Sintilimab Combination Therapy Plus IMRT in Nasopharyngeal Carcinoma

This is a prospective, single-center, single-arm, phase II clinical study. The study was intended to include patients with locoregionally advanced nasopharyngeal cancer identified by histology or cytology, who signed informed consent and met the screening criteria to enter the study. Patients will receive induction therapy (sintilimab + bevacizumab + gemcitabine, Q3W, 3 cycles) followed by IMRT+ Sintilimab. Consolidation therapy with sintilimab continued after radiotherapy until disease progression, intolerable toxicity, death, or the subject's decision to withdraw from the study, with a total treatment period of no more than 12 cycles.
