Gene amplification of EGFR has been described in oligodendrogliomas (Fallon et al, 2004), glioblastomas (Marquez et al, 2004), lung carcinomas (Baselga and Arteaga, 2005; Giaccone, 2005), gastric carcinomas (Takehana et al, 2003), and recently, in breast carcinomas (Al-Kuraya et al, 2004). This evidence concerns the gene EGFR and glioblastoma.
