Objective:This study aimed to investigate clinicopathological responses and oncological outcome in patients receiving short- or long-course chemoradiotherapy (CRT) and to assess the predictive factor for recurrence in each treatment.Methods:A total of 118 rectal cancer patients receiving preoperative CRT were enrolled. Clinicopathological responses and oncological outcome in patients receiving short- or long-course CRT were investigated.Results:Despite there being no significant differences in the prognosis of disease-free survival (DFS) based on TNM stage classification in patients receiving long-course CRT, patients with advanced stage demonstrated poor DFS after short-course CRT. The presence of lymph node metastasis was a predictor of poor DFS in short-course CRT, whereas poor pathological response was a predictor of recurrence in long-course CRT.Conclusions:Distinct predictors of recurrence depending on the CRT course might be needed to discriminate candidates from rectal cancer patients receiving preoperative CRT who might benefit from more intensive adjuvant therapy after surgery.
