ABSTRACT
Objective To investigate the association of MRI features with HER-2 expression in non-mass-like breast carcinoma. Methods 74 patients with breast cancers diagnosed by pathology underwent MRI prior to surgery,and all lesions were non-mass-like enhancement on dynamic contrast-enhanced MRI.The expression of HER-2 in tumor tissue was detected by immunohistochemical staining.Chi-square test,Fisher’s exact test and spearman rank correlation were used to evaluate the correlations between the morphological characteristics, dynamic enhanced MR parameters,ADC value and HER-2 expression.Results The tumor size was correlated positively with the expression degree of HER-2 (r=0.341,P =0.003).The ADC value was also correlated positively with the positive expression degree of HER-2 (r=0.31 7,P =0.006).However,the time to peak was correlated negatively with that (r =-0.244,P =0.036).No significant correlations between the distribution/internal enhancement manner,the type of time signal intensity curve and HER-2 expression were found (all P >0.05).Conclusion Tumor size,time to peak and ADC value are correlated with the expression of HER-2 in non-mass-like breast carcinoma,which is helpful for the treatment plan and prognosis evaluation for this cancer.
