Objective To analyze the status of applying programmed death-1 (PD-1) / programmed death-ligand 1 (PD-L1) inhibitors combined with vascular endothelial growth factor (VEGF) / vascular endothelial growth factor receptor (VEGFR) inhibitors in advanced refractory colorectal cancer. Method The relevant literature on domestic and foreign research in recent years was summarized. Results The discovery of immune checkpoint PD-1/PD-L1 and the clinical application of related drugs had changed the treatment pattern of advanced solid tumors, but PD-1/PD-L1 inhibitors had a poor efficacy in the mismatch repair prodicient tumors, and most advanced colorectal cancer belonged to this type. The combination of PD-1/PD-L1 inhibitors and VEGF/VEGFR inhibitors could enhance the therapeutic effect in the advanced refractory colorectal cancer, and their interaction mechanisms and clinical efficacy were continuously being proven. Conclusions The combination of PD-1/PD-L1 inhibitors and VEGF/VEGFR inhibitors is a promising treatment strategy for advanced refractory colorectal cancer. More studies need to be further clarified its efficacy.
