ABSTRACT
PURPOSE: Testosterone is essential for the prostate gland's normal growth and development and is also a possible risk factor for prostate cancer. This study's aim was to determine the significance of serum testosterone for prostate-specific antigen (PSA) elevation and prostate cancer prediction in high-risk men. MATERIALS AND METHODS: The study included 120 patients with PSA >10 ng/ml who underwent a transrectal-prostate biopsy. Serum testosterone, prostate volume, and PSA density (PSAD) were checked in all patients. Patients were divided into two groups, patients with and those without prostate cancer; and testosterone-related factors, prostate volume, PSA, PSAD, age, prostate cancer prediction rate, and cancer aggressiveness were evaluated. RESULTS: Thirty-five patients (30.2%) were confirmed as having prostate cancer. The average serum testosterone level in patients without and in those with prostate cancer was 452.25+/-154.62 ng/dl and 458.10+/-158.84 ng/dl, respectively; average PSA was 17.58+/-9.02 ng/ml and 18.62+/-6.53 ng/ml, respectively; and average age was 69.02+/-7.52 years and 70.69+/-7.02 years, respectively (p>0.05). Hypogonadal and eugonadal patients showed no significant difference in cancer prevalence (30.3% vs. 32.0%, respectively). The testosterone level did not differ significantly in patients with and those without prostate cancer in either hypogonadal or eugonadal men (p>0.05). Serum testosterone showed no correlation with PSA, PSAD, or age in either group (p>0.05) and was unrelated to prostate cancer risk or aggressiveness (p>0.05). CONCLUSIONS: In our study's results, serum testosterone at the time of diagnosis was unrelated to PSA elevation, prostate cancer risk, and aggressiveness.
