摘要
目的:分析PI-RADS v2.1评分对前列腺癌(PCa)的诊断价值。方法:回顾性研究2020年3月—2023年5月安徽医科大学附属阜阳医院收治的疑似PCa患者97例,根据病理结果分为PCa组(n=51)和非PCa组(n=46),术前患者均行前列腺多参数MRI检查并用PI-RADS v2.1版评分。绘制受试者工作特征(ROC)曲线,分析PI-RADS v2.1评分对诊断PCa的价值。探讨PCa患者PI-RADS v2.1评分与PCa患者Gleason评分之间的关系。结果:PI-RADS v2.1评分检出PCa的曲线下面积为0.930,95%CI:0.875~0.984;截断值选为4时,对应的约登指数(0.746)和准确率(87.63%)最高,灵敏度为94.12%,特异度为80.43%。PI-RADS v2.1评分越高对应的PCa阳性率也越高,Gleason评分高分值占比也越高。结论:多参数MRI PI-RADS v2.1评分对诊断PCa有很高的价值,PI-RADS v2.1评分越高提示Gleason高分PCa的风险越大。
Objective To explore the diagnostic value of PI-RADS v2.1 score for prostate cancer(PCa).Methods A retrospective study was conducted on 97 suspected PCa patients admitted to Fuyang Hospital of Anhui Medical University from March 2020 to May 2023.According to pathological results,they were divided into PCa group(n=51)and non PCa group(n=46),preoperative patients underwent prostate multi parameter MRI and were scored using PI-RADS v2.1 version.Receiver operating characteristic(ROC)curves were plotted to analyze the value of PI-RADS v2.1 scoring in diagnosing PCa.The relationship between the PI-RADS v2.1 scores of PCa patients and their Gleason scores was explored.Results The area under the curve for detecting PCa in PI-RADS v2.1 score is 0.930,95%CI:0.875~0.984;When the truncation value is selected as 4,the highest corresponding Jordan index(0.746)and accuracy rate(87.63%),sensitivity is 94.12%,specificity is 80.43%.The higher the PI-RADS v2.1 score,the higher the corresponding positive rate of PCa,the higher the proportion of high Gleason scores.Conclusion Multi parameter MRI PI-RADS v2.1 score has high value in diagnosing PCa,the higher the PI-RADS v2.1 score,the greater the risk of diagnosing Gleason's high score PCa.
