Abstract

The Prostate Cancer Prevention Trial risk calculator (PCPT-RC) is an online tool for assessing the risk of prostate cancer (PCa) based on age, race, serum PSA, biopsy history, family history, and other factors. This study aimed to investigate the value, sensitivity and specificity of the PCPT-RC 2.0 in assessing the risk of PCa in the Chinese high-risk population. This study included 622 patients with the high risk of PCa characterized by high serum PSA (PSA >3 μg/L) or abnormality in digital rectal examination or imaging of the prostate. According to the results of prostate biopsy, we divided the patients into a PCa and a non-PCa group and used the PCPT-RC 2.0 for evaluation of all the cases followed by statistical analysis. PCa was detected in 264 (42.4%) of the 622 patients, including 126 cases of high-grade malignancy. Compared with the non-PCa group, the PCa patients showed a significantly older age ([68.40 ± 7.30] vs [72.80 ± 7.20] yr, P <0.001), higher serum PSA level ([11.20 ± 7.76] vs [15.06 ± 10.65], P <0.001), and higher PCPT risk score ([37.0 ± 10.8]% vs [44.4 ± 12.6]%, P <0.001). The PCPT risk score exhibited a greater area under the ROC curve than the level of serum PSA in evaluating the risk of PCa (0.67 vs 0.61,...Continue Reading
