Abstract
BackgroundMetabolic syndrome (MetS) and gastric cancer are age-related diseases, and their incidence rates have risen in past decades. However, few studies have examined the relationship between MetS and the prognosis of elderly patients who underwent radical gastrectomy, and the conclusions remain controversial. MethodsWe conducted a prospective study of elderly patients who underwent radical gastrectomy for gastric cancer from August 2014 to February 2018. MetS was defined based on visceral fat area (VFA) instead of BMI or waist circumference. Receiver operating characteristic curve analysis was used to determine the cutoff values for VFA. ResultsA total of 585 patients were included in this study. The optimal cutoff values for VFA were 96.1 cm2 for men and 105.2 cm2 for women, and 212 patients were diagnosed with MetS. The patients with MetS suffered significantly more postoperative complications than those without MetS (37.3% versus 21.4%, P < 0.001). The multivariable logistic regression analysis demonstrated that MetS (OR 2.923, P < 0.001), BMI < 18.5 kg/m2 (OR 2.086, P = 0.045), cardiac tumor (OR 1.865, P = 0.013), and Nutritional Risk Screening 2002 scores ≥ 3 (OR 1.654, P = 0.015) were independent risk factors for postoperative complications. During a median follow-up period of 56.4 months, the MetS group and the non-MetS group had comparable overall survival and disease-specific survival. ConclusionsMetS was an independent risk factor for complications of the elderly patients after radical gastrectomy, but had no influence on long-term survival.
