Obesity and hypogonadism are associated with an increased risk of predominant Gleason 4 pattern on radical prostatectomy specimen.

PURPOSE - To compare histological features of prostate cancer according to both obesity, defined by a body mass index (BMI) ≥30 kg/m2, and androgenic status in patients who underwent radical prostatectomy.

METHODS - Between March 2007 and September 2013, clinical, pathological and biological data were prospectively collected for patients referred for radical prostatectomy in a single European center. Preoperative total testosterone (TT) and bioavailable testosterone (bioT) serum determinations were performed. The threshold for hypogonadism was set at TT

RESULTS - A total of 937 consecutive patients were included. One hundred and thirty-five filled the criterion for obesity (14.4%), out of which 42 had TT

CONCLUSIONS - Both obesity and hypogonadism are independent risk factors for PrdGP4 in patients who underwent radical prostatectomy and should be taken into account in localized prostate cancer management, to improve the therapeutic choice, especially when prostate sparing approach is considered.
