Abstract

Purpose. The authors sought to evaluate the clinical outcome after preoperative short-course radiotherapy (SCRT) 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 ipovolume, 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.
