognostic role of p-STAT3 has not been well defined. We performed a meta-analysis evaluating the prognostic role of p-STAT3 expression in patients with digestive system cancers. We searched the available articles reporting the prognostic value of p-STAT3 in patients with cancers of the digestive system, mainly including colorectal cancer, gastric cancer, hepatocellular carcinoma, esophagus cancer and pancreatic cancer. The pooled hazard ratios (HRs) with 95 % confidence intervals (95 % CIs) of overall survival (OS) and disease-free survival (DFS) were used to assess the prognostic role of p-STAT3 expression level in cancer tissues. And the association between p-STAT3 expression and clinicopathological characteristics was evaluated. A total of 22 studies with 3585 patients were finally enrolled in the meta-analysis. The results showed that elevated p-STAT3 expression level predicted inferior OS (HR = 1.809, 95% CI: 1.442-2.270, P digestive system. Increased expression of p-STAT3 is significantly related with tumor cell differentiation (Odds ratio (OR) = 1.895, 95% CI: 1.364-2.632, P digestive system cancers. More well designed studies with adequate follow-up are needed to gain a thorough understanding of the prognostic role of p-STAT3.

    Patients with rectal cancer have issues in adjusting to their permanent colostomy after surgery, and support is required to help them resume normal life. However, few studies have explored the experience and factors that affect a patient's decision-making and maladjustment prior to colostomy surgery. The aim of this study was to explore the experience of rectal cancer patients who have to undergo colostomy surgery. A descriptive, qualitative design was used. We studied a purposive sample of 18 patients who had received a diagnosis of primary rectal cancer and were expecting permanent colostomy surgery. The thematic analysis approach was used to analyze the data collected using semi-structured, open-ended questions. The overriding theme that emerged was 'stoma dilemma: a hard decision-making process'. From this main theme, three themes were derived: the resistance stage, the hesitation stage, and the acquiescence stage. It is hard for preoperative rectal patients to choose to undergo stoma surgery or a sphincter-saving operation. From the initial stage of definitive diagnosis to the final consent to stoma surgery, most patients experience the resistance and hesitation stages before reaching the acquiescence stage. Arriving at a decision is a process that nurses can facilitate by eliminating unnecessary misunderstanding surrounding colostomy surgery and by fully respecting patients' right to choose at the various stages.

    AIM To analyses the current literature regarding the urogenital functional outcomes of patients receiving robotic rectal cancer surgery.METHODS A comprehensive literature search of electronic databases was performed in October 2015. The following search terms were applied: “rectal cancer” or “colorectal cancer” and robot* or “da Vinci” and sexual or urolog* or urinary or erect* or ejaculat* or impot* or incontinence.All original studies examining the urological and/or sexual outcomes of male and/or female patients receiving robotic rectal cancer surgery were included. Reference lists of all retrieved articles were manually searched for further relevant articles. Abstracts were independently searched by two authors.RESULTS Fifteen original studies fulfilled the inclusion criteria.A total of 1338 patients were included; 818 received robotic, 498 laparoscopic and 22 open rectal cancer surgery. Only 726 (54%) patients had their urogenital function assessed via means of validated functional questionnaires. From the included studies, three found that robotic rectal cancer surgery leads to quicker recovery of male urological function and five of male sexual function as compared to laparoscopic surgery.It is unclear whether robotic surgery offers favourable urogenital outcomes in the long run for males. In female patients only two studies assessed urological and three sexual function independently to that of males. In these studies there was no difference identified between patients receiving robotic and laparoscopic rectal cancer surgery. However, in females the presented evidence was very limited making it impossible to draw any substantial conclusions.CONCLUSION There seems to be a trend towards earlier recovery of male urogenital function following robotic surgery. To evaluate this further, larger well designed studies are required.

    There is merging evidence suggesting that the miR-146a polymorphism might be associated with susceptibility to digestive system cancer. However, previous published studies have failed to achieve a definitive conclusion. To address this issue, an updated meta-analysis was performed. A comprehensive electronic search was conducted using the following source to identify the eligible studies: PubMed, Embase, China BioMedicine, the Cochrane Library, and Google Scholar. Odds ratios and its corresponding 95% confidence interval (CI) was used in the quantitative synthesis. The database search identified 1344 eligible studies, of which 32 (comprising 12,541 cases and 15,925 controls) were included. The results indicate that the miR-146a rs2910164 polymorphism was significantly associated with increased risk of digestive system cancer in heterozygote comparison (GC vs. CC: OR=1.15, 95% CI: 1.02-1.30, P=0.02), and recessive model (GG vs. GC+CC: OR=1.11, 95% CI: 1.04-1.17, P=0.006). Subgroup analysis by cancer site revealed increased risk in gastric cancer above heterozygote comparison (GG vs. GC: OR=1.13, 95% CI: 1.02-1.25, P=0.02), and recessive model (GG vs. GC+CC: OR=1.15, 95% CI: 1.04-1.26, P=0.006). Similarly, increased cancer risk was observed in hepatocellular carcinoma when compared with homozygote comparison (GG vs. CC: OR=1.21, 95% CI: 1.04-1.42, P=0.02), heterozygote comparison (GC vs. CC: OR=1.15, 95% CI: 1.02-1.29, P=0.02), and dominant model (GG+GC vs. CC: OR=1.16, 95% CI: 1.04-1.29, P=0.009). When stratified by ethnicity and quality score, increased cancer risks were also observed among Asians, Caucasians and high quality studies subgroup. The current study revealed that miR-146a G/C genetic polymorphism was more likely to be associated with digestive system cancer risk. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Previous studies have shown that laparoscopic colorectal cancer surgery is highly safe and effective compared to laparotomy. However, whether laparoscopic colorectal cancer surgery can be safely performed in patients with severe comorbidities remains unclear. The aim of this study was to evaluate the safety of laparoscopic colorectal cancer surgery in patients with severe comorbidities. A total of 82 consecutive patients with colorectal cancer who underwent laparoscopic surgery were retrospectively divided into two groups according to whether they had severe comorbidity (50 patients) or non-severe comorbidity (32 patients). An age-adjusted Charlson comorbidity index of ≥6 was defined as severe comorbidity. Operative time, blood loss, and rate of conversion to laparotomy did not differ between the groups. Postoperative complications and the length of the postoperative hospital stay also did not differ significantly between the groups. Laparoscopic colorectal cancer surgery is feasible and safe, even in patients with severe comorbidities. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

    Breast cancer patients commonly use the internet as an information resource. Our objective was to evaluate the quality of online information available to support patients facing a decision for breast surgery. Breast cancer surgery-related queries were performed (Google and Bing), and reviewed for content pertinent to breast cancer surgery. The DISCERN instrument was used to evaluate websites' structural components that influence publication reliability and ability of information to support treatment decision-making. Scores of 4/5 were considered "good." 45 unique websites were identified. Websites satisfied a median 5/9 content questions. Commonly omitted topics included: having a choice between breast conservation and mastectomy (67%) and potential for 2nd surgery to obtain negative margins after breast conservation (60%). Websites had a median DISCERN score of 2.9 (range 2.0-4.5). Websites achieved higher scores on structural criteria (median 3.6 [2.1-4.7]), with 24% rated as "good." Scores on supporting decision-making questions were lower (2.6 [1.3-4.4]), with only 7% scoring "good." Although numerous breast cancer-related websites exist, most do a poor job providing women with essential information necessary to actively participate in decision-making for breast cancer surgery. Providing easily- accessible, high-quality online information has the potential to significantly improve patients' experiences with decision-making. © 2015 Wiley Periodicals, Inc.

  13. Emerging and established global life-style risk factors for cancer of the upper aero-digestive tract.

    Gupta, Bhawna; Johnson, Newell W

    2014-01-01

    Upper aero-digestive tract cancer is a multidimensional problem, international trends showing complex rises and falls in incidence and mortality across the globe, with variation across different cultural and socio-economic groups. This paper seeks some explanations and identifies some research and policy needs. The literature illustrates the multifactorial nature of carcinogenesis. At the cellular level, it is viewed as a multistep process involving multiple mutations and selection for cells with progressively increasing capacity for proliferation, survival, invasion, and metastasis. Established and emerging risk factors, in addition to changes in incidence and prevalence of cancers of the upper aero-digestive tract, were identified. Exposure to tobacco and alcohol, as well as diets inadequate in fresh fruits and vegetables, remain the major risk factors, with persistent infection by particular so-called "high risk" genotypes of human papillomavirus increasingly recognised as also playing an important role in a subset of cases, particularly for the oropharynx. Chronic trauma to oral mucosa from poor restorations and prostheses, in addition to poor oral hygiene with a consequent heavy microbial load in the mouth, are also emerging as significant risk factors. Understanding and quantifying the impact of individual risk factors for these cancers is vital for health decision-making, planning and prevention. National policies and programmes should be designed and implemented to control exposure to environmental risks, by legislation if necessary, and to raise awareness so that people are provided with the information and support they need to adopt healthy lifestyles.

    Video-assisted thoracic surgery (VATS) emerged as a minimally invasive surgery for diseases in the field of thoracic surgery. We herein reviewed our experience on thoracoscopic lobectomy for early lung cancer and evaluated Health System use. A cost-effectiveness study was performed comparing VATS vs. open thoracic surgery (OPEN) for lung cancer patients. Demographic data, tumor localization, dynamic pulmonary function tests [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), diffusion capacity (DLCO) and maximal oxygen uptake (VO2max)], surgical approach, postoperative details, and complications were recorded and analyzed. One hundred seventeen patients underwent lung resection by VATS (n=42, 36%; age: 63±9 years old, 57% males) or OPEN (n=75, 64%; age: 61±11 years old, 73% males). Pulmonary function tests decreased just after surgery with a parallel increasing tendency during first 12 months. VATS group tended to recover FEV1 and FVC quicker with significantly less clinical and post-surgical complications (31% vs. 53%, P=0.015). Costs including surgery and associated hospital stay, complications and costs in the 12 months after surgery were significantly lower for VATS (P<0.05). The VATS approach surgery allowed earlier recovery at a lower cost than OPEN with a better cost-effectiveness profile.

    To assess the risk of occurrence of port-site metastases after robotic surgery for pelvic cancer. Retrospective study from June 2007 to March 2013 of patients with gynecologic cancer who underwent robot-assisted surgery. We collected preoperative data, including characteristics of patients and FIGO stage, intraoperative data (surgery performed, number of ports), and postoperative data (occurrence of metastases, occurrence of port-site metastases). 115 patients were included in the study: 61 with endometrial cancer, 50 with cervical cancer and 4 with ovarian cancer. The surgical procedures performed were: hysterectomy with bilateral salpingo-oophorectomy, radical hysterectomy, pelvic lymphadenectomy, para-aortic lymphadenectomy and omentectomy. All surgical procedures required the introduction of 4 ports, 3 for the robot and 1 for the assistant. With a mean follow-up of 504.4 days (507.7 days for endometrial cancer, 479.5 days for cervical cancer, and 511.3 for ovarian cancer), we observed 9 recurrences but no port-site metastasis. No port-site metastasis has occurred in our series. However, larger, prospective and randomized works are needed to formally conclude. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Chronic pancreatitis is suggested to be one of the risk factors for the development of pancreatic cancer. The aim of this study was to confirm the high incidence of pancreatic cancer in patients with chronic pancreatitis in Japan and to determine the factors associated with the risk for pancreatic cancer in patients with chronic pancreatitis. The working group of the Research Committee of Intractable Disease supported by the Ministry of Health, Labour and Welfare of Japan carried out a nationwide survey to investigate the relationship between chronic pancreatitis and pancreatic cancer. This retrospective study included patients diagnosed with chronic pancreatitis who had had at least 2 years of follow-up. They were contacted through 22 Japanese referral centers experienced in the management of chronic pancreatitis. The standardized incidence ratio (95 CI) of pancreatic cancer was 11.8 (7.1-18.4). The incidence of pancreatic cancer was significantly lower in patients who had received surgery for chronic pancreatitis than in those who had not undergone surgery (hazard ratio estimated by Cox regression 0.11; 95% CI, 0.0014-0.80; P = .03). Patients who continued to drink alcohol after diagnosis of chronic pancreatitis showed a significantly higher incidence of pancreatic cancer than those who stopped drinking after diagnosis of chronic pancreatitis (hazard ratio, 5.07; 95% CI, 1.13-22.73; P = .03). This study confirmed that chronic pancreatitis is an important risk factor for the development of pancreatic cancer in Japan. Patients who underwent surgery for the treatment of chronic pancreatitis had significantly lower incidences of pancreatic cancer. Surgery for chronic pancreatitis may inhibit the development of pancreatic cancer in patients with chronic pancreatitis. Copyright © 2013 Mosby, Inc. All rights reserved.

    A D2 lymphadenectomy can be considered standard of surgical care for advanced resectable gastric cancer. Currently, several multimodality strategies are used, including postoperative monochemotherapy in Asia, postoperative chemoradiotherapy in the United States, and perioperative chemotherapy in Europe. As the majority of gastric cancer patients are treated outside the framework of clinical trials, quality assurance programs, including referral to high-volume centers and clinical auditing are needed to improve gastric cancer care on a nationwide level.

    Residents in our country have achieved a homogenous surgical training by following a structured residency program. This is due to the existence of specific training programs for each specialty. The current program, approved in 2007, has a detailed list of procedures that a surgeon should have performed in order to complete training. The aim of this study is to analyze the applicability of the program with regard to the number of procedures performed during the residency period. A data collection form was designed that included the list of procedures from the program of the specialty; it was sent in April 2014 to all hospitals with accredited residency programs. In September 2014 the forms were analysed, and a general descriptive study was performed; a subanalysis according to the resident's sex and Autonomous region was also performed. The number of procedures performed according to the number of residents in the different centers was also analyzed. The survey was sent to 117 hospitals with accredited programs, which included 190 resident places. A total of 91 hospitals responded (53%). The training offered adapts in general to the specialty program. The total number of procedures performed in the different sub-areas, in laparoscopic and emergency surgery is correct or above the number recommended by the program, with the exception of esophageal-gastric and hepatobiliary surgery. The sub-analysis according to Autonomous region did not show any significant differences in the total number of procedures, however, there were significant differences in endocrine surgery (P=.001) and breast surgery (P=.042). A total of 55% of residents are female, with no significant differences in distribution in Autonomous regions. However, female surgeons operate more than their male counterparts during the residency period (512±226 vs. 625±244; P<.01). The number of residents in the hospital correlates with the number of procedures performed; the residents with more procedures

    To investigate the impact of opioid use on cancer recurrence after oral cancer surgery. We hypothesized that the amount of opioids administered during oral cancer surgery is an independent predictor of recurrence free survival (RFS) and overall survival (OS). After Institutional Review Board approval, we collected demographic, tumor related, intraoperative and survival data of patients who had oral cancer surgery. Multivariable Cox proportional hazards models were used to determine the impact of important covariates on RFS and OS. 268 patients were included. After adjusting for significant covariates, the amount of opioids administered during surgery was not an independent predictor of RFS (HR: 1.27 [CI 95%, 0.838-1.924], p=0.26). However, we observed an association between opioid consumption and shorter OS (HR=1.77, [CI 95%=0.995-3.149]. p=0.05). High requirements of opioids during surgery increase the risk of recurrence and mortality by 27% and 77%, although the association is not statically significant. Copyright © 2017 Elsevier Ltd.

    The feasibility, safety and oncological outcomes of laparoscopic surgery for transverse and descending colon cancers in a community hospital setting were evaluated. Twenty-six patients with transverse or descending colon cancers who underwent laparoscopic surgery at our hospital were included in this retrospective analysis (group A). Their outcomes were compared with those of 71 patients who underwent laparoscopic surgery for colon cancer at other tumor sites (group B). There were no significant differences between the two groups in terms of operative time, estimated blood loss, postoperative hospital stay and morbidity rate. Extended lymphadenectomy was performed more frequently and the number of harvested lymph nodes was significantly higher in group B than in group A. However, no recurrence developed in group A, while recurrence occurred in four patients from group B. The 3-year disease-free survival rates were 100% for group A and 93.5% for group B. The 3-year overall survival rates were 100% for group A and 91.6% for group B. Laparoscopic surgery for transverse and descending colon cancers can be performed safely with oncological validity in a community hospital setting, provided there is careful selection of the patients and adequate lymphadenectomy considering the clinical stage of their disease. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    The optimal delay in the start of chemotherapy following rectal cancer surgery has not yet been identified. However, postponed adjuvant therapy has been proven to be connected with a significant survival detriment. We aimed to investigate whether the time to initiation of adjuvant treatment can be influenced by the application of minimally invasive surgery rather than traditional open surgery. By comprehensively evaluating the available inherent literature, several factors appear to be associated with delayed postoperative chemotherapy. Some of them are strictly related to surgical short-term outcomes. Laparoscopy results in shortened length of hospital stay, reduced surgical morbidity and lower rate of wound infection compared to conventional surgery. Probably due to such advantages, the application of minimally-invasive surgery to treat rectal malignancies seems to impact favorably the possibility to start adjuvant chemotherapy within an adequate timeframe following surgical resection, with potential improvement in patient survival.

    The aim of this study was to develop and validate a prognostication model to predict overall and breast cancer specific survival for women treated for early breast cancer in the UK. Using the Eastern Cancer Registration and Information Centre (ECRIC) dataset, information was collated for 5,694 women who had surgery for invasive breast cancer in East Anglia from 1999 to 2003. Breast cancer mortality models for oestrogen receptor (ER) positive and ER negative tumours were derived from these data using Cox proportional hazards, adjusting for prognostic factors and mode of cancer detection (symptomatic versus screen-detected). An external dataset of 5,468 patients from the West Midlands Cancer Intelligence Unit (WMCIU) was used for validation. Differences in overall actual and predicted mortality were detection for the first time. The model is well calibrated, provides a high degree of discrimination and has been validated in a second UK patient cohort.

    Breast cancer is the most common cancer diagnosis in women, many of whom are of working age, and the five-year survival rate in Sweden is approaching 90%. Accordingly, aspects of working life and sickness absence are of increasing importance for breast cancer survivors and may have a long-term impact on health and quality of life of these women. The aim was to elucidate the work situation and sickness absence during the initial period after breast cancer surgery and to explore factors associated with sickness absence. This is a cross-sectional questionnaire study 4-6 weeks after breast cancer surgery of women aged 20-63 years, and living in Stockholm. A consecutive sample of 933 women were invited and 756 (81%) accepted to participate. Logistic regression analyses were computed to estimate crude and adjusted odds ratios for associations between sick leave and other variables. Most women (86%) were employed (including self-employed) at diagnosis, and 91% of those worked ≥75% of full-time. At time of survey, 56% were on sick leave, the majority for full-time. Low self-rated health, poorer health than before diagnosis, having a strenuous work posture, and younger age were associated with sick leave during the initial period after breast cancer surgery in both univariate and multivariate analyses. The results of this study is not fully consistent compared to previous studies in this field, often performed in later phases after breast cancer surgery or after other cancer diagnoses. Therefore our results indicate that knowledge is needed during all phases of the breast cancer trajectory to determine factors of importance regarding sick leave and their impact throughout the disease trajectory.

    Fertility preservation is important for women of reproductive age with cervical cancer. The underlying reasons behind suboptimal reproductive results after successful fertility-preserving surgery have not yet been fully revealed. The objective of this study was to explore the experience of fertility preservation with radical trachelectomy from the perspective of women with cervical cancer. We conducted interviews with women with cervical cancer who underwent radical trachelectomy using a Grounded Theory methodology with a theoretical framework of symbolic interactionism. Our findings articulate a process in which feminine identity is first threatened by a diagnosis of cancer, then repaired by fertility preservation with radical trachelectomy, and finally reconstructed after the surgery, through interactions with self, others, and external events in women with cervical cancer. Feeling incomplete as a woman because of the loss of the uterus was a critical factor in the women's feeling that their feminine identity was threatened. Thus, fertility preservation was significant for these women. The meaning of fertility preservation varied among the women, and their life perspectives were therefore distinct after the surgery. Women with cervical cancer who undergo radical trachelectomy experience an identity transformation process, and child bearing is not the only expected outcome of fertility preservation. Nurses should coordinate care through the cancer trajectory. Understanding the identity transformation process helps nurses to assess patients' needs and provide appropriate individual care.

