BACKGROUND AND OBJECTIVES: The aim of this retrospective study is to evaluate the results of local excision (LE) for rectal cancer for curative purposes.
METHODS: From 1969 to December 1997, a total of 456 operations were performed for surgical treatment of rectal carcinoma (262 males and 194 females, mean age 66 years). Twenty patients (4.1%) underwent LE (7 males and 13 females, median age 65 years). Patients were selected for LE if they met the following criteria during preoperative staging: tumors staged as T1-T2,N0,M0, grading G1 or G2, and accessible location. Types of LE performed were: 13 transanal excisions (Francillon's technique), 2 Mason surgeries, 2 endoscopic excisions, and 3 transanal endoscopic microsurgeries.
RESULTS: There was no in-hospital mortality among LE patients. Thirteen tumors were T1 and 7 were T2; all 20 were adenocarcinoma, 14 G1 and 6 G2. There was no specific morbidity, and aspecific morbidity was minimal (5%). There were no local recurrences, but 2 patients (10%) had secondary lesions. Five-year overall survival following LE was 87.4%. Comparing T1 and T2 tumors treated with abdominoperineal resection (APR) and SSR (17 T1 and 42 T2, all adenocarcinoma), in-hospital mortality and specific morbidity were respectively 1.7% (P = 0.55) and 28% (P = 0.007). There were 5 (8.5%) local recurrences (P = 0.17) and 6 (10.2%) metastatic lesions. Five-year overall survival was similar to LE (88.3%; P = 0.76).
CONCLUSIONS: LE for rectal carcinoma might only be successfully performed in selected patients with correct preoperative staging. In the LE cases reported five-year overall survival, local recurrence, and in-hospital mortality were similar to APR and SSR, while there was a statistically significant difference following LE in terms of specific morbidity.
