[Detection of prostate cancer based on monitoring of prostate-specific antigen in outpatient clinic].

: The study included 320 men with suspected prostate cancer (PC). The mean age was 59 years. The detection rate of prostate cancer depending on PSA level was evaluated. According to the results of histological examination, prostate cancer was detected in 32.8% (105 patients) of cases. The prostate cancer most frequently was diagnosed in patients with PSA levels above 20 ng/ml. Thus, the probability of detection of prostate cancer is directly dependent on the level of PSA. All groups showed signs of prostatic intraepithelial neoplasia (PIN), both low and high degrees, but the direct relationship of identification of PIN depending on PSA level was not established.
