经阴道超声造影检查对子宫内膜癌肌层浸润深度的诊断价值

Clinical value of contrast-enhanced TVS in the assessment of invasion depth of endometrial cancer

目的探讨经阴道超声造影检查在定位子宫内膜癌肌层浸润深度方面的诊断价值。方法对经手术病理证实为子宫内膜癌28例患者进行超声造影检查，判断肌层浸润深度，并与术后病理结果进行比较。结果28例子宫内膜癌患者术前经阴道超声造影检查判断宫体肌壁浸润总符合率为78．6％（22／28）；表浅浸润（无肌层浸润＋浅肌层浸润）与深肌层浸润鉴别诊断符合率达96．0％；无肌层浸润敏感度71．4％、特异度85．7％、符合率为62．5％；浅肌层浸润敏感度性73．7％、特异度77．8％、符合率为87．5％；深肌层浸润的敏感度100．0％、特异度96．0％、符合率为75．0％。经阴道超声造影在子宫内膜癌不同浸润深度的诊断符合率差异元统计学意义。结论经阴道超声超声造影检查能较准确的判断子宫内膜癌肌层浸润深度。

Objective To discuss the diagnostic value of contrast-enhanced transvaginal sonography TVS in the diagnosis of myometrial invasion grade of endometrial cancer. Methods Total twenty-eight cases were studied by contrast-enhanced ＂INS, which were proved pathologically endometrial cancer in our hospital. The diagnosis of myometrial invasion grade of endometrial cancer by contrast-enhanced TVS were compared with pathologic results hased on FIGO. Results The total coincidence of contrast-enhanced transvaginal sonography in detecting the depth of myometrial invasion was 78.6%. In the evaluation of no myometrial invasion,it showed the sensitivity of 71.4% ,specificity of 85.7% and coincidence of 62.5%. In evaluation of superficial myometrial invasion, the sensitivity, specificity and coincidence was 73.7% ,77.8%, 87.5%, respectively. The sensitivity in detecting deep invasion was 100.0%, the specificity was 96.0% ,while coincidence was 75.0%. There was no significant difference among the coincidence of various depth of myometrial invasion by contrast-enhanced TVS. Conclusion Contrast-enhanced TVS was valuable in the diagnosis of myometrial invasion grade of endometrial cancer.
