Targeting ADAMS and ERBBs in lung cancer.

Aberrant ERBB receptor activity contributes to the development of many human cancers. Receptor overexpression, kinase domain (KD) mutations, and autocrine ligand production contribute to ERBB activation in human tumors. ERBB-targeted tyrosine kinase inhibitors (TKIs) and monoclonal antibodies are used in cancer treatment; however, clinical hurdles, including patient selection and TKI resistance, need to be overcome in order to optimize therapy. This minireview will discuss recent findings on possible mechanisms leading to ERBB-targeted therapy resistance and potential means to overcome them.
