Objective:To evaluate the diagnostic value of PSA and the f/t PSA ratio in prostate cancer screening in Chinese people.Methods:Original articles on the application of PSA and f/t PSA ratio in prostate cancer screening among Chinese population were retrieved from Pubmed, Embase, Cochrane, China National Knowledge Infrastructure (CNKI), Wanfang data and VIP databases from the establishment of the database to June 2023. The literature quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2(QUADAS-2) tool. A meta-analysis was performed with Stata 15.1 software.Results:A total of 26 articles were included, encompassing 18 407 individuals, of whom 4 095 were diagnosed with prostate cancer based on biopsy and postoperative pathological examination, while the rest were patients with other prostate diseases or healthy individuals. 24 used a PSA threshold of>4.0 ng/ml as the cutoff for prostate cancer screening, the pooled sensitivity was 0.88(95% CI: 0.84-0.91), the specificity was 0.42(95% CI: 0.34-0.50), and the area under the summary receiver operating characteristic (SROC) curve (AUC) was 0.7(95% CI: 0.73-0.81). Four articles considered a PSA threshold of>10.0 ng/ml for prostate cancer screening (three of which used the above two cutoff values), the pooled sensitivity was 0.83(95% CI: 0.74-0.89), the specificity was 0.67(95% CI: 0.45-0.84), and the AUC of the SROC was 0.79(95% CI: 0.75-0.83). Eleven articles used the f/t PSA ratio as a screening tool for prostate cancer. When the f/t PSA ratio was<0.16, the pooled sensitivity was 0.82(95% CI: 0.76-0.87), the specificity was 0.76(95% CI: 0.67-0.83), and the AUC of the SROC was 0.86(95% CI: 0.83-0.89). Conclusion:In the screening for prostate cancer in China, PSA has a relatively high sensitivity, and the f/t PSA ratio has a better specificity. Combined application of the two indices is recommended.
