Visceral-to-subcutaneous fat ratio is a possible prognostic factor for type 1 endometrial cancer

BACKGROUND: Associations have been observed between obesity defined by the body mass index (BMI) and the incidence of endometrial cancer. However, the impact of obesity on the prognosis of endometrial cancer is not yet clear. Recently, visceral fat has been considered to have a greater impact on malignant disease in obese patients than subcutaneous fat. In this study, we investigated the association between prognostic factors of type 1 and type 2 endometrial cancer and obesity parameters. METHODS: The impacts of clinical factors on the progression-free survival (PFS) and overall survival (OS) were analyzed retrospectively in 145 primary endometrial cancer patients. The factors included age, BMI, pathological findings, Federation of Gynecology and Obstetrics (FIGO) stage, status of lymph node metastasis, and the amounts of visceral and subcutaneous fat obtained from computed tomography (CT) data. RESULTS: Only the visceral-to-subcutaneous fat ratio (V/S ratio) (cutoff value 0.5) corresponded to a significant difference in OS and PFS in type 1 endometrial cancer (p = 0.0080, p = 0.0053) according to the results of log-rank tests of Kaplan-Meier curves. The COX regression univariate analysis revealed that only the V/S ratio was a significant prognostic factor for PFS, but not OS (p = 0.033 and p = 0.270, respectively). CONCLUSION: A V/S ratio > 0.5 is a possible factor for poor prognosis in type 1 endometrial cancer. Further research is needed to investigate the preventive and therapeutic effects of reducing visceral fat on the prognosis of this type of cancer.
