Immunotherapy in head and neck cancer: current practice and future possibilities.

The survival of patients with head and neck squamous cell carcinoma has changed little over the last 30 years. However, with recent advances in the fields of cellular and molecular immunology, there is renewed optimism with regards to the development of novel methods of early diagnosis, prognosis estimation and treatment improvement for patients with head and neck squamous cell carcinoma.