    Idiopathic pulmonary fibrosis (IPF) is a progressive diffuse lung disease associated with an increased risk of lung cancer. Patients with IPF sometimes develop a life-threatening acute exacerbation of IPF (AE-IPF) after lung cancer surgery. In this retrospective study, pirfenidone, an antifibrotic agent, was perioperatively administered to IPF patients with lung cancer with the aim of preventing postoperative AE-IPF, and the feasibility and clinical outcomes were investigated. Twelve IPF patients with concomitant lung cancer who received perioperative pirfenidone treatment (PPT) for lung cancer surgery were retrospectively investigated. Sixteen IPF patients undergoing lung cancer surgery without PPT were analyzed as historical controls. Compared to the controls, the PPT patients had a more severely impaired preoperative pulmonary function and a larger number of limited pulmonary resections. There was a significant preoperative decrease in the serum KL-6 levels of the PPT patients. No severe pirfenidone-related complications or IPF-related events occurred in the PPT patients, while six control patients developed AE-IPF (P = 0.0167). A quantitative histopathological evaluation of resected lung specimens found that tissue changes associated with IPF were significantly fewer in the PPT patients (P = 0.021). PPT is a feasible perioperative treatment for IPF patients with lung cancer. Its effectiveness in preventing postoperative AE-IPF thus warrants prospective verification.

    Full Text Available Michael R Shafique, Lary A Robinson, Scott Antonia Department of Thoracic Oncology, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA Abstract: Lung cancer is the most common cancer worldwide and the most common cause of cancer-related death. Non-small-cell lung cancer comprises ~87% of newly diagnosed cases of lung cancer, and nearly one-third of these patients have stage III disease. Despite improvements in the treatment of stage IV lung cancer, particularly with the introduction and dissemination of checkpoint inhibitors, very little progress has been made in the treatment of stage III lung cancer. In this article, we discuss the general staging criteria and treatment options for stage III lung cancer. We review how concurrent radiation and chemotherapy can have immunomodulatory effects, supporting the rationale for incorporating immunotherapy into existing treatment paradigms. Finally, we discuss the results of the PACIFIC trial and implications for the treatment of stage III lung cancer. In the PACIFIC trial, adding durvalumab as a maintenance therapy following the completion of chemoradiotherapy improved progression-free survival in patients with locally advanced unresectable stage III lung cancer. On the strength of these results, durvalumab has been approved by the US Food and Drug Administration for use in this setting, representing the first advance in the treatment of stage III lung cancer in nearly a decade.

    The interferon-stimulated gene 15 ubiquitin-like modifier (ISG15) encodes an IFN-inducible, ubiquitin-like protein. The ISG15 protein forms conjugates with numerous cellular proteins that are involved in a multitude of cellular functions, including interferon-induced immune responses and the regulation of cellular protein turnover. The expression of ISG15 and ISG15-mediated conjugation has been implicated in a wide range of human tumors and cancer cell lines, but the roles of ISG15 in tumorigenesis and responses to anticancer treatments remain largely unknown. In this review, we discuss the findings of recent studies with regard to the role of ISG15 pathways in cancers of the digestive system. PMID:27626310

    There appear to be geographical differences in decisions to perform mastectomy or breast conserving surgery for early-stage breast cancer. This study was carried out to evaluate general surgeons' preferences in breast cancer surgery and to assess the factors predicting cancer practice in Iran. A structured questionnaire was mailed to 235 general surgeons chosen from the address list of the Iranian Medical Council. The questionnaire elicited information about the general surgeons' characteristics and about their work experience, posts they have held, number of breast cancer operations performed per year, preferences for mastectomy or breast conserving surgery, and the reasons for these preferences. In all, 83 surgeons returned the completed questionnaire. The results indicated that only 19% of the surgeons routinely performed breast conserving surgery (BCS) and this was significantly associated with their breast cancer case load (P < 0.01). There were no associations between BCS practice and the other variables studied. The most frequent reasons for not performing BCS were uncertainty about conservative therapy results (46%), uncertainty about the quality of available radiotherapy services (32%), and the probability of patients' non-compliance in radiotherapy (32%). The findings indicate that Iranian surgeons do not routinely perform BCS as the first and the best treatment modality. Further research is recommended to evaluate patients' outcomes after BCS treatment in Iran, with regard to available radiotherapy facilities and cultural factors (patients' compliance)

    The greater omentum is the largest peritoneal fold and can be the origin of primary pathologic conditions, as well as a boundary and conduit for disease processes. Most diseases involving the omentum manifest with nonspecific and overlapping features on computed tomography (CT). In particular, varying benign disease processes of traumatic, inflammatory, vascular, or systemic origin can occur in the omentum during the follow-up period after surgery for intra-abdominal malignancy. It can be challenging for radiologists due to various spectrum of CT findings. Thus, we reviewed the CT findings of various benign omental lesions after surgery for intra-abdominal malignancy.

    Health-related quality of life (HRQL) data are becoming an important supplement to information pertaining to treatment outcome for cancer patients. The purpose of this study was to evaluate the HRQL outcome for oral cancer survivors after surgery plus postoperative radiotherapy (RT) and to investigate the variables associated with their HRQL. Sixty-six oral cancer patients with cancer-free survival after surgery plus postoperative RT of >2 years were enrolled. The Short Form-36 (SF-36) questionnaire in the Taiwan Chinese version was self-reported by all participants at the clinics. The linear regression model was used to analyze the socio-demographic and medical-related variables correlated with the physical component summary (PCS) and mental component summary (MCS) in SF-36. The mean scores of the eight functional domains in the SF-36 were markedly lower for oral cancer survivors compared with the Taiwanese and US norms. Those with older age, lower annual family income, more advanced cancer stage and flap reconstruction had significantly worse PCS, and those with lower annual family income, unemployment and more advanced cancer stage reported significantly worse MCS. This model accounts for 63% of variance in PCS, and 51% in MCS. These results provided patient-reported evidence that oral cancer survivors lived with a worse HRQL compared with the general Taiwanese population. Socio-economic factors and cancer stage were important factors correlated with their HRQL. (authors)

    Surgery is still the best way for treatment of esophageal cancer. The increase in life expectancy and the rising incidence of esophageal tumors have led to a great number of elderly candidates for complex surgery. The purpose of this study was to evaluate the effects of advanced age (70 years or more) on the surgical outcome of esophagectomy for esophageal cancer at a single high-volume center. Between January 2000 and April 2006, 480 cases with esophageal cancer underwent esophagectomy in the referral cancer institute. One hundred sixty-five patients in the elderly group (70 years old or more) were compared with 315 patients in the younger group ( 0.05). With increased experience and care, the outcomes of esophagectomy in elderly patients are comparable to young patients. Advanced age alone is not a contraindication for esophagectomy. (author)

    Full Text Available Abstract Background Prophylactic antibiotics (PAs are beneficial to breast cancer patients undergoing surgery because they prevent surgical site infection (SSI, but limited information regarding their use has been published. This study aims to determine the use of PAs prior to breast cancer surgery amongst breast surgeons in Colombia. Methods An online survey was distributed amongst the breast surgeon members of the Colombian Association of Mastology, the only breast surgery society of Colombia. The scope of the questions included demographics, clinical practice characteristics, PA prescription characteristics, and the use of PAs in common breast surgical procedures. Results The survey was distributed amongst eighty-eight breast surgeons of whom forty-seven responded (response rate: 53.4%. Forty surgeons (85.1% reported using PAs prior to surgery of which >60% used PAs during mastectomy, axillary lymph node dissection, and/or breast reconstruction. Surgeons reported they targeted the use of PAs in cases in which patients had any of the following SSI risk factors: diabetes mellitus, drains in situ, obesity, and neoadjuvant therapy. The distribution of the self-reported PA dosing regimens was as follows: single pre-operative fixed-dose (27.7%, single preoperative dose followed by a second dose if the surgery was prolonged (44.7%, single preoperative dose followed by one or more postoperative doses for >24 hours (10.6%, and single preoperative weight-adjusted dose (2.1%. Conclusion Although this group of breast surgeons is aware of the importance of PAs in breast cancer surgery there is a discrepancy in how they use it, specifically with regards to prescription and timeliness of drug administration. Our findings call for targeted quality-improvement initiatives, such as standardized national guidelines, which can provide sufficient evidence for all stakeholders and therefore facilitate best practice medicine for breast cancer surgery.

    Improved management of colorectal cancer patients has resulted in better five-year survival for rectal cancer compared with colon cancer. We compared excess mortality rates in various time intervals after surgery in patients with colon and rectal cancer. We analysed all patients with curative resection of colorectal cancers reported in the Cancer Registry of Norway before (1994-1996) and after (2001-2003) national treatment guidelines were introduced. Excess mortality was analysed in different postoperative time intervals within the five-year follow-up periods for patients treated in 1994-1996 vs. 2001-2003. A total of 11 437 patients that underwent curative resection were included. For patients treated from 1994 to 1996, excess mortality was similar in colon and rectal cancer patients in all time intervals. For those treated from 2001 to 2003, excess mortality was significantly lower in rectal cancer patients than in colon cancer patients perioperatively (in the first 60 days: excess mortality ratio = 0.46, p = 0.007) and during the first two postoperative years (2-12 months: excess mortality ratio = 0.54, p = 0.010; 1-2 years: excess mortality ratio = 0.60, p = 0.009). Excess mortality in rectal cancer patients was significantly greater than in colon cancer patients 4-5 years postoperatively (excess mortality ratio = 2.18, p = 0.003). Excess mortality for colon and rectal cancer changed substantially after the introduction of national treatment guidelines. Short-term excess mortality rates was higher in colon cancer compared to rectal cancer for patients treated in 2001-2003, while excess mortality rates for rectal cancer patients was significantly higher later in the follow-up period. This suggests that future research should focus on these differences of excess mortality in patients curatively treated for cancer of the colon and rectum.

    Objective: It has been reported by some prospective studies that C-reactive protein (CRP) is associated with cancer risk. However, the correlation between CRP and digestive system cancers has not been evaluated in Chinese females. We conducted a large population-based cohort study to investigate whether elevated level of CRP in serum is associated with an increased risk of digestive system cancers in Chinese women. Methods: From the Chinese Kailuan Female Cohort, 19, 437 women were enrolled in this study in July 2006, and all of the subjects were followed up through 2014. At the baseline investigation, the serum levels of high-sensitivity CRP (hsCRP) were tested for all subjects, and demographic information and risk factor data were collected. Multivariable Cox proportional hazards regression model was used to calculate the hazard ratios ( HR ) and 95% confidence intervals (95% CI ) for the baseline levels of hsCRP after adjusting for age, marital status, smoking, drinking, body mass index (BMI), diabetes and physical activity, and risk of digestive system tumors (including colorectal cancer, stomach cancer, pancreas cancer, liver and gallbladder cancer, and other cancers). Results: By Dec 31, 2014, a total of 100 incident cancer cases were observed, including 47 colorectal cancers, 17 stomach cancers, and altogether 29 pancreas, liver and gallbladder cancers. All the subjects investigated were divided into three groups according to the level of hsCRP (3 mg/L). The 8-year cumulative incidence of digestive system cancers were 405/100 000, 520/100 000 and 787/100 000 in these 3 groups, respectively (Log rank test χ 2 = 8.37, P =0.015). Compared to those with lower hsCRP levels (3 mg/L) had a significantly increased risk of pancreas, liver and gallbladder cancers ( HR = 2.70, 95% CI = 1.06-6.91; P trend = 0.036). Conclusions: Elevated levels of hsCRP at baseline may be associated with increased risk of certain digestive system cancers.

    Conclusions: Longer follow-up still does not show a significant difference in OS and LRFS between both treatments. Because most patients submitted to surgery required adjuvant RT and since its side-effects were not negligible, further studies are warranted to better suit the first treatment for each patient and to prevent the need for adjuvant treatment and the risk of toxicity.

    Purpose Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer.

    MicroRNAs (miRNAs) are identified negatively regulating gene expression and acting as oncogenes or tumor suppressors in tumorigenesis. The association between miR-146a rs2910164 (G>C) polymorphism and susceptibility to digestive system cancers was contradictory and inconsistent in previously published studies. Presently, we performed a comprehensive literature retrieve on PubMed, Web of Science, Embase, Wanfang and CNKI databases to identify all relevant studies published before July 30, 2016. Odds ratio (OR) and 95% confidential interval (95%CI) were used to calculate the relationship between miR-146a rs2910164 (G>C) polymorphism and digestive system cancers susceptibility. Finally, a total of 45 publications comprising 47 separate case-control studies were enrolled in the present updated meta-analysis including 20,281 cases and 26,099 controls. However, no significant association was uncovered for miR-146a rs2910164 polymorphism and digestive system cancers susceptibility in all the genetic models. Moreover, in the stratification analyses by cancer type, the source of control, ethnicity and Hardy-Weinberg Equilibrium (HWE) status, we also revealed a negative result. To conclude, our work suggests that miR-146a rs2910164 (G>C) polymorphism is not a susceptibility factor for digestive system cancers. © 2017 by the Association of Clinical Scientists, Inc.

    Neoadjuvant therapy-induced immunological deterioration may be a key factor in postoperative morbidity in patients with esophageal cancer. This study aimed to determine the effects of perioperative feeding with an immuno-enhanced diet on immune competence in patients treated with neoadjuvant therapy followed by surgery. Because an immuno-enhanced diet that contained several antioxidants was used, perioperative oxidative stress and the effects of the immuno-enhanced diet on this stress were also investigated. Of 39 patients with esophageal cancer who underwent similar surgical procedures, 26 patients who received chemotherapy or chemoradiation therapy before surgery were randomly divided into two groups: group 1 (n= 14) was given an immuno-enhanced diet for 5 days before surgery, and group 2 (n= 12) received no enteral feeding products before surgery. Group 3 (n= 13) consisted of patients that did not receive neoadjuvant therapy and received no enteral feeding products before surgery. Several markers for coagulation and fibrinolysis were determined and immunological assessments were performed for each patient. To measure reactive oxygen metabolites and the total antioxidant capacity, diacron-reactive oxygen metabolites (d-ROMs) and OXY-adsorbent tests were performed using a free radical elective evaluator. Significant depression in lymphocyte numbers was observed in groups 1 and 2 before and early after surgery as compared to group 3. Numbers of B cells, CD4/CD8 ratio, and phytohemagglutinin-induced lymphocyte transformation tests were also significantly decreased in groups 1 and 2 on postoperative day 1. Fibrin and fibrinogen degradation products were significantly elevated in group 2 compared to group 1. d-ROMs and OXY-adsorbent test values were elevated before surgery and were decreased transiently early after surgery. Compared to groups 2 and 3, d-ROMs values were significantly lower in group 1 patients throughout the postoperative period, while OXY

    During the 19th, and for most of the 20th century, malignant tumors were removed by mutilating radical anatomic dissection. Advances such as anesthesia, asepsis, and blood transfusion made possible increasingly more radical operations. There was no scientific rationale for the operations being performed. Surgery in the 20th century was dominated by the principles of William S. Halsted, who contended that the bloodstream was of little significance as a route of tumor cell dissemination; a tumor was autonomous of its host; and cancer was a local-regional disease that spread in an orderly fashion based on mechanical considerations. Halsted believed that both the extent and nuances of an operation influenced patient outcome and that inadequate surgical skill was responsible for the failure to cure. A new surgical era arose in 1957, when cancer surgery began to be influenced by laboratory and clinical research, with results contrary to Halstedian principles. A new hypothesis resulted in a scientific basis for cancer surgery. Clinical trials supported the thesis that operable cancer is a systemic disease and that variations in local-regional therapy are unlikely to substantially affect survival. Complex host-tumor relationships were shown to affect every aspect of cancer and, contrary to Halsted's thesis, the bloodstream is of considerable importance in tumor dissemination. Clinical trials also have shown that less radical surgery is justified. Studies have shown that improved survival can be achieved with systemic therapy after surgery. Such therapy can reduce both the incidence of distant disease and the tumor recurrence at the tumor site after minimal surgery. The use of systemic therapy in patients who have no identifiable metastatic disease is a drastic departure from previous strategies. New technological innovations resulting from engineering research have improved the quality of life of patients by eliminating the need for some surgical procedures. Because cancer

    To predict the probability of lymphedema development in breast cancer patients in the early post-operation stage, we investigated the ability of quantitative lymphoscintigraphic assessment. This retrospective study included 201 patients without lymphedema after unilateral breast cancer surgery. Lymphoscintigraphy was performed between 4 and 8 weeks after surgery to evaluate the lymphatic system in the early postoperative stage. Quantitative lymphoscintigraphy was performed using four methods: ratio of radiopharmaceutical clearance rate of the affected to normal hand; ratio of radioactivity of the affected to normal hand; ratio of radiopharmaceutical uptake rate of the affected to normal axilla (RUA); and ratio of radioactivity of the affected to normal axilla (RRA). During a 1-year follow-up, patients with a circumferential interlimb difference of 2 cm at any measurement location and a 200-mL interlimb volume difference were diagnosed with lymphedema. We investigated the difference in quantitative lymphoscintigraphic assessment between the non-lymphedema and lymphedema groups. Quantitative lymphoscintigraphic assessment revealed that the RUA and RRA were significantly lower in the lymphedema group than in the non-lymphedema group. After adjusting the model for all significant variables (body mass index, N-stage, T-stage, type of surgery, and type of lymph node surgery), RRA was associated with lymphedema (odds ratio=0.14; 95% confidence interval, 0.04-0.46; p=0.001). In patients in the early postoperative stage after unilateral breast cancer surgery, quantitative lymphoscintigraphic assessment can be used to predict the probability of developing lymphedema.

    2017-07-01

    Full Text Available Background: Endoscopic-assisted transoral surgery, including transoral robotic surgery for metastatic retropharyngeal lymph node (RPN from well-differentiated thyroid cancer, has been reported to reduce the complications resulting from transcervical and transmandibular approaches. However, the narrow working space and difficulty identifying RPN are problematic. To solve these issues, several studies have used intraoperative ultrasound in endoscopic-assisted transoral surgery. However, the type of ultrasonography suitable for this purpose remains unclear. Case Presentation: A 60-year-old female with thyroid papillary carcinoma (T4aN1bM0 initially underwent total thyroidectomy and paratracheal and selective neck dissections (D2a, with resectional management of recurrent laryngeal nerve, trachea, and esophagus. Three years later, she was diagnosed with left retropharyngeal and upper mediastinal lymph node metastases of papillary thyroid cancer. Transoral videolaryngoscopic surgery was performed with a combination of ultrasonography with a flexible laparoscopic transducer manipulated with forceps for identifying RPN intraoperatively. Due to the transducer’s small size and thin, flexible cable, the transducer interrupted the procedure in spite of the narrowness of oral cavity. RPN was resected completely without adverse events. Conclusion: We performed intraoperative ultrasound-guided endoscopic transoral surgery for metastatic RPN from papillary thyroid cancer and achieved complete resection as well as preservation of swallowing function.

    Alterations in muscle activation and restricted shoulder mobility, which are common in breast cancer patients, have been found to affect upper limb function. The purpose of this study was to determine muscle activity patterns, and to compare the prevalence of abnormal patterns among the type of breast surgery. In total, 274 breast cancer patients were recruited after surgery. Type of breast surgery was divided into mastectomy without reconstruction (Mastectomy), reconstruction with tissue expander/implant (TEI), latissimus dorsi (LD) flap, or transverse rectus abdominis flap (TRAM). Activities of shoulder muscles were measured using surface electromyography. Experimental analysis was conducted using a Gaussian filter smoothing method with regression. Patients demonstrated different patterns of muscle activation, such as normal, lower muscle electrical activity, and tightness. After adjusting for BMI and breast surgery, the odds of lower muscle electrical activity and tightness in the TRAM are 40.2% and 38.4% less than in the Mastectomy only group. The prevalence of abnormal patterns was significantly greater in the ALND than SLNB in all except TRAM. Alterations in muscle activity patterns differed by breast surgery and reconstruction type. For breast cancer patients with ALND, TRAM may be the best choice for maintaining upper limb function. © 2017 Wiley Periodicals, Inc.

    To evaluate the effect of introducing a robotic program on cost and patient outcome. This was a prospective evaluation of clinical outcome and cost after introducing a robotics program for the treatment of endometrial cancer and a retrospective comparison to the entire historical cohort. Consecutive patients with endometrial cancer who underwent robotic surgery (n=143) were compared with all consecutive patients who underwent surgery (n=160) before robotics. The rate of minimally invasive surgery increased from 17% performed by laparoscopy to 98% performed by robotics in 2 years. The patient characteristics were comparable in both eras, except for a higher body mass index in the robotics era (median 29.8 compared with 27.6; Probotics had longer operating times (233 compared with 206 minutes), but fewer adverse events (13% compared with 42%; Probotics compared with the historical group (Can$7,644 compared with Can$10,368 [Canadian dollars]; Psurgery, the short-term recurrence rate appeared lower in the robotics group compared with the historic cohort (11 recurrences compared with 19 recurrences; Probotics for endometrial cancer surgery increased the proportion of patients benefitting from minimally invasive surgery, improved short-term outcomes, and resulted in lower hospital costs.

