The predictive value of PI-RADS v2 based on multi-parameter magnetic resonance imaging combined with f/t PSA and PSAD in prostate cancer

Objective To investigate the predictive value of PI-RADS V2 based on multi-parameter magnetic resonance imaging combined with f/t PSA and PSAD in prostate cancer. Methods All the clinical data of 289 patients with suspected prostate cancer were analyzed in the hospital of Yangchun city from January 2015 to December 2020, retrospectively. 123 patients with prostate cancer （PCa） were selected as PCa group, and 166 cases without PCa were selected as Non-PCa group. The receiver operator characteristic curve were performed to verify the diagnostic value of PI-RADS v2, the f/t PSA and PSAD, and the area under curve （AUC） were calculated. The sensitivity and specificity of the prostate cancer were analyzed by three diagnostic indicators and joint indicators. Results The consistency test between two groups showed that Kappa coefficient was 0.798, which indicated that the scoring results of the two physicians were highly consistent. The AUC of the diagnostic indexes of PI-RADS v2, f/t PSA, PSAD and the combined indexes were 0.633, 0.796, 0.785 and 0.908, respectively.The difference was statistically significant. Conclusion PI-RADS v2 combined with f/t PSA and PSAD can be used as Objective indicators for the early diagnosis of prostate cancer, and it is worthy of promotion.
