Head and neck squamous cell carcinoma (HNSCC) treatment is often associated with high morbidity especially in the recurrent and/or metastatic (R/M) setting, limiting effective treatment options. Local disease control is important. Therefore, local therapies including reirradiation and salvage surgery, either alone or in combination with systemic treatment, may be used for selected patients with R/M HNSCC. Although chemotherapy and targeted agents have modest efficacy in HNSCC, the advent of immunotherapy has revolutionized the treatment paradigm of R/M HNSCC. Multiple trials have resulted in the past 5 years advocating for its use alone or in combination with chemotherapy.
