比较经阴式三维超声与磁共振成像在临床早期宫颈癌分期中的应用

摘要

Objective:To compare the diagnostic accuracy of transvaginal three-dimensional ultrasound(3D-TVUS)and magnetic resonance imaging(MRI)in the preoperative assessment of early-stage cervical cancer using pathologic findings as the reference standard.Methods:Prospective trial enrolling 30 consecutive women with early-stage cervical cancer(FIGO Ib1-Ⅱa2)scheduled for surgery.Before surgery cervical cancer was staged with clinical FIGO,3D-TVUS,MRI.The following parameters were assessed on US and MRI and compared to pathology:Tumor size,parametrial invasion and lymph node metastasis.Results:The agreement between 3D-TVUS and MRI was good staging cervical cancer.In the diagnosis of cervical cancer block diameter,parametrial invasion 3D-TVUS and MRI had a higher accuracy rate.3D-TVUS was better than MRI on diagnosising of lymph node metastasis.Conclusion:This application of 3D-TVUS and MRI in cervical cancer staging have a good accuracy.The study found that MRI is superior to 3D-TVUS in cervical cancer staging,but 3D-TVUS is practical,convenient and repeatable examination, and has practical value.Both methods help improve the preoperative staging of cervical cancer.%目的:探讨经阴式三维超声(3D-TVUS)与磁共振成像(MRI)在早期宫颈癌分期中的应用价值.方法:分析30例Ib1-Ⅱa2期临床早期宫颈癌手术患者,术前宫颈癌用临床FIGO、3D-TVUS、MRI进行分期,并与术后病理分期进行比较.比较用3D-TVUS和MRI对肿块大小、宫旁组织浸润和淋巴结转移的诊断.结果:3D-TVUS和MRI分期与术后病理分期一致性较好,在诊断宫颈癌肿块直径、宫旁组织浸润都有较高的准确率,诊断淋巴结转移3D-TVUS比MRI较优.结论:3D-TVUS与MRI对宫颈癌分期均有较好的准确率,MRI在宫颈癌分期中优于3D-TVUS技术,但3D-TVUS实用、方便、可重复检查,有实用价值,两种方法均有助于提高宫颈癌在术前的分期.
