[Immunotherapy for head and neck squamous cell carcinoma].

Current recommendations for systemic treatments of head and neck squamous cell carcinoma have been significantly modified with the advent of immunotherapy for a majority of these cancers. Indeed, immune checkpoint inhibitors are now recommended in metastatic disease and in locoregional recurrence not amenable to a local treatment. PD-L1 positive tumours are eligible for immunotherapy in first line and immunotherapy is also available in second line, after failure of platinum based chemotherapy, regardless of PD-L1 expression. Ongoing clinical trials are exploring the role of immune checkpoint inhibitors in the adjuvant setting as well as with radiotherapy as definitive treatment. Immunotherapy has changed the treatment landscape and has improved the prognosis of patients with head and neck squamous cell carcinoma.
