PURPOSE: The authors sought to evaluate the clinical outcome after preoperative short-course radiotherapy (SC-RT) for locally advanced resectable rectal cancer in terms of local control (LC) and quality of life (QoL). MATERIALS AND METHODS: Patients with locally advanced rectal cancer enrolled between 1997 and 2008 in an observational study of preoperative SC-RT were analysed. The treatment algorithm was neo-adjuvant chemotherapy (CT) administered for four cycles, followed by preoperative SC-RT administered 1 week after chemotherapy completion, delivering 20 Gy in five fractions over 1 week. Immediately in the following week surgery was performed. The adjuvant 5-FU-based CT was planned for pathological stage UICC≥II. LC, overall survival (OS), disease-free survival (DFS), early and late complications (RTOG scale) were analysed. All patients completed the EORTC QoL (C-30 and C-38), Faecal Incontinence QoL, and International Index of Erectile Function questionnaires (IIEF). RESULTS: A total of 67 patients were analysed. Chemotherapy and radiotherapy were well tolerated. At the pathological analysis, stable disease was obtained in 24 patients (36%), reduction of disease stage in 34 patients (50.7%), and progression in nine cases (13.3%). Adjuvant chemotherapy was indicated in 21 patients. Two locoregional recurrences, both within the radiotherapy volume, were observed, resulting in a 5-year LC of 97%. The 5-year DFS was 84%, with mean time to systemic progression of 24 months. After a mean follow-up of 114 months, the 5-year OS rate was 67%. Late toxicity >grade II was observed in 9% of patients. High anterior resection (AR) patients had significantly better scores than low AR or abdomino-perineal resection (APR). A total of 89% of the patients treated with conservative surgery had regular anal sphincter function. In male patients undergoing AR or APR, erectile dysfunction was found in 47% and 75% of the cases, respectively. CONCLUSIONS: Preoperative SC-RT combined with chemotherapy for locally advanced resectable rectal cancers was well tolerated. This treatment resulted in favourable LC, OS, low rates of toxicity and satisfying QoL.
