FFDM differential diagnosis of mastitis,benign hyperplasia and breast cancer / 实用肿瘤学杂志

ABSTRACT

Objective The aim of this study was to investigate FFDM differential diagnosis between breast mastitis,benign hyperplasia and breast cancer. Methods Fifty-nine cases of non-puerperal breast mastitis,sixty-eight cases of benign hyperpla-sia and two hundred and forty cases with non-mass type breast cancer were analyzed retrospectively,which were verified by surgery and pathology by contrast with FFDM signs,pathological types,grouped and statistics processed. The observation indexes of lamellar shadow included shape,density and edge. The observation indexes of linear shadow included direction,form and diameter. Results The FFDM signs in three groups of breast diseases were statistically significant(P<0. 05)the form of linear shadow,accompanied by calcifications,the shape of lamellar shadow,the direction of linear shadow,the distribution of lesion,the sharp angle of shadow edge. χ2 segmentation show that there were significant differences between three groups(P<0. 0125)the shape of lamellar shadow,the direc-tion of linear shadow. Conclusion There have some values for the diagnosis of breast cancer by rigid form and radial distribution of linear shadow,rigid shape and segmental distribution of lamellar shadow,the polymorphic calcifications and the sharp angle sign.
