Our recent report showed that combined treatment with lapatinib, a dual inhibitor of EGFR and ErbB2/HER2, and imatinib, a c-ABL inhibitor, resulted in synergistic growth inhibition in a panel of EGFR/ErbB2-expressing breast cancer cells including the TNBC cell line MDA-MB-468 [17]. This evidence concerns the gene ERBB2 and breast cancer.
