Effects of chronic bacterial prostatitis on prostate specific antigen levels total and free in patients with benign prostatic hyperplasia and prostate cancer.
BACKGROUND
Prostatic-specific antigen (PSA), a tumor marker helpful in the diagnosis and follow-up of prostate cancer, may rise due to causes such as prostatitis, chronic benign prostatic hyperplasia (BHP), etc. The aim of this study was to investigate the relationship between prostatitis and the level of total and free prostate-specific antigen in patients with no clinical evidence of prostate cancer.


METHODS
A comprehensive urological examination was performed on 156 patients aged 35-61 years old. All patients have symptoms of prostatitis. Prostate fluid culture was preformed. All patients underwent a course of antibacterial treatment after which the levels of total prostate specific antigen (TPSA) and free prostate specific antigen (FPSA) were evaluated.


RESULTS
An increase in TPSA (> 4 ng/ml) was observed in 14/24 (58.3%) patients with acute prostatitis and in 7/45 (15.5%) and 4/44 (9.1%) in patients with chronic bacterial prostatitis (CBP) and a bacterial prostatitis, respectively. Low blood concentration of TPSA and FPSA were observed after effective antibacterial and anti-inflammatory treatment therapy in most cases.


CONCLUSIONS
These data suggested that prostatitis must be considered when interpretation of TPSA and FPSA values as tumor marker.