    Laser surgery can control intraoperative hemorrhaging and enable lesions to be accurately removed since, unlike an electrotome, it does not effect electrocontractility. It can also reduce postoperative pain and dysfunction. This study investigated the efficacy of laser surgery in recurrent tongue cancer following radiotherapy. Of the total of 105 patients with squamous cell carcinoma of the tongue (T1, T2N0) who underwent radiotherapy at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine, at some point between 1980 and 1998, 24 (22.9%) experienced local recurrence. Sixteen of these patients underwent surgical removal of the tumor. Of these 16 patients, 8 (4 early- and 4 late-stage recurrence) had partial glossectomy by laser surgery. Following laser surgery, 2 (1 early- and 1 late-stage recurrence) of the 8 patients died from neck metastasis and another 2 (early-stage recurrence) died from other diseases. The primary and neck tumors are both under control in 3 (late-stage recurrence) of the remaining 4 patients. Laser surgery for late-stage recurrent tongue cancer following radiotherapy appears to be a suitable treatment, although comprehensive glossectomy with/without radical neck dissection is necessary for early-stage recurrent cases after radiotherapy.

    The success of surgery for thyroid cancer hinges on thorough and accurate preoperative imaging, which enables complete clearance of the primary tumor and affected lymph node compartments. This working group was charged by the Surgical Affairs Committee of the American Thyroid Association to examine the available literature and to review the most appropriate imaging studies for the planning of initial and revision surgery for thyroid cancer. Ultrasound remains the most important imaging modality in the evaluation of thyroid cancer, and should be used routinely to assess both the primary tumor and all associated cervical lymph node basins preoperatively. Positive lymph nodes may be distinguished from normal nodes based upon size, shape, echogenicity, hypervascularity, loss of hilar architecture, and the presence of calcifications. Ultrasound-guided fine-needle aspiration of suspicious lymph nodes may be useful in guiding the extent of surgery. Cross-sectional imaging (computed tomography with contrast or magnetic resonance imaging) may be considered in select circumstances to better characterize tumor invasion and bulky, inferiorly located, or posteriorly located lymph nodes, or when ultrasound expertise is not available. The above recommendations are applicable to both initial and revision surgery. Functional imaging with positron emission tomography (PET) or PET-CT may be helpful in cases of recurrent cancer with positive tumor markers and negative anatomic imaging.

    Introduction: Breast cancer diagnosis and treatment ad evolved over the past quarter century. From self-examination to mammography as main suspicion tool and from radical to conservative surgery plus radiotherapy as prefered treatment. The aim of this review was to assess the evolution of presentation and local management of breast cancer at a Chilean radio-oncology center. Materials and Methods: We analyzed 1.204 breast cancer patients who received postoperative irradiation on two four-years periods.The first period included 223 patients and coincides with the introduction of mammography and conservative surgery. The second included 981 patients managed according to current guidelines. The variables analyzed were type of clinical suspicion, time between clinical suspicion and diagnosis confirmation, type of surgery, histology and tumor size. Data were obtained from medical records and analyzed using STATA 2. Results: In the second period mammographic suspicion reached 39.88%. Time between clinical suspicion and histological diagnosis was reduced to 50%, the proportion of tumors larger than 2 cm was reduced from 61 to 45%, the proportion of DCIS was tripled from 6 to 18%, use of conservative surgery as an absolute increase of 28%. All of these differences were statistically significant (p < 0.01). Conclusion: The introduction of mammography and conservative management allowed early diagnosis of breast cancer in the analyzed population

    Few data are available to assess the learning curve for robotic-assisted surgery for rectal cancer. The aim of the present study was to evaluate the learning curve for robotic-assisted surgery for rectal cancer by a surgeon at a single institute. From December 2011 to August 2013, a total of 80 consecutive patients who underwent robotic-assisted surgery for rectal cancer performed by the same surgeon were included in this study. The learning curve was analyzed using the cumulative sum method. This method was used for all 80 cases, taking into account operative time. Operative procedures included anterior resections in 6 patients, low anterior resections in 46 patients, intersphincteric resections in 22 patients, and abdominoperineal resections in 6 patients. Lateral lymph node dissection was performed in 28 patients. Median operative time was 280 min (range 135-683 min), and median blood loss was 17 mL (range 0-690 mL). No postoperative complications of Clavien-Dindo classification Grade III or IV were encountered. We arranged operative times and calculated cumulative sum values, allowing differentiation of three phases: phase I, Cases 1-25; phase II, Cases 26-50; and phase III, Cases 51-80. Our data suggested three phases of the learning curve in robotic-assisted surgery for rectal cancer. The first 25 cases formed the learning phase.

    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

    Biopsy of the sentinel lymphnode (SLNB), the first lymphnode to receive lymphatic drainage from the primary tumor, accurately predicts the axillary lymph node status and, when negative, obviates the need for axillary lymphadenectomy (AL). The aim of this study was, to verify the SLN localization in breast cancer through preoperative lymphoscintigraphy and intraoperative gamma-probe, as well as to demonstrate the benefits of such techniques in preventing complications of AL. Medical records of 228 patients with breast carcinoma, who were underwent SLN localization and, radioguided surgery, from March 2005 to December 2007 were analyzed retrospectively. Data regarding age, tumor characteristic, breast involved, type of surgery, radiopharmaceutical drainage pattern, axillary assessment (SLNB or AL) and number of lymph nodes dissected were collected. It was ascertained that radioguided surgery is a selective method of axillary assessment in breast cancer, which makes this technique a safe alternative to radical assessment of total dissection of axillary lymph nodes and its subsequent complications.

    Full Text Available Obesity is a major public health problem worldwide especially due to the metabolic disorders which seem to be induced by an excessive amount of adipose tissue. Therefore attention was focused on evaluating the role of bariatric surgery in order to offer a better control of the comorbidities such as diabetes mellitus, arterial hypertension or dyslipidemia which are widely accepted as causes of increased morbidity and mortality among obese patients. Once these benefits have been widely demonstrated, attention was focused on studying the potential protective role of bariatric surgery against development of various malignancies such a breast, endometrial, pancreatic or even colorectal cancer. This is a literature review regarding the potential protective role of bariatric surgery against breast cancer among obese women worldwide.

    To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. A prospective study (Canadian Task Force classification II-1). A gynecologic oncology referral center. Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

    Full Text Available Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR.   Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-third esophageal cancer were randomly assigned to one of two groups. The first group consisted of 50 patients receiving standard chemoradiotherapy (Group A and then undergoing surgery, and the second group consisted of 50 patients undergoing surgery only (Group B. Patients were evaluated with respect to age, gender, clinical symptoms, type of pathology, time of surgery, perioperative blood loss, and number of lymph nodes resected as well as early post-operative complicate including leakage at the anastomosis site, chylothorax and pulmonary complications, hospitalization period, and mortality rate within the first 30 days after surgery.   Results: The mean age of patients was 55 years. Seventy-two patients had squamous cell carcinoma (SCC and 28 patients had adenocarcinoma (ACC. There was no significant difference between the two groups with respect to age, gender, time of surgery, complications including anastomotic leakage, chylothorax, pulmonary complications, cardiac complications, deep venous thrombosis (DVT, or mortality. However, there was a significant difference between the two groups regarding hospital stay, time of surgery, perioperative blood loss, and number of lymph nodes resected.   Conclusion:  The use of NACR did not increase early post-operative complications or mortality among patients with esophageal cancer.

    Minimally invasive surgery in elderly patients with colorectal cancer remains controversial. The study aimed to compare the operative, postoperative, and oncologic outcomes of robotic (robotic colorectal resection surgery [RCRS]) versus laparoscopic colorectal resection surgery (LCRS) in elderly patients with colorectal cancer. Propensity score matching (PSM) was used to compare patients aged 70 years and more undergoing elective RCRS or LCRS for colorectal cancer between 2010 and 2017. Overall, 160 patients underwent elective curative LCRS (n = 102) or RCRS (n = 58) for colorectal cancer. Before PSM, the mean preoperative Charlson score and the tumor size were significantly lower in the robotic group. After matching, 43 RCRSs were compared with 43 LCRSs. The RCRS group showed longer operative times (300.6 versus 214.5 min, P = .03) compared with LCRS, but all other operative variables were comparable between the two groups. No differences were found for postoperative morbidity, mortality, time to flatus, return to regular diet, and length of hospital stay. R0 resection was obtained in 95.3% of procedures. The overall and disease-free survival rates at 1, 2, and 3 years were similar between RCRS and LCRS patients. The presence of more than one comorbidity before surgery was significantly associated with the incidence of postoperative complications. In patients aged 70 years or more, robotic colorectal surgery showed operative and oncologic outcomes similar to those obtained by laparoscopy, despite longer operative times. Randomized trials are awaited to reliably assess the clinical and oncological noninferiority and the costs/benefits ratio of robotic colorectal surgery in elderly populations.

    Radiation therapy in combination with surgery has an important role in the therapy of the head and neck cancer. We conducted a prospective study for patients with head and neck cancer treated with surgery and radiation to evaluate the effect of therapies on the thyroid gland, and to identify the factors that might influence the development of hypothyroidism. From September 1986 through December 1994, 71 patients with head and cancer treated with surgery and radiation were included in this prospective study. Patients' age ranged from 32 to 73 years with a median age of 58 years. There were 12 women and 59 men. Total laryngectomy with neck dissection was carried out in 45 patients and neck dissection alone in 26 patients. All patients were serially monitored for thyroid function before and after radiation therapy. Radiation dose to the thyroid gland ranged from 40.6Gy to 60Gy with a median dose of 50Gy. The follow-up duration was 3 to 80 months. The overall incidence of hypothyroidism was 56.3% (40/71); 7 out of 71 patients (9.9%) developed clinical hypothyroidism and 33 patients (46.4%) developed subclinical hypothyroidism. No thyroid nodules, thyroid cancers, or hyperthyroidism was detected. The risk factor that significantly influenced the incidence of hypothyroidism was a combination of surgery (total laryngectomy with neck dissection) and radiation therapy (P=0.0000). Four of 26 patients (15.4%) with neck dissection alone developed hypothyroidism while 36 of 45 patients (80%) with laryngectomy and neck dissection developed hypothyroidism. The hypothyroidism following surgery and radiation therapy was a relatively common complication. The factor that significantly influenced the incidence of hypothyroidism was combination of surgery and radiation therapy. Evaluation of thyroid function before and after radiation therapy with periodic thyroid function tests is recommended for an early detection of hypothyroidism and thyroid hormone replacement therapy is

    Graves' disease is a common cause of thyrotoxicosis. Treatment options include anti-thyroid medications or definitive therapy: thyroidectomy or radioactive iodine (I(131) ). Traditionally, I(131) has been the preferred definitive treatment for Graves' disease in New Zealand. Reports of concomitant thyroid cancer occurring in up to 17% of Graves' patients suggest surgery, if performed with low morbidity, may be the preferred option. The aim of this study was to determine the rate of thyroid cancer and surgical outcomes in a New Zealand cohort of patients undergoing thyroidectomy for Graves' disease. This study is a retrospective review of Waikato region patients undergoing thyroid surgery for Graves' disease during the 10-year period prior to 1 December 2011. A total of 833 patients underwent thyroid surgery. Of these, 117 were for Graves' disease. Total thyroidectomy was performed in 82, near-total in 33 and subtotal in 2 patients. Recurrent thyrotoxicosis developed in one subtotal patient requiring I(131) therapy. There were two cases of permanent hypoparathyroidism and one of permanent recurrent laryngeal nerve palsy. Eight patients (6.8%) had thyroid cancer detected, none of whom had overt nodal disease. Five were papillary microcarcinomas (one of which was multifocal), two were papillary carcinomas (11 mm and 15 mm) and one was a minimally invasive follicular carcinoma. Thyroid cancer was identified in approximately 7% of patients undergoing surgery for Graves' disease. A low complication rate (<2%) of permanent hypoparathyroidism and nerve injury (<1%) supports surgery being a safe alternative to I(131) especially for patients with young children, ophthalmopathy or compressive symptoms. © 2012 The Authors.

    Full Text Available 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.

    The first aim of our study was to evaluate surgical decision-making by BRCA mutation carriers with breast cancer based on the timing of knowledge of their BRCA mutation status. The second aim was to evaluate breast cancer outcome following surgical treatment. This was a retrospective study of 164 patients diagnosed with invasive breast cancer, tested for BRCA mutation, and treated with primary surgery between 2004 and 2015 at Samsung Medical Center in Seoul, Korea. We reviewed types of surgery and timing of the BRCA test result. We compared surgical decision- making of BRCA carriers with breast cancer based on the timing of knowledge of their BRCA mutation status. Only 15 (9.1%) patients knew their BRCA test results before their surgery, and 149 (90.9%) knew the results after surgery. In patients with unilateral cancer, there was a significant difference between groups whose BRCA mutation status known before surgery and groups whose BRCA status unknown before surgery regarding the choice of surgery (p = 0.017). No significant difference was observed across surgery types of risk of ipsilateral breast tumor recurrence (p = 0.765) and contralateral breast cancer (p = 0.69). Genetic diagnosis before surgery has an impact on surgical decision choosing unilateral mastectomy or bilateral mastectomy in BRCA mutation carriers with breast cancer. Knowledge about BRCA mutation status after initial surgery led to additional surgeries for patients with BCS. Thus, providing genetic counseling and genetic testing before surgical choice and developing treatment strategies for patients with a high risk of breast cancer are important.

    Surgical resection remains as the treatment of choice for non-small cell lung cancer (NSCLC) and provides the best opportunity for cure and long-term survival. Minimally invasive percutaneous ablative therapies, such as radiofrequency ablation (RFA) for treating lung cancers, are currently being studied as treatment alternatives. But, to date, there is little information on comparison of therapeutic effects between surgery and RFA in patients with early stage lung malignancy. We aimed to investigate the clinical significance of RFA as an alternative curative modality for the early stage lung cancer through analyzing the long-term mortality of both treatment groups; surgery vs. RFA. Twenty-two patients of stage I NSCLC were included for this comparative analysis. To minimize confounding effects, we conducted a matching process. In which patients of RFA group (n = 8) were matched with patients of surgery group (n = 14) on the following variables; gender, age (±3 years), tumor node metastasis stage, and calendar year of surgery or RFA (±2 years). The mean survival duration of RFA group and surgery group were 33.18 ± 7.90 and 45.49 ± 7.21, respectively (months, p = 0.297). Log-rank analysis showed that there was no significant difference in overall survival (p = 0.054) between two groups. These results have shown that RFA can offer the survival comparable to that by surgery to stage I NSCLC patients, especially to the patients impossible for the surgery. This study provides an evidence for the use of RFA as a treatment alternative with low procedural morbidity for inoperable early-stage NSCLC patients.

    The pupose of this study was to describe variations in incidence and resection rates of patients with oral cavity squamous cell carcinoma (SCC) in Ontario. All oral cavity SCCs in Ontario between 2003 and 2010 were identified from the Ontario Cancer Registry. Incidence and resection rates along with variations in care were compared by sociodemographic factors and Ontario health regions. The 8-year incidence rates for oral cavity SCC was 21.3 per 100,000 with variations by sex, age group, neighborhood income, and community size. Seventy-four percent of patients underwent an oral cavity cancer resection, of which 91% were at a regional head and neck cancer center. Variations in resection rates existed by region of residence and treatment. Oral cavity cancer incidence rates vary by sex, age, neighborhood income, community size, and health region. Resection rates vary by age and health region. Oral cavity cancer care is highly regionalized in Ontario. © 2015 Wiley Periodicals, Inc. Head Neck 38: 1113-1118, 2016. © 2015 Wiley Periodicals, Inc.

    Background: The available literature on minimally invasive colorectal cancer demonstrates that laparoscopic approach is feasible and associated with better short term outcomes than open surgery while maintaining equivalent oncologic safety. Reports have shown that robotic surgery may overcome some of the pitfalls of laparoscopic intervention. Objective of the work: To evaluate early results of robotic colorectal surgery, in a cohort of Egyptian patients, regarding operative time, operative and early post-operative complications, hospital stay and pathological results. Patients and methods: A case series study which was carried out in surgical department at National Cancer Institute, Cairo University. Ten Egyptian cases of colorectal cancer (age ranged from 30 to 67, 5 males and 5 females) were recruited from the period of April 2013 to April 2014. Robotic surgery was performed to all cases. Results: Three patients had low anterior resection, three anterior resection, one total proctectomy, one abdominoperineal resection, one left hemicolectomy and one colostomy. The study reported no mortalities and two morbidities. The mean operative time was 333 min. The conversion to open was done in only one patient. A total mesorectal excision with negative circumferential margin was accomplished in all patients, distal margin was positive in one patient. Mean lymph nodes removed was 10.7. Mean hospital stay was 7.4 days. Conclusion: To the best of our knowledge, this is the first study reporting the outcomes of robotic colorectal cancer intervention in Egyptian patients. Our preliminary results suggest that robotic- assisted surgery for colorectal cancer can be carried out safely and according to oncological principles

    Early melanoma and non-melanoma skin cancer of the facial area are primarily treated with surgery. Little is known about the outcomes of treatment for facial skin cancer patients. The objective of the study was to identify concerns about aesthetics, procedures and health from the patients' perspective after facial skin surgery. Semi-structured in-depth interviews were conducted with 15 participants. Line-by-line coding was used to establish categories and develop themes. We identified five major themes on the impact of skin cancer surgery: appearance-related concerns; psychological (e.g., fear of new cancers or recurrence); social (e.g. impact on social activities and interaction); physical (e.g. pain and swelling) concerns and satisfaction with the experience of care (e.g., satisfaction with surgeon). The priority of participants was the removal of the facial skin cancer, as this reduced their overall worry. The aesthetic outcome was secondary but important, as it had important implications on the participants' social and psychological functioning. The participants' experience with the care provided by the surgeon and staff also contributed to their satisfaction with their treatment. This conceptual framework provides the basis for the development of a new patient-reported outcome instrument. © 2015 The Australasian College of Dermatologists.

    Although anemia is considered to be a contributor to intra-tumoral hypoxia and tumor resistance to ionizing radiation in cancer patients, the impact of pretreatment anemia on local control after neoadjuvant concurrent chemoradiotherapy (NACRT) and surgery for rectal cancer remains unclear. We reviewed the records of 247 patients with locally advanced rectal cancer who were treated with NACRT followed by curative-intent surgery. The patients with anemia before NACRT (36.0%, 89/247) achieved less pathologic complete response (pCR) than those without anemia (p = 0.012). The patients with pretreatment anemia had worse 3-year local control than those without pretreatment anemia (86.0% vs. 95.7%, p = 0.005). Multivariate analysis showed that pretreatment anemia (p = 0.035), pathologic tumor and nodal stage (p = 0.020 and 0.032, respectively) were independently significant factors for local control. Pretreatment anemia had negative impacts on pCR and local control among patients who underwent NACRT and surgery for rectal cancer. Strategies maintaining hemoglobin level within normal range could potentially be used to improve local control in rectal cancer patients.

    The purpose of this study is to investigate the association between prostate cancer (PCa) patients' regret that their surgery harmed them, and their scores on the two key symptoms of major depressive disorder (depressed mood, anhedonia) and a symptom of melancholic depression (disruption to circadian rhythm). Forty PCa patients who had received surgery for their PCa completed a postal survey including background information, regret about surgery that 'did them a lot of harm' and three items drawn from the Zung Self-Rating Depression Scale measuring depressed mood, anhedonia and circadian rhythm disruption. There were significant correlations between all three symptoms of depression (depressed mood, anhedonia, disruption to circadian rhythm) and between patients' regret that surgery did them a lot of harm and their circadian rhythm disruption, but not between depressed mood or anhedonia and regret about surgery doing harm. These findings suggest that PCa patients' post-surgery regrets about major harm may lead to a significant disruption in a central physiological function and raise the need to consider this side effect of surgery when planning supportive services for these men.

