Abstract
The study aims to measure the effectiveness of the prostatic acid phosphatase in the blood serum of patients with prostate cancer as a predictor for diagnosing this pathology, measuring the concentration of the prostatic specific antigen and measuring oxidative stress by measuring the lipid peroxidation of malondialdehyde and clutathione. Results indicated that there was a statistically significant increase in the effectiveness of the prostatic acid phosphatese in the blood serum of the persons infected with prostate cancer compared to the healthy persons.
