Figure 1. Targetable Pathways in HNSCC.
Currently FDA-approved targeted agents are limited to cetuximab (EGFR antibody), pembrolizumab and nivolumab (PD-1 antibodies). Additional targetable and commonly mutated pathways include other members of growth factor receptor families, Ras-MAPK and JAK/STAT downstream signaling pathways, PI3K, and downstream effectors of Notch1.
