Abstract
Purpose: Prostate cancer is rarely diagnosed in men younger than 40 years of age. At present, the available data show a low rate of cancer detection from prostate-specific antigen (PSA) screening of this group of young men. We analyzed the outcome of prostate biopsy results in patients of this age group with a high PSA.
Materials and Methods: Between October 1997 and August 2008, a total of 81 men less than 40 years of age were referred from the Health Care Promotion Center as the result of elevated PSA levels. Six men with prostatitis were excluded. The remaining 75 men were asymptomatic and had normal findings on the digital rectal examination (DRE) and were selected to have a transrectal ultrasound-guided prostate biopsy for suspected prostate cancer. The patients with sustained high PSA levels underwent repeat biopsies.
Results: The median age of the 75 men was 33 years (range, 26-40 years) and the mean PSA level was 6.57 ng/ml (range, 4.32-13.45 ng/ml). The results of the primary biopsy was 1 (1.3%) case of prostate cancer, 70 cases (93%) with benign tissue, 2 cases (2.6%) with inflammation, and 1 case each (1.3%) with high grade intraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). Of the 10 men who underwent a second biopsy, all had benign findings. Three of the men who underwent a third biopsy all had benign tissue findings.
Conclusions: The prostate cancer detection rate in young men less than 40 years of age with high PSA levels and normal DREs was very low. Repeat biopsy for sustained high PSA levels in young men less than 40 years of age may not be indicated.
