Since our cohort was comprised of patients with different histologic subtypes of HNSCC, we evaluated the association between DCLK1 expression and clinical outcome in patients with oral (n = 86), oropharyngeal (n=65), laryngeal (n=56), and hypopharyngeal (n=15) carcinoma. The gene discussed is DCLK1; the disease is head and neck squamous cell carcinoma.
