OBJECTIVE. The authors investigated the value of comprehensive assessment of clinical and laboratory factors including prostate specific antigen (PSA) fractions and prostate health index (PHI) in diagnostics of prostate cancer. MATERIALS AND METHODS. The study numbered 148 patients who were examined for suspected prostate cancer. Clinicians made the measurement of total PSA and fractions, PHI, multifocal transrectal biopsy of prostate. The statistical data were analyzed. RESULTS. The formulas obtained used the discriminant analysis of all clinical and laboratory factors (PSA fractions and PHI). These formulas showed the high possibility (77-80 %) to predict the presence of prostate cancer with sensitivity 70-78 % and specificity 77-83 %. Percentage of [-2]proPSA depended on PHI value and had the significant influence on the possibility of prostate cancer detection.
