Abstract
The surgical treatment of rectal cancer of the middle third remains controversial. We treated 30 consecutive patients with preoperative radiotherapy (45 Gy) and low anterior resection. Anastomoses were performed with a stapler. Intraoperative frozen-section examination of the rectal margin established that it was free of tumor. Two patients died of surgery-related causes. Median follow-up of the remaining patients is now 52 months (range: 26 to 76 months). Eight patients had recurrences documented at surgical re-exploration: two local (pelvic) only, three local and distant, and two distant only. Local recurrences happened despite a frozen-section examination of the rectal margin negative for tumor. Six of the eight patients who experienced a recurrence have died of disease progression. Distant metastases were found in six other patients during follow-up; they subsequently died. Thus, our therapeutic approach was not associated with decreases in local or overall recurrences.
