Safe distal margin resection in patients with low rectal cancer undergoing neoadjuvant chemoradiation
Background: Colorectal carcinoma is the third most common cause of death in Iran. This study was performed in order to determine the appropriate distal clearance margin (DCM) for resection of rectal cancer in patients who undergo neoadjuvant chemoradiotherapy for sphincter preserving procedure. Materials and Methods: This was a cross-sectional study conducted in Shahid Faghihi Hospital of Shira...
متن کاملAdequate length of the surgical distal resection margin in rectal cancer: from the viewpoint of pathological findings.
BACKGROUND Previous studies have not identified how to determine the optimal distal margin in rectal cancer based on histopathological diagnosis. We examined the surgical distal resection margin from a histopathological viewpoint. METHODS We enrolled 629 patients. The type of distal spread was evaluated, and the maximum length of distal spread was measured using a micrometer. RESULTS The fr...
متن کاملPredictors of Margin Status for Rectal Cancer
Among 340 patients, 83% had negative resection margins. In 268 patients with resectable tumours, a significantly higher rate of margin positivity was observed in low rectal tumours (32.2%) as compared with midrectal (3.9%) and high rectal (14.3%) tumours. Among 59 patients with locally advanced rectal cancer treated with preoperative radiation (with or without chemotherapy), 32% with low tumour...
متن کاملDefining the optimal therapy for rectal cancer.
For physicians trained in the United States, postoperative combined modality therapy has become the accepted standard for patients with rectal cancer who are at high risk for locoregional and distant recurrence. In 1990, the results of two randomized trials demonstrating improved survival for postoperative chemotherapy with radiation therapy compared with either surgery alone or with postoperat...
متن کاملMultivisceral resection for locally advanced rectal cancer: adequate length of distal resection margin
PURPOSE Locally advanced rectal cancer may require an intraoperative decision regarding curative multivisceral resection (MVR) of adjacent organs. In bulky tumor cases, ensuring sufficient distal resection margin (DRM) for achievement of oncologic safety is very difficult. This study is designed to evaluate the adequate length of DRM in multiviscerally resected rectal cancer. METHODS A total ...
