Patterns of recurrence in head and neck squamous cell carcinoma to inform personalized surveillance protocols

After treatment for head and neck cancer (HNC), patients are at risk of recurrence at prior sites of disease or at distant sites in the body. This study includes a large group of patients with recurrent or metastatic HNC and examines factors associated with survival outcomes and recurrence patterns. Patients with human papillomavirus (HPV)-positive HNC have good survival outcomes, but if they recur, this may be in distant regions of the body and may occur later than HPV-negative patients. These data argue for personalized follow-up schedules for patients with HNC, perhaps incorporating imaging studies or novel blood tests.
