However, their combined effect on gastrointestinal cancers surgery outcomes were less understood. This study aims to integrate both general and central obesity to examine the outcomes of gastric cancer surgery in different obesity patterns. We retrospectively analyzed 248 patients who underwent gastric cancer surgery between 2021 and 2023 in a single institute. The Inbody720 body composition analyzer measured body composition. We evaluated the relationship between obesity patterns – combining BMI with central obesity measures (waist circumference, waist-to-hip ratio, visceral fat area)– and postoperative complications and 30-day readmission. Central-only obesity were more likely to induce fistula (P = 0.025), while non-obesity was more likely to develop postoperative abdominal effusion  \n(P = 0.049) and bleeding (P = 0.042). Central-only obesity was significantly associated with severe postoperative complications after adjustment for hypertension, diabetes, abdominal surgery history, preoperative albumin levels, age, sex, and surgical types. This remains significant even after adjusting for muscle mass. However, we did  \nnot find the same results for significant complications. Regarding 30-day readmission, there are no differences between different patterns of obesity. Central-only obesity is an independent risk factor for severe postoperative complications in gastric cancer, while a high BMI appears to be associated with a lower risk compared to non-obese patients, but not significant postoperative complications. The likelihood of readmission within 30 days post-surgery may not be related to the patient’s pattern of obesity. European Journal of Cancer Prevention 34: 436–444 Copyright © 2024 The Author(s).

Although the incidence and mortality of gastric cancer have declined globally over the past 50 years, it remains the fifth leading cause of cancer-related deaths (Thrift and El-Serag, 2020; Ajani et al., 2022). Holistic therapies for gastric cancer, including chemotherapy, targeted therapies, and immunotherapies, have evolved considerably over the past few years. Forresectable gastric cancer, surgical treatment remains the mainstay (Sexton et al., 2020; Guan et al., 2023). However, postoperative adverse events continue to pose a challenge to surgeons. Meanwhile, the incidence of obesity-related cancer is persistently increasing globally. Obesity-related cancers account for approximately 11.9% in males and  \nSupplemental digital content is available for this article.
