Abstract: OBJECTIVE: To analyse the association of prostate cancer (PCa) Gleason score evaluated upon prostate biopsy with clinical PSA values, total and free testosterone (TT and FT, respectively) levels measured prior to biopsy. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Urology, Sultan Abdulhamid Han Education and Research Hospital, from July to December 2019. METHODOLOGY: A total of 85 patients were included and classified into non-PCa (group 1) and PCa (group 2) groups according the results of prostate biopsy pathology. Age, digital rectal examination (DRE) findings; prostate volume (PV); free/total prostate specific antigen (PSA) ratio (f/tPSA); PSA density (PSA-D) and total PSA (tPSA), free PSA (fPSA), TT and FT levels of the two groups were evaluated. Associations of the ISUP grade of patients in group 2 with age, DRE findings for PCa; PV; PSA-D; f/tPSA and tPSA, fPSA, TT and FT levels were analysed. RESULTS: Mean patient age was 63.00 (57.50-70.00) years. Mean age, significant DRE findings for PCa, tPSA levels and PSA-D were significantly higher in group 2 (p <0.05), whereas PV was significantly higher in group 1 (p <0.05). The ISUP grade of patients in group 2 was significantly and positively correlated with age and tPSA levels (p <0.05). ISUP grade was significantly and positively correlated with significant DRE findings for PCa (p <0.05). However, ISUP grade was negatively correlated with PV and f/tPSA (p <0.05). No significant difference was observed between the two groups in terms of TT and FT levels (p >0.05). CONCLUSION: TT and FT levels evaluated before prostate biopsy did not provide any additional benefit in predicting Gleason score grade before biopsy. Key Words: Prostate biopsy, prostate cancer, ISUP grade, Gleason score, total testosterone, free testosterone.
