The investigatorsdesigned a multi-center, single-arm, small sample clinical pilot study. In the clinical trial, patients were given regimes of induction therapy with PLPF (Pembrolizumab + Low dose- P (Platinum) F (5-Fluorouracil)): 6 cycles of Pembrolizumab treatment. Herein, the investigators describe eight consecutive unselected LA SCCHN (Locally Advanced Head and Neck Squamous Cell Carcinoma) patients based on 6 completed cycles of PLPF induction therapy.
