目的探讨多层螺旋CT对宫颈癌淋巴结转移的诊断价值。方法选取2014年1月至2015年8月我院收治的经病理证实的宫颈癌淋巴结转移患者81例为研究对象,术前1周行多层螺旋CT检查,与术后病理检查结果进行比较,分析CT检查的诊断效能。结果多层螺旋CT检查的诊断敏感度、特异度、准确率、阳性预测值和阴性预测值分别为83.8%(31/37)、90.9%(40/44)、87.7%(71/81)、88.6%(31/35)、87.0%(40/46);髂总动脉的诊断敏感度、特异度分别为86.5%、67.6%,髂内动脉的诊断敏感度、特异度分别为83.8%、73.0%,骼外动脉的诊断敏感度、特异度分别为89.2%、73.0%,腹主动脉的诊断敏感度、特异度分别为86.5%、70.3%。结论多层螺旋CT检查在宫颈癌淋巴结转移中的诊断价值高,但临床上需综合分析淋巴结的大小、数目及密度,有助于疾病的准确诊断和治疗。
Objective To investigate the diagnostic value of multislice spiral CT in cervical lymph node metastasis. Methods From January 2014 to August 2015, 81 patients with pathologically confirmed cervical lymph node metastasis admitted to our hospital from January 2014 to August 2015 were enrolled in this study. Multi-slice spiral CT was performed one week before surgery and compared with postoperative pathological findings. Analyze the diagnostic efficacy of CT examination. Results The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of multi - slice spiral CT were 83.8% (31/37), 90.9% (40/44), 87.7% (71/81), respectively The diagnostic sensitivity and specificity of common iliac artery were 86.5% and 67.6% respectively. The diagnostic sensitivity and specificity of internal iliac artery were 83.8% and 73.0%, respectively %. The diagnostic sensitivities and specificities of extra-articular arteries were 89.2% and 73.0% respectively. The diagnostic sensitivity and specificity of abdominal aorta were 86.5% and 70.3% respectively. Conclusion MSCT has high diagnostic value in lymph node metastasis of cervical cancer. However, it is necessary to analyze the size, number and density of lymph nodes comprehensively in clinical diagnosis, which is helpful for the accurate diagnosis and treatment of cervical cancer.
