摘　　要：目的探讨基于直肠超声的前列腺穿刺活检在前列腺癌患者中的诊断价值。方法随机选取2020年6月—2023年6月威海市立医院超声医学科收治的100例疑似前列腺癌患者为研究对象,所有患者均接受手术病理检查(金标准),术前行基于直肠超声的前列腺穿刺活检,分析其临床诊断效果及安全性;绘制受试者操作特征(receiver operating characteristic,ROC)曲线,分析经直肠超声引导下前列腺穿刺活检临床诊断效能。结果100例疑似前列腺癌患者经手术病理检查确诊53例,经直肠超声引导下前列腺穿刺活检确诊49例。kappa值为0.751。ROC曲线结果表明,基于直肠超声的前列腺穿刺活检在前列腺癌患者中诊断曲线下面积值为0.878,诊断灵敏度为88.68%,诊断特异度为95.74%。结论经直肠超声引导下前列腺穿刺活检用于前列腺癌患者中能获得较高的诊断符合率,帮助早期确诊,降低病理检查次数,可指导临床诊疗。Objective To explore the diagnostic value of prostate biopsy based on rectal ultrasound in patients with prostate cancer.Methods A total of 100 patients with suspected prostate cancer admitted to the Department of Ultrasound Medicine,Weihai Municipal Hospital from June 2020 to June 2023 were randomly selected as the study objects.All patients underment surgical pathology examination(gold standard).Preoperative prostate biopsy based on rectal ultrasound was performed to analyze its clinical diagnostic effect and safety.The receiver operating characteristic(ROC)curve was drawn to analyze the clinical diagnostic performance of prostate biopsy guided by transrectal ultrasound.Results 53 cases were confirmed by surgical pathology examination in 100 patients with suspected prostate cancer,and 49 cases were confirmed by transrectal ultrasoundguided prostate biopsy.The kappa value was 0.751.The ROC curve results showed that the diagnostic area under curve value of prostate biopsy based on rectal ultrasound in patients with prostate cancer was 0.878,the diagnostic sensitivity was 88.68%,and the diagnostic specificity was 95.74%.Conclusion Transrectal ultrasound-guided prostate biopsy can achieve a high diagnostic accuracy rate in patients with prostate cancer,help patients to be diagnosed early,reduce the number of pathological examinations,and can guide clinical diagnosis and treatment.
