Abstract:〔Abstract〕 Objective To investigate the clinical effect of apatinib combined with CapeOX regimen in the treatment of advanced gastric cancer. Methods A total of 70 patients with advanced gastric cancer diagnosed and treated in Sanmenxia Third People’s Hospital from January 2019 to January 2021 were randomly assigned to a control group and an observation group, with 35 patients in each group. The control group was given CapeOX regimen chemotherapy, and the observation group was given apatinib combined with CapeOX regimen. The tumor remission effect, toxic and side effects, the levels of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) and health survey scale (SF-36) scores before and after treatment were compared between the two groups. Results The total remission rate and disease control rate in the observation group were 82.86 % and 94.29 %, respectively, higher than those 54.29 % and 77.14 % in the control group, with statistical significances (P < 0.05). There was no statistically significant difference in toxicity and side effects between the two groups (P > 0.05). After treatment, the levels of serum CEA and CA199 in the observation group were lower than those in the control group, the differences were statistically significant (P < 0.05). After treatment, the scores of physical function, physical pain, mental health and energy performance in the observation group were higher than those in the control group, and the differences were statistically significant (P < 0.05). Conclusion Apatinib combined with CapeOX Chemotherapy has obvious anti-tumor effect, which can control the disease progression and improve the quality of life of patients with advanced gastric cancer.
