Abstract Purpose This study aimed to identify parameters with a higher diagnostic value for early screening of prostate cancer (PCa) at different ages. Materials and Methods A total of 294 patients were included and divided into two groups according to the age of patients (≤66 and >66 years). Receiver operating characteristic (ROC) curves of total prostate‐specific antigen (TPSA), free PSA (FPSA), (F/T)PSA, PSA density (PSAD), PSA–AV score, the ratio of patients' age to prostate volume (AVR) and (F/T)/PSAD were constructed. The area under the ROC curve (AUC) was calculated, and differences in the AUC values among the above‐mentioned parameters were compared. Results There were 121 patients in the ≤66 years age group (benign prostatic hyperplasia BPH, 103 patients; PCa 18 patients) and 173 patients in the >66 years age group (BPH, 100 patients; PCa, 73 patients). In the ≤66 years age group, the AUC value of AVR for PCa diagnosis was the highest; however, there was no statistically significant difference compared with the AUC values of PSAD and (F/T)/PSAD; compared with TPSA, FPSA, (F/T)PSA and PSA‐AV, the differences were statistically significant. In the >66 years age group, the AUC values of PSAD and PSA–AV for PCa diagnosis were higher than those of TPSA, FPSA, (F/T)PSA and (F/T)/PSAD, and the difference was statistically significant; however, the difference was not statistically significant when compared with the AUC value of AVR. Conclusion In different age groups, screening indices for PCa diagnosis should be selected according to the age of patients.
