摘要
目的分析磁共振成像(MRI)对宫颈癌的诊断及其周围侵犯的判断价值。方法收集我院妇产科近4年(2014年3月-2018年3月)收治的71例宫颈癌患者的术前MRI影像资料,所有患者均经手术病理证实,以病理结果为参照,比较MRI检查对宫颈癌原发灶及癌变累及范围的显示效果,分析MRI检查对宫颈癌患者的诊断及其侵犯范围的评估价值。结果MRI无法显示宫颈癌Ia期,评估宫颈癌Ib期、II期、III期、IV期的准确性分别为95.65%(66/69)、86.96%(60/69)、94.20%(65/69)、100%(69/69),总准确度为85.92%(61/71),与病理结果无显著性差异(P>0.05);MRI对肿瘤累及阴道、宫体、宫旁组织评估的准确率分别为88.00%、72.73%、83.87%,灵敏度分别为88.89%、82.35%、91.67%、特异度分别为80.00%、40.00%、57.14%,阳性预测值分别为97.56%、82.35%、88.00%,阴性预测值分别为44.44%、40.00%、66.67%。结论MRI检查对宫颈癌原发灶及其侵犯范围判断较准确,具有较高的临床价值,可将其作为术前诊断及术后降期评估的有效依据。
Objective To analyze the value of magnetic resonance imaging(MRI)in the diagnosis of cervical cancer and the judgment of surrounding invasion.Methods The preoperative MRI imaging data of 71 patients with cervical cancer admitted to our department of obstetrics and gynecology of our hospital in recent four years(from March2014 to March 2018)were collected.All patients were confirmed by surgical pathology.The pathological results were taken as reference to compare the display effects of MRI towards the primary focus of cervical cancer and the extent of cancer involvement,and to analyze the estimated value of MRI in the diagnosis and invasion scope of patients with cervical cancer.Results MRI could not show stage Ia of cervical cancer,and the accuracies of MRI in evaluating stageⅠb,stageⅡ,stageⅢand stageⅣof cervical cancer were95.65%(66/69),86.96%(60/69),94.20%(65/69)and 100%(69/69)respectively,and the total accuracy was 85.92%(61/71),and there was no significant difference compared with the pathological results(P >0.05).The accuracies of MRI in the evaluation of tumor involving vagina,corpus and parametrium were 88.00%,72.73%and 83.87%respectively,and the sensitivities were 88.89%,82.35%and 91.67%,and the specificities were 80.00%,40.00%and 57.14%respectively,and the positive predictive values were 97.56%,82.35%and 88.00%respectively,and the negative predictive values were 44.44%,40.00%and66.67%respectively.Conclusion MRI examination has a relatively accurate judgment on the primary lesions and invasion scope of cervical cancer,and has high clinical value.And it can be used as an effective basis for preoperative diagnosis and postoperative assessment in clinic.
