PURPOSE Resection of colorectal liver metastases (CLM) in selected patients has evolved as the standard of care during the last 20 years. In the absence of prospective randomized clinical trials, a survival benefit has been deduced relative to historical controls based on actuarial data. There is now sufficient follow-up on a significant number of patients(More)
Bevacizumab (bev) is a humanized monoclonal antibody that targets vascular endothelial growth factor (VEGF). Perioperative bev is now commonly used in patients undergoing hepatic resection. Little is known, however, about the safety of perioperative bev use in the setting of hepatic resection. Computerized pharmacy records were used to identify all patients(More)
BACKGROUND The neutrophil-lymphocyte ratio (NLR) has been proposed as an indicator of systemic inflammatory response. Previous findings from small-scale studies revealed conflicting results about its independent prognostic significance with regard to different clinical end points in pancreatic cancer (PC) patients. Therefore, the aim of our study was the(More)
AIMS   To analyse the prognostic impact of mucinous differentiation in colorectal mucinous adenocarcinomas and adenocarcinomas with a mucinous component. METHODS AND RESULTS   A total of 381 tumours were reviewed for mucinous differentiation by two independent pathologists. Mismatch repair status was assessed by immunohistochemistry. Prognostic(More)
Hepatic resection is generally accepted as the only potential for long-term survival in patients with colorectal metastases confined to the liver. Despite an unknown benefit, hepatic resection is playing an increasing role in patients with extensive disease. A retrospective review of a prospectively maintained hepatobiliary surgical database was carried(More)
BACKGROUND Blood vessel invasion has been associated with poor outcome in colorectal cancer (CRC), whereas the prognostic impact of lymphatic invasion is less clear. The authors of this report evaluated venous and lymphatic invasion as potential prognostic indicators in patients with CRC focusing on lymph node-negative patients and compared routine and(More)
OBJECTIVE The aim of this study was to determine the results of liver resection for patients with bilateral hepatic metastases from colorectal cancer. We aimed to assess the evolution of the technical approach over time and correlations with morbidity, mortality, and oncologic outcome. SUMMARY BACKGROUND DATA Although hepatic resection for isolated(More)
BACKGROUND: Even with standardization and increasing experience, laparoscopic cholecystectomy still entails the risk of injury to the bile ducts. The incidence of iatrogenic bile-duct injury is currently estimated at 0.3–0.9%. In spite of the downward trend compared to the historical course, the incidence of iatrogenic bile duct injuries is still higher and(More)
The prognostic significance of tumor necrosis in colorectal cancer is unclear. Our study aimed to analyze the prognostic value of tumor necrosis with respect to progression-free and cancer-specific survival and to relate findings to expression of proteins involved in the control of cancer cell death, such as p53 and bcl-2. A total of 381 colorectal cancer(More)
OBJECTIVES Vertical tumor growth, reflected by T classification, represents the most important prognostic variable in colorectal cancer. Our study aimed to investigate the impact of tumor size, particularly the maximum tumor diameter, on outcome of affected patients. METHODS A total of 381 colorectal cancer specimens were re-evaluated. Tumor size and(More)
