RecruitingPhase 3Drug trialHead and Neck Cancer Study Project in the Geriatric PopulationThis is a study conducted in patients with a diagnosis of stage IB-IVA squamous cell carcinoma of the head and neck. Patients will have a comprehensive geriatric assessment (CGA) as part of standard assessments. The patients classified as frail, with a CGA score of 3-5, will then be treated with a novel reduced intensity regimen. The regimen will be tailored based on the programmed cell death ligand 1 combined positive score (PD-L1 CPS) and will involve 4 cycles of systemic chemotherapy and/or immunotherapy followed by radiation treatment.
