Research Abstract

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have great effect in the treatment of lung cancer patients with EGFR mutation. But many of the patients eventually get worsened (become 'resistance') within one year. It is important to overcome the 'EGFR-TKI-resistance'.
Using lung cancer cell lines, we had elucidated that fibroblast growth factors (FGFs) and receptors (FGFRs) had related to the EGFT-TKI resistance. Using clinical specimens, high FGF9 expression is related to poor prognosis in lung cancer patients. Overexpression of FGF in lung epithelial cell induced transformation, and the tumor formation in immune-deficient mouse was accelerated. FGFR-inhibitor blocked that tumor formation. Using cell lines and clinical specimens, we have comprehensively revealed that FGF/FGFR pathway has an important role in prognosis, tumor formation, and resistance in lung cancer, suggesting that FGF/FGFR pathway can be possible drug target.
