摘要
目的探讨多层螺旋CT(MSCT)增强扫描对乳腺癌患者腋窝淋巴结转移的诊断价值。方法收集2019年2-9月于该院行乳腺MSCT增强扫描的83例非特殊类型浸润性乳腺癌患者,根据病理结果,分为腋窝淋巴结转移(ALNM,n=41)和非转移(ALNN,n=42)两组。对患者临床特征、MSCT形态学特征及CT值进行统计学分析,并对动脉期、静脉期CT值进行ROC曲线分析,评价诊断效能。结果两组患者的年龄、病灶最大径及位置、有无毛刺征及分叶征、边界情况等指标差异无统计学意义(P>0.05);ALNM组肿瘤的动脉期及延迟期CT值均高于ALNN组,差异有统计学意义(P=0.031、0.020);肿瘤动脉期及延迟期CT值及两者联合诊断腋窝淋巴结转移的AUC分别是0.673、0.639和0.663;当动脉期CT值大于47 HU时,诊断淋巴结转移的灵敏度为92.68%,特异度为54.76%。结论MSCT增强扫描对乳腺癌患者腋窝淋巴结转移具有一定的价值,其中肿瘤动脉期CT值诊断腋窝淋巴结转移的效能最佳。
Objective To investigate the diagnostic value of multi-slice spiral computed tomography(MSCT)enhanced scan for axillary lymph node metastasis in breast cancer patients.Methods A total of 83 patients with non-specific invasive breast cancer who underwent MSCT enhanced breast scan in the hospital from February 2019 to September 2019 were collected.Based on the results of pathology,patients were divided into two groups:the axillary lymph node metastasis group(ALNM,n=41)and the nonmetastatic group(ALNN,n=42).The clinical characteristics,morphological characteristics of MSCT and CT value of the patients were statistically analyzed,and the CT value of arterial and venous phase were analyzed by ROC curve to evaluate the diagnostic efficiency.Results There were no significant differences in age,lesion diameter,location,burr sign,lobulation and border between the two groups.The CT values of arterial phase and parenchymal phase in the ALNM group were higher than those in the ALNN group,and the differences were statistically significance(P=0.031;P=0.020).The CT value of the arterial phase and the parenchymal phase,and the AUC of the combined diagnosis of axillary lymph node metastasis were 0.673,0.639,and 0.663,respectively.When the CT value of arterial phase was greater than 47HU,the sensitivity and specificity of lymph node metastasis were 92.68%and 54.76%respectively.Conclusion The CT value of MSCT enhanced scan in different periods has a certain value for axillary lymph node metastasis in breast cancer patients.The CT value of the arterial phase is the best for the diagnosis of axillary lymph node metastasis.
