Core Tip

Core Tip: This manuscript addresses to evaluate the effectiveness and safety of chemotherapy combined with bevacizumab with or without anti-programmed death 1 immunotherapy as the second-line regimen for microsatellite stable metastatic colorectal cancer. As there is currently no clinical data on the second-line treatment of advanced colorectal cancer with the combination of immunotherapy, anti-angiogenic drugs, and anti-programmed death 1 immunotherapy, we conducted a multicenter retrospective cohort clinical study to explore the safety and efficacy of this triplet therapy in second-line treatment of advanced colorectal cancer patients.
