[Local resection in treatment of rectal tumors]

We treated 160 patients (96 males, 64 females) with a mean age of 66 +/- 12 years. 63 patients presented adenomas (AD) and 97 adenocarcinomas (ADC). In the ADC group 32 patients received preoperative chemoradiation (RT + CT), and 15 postoperative RT. In 7 patients with RT + CT the tumor disappeared. No hospital mortality was recorded. Morbidity was observed in 13% of AD group and 18% of ADC group. Hospital stay was less than 7 days for 72% of patients. Stages were: 10 pTis, 40 pT1, 29 pT2, 18 pT3. Recurrence was observed in 7 (11%) of AD and 23/97 ADC (24%). 0 pTis, 12% pT1, 24% pT2, 61% pT3. No patient with RT + CT and negative margins had recurrence with a minimum follow-up of 2 years (11 patients). Five-year cumulative survival was 100% for pTis, 92% for pT1, 75% for pT2 and 69% for pT3.