    To compare the perioperative and short-term oncological outcomes of patients who underwent single-port surgery (SPS) with those of patients who underwent multi-port surgery (MPS) for transverse colon cancer. The records of consecutive patients who underwent SPS (n = 75) or MPS (n = 41) for transverse colon cancer in our department between January, 2008 and December, 2015 were analyzed retrospectively. Operative times were significantly shorter in the SPS group than in the MPS group (185 vs. 195 min, respectively; P = 0.043). There were no significant differences in operative procedures, blood loss, or extent of lymph node dissection. The rate of postoperative complications was similar in both groups, but the length of hospital stay was significantly shorter in the single-port group than in the multi-port group (8 vs. 11 days, respectively; P transverse colon cancer.

    Full Text Available One of the components of pathogenetic treatment of patients with breast cancer is castration. The aim of research is to investigate the significance of video assisted laparoscopic surgery on female reproductive organs in the treatment of breast cancer patients. The study is based on analysis of treatment results of 320 breast cancer patients with noncompromised menstruation and presence of steroid hor- mone receptors in tumor tissue. In comparison to surgical techniques used earlier, video assisted endoscopic surgery allows to decrease the aggressiveness of operation, accelerate the rehabilitation of patients, and lower the length of hospital stay. Radiation castration is not always effective: menstruation recovered in some patients. Besides, radiotherapy can not be recommended for patients with patho- logically transformed ovaries. Chemical castration with Zoladex or other analogous drugs is inaccessible for most patients in Russia.

    Treatment results for uterine cervix cancer were evaluated using a new concept named ''Effective Survival Rate''. This rate was calculated by subtracting the weighted sum of incidence rates of various complications from the 5-year survival rate. The numerical values for various complications were assigned as follows: surgical death, 1.0; severe complications, such as fistula ureterovaginalis and ileus, 0.5; mild complications, such as rectum and urinary bladder complications, 0.3 and 0.2. These values were determined with reference to the Karnofsky index of performance status. The effective survival rate was calculated for patients with satage 2 and 3 uterine cervix cancer treated by radiation therapy and surgery, and compared as a function of age between 30 and 70 years. We concluded that the effective survival rate was comparable for radiation therapy and surgery for stage 2 uterine cervix cancer. However, in patients with stage 3, radiation therapy was superior.

    This study reports the development of patient's integrated information-displaying system at image-guided, robotic peroral endoscopic operation of digestive tracts as well as the actual operative field for the operator not to look aside. The peroral endoscope has, at its top, a magnetic position sensor and 2 robotic manipulative forceps at right and left side to navigate the surgery through following 3 windows of superimposing display: the inner peritoneal 3D structure of the real operative field reconstructed from preoperative CT and MR images by volume rendering, presentation of the robot top tip in the structure above and in the preoperative CT or MR image as an ordinary navigation. Furthermore, the robot has a function to measure softness of its grabbing tissue which is displayed in the corresponding right and left superimposing windows, and signs like the real-time blood pressure and heart rate are also given in another window. All of the patient's integrated information-displaying can be handled at will during the operation. Improvement of user interface and of navigation display is further to be conducted. (T.T.)

    In Singapore, the standard of care for endometrial cancer staging remains laparotomy. Since the introduction of gynecologic robotic surgery, there have been more data comparing robotic surgery to laparoscopy in the management of endometrial cancer. This study reviewed clinical outcomes in endometrial cancer in a program that moved from laparotomy to robotic surgery. A retrospective review was performed on 124 consecutive endometrial cancer patients. Preoperative data and postoperative outcomes of 34 patients undergoing robotic surgical staging were compared with 90 patients who underwent open endometrial cancer staging during the same period and in the year before the introduction of robotics. There were no significant differences in the mean age, body mass index, rates of diabetes, hypertension, previous surgery, parity, medical conditions, size of specimens, histologic type, or stage of cancer between the robotic and the open surgery groups. The first 20 robotic-assisted cases had a mean (SD) operative time of 196 (60) minutes, and the next 14 cases had a mean time of 124 (64) minutes comparable to that for open surgery. The mean number of lymph nodes retrieved during robot-assisted staging was smaller than open laparotomy in the first 20 cases but not significantly different for the subsequent 14 cases. Robot-assisted surgery was associated with lower intraoperative blood loss (110 [24] vs 250 [83] mL, P robot-assisted endometrial cancer staging after a relatively small number of cases.

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

    There is sufficient evidence to support both the hormonal influence on the outcome of breast cancer surgery and the SDA hypothesis. The SDA model produces a paradigm shift in the understanding of the natural history of breast cancer. It offers opportunities to try modifying a tumor's biological potential for metastasis (e.g., by tamoxifen, progesterone, antiprotease, or angiostatin) in the neoadjuvant setting. It continues to support the beneficial effects of detection and surgery early in the natural history of disease. It would be worthwhile to plan a trial comparing standard practice (unplanned surgery as the patient enrolls) with surgery during the luteal phase of the menstrual cycle in premenopausal women. Another possibility, based on studies of circulating progesterone, would be to compare primary progesterone treatment (for 4 to 10 days before surgery) with standard practice. Such a trial of primary progesterone is already under way, conducted by the Indian Breast Group. More than 200 patients have enrolled so far. The details of the trial are available from Clinical Research Secretariat, Tata Memorial Centre, Parel, Mumbai, India (e mail: tmho3@bom2.vsnl.in).

    Fifteen patients with advanced, initially inoperable ovarian cancer (stages III and IV) were subjected to second-look surgery between May 1976 and August 1979 following combined radio-chemotherapy. Each case had shown a distinct reduction in tumour size and a demarcation of the foreign issue, which is considered to be prerequisite for second-look surgery. The diagnostic goal of the operation was to verify the success of the preceding radio-chemotherapeutic treatment by means of exact determination of the extent of the residual tumour. The subsequent therapeutic regimen can, if necessary, be modified accordingly. The therapeutic goal is complete surgical removal of the tumour, if at all possible, since the success of subsequent chemotherapy is dependent on the achievement of this aim. The mean interval between initial and second-look surgery was three and a half months. Tumour tissue of varying extent was found in 14 out of 15 cases. In 12 cases total extirpation of the internal genitals was successfully carried out, tumour resection was performed twice, and only of third-look surgery, when after two years of radio-chemotherapy and secondary removal of the internal genitals abdominal tumour diagnosis this patient is now undergoing further chemotherapeutic treatment. We believe that this very case illustrates the importance of second-look surgery and of consistent continuation with radio-chemotherapy in cases of advanced inoperable ovarian cancer. (author)

    Full Text Available 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 2 nd and 7 th 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.

    To evaluate how the introduction of robotic-assisted surgery affects treatment-related morbidity and cost of endometrial cancer (EC) staging. We retrospectively reviewed the records of consecutive patients with stage I-III EC undergoing surgical staging between 2007 and 2012 at our institution. Costs (from surgery to 30days after surgery) were set based on the Medicare cost-to-charge ratio for each year and inflated to 2014 values. Inverse probability weighting (IPW) was used to decrease the allocation bias when comparing outcomes between surgical groups. We focused our analysis on the 251 EC patients who had robotic-assisted surgery and the 384 who had open staging. During the study period, the use of robotic-assisted surgery increased and open staging decreased (P<0.001). Correcting group imbalances by using IPW methodology, we observed that patients undergoing robotic-assisted staging had a significantly lower postoperative complication rate, lower blood transfusion rate, longer median operating time, shorter median length of stay, and lower readmission rate than patients undergoing open staging (all P<0.001). Overall 30-day costs were similar between the 2 groups, with robotic-assisted surgery having significantly higher median operating room costs ($2820 difference; P<0.001) but lower median room and board costs ($2929 difference; P<0.001) than open surgery. Increasing experience with robotic-assisted staging was significantly associated with a decrease in median operating time (P=0.002) and length of stay (P=0.003). The implementation of robotic-assisted surgery for EC staging improves patient outcomes. It provides women the benefits of minimally invasive surgery without increasing costs and potentially improves patient turnover. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available ABSTRACT BACKGROUND The presence of psychiatric symptoms, anger, and personality characteristics are factors that affect the quality of life of newly diagnosed digestive system cancer patients. OBJECTIVE This study aims to identify which stable characteristics of the individual’s personality interfere with quality of life, even when reactive emotional characteristics of falling ill are controlled. METHODS A cross-sectional study was performed at the Oncology Clinic ( Hospital das Clínicas , Marília/SP, Brazil, in which 50 adult patients with digestive system cancer and diagnosed less than 6 months answered the State-Trait Anger Expression Inventory, Temperament and Character Inventory, Hospital Anxiety and Depression Scale and WHOQOL-BREF. Multiple regression was performed to verify if quality of life was related to stable characteristics of the subject’s personality (anger trait, temperament and character after controlling to the transient emotional aspects (anger state, psychiatric symptoms. RESULTS The quality of life psychological health score was higher in presence of self-directedness character and reward dependence temperament and quality of life environment score was higher in presence of self-directedness character and lower in presence of harm avoidance temperament. CONCLUSION The psychological well-being and the adaptive needs to the environment that favoring a better quality of life were reinforced mainly by the self-directedness character; which means that patients more autonomous cope better with the disease. On the other hand, the harm avoidance temperament (meaning the patient has fear of aversive situations impaired the adaptive capacity to deal with the changes of the day-to-day imposed by the disease. Understanding these personality traits is important to the health professionals drive the patient to more successful treatment.

    Full Text Available Objective: Patients with locally advanced breast cancer may undergo breast conserving surgery after neoadjuvant chemotherapy. The aim of the study is to evaluate the results of locally advanced breast cancer patients who underwent breast conserving surgery, axillary dissection and sentinel lymph node biopsy in a single center. Material and Methods: 12 patients with locally advanced breast cancer stage IIIA/IIIB were included in the study between 2002-2009. The patients were given anthracycline-based regimen before surgery. Patients underwent breast conserving surgery, axillary dissection, and sentinel lymph node biopsy followed by radiotherapy. Results: There were five patients in stage IIIA, six in stage IIIB, and one in stage IIIC. Patients had received 3-6 regimen of FAC/FEC. Eight had partial and four had complete response. Five positive axilla were detected. The median value of the lymph nodes was 12 (n:8-19. Five patients underwent sentinel lymph node biopsy. The biopsy has failed in one patient and the median value of dissected sentinel node was 3.5 (n:3-4. Locoregional recurrence was not observed in any patients. The mean follow-up of the patients was 29.8 months and median time was 16 (n:2-80 months.Of the 12 patients 10 are alive and 2 were deceased. Conclusion: In selected locally advanced patients, breast conserving surgery and sentinel lymph node biopsy may be applied by a multidisciplinary approach, and excellent success may be achieved in those patients as in early breast cancer patients.

    Full Text Available Background Today, with improvements in laparoscopy technique, surgery of rectal cancer is performed by laparoscopy. Objectives This study was performed to evaluate oncologic results of open versus laparoscopic surgery of rectal cancer in terms of resection margins, removal of lymph nodes and recurrence rate. Patients and Methods This descriptive-analytic study was performed on 88 patients with middle and lower rectal cancer in the two equivalent groups of laparoscopic and open surgery in Mashhad Ghaem and Omid hospitals during 2011 - 2013. Information including age, sex, number of removed and involved lymph nodes, proximal, distal, and radial margins, tumor stage and location, recurrence and disease-free survival collected in the questionnaire and analyzed using descriptive statistics and frequency distribution tables and t-test. Results Both groups of open and laparoscopic surgery had similar characteristics of age, sex, recurrence and disease-free survival, tumor margins and one-year mortality. The number of removed and involved lymph nodes was higher in the laparoscopic group (5.16 vs. 3.55, respectively, with P < 0.050, and 1.74 vs. 0.59 with P = 0.023, but the ratio of involved lymph nodes to the total number of removed lymph nodes was not different between the two groups (LNR (P = 0.071. Tumor stage was higher in the laparoscopic group and most were in stages II and III (P < 0.001. Conclusions Laparoscopic surgery is an effective technique for safe margin and removing lymph nodes in rectal cancer.

    The influence of recent immobilization or surgery on mortality in cancer patients with venous thromboembolism (VTE) has not been thoroughly studied. We used the RIETE Registry data to compare the 3-month mortality rate in cancer patients with VTE, with patients categorized according to the presence of recent immobilization, surgery or neither. The major outcomes were fatal pulmonary embolism (PE) and fatal bleeding within the first 3 months. Of 6,746 patients with active cancer and acute VTE, 1,224 (18%) had recent immobilization, 1,055 (16%) recent surgery, and 4,467 (66%) had neither. The all-cause mortality was 23.4% (95% CI: 22.4-24.5), and the PE-related mortality: 2.5% (95% CI: 2.1-2.9). Four in every ten patients dying of PE had recent immobilization (37%) or surgery (5.4%). Only 28% of patients with immobilization had received prophylaxis, as compared with 67% of the surgical. Fatal PE was more common in patients with recent immobilization (5.0%; 95% CI: 3.9-6.3) than in those with surgery (0.8%; 95% CI: 0.4-1.6) or neither (2.2%; 95% CI: 1.8-2.6). On multivariate analysis, patients with immobilization were at an increased risk for fatal PE (odds ratio: 1.8; 95% CI: 1.2-2.5). One in every three cancer patients dying of PE had recent immobilization for ≥ 4 days. Many of these deaths could have been prevented with adequate thromboprophylaxis. Copyright © 2014 Elsevier Ltd.

    Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

  4. Primary surgery for differentiated thyroid cancer in the new millennium.

    Differentiated thyroid cancers (DTC) are malignancies of follicular cell derivation. Histopathologically and oncologically, DTC fall into two broad tumor categories: papillary (PTC) and follicular thyroid cancer (FTC). These major tumor categories, based on clinical manifestation and biological behavior, are further subdivided into low-risk [papillary microcarcinoma (mPTC); minimally invasive follicular cancer (MIFTC)] and high-risk DTC [PTC>1 cm or metastatic; MIFTC with histopathological angioinvasion; widely invasive FTC (WIFTC)]. Recently, a surgical approach has been adopted that differentiates between low-risk and high-risk DTC. The rationale behind this new concept is to better balance oncologic risk (high vs low) with the surgical morbidity attendant to the procedure (recurrent laryngeal nerve palsy and hypoparathyroidism). This surgical risk is larger with routine total thyroidectomy (TT) and central node dissection (CND) than with less than TT or TT without CND.Whereas TT with CND remains the treatment of choice for high-risk DTC with metastases, the extent of thyroid resection and lymph node dissection can be reduced in low-risk PTC and FTC without demonstrable loss of oncological benefit. In the new millennium, the surgical approach to DTC, especially low-risk PTC and FTC, has undergone considerable change, resulting in less extensive procedures. This risk-adapted strategy relies not only on the skillful histopathologic detection of multifocality in PTC and vascular invasion in MIFTC, but likewise necessitates diligent follow-up to spot and adequately treat local recurrences and distant metastases as they become clinically apparent.

    Surgical margin status in cancer surgery represents an important oncologic parameter affecting overall prognosis. The risk of disease recurrence is minimized and survival often prolonged if margin-negative resection can be accomplished during cancer surgery. Unfortunately, negative margins are not always surgically achievable due to tumor invasion into adjacent tissues or involvement of critical vasculature. Herein, we present a novel intra-operative device created to facilitate a uniform and mild heating profile to cause hyperthermic destruction of vessel-encasing tumors while safeguarding the encased vessel. We use pancreatic ductal adenocarcinoma as an in vitro and an in vivo cancer model for these studies as it is a representative model of a tumor that commonly involves major mesenteric vessels. In vitro data suggests that mild hyperthermia (41-46 °C for ten minutes) is an optimal thermal dose to induce high levels of cancer cell death, alter cancer cell's proteomic profiles and eliminate cancer stem cells while preserving non-malignant cells. In vivo and in silico data supports the well-known phenomena of a vascular heat sink effect that causes high temperature differentials through tissues undergoing hyperthermia, however temperatures can be predicted and used as a tool for the surgeon to adjust thermal doses delivered for various tumor margins.

    There are still few comparison reports regarding the safety of salvage surgery for recurrence and persistence following platinum-based chemoradiotherapy (CRT) and cetuximab-based bioradiotherapy (BRT), which are frequently used as non-surgical therapies for advanced head and neck carcinomas. This study compared the safety of salvage surgery following CRT against that following BRT for advanced hypopharyngeal cancer. The study examined 34 cases who underwent salvage surgery following CRT and 7 cases who underwent salvage surgery following BRT from September 2002 to December 2015. The number of cases that were able to undergo salvage surgery was 34 among 67 recurrence and persistence cases following CRT and 7 of 8 cases following BRT. In terms of the surgical procedure, salvage neck dissection was conducted for 22 cases in the CRT group and 5 cases in the BRT group, with no significant differences observed between both including the surgical time and amount of bleeding, and with no major complications in either group. Total hypopharynx or total laryngectomy resection for salvage was conducted for 19 cases in the CRT group and 3 cases in the BRT group, upon which we observed anastomotic leakage in 3 cases in the CRT group and 1 case in the BRT group; however, there was no significant difference in the onset frequency. There was no clear difference regarding safety between salvage surgery following CRT and following BRT for locally advanced hypopharyngeal cancer. However, regarding the adaptation of salvage surgery, the possibility of limitations in the CRT group was suggested in comparison with the BRT group. (author)

    The aim of this study was to review the feasibility of selective sentinel lymph node biopsy in patients with previous surgery for breast cancer, as well as to examine the factors that may interfere with sentinel node detection. A retrospective review was performed on 91 patients with breast cancer and previous breast surgery, and who underwent sentinel lymph node biopsy. Patients were divided into two groups according to their previous treatment: aesthetic breast surgery in 30 patients (group I) and breast-conserving surgery in 61 (group II). Lymphoscintigraphy was performed after an intra-tumour injection in 21 cases and a peri-areolar injection in 70 cases. An analysis was made of lymphatic drainage patterns and overall sentinel node detection according to clinical, pathological and surgical variables. The overall detection of the sentinel lymph node in the lymphoscintigraphy was 92.3%, with 7.7% of extra-axillary drainages. The identification rate was similar after aesthetic breast surgery (93.3%) and breast-conserving surgery (91.8%). Sentinel lymph nodes were found in the contralateral axilla in two patients (2.2%), and they were included in the histopathology study. The non-identification rate in the lymphoscintigraphy was 7.7%. There was a significantly higher non-detection rate in the highest histological grade tumours (28.6% grade III, 4.5% grade I and 3.6% grade II). Sentinel lymph node biopsy in patients with previous breast surgery is feasible and deserves further studies to assess the influence of different aspects in sentinel node detection in this clinical scenario. A high histological grade was significantly associated with a lower detection. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

Observational study of two cohorts comparing patients undergoing rectal tumor surgery using TaETM or conventional ETM after a minimum of six months of intestinal transit reconstruction. EORTC-30, EORTC-29 quality of life questionnaires and the anorectal function assessment questionnaire (LARS score) are applied. General variables are also collected. 31 patients between 2011 and 2014: 15 ETM group and 16 TaETM. We do not find statistically significant differences in quality of life questionnaires or in anorectal function. Statistically significant general variables: longer surgical time in the TaETM group. Nosocomial infection and minor suture failure in the TaETM group. The performance of TaETM achieves the same results in terms of quality of life and anorectal function as conventional ETM.

    Colorectal surgery is the standard treatment for patients with colorectal cancer. To overcome two of the main challenges, the circumferential resection margin and postoperative complications, real-time tissue assessment could be of great benefit during surgery. In this ex vivo study, diffuse reflectance spectroscopy (DRS) was used to differentiate tumor tissue from healthy surrounding tissues in patients with colorectal neoplasia. DRS spectra were obtained from tumor tissue, healthy colon, or rectal wall and fat tissue, for every patient. Data were randomly divided into training (80%) and test (20%) sets. After spectral band selection, the spectra were classified using a quadratic classifier and a linear support vector machine. Of the 38 included patients, 36 had colorectal cancer and 2 had an adenoma. When the classifiers were applied to the test set, colorectal cancer could be discriminated from healthy tissue with an overall accuracy of 0.95 (±0.03). This study demonstrates the possibility to separate colorectal cancer from healthy surrounding tissue by applying DRS. High classification accuracies were obtained both in homogeneous and inhomogeneous tissues. This is a fundamental step toward the development of a tool for real-time in vivo tissue assessment during colorectal surgery.

