- Abstract: 【Objective】 To investigate the predictive value of visceral fat area （VFA） in patients with gastric cancer after radical gastrectomy. 【Methods】 A retrospective analysis was performed on 195 patients who underwent radical gastrectomy in the Department of General Surgery， The First Affiliated Hospital of Xi’an Jiaotong University from January 2014 to December 2017. CT image data and clinicopathological data within 1 week before surgery were collected. VFA was calculated by software， and the patients were divided into VFA-H group （n=96） and VFA-L group （n=99）. The relationship between VFA in different groups and long-term prognosis was compared. 【Results】 CT examination results showed that VFA value was （111±62） cm2， and BMI was positively correlated with VFA value （r=0.640， P<0.001）. ROC curve showed that VFA was more valuable in predicting the prognosis of gastric cancer （AUC=0.703， P<0.001） and better than BMI. Cox regression analysis of prognostic factors in gastric cancer patients： Univariate analysis showed that age， tumor length， TNM stage and VFA were the influencing factors for prognosis， while multivariate analysis showed that TNM stage III and VFA-L were independent risk factors for prognosis of gastric cancer patients. 【Conclusion】 VFA has a good predictive ability and can be used to evaluate the prognosis of gastric cancer patients after operation.
