Abstract

OBJECTIVE

To evaluate MR accuracy for staging endometrial carcinoma with different FIGO staging systems.

METHODS

Between August 2006 and July 2010, 95 women underwent surgery for endometrial carcinoma.In each patient, endometrial carcinoma was staged with magnetic resonance (MR) findings based on the old FIGO staging system and then repeated according to the new FIGO staging system for comparisons.Histopathologic findings were used as a golden standard to compare the sensitivity, specificity, accuracy, positive predictive value and negative predictive value.

RESULTS

The accuracy of MRI in the staging of endometrial carcinoma stageI, II and III with the old FIGO staging system were 83.2%, 86.3% and 92.6% versus 88.4%, 96.8% and 91.6% respectively with the new FIGO staging criteria.According the old FIGO staging system, the sensitivity of stage IA, IB and IC were 51.8%, 76.5% and 50.0% and the specificity 85.3% , 55.7% and 95.4% respectively; the sensitivity of stage IIA and IIB were merely 12.5% and 20.0% and the specificity 97.7% and 100.0%.With the new FIGO staging criteria, the above indices were 97.1%, 55.6%, 57.7%, 95.3%, 40.0% and 100.0% respectively.

CONCLUSION

With new FIGO staging system versus the old one, the accuracy of MR imaging in the preoperative staging of endometrial carcinoma increases.

摘要

目的

评估磁共振成像（MR）在不同国际妇产科联盟（FIGO）分期系统中对子宫内膜癌进行分期的准确性。

方法

2006年8月至2010年7月期间，95例女性接受了子宫内膜癌手术。对每例患者，根据旧的FIGO分期系统，依据磁共振成像（MR）结果对子宫内膜癌进行分期，然后再根据新的FIGO分期系统重复分期以进行比较。组织病理学结果用作金标准，以比较敏感度、特异度、准确度、阳性预测值和阴性预测值。

结果

旧的FIGO分期系统中，MR对子宫内膜癌Ⅰ期、Ⅱ期和Ⅲ期进行分期的准确度分别为83.2%、86.3%和92.6%，而新的FIGO分期标准下分别为88.4%、96.8%和91.6%。根据旧的FIGO分期系统，ⅠA期、ⅠB期和ⅠC期的敏感度分别为51.8%、76.5%和50.0%，特异度分别为85.3%、55.7%和95.4%；ⅡA期和ⅡB期的敏感度仅为12.5%和20.0%，特异度分别为97.7%和100.0%。采用新的FIGO分期标准时，上述指标分别为97.1%、55.6%、57.7%、95.3%、40.0%和100.0%。
