Significant correlations of the MDR1+ leucocyte infiltrate with the tumor specific antigens human epidermal growth factor receptor 2 (HER2) (cc = 0.258, p = 0.005) and tumor-associated mucin 1 (TA-MUC1) (cc = 0.202, p = 0.022) were found (Table 2), but no further correlations with the above mentioned clinicopathological parameters (Supplementary file Table S2). Here, ERBB2 is linked to neoplasm.