    The association between metabolism and cancer has been recently emphasized. This study aimed to find the prognostic significance of obesity in advanced stage rectal cancer patients treated with surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 111 patients who were treated with combined surgery and RT for clinical stage 2–3 (T3 or N+) rectal cancer between 2008 and 2014. The prognostic significance of obesity (body mass index [BMI] ≥25 kg/m{sup 2}) in local control was evaluated. The median follow-up was 31.2 months (range, 4.1 to 85.7 months). Twenty-five patients (22.5%) were classified as obese. Treatment failure occurred in 33 patients (29.7%), including local failures in 13 patients (11.7%), regional lymph node failures in 5, and distant metastases in 24. The 3-year local control, recurrence-free survival, and overall survival rates were 88.7%, 73.6%, and 87.7%, respectively. Obesity (n = 25) significantly reduced the local control rate (p = 0.045; 3-year local control, 76.2%), especially in women (n = 37, p = 0.021). Segregation of local control was best achieved by BMI of 25.6 kg/m{sup 2} as a cutoff value. Obese rectal cancer patients showed poor local control after combined surgery and RT. More effective local treatment strategies for obese patients are warranted.

    Objective: To study the cosmetic outcome and curative effect of 6 MV X-ray tangential field radiotherapy for early stage breast cancer after conservative surgery. Methods: The eligible criteria were single tumor ≤3 cm in diameter, surgical margin negative and lymph node negative. The exclusive criteria were inflammatory carcinoma or male breast cancer. After conservative surgery, 42 patients with stage 0, I or II breast cancer were treated with conventional radiotherapy with a total dose of 50 Gy to the whole breast and 10 Gy boost to the tumor bed. The efficacy and the cosmetic outcome of radiotherapy were evaluated every 3 months for the first 2 years and every 6 months after that and every 12 months after 5 years. Results: The follow up time was 19-90 months (median 56 months). Two patients died of metastasis after 16 months and 36 months, which was diagnosed by CT scan. Excellent or good cosmetic outcome was > 93% at 36 months. The local control rate was 100%. The 1- and 3-year survival rates was 100% and 98%, respectively. Conclusions: Tangential field radiotherapy for early breast cancer after conservative surgery has a satisfied result in both tumor control and cosmetic outcome, which can definitely improve the life quality of the patients.

    Minimum volume thresholds were introduced in France in 2008 to improve the quality of cancer care. We investigated whether/how the quality of treatment decisions in breast cancer surgery had evolved before and after this policy was implemented. We used Hospital Episode Statistics for all women having undergone breast conserving surgery (BCS) or mastectomy in France in 2005 and 2012. Three surgical procedures considered as better treatment options were analyzed: BCS, immediate breast reconstruction (IBR) and sentinel lymph node biopsy (SLNB). We studied the mean rates and variation according to the hospital profile and volume. Between 2005 and 2012, the volume of breast cancer surgery increased by 11% whereas one third of the hospitals no longer performed this type of surgery. In 2012, the mean rate of BCS was 74% and similar in all hospitals whatever the volume. Conversely, IBR and SLNB rates were much higher in cancer centers (CC) and regional teaching hospitals (RTH) [IBR: 19% and 14% versus 8% on average; SLNB: 61% and 47% versus 39% on average]; the greater the hospital volume, the higher the IBR and SLNB rates (p < 0.0001). Overall, whatever the surgical procedure considered, inter-hospital variation in rates declined substantially in CC and RTH. We identified considerable variation in IBR and SLNB rates between French hospitals. Although more complex and less standardized than BCS, most clinical guidelines recommended these procedures. This apparent heterogeneity suggests unequal access to high-quality procedures for women with breast cancer. Copyright © 2015 Elsevier Ltd. All rights reserved.

    BACKGROUND Despite national emphasis on care coordination, little is known about how fragmentation affects cancer surgery outcomes. Our study examines a specific form of fragmentation in post-discharge care—readmission to a hospital different from the location of the operation—and evaluates its causes and consequences among patients readmitted after major cancer surgery. STUDY DESIGN We used the State Inpatient Database of California (2004 to 2011) to identify patients who had major cancer surgery and their subsequent readmissions. Logistic models were used to examine correlates of non-index readmissions and to assess associations between location of readmission and outcomes, measured by in-hospital mortality and repeated readmission. RESULTS Of 9,233 readmissions within 30 days of discharge after major cancer surgery, 20.0% occurred in non-index hospitals. Non-index readmissions were associated with emergency readmission (odds ratio [OR] = 2.63; 95% CI, 2.26–3.06), rural residence (OR = 1.81; 95% CI, 1.61–2.04), and extensive procedures (eg hepatectomy vs proctectomy; OR = 2.77; CI, 2.08–3.70). Mortality was higher during non-index readmissions than index readmissions independent of patient, procedure, and hospital factors (OR = 1.31; 95% CI, 1.03–1.66), but was mitigated by adjusting for conditions present at readmission (OR = 1.24; 95% CI, 0.98–1.58). Non-index readmission predicted higher odds of repeated readmission within 60 days of discharge from the first readmission (OR = 1.16; 95% CI, 1.02–1.32), independent of all covariates. CONCLUSIONS Non-index readmissions constitute a substantial proportion of all readmissions after major cancer surgery. They are associated with more repeated readmissions and can be caused by severe surgical complications and increased travel burden. Overcoming disadvantages of non-index readmissions represents an opportunity to improve outcomes for patients having major cancer surgery. PMID:27016905

    Full Text Available Abstract Background Common measures of surgical quality are 30-day morbidity and mortality, which poorly describe breast cancer surgical quality with extremely low morbidity and mortality rates. Several national quality programs have collected additional surgical quality measures; however, program participation is voluntary and results may not be generalizable to all surgeons. We developed the Breast Cancer Surgical Outcomes (BRCASO database to capture meaningful breast cancer surgical quality measures among a non-voluntary sample, and study variation in these measures across providers, facilities, and health plans. This paper describes our study protocol, data collection methods, and summarizes the strengths and limitations of these data. Methods We included 4524 women ≥18 years diagnosed with breast cancer between 2003-2008. All women with initial breast cancer surgery performed by a surgeon employed at the University of Vermont or three Cancer Research Network (CRN health plans were eligible for inclusion. From the CRN institutions, we collected electronic administrative data including tumor registry information, Current Procedure Terminology codes for breast cancer surgeries, surgeons, surgical facilities, and patient demographics. We supplemented electronic data with medical record abstraction to collect additional pathology and surgery detail. All data were manually abstracted at the University of Vermont. Results The CRN institutions pre-filled 30% (22 out of 72 of elements using electronic data. The remaining elements, including detailed pathology margin status and breast and lymph node surgeries, required chart abstraction. The mean age was 61 years (range 20-98 years; 70% of women were diagnosed with invasive ductal carcinoma, 20% with ductal carcinoma in situ, and 10% with invasive lobular carcinoma. Conclusions The BRCASO database is one of the largest, multi-site research resources of meaningful breast cancer surgical quality data

    One hundred and sixteen cases of brain metastases of lung cancer were retrospectively analysed with special reference to the relative significance of surgery and radiotherapy. The median survival time from diagnosis of brain metastases was 1.2 months in 27 cases without treatment, 2.5 months in 51 cases treated by surgery alone, 4.2 months in 31 cases treated by radiotherapy alone and 6.5 months in 7 cases treated by surgery and radiotherapy. The survival rate in patients treated by radiotherapy was significantly better than in those not treated by radiotherapy. However, the effect of surgery was not significant in prolongation of survival time. On the other hand, the rate of improvement in neurological symptoms assessed at one month after the initiation of treatment was 80.9% in 47 cases treated by surgery and 19.4 % in 31 cases treated by radiotherapy. The result suggested that surgery is superior to radiotherapy in alleviating neurological symptoms. It is important to understand the nature of effect of each treatment. A better result will be anticipated by proper selection or combination of these treatments. (author)

    Most malignancies are diagnosed in older adults who are potentially susceptible to aging-related health conditions; however, the manifestation of geriatric syndromes during surgical cancer treatment is not well quantified. Accordingly, we sought to assess the prevalence and ramifications of geriatric events during major surgery for cancer. Using Nationwide Inpatient Sample data from 2009 to 2011, we examined hospital admissions for major cancer surgery among elderly patients (ie, age ≥ 65 years) and a referent group age 55 to 64 years. From these observations, we identified geriatric events that included delirium, dehydration, falls and fractures, failure to thrive, and pressure ulcers. We then estimated the collective prevalence of these events according to age, comorbidity, and cancer site and further explored their relationship with other hospital-based outcomes. Within a weighted sample of 939,150 patients, we identified at least one event in 9.2% of patients. Geriatric events were most common among patients age ≥ 75 years, with a Charlson comorbidity score ≥ 2, and who were undergoing surgery for cancer of the bladder, ovary, colon and/or rectum, pancreas, or stomach (P geriatric event had a greater likelihood of concurrent complications (odds ratio [OR], 3.73; 95% CI, 3.55 to 3.92), prolonged hospitalization (OR, 5.47; 95% CI, 5.16 to 5.80), incurring high cost (OR, 4.97; 95% CI, 4.58 to 5.39), inpatient mortality (OR, 3.22; 95% CI, 2.94 to 3.53), and a discharge disposition other than home (OR, 3.64; 95% CI, 3.46 to 3.84). Many older patients who receive cancer-directed surgery experience a geriatric event, particularly those who undergo major abdominal surgery. These events are linked to operative morbidity, prolonged hospitalization, and more expensive health care. As our population ages, efforts focused on addressing conditions and complications that are more common in older adults will be essential to delivering high-quality cancer care. © 2016 by

    Full Text Available The endoscopic treatment of cancerous and precancerous lesions in the gastrointestinal (GI tract has experienced major breakthroughs in the past years. Endoscopic mucosal resection (EMR is a simple and efficient method for the treatment of most benign lesions in the GI tract. However, with the introduction of endoscopic submucosal dissection (ESD and endoscopic full-thickness resection (EFTR, the scope of lesions eligible for endoscopic treatment has been widened significantly even in the colon. These methods are now being used routinely not just for the treatment of benign lesions but also in the curative en bloc resection of early colorectal cancers. The quick, efficient, and noninvasive character of these endoscopic procedures make them not just an alternative to surgery but, in many cases, the methods of choice for the treatment of most early colon cancers and some rectal cancers.

    Background. To investigate the patterns of relapse following intensity modulated radiotherapy (IMRT) given after radical surgery for oral and oropharyngeal squamous cell cancer. Patients and methods. One hundred and two patients with oral or oropharyngeal cancer were treated with radical surgery followed by IMRT up to a mean total dose of 60 Gy between years 2001 and 2007. Thirty-nine of the patients (%) also received concomitant weekly cisplatin. Forty of the patients had oral and 62 had oropharyngeal cancer. Data on the tumour, patient and treatment factors were collected. Following therapy the patients were followed by clinical examination, endoscopy and MRI/CT at 2- to 3-months interval up to 2 years and thereafter at 6-month intervals. Results. The mean follow-up time of the patients was 55 months (range, 26-106 months). The rate for local tumour control for the whole cohort was 92.2%: 87.5% for oral cancer patients and 96.7% for oropharyngeal cancer patients. The 5-year disease specific survival was 90.2% and 5-year overall survival 84.3%. During the follow-up eight locoregional recurrences were observed, three at the primary tumour site and one at regional nodal site and four at both sites. The mean time to primary tumour recurrence was seven months (range, 2-10 months) and to nodal recurrence seven months (range, 2-12 months). Distant metastasis occurred in six (6%) patients. The factors associated with poor prognosis were the primary tumour size and tumour site with oral cancers having worse outcome. The treatment was well tolerated with no unexpected toxicities. The most frequent late toxicity was dysphagia necessitating permanent PEG in five patients. This was correlated with the advanced primary tumour size and resulting in wide tumour excision and reconstruction. Conclusions. Surgery combined with postoperative radiotherapy given as IMRT results in low level of tumour recurrence

    Predictors for postoperative recovery after colorectal cancer surgery are usually investigated in relation to length of stay (LoS), readmission, or 30-day morbidity. This study describes patient characteristics and surgery-related factors associated with patient-reported recovery 1 and 6 months after surgery. In total, 153 consecutively included patients who were recovering from colorectal cancer surgery reported their level of recovery using the Postoperative Recovery Profile. Multiple logistic regression analysis was used to calculate associations with recovery, defined as good or poor, divided into five recovery dimensions: physical symptoms, physical functions, psychological, social and activity. Better preoperative health predicted good recovery regarding three dimensions 1 month after surgery. Regarding all dimensions 1 month after surgery, poor recovery was predicted by a poor recovery on the day of discharge within corresponding dimensions. Higher age was associated with good recovery 6 months after surgery, while chemotherapy showed negative associations. Overall, a majority of factors had a negative impact on recovery, but without any obvious relation to one specific dimension or point in time. Those factors were: high Body Mass Index, comorbidity, abdominoperineal resection, loop ileostomy, colostomy and LoS. This study illustrates the complexity of postoperative recovery and a need for individualised follow-up strategies. © 2017 John Wiley & Sons Ltd.

    To describe our experience with cisplatin- and paclitaxel-based IP chemotherapy in patients treated initially with either neoadjuvant chemotherapy and interval debulking surgery (IDS) or primary cytoreductive surgery (PCRS). We performed a retrospective review of the records of 67 patients (38 IDS, 29 PCRS) enrolled in the intraperitoneal (IP) chemotherapy program at the Tom Baker Cancer Centre between 2006 and 2009. Information pertaining to patient demographics, IP chemotherapy toxicity, and catheter complications was extracted, and the median time to recurrence was calculated. Most patients in the study were aged 50 to 70 years and had a diagnosis of stage III serous ovarian cancer. Overall, 295/393 IP cycles (75%) were successfully administered. The proportion of patients completing six cycles of chemotherapy in the IDS and PCRS groups was 53% and 59%, respectively. Frequent (> 25%) Grade 1 to 2 chemotherapy toxicities included fatigue, peripheral neuropathy, and nausea. Catheter complications were observed in 34% of patients (23/67). The recurrence rates for patients completing four or more cycles of IP chemotherapy in the IDS and PCRS groups were 58% and 35%, respectively, with the median time to recurrence approximately one year. Although IP chemotherapy is well tolerated in both IDS and PCRS patients, the median time to recurrence is shorter than expected.

    Deleted in Malignant Brain Tumors 1 (DMBT1) has been proposed as a candidate tumor suppressor gene for brain, lung, and digestive tract cancer. In particular, alterations of the gene and/or a loss of expression have been observed in gastric, colorectal, and esophageal carcinomas. Initial evidence...... has accumulated that DMBT1 may represent a multifunctional protein. Because the consequences of a loss of DMBT1 function may be different depending on its original function in a particular tissue, we wondered if it is appropriate to assume a uniform role for DMBT1 in digestive tract carcinomas. We...... hypothesized that a systematic characterization of DMBT1 in the human alimentary tract would be useful to improve the understanding of this molecule and its role in digestive tract carcinomas. Our data indicate that the expression pattern and subcellular distribution of DMBT1 in the human alimentary tract...

    2014-01-14

    To systematically review the evidence for the effectiveness of fast-track program vs traditional care in laparoscopic or open surgery for gastric cancer. PubMed, Embase and the Cochrane library databases were electronically searched for published studies between January 1995 and April 2013, and only randomized trials were included. The references of relevant studies were manually searched for further studies that may have been missed. Search terms included "gastric cancer", "fast track" and "enhanced recovery". Five outcome variables were considered most suitable for analysis: postoperative hospital stay, medical cost, duration to first flatus, C-reactive protein (CRP) level and complications. Postoperative hospital stay was calculated from the date of operation to the date of discharge. Fixed effects model was used for meta-analysis. Compared with traditional care, fast-track program could significantly decrease the postoperative hospital stay [weighted mean difference (WMD) = -1.19, 95%CI: -1.79--0.60, P = 0.0001, fixed model], duration to first flatus (WMD = -6.82, 95%CI: -11.51--2.13, P = 0.004), medical costs (WMD = -2590, 95%CI: -4054--1126, P = 0.001), and the level of CRP (WMD = -17.78, 95%CI: -32.22--3.35, P = 0.0001) in laparoscopic surgery for gastric cancer. In open surgery for gastric cancer, fast-track program could also significantly decrease the postoperative hospital stay (WMD = -1.99, 95%CI: -2.09--1.89, P = 0.0001), duration to first flatus (WMD = -12.0, 95%CI: -18.89--5.11, P = 0.001), medical cost (WMD = -3674, 95%CI: -5025--2323, P = 0.0001), and the level of CRP (WMD = -27.34, 95%CI: -35.42--19.26, P = 0.0001). Furthermore, fast-track program did not significantly increase the incidence of complication (RR = 1.39, 95%CI: 0.77-2.51, P = 0.27, for laparoscopic surgery; and RR = 1.52, 95%CI: 0.90-2.56, P = 0.12, for open surgery). Our overall results suggested that compared with traditional care, fast-track program could result in shorter

    Background The aim of this study was to evaluate the chronological changes in epidemiological factors and surgical outcomes in patients with lung cancer who underwent surgery in a single Japanese institution. Patients and methods A clinicopathological database of patients with lung cancer who underwent surgery with curative intent from January 1974 to December 2014 was reviewed. The chronological changes in various factors, including patient’s age, sex, histological type, tumor size, pathological stage (p-stage), surgical method, operative time, intraoperative blood loss, 30-day mortality, and postoperative overall survival (OS), were evaluated. Results A total of 1,616 patients were included. The numbers of resected patients, females, adenocarcinomas, p-stage IA patients, and age at the time of surgery increased with time, but tumor size decreased (all P<0.0001). Concerning surgical methods, the number of sublobar resections increased, but that of pneumonectomies decreased (P<0.0001). The mean operative time, intraoperative blood loss, and the postoperative 30-day mortality rate decreased (all P<0.0001). When the patients were divided into two groups (1974–2004 and 2005–2014), the 5-year OS rates for all patients and for p-stage IA patients improved from 44% to 79% and from 73% to 89%, respectively (all P<0.0001). The best 5-year OS rate was obtained for sublobar resection (73%), followed by lobectomy (60%), combined resection (22%), and pneumonectomy (21%; P<0.0001). Conclusion Changes in epidemiological factors, a trend toward less invasive surgery, and a remarkably improved postoperative OS were confirmed, which demonstrated the increasingly important role of surgery in therapeutic strategies for lung cancer.

    Patients with lung cancer report sleep difficulties to be frequent and bothersome symptoms. This study describes the trajectory of sleep from before and up to 12 months after surgery for lung cancer. Further, it investigates possible associations between sleep disturbance, demographic and clinical characteristics before surgery. This study is part of a longitudinal multicentre study. Sleep disturbance was measured by The General Sleep Disturbance Scale (GSDS) that investigates frequencies of sleep difficulties (21 items) and a total sum score ≥43 indicates a clinically meaningful level of sleep disturbance (score range 0-147). Linear mixed models were used to study changes in sleep from baseline to 1, 5, 9 and 12 months after surgery. The percentage of patients (n = 264) reporting sleep disturbances was 60.9% at baseline, 68.5% at Month 1, 55.4% at Month 5, 51.3% at Month 9 and 49.7% at Month 12. The increase to and decrease from Month 1 was the only significant alteration in the occurrence of sleep disturbance. The patients reported most problems within the subscales sleep quantity, early awakenings and sleep quality. Factors associated with sleep disturbance were lower age, use of pain medication and psychotropic medication and higher comorbidity score. Lung cancer patients sleep poorly, before as well as after surgery. There is a need to address sleeping disturbance routinely in clinical practice and screening for sleeping problems is indicated. Further studies are warranted concerning factors that contribute to sleep disturbance and how they best can be treated. © The Author 2017.

