Phase III Non-Inferiority Trial of Proton Versus Photon Therapy for Nasopharyngeal Carcinoma

This study is a prospective, open-label, multicenter, cohort, phase III non-inferiority clinical trial comparing proton therapy with photon radiotherapy for nasopharyngeal carcinoma. It intends to enroll histologically confirmed newly diagnosed nasopharyngeal carcinoma patients without distant metastasis (M0). Through a prospective 1:1 matched cohort study design, patients will be divided into the intensity-modulated proton therapy (IMPT) group and the intensity-modulated radiation therapy (IMRT) group. Systemic treatment regimens are formulated according to clinical guidelines.
