- Abstract: PURPOSE: The aim of this study was to investigate the clinical significance of 7 circulating adipokines according to body mass index (BMI) in Korean men with localized prostate cancer (PCa) undergoing radical prostatectomy (RP). MATERIALS AND METHODS: Sixty-two of 65 prospectively enrolled patients with clinically localized PCa who underwent RP between 2015 and 2016 were evaluated. Patients were classified into 2 groups according to their BMI: non-obese (< 25 kg/m²) and obese (≥25 kg/m²). The adipokines evaluated were interleukin-2, insulin-like growth factor 1 (IGF-1), chemerin, C-X-C motif chemokine 10, adiponectin, leptin, and resistin. Multivariate logistic regression analysis was used to identify the independent predictors of advanced tumor stage. RESULTS: We found that obese patients with PCa who underwent RP had a higher incidence of tumors with a high Gleason score (≥8), pathological T3 (pT3) stage, and positive extraprostatic extension than patients with a normal BMI. Additionally, patients with obesity showed significantly lower serum adiponectin and higher serum leptin levels, but did not show differences in other adipokines. Multivariate analysis demonstrated that IGF-1 (odds ratio [OR]=1.03) was identified as a predictor of advanced tumor stage (≥pT3) in the overall population. However, only leptin remained an independent predictive factor for advanced tumor stage (≥pT3) (OR=1.15) in patients with obesity. CONCLUSIONS: In conclusion, our results indicate that a higher leptin level in obese men can be considered a risk factor for aggressive PCa. This prospective study provides greater insight into the role of circulating adipokines in Korean patients with PCa undergoing RP, particularly in patients with obesity.
