Local excision of carcinoma of the rectum for cure.

During the past 10 years, we have treated 63 patients with invasive adenocarcinoma of the rectum by full-thickness local excision. Rigid criteria were employed in patient selection. None of the tumors was pedunculated or in situ carcinoma. Of the 63 lesions, 53 were confined to the bowel wall and constitute the basis for this report. Thirty-five lesions penetrated only the submucosa and 18 invaded the muscularis propria. Twenty-four patients underwent full-dose postoperative radiotherapy with minimal complications. Follow-up ranged from 12 to 130 months, with a median of 44 months. Four tumors recurred locally (8%). Of these, two patients apparently have been salvaged by reexcision. One patient died 32 months after abdominoperineal resection of brain metastases (without local tumor). One patient who did not receive close follow-up died of local recurrence. Seven have died of unrelated causes. The 5-year corrected disease-free survival is 90%. Local excision combined with radiotherapy for selected rectal cancers yields a high rate of cure with minimal morbidity and is now our preferred mode of treatment for all patients whose tumors meet our rigid criteria.
