MRI对宫颈癌阴道受累及淋巴结转移的诊断价值

The Value of MRI in the Diagnosis of Vaginal Involvement and Lymph Node Metastasis of Cervical Cancer

目的探讨MRI检查对宫颈癌阴道受累及淋巴结转移的诊断价值。方法回顾性分析我院2016年1月至2017年1月收治的60例宫颈癌患者临床资料,宫颈癌均经手术病理证实,所有患者均行术前MRI检查和手术治疗,以术后病理结果为金标准,将MRI检查对阴道受累、淋巴结转移和国际妇产科联盟(FIGO)分期判断结果与其进行比较,分析MRI检查在阴道受累、淋巴结转移和FIGO分期方面的诊断价值。结果 (1)MRI诊断阴道受累的灵敏度、特异度和准确度依次为75.00%、92.31%、90.00%;误诊率和漏诊率依次为7.69%和25.00%。(2)MRI诊断淋巴节转移的灵敏度、特异度和准确度依次为76.92%、97.87%、93.33%;误诊率和漏诊率依次为2.13%和23.08%。(3)与病理结果相比,临床分期总体准确度为68.33%,MRI分期总体准确度为85.00%,临床分期总体准确度与MRI分期差异显著(P<0.05)。结论 MRI对宫颈癌阴道受累及淋巴结转移具有重要诊断价值,可以提高临床FIGO分期诊断准确率。

Objective To investigate the value of MRI examination in the diagnosis of vaginal involvement and lymph node metastasis of cervical cancer.Methods The clinical data of 60 patients with cervical cancer treated in our hospital from January 2016 to January 2017 were retrospectively analyzed,and cervical cancer was confirmed by surgery and pathology.All patients underwent preoperative MRI examination and surgical treatment.With postoperative pathological results as the golden standard,results of MRI in the diagnosis of vaginal involvement,lymph node metastasis and the International Federation of Gynecology and Obstetrics(FIGO)stage were compared.The value of MRI in the diagnosis of vaginal involvement,lymph node metastasis and FIGO stage was analyzed.Results①The sensitivity,specificity and accuracy of MRI in the diagnosis of vaginal involvement were 75.00%,92.31%and 90.00%,respectively.The misdiagnosis rate and missed diagnosis rate were 7.69%and 25.00%respectively.②The sensitivity,specificity and accuracy of MRI in the diagnosis of lymph node metastasis were 76.92%,97.87%and 93.33%,respectively.The misdiagnosis rate and missed diagnosis rate were 2.13%and 23.08%respectively.③Compared with the pathological results,the overall accuracy rates of clinical staging and MRI staging were 68.33%and 85.00%,respectively,with a significant difference(P<0.05).Conclusion MRI is of great value in the diagnosis of vaginal involvement and lymph node metastasis of cervical cancer,and it can improve the accuracy of clinical FIGO staging.
