Abstract:Objective: To evaluate predicted value of prostate specific antigen (PSA) and its related indexes in the diagnosis of prostate cancer (PCa). Methods: A total of 347 cases with tPSA range of 4-20 μg/L, were divided into two groups according to the tPSA levels. The various indexes, including fPSA, f/t PSA, PSAD, fPSAD, (f/t)/PSAD were analyzed. Results: In 222 patients with tPSA range of 4-10 μg/L, the positive rate of prostatic adenocarcinoma was 49.6%, and in the remaining 125 patients with tPSA range of 10-20 μg/L, that was 64.0% (P<0.05). There was no significant difference between PCa group and benign prostatic hyperplasia (BPH) group in age, BMI, tPSA, f/tPSA, and fPSAD. fPSA and (f/t)/PSAD were significantly lower in PCa group. ROC analysis indicated that PSAD and (f/t)/PSAD had the highest AUC value. For the cutoff values of 0.13 for PSAD, the sensitivity was 84.5% and specificity was 83.9%, and the AUC was 0.685. For the cutoff values of 1.26 for (f/t)/ PSAD, the sensitivity was 80.4% and specificity was 82.7%, and the (AUC) was 0.631. Conclusions: f/t PSA, PSAD and (f/t)/PSAD might be more effective in the基金项目:国家高技术研究发展计划(863计划) (2014AA020607)differential diagnosis between PCa and BPH with tPSA range of 4-20 μg/L.
