Abstract

Background/Aims/Objectives: We studied the detection rate of prostate cancer (PCa) among Korean men with a prostate-specific antigen (PSA) level of less than 4.0 ng/mL. Methods: A total of 1,680 men with PSA ≤4 ng/mL had a prostate biopsy from January 2004 to December 2014. The differences in clinical factors were analyzed and their independent predictive implications were evaluated. Results: PCa was diagnosed in 331 (19.6%) and 99 of these 331 cancers (14.9%) had a Gleason score of 7 or higher. The detection rate of PCa increased from 6.67% (≤0.5 ng/mL) to 20.36% (3.01-3.9 ng/mL). There were significant differences in age 65.7 vs. 62.1 years, prostate volume 33.4 vs. 38.2 g, PSA density 0.10 vs. 0.08 ng/mL/mL between men with and without PCa. On multivariable analysis, age and prostate volume were the best independent discriminative parameters. When comparing PCa patients with a Gleason score less than 6 to those with a 7 or higher, patients with a Gleason score 7 or higher were older (67.2 vs. 64.8 years). Conclusions: Even when the PSA level is less than 4 ng/mL, PCas, including high-grade cancers, were detected in a significant number of men. In this group, patients with PCa were older and had a smaller prostate volume and high-grade cancers were detected more frequently in older cancer patients.
