EFFECTIVENESS OF PREOPERATIVE CHEMORADIOTHERAPY AND SPHINCTER PRESERVING SURGERY FOR RECTAL CANCER (T3-T4)
Main Article Content
Abstract
Objective: To evaluate the efficiency of preoperative chemoradiotherapy and sphincter-preserving surgery for patients with locally advanced distal rectal cancer. Patients and methods: Description study of 44 patients with locally advanced distal rectal cancer who had received preoperative chemoradiotherapy and sphincter-preserving surgery between May 2016 and May 2021. Results: According the pathologic examination of rescted specimens in patients who had received neo-adjuvant chemoradiotherapy, complete pathologic response was observed in 9,1%, 52,3% showed near complete pathologic response. The mean disease free survival (DFS) was 45,16±3,51months. DFS rates of 1 year, 2 years and 3 years were respectively 97%, 77,4% and 68,3%. Conclusion: Preoperative chemoradiotherapy and sphincter preserving surgery is the cornerstone and effective treatment in locally advanced distal rectal cancer.
