In 58 of the 73 patients, HLA-C, -DR typing were also studied in addition. The results of this study showed that HLA-Bw61 (40) were negatively associated with BC, while -Cw7 and -DRw6 were positively associated with BC. Moreover, -DR was more closely associated with ER(+) status with a RR value of 8.621. In the ER(-) group, there were no specific related antigens. In the light of the differences in pathology, prognosis and effect of endocrine therapy between ER(+) and ER(-) status, the authors are inclined to the view that the two kinds of breast cancer may be a heterogeneous disease.展开更多
