Background Most patients with nonsmall-cell lung cancerhave no response to the tyrosine kinase inhibitor gefitinib,which targets the epidermal growth factor receptor (EGFR). However,about 10 percent of patients have a rapid and often dramaticclinical response. The molecular mechanisms underlying sensitivityto gefitinib are unknown.
Methods We searched for mutations in the EGFR gene in primarytumors from patients with nonsmall-cell lung cancer whohad a response to gefitinib, those who did not have a response,and those who had not been exposed to gefitinib. The functionalconsequences of identified mutations were evaluated after themutant proteins were expressed in cultured cells.
Results Somatic mutations were identified in the tyrosine kinasedomain of the EGFR gene in eight of nine patients with gefitinib-responsivelung cancer, as compared with none of the seven patients withno response (P<0.001). Mutations were either small, in-framedeletions or amino acid substitutions clustered around the ATP-bindingpocket of the tyrosine kinase domain. Similar mutations weredetected in tumors from 2 of 25 patients with primary nonsmall-celllung cancer who had not been exposed to gefitinib (8 percent).All mutations were heterozygous, and identical mutations wereobserved in multiple patients, suggesting an additive specificgain of function. In vitro, EGFR mutants demonstrated enhancedtyrosine kinase activity in response to epidermal growth factorand increased sensitivity to inhibition by gefitinib.
Conclusions A subgroup of patients with nonsmall-celllung cancer have specific mutations in the EGFR gene, whichcorrelate with clinical responsiveness to the tyrosine kinaseinhibitor gefitinib. These mutations lead to increased growthfactor signaling and confer susceptibility to the inhibitor.Screening for such mutations in lung cancers may identify patientswho will have a response to gefitinib.
