Association of Obesity and Surgery Outcomes in Patients with Endometrial Cancer: A Single-Center Analysis

Savas Ozdemir, Gul Ozel Dogan

Abstract: Objective Although obesity can result in high morbidity and mortality in surgical outcomes because of multiple comorbidities, determinants of outcome in obese patients who underwent endometrial cancer surgery remain unclear. The aim of this study is to assess the relationship between body mass index (BMI) and surgical outcomes in obese patients with endometrial cancer. Methods An institutional retrospective review of the demographic details, clinical characteristics, and follow-up data of 142 patients with endometrial cancer who underwent surgery during a 72-month period was performed. The patients were divided into three groups based on their BMI; patients with BMI < 25 were identified as normal weight, patients with BMI between 25 and 30 were accepted as overweight, and those with BMI ≥ 30 kg/m2 were identified as obese. The groups' demographic and clinical variables were compared. Results Of the 142 patients, 42 were in the normal weight group, 55 in the overweight group, and 45 in the obese group. Age, surgical procedures, blood loss, preoperative health status, and metastatic lymph nodes did not show a significant difference between groups. However, surgery time and total lymph nodes were higher in the obese group. (p = 0.02, p = 0.00, and p = 0.00, respectively). Common complications were anemia, fever, intestinal injury, deep vein thrombosis, fascial dehiscence and urinary infection. There was no significant difference according to the complications. Conclusion Our results indicated that higher BMI was significantly associated with a longer duration of endometrial cancer surgery. Minimally invasive surgeries and conventional laparotomy could be performed safely in obese patients. S. O. and G. O. D. designed the study. S. O. and G. O. D. collected the data. S. O. analyzed and interpreted the data. G. O. D. drafted the manuscript. All authors were comprehensively involved in all aspects of the study and in the preparation of the manuscript. All authors have read and approved the final version of the it. Received: 22 May 2022 Accepted: 02 September 2022 Article published online: 29 December 2022 © 2022.
