Fig. 3From: Prognostic implications of Fibroblast growth factor receptor 1 (FGFR1) gene amplification and protein overexpression in hypopharyngeal and laryngeal squamous cell carcinomaKaplan-Meier survival curves for FGFR1 gene amplification (a and b) and protein overexpression (c and d) in hypopharyngeal and laryngeal squamous cell carcinoma. FGFR1 amplification was significantly associated with disease-free survival (a) but not overall survival (b). FGFR1 protein overexpression was not related to disease-free survival (c) or overall survival (d)Back to article page
