Popis: OBJECTIVE The objective of this study was to evaluate the impact of body mass index (BMI) on overall survival, freedom from distant metastases, rates of therapeutic intervention (TI), and quality of life (QOL) in active surveillance (AS) prostate cancer patients. MATERIALS AND METHODS Three hundred forty consecutive, prospectively evaluated AS patients underwent a staging transperineal template-guided mapping biopsy before AS enrollment and were stratified by BMI ( 35 kg/m2). Evaluated outcomes included overall survival, freedom from distant metastases, TI, QOL to include urinary, bowel, sexual function and depression and serial postvoid residual urine measurements. The relationship between BMI and anterior prostate cancer distribution was evaluated. Repeat biopsy was based on prostate specific antigen kinetics, abnormal digital rectal examination and patient preference. RESULTS Of the 340 patients, 323 (95%) were Gleason 3+3 and 17 patients (5.0%) were Gleason 3+4. The median follow-up was 5.2 years (range: 1 to 14 y). At 10 years, TI was instituted in 4.7%, 2.2%, 9.5%, and 25.0% of patients in BMI cohorts
