Some cancers appear to acquire resistance to EGFR inhibitors, and multiple mechanisms seem to underlie the lack of sensitivity to the targeted therapies, including mutations in the EGFR gene itself, as well as in down-stream effectors such as RAS, RAF, and AKT that appear to be associated with differential clinical outcomes. +. are Cell lines were generated that expressed either wild-type EGFR or one of two recurrent mutations detected in tumors from gefitinib-responsive patients: the missense mutation Leu 858 → Arg 858 (L858R) and the 18–base pair inframe deletion, delL747-P753insS (fig.
