Prevalence of fibroblast growth factor receptor 1 (FGFR1) amplification in squamous cell carcinomas of the head and neck

摘要

FGFR1 is a receptor tyrosine kinases involved in tumor growth signaling, survival, and differentiation in many solid cancer types. There is growing evidence that FGFR1 amplification might predict therapy response to FGFR1 inhibitors in squamous cell lung cancers. To estimate the potential applicability of anti FGFR1 therapies in squamous cell carcinomas of the head and neck, we studied patterns of FGFR1 amplification using fluorescence in situ hybridization (FISH).
