HNSCC and Immunotherapy: The Beginning of a Long Story

The immunotherapy revolution has not spared Head and neck squamous cell carcinoma (HNSCC). Checkpoint inhibitors (anti-PD-1 / PD-L1) were the first to be validated in second line treatment and soon come to the first line in local or metastatic recurrence. Many studies are currently underway to expand the indications of these new therapies, whether as monotherapy or in combination. In addition, immunotherapy is not limited to checkpoint inhibitors and many other immunotherapy molecules are currently under study. The selection of patients who benefit from immunotherapy and the evaluation of the response to these treatments are problems not completely solved. The aim here is to present the state of art on immunotherapy in HNSCC.
