Abstract
To evaluate the efficacy of preoperative radiotherapy alone or combine with chemotherapy. Between 1975 to 1997, 318 patients with locally advanced rectal adenocarcinomas were treated with preoperative radiation therapy. Between 1991 and 1997, approximately 60% of patients received fluorouracil (5-FU)-based adjuvant chemotherapy. Patients treated since 1991 had improved downstaging compared with those treated prior to 1991. Patients treated between 1991 and 1997 were also more likely to undergo a sphincter preserving surgical procedure. Preoperative chemoradiation probably results in improved downstaging and survival compared with preoperative irradiation alone.