    Minimal access surgery for gastrointestinal cancer has short-term benefits but is associated with a proficiency-gain curve. The aim of this study was to define national proficiency-gain curves for minimal access colorectal and oesophagogastric surgery, and to determine the impact on clinical outcomes. All adult patients undergoing minimal access oesophageal, colonic and rectal surgery between 2002 and 2012 were identified from the Hospital Episode Statistics database. Proficiency-gain curves were created using risk-adjusted cumulative sum analysis. Change points were identified, and bootstrapping was performed with 1000 iterations to identify a confidence level. The primary outcome was 30-day mortality; secondary outcomes were 90-day mortality, reintervention, conversion and length of hospital stay. Some 1696, 15 008 and 16 701 minimal access oesophageal, rectal and colonic cancer resections were performed during the study period. The change point in the proficiency-gain curve for 30-day mortality for oesophageal, rectal and colonic surgery was 19 (confidence level 98·4 per cent), 20 (99·2 per cent) and three (99·5 per cent) procedures; the mortality rate fell from 4·0 to 2·0 per cent (relative risk reduction (RRR) 0·50, P = 0·033), from 2·1 to 1·2 per cent (RRR 0·43, P curve for reintervention in oesophageal, rectal and colonic resection was 19 (98·1 per cent), 32 (99·5 per cent) and 26 (99·2 per cent) procedures respectively. There were also significant proficiency-gain curves for 90-day mortality, conversion and length of stay. The introduction of minimal access gastrointestinal cancer surgery has been associated with a proficiency-gain curve for mortality and major morbidity at a national level. Unnecessary patient harm should be avoided by appropriate training and monitoring of new surgical techniques. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    2016-06-01

    Sarcopenic dysphagia is characterized by the loss of swallowing muscle mass and function associated with generalized loss of skeletal muscle mass and function. In this report, the authors describe a patient with possible sarcopenic dysphagia after lung cancer surgery and was treated subsequently by rehabilitation nutrition. A 71-year-old man with lung cancer experienced complications of an acute myocardial infarction and pneumonia after surgery. He was ventilated artificially, and a tracheotomy was performed. The patient received diagnoses of malnutrition, severe sarcopenia, and possible sarcopenic dysphagia. His dysphagia was improved by a combination of dysphagia rehabilitation including physical and speech therapy and an improvement in nutrition initiated by a nutrition support team. Finally, he no longer had dysphagia and malnutrition. Sarcopenic dysphagia should be considered in patients with sarcopenia and dysphagia. Rehabilitation nutrition using a combination of both rehabilitation and nutritional care management is presumptively useful for treating sarcopenic dysphagia.

    Advances in surgical techniques and paradigm changes in rectal cancer treatment have led to a drastic decline in the abdominoperineal resection rate, and sphincter-preserving operation is possible in distal rectal cancer. The aim of this study is to evaluate the long-term incidence of permanent stoma after sphincter-preserving surgery for low rectal cancer and its corresponding risk factors. From 2000 to 2014, patients who underwent sphincter-preserving low anterior resection for low rectal cancer (within 5 cm from the anal verge) were included. The occurrence of permanent stoma over time and its risk factors were investigated by using a Cox proportional hazards regression model. This study included 194 patients who underwent ultra-low anterior resection for distal rectal cancer, and the median follow-up period was 77 months for the surviving patients. Forty-six (23.7%) patients required a permanent stoma eventfully. Anastomotic-related complications and disease progression were the main reasons for permanent stoma.

    Swallowing is a complex neuromuscular process that requires anatomical indemnity and an adequate coordination of several organs. Laryngeal cancer treatment may cause swallowing disorders. Traditionally, a high frequency of this type of disorder after surgery has been reported, but no actual data concerning its incidence in patients undergoing radiotherapy for early laryngeal cancer has been published. Aim. To compare swallowing disorders frequency posterior to treatment in early laryngeal cancer patients. Material and Method. Two groups of early laryngeal cancer patients were transversally studied, one treated with vertical partial surgery (CP), and the other treated exclusively with radiotherapy. Each patient had otorhinolaryngological, nasofibroscopic and video fluoroscopic evaluations after treatment. Differences between groups were compared using the - square test. Results. Twenty patients per group were entered in this study, predominantly males of similar age. Both groups presented a high incidence of aspiration symptoms (55% in RT and 35% in CP). There were no significant differences between both groups. Discussion and Conclusion. A high incidence of swallowing disorders in patients treated for early laryngeal cancer was found. It should then be considered as a frequent alteration in this group of patients, either treated with RT or CP

    Erectile dysfunction is a common side-effect of prostate cancer surgery that causes men suffering and hinders their sexual recovery. There are studies that describe men's and partners' distress and couples' difficulties engaging in sexual recovery. A few studies show a short-term benefit of brief psycho-social interventions such as psychoeducation and counseling. However, there is no conceptual framework to guide psychosocial treatments. We propose a model of intervention in sexual recovery that incorporates grief and mourning as a gateway to new and satisfying sexuality after prostate cancer treatment.

    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

    Treatment in advanced stage epithelial ovarian cancer (EOC) is based on primary cytoreductive surgery followed by platinum-based chemotherapy. Successful cytoreduction to minimal residual tumour burden is the most important determinant of prognosis. However, extensive surgical procedures to achieve maximal debulking are inevitably associated with postoperative morbidity and mortality. The objective of this study is to determine predictors of 30-day morbidity after primary cytoreductive surgery for advanced stage EOC. All patients in the South Western part of the Netherlands who underwent primary cytoreductive surgery for advanced stage EOC between January 2004 and December 2007 were identified from the Rotterdam Cancer Registry database. All peri- and postoperative complications within 30 days after surgery were registered and classified according to the definitions of the National Surgical Quality Improvement Programme (NSQIP). To investigate independent predictors of 30-day morbidity, a Cox proportional hazards model with backward stepwise elimination was utilised. The identified predictors were entered into a nomogram. Two hundred and ninety-three patients entered the study protocol. Optimal cytoreduction was achieved in 136 (46%) patients. 30-day morbidity was seen in 99 (34%) patients. Postoperative morbidity could be predicted by age (P=0.007; odds ratio [OR] 1.034), WHO performance status (P=0.046; OR 1.757), extent of surgery (P=0.1308; OR=2.101), and operative time (P=0.017; OR 1.007) with an optimism corrected c-statistic of 0.68. 30-day morbidity could be predicted by age, WHO performance status, operative time and extent of surgery. The generated nomogram could be valuable for predicting operative risk in the individual patient.

    Minimally invasive techniques have revolutionized the field of general surgery over the few last decades. Despite its advantages, in complex procedures such as rectal surgery, laparoscopy has not achieved a high penetration rate because of its steep learning curve, its relatively high conversion rate and technical challenges. The aim of this study was to present a single center experience with robotic surgery for rectal cancer focusing mainly on early and mid-term postoperative outcome. A series of 100 consecutive patients who underwent robotic rectal surgery between January 2008 and June 2012 was analyzed retrospectively in terms of demographics, pathological data, surgical and oncological outcomes. Seventy-seven patients underwent robotic sphincter-saving resection, and 23 patients underwent robotic abdominoperineal resection. There were 4 conversions. The median operative time for sphincter-saving procedures was 180 min. The median time for robotic abdominoperineal resection was 160 min. The median distal resection margin of the operative specimen was 3 cm. The median number of retrieved lymph nodes was 14. The median hospital stay was 10 days. In-hospital mortality was nil. The overall morbidity was 30%. Four patients presented transitory postoperative urinary dysfunction. Severe erectile dysfunction was reported by 3 patients. The median length of follow-up was 24 months. The 3-year overall survival rate was 90%. Robotic surgery is advantageous for both surgeons (in that it facilitates dissection in a narrow pelvis) and patients (in that it affords a very good quality of life via the preservation of sexual and urinary function in the vast majority of patients and it has low morbidity and good midterm oncological outcomes). In rectal cancer surgery, the robotic approach is a promising alternative and is expected to overcome the low penetration rate of laparoscopy in this field. Celsius.

    Endoscopic CO 2 laser surgery (ELS) is a widely accepted treatment modality for early laryngeal cancer. Commonly re- ported advantages of ELS are good oncologic results with low incidence of complications. Although less common if com- pared with open procedures, complications following ELS can be very serious, even with lethal outcome. They can range from intraoperative endotracheal tube fire accidents to early and late postoperative sequels that require intensive medical treatment, blood tra...

    Tumors of the nasal cavity and paranasal sinuses present a challenge to treat them. A combination of surgery and radiation therapy can improve treatment outcomes in 49-56% [1, 2] of the patients with locally advanced nasal cavity and paranasal sinus cancer. The midface reconstruction poses a formidable challenge to the reconstructive surgeon due to the region's complex skeletal and soft-tissue anatomy. The rehabilitation program including the reconstruction of the resected orbital walls using the porous and mesh implants from titanium nickelid (TiNi) was developed at the Cancer Research institute jointly with the Research Institute of Medical Materials. The technique was proven effective, allowing the natural position of the eye and visual function to be preserved in 90% [1-3] of the patients. A long period of reparative processes and risk of developing inflammation in the implant area, as well as the need to decrease length of surgery, contributed to the development of a novel approach to repairing the midface bone structures using the implant based on the microporous wire and TiNi mesh. Eighteen patients with nasal cavity and paranasal sinus cancer were treated using the combined thin implants. The novel technique allowed the time of the implant installation to be reduced to 5-10 min. The structure of the implant contributed to prevention of inflammatory processes in 97% [1, 2] of cases. Thus, the natural position of the eyeball and visual function were preserved in 100% [1, 3, 4] of patients. The use of the TiNi implants in reconstructive surgery for patients with nasal cavity and paranasal sinus cancer led to reduced time of surgery and rehabilitation, increased level of social adaptation of patients and improved cosmetic and functional results.

The technique involves a local medially based, wedge shaped, fasciocutaneous transposition flap from the lateral region of the thoracic area. Overall satisfaction and aesthetic satisfaction surveys were conducted with the patients during a 6-month postoperative follow-up period. Aesthetic results in terms of breast shape and symmetry were evaluated by plastic surgeons.ResultsThe average specimen weight was 76.8 g. The locations of the masses were the upper lateral quadrant (n=15, the lower lateral quadrant (n=2, and the central lateral area (n=3. Complications developed in four of the cases, partial flap necrosis in one, wound dehiscence in one, and fat necrosis in two. The majority of the patients were satisfied with their cosmetic outcomes.ConclusionsPartial breast reconstruction using a lateral thoracodorsal flap is well matched with breast color and texture, and the surgery is less aggressive than other techniques with few complications. Therefore, the lateral thoracodorsal flap can be a useful, reliable technique in correcting breast deformity after breast conserving surgery, especially in laterally located breast cancer.

    Single-incision laparoscopic surgery (SILS) is a feasible and safe procedure for colorectal cancer. However, SILS has some technical limitations such as collision between instruments and inadequate countertraction. We present a hybrid single-incision laparoscopic surgery (hybrid SILS) technique for colon cancer that involves use of one additional 5 mm trocar. Hybrid SILS for colon cancer was attempted in 70 consecutive patients by a single surgeon between August 2014 and July 2016 at Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine. Using prospectively collected data, an observational study was performed on an intention-to-treat basis. Hybrid SILS was technically completed in 66 patients, with a failure rate of 5.7% (4/70). One patient was converted to open surgery for para-aortic lymph node dissection. Another was converted to open surgery due to severe peritoneal adhesion. An additional trocar was inserted for adhesiolysis in the other two cases. Median lengths of proximal and distal margins were 12.8 cm (interquartile range [IQR], 10.0-18.6), and 8.2 cm (IQR, 5.5-18.3), respectively. Median total number of lymph nodes harvested was 24 (IQR, 18-33). Overall rate of postoperative morbidity was 12.9%, but there were no Clavien-Dindo grade III or IV complications. There was no postoperative mortality or reoperation. Median postoperative hospital stay was 6 days (IQR, 5-7). Hybrid SILS using one additional 5 mm trocar is a safe and effective minimally invasive surgical technique for colon cancer. Experienced laparoscopic surgeons can perform hybrid SILS without a learning curve based on the formulaic surgical techniques presented in this article.

    The relationship between surgery, chemotherapy irradiation and the immunological state in patients of laryngeal cancer with or without metastasis was investigated. The lymphocyte reaction to PHA (Phytohaemagglutinin) stimulation and T-lymphocyte count was examined before and immediately after the therapy in 66 patients divided into three groups. From the results the authors conclude that surgical treatment, partial or total laryngectomy, with or without radical Neckdissection influence the immunological state of the patients at least chemotherapy more and irradiation at most.

    A permanent colostomy is a serious limitation of the quality of life. Besides cure of cancer, preservation of sphincter function is an important goal of surgery for rectal cancer. In a prospective study a concept offering every patient with rectal cancer either sphincter salvage or a "neosphincter" was investigated, and the impact of this strategy on oncologic results, sphincter function, and quality of life was analyzed. From 1992 to 1997, 276 patients were accepted for the study. Two hundred sixty-one patients had elective surgery, and 15 patients had emergency surgery for their rectal tumors. The postoperative mortality rate was 4 percent. A radical resection (R0) was possible in 197 patients (75 percent). Anterior resection was the most common procedure (n = 87), and intersphincteric resection with coloanal anastomosis was the preferred method for low tumors (n = 65). Abdominoperineal resection was necessary in 15 cases. Thirteen patients had an immediate restoration of sphincter function by means of a dynamic graciloplasty, and 2 patients needed emergency abdominoperineal resection for bleeding. The follow-up was relatively short (median, 36.4 months) at the time of data analysis and showed a local recurrence rate of 8 percent. Although postoperative continence according to the Williams score revealed satisfactory results, subjective quality of life and the scale for specific symptoms showed a significantly worse outcome in patients with ultralow (coloanal) anastomoses compared with those with anterior resection. We conclude that for elective curative surgery of rectal cancer, a permanent colostomy is not necessary provided all presently available techniques of sphincter salvage and restoration are applied. However, the patient has to be informed about possible side effects associated with surgical procedures such as coloanal anastomosis or neosphincter reconstruction, to avoid severe psychological difficulties.

    This study seeks to evaluate assessment of geriatric frailty and nutritional status in predicting postoperative mortality in gastric cancer surgery. Preoperatively, patients operated for gastric adenocarcinoma underwent assessment of Groningen Frailty Indicator (GFI) and Short Nutritional Assessment Questionnaire (SNAQ). We studied retrospectively whether these scores were associated with in-hospital mortality. From 2005 to September 2012 180 patients underwent surgery with an overall mortality of 8.3%. Patients with a GFI ≥ 3 (n = 30, 24%) had a mortality rate of 23.3% versus 5.2% in the lower GFI group (OR 4.0, 95%CI 1.1-14.1, P = 0.03). For patients who underwent surgery with curative intent (n = 125), this was 27.3% for patients with GFI ≥ 3 (n = 22, 18%) versus 5.7% with GFI gastric cancer surgical mortality and geriatric frailty as well as nutritional status using a simple questionnaire. This may have implications in preoperative decision making in selecting patients who optimally benefit from surgery.

    Preventing breast cancer recurrence after breast-conserving surgery is an important issue. The main factors contributing to such recurrence are positive margins, absence of radiotherapy and young age. To investigate the clinical significance of age in breast-conserving surgery, we examined the relationship between clinicopathological findings or outcome and age, especially young age. The cases were divided into three groups by age; 35 years old or less, 36-50y.o. and 51y.o. or higher. Between April 1989 and March 2003, 743 patients were treated with breast-conserving surgery. There were 49 patients aged 35 years old or less (6.6%). Younger age significantly correlated with positive surgical margin, lymph node metastases, higher proliferative activity, negative estrogen receptor (ER) or progesterone receptor (PgR), larger tumor size, and shorter nipple-tumor distances. Although younger patients had a higher recurrence rate irrespective of radiotherapy, margin status had an impact on recurrence rate. Thus, the reason young age was a significant factor for breast recurrence after breast-conserving surgery was that young patients frequently had numerous risk factors such as positive margin, higher proliferative activity, positive nodes, negative ER/PgR and larger tumor. However, negative surgical margins could reduce recurrence rates even in young women. These results suggest that more suitable criteria and strategies may be needed for young patients with breast cancer. (author)

    Clinician-reported toxicity grading through common terminology criteria for adverse events (CTCAE) stages dysphagia based on symptoms, diet, and tube dependence. The new dynamic imaging grade of swallowing toxicity (DIGEST) tool offers a similarly scaled five-point ordinal summary grade of pharyngeal swallowing as determined through results of a modified barium swallow (MBS) study. This study aims to inform clinicians on the similarities and differences between dysphagia severity according to clinical CTCAE and MBS-derived DIGEST grading. A cross-sectional sample of 95 MBS studies was randomly selected from a prospectively-acquired MBS database among patients treated with organ preservation strategies for head and neck cancer. MBS DIGEST and clinical CTCAE dysphagia grades were compared. DIGEST and CTCAE dysphagia grades had "fair" agreement per weighted κ of 0.358 (95% CI .231-.485). Using a threshold of DIGEST ≥ 3 as reference, CTCAE had an overall sensitivity of 0.50, specificity of 0.84, and area under the curve (AUC) of 0.67 to identify severe MBS-detected dysphagia. At less than 6 months, sensitivity was 0.72, specificity was 0.76, and AUC was 0.75 while at greater than 6 months, sensitivity was 0.22, specificity was 0.90, and AUC was 0.56 for CTCAE to detect dysphagia as determined by DIGEST. Classification of pharyngeal dysphagia on MBS using DIGEST augments our understanding of dysphagia severity according to the clinically-derived CTCAE while maintaining the simplicity of an ordinal scale. DIGEST likely complements CTCAE toxicity grading through improved specificity for physiologic dysphagia in the acute phase and improved sensitivity for dysphagia in the late-phase.

    We studied and analyzed therapeutic outcomes of a radical surgery under local anesthesia for breast cancer in our department. Subjects were 53 patients with breast cancer whose diagnoses were definitely made before surgery. Indications were: localized ductal carcinoma in situ (DCIS) diagnosed preoperatively; invasive carcinoma less than 3 cm in tumor diameter on ultrasound and magnetic resonance imaging scan; and clinically tumors with negative axillary lymph nodes. Operative procedures included microdochectomy or lumpectomy associated with sentinel lymph node navigation biopsy (SLNB). We could perform the operation under local anesthesia in all the 53 patients, and were not demanded to shift from local to general anesthesia. Surgical stumps were positive in 10 patients (18.9%). Of the ten patients, additional resection was performed in one, and irradiation was added to the remaining nine patients. SLNB was performed in a total of 39 patients, six (15.4%) patients of them had metastasis and two out of the six patients underwent additional axillary lymph node dissection. None of serious complications were encountered. Local recurrence and hepatic metastasis occurred in each one patient in an averaged observation period of 15.1 months. This day's radical operation under local anesthesia for breast cancer is a useful procedure as minimally invasive surgery as for the indications employed in this study. (author)

    To analyze the outcomes of chemoradiotherapy for extrahepatic bile duct (EHBD) cancer patients who underwent R2 resection or bypass surgery and to identify prognostic factors affecting clinical outcomes, especially in terms of molecular biomarkers. Medical records of 21 patients with EHBD cancer who underwent R2 resection or bypass surgery followed by chemoradiotherapy from May 2001 to June 2010 were retrospectively reviewed. All surgical specimens were re-evaluated by immunohistochemical staining using phosphorylated protein kinase B (pAKT), CD24, matrix metalloproteinase 9 (MMP9), survivin, and {beta}-catenin antibodies. The relationship between clinical outcomes and immunohistochemical results was investigated. At a median follow-up of 20 months, the actuarial 2-year locoregional progression-free, distant metastasis-free and overall survival were 37%, 56%, and 54%, respectively. On univariate analysis using clinicopathologic factors, there was no significant prognostic factor. In the immunohistochemical staining, cytoplasmic staining, and nuclear staining of pAKT was positive in 10 and 6 patients, respectively. There were positive CD24 in 7 patients, MMP9 in 16 patients, survivin in 8 patients, and {beta}-catenin in 3 patients. On univariate analysis, there was no significant value of immunohistochemical results for clinical outcomes. There was no significant association between clinical outcomes of patients with EHBD cancer who received chemoradiotherapy after R2 resection or bypass surgery and pAKT, CD24, MMP9, survivin, and {beta}-catenin. Future research is needed on a larger data set or with other molecular biomarkers.

    The aim of the present study was to examine the risk factors of high-output ileostomy (HOI), which is associated with electrolyte abnormalities and/or stoma complications, and to create a prediction model. The medical records of 68 patients who underwent colorectal cancer surgery with ileostomy between 2011 and 2016 were retrospectively investigated. All the patients underwent surgical resection for colorectal cancer at the Osaka Medical Center for Cancer and Cardiovascular Diseases (Osaka, Japan). A total of 7 patients with inadequate data on ileostomy output were excluded. Using a group of 50 patients who underwent surgery between 2011 and 2013, the risk of HOI was classified by a decision tree model using a partition platform. The HOI prediction model was validated in an additional group of 11 patients who underwent surgery between 2014 and 2016. Univariate analysis of clinical factors demonstrated that young age (P=0.003) and high white blood cell (WBC) count (Pmodel, three factors (gender, age and WBC on postoperative day 1) were generated for the prediction of HOI. The patients were classified into five groups, and HOI was observed in 0-88% of patients in each group. The area under the curve (AUC) was 0.838. The model was validated by an external dataset in an independent patient group, for which the AUC was 0.792. In conclusion, HOI patients were classified and an HOI prediction model was developed that may help clinicians in postoperative care.

