PurposeThe role of local excision in treating rectal cancer patients continues to be controversial. The aim of this study was to evaluate the long-term oncological results of local excision for early rectal adenocarcinomas and review the outcomes of salvage therapy on rectal cancer patients.Materials And MethodsBetween March 1992 and September 2005, 35 consecutive patients with early-stage primary rectal adenocarcinomas were treated by local excision with curative intent. The mean tumor distance from the anal verge was 5 cm (range, 1-10 cm).ResultsThe median follow-up was 66 months (range, 17-161 months). Pathological examination revealed 23 cases of T1 and 12 cases of T2. Recurrence had developed in 10 patients (6 local recurrences, 4 systemic recurrences). Purely extrapelvic recurrence was observed in only two (5.7%) patients. Of the eight recurrent patients with surgical salvage, five survived with no evidence of disease at the time of this analysis. The 5-year local recurrence-free and disease-free survival rates were 79.6% and 67.9%, respectively.ConclusionLocal excision alone of early-staged rectal adenocarcinomas, even in the ideal candidate, is followed by a relatively higher local recurrence rate than previously reported and may not be a valid modality. Either the use of adjuvant therapy with local excision, even in patients with T1 lesions or the use of preoperative therapy followed by local excision has good promise.
