mFOLFOX6 Chemotherapy With Apatinib as Postoperative Treatment in Stage IIIB or IIIC Colorectal Cancer

This study will focus on postoperative patients of stage IIIB or stage IIIC colorectal cancer. These patients will start to accept chemotherapy in 3-4 weeks after operation, these patients were randomly divided into two groups, one group will accept adjuvant chemotherapy of mFOLFOX6; another group will use mFOLFOX6 combined with apatinib. The efficacy and safety of adjuvant chemotherapy will be compared between the two groups. Disease-free survival, overall survival, incidence of adverse reaction of chemotherapy and postoperative quality of life will be recorded.