At a median follow-up of 20 months, the actuarial 2-year locoregional progression-free, distant metastasis-free and overall survival were 37%, 56%, and 54%, respectively. On univariate analysis using clinicopathologic factors, there was no significant prognostic factor. In the immunohistochemical staining, cytoplasmic staining, and nuclear staining of pAKT was positive in 10 and 6 patients, respectively. There were positive CD24 in 7 patients, MMP9 in 16 patients, survivin in 8 patients, and β-catenin in 3 patients. On univariate analysis, there was no significant value of immunohistochemical results for clinical outcomes. There was no significant association between clinical outcomes of patients with EHBD cancer who received chemoradiotherapy after R2 resection or bypass surgery and pAKT, CD24, MMP9, survivin, and β-catenin. Future research is needed on a larger data set or with other molecular biomarkers.

    Auditing is an important tool to identify practice variation and 'best practices'. The Dutch Pancreatic Cancer Audit is mandatory in all 18 Dutch centers for pancreatic surgery. Performance indicators and case-mix factors were identified by a PubMed search for randomized controlled trials (RCT's) and large series in pancreatic surgery. In addition, data dictionaries of two national audits, three institutional databases, and the Dutch national cancer registry were evaluated. Morbidity, mortality, and length of stay were analyzed of all pancreatic resections registered during the first two audit years. Case ascertainment was cross-checked with the Dutch healthcare inspectorate and key-variables validated in all centers. Sixteen RCT's and three large series were found. Sixteen indicators and 20 case-mix factors were included in the audit. During 2014-2015, 1785 pancreatic resections were registered including 1345 pancreatoduodenectomies. Overall in-hospital mortality was 3.6%. Following pancreatoduodenectomy, mortality was 4.1%, Clavien-Dindo grade ≥ III morbidity was 29.9%, median (IQR) length of stay 12 (9-18) days, and readmission rate 16.0%. In total 97.2% of >40,000 variables validated were consistent with the medical charts. The Dutch Pancreatic Cancer Audit, with high quality data, reports good outcomes of pancreatic surgery on a national level. Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc.

    Delays to surgical breast cancer treatment of 90 days or more may be associated with greater stage migration. We investigated racial disparities in time to receiving first surgical treatment in breast cancer patients. Insured black (56 %) and white (44 %) women with primary breast cancer completed telephone interviews regarding psychosocial (e.g., self-efficacy) and health care factors (e.g., communication). Clinical data were extracted from medical charts. Time to surgery was measured as the days between diagnosis and definitive surgical treatment. We also examined delays of more than 90 days. Unadjusted hazard ratios (HRs) examined univariate relationships between delay outcomes and covariates. Cox proportional hazard models were used for multivariate analyses. Mean time to surgery was higher in blacks (mean 47 days) than whites (mean 33 days; p = .001). Black women were less likely to receive therapy before 90 days compared to white women after adjustment for covariates (HR .58; 95 % confidence interval .44, .78). Health care process factors were nonsignificant in multivariate models. Women with shorter delay reported Internet use (vs. not) and underwent breast-conserving surgery (vs. mastectomy) (p interventions to address delay are needed.

    The International Agency for Research on Cancer (IARC) identifies ten infectious agents (viruses, bacteria, parasites) able to induce cancer disease in humans. Among parasites, a carcinogenic role is currently recognized to the digenetic trematodes Schistosoma haematobium, leading to bladder cancer, and to Clonorchis sinensis or Opisthorchis viverrini, which cause cholangiocarcinoma. Furthermore, several reports suspected the potential association of other parasitic infections (due to Protozoan or Metazoan parasites) with the development of neoplastic changes in the host tissues. The present work shortly reviewed available data on the involvement of parasites in neoplastic processes in humans or animals, and especially focused on the carcinogenic power of Cryptosporidium parvum infection. On the whole, infection seems to play a crucial role in the etiology of cancer.

    Objective: To assess whether patients with early stage bilateral breast cancer can be treated with definitive irradiation following breast-conserving surgery with acceptable survival, local control, complication rates, and cosmetic outcomes. Material and Methods: We reviewed 55 cases of patients with synchronous or sequential bilateral breast cancer treated with definitive irradiation following breast-conserving surgery at our institution from 1977 to 1992. Analysis of cases was limited to women who were AJCC clinical Stage 0, I, and II. The records of these 55 patients with 110 treated breasts were reviewed for tumor size, histology, AJCC stage, pathologic axillary lymph nodes status, first and overall site(s) of failure, and adjuvant chemotherapy or hormonal therapy. Analysis regarding matching technique, cosmetic outcome, and complication rate was also performed. The 5- and 10-year overall survival (OS), no evidence of disease (NED) survival, relapse-free survival (RFS), and local control rates were evaluated. Twelve women (22%) presented with synchronous bilateral carcinoma, and 43 women (78%) had sequential bilateral carcinoma. Of the 12 patients with synchronous cancer, 5 received adjuvant chemotherapy, 2 received Tamoxifen, and 1 received both adjuvant therapies. Of the 43 patients with sequential cancer, 6 received chemotherapy, 1 received Tamoxifen, and 1 received both adjuvant therapies for the first cancer treatment; seven received chemotherapy and 6 received Tamoxifen for the second cancer treatment. Results: The median age at the time of treatment of the first cancer was 56 years (range 26-86 years). For the 12 patients with synchronous cancer, the median follow-up was 48 months (range 9-164). For the 43 patients with sequential cancer, the median follow-up was 112 months (range 52-188 months) after the first cancer, and 59 months (range 11-153 months) after the second. The median dose delivered was 64 Gy (range 42-72 Gy) using a combination of

  7. Lack of association between methionine synthase A2756G polymorphism and digestive system cancer risk: evidence from 3,9327 subjects.

    Full Text Available BACKGROUND: Polymorphisms in genes involved in the metabolism of folate and methyl groups have been implicated with risk of digestive system cancer. Methionine synthase (MTR plays a central role in folate metabolism, thereby affecting DNA methylation. The association between A2756G polymorphism (rs1805087 in MTR and digestive system cancer susceptibility was inconsistent in previous studies. To investigate this inconsistency, we performed this meta-analysis. METHODS: Databases including Pubmed, EMBASE, ISI Web of Science and China National Knowledge Infrastructure (CNKI were searched to find relevant studies. Odds ratios (ORs with 95% confidence intervals (CIs were used to assess the strength of association. Potential sources of heterogeneity were also assessed by subgroup analysis and meta-regression. RESULTS: A total of 29 articles with 15,368 patients and 23,959 controls were included. We found no association between MTR A2756G polymorphism and digestive system cancer in overall population (G allele: OR = 1.03, 95% CI = 0.98-1.09, P = 0.25; dominant model: OR = 1.03, 95% CI = 0.97-1.10, P = 0.33; recessive model: OR = 1.02, 95% CI = 0.89-1.17, P = 0.79. In the stratified analyses according to cancer type, sample size and genotyping method, no evidence of any gene-disease association was obtained in almost all genetic models. However, marginal significant associations were found for East Asians and hospital-based studies. CONCLUSIONS: This meta-analysis suggests that there is no significant association between the MTR A2756G polymorphism and digestive system cancer risk.

    Full Text Available Summary: Background: Given the global increase in aging populations and cancer incidence, understanding the influence of age on postoperative outcome after cancer surgery is imperative. This study aimed to evaluate the impact of age on survival outcome in solid cancer patients receiving curative surgery. Methods: A total of 37,288 patients receiving curative surgeries for solid cancers between 2007 and 2012 at four affiliated Chang Gung Memorial Hospital were included in the study. All patients were categorized into age groups by decades for survival analysis. Results: The percentages of patient populations aged <40 years, 40–49 years, 50–59 years, 60–69 years, 70–79 years, and ≥80 years were 9.7%, 17.7%, 27.8%, 22.1%, 16.9%, and 5.7%, respectively. The median follow-up period was 38.9 months (range, 22.8–60.4 months and the overall, cancer-specific, and noncancer-specific mortality rates were 26.0%, 17.6%, and 8.5%, respectively. The overall mortality rate of patients in different age groups were 18.5%, 21.1%, 22.0%, 25.3%, 35.3%, and 49.0%, respectively. Compared to patients aged <40 years, more significant decrease in long-term survival were observed in aging patients. Multivariate analysis showed higher postoperative short-term mortality rates in patients older than 70 years, and the adjusted odds ratio of mortality risk ranged from 1.47 to 1.74 and 2.26 to 3.03 in patients aged 70–79 years and ≥80 years, respectively, compared to those aged <40 years. Conclusion: Aging was a negative prognostic factor of survival outcome in solid cancer patients receiving curative surgery. After adjustment of other clinicopathologic factors, the influence of age on survival outcome was less apparent in the elderly. Keywords: Age, Solid cancer, Surgical resection, Prognosis

    Eighty-two patients with cervical esophageal cancer were treated by definitive chemoradiotherapy (10 patients) or surgery (72 patients) between 1989 and 2009 at the Kurume University Hospital. The 3-year overall survival rate after surgery was 51% and that after definitive chemoradiotherapy was 44%, showing no significant difference between the two groups. The 3-year local control rate after surgery was significantly better than that after definitive chemoradiotherapy. The overall 5-year survival rate of patients requiring a mediastinal tracheostomy was 11%, while that of those without a mediastinal tracheostomy was 39%. There was no significant difference between the two groups. The commencement of oral intake took a long time after treatment in patients with a T4 tumor who underwent chemoradiotherapy and who had vocal fold paralysis. Almost all patients who underwent esophageal reconstruction using the alimentary tract after pharyngolaryngoesophagectomy could take food within two weeks after surgery. On the other hand, in patients with vocal cord paralysis after cervical esophagectomy without laryngectomy, several months were needed after surgery to take food orally. (author)

    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

    Recent interest has focused on the role of perioperative epidural analgesia in improving cancer outcomes. The heterogeneity of studies (tumour type, stage and outcome endpoints) has produced inconsistent results. Clinical practice also highlights the variability in epidural effectiveness. We considered the novel hypothesis that effective epidural analgesia improves cancer outcomes following gastro-oesophageal cancer surgery in patients with grouped pathological staging. Following institutional approval, a database analysis identified 140 patients, with 2-year minimum follow-up after gastro-oesophageal cancer surgery. All patients were operated on by a single surgeon (2005-2010). Information pertaining to cancer and survival outcomes was extracted. Univariate analysis demonstrated a 1-year 14% vs. 33% (P = 0.01) and 2-year 27% vs. 40% [hazard ratio (HR)=0.59; 95% CI, 0.32-1.09, P = 0.087] incidence of cancer recurrence in patients with (vs. without) effective (> 36 h duration) epidural analgesia, respectively. Multivariate analysis demonstrated increased time to cancer recurrence (HR = 0.33; 95% CI: 0.17-0.63, P benefit (HR = 0.42; 95% CI: 0.21-0.83, P benefit in patients with oesophageal cancer (HR = 0.34; 95% CI: 0.16-0.75, P = 0.005) and in patients with tumour lymphovascular space infiltration (LVSI), (HR = 0.49; 95% CI: 0.26-0.94, P = 0.03). Effective epidural analgesia improved estimated median time to death (2.9 vs. 1.8 years, P = 0.029) in patients with tumour LVSI. This study found an association between effective post-operative epidural analgesia and medium-term benefit on cancer recurrence and survival following oesophageal surgery. A prospective study that controls for disease type, stage and epidural effectiveness is warranted. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    The role of octamer-binding transcription factor 4 (Oct4) has been implicated in the clinical prognosis of various kinds of digestive system cancers, but the results remain controversial. The purpose of this meta-analysis is to assess the potential role of Oct4 as a prognostic marker in digestive system tumors. Relevant articles were retrieved from Pubmed, Web of Science, and Cochrane Library up to July 2016. The software Stata 12.0 was used to analyze the outcomes, including overall survival (OS), disease-free survival, recurrence-free survival, and clinicopathological characteristics. A total of 13 eligible studies with 1538 patients were included. Elevated Oct4 expression was significantly associated with poor OS (pooled hazard ratio [HR] = 2.183, 95% confidence interval [CI]: 1.824-2.612), disease-free survival (pooled HR = 1.973, 95% CI: 1.538-2.532), and recurrence-free survival (pooled HR = 2.209, 95% CI: 1.461-3.338) of digestive system malignancies. Subgroup analyses showed that cancer type, sample size, study quality, and laboratory detection method did not alter the significant prognostic value of Oct4. Additionally, Oct4 expression was found to be an independent predictive factor for OS (HR = 2.068, 95% CI: 1.633-2.619). No significant association was found between Oct4 and clinicopathological features of digestive system malignancies. This study provided evidence of Oct4 and/or its closely related homolog protein as a predictive factor for patients with digestive system cancers. More large-scale clinical studies on the prognostic value of Oct4 are warranted. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    2018-03-01

    Superparamagnetic iron oxide nanoparticles (SPIONs) are tested to identify sentinel lymph nodes (SLNs) to exploit the advantages of targeted pelvic SLN dissection (sPLND), while circumventing the disadvantages of established radioactive labeling. Here we review recent studies about sPLND in prostate cancer (PCa), including the first results of SLN detection using intraprostatic SPION-injection. A recent systematic literature review reveals that the diagnostic accuracy of sPLND is comparable with extended PLND (ePLND). sPLND combined with ePLND achieve better node removal by increasing the number of affected nodes. The first sentinel-based nomogram predicting lymph node invasion is established. A sentinel-nomogram update provides comparative predictions relative to ePLND models. sPLND using a magnetometer and SPIONs as a tracer is successful whenever applied to PCa, and SLN identification using MRI after intraprostatic injection of SPIONs is feasible. SLNs are present in an unexpectedly high number outside the ePLND template. SLN detection outside the ePLND template and the increased diagnostic value of sPLND compared with ePLND supports the individualized extension of PLND using sPLND in PCa. SPION-MRI, combined with a hand-held magnetometer, provides a nonradioactive technique for preoperative and intraoperative SLN localization. Further studies are required to evaluate the effects of sPLND on oncological outcomes.

    Five-year active follow-up of 236 breast cancer patients undergoing radical amputation with subsequent telegammatherapy showed in 21 (8.9%) of the cases development, on the lesion side, of brachial plexitis varying in severity and becoming manifest from 6 to 28 months following completion of complex treatment. The patients presented with the initial and leading symptom of progressively increasing diffuse causalgic pain spreading over the whole arm. Clinical findings corresponded to injury of nerve fiber interlacings in this zone, with distal parts of the extremity selectively affected and dominance of signs from damage to individual nerves. Evidence obtained by a variety of techniques (capillary microscopy, oscillography, skin and axillar thermometry, and the ''white spot'' symptom) indicated formation of a distinct trophovascular syndrome associated with the clinical pattern of plexitis. The complexity of causative factors in development of the pathologic process is pointed out: surgical intervention and postoperative period, direct radiation exposure of the brachial plexus, sympathetic ganglia and vascular bundle, as well as substantial fibrous changes in soft tissues. The treatment administered (pharmacotherapy, exercise therapy, physiotherapy) brought relief in a measure depending on the state of plexitis at the time of diagnosing.

    This study aimed to assess the effects of body mass index (BMI) on survival in cervical cancer patients who had undergone surgery and radiotherapy (RT). We retrospectively reviewed the medical records of 70 cervical cancer patients who underwent surgery and RT from 2007 to 2012. Among them, 40 patients (57.1%) had pelvic lymph node metastases at the time of diagnosis. Sixty-seven patients (95.7%) had received chemotherapy. All patients had undergone surgery and postoperative RT. Median BMI of patients was 22.8 kg/m2 (range, 17.7 to 35.9 kg/m2). The median duration of follow-up was 52.3 months (range, 16 to 107 months). Twenty-four patients (34.3%) showed recurrence. Local failure, regional lymph nodal failure, and distant failure occurred in 4 (5.7%), 6 (8.6%), and 17 (24.3%) patients, respectively. The 5-year actuarial pelvic control rate was 83.4%. The 5-year cancer-specific survival (CSS) and disease-free survival (DFS) rates were 85.1% and 65.0%, respectively. The presence of pelvic lymph node metastases (n = 30) and being overweight or obese (n = 34, BMI ≥ 23 kg/m2) were poor prognostic factors for CSS (p = 0.003 and p = 0.045, respectively). Of these, pelvic lymph node metastasis was an independent prognostic factor (p = 0.030) for CSS. Overweight or obese cervical cancer patients showed poorer survival outcomes than normal weight or underweight patients. Weight control seems to be important in cervical cancer patients to improve clinical outcomes

    Full Text Available Although recent studies have improved understanding of quality of life (QOL outcomes of breast conserving surgery, few have used longitudinal data for more than two time points, and few have examined predictors of QOL over two years. Additionally, the longitudinal data analyses in such studies rarely apply the appropriate statistical methodology to control for censoring and inter-correlations arising from repeated measures obtained from the same patient pool. This study evaluated an internet-based system for measuring longitudinal changes in QOL and developed a cloud-based system for managing patients after breast conserving surgery.This prospective study analyzed 657 breast cancer patients treated at three tertiary academic hospitals. Related hospital personnel such as surgeons and other healthcare professionals were also interviewed to determine the requirements for an effective cloud-based system for surveying QOL in breast cancer patients. All patients completed the SF-36, Quality of Life Questionnaire (QLQ-C30 and its supplementary breast cancer measure (QLQ-BR23 at baseline, 6 months, 1 year, and 2 years postoperatively. The 95% confidence intervals for differences in responsiveness estimates were derived by bootstrap estimation. Scores derived by these instruments were interpreted by generalized estimating equation before and after surgery.All breast cancer surgery patients had significantly improved QLQ-C30 and QLQ-BR23 subscale scores throughout the 2-year follow-up period (p<0.05. During the study period, QOL generally had a negative association with advanced age, high Charlson comorbidity index score, tumor stage III or IV, previous chemotherapy, and long post-operative LOS. Conversely, QOL was positively associated with previous radiotherapy and hormone therapy. Additionally, patients with high scores for preoperative QOL tended to have high scores for QLQ-C30, QLQ-BR23 and SF-36 subscales. Based on the results of usability testing

    The evolution of the surgery of the cancer of cervix has passed for several stages. First the boarding was indisputably vaginal. Thanks to the anestesea, antibioterapia and transfusion was produced a change that has come to our days to the abdominal route with Wertheim Meigs's intervention. From 1987 Dargent he introduced the route laparoscopica, the conservative surgery and the return to the vaginal boarding. Today the robotic surgery is imposed with the Da Vinci. (Author) 16 refs.

    In the Philippines, the treatment of cancers of the limbs has always been by amputation. In recent decades, better understanding of these cancers and advances in the disciplines of cancer medicine have made the saving of these limbs almost routine in better developed countries. Surgeries entail two steps: (1) excision of the tumor and the bone from which the tumor arose, followed by (2) reconstruction of the defect resulting from the excision. Tumor implants, however, are not available locally, and are too costly for the average Filipino patient. Microvascular surgery is limited by the size of the defect it can bridge; and bone cement, not being biologic, can result in greater long term problems. Recently, the option of long bone transplants (aka large-segment allografts) to reconstruct these defects has become available locally. These bones are harvested from both cadaveric and live amputee donors after appropriate consent and medical work-up. After processing at the UP-PGH Tissue and Bone Bank, the bones are sterilized by irradiation at the PNRI(Philippine Nuclear Research Institute), and store in deep freezers until use. In the Philippines, limb saving surgery for bone cancers of the extremities using these large-segment alloografts was introduced in 1993 at the UP-PGH Musculoskeletal Tumor Unit. This paper will present the author's initial 3-year experience with 19 patients whose limbs were saved using bone transplantation. All surgeries were performed by the author and all patients have been personally followed up by the author (follow-up ranging from 6 months to 3-1/2 years). Cases will be presented to show the pre- and intraoperative processing of the irradiated bone; and the patients before and after the operations with emphasis on their improved quality of life and return to function. These results would seem to show that irradiated long bone transplants coupled with skills for limb saving surgery may make amputations a thing of the past for many of our

    Full Text Available PURPOSE: While optimal cytoreduction is the standard of care for advanced ovarian cancer, the related post-operative morbidity has not been clearly documented outside pioneering centers. Indeed most of the studies are monocentric with inclusions over several years inducing heterogeneity in techniques and goals of surgery. We assessed the morbidity of optimal cytoreduction surgery for advanced ovarian cancer within a short inclusion period in 6 referral centers dedicated to achieve complete cytoreduction. PATIENTS AND METHODS: The 30 last optimal debulking surgeries of 6 cancer centers were included. Inclusion criteria included: stage IIIc- IV ovarian cancer and optimal surgery performed at the site of inclusion. All post-operative complications within 30 days of surgery were recorded and graded using the Memorial secondary events grading system. Student-t, Chi2 and non-parametric statistical tests were performed. RESULTS: 180 patients were included. There was no demographic differences between the centers. 63 patients underwent surgery including intestinal resections (58 recto-sigmoid resection, 24 diaphragmatic resections, 17 splenectomies. 61 patients presented complications; One patient died post-operatively. Major (grade 3-5 complications requiring subsequent surgeries occurred in 21 patients (11.5%. 76% of patients with a major complication had undergone an ultraradical surgery (P = 0.004. CONCLUSION: While ultraradical surgery may result in complete resection of peritoneal disease in advanced ovarian cancer, the associated complication rate is not negligible. Patients should be carefully evaluated and the timing of their surgery optimized in order to avoid major complications.

