Abstract:
Objective To observe the value of Node-RADS based on dynamic contrast-enhanced MRI(DCE-MRI)for assessing axillary lymph node metastasis of breast cancer.Methods A total of 308 patients with breast cancer were retrospectively enrolled and divided into metastasis group(n=153)and non-metastasis group(n=155)based on the presence of axillary lymph node metastasis or not.Two radiologists independently scored the axillary lymph nodes shown on DCE-MRI according to Node-RADS criteria.Inter-observer scores was assessed using Kappa test.Taken pathological result as the gold standard,receiver operating characteristic curves were plotted,and the area under the curve(AUC)was calculated to evaluate the efficacy of Node-RADS scores for diagnosing axillary lymph node metastasis.Results Good inter-observer consistency of Node-RADS scores was observed.When Node-RADS score＞2,the highest AUC of 2 radiologists was 0.928 and 0.921,respectively,being not significantly different(P＞0.05).Conclusion Node-RADS based on DCE-MRI had good efficacy for evaluating axillary lymph node metastasis of breast cancer.Node-RADS score higher than 2 strongly indicated possibility of lymph node metastasis.
