Neoadjuvant Oxaliplatin and Capecitabine and Bevacizumab without Radiotherapy for Poor-risk Rectal Cancer: N-SOG 03 Phase II Trial

Abstract

Neoadjuvant oxaliplatin and capecitabine plus bevacizumab for poor-risk rectal cancer caused a high rate of anastomotic leakage and experienced a case with perforation during chemotherapy, both of which were bevacizumab-related toxicity. Although the short-term results with the completion rate of 84.4% and the pathological complete response rate of 13.3% were satisfactory, we have to reconsider the necessity of bevacizumab in neoadjuvant chemotherapy (UMIN number, 000003507).
