High-Level Clonal FGFR Amplification and Response to FGFR Inhibition in a Translational Clinical Trial.
Pearson, A; Smyth, E; Babina, IS; Herrera-Abreu, MT; Tarazona, N; et al. (AMER ASSOC CANCER RESEARCH, 2016-08-01)UNLABELLED: FGFR1 and FGFR2 are amplified in many tumor types, yet what determines response to FGFR inhibition in amplified cancers is unknown. In a translational clinical trial, we show that gastric cancers with high-level ... -
