What this study is about

Researchers are testing whether combining proton radiation therapy (PT) or photon radiation therapy (XRT) with pembrolizumab, a drug that blocks the PD-1 protein, before surgery can benefit patients with recurrent head and neck squamous cell carcinoma. The trial will also assess if this combination is safe for adults.
