  1. Tissues from 74 patients with breast cancer were studied, and included the samples of the tumour and corresponding normal breast tissue samples from each patient. Tumors were characterized as TN (n = 11) or EP + H- (n = 49). The p-values were calculated during comparisons between the TN and EP + H- tumors. The Mann-Whitney U-test was used for comparisons of the median age and tumor size. The chi-square test was used for comparisons of histological type, histological grade, lymph node involvement, and disease stage
