Özet
Objectives: In this study, we aimed to determine whether the prostate-specific antigen level is a reliable marker of prostate cancer in patients with hepatic insufficiency, based on evaluation of alterations in serum prostate-specific antigen levels after liver transplant in patients with hepatic insufficiency. Materials and Methods: Medical records of all patients who underwent liver transplant at our hospital between January 2003 and June 2017 were retrospectively reviewed. Male patients who were > 40 years old with available pre-and posttransplant serum total prostate-specific antigen levels were included in the study. Results: Our study included 36 male patients with a mean age of 54.6 ± 5.3 years (range, 45-73 y) at the time of liver transplant. The mean pretransplant serum total prostate-specific antigen level was 0.75 ± 0.77 ng/mL, which was significantly lower than the mean posttransplant level of 1.29 ± 1.57 ng/mL (P <.05). The pretransplant serum total prostate-specific antigen level was measured a mean of 4.9 ± 5.4 months before liver transplant versus a mean 27.6 ± 16.3 months after transplant. Prostate-specific antigen velocity was 0.2 ng/mL/year. Biochemical tests of liver function, including the mean serum levels of bilirubin, international normalized ratio, and albumin, were normal after liver transplant at 1.37 ± 2.33 mg/dL, 1.22 ± 0.36, and 4.16 ± 0.69 g/dL, respectively. Conclusions: Serum prostate-specific antigen levels may decrease in patients with hepatic insufficiency/cirrhosis; therefore, a low serum prostate-specific antigen level may not be a reliable marker for excluding prostate cancer in such patients. Transplant surgeons and clinicians must be aware of this so that all male transplant candidates > 40 years old are evaluated via digital rectal examination, regardless of the serum prostate-specific antigen level.
