Methods:A total of 90 patients with primary gastric cancer who received treatment in Tianyou Hospital Affiliated to Wuhan University of Science & Technology between January 2014 and May 2016 were collected and divided into control group and observation group according to the random number table method, 45 cases in each group. The control group of patients received routine systemic intravenous chemotherapy + surgical treatment, and the observation group of patients received systemic intravenous chemotherapy combined with local arterial perfusion chemoembolization + surgical treatment. Levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were compared between the two groups of patients before and after chemotherapy.Results:Before chemotherapy, the levels of tumor markers and angiogenesis factors in serum as well as the expression of oncogenes and tumor suppressor genes in gastric cancer tissue were not significantly different between the two groups of patients;after chemotherapy, serum CEA, CA724, CA242, AFP, VEGF, Ang-2, COX2 and PD-ECGF levels of observation group were lower than those of control group, andiASPP, p130Cas, ERBB2 and C-myc mRNA expression in gastric cancer tissue were lower than those of control group while GKN1, p16, PTEN, TSPYL5 and merlin mRNA expression in gastric cancer tissue were higher than those of control group.Conclusions: Preoperative systemic intravenous chemotherapy combined with regional arterial perfusion chemoembolization can effectively reduce the malignancy of locally advanced gastric cancer and provide favorable conditions for the operation.展开更多
