Abstract

Purpose of review

Prostate cancer is the most common noncutaneous malignancy among men in the USA and is most frequently diagnosed through prostate-specific antigen (PSA)-based screening. Nevertheless, PSA testing has become increasingly controversial. In this review, we will present the evidence supporting the role of PSA in prostate cancer screening.

Recent findings

Numerous studies have shown that the risk of current and future prostate cancer is directly related to the serum PSA level. Moreover, increasing PSA levels predict a greater risk of adverse pathologic features and worse disease-specific survival. Substantial epidemiologic evidence has suggested a reduction in advanced disease and improvements in prostate cancer survival rates since the introduction of PSA-based screening. Recently, evidence from a randomized trial further validated that PSA testing reduces both metastatic disease and prostate cancer-specific mortality.

Summary

PSA is a valid marker for prostate cancer and its aggressiveness. Level 1 evidence is now available that PSA-based screening reduces both the rate of metastatic disease and prostate cancer-specific mortality.
