Purpose: The study aimed to evaluate associations of basal levels of total testosterone (TT) with tumor upgrading to high risk disease in low-intermediate risk prostate cancer (PCA). Materials and Methods: We retrospectively evaluated the records of 135 patients undergoing radical prostatectomy. Evaluated factors included age, body mass index, prostate specific antigen (PSA), TT, prostate volume, PSA density (PSAD), proportion of biopsy positive cores (P+), clinical tumor stage, and biopsy grading system (1 or 2). Factors associating with tumor upgrading were investigated by the multivariate logistic regression analysis. Results: Tumor upgrading rate to high risk disease was 8.9%. TT, PSA, and PSAD were associated with tumor upgrading. On multivariate analysis, independent factors predicting tumor upgrading were PSA (OR 1.324; p = 0.001) and TT (OR 1.005; p = 0.015). Basal TT was dichotomized up to the third quartile (TT > q3) vs. TT ≤ q3 (426.0 ng/dL). The assessed tumor upgrading risk model showed that TT dichotomized to third quartile (TT > q3 vs. TT ≤ q3) stratified the risk of tumor upgrading (OR 6.577; p = 0.010) along increasing levels of PSA (OR 1.3; p < 0.0001). Conclusions: Low and intermediate risk PCA patients show a not negligible risk of tumor upgrading to high risk disease. In this particular subset of patients, basal levels of TT stratify the risk of tumor upgrading.

Abstract

Purpose: The study aimed to evaluate associations of basal levels of total testosterone (TT) with tumor upgrading to high risk disease in low-intermediate risk prostate cancer (PCA). Materials and Methods: We retrospectively evaluated the records of 135 patients undergoing radical prostatectomy. Evaluated factors included age, body mass index, prostate specific antigen (PSA), TT, prostate volume, PSA density (PSAD), proportion of biopsy positive cores (P+), clinical tumor stage, and biopsy grading system (1 or 2). Factors associating with tumor upgrading were investigated by the multivariate logistic regression analysis. Results: Tumor upgrading rate to high risk disease was 8.9%. TT, PSA, and PSAD were associated with tumor upgrading. On multivariate analysis, independent factors predicting tumor upgrading were PSA (OR 1.324; p = 0.001) and TT (OR 1.005; p = 0.015). Basal TT was dichotomized up to the third quartile (TT > q3) vs. TT ≤ q3 (426.0 ng/dL). The assessed tumor upgrading risk model showed that TT dichotomized to third quartile (TT > q3 vs. TT ≤ q3) stratified the risk of tumor upgrading (OR 6.577; p = 0.010) along increasing levels of PSA (OR 1.3; p < 0.0001). Conclusions: Low and intermediate risk PCA patients show a not negligible risk of tumor upgrading to high risk disease. In this particular subset of patients, basal levels of TT stratify the risk of tumor upgrading.
