【Abstract】 Objective To investigate the prognostic value of abdominal visceral fat area for the patients underwent radical gastric cancer after resection. Methods A total of 263 patients who underwent radical resection of gastric cancer in our hospital from January 2015 to December 2016 were enrolled, and the area of visceral fat (VFA) was detected. The patients were divided into high body mass index (BMI) and normal BMI, and divided into high VFA and low VFA groups. The clinical and pathological data, shortterm efficacy and longterm efficacy of patients were compared between two groups. Univariate and multivariate analysis were used to test the independent factor of the prognosis of patients.Results There were 121 patients in the high VFA group and 66 in the high BMI group. The patients in the BMI group had high blood pressure and diabetes, long operation time, high blood loss during operation, and few patients undergoing laparoscopic surgery(P＜0.05). No difference was found in tumor size, stage, differentiation and overall survival in the two BMI groups( P＞0.05). In the high VFA group, more patients had hypertensive and larger tumor, higher stage, longer operation time, more blood loss, smaller number of detected lymph nodes after operation, more IIIA or above complications after surgery. And the patients in the higher VFA groups had few patients with laparoscopic surgery and shorter overall survival time, P＜0.05. Univariate analysis of overall survival of patients found that VFA is a risk factor for prognosis in patients undergoing radical resection of gastric cancer. Conclusion Abdominal visceral fat area can be used as a prognostic indicator for postoperative patients with radical gastric cancer resection.
