BACKGROUND: It is well known that there is a link between obesity and oncogenesis in many sites, including the kidney. Adiposopathy is characterized by an excessive accumulation of adipose tissue, principally visceral, which can lead to adipocyte and adipose tissue-related disorder, promoting metabolic syndrome. Visceral adipocytes secrete growth factors, proinflammatory cytokines and adipokines, regarded as mediating factors associated with the oncogenesis of obesity-related tumors. In this study, we evaluate the relationship between visceral adipose tissue (VAT) and non-clear cell renal cell carcinoma (nccRCC) in male patients.METHODS: In this retrospective study, two groups were included: nccRCC group and control group. Total adipose tissue (TAT) area, VAT area and subcutaneous adipose tissue (SAT) area were measured in both groups. VAT/SAT ratio was subsequently calculated.RESULTS: Statistically significant differences between the two groups were found in TAT area (p = 0.05), VAT area (p < 0.01) and VAT/SAT ratio (p < 0.05), while no significant difference was found in SAT area.CONCLUSIONS: This study demonstrates an increased visceral adipose tissue in male patients with nccRCC.

Abstract

BACKGROUND: It is well known that there is a link between obesity and oncogenesis in many sites, including the kidney. Adiposopathy is characterized by an excessive accumulation of adipose tissue, principally visceral, which can lead to adipocyte and adipose tissue-related disorder, promoting metabolic syndrome. Visceral adipocytes secrete growth factors, proinflammatory cytokines and adipokines, regarded as mediating factors associated with the oncogenesis of obesity-related tumors. In this study, we evaluate the relationship between visceral adipose tissue (VAT) and non-clear cell renal cell carcinoma (nccRCC) in male patients.METHODS: In this retrospective study, two groups were included: nccRCC group and control group. Total adipose tissue (TAT) area, VAT area and subcutaneous adipose tissue (SAT) area were measured in both groups. VAT/SAT ratio was subsequently calculated.RESULTS: Statistically significant differences between the two groups were found in TAT area (p = 0.05), VAT area (p < 0.01) and VAT/SAT ratio (p < 0.05), while no significant difference was found in SAT area.CONCLUSIONS: This study demonstrates an increased visceral adipose tissue in male patients with nccRCC.
