摘要
目的 探讨基于多参数磁共振(mp-MRI)的前列腺影像报告和数据系统(PI-RADS)评分在前列腺癌术前分期的诊断价值.方法 选取医院2021年3月-2022年4月收治的102例疑似前列腺癌患者,全部患者均行mp-MRI检查,对mp-MRI图像进行PI-RADS评分,并行手术病理或穿刺活检检查,将手术病理或穿刺活检检查结果作为"金标准",分析mp-MRI的PI-RADS评分对前列腺癌及术前分期的诊断效能.结果 102例疑似前列腺癌患者经手术病理或穿刺活检确诊73例,占71.57%,其中A期12例,B期24例,C期29例,D期8例;依据手术病理或穿刺活检检查"金标准",mp-MRI的PI-RADS评分对前列腺癌的诊断灵敏度为95.89%(70/73)、特异度为96.55%(28/29)、准确度为96.08%(98/102),且mp-MRI的PI-RADS评分对前列腺癌临床分期的诊断符合率为93.15%(68/73),其与手术病理或穿刺活检检查结果一致性极好(Kappa值=0.901).结论 基于mp-MRI的PI-RADS评分对前列腺癌术前诊断与分期具有较高诊断价值,值得临床推广应用.
Abstract
Objective To investigate the diagnostic value of multi-parameter magnetic resonance(mp-MRI)based prostate imag-ing reporting and data system(PI-RADS)score in the preoperative stage of prostate cancer.Methods The 102 patients with suspected prostate cancer admitted to the hospital from March 2021 to April 2022 underwent mp-MRI,PI-RADS score was performed on mp-MRI images,and surgical pathology or needle biopsy was performed in parallel.The results of surgical pathology or needle biopsy were regarded as the"gold standard".To analyse the diagnostic efficacy of PI-RADS score of mp-MRI on prostate cancer and preoperative stage.Results 73 of 102 patients with suspected prostate cancer were confirmed by surgical pathology or needle biopsy,accounting for 71.57%,among these,12 cases were in stage A,of the 24 patients in stage B,of the 29 patients in stage C,8 cases in stage D.Accord-ing to the"gold standard"of surgical pathology or needle biopsy examination,the PI-RADS score of mp-MRI had a diagnostic sensitiv-ity of 95.89%(70/73),specificity of 96.55%(28/29)and accuracy of 96.08%(98/102).Moreover,the rate of PI-RADS score for clinical stage of prostate cancer was 93.15%(68/73),It showed excellent agreement with surgical pathology or needle biopsy results(Kappa value=0.901).Conclusion PI-RADS score based on mp-MRI has high diagnostic value for preoperative diagnosis and staging of prostate cancer and is worthy of clinical application.
