METHODS - Preoperative serum tT was measured in a cohort of 1009 consecutive Caucasian-European patients (mean age 64.8 years, range 41-84) submitted to RP with ePLND. None of the patients had taken any hormonal neoadjuvant treatment or other hormonal preparations during the previous 12 mo. Serum tT was measured the day before surgery (8–10 am) in all cases. Logistic regression models tested the associations among predictors (eg, prostate specific antigen [PSA], clinical stage, biopsy Gleason score, and tT) and LNI. RESULTS - Median tT was 4.5 ng/ml [mean: 4.5; range: 0.02–13.6]. Hypogonadism was observed in 113 (11.2%) patients. LNI was found in 113 (11.2%) patients, with a mean number of lymph nodes removed of 19.2. Mean serum tT level did not vary in patients with LNI as compared with those without LNI; conversely, hypogonadism was found in a significantly greater rate in pN+ patients (Chi2: 6.98; 30.1% vs 19.4%, p=0.008). UVA? At multivariable logistic regression analysis hypogonadism emerged as an independent predictor of LNI (OR 1.81; p=0.03), along with clinical stage (OR 2.02; p=0.04), biopsy Gleason score (OR 14.81; p<0.001) and PSA levels (OR 1.07; p < 0.001). CONCLUSIONS - The results of this study provide evidence that hypogonadism might serve as an independent predictor of LNI in patients with PCa undergoing ePLND.
