Abstract

Molecular targeting drugs (MTG) have proved effective for head and neck cancer (HNC) not only in basic studies but in many clinical trials. Cetuximab, an anti-EGFR monoclonal antibody, is a key drug for regimens including MTG. However, monotherapy with cetuximab has shown limited success. Molecular crosstalk has been observed between EGFR and IGF1R signaling through the PI3kinase/Akt pathway, as has molecular crosstalk between the NFkappaB and STAT3 signaling pathways. Therefore, the combination of cetuximab with an agent that inhibits the activation of both Akt and STAT3 may overcome resistance to cetuximab in HNC.
