MRI对子宫内膜癌术前分期诊断价值

The Diagnostic Value of MRI for Preoperative Staging of Endometrial Cancer

目的:探讨MRI用于子宫内膜癌术前分期诊断中的方式与效果。方法:选取2011年1月-2013年6月笔者所在医院收治的50例经手术病理证实的子宫内膜癌患者,回顾性分析全组患者术前MRI检查图像,了解原发肿瘤信号特点、盆腔淋巴结转移情况、肌层浸润深度等征象,根据2009年国际妇产科联盟(FIGO)标准行术前MRI分期,对比术后病理结果。结果:本组患者MRI检查显示子宫体积增大40例,子宫大小正常6例,子宫萎缩4例;内膜厚度正常者5例,子宫内膜弥漫性不规则增厚27例,内膜局限不规则增厚18例。患者MRI术前检查与手术病理检查结果均为Ⅰa期33例、Ⅰb期9例、Ⅱ期5例、Ⅲ期2例、Ⅳ期1例,MRI术前检查与手术病理检查结果完全相符(准确度100%),浸润浅肌层(Ⅰa期)患者占绝大多数。结论:子宫内膜癌术前MRI检查可清晰观察到肿瘤灶范围、浸润深度、淋巴结转移情况,更准确地完成术前分期,便于科学制定手术计划和预后评估方案。

Objective：To evaluate the MRI for preoperative staging of endometrial cancer diagnosis manner and effect.Method：50 patients with pathologically confirmed endometrial cancer patients from January 2011 to June 2013 in our hospital were retrospectively analyzed,the MRI image was analyzed for all patients before surgery,to understand the signal characteristics of the primary tumor,pelvic lymph node metastasis,myometrial invasion and other signs. According to the 2009 International Union of Gynecology and Obstetrics（FIGO） staging before the standard preoperative MRI and postoperative pathological findings were contrasted.Result：MRI examination of the patient group showed uterine volume increased 40 cases,6 cases of normal uterine size,uterine atrophy 4 cases, endometrial thickness was normal in 5 cases,27 cases of endometrial diffuse irregular thickening,18 cases of endometrial limitations irregular thickening.Patients MRI preoperative and surgical pathology results wereⅠa period 33 cases,Ⅰb in 9 cases,Ⅱin 5 cases,Ⅲin 2 cases,Ⅳstage 1 case,MRI preoperative examination and surgical pathology results matched exactly（accurate degree 100%）,superficial myometrial invasion （Ⅰa period） were the vast majority of patients. Conclusion：The preoperative endometrial carcinoma can be clearly observed in MRI,such as the tumor foci range,depth of invasion,lymph node metastasis, the completion of a more accurate preoperative staging,it can scientifically formulate to facilitate surgical planning and prognosis assessment program.
