    Abstract:
    BACKGROUND: To determine the local control, survival, and functional outcome of local excision plus postoperative therapy for patients with rectal cancer. METHODS: A total of 39 patients underwent a local excision (2 with snare excision of a T1 polyp and 37 with full-thickness local excision) followed by postoperative radiation therapy +/- 5-FU-based chemotherapy. The median follow-up was 41 months, and 11 patients had positive margins. RESULTS: The 5-year actuarial colostomy-free survival was 87% and overall survival was 70%. Crude local failure increased with T stage: 0% T1, 24% T2, and 25% T3. Of the 8 patients (21%) who developed local failure, 5 underwent salvage APR and were locally controlled. Actuarial local failure at 5 years was 31% for T2 disease and 27% for the total patient group. In the 32 patients with an intact sphincter, 94% had good to excellent sphincter function. CONCLUSION: Although local failure in patients with T2 tumors has increased since our prior report, the survival, sphincter function, and local salvage rates are acceptable. Local excision and postoperative therapy remains a reasonable alternative to APR in selected patients.
