Abstract
- Objective: Metabolic syndrome (MetS) is associated with an increased risk of finding prostate cancer overall and high-grade disease on biopsy. This study sought to determine if MetS is associated with adverse final pathology and risk of overall recurrence in men undergoing radical prostatectomy (RP).<br />Methods: Men undergoing RP (2004-2013) were identified using our prospectively maintained institutional database. MetS was defined by ≥3 of 5 components (obesity, dysglycemia, hypertension, low high-density lipoprotein-cholesterol, and high triglycerides). Multivariable logistic regression models were created for prostate cancer grade and stage on final pathology. Kaplan-Meier and multivariable Cox regression analyses were performed to model overall recurrence, defined by biochemical recurrence (postoperative serum prostate-specific antigen ≥0.2 ng/mL) or use of salvage therapies.<br />Results: Of 1939 men, 439 (22.6%) had MetS. MetS (≥3 vs. 0 components) was associated with an increased odds of Gleason 8-10 disease (odds ratio [OR] = 2.49, 95% confidence interval [CI] = 1.32-4.67, P = .005) and extraprostatic disease (OR = 1.35, 95% CI = 1.02-1.80, P = .04). Decreased use of nerve-sparing in men with MetS was noted. In unadjusted analyses, MetS was associated with a significantly increased risk of receiving salvage therapy (hazard ratio [HR] = 1.38, 95% CI = 1.04-1.83, P = .03) and a near-significant increased overall recurrence risk (HR = 1.20, 95% CI = 0.94-1.53, P = .15). These associations were attenuated upon adjusting for disease-specific parameters (salvage therapy: HR = 1.03, 95% CI = 0.76-1.40, P = .87; overall recurrence: HR = 0.94, 95% CI = 0.72-1.21, P = .62).<br />Conclusion: MetS is associated with an increased odds of extraprostatic and high-grade disease on final RP pathology, which appears to drive an increased risk of needing salvage therapy after RP. However, with more aggressive resection, differences in failure-free outcomes were attenuated, suggesting that men with MetS should not be precluded from RP.<br /> (Copyright © 2016 Elsevier Inc.
