摘要: PURPOSE To compare the local recurrence rate and overall survival between patients with circumferential resection margin (CRM) involvement by direct tumor spread a within lymph node. METHODS A total of 776 diagnosed rectal cancer underwent resection. Patients CRM were named group A. node formed B. Patient data, including sex, age, pT, pN, stage I-III versus IV, neoadjuvant radiotherapy, adjuvant chemotherapy, carcinoembryonic antigen, primary location, retrieval, need for abdominoperineal resection, compared both groups. RESULTS In total, 10.5% had involvement. Of these, in 57 cases (7.3%), it was 19 (2.4%) Other types found six patients. With mean follow-up 32.9 months, 18 from (31.5%) one patient B (5.2%) suffered recurrence. Local recurrence-free significantly higher (P = 0.049). (P = 0.037) ( P = 0.049) better survival. CONCLUSION have low risk than spread.
