多层螺旋CT检查诊断宫颈癌淋巴结转移的临床研究

目的:探讨多层螺旋CT检查诊断宫颈癌淋巴结转移临床价值，以期选择最佳方法，提高临床诊治水平。方法:选取2010年1月-2013年1月46例宫颈癌淋巴结转移患者，对宫颈癌髂总、髂内和髂外、腹总动脉旁淋巴结转移进行诊断，将多层螺旋CT检查数目和淋巴结清扫术病理检查结果进行分析。结果:对多层螺旋CT诊断淋巴结转移敏感性和特异性进行比较，髂总动脉敏感性为88.75%，特异性为68.93%；髂内动脉敏感性为87.67%，特异性为67.56%；髂外动脉敏感性为90.77%，特异性为73.15%；腹主动脉旁敏感性为92.14%，特异性为72.43%。多层螺旋CT诊断淋巴结转移总敏感性为89.83%，总特异性为70.52%。对多层螺旋CT和病理诊断淋巴结转移比较，CT诊断阴性符合率为63.04%，阳性符合率为36.96%；病理阴性符合率为30.43%，阳性符合率为69.57%，两者比较差异无统计学意义（P＞0.05）。结论:多层螺旋CT可作为诊断宫颈癌淋巴结转移的首选诊断方法，其诊断价值较高。

Clinical study of multislice spiral CT in the diagnosis of cervical lymph node metastasis

Objective:To investigate the clinical value of multislice spiral CT in the diagnosis of cervical lymph node metastasis.Methods:All 46 cases of cervical lymph node metastasis in patients with cervical cancer iliac,internal iliac and external iliac,abdominal artery bypass diagnosis of lymph node metastasis,the number of multislice spiral CT examination and lymph nodes dissection pathology results were analyzed.Results:The sensitivity and specificity of multislice CT diagnosis of lymph node metastasis were compared.Sensitivity was 88.75% of the common iliac artery and specificity was 68.93%.Sensitivity was 87.67% of the internal iliac artery and specificity was 67.56%.The external iliac artery sensitivity was 90.77% and a specificity 73.15%.Sensitivity was 92.14% of abdominal aortic artery and specificity was 72.43%.Multislice spiral CT diagnosis of lymph node metastasis overall sensitivity was 89.83%,specificity 70.52%.Multislice spiral CT for the diagnosis of lymph node metastasis and pathological comparison,CT diagnosis of negative coincidence rate was 63.04%,the positive rate was 36.96%.Pathology negative coincidence rate was 30.43%,the positive rate was 69.57%(P＞0.05).Conclusion:Multislice spiral CT can be used as a diagnostic method for cervical lymph node metastasis,with high diagnostic value.
