Abstract:
Objective To analyze triple receptor-negative breast cancer (TNBC) and non-triple receptor-negative breast cancer (non-TNBC),to determine the MR imaging characteristics of TNBC.Methods Data from two groups TNBC and non-TNBC patients were reviewed.Recorded the MRI features which involved the morphological features,kinetic lesion features and measured ADC values,As well as their clinical features and the pathological findings.Data were statistical analyzed in SPSS 17.0 software.Results There were significant difference between TNBC and non-TNBC in histological types,histologic grade,the situation of lymph metastases and mass shape,margin subgroup and lesion enhanced type,the ADC value (P ＜ 0.05).The special histological types for TNBC were squamous carcinoma (metaplastic carcinomas),medullary carcinoma,basal-like carcinoma.The number of lymph node metastasis in the TNBC group was 78.9 ％ (15/19).Histologically,TNBC were mainly Ⅲ grade (89.4 ％).In the group of TNBC,the percent of lobulated mass,margin smooth and rim enhancement was 52.6 ％,36.8 ％,42.1％,the higher ADC value of TNBC than non-TNBC.While there were no statistical significant differences in the age of onset,the maximum tumor diameter,the situation of menstruation,the situation of family history of breast cancer,the number of the mass,enhancement lesion type and the time-signal intensity curve type (P ＞ 0.05).Conclusion Some MRI features combined clinical and histopathological characteristics would be helpful in the diagnosis of TNBC.
