子宫内膜癌肌层浸润深度的阴道超声诊断

Transvaginal Sonography in the Assessment of Myometrial Invasion Depth of Endometrial Cancer

目的 探讨阴道超声对子宫内膜癌的术前分期与病理诊断对照的准确性 .方法 术前应用经阴道超声(TVS)对 5 4例子宫内膜癌患者进行了检查、测量子宫肌层浸润深度 ,并与术后组织病理学结果对照分析 .结果 42例可见内膜回声 ,其平均厚度为 14 5± 5 .4mm(4 .8～ 2 5mm) .TVS准确判断出 85 2 %患者的肌层浸润深度 ,44例患者(81 5 % )的超声分期准确 .多普勒显示深肌层浸润者的阻力指数和搏动指数明显低于无肌层浸润者 .

Objective Transvaginal sonography preoperative staging of endometrial cancer.Methods Preoperative transvaginal sonography (TVS) was performed in 54 patients with endometrial cancer. The depth of myometrial invasion was measured and compared with postoperative histopathological findings.Results endometrial echoes were identified in 42 cases, and the average endometrial thickness was 14.5±5.4mm(range 4.8～25mm). Myometrial invasion was correctly predicted by TVS in 85.2% of the cases. Sonographic staging was accurate in 44 cases (81.5%). Dopple revealed the resistance index and pulsatility index values for deep invasion were significantly lower than that of no invasion.Conclusions The results indicated TVS may have an important role in preoperative staging of endometrial cancer, and in planning individual therapy.
