Effect of Preoperative Regional IntraArterial Infusion Chemotherapy on the Prognosis of Advanced Gastric Cancer

ObjectiveTo evaluate the effect of preoperative regional intraarterial infusion chemotherapy on the prognosis of advanced gastric cancer. MethodsThe clinical data of 80 patients who underwent curative resection for advanced gastric cancers were summarized.Among them,33 patients carried out preoperative regional intraarterial infusion chemotherapy were as the interventional chemotherapy group,and the remaining 47 patients were the control group.Eleven factors including clinical and pathological data,treatment procedures and molecular biological makers that contributed to the longterm survival rate were analyzed by Cox multivariate regression analysis.ResultsThe 5year survival rate of the interventional group was 59.3%,and the control group 47.6%.There was significant difference between two groups (P＜0.05).Multivariate regression analysis revealed that the preoperative regional intraarterial infusion chemotherapy was one of the independent factors affecting the longterm survival of patients with advanced gastric cancers.ConclusionThe preoperative regional intraarterial infusion chemotherapy has important value for improving the prognosis of gastric cancer.
