宫颈癌的MRI分期与临床及病理分期对照研究

Comparative study of magnetic resonance imaging staging with clinical and patholgic staging of cervical carcinoma

目的:探讨宫颈癌MRI及临床分期价值,并评价MRI对于宫颈癌术前分期的优越性。方法:回顾性分析我院61例具有完整MRI检查及临床资料的宫颈癌患者,参照FIGO分期标准,利用双盲法于术前分别做出宫颈癌的临床及MRI分期,然后进行MRI、临床及术后病理分期的比较。结果:MRI对宫颈癌分期诊断总的准确率为85.2%(52/61),特异性为89.7%(52/58),敏感度达95.1%,临床对宫颈癌总的准确率为63.9%(39/61)。结论:MRI对于宫颈癌分期明显优于临床分期,特别对于提示宫颈癌侵犯宫体、宫旁结构及盆腔内淋巴结的转移等方面也更为客观性,应该成为术前常规检查。

Objective:To investigate the use of MRI and its clinical value in staging cervical carcinoma,and to evaluate the advantages of using MRI in the preoperative staging of cervical carcinoma.Methods:Based on the retrospective analysis of the 61 patients with cervical carcinoma who underwent the complete MRI examination as well as the clinical data,along with referring to the FIGO staging sandards,this thesis,by using the double-blind technique,achieved the clinical analysis and the MRI staging before the operation,and made a comparison between MRI staging clinical staging,and pathologic staging.Results:The accuracy,specificty and sensitivty achieved by MRI in staging cervical carcinoma were 85.2%,89.7% and 95.1%,respectively.The accuracy of the clinical staging of cervical carcinoma was 63.9%.Conclusion:According to this thesis,the accuracy of MRI for cervical carcinoma excels the one for clinical staging,especially in the aspect of detecting the uterine corpus,parametrial ivasion and pelviclymph node metastasis.It is suggested that MRI should be regarded as aconventional examination for patients with cervical carcinoma.
