Prostate-specific antigen levels among cirrhotic patients

The aim of this study was to determine serum prostate-specific antigen (PSA) levels in patients with liver cirrhosis. Between January 1995 and August 2001, 216 men with cirrhosis were evaluated. The extent of their liver disease was classified according to the Child-Pugh classification. Serum PSA levels were measured with the Hybritech Tandem-R RIA method and matched with age-related reference PSA levels. Digital rectal examination (DRE) was performed in all patients. Patients with elevated PSA levels and/or abnormal DRE were recommended to undergo further assessment including transrectal ultrasonography (TRUS) and biopsy performed by an urologist. Two hundred and sixteen men (mean age 54.09 +/- 9.09 years, range 25-76) with cirrhosis were examined. Their mean PSA value was 0.57 +/- 0.84 ng/mL and tended to be lower than in the normal population. The degree of PSA decrease was found to parallel the severity of the liver disease (p=0.002). The mean serum PSA level increased with each age decade in a statistically significant manner (p
