目的比较MRI和经阴道彩色多普勒超声(TVUS)在早期宫颈癌术前评估中的应用价值。方法回顾性分析35例经手术病理证实的早期宫颈癌患者(临床分期为Ⅰb和Ⅱa期)的MRI及TVUS资料,统计分析单独应用MRI、TVUS及两者联合应用在早期宫颈癌术前评估的准确率。结果肿瘤直径、宫颈间质浸润、宫旁受累3项指标准确率两者差异无统计学意义(P>0.05),在阴道受侵准确率方面,MRI明显优于TVUS,两者差异具有统计学意义(P<0.05);淋巴结受累方面,准确率差异无统计学意义(P>0.05),TVUS灵敏度明显高于MRI,特异度低于MRI。在5项指标中,联合应用准确率明显优于单一检查,差异具有统计学意义(P<0.05)。结论 MRI和TVUS在早期宫颈癌诊断中各有优势,联合应用显著提高术前评估的准确率。
Objective To compare the value of MRI and transvaginal color Doppler ultrasound (TVUS) in the preoperative evaluation of early cervical cancer. Methods We retrospectively analyzed MRI and TVUS data of 35 patients with early stage cervical carcinoma confirmed by surgery and pathology (clinical stage Ⅰb and Ⅱa). Statistical analysis of MRI, TVUS alone and their combination in early cervical cancer preoperative evaluation Accuracy. Results There was no significant difference in tumor diameter, cervical interstitial infiltration and uterine involvement among the three indicators (P> 0.05). MRI was superior to TVUS in the accuracy of vaginal invasion, and the difference was statistically significant (P <0.05). There was no significant difference in the accuracy of lymph node involvement (P> 0.05). The sensitivity of TVUS was significantly higher than that of MRI and the specificity was lower than that of MRI. Among the 5 indicators, the accuracy of the combined application was significantly better than that of the single test, the difference was statistically significant (P <0.05). Conclusion MRI and TVUS have their own advantages in the diagnosis of early cervical cancer. The combination of MRI and TVUS can significantly improve the accuracy of preoperative evaluation.
