Prediction of nipple areola complex invasion in breast cancer patients based on ultrafast dynamic contrast-enhanced MRI
摘要
Abstract
Objective:To explore the predictive value of ultrafast dynamic contrast-enhanced magnetic resonance imaging(UF DCE-MRI)in evaluating the invasion of nipple areola complex(NAC)in breast cancer patients.Methods:A retrospective analysis was conducted on the breast cancer patients examined by UF DCE-MRI in our hospital.The patient's clinical patho-logical information,imaging features and the dynamic parameters were analyzed between groups.Logistic regression was used to construct a prediction model for NAC invasion in breast cancer.The diagnostic efficacy of the model was evaluated using re-ceiver operating characteristic curves(ROC).Results:The maximum tumor diameter was significantly larger in the NAC-invaded group than in the non-invaded group(P<0.001).The rates of NAC early enhancement and axillary lymph node metastasis were significantly higher,while the rate of non-enhancement was significantly lower,in the NAC-invaded group compared to the non-invaded group(P<0.001).The Ktrans and Ve values in the invaded group were significantly lower than those in the non in-vaded group,and the kep and MS values in the invaded group were significantly higher than those in the non invaded group(P<0.05).Multivariate Logistic regression analysis showed that NAC enhancement pattern,Ktrans,kep and MS were independent pre-dictors of NAC invasion,the area under the ROC curve(AUC)was 0.89.The sensitivity and specificity were 82.91％and 81.82％,respectively the cut-off value was 0.58.Ktrans had the highest contribution(SHAP value=32.4％).Conclusion:The pre-dictive model for NAC invasion in breast cancer based on UF DCE-MRI has high diagnostic efficacy.关键词
