磁共振成像与阴道超声对子宫内膜癌术前分期的临床准确性对比

Comparison of the Clinical Accuracy of Preoperative Staging of Endometrial Carcinoma by Magnetic Resonance Imaging and Vaginal Ultrasound

目的分析磁共振成像与阴道超声对子宫内膜癌术前分期的临床准确性。方法选择59例子宫内膜癌患者,于手术前均行磁共振成像以及阴道超声检查。比较磁共振成像与阴道超声对子宫内膜癌术前分期的临床诊断准确率。结果以术后病理分期作为诊断的金标准,术前磁共振成像检查对子宫内膜癌Ⅰ期的临床诊断准确率为90. 91%(40/44),对Ⅱ期的临床诊断准确率为93. 33%(14/15);术前阴道超声检查对子宫内膜癌Ⅰ期的临床诊断准确率为88. 64%(39/44),对Ⅱ期的临床诊断准确率为86. 67%(13/15);磁共振成像与阴道超声检查对子宫内膜癌术前分期的临床诊断准确率相比无明显差异(P> 0. 05)。结论磁共振成像以及阴道超声对子宫内膜癌术前分期均具有较高的临床诊断准确性,可以为子宫内膜癌患者术前手术方案的选择和制定提供重要的参考依据。

Objective To analysis the clinical accuracy of preoperative staging of endometrial carcinoma by magnetic resonance imaging and vaginal ultrasound. Methods Selected 59 cases of patients with endometrial carcinoma. Magnetic resonance imaging and vaginal ultrasound examination were performed before the operation. To compare the clinical diagnostic accuracy of magnetic resonance imaging and vaginal ultrasound in the preoperative staging of endometrial carcinoma. Results Using postoperative pathological staging as the golden standard for diagnosis,preoperative magnetic resonance imaging has a diagnostic accuracy rate of 90. 91%( 40/44) for endometrial carcinoma in stage I,and the diagnostic accuracy rate for phase Ⅱ is 93. 33%( 14/15);The diagnostic accuracy of preoperative vaginal ultrasound for endometrial carcinoma I was 88. 64%( 39/44),and the accuracy rate for stage Ⅱ clinical diagnosis was 86. 67%( 13/15). There was no significant difference in the diagnostic accuracy of preoperative staging of endometrial carcinoma by magnetic resonance imaging and vaginal ultrasonography( P > 0. 05). Conclusion Magnetic resonance imaging and transvaginal ultrasound have high clinical diagnostic accuracy for preoperative staging of endometrial cancer,which can provide important reference for the selection and formulation of preoperative surgical plan for endometrial cancer patients.
