Objective To summarize research progress on programmed death 1 (PD-1) and programmed death-ligand 1 (PD-L1) inhibitors and their combination therapies in colorectal cancer and to provide a new treatment direction for colorectal cancer.Method The relevant literatures on the application of the PD-1/PD-L1 inhibitors in the colorectal cancer in recent years were collected and reviewed.Results The clinical trials of anti-PD-1/PD-L1 signaling pathway antibodies had made some achievements in the colorectal cancer, especially in the patients with high frequency microsatellite instability. And the combination therapy of multiple antibodies and the combination with chemotherapy and targeted therapies were more effective.Conclusion PD-1/PD-L1 inhibitors have some certain curative effects on survival of colorectal cancer with high frequency microsatellite instability, especially combination shows a better effect.
