FGFR3 and head and neck squamous cell carcinoma: In head and neck squamous cell carcinoma (HNSCC) that was positive for human papilloma virus (HPV, 42.5% of 120 tumor samples), genomic analysis using parallel sequencing technology revealed nearly 18% of tumors with mutations in FGFR2 or FGFR 3, which was notably different than in HPV negative samples [54].
