ABSTRACT

Objective To investigate the effects of preoperative selective gastric arterial chemoembolization on the tumor vasculature in patients with gastric carcinoma.Methods 40 patients with gastric cancer were divided into two groups(1)gastric arterial influsion(GAI)group;and (2)gastric arterial chemoembolization(GAE)group.The peripheral vein plasma tumor necrosis factor(TNF ?) and thrombomodulin(TM)were determined before radiologic intervention(RI),and1d,3d after R1;and the gastric vein plasma TNF ? and TM were also determined during operation.The curative surgical resection of gastric cancer was performed between 7 and 10 days after treatment.Stomach histological alterations were observed postoperatively.Results Compared with GAI group ,the plasma TNF ? levels increased markedly at all the time points,and gastric vein plasma TM levels decreased siginificantly in GAE group (P
