GAPP Induction and Concurrent Chemoradiotherapy for High-risk Locoregionally Advanced NPC.

The investigators have designed a multicenter, open-label, randomized controlled phase III clinical study of GAPP induction therapy followed by concurrent chemoradiotherapy and toripalimab maintenance therapy for high-risk locoregionally advanced nasopharyngeal carcinoma (stage III, AJCC 9th edition). The aim is to obtain high-level, high-quality evidence-based data to clarify the efficacy and safety of combining chemoradiotherapy with PD-1 antibody and anlotinib, thereby providing a new treatment strategy to improve the prognosis of patients with high-risk locoregionally advanced nasopharyngeal carcinoma. In this study, GPP induction chemotherapy followed by concurrent chemoradiotherapy and toripalimab maintenance therapy is selected as the control group. This regimen is currently the standard treatment recommended by guidelines for high-risk locoregionally advanced nasopharyngeal carcinoma, with well-established efficacy and broad clinical application. It provides a reliable benchmark for comparing the efficacy and safety of the experimental group, meets ethical requirements, and has mature clinical operational procedures.
