J. Guillermo Paez, Pasi Antero Janne, Jeffrey C. Lee, Sean I. Tracy et al.

Short summary

Somatic mutations in the EGFR gene predict sensitivity to the EGFR inhibitor gefitinib in non-small cell lung cancer (NSCLC).

AI-generated from the title and abstract; the full text is not read.

Key points

  • EGFR somatic mutations found in 15/58 Japanese and 1/61 US NSCLC tumors.
  • EGFR mutations present in gefitinib-responding NSCLC patients and hypersensitive cell lines.
  • EGFR mutations absent in gefitinib-insensitive tumors and cell lines.
  • EGFR mutations may predict sensitivity to gefitinib therapy.

Abstract

Receptor tyrosine kinase genes were sequenced in non-small cell lung cancer (NSCLC) and matched normal tissue. Somatic mutations of the epidermal growth factor receptor gene EGFR were found in 15of 58 unselected tumors from Japan and 1 of 61 from the United States. Treatment with the EGFR kinase inhibitor gefitinib (Iressa) causes tumor regression in some patients with NSCLC, more frequently in Japan. EGFR mutations were found in additional lung cancer samples from U.S. patients who responded to gefitinib therapy and in a lung adenocarcinoma cell line that was hypersensitive to growth inhibition by gefitinib, but not in gefitinib-insensitive tumors or cell lines. These results suggest that EGFR mutations may predict sensitivity to gefitinib.
