Other reports implicating PI3K mutations in HER2 resistance have only been in vitro or are very small cohorts of patients [107]. The proposed main resistance mechanisms related to HER2-directed therapy are given in Table 5. Theoretically, in addition to tumor heterogeneity, resistance to trastuzumab may be caused by altered receptor-antibody interaction, compensatory activation of the downstream pathways by increased signaling from either other members of the HER family or other receptors, or constitutive activation of downstream elements [108, 109].

Lapatinib is an orally administered small molecule inhibitor that targets both EGFR and HER2 [112]. It targets the tyrosine kinase domain of these receptors by reversibly binding to the adenosine triphosphate binding site of the kinase, as illustrated in Figure 2. This interaction prevents the phosphorylation and subsequent signal transduction of both the MAPK and the PIK-3/Akt pathways, leading to an increase in apoptosis and decreased cellular proliferation. In addition to inhibiting wild-type HER receptors, lapatinib is able to inhibit truncated forms of these receptors [113].
