KRT8 and carcinoma: In a last step, we assessed the expression of K8 in carcinomas (n = 102) of various localizations including hypopharynx (n = 10), oro-hypopharynx (n = 2), larynx (n = 23), oropharynx (n = 13), larynx-hypopharynx (n = 2), vocal cords (n = 2), mouth (n = 6), tonsil (n = 15), valecula (n = 13), and tongue (n = 16).
