Evaluation of Axillary Lymph Node Status in Patients with Breast Cancer by CT Scan Combined with Ultrasonography
Objective To investigate the diagnostic value of CT scan combined with ultrasonography in the diagnosis of axillary lymph node status in breast cancer patients.Methods A total of 100 breast cancer patients were collected as the re-search objects.CT scans and ultrasonography were performed under the condition of double-blind CT,ultrasonographers and pa-tients.The results of pathological examination were the gold standard to evaluate the accuracy,specificity and sensitivity of CT,ul-trasound and their combined diagnosis.The receiver operating characteristic(ROC)curve was drawn to evaluate the diagnostic value of CT,ultrasound and their combined examination.Results The diagnostic sensitivity,specificity and accuracy of CT in the diagnosis of axillary lymph node metastasis in 100 breast cancer patients in this group were 83.82％,75.00％and 81.00％,re-spectively,and there was no significant difference compared with 85.29％,75.00％and 82.00％of ultrasonography,both of which were lower than 95.59％,93.75％and 95.00％of the combined examination,and the differences were statistically signifi-cant(P＜0.05).The AUC of CT,ultrasonography and their combined examinations for the diagnosis of axillary lymph node metas-tasis in breast cancer patients in this group were 0.704,0.717 and 0.818,respectively,and the Youden index was 0.38,0.29 and 0.43,respectively.Conclusion CT scan combined with ultrasonography has the highest diagnostic performance for axillary lymph node status in breast cancer patients,and its accuracy,sensitivity and specificity are significantly improved.
