Plain-language summary
This phase II randomized trial evaluates PD-1 inhibitor plus chemotherapy followed by immediate versus selective re-irradiation in locally advanced recurrent nasopharyngeal carcinoma. The study aims to determine whether sequential radiotherapy provides additional survival benefit beyond systemic immunochemotherapy.
