摘要
目的评估磁共振成像(MRI)对子宫内膜癌肌层侵犯深度判断的价值。方法回顾性分析57例经手术病理证实的子宫内膜癌患者,术前行MRI平扫及增强检查。MRI对57例患者进行临床分期,并与术后病理结果进行对照。结果 MRI观察子宫内膜癌浸润深度局限于内膜11例,浸润浅肌层21例,浸润深肌层13例,浸透浆膜12例。对照病理结果,对肿瘤局限于内膜的敏感性、特异性和准确性分别为81.8%、95.7%、92.9%,浸润浅肌层的敏感性、特异性和准确性分别为85.7%、91.7%、89.4%,浸犯深肌层的敏感性、特异性和准确性分别为84.6%、95.5%、92.9%,浸透浆膜的敏感性、特异性和准确性分别为91.7%、97.8%、96.4%。结论 MRI可以对子宫内膜癌进行准确分期,尤其对准确判断肌层有无浸润有明显的优势。
Objective To evaluate the value of MR imaging in the assessment of invasion depth by endometrial carcinoma.Methods The data of 57 patients with endometrial carcinoma proved by postoperative pathology were reropectively revewed.Preoperatively,all patients underwent conventional and contrast-enanced MR scan.The staging results of MRI were compared with pathologic results and analysed with statistic methods.Results Based on MRI image,the tumor was confined to the endometrium in 11 patients,causing superficial myometrial invasion 21,deep-myometrial invasion 13 and having penetrated the serosa 12.Compared with pathologic results,the incidence of sensitivity,specficity and accuracy of MRI assessment for tumor confined to endometrium was 81.8%,95.7% and 92.9%,respectively;to superficial myometrial invasion：85.7%,91.7% and 89.4%,respectively;to deep-myometrial invasion： 84.6%,95.5% and 92.9%,respectively;to tumor having penetrated the serosa： 91.7%,97.8% and 96.4%.Conclusion The endometrial carcinoma can be staged further by MRI,MRI has significant advantage in estimating the invasion of myometrium.
