ABSTRACT

Objective To discuss the prostate biopsy results in young men with age less than 50 years and with PSA 4-10 μg/L.Methods From January 2006 to December 2011,22 patients with PSA 4-10 μg/L underwent prostate biopsy for free/total PSA ≤ 0.16 (20 cases) and/or positive digital rectal examination (DRE) (4 cases).The nean age was 43 years (range,24-49 years),the mean PSA level was 7.08 μg/L (range,4.17-9.74 μg/L),the mean free/total PSA level was 0.11 (range,0.03-0.53).Radiologic suspicious lesion was founded in 13 cases.Clinicopathological data from these patients were reviewed.Results The results of the biopsy were 1 (4.5％) case of prostate cancer,2 cases (9.1％) with tuberculosis,9 cases (40.9％) with inflammation,10 cases (45.5％) with benign tissue.In 20 cases with free/total PSA ≤0.16,only 1 case was diagnosed as prostate cancer.In 4 cases with positive DRE,tuberculosis (2 cases) and inflammation (1 case) were diagnosed.Conclusions The prostate cancer detection was rare in young men less than 50 years of age with PSA 4-10 μg/L.The most common cause was prostate hyperplasia with inflammation.