    Full Text Available This study sought to synthesize survival outcomes from trials of laparoscopic and open colorectal cancer surgery, and to determine whether expert acceptance of this technology in the literature has parallel cumulative survival evidence.A systematic review of randomized trials was conducted. The primary outcome was survival, and meta-analysis of time-to-event data was conducted. Expert opinion in the literature (published reviews, guidelines, and textbook chapters on the acceptability of laparoscopic colorectal cancer was graded using a 7-point scale. Pooled survival data were correlated in time with accumulating expert opinion scores.A total of 5,800 citations were screened. Of these, 39 publications pertaining to 23 individual trials were retained. As well, 414 reviews were included (28 guidelines, 30 textbook chapters, 20 systematic reviews, 336 narrative reviews. In total, 5,782 patients were randomized to laparoscopic (n = 3,031 and open (n = 2,751 colorectal surgery. Survival data were presented in 16 publications. Laparoscopic surgery was not inferior to open surgery in terms of overall survival (HR = 0.94, 95% CI 0.80, 1.09. Expert opinion in the literature pertaining to the oncologic acceptability of laparoscopic surgery for colon cancer correlated most closely with the publication of large RCTs in 2002-2004. Although increasingly accepted since 2006, laparoscopic surgery for rectal cancer remained controversial.Laparoscopic surgery for colon cancer is non-inferior to open surgery in terms of overall survival, and has been so since 2004. The majority expert opinion in the literature has considered these two techniques to be equivalent since 2002-2004. Laparoscopic surgery for rectal cancer has been increasingly accepted since 2006, but remains controversial. Knowledge translation efforts in this field appear to have paralleled the accumulation of clinical trial evidence.

    Recent evidences indicate that circulating microRNAs (miRNAs) exhibit aberrant expression in the plasma of patients suffering from cancer compared to normal individuals, suggesting that it may be a useful noninvasion diagnostic method. MiR-21 plays crucial roles in carcinogenesis and can be served as a biomarker for the detection of various cancers. Therefore, the aim of this meta-analysis is to assess the potential role of miR-21 for digestive system cancer. By searching the PubMed, Embase, and Web of Science for publications concerning the diagnostic value of miR-21 for digestive system cancer, total of 23 publications were included in this meta-analysis. Receiver operating characteristic curves (ROC) were used to check the overall test performance. For prognostic meta-analysis, pooled hazard ratios (HRs) of circulating miR-21 for survival were calculated. Totally 23 eligible publications were included in this meta-analysis (15 articles for diagnosis and 8 articles for prognosis). For diagnostic meta-analysis, the summary estimates revealed that the pooled sensitivity and specificity were 0.76 (95% CI = 0.70-0.82) and 0.84 (95% CI = 0.78-0.89). Besides, the area under the summary ROC curve (AUC) is 0.87. For prognostic meta-analysis, the pooled HR of higher miR-21 expression in circulation was 1.94 (95% CI = 0.99-3.82, P = 0.055), which indicated higher miR-21 expression could be likely to predict poorer survival in digestive system cancer. The subgroup analysis implied the higher expression of miR-21 was correlated with worse overall survival in the Asian population in digestive system cancer (HR = 2.41, 95% CI = 1.21-4.77, P = 0.012). The current evidence suggests circulating miR-21 may be suitable to be a diagnostic and prognostic biomarker for digestive system cancer in the Asians.

    The objective of this study was to examine both overall and disease-free survival of patients with advanced stage ovarian cancer after immediate or interval debulking surgery based on residual disease. We performed a retrospective chart review at the Tom Baker Cancer Centre in Calgary, Alberta of patients with pathologically confirmed stage III or IV ovarian cancer, fallopian tube cancer, or primary peritoneal cancer between 2003 and 2007. We collected data on the dates of diagnosis, recurrence, and death; cancer stage and grade, patients' age, surgery performed, and residual disease. One hundred ninety-two patients were included in the final analysis. The optimal debulking rate with immediate surgery was 64.8%, and with interval surgery it was 85.9%. There were improved overall and disease-free survival rates for optimally debulked disease (advanced stage ovarian cancer, the goal of surgery should be resection of disease to microscopic residual at the initial procedure. This results in improved overall survival than lesser degrees of resection. Further studies are required to determine optimal surgical management.

    This study aimed to evaluate the diagnostic yield of preoperative computed tomography (CT) imaging and the validity of surgical intervention based on the clinical decision to perform surgery for lung cancer or suspected lung cancer. We retrospectively evaluated 1755 patients who had undergone pulmonary resection for lung cancer or suspected lung cancer. CT scans were performed on all patients. Surgical intervention to diagnose and treat was based on a medical staff conference evaluation for the suspected lung cancer patients who were pathologically undiagnosed. We evaluated the relation between resected specimens and preoperative CT imaging in detail. A total of 1289 patients were diagnosed with lung cancer by preoperative pathology examination; another 466 were not pathologically diagnosed preoperatively. Among the 1289 patients preoperatively diagnosed with lung cancer, the diagnoses were confirmed postoperatively in 1282. Among the 466 patients preoperatively undiagnosed, 435 were definitively diagnosed with lung cancer, and there were 383 p-stage I disease patients. There were 38 noncancerous patients who underwent surgery with a diagnosis of confirmed or suspected lung cancer. Among the 1755 patients who underwent surgery, 1717 were pathologically confirmed with lung cancer, and the diagnostic yield of preoperative CT imaging was 97.8%. Among the 466 patients who were preoperatively undiagnosed, 435 were compatible with the predicted findings of lung cancer. Diagnostic yields of preoperative CT imaging based on clinical evaluation are sufficiently reliable. Diagnostic surgical intervention was acceptable when the clinical probability of malignancy was high and the malignancy was pathologically undiagnosed. (author)

    High-energy gamma probes have recently become commercially available, developed for 18 F-FDG probe-guided surgery. The radiation received by the staff in the operating room might limit the use of it, but has never been determined. We therefore wanted to measure the absorbed staff doses at operations where patients had received a preoperative injection of 18 F-FDG. Thirty-four patients with different cancers (breast cancer, melanoma, gastrointestinal cancers, respectively) were operated. At every operation the surgeon was monitored with a TLD tablet on his finger of the operating hand and a TLD tablet on the abdomen. The surgeon and anaesthesiologist were also monitored using electronic dosimeters placed in the trousers lining at 25 operations. The dose rate to the surgeon's abdominal wall varied between 7.5-13.2 μSv/h, depending on tumour location. The doses to the anaesthesiologists and the finger doses to the surgeon were much lower. About 350-400 MBq, i.e. ca. eight times higher activities than those used in the present study are supposed to be necessary for guiding surgery. It can be calculated from the body doses measured that a surgeon can perform between 150-260 h of surgery without exceeding permissible limits for professional workers. The radiation load to the operating staff will generally be so small that it does not present any limitation for FDG-guided surgery. However, it is recommended to monitor the surgical staff considering that the surgeon may be exposed to other radiation sources, and since the staff often includes women of child-bearing age.

    Full Text Available Abstract Background Colorectal cancer (CRC is a major source of morbidity and mortality in the elderly population and surgery is often the only definitive management option. The suitability of surgical candidates based on age alone has traditionally been a source of controversy. Surgical resection may be considered detrimental in the elderly solely on the basis of advanced age. Based on recent evidence suggesting that age alone is not a predictor of outcomes, Western societies are increasingly performing definitive procedures on the elderly. Such evidence is not available from our region. We aimed to determine whether age has an independent effect on complications after surgery for colorectal cancer in our population. Methods A retrospective review of all patients who underwent surgery for pathologically confirmed colorectal cancer at Aga Khan University Hospital, Karachi between January 1999 and December 2008 was conducted. Using a cut-off of 70 years, patients were divided into two groups. Patient demographics, tumor characteristics and postoperative complications and 30-day mortality were compared. Multivariate logistic regression analysis was performed with clinically relevant variables to determine whether age had an independent and significant association with the outcome. Results A total of 271 files were reviewed, of which 56 belonged to elderly patients (≥ 70 years. The gender ratio was equal in both groups. Elderly patients had a significantly higher comorbidity status, Charlson score and American society of anesthesiologists (ASA class (all p Conclusion Older patients have more co-morbid conditions and higher ASA scores, but increasing age itself is not independently associated with complications after surgery for CRC. Therefore patient selection should focus on the clinical status and ASA class of the patient rather than age.

    We investigated the efficacy of electroacupuncture in reducing the duration of postoperative ileus and hospital stay after laparoscopic surgery for colorectal cancer. We performed a prospective study of 165 patients undergoing elective laparoscopic surgery for colonic and upper rectal cancer, enrolled from October 2008 to October 2010. Patients were assigned randomly to groups that received electroacupuncture (n = 55) or sham acupuncture (n = 55), once daily from postoperative days 1-4, or no acupuncture (n = 55). The acupoints Zusanli, Sanyinjiao, Hegu, and Zhigou were used. The primary outcome was time to defecation. Secondary outcomes included postoperative analgesic requirement, time to ambulation, and length of hospital stay. Patients who received electroacupuncture had a shorter time to defecation than patients who received no acupuncture (85.9 ± 36.1 vs 122.1 ± 53.5 h; P electroacupuncture also had a shorter time to defecation than patients who received sham acupuncture (85.9 ± 36.1 vs 107.5 ± 46.2 h; P = .007). Electroacupuncture was more effective than no or sham acupuncture in reducing postoperative analgesic requirement and time to ambulation. In multiple linear regression analysis, an absence of complications and electroacupuncture were associated with a shorter duration of postoperative ileus and hospital stay after the surgery. In a clinical trial, electroacupuncture reduced the duration of postoperative ileus, time to ambulation, and postoperative analgesic requirement, compared with no or sham acupuncture, after laparoscopic surgery for colorectal cancer.

    Purpose: Surgery and radiation therapy represent the only curative options for many patients with solid malignancies. However, despite the recommendations of their physicians, some patients refuse these therapies. This study characterized factors associated with refusal of surgical or radiation therapy as well as the impact of refusal of recommended therapy on patients with localized malignancies. Methods and Materials: We used the Surveillance, Epidemiology, and End Results program to identify a population-based sample of 925,127 patients who had diagnoses of 1 of 8 common malignancies for which surgery and/or radiation are believed to confer a survival benefit between 1995 and 2008. Refusal of oncologic therapy, as documented in the SEER database, was the primary outcome measure. Multivariable logistic regression was used to investigate factors associated with refusal. The impact of refusal of therapy on cancer-specific mortality was assessed with Fine and Gray's competing risks regression. Results: In total, 2441 of 692,938 patients (0.4%) refused surgery, and 2113 of 232,189 patients (0.9%) refused radiation, despite the recommendations of their physicians. On multivariable analysis, advancing age, decreasing annual income, nonwhite race, and unmarried status were associated with refusal of surgery, whereas advancing age, decreasing annual income, Asian American race, and unmarried status were associated with refusal of radiation (P<.001 in all cases). Refusal of surgery and radiation were associated with increased estimates of cancer-specific mortality for all malignancies evaluated (hazard ratio [HR], 2.80, 95% confidence interval [CI], 2.59-3.03; P<.001 and HR 1.97 [95% CI, 1.78-2.18]; P<.001, respectively). Conclusions: Nonwhite, less affluent, and unmarried patients are more likely to refuse curative surgical and/or radiation-based oncologic therapy, raising concern that socioeconomic factors may drive some patients to forego potentially life

    This review aims to appraise the role of physiotherapy care in patients submitted to pulmonary surgery, in preoperative, perioperative, and postoperative phases. Pulmonary surgery is the gold standard treatment for patients with lung cancer if it is completely resectable. However, the major impairments and complications induced by surgery are well known. Physiotherapy has been regularly used both in the preparation of the surgical candidates; in their functional recovery in the immediate postoperative period, and in the medium/long term but there is a lack of concise evidence-based recommendations. Therefore, the aim of this review is to appraise the literature about the role of physiotherapy interventions in patients undergoing lung surgery for lung cancer, in preoperative, perioperative, postoperative and maintenance stages, to the recovery and well-being, regardless of the extent of surgical approach. In conclusion, physiotherapy programs should be individually designed, and the goals established according to surgery timings, and according to each subject's needs. It can also be concluded that in the preoperative phase, the main goals are to avoid postoperative pulmonary complications and reduce the length of hospital stay, and the therapeutic targets are respiratory muscle training, bronchial hygiene and exercise training. For the perioperative period, breathing exercises for pulmonary expansion and bronchial hygiene, as well as early mobilization and deambulation, postural correction and shoulder range of motion activities, should be added. Finally, it can be concluded that in the postoperative phase exercise training should be maintained, and adoption of healthy life-style behaviours must be encouraged.

    This multicenter prospective study aimed to assess the utility of dynamic enhanced magnetic resonance imaging (MRI) prior to breast-conserving surgery for breast cancer. The research subjects were drawn from patients with primary early resectable breast cancer treated in the breast disease centers of six three-level hospitals in Beijing from 1 January 2010 to 31 December 2012. The participants were allocated to a breast-conserving surgery group (breast-conserving group) or a total mastectomy group (total mastectomy group). Enhanced MRI was used to measure breast volume, longest diameter of tumor and tumor volume. The correlations between these measurements and those derived from histopathologic findings were assessed. The relationships between the success rate of breast-conserving surgery and MRI- and pathology-based measurement results were statistically analyzed in the breast-conserving group. The study included 461 cases in the total mastectomy group and 195 in the breast-conserving group. Allocation to these groups was based on clinical indications and patient preferences. The cut-off for concurrence between MRI- and pathology-based measurements of the longest diameter of tumor was set at 0.3 cm. In the total mastectomy group, the confidence interval for 95% concurrence of these measurements was 35.41%-44.63%. Correlation coefficients for MRI and histopathology-based measurements of breast volume, tumor volume and tumor volume/breast volume ratio were r = 0.861, 0.569, and 0.600, respectively (all P surgery were 100% and 88.54%, respectively. There were significant correlations between dynamic enhanced MRI- and histopathology-based measurements of the longest diameter of breast lesions, breast and tumor volumes, and breast volume/tumor volume ratios. Preoperative MRI examination improves the success rate of breast-conserving surgery.

    Colorectal cancer, a malignant tumor arising from the colon or rectum, is a common cancer in China, with most patients diagnosed at the advanced stage or locally advanced stage. Large tumor size results in the invasion of adjacent organs and the multiple organ involvement, which poses certain challenges for clinical treatment. When facing advanced stage colorectal cancer, some surgeons do not consider surgery, a reasonable option. However, in fact, multi-disciplinary treatment can achieve relatively good treatment outcomes in patients with advanced stage or locally advanced stage colorectal cancer. Therefore, reasonable surgery should not be hastily abandoned. For patients with large tumors without distant metastases but with multiple organ involvement, directly surgical resection is difficult, therefore, preoperative adjuvant therapy can be considered. The basic principle of surgical treatment is to accomplish maximum protection of organ functions and to perform reasonable regional lymph node dissection on the basis of achieving R0 resection. Common surgical procedures for locally advanced colorectal cancer are as follows: (1)Right-sided colon cancer with duodenal invasion: first, the colon must be freed from three directions, namely the right posterior surface of the colon, the left side of the tumor, and the upper side of the tumor inferior to the pylorus, so as to expose and assess the spatial relationship between the tumor and the duodenum; the actual tumor invasion depth in the duodenum may be shallow. (2) Splenic flexure colon cancer with invasion of the cauda pancreatis and hilum lienis: multivisceral resection must be performed without separating the attachment between the tumor and spleen. The tumor border can be found more easily through manipulations starting from the descending colon. (3) Giant sigmoid colorectal cancer with bladder invasion: invasion usually occurs at the bladder fundus. Therefore, during surgery, the attachment between the rectum and

    Abscess formation in lung cancer after transbronchial biopsy (TBB) is a rare complication with no standard consensus on a coping strategy or prophylaxis. We describe an instructive case of lung cancer which developed into an abscess after TBB. An 80-year-old man with poorly controlled diabetes mellitus underwent TBB for diagnosing a mass lesion in the left upper lobe. The TBB specimen confirmed a diagnosis of lung cancer, and he was scheduled for radical surgery. However, the tumour was revealed to have progressed into an enlarged abscess 24 days after TBB. Prompt use of meropenem failed to relieve the infection, hence we performed emergency left upper lobectomy. Poorly controlled diabetes mellitus was considered to be a risk for the formation of a tumour abscess after TBB. It was difficult to control the infection with conservative treatment using antibiotics; emergency surgical resection was considered to be the safest strategy for recovery.

METHODS: Preoperative and postoperative data were prospectively recorded in 740 patients undergoing elective resection...... for primary colorectal cancer. None of the patients received preoperative or postoperative chemotherapy or radiation therapy. Endpoints were overall survival and disease recurrence in the subgroup of patients operated on with curative intention who also survived the first 30 days after operation. Storage......BACKGROUND: Perioperative blood transfusion and subsequent development of postoperative infectious complications may lead to poor prognosis of patients with colorectal cancer. It has been suggested that the development of postoperative infectious complications may be related to the storage time...

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

    INTRODUCTION An audit of patients presenting with colorectal cancer to our district general hospital during a 2-year period from November 1994 found that 12.1% of cases were diagnosed later than 6 months after initial presentation to a physician. This audit was repeated for a 2-year period from December 2001, to determine whether the introduction of a specialist coloproctology surgery service had led to a reduction in late diagnosis of colorectal cancer. PATIENTS AND METHODS Case notes were reviewed of all patients presenting with colorectal cancer between December 2001 and November 2003. Late diagnosis was defined as diagnosis of colorectal cancer more than 6 months after their first attendance to either their general practitioner or district general hospital. The results were compared with those of the previous study. RESULTS Of a total of 218 patients presenting with colorectal cancer during the study period, 14 (6.4%; 10 men and 4 women) satisfied the criteria for late diagnosis, with the longest delay being 12.5 months. Reasons for late diagnosis were false-negative reporting of barium studies (n = 3), inaccurate tumour biopsy (n = 2), concurrent pathology causing anaemia (n = 4), inappropriate delay in definitive investigation (n = 3), and refusal of investigation by patients (n = 2). CONCLUSIONS There has been a reduction of nearly 50% (12.1% to 6.4%) in the proportion of patients with a late diagnosis of colorectal cancer compared with our previous audit. It is suggested that an important factor in this improvement in diagnosis has been the introduction of a specialist coloproctology surgery service. PMID:17059718

    To analyze the recurrent rate, time of recurrence, type of recurrence and the relationship between recurrence and histopathologic findings after radical gastrectomy for early gastric cancer and evaluate the usefulness of follow up abdominal computed tomography after surgery. We retrospectively evaluated 617 abdominal computed tomographic examinations of 144 patients (101 male, 43 female, mean age, 53 years) who underwent radical subtotal gastrectomy for early gastric cancer between July 1994 and July 1997. Follow-up abdominal CT scans were reviewed by three abdominal radiologists for detection of recurrence of early gastric cancer, and endoscopic and pathologic findings were correlated. We also reviewed the surgical pathologic reports for location, size, cell type and depth of invasion of early gastric cancer and lymph node invasion. We analyzed the recurrent rate, time and type of recurrence, and relationship between recurrence rate and pathologic characteristics of early gastric cancer. The recurrent rate was 4.2% (6/144) during 5-7 years after radical subtotal gastrectomy for early gastric cancer. The recurrence was detected on 2-5 years after operation. The types of recurrence were lymph node metastasis (n=5), liver metastasis (n=4), recurrence in the residual stomach or anastomotic site (n=3), adrenal metastasis (n=1), and lung metastasis (n=1). Relationship between recurrence and location, size, depth of invasion and cell type of early gastric cancer and lymph n
