In Western countries, the standard treatment for locally advanced rectal cancer is preoperative chemoradiotherapy followed by total mesorectal excision. On the other hand, in Japan, treatment results without radiotherapy are by no means inferior; therefore, extrapolation of results of preoperative treatment in Western countries to Japan is controversial. We consider that survival may be improved by preoperative treatment with new anticancer agents as they are expected not only to decrease the local recurrence rate but also to prevent distant metastases. We are conducting a multicentre Phase II study to evaluate the safety and efficacy of neoadjuvant chemotherapy using XELOX plus bevacizumab without radiotherapy in patients with locally advanced rectal cancer. The primary endpoint of the study is treatment compliance. Secondary endpoints are overall survival, disease-free survival, local recurrence-free survival, objective response rate, R0 resection rate and adverse events. Thirty patients are required for this study.
