The most common histology of non-thyroid head and neck cancer is squamous cell carcinoma. Common risk factors for head and neck malignancies include tobacco and alcohol abuse and viruses, including Epstein-Barr Virus (EBV) and Human Papillomavirus (HPV). Early stage disease is often treated with surgery or radiation therapy alone, while more advanced disease often requires a multi-modality approach including systemic chemotherapy, radiation, and surgical resection. In the curative setting, current clinical trials are evaluating the de-escalation of therapy in HPV-releated head and neck cancer. In the metastatic setting, clinical trials have focused on using immunotherapy agents to improve outcomes. This review chapter will discuss the etiology and common presentations of head and neck cancer, and also analyze recent advancements in the treatment of the disease.
