tisleilizumab (pd-1 antibody) and chemoradiotherapy in locoregionally-advanced nasopharyngeal carcinoma

Conditions: Nasopharyngeal Neoplasms

Summary: this trial intends to enroll patients with t4n1 or t1-4n2-3 (ajcc 8th) locoregionally-advanced nasopharyngeal carcinoma (lanpc). all the patients will receive 3 cycles of induction chemotherapy with docetaxel and cisplatin and cisplatin based concurrent chemoradiotherapy (ccrt) plus adjuvant immunotherapy (tisleilizumab). all patients will receive intensity-modulated radiotherapy (imrt). tisleilizumab will begin 4-6 weeks after ccrt and continue every 3 weeks for 12 cycles.
