摘要
目的探讨MRI诊断宫颈癌的临床价值。方法回顾性分析2013年05月至2016年04月于我院妇产科行盆腔MRI检查的224例疑似宫颈癌初诊患者的临床资料,通过分析其MRI图像,观察比较MRI诊断与术后病理学诊断宫颈癌及宫旁浸润、阴道受侵、淋巴结转移的灵敏度、特异度、阳性预测值、阴性预测值、准确率,同时比较MRI分期与手术-病理分期及术前临床分期准确性。结果以术后病理学检查为金标准,MRI诊断宫颈癌灵敏度为97.06%,特异度为80.0%,MRI诊断宫旁浸润的灵敏度为80.0%,特异度为96.20%,MRI诊断阴道受侵的灵敏度为87.72%,特异度为93.88%,MRI诊断淋巴结转移的灵敏度为89.04%,特异度为96.18%,MRI分期和手术病理分期与术前临床分期比较,差异具有统计学意义(χ2=14.394和14.595,P<0.05),而MRI分期与手术病理分期比较无显著性差异(χ2=0.198,P>0.05)。结论 MRI对于宫颈癌诊断准确率高,在宫旁浸润、阴道受侵及淋巴结转移具有较高灵敏度和特异性,与术后病理相比,MRI对宫颈癌分期准确度较高,可以为宫颈癌诊断和治疗提供理论依据。
Objective To explore the clinical value of MRI in the diagnosis of cervical cancer. Methods The clinical data of 224 patients with suspected cervical cancer treated with pelvic MRI examination in the obstetrics and gynecology department of our hospital from May 2013 to April 2016 were analyzed retrospectively. Through the analysis of the MRI image, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate of cervical cancer and uterine infiltration, vaginal invasion and lymph node metastasis were observed and compared by MRI diagnosis and postoperative pathological diagnosis. The accuracy of MRI staging and surgical pathological staging and preoperative clinical staging were also compared. Results Postoperative pathological examination was taken as the gold standard, and the sensitivity and specificity were respectively 97.06% and 80% in the cervical cancer, and 80% and 96.20% in the uterine infiltration and 87.72% and 93.88% in the vaginal invasion and 89.04% and 96.18% in the lymph node metastasis by MRI diagnosis. The differences were statistically significant in the comparison of MRI staging and surgical pathological staging and preoperative clinical staging（χ~2=14.394 and 14.595, P〈0.05）, but the comparison of MRI staging and surgical pathological staging was not statistically significant（χ~2=0.198, P〈0.05）. Conclusion MRI has high accuracy in the cervical cancer diagnosis and high sensitivity and specificity in the determination of uterine infiltration, vaginal invasion and lymph node metastasis. Compared with postoperative pathology, MRI has higher accuracy in the cervical cancer staging, and can provide theoretical basis for cervical cancer diagnosis and treatment.
