Abstract:Objective To investigate the efficacy of PD-1 inhibitor combined with Oxaliplatin and 5-fluorouracil (FOLFOX4) chemotherapy regimens in the treatment of advanced gastric cancer. Methods A total of 80 patients with advanced gastric cancer who admitted to the 960th Hospital of the Joint Logistic Support Force of the Chinese People’s Liberation Army from February 2016 to May 2019 were selected as study objects. They were divided into control group and study group, with 40 cases in each group. Control group was treated with FOLFOX4 chemotherapy regimens, and study group was treated with PD-1 inhibitor on the basis of control group. The curative effect, immune function, serum oncology indexes and adverse reactions were compared between two groups. Results The total effective rate of study group was higher than that of control group (P < 0.05). After treatment, carcinoembryonic antigen, carbohydrate antigen (CA) 125, and CA199 in two groups were lower than those before treatment, and study group was lower than control group (P < 0.05). After treatment, the levels of CD3+, CD4+, and CD4+/CD8+ in both groups were lower than before treatment, and CD8+ was higher than before treatment. The levels of CD3+, CD4+, and CD4+/CD8+ in study group were higher than those in control group, and CD8+ was lower than those in control group (P < 0.05). There was no significant difference in the incidence of adverse reaction between two groups (P > 0.05). Conclusion The combination of PD-1 inhibitor and FOLFOX4 chemotherapy regimens in the treatment of advanced gastric cancer have a significant effect, which can prevent tumor proliferation, reduce immunosuppression, and are safe and effective.
