Research Abstract |
Epidermal growth factor (EGFR) tyrosine kinase inhibitors, gefitinib and erlotinib were approver for treatment of lung cancers. In 2004, we collaborated with Dana Farber Cancer Institute and found the EGFR somatic mutations at kinase domain from lung cance samples. The mutations were correlated with gefitinib sensitivity in vitro and in vivo. We have established the sensitive genotyping assays (Taq-Man; Lung cancer : 2005: 50: 375-384 and LightCycler; Cl in Cancer Res: 2005: 11: 2924-2929) to detect these EGFR mutations from clinical samples. Using these assays, we have evaluated the mutation status and clinico-pathological background. We have also evaluated the EGFR mutations at exon 20, as known as resistant mutant for gefitinib therapy. We have also performed the FISH analysis to examine the EGFR amplification status. ErbB3 and erbB4 expression and mutation were also examined, however, we did not find and erbB3 or erbB4 mutation. We have cont inued the collaboration with Dana Farber Cancer Institute and using the SNP array, we examined the gene mutation statuses for large scale lung cancer samples. The results were published at Nature Genetics (2007: 39: 347-351)
