Abstract
Objective: To assess the association and prognostic value of adipokines (adipocyte-secreted peptide hormones) in renal cell carcinoma (RCC). Materials and methods: Plasma samples from 54 RCC patients and 25 age-matched healthy controls were analyzed for levels of adipokines (adiponectin, leptin, retinol-binding protein 4 [RBP4], and nicotinamide phosphoribosyltransferase [NAMPT]). Baseline characteristics and adipokine levels were compared between patients and controls. The effect of adipokine levels on RCC severity was also investigated. Results: Medians (patients/controls) were body mass index: 24.6/23.5 kg/m2, serum glucose: 111/93 mg/dl, and high-density lipoprotein: 43/53 mg/dl, and significantly differed between the 2 groups. Median levels (patients/controls) of adipokines were adiponectin: 4.36/8.84 ug/ml, leptin: 2.91/2.92 ng/ml, RBP4: 30.27/16.17 ug/ml and NAMPT: 2.26/2.06 ng/ml; adiponectin, RBP4 and NAMPT (but not leptin) were independently associated with RCC in logistic regression models, and only serum NAMPT was significantly associated with RCC severity (T stage). Conclusions: Lower plasma levels of adiponectin, and higher levels of RBP4 and NAMPT, are strongly correlated with RCC, indicating that these adipokines could be used as biomarkers for RCC.
