RÉSUMÉ

Objective To investigate the correlation of DCEGMRI findings with pathologic tumor response to neoadjuvant chemotherapy for patients with tripleGnegative breast cancer (TNBC).Methods SixtyGnine patients with TNBC were enrolled,who underwent DCEG MRI before neoadj uvant chemotherapy,then completed neoadjuvant chemotherapy and surgery.Patterns of tumor volume reduction were divided into two types.Univariate and multivariate Logistic regression analyses were performed to detect the independent predictors of pathological tumor response.Results 30.4% (21/69)patients achieved a pathologic complete response.Multivariate Logistic regression analysis showed that homogenous enhancement on preGneoadj uvant chemotherapy MRI (OR=1 0.87 ,9 5%CI=2.94-48.3 1 ,P<0.00 1 )and concentric shrinkage pattern on postGneoadj uvant chemotherapy (OR=1 3.04,9 5%CI=2.0 1-54.1 1 ,P<0.00 1 )were the independent predictors of pathologic complete response.Conclusion Homogeneous enhancement on preGneoadj uvant chemotherapy MRI and the presence of concentric shrinkage pattern are correlated with pathologically complete response in patients with TNBC.
