[The prognostic role of expression of p16 tumor suppressor gene in Hungarian patients with oral squamous cell carcinoma].

Beside smoking and alcohol consumption, human papillomavirus (HPV) infection is the most common risk factor of squamous cell carcinoma in the head and neck region (HNSCC). The latter group of patients associates with better prognosis. During HPV infection, the level of p16 tumor suppressor elevates, which could give an additional opportunity for diagnosis: instead of molecular diagnostic tools, the application of immunohistochemistry is acceptable.
