Abstract:Objective: To evaluate the efficacy and safety of carrellizumab combined with anti-angiogenic agents in the treatment of metastatic MSS colorectal cancer. Methods: A total of 40 colorectal patients with metastatic MSS were enrolled in the radiotherapy Department of Tangshan People's Hospital from June 2021 to June 2022, who received third-line treatment with carrilizumab combined with anti-angiogenic agents (fuquitinib/regorafenib) or single-agent anti-angiogenic agents (fuquitinib/regorafenib) (20 in the combination group and 20 in the monotherapy group). Overall survival (OS), disease control rate (DCR) and objective response rate (ORR) of the two groups were evaluated, and the incidence of adverse events in the two groups were statistically analyzed. Results: Compared with the monotherapy group, there was no significant difference in the general clinical data of the combined group. The median OS in the combination and monotherapy groups was 11 and 7.5 months, DCR was 85% and 60%, and ORR was 30% and 10%, respectively. The incidence of adverse events in the combination group and the monotherapy group was 95% and 90%, respectively. Most of the adverse events were grade 1-2, and the incidence of serious adverse events (≥ grade 3) was 15% and 10%, respectively, without grade 4 adverse events. The incidence of capillaries in combination group was higher than that in monotherapy group. Conclusion: The combination group has improved benefit for patients with OS, but the difference is not statistically significant compared with the monotherapy group. Immunotherapy combined with anti-angiogenic drugs is a promising strategy, and the combination of the two can improve the survival benefits of patients, showing better anti-tumor activity and high safety in the treatment of advanced metastatic colorectal cancer, providing an important basis for the development of immunotargeted therapy for CRC.
