Does lapatinib work against HER2-negative breast cancers?

Clin Cancer Res. 2010 Mar 1;16(5):1355-7. doi: 10.1158/1078-0432.CCR-09-3223. Epub 2010 Feb 23.

Abstract

Aberrant growth factor receptor signaling can augment or suppress estrogen receptor (ER) function in hormone-dependent breast cancer cells and lead to escape from anti-estrogen therapy. Interruption of HER2/ER cross-talk with lapatinib can restore sensitivity to anti-estrogens and thus, should be investigated in combination with endocrine therapy in patients with ER+/HER2-negative breast cancers.
