In particular, amplification of FGFR1 located at 8p11-12, resulting in overexpression, occurs in less than 10% across all breast cancer subtypes [2], in approximately 10–16% of luminal-type breast cancers [3,4,5,6], and 4% in triple-negative breast cancer [7]. This evidence concerns the gene FGFR1 and breast carcinoma.
