Prostatic Fatty Acids and Cancer Recurrence after Radical Prostatectomy for Early-Stage Prostate Cancer

Objective: Results from some observational studies suggest that diet and energy balance influence the clinical course of early-stage prostate cancer. To evaluate possible mechanisms, we prospectively examined the relation between prostatic concentrations of fatty acids at diagnosis and cancer recurrence following primary therapy. Methods: Fatty acids were measured by capillary gas chromatography in fresh, non-cancerous prostate tissue collected from 184 men undergoing radical prostatectomy for clinically localized prostate cancer. Their association with risk of biochemical disease recurrence (a rising serum prostate-specific antigen following a disease-free [
