为检测超声检查描述子宫内膜癌病例子宫肌层浸润深度及子宫颈累及程度的精确性,术前常规使用腹部和阴道探头对69例子宫内膜癌的患者行盆腔超声检查,并在超声检查后4天之内进行手术。采用高分辨率的阴道探头评估子宫内14肿瘤浸润情况,由专人操作。子宫肌层浸润深度的测量是从子宫内膜与子宫肌层间的界面到肿瘤侵蚀子宫肌层深度的边缘,浸润深度分为未浸润、浸润<50％及>50％。子宫颈的累及是根据在子宫颈口肿瘤的不规则回声来确定。超声检查所见与病理学检查结果互相对照。 结果表明,69例中63例超声检查未见子宫颈浸润,而病理检查仅60例阴性,即超声俭查有3例假阴性,无假阳性,有极显著相关性(P<0.001)。其中5例子宫颈管内膜受累(Ⅱa期),4例为Ⅱb期。3例假阴性病例均为Ⅱa期,其中2例在显微镜下确诊,第3例经组织学证实已扩散到子宫颈内口,因而确认为子宫颈受累。 子宫肌层浸润<50％者28例,>50％31例,无浸 To determine the accuracy of ultrasonography in describing the depth of myometrial invasion and the degree of cervix involvement in endometrial cancer, preoperative abdominal and vaginal probes were used to perform pelvic ultrasonography in 69 patients with endometrial cancer and were examined by ultrasound. Surgery is performed within 4 days. A high-resolution vaginal probe was used to assess intrauterine 14 tumor infiltration and was performed by a specialist. The myometrial invasive depth is measured from the interface between the endometrium and myometrium to the edge of the depth at which the tumor erodes the myometrium. The depth of invasion is classified as noninfiltrated, infiltrated <50% and> 50%. Involvement of the cervix is ​​determined based on the irregular echo of the tumor at the cervix. Ultrasonography contrasted with pathological findings. The results showed that 63 cases of 63 cases of ultrasound examination did not see cervical infiltration, while only 60 cases of pathological examination were negative, that is, there were 3 cases of false-negative ultrasound false negative, no false positive, there is a very significant correlation (P <0.001). Of these, 5 were involved in endometrial involvement (stage IIa) and 4 were stage IIb. All three false-negative cases were in stage IIa, of which 2 cases were diagnosed under a microscope. The third case was confirmed by histology and spread to the inner os of the cervix, thus confirming that the cervix was involved. Infiltration of myometrium <50% in 28 cases,> 50% in 31 cases, no immersion
