Background: Treatment of rectal cancer with preoperative radiotherapy followed by total mesorectal excision is nowadays the standard treatment. It reduces local recurrences and improves overall survival. However, in patients with T2–3, N0 rectal cancer, the role of preoperative radiotherapy remains controversial. The aim of this study was to review the benefit of radiotherapy in T2 and T3, N0 rectal cancer patients. Methods: Between 1996 and 2003, 103 patients with T2–3, N0 rectal cancer were identified in our prospective database. This study evaluated time to local recurrence, distant metastases and overall survival. Results: Median follow-up was 4.3 years. The 5-year local control rate was 94%. The 5-year overall survival was 65%. The 5-year disease-free survival rate was 82%. Preoperative radiotherapy did not show any statistical differences. Abdominal perineal resection and T3 tumors negatively influenced overall survival (p = 0.02). Advanced age was of significant importance in overall survival. Conclusions: Preoperative radiotherapy does not seem to be of significant importance in patients with T2–3, N0 rectal cancer regarding local recurrence and survival. Since preoperative radiotherapy is associated with short- and long-term morbidity, patients with T2–3, N0 tumors should be identified and treated with surgery alone.
