Abstract
Background: The aim of this study was to determine the prognostic role of obesity on oncological outcomes, surgical complications, and postoperative morbidity of patients with early-stage cervical cancer. Methods: Between 2000 and 2016, we enrolled 500 patients with early-stage cervical cancer who underwent radical hysterectomy with pelvic node dissection (RHND) at Songklanagarind Hospital. For analysis, patients were divided based on their body mass index (BMI) into under-normal weight (<25 kg/m<sup>2</sup>), overweight (25–29.99 kg/m<sup>2</sup>), and obese (≥30 kg/m<sup>2</sup>) groups. Results: The median age was 47 years, and the median BMI was 24.3 kg/m<sup>2</sup> (25% quartile, 22.0 kg/m<sup>2</sup>; 75% quartile, 27.4 kg/m<sup>2</sup>). Patients in the obese and overweight groups were more likely to have comorbidities and adenocarcinoma than patients in the under-normal weight group. The median operative time (OT) was significantly longer in the obese and overweight groups than in the under-normal weight group. The 5-year recurrence-free survival (RFS) of the under-normal weight, overweight, and obese groups was 87.5, 86.2, and 97.6%, respectively, and the 5-year overall survival (OS) times were 95.8, 97.8, and 100%, respectively. There were no significant differences in RFS or OS among the 3 weight groups. Multivariate analysis did not identify BMI as a prognostic factor for RFS and OS. Conclusions: A high BMI was not associated with increased surgical complications or postoperative morbidity; furthermore, it was not associated with the prognosis of patients with early-stage cervical cancer after RHND. However, it was associated with adenocarcinoma and longer OT.
