摘要

The epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor-2 (HER2) have been intensely scrutinized as therapeutic targets in cancer because of the relationship between overexpression of these receptors and poor prognosis. In general, targeting EGFR or HER2 can be accomplished with antibodies directed against the receptor extracellular domains or with small-molecule inhibitors of the intracellular tyro-sine kinase domains. Although both strategies have been clinically promising, considerable variability in efficacy has also been noted; this raises important questions about the molecular basis for drug responsiveness. Moreover, an improved understanding of the mechanisms of action of agents that target the HER family may open new avenues of research into therapeutic resistance and offer patients additional treatment options.
