FGFR1 and squamous cell lung carcinoma: As mentioned above, we did not find tail-to-tail rearrangements within the FGFR1 gene itself or genomic evidence of ectodomain-deficient versions of the FGFR1 kinase that we had observed in the patients with a response to FGFR inhibition, as well as in the cohort of untreated squamous cell lung carcinomas (see above).
