磁共振成像在FIGO I II期子宫内膜癌术前分期中的应用

Value of magnetic resonance imaging in preoperative staging of FIGO Stage I and II endometrial carcinoma

目的探讨MRI在子宫内膜癌术前分期中的价值。方法经分段诊刮及手术病理证实的88例子宫内膜癌患者术前行MRI检查,判断子宫肌层浸润程度和宫颈侵犯情况并进行术前分期,将术前分期与手术病理分期结果进行比较。结果 88例子宫内膜癌病理分期Ⅰa期57例,Ⅰb期22例,Ⅱ期9例。按照FIGO 2009分期标准,术前MRI分期Ⅰa期、Ⅰb期、Ⅱ期准确率分别为96.6%、94.3%和97.7%。结论应用MRI评价子宫内膜癌肌层浸润程度和宫颈侵犯情况较准确,能提高术前分期的准确性。

Objective To discuss the value of magnetic resonance imaging（MRI） in preoperative staging of endometrial carcinoma. Methods MR1 examinations were performed before surgery in 88 patients with endometrial carcinoma of FIGO stage I to II confirmed pathologically. The appearance of junctional zone, the depth of myometrial invasion and cervical invasion were observed, and preoperative staging was performed. The results of preoperative staging were compared with postoperative pathological findings. Results Among 88 cases patho- logically - proven endometrial carcinoma, there were 57 cases of stage Ia, 22 cases of Ib and 9 cases of II. The accuracy of MRI in the staging of endometrial carcinoma using the new FIGO staging system was 96.6% , 94.3% and 97.7% for stage Ia, Ib and II respectively. Conclusion MRI is accurate and reliable in evaluating myometrial invasion and cervical invasion of endometrial carcinoma, which may be per- formed as a routine preoperative examination.
