Head and neck oncology is one of the main clinical and research fields in our department. The management of head and neck cancer (HNC) involves the combined-modalities of chemotherapy, radiation therapy and surgery. At the same time, we are designing new treatments aimed at improving treatment outcomes and patients' quality of life and arepromoting clinical research into immunotherapy using NKT cells.
