Aim: To assess the incidence and predictors of nasopharyngeal carcinoma (NPC)-specific mortality in the first year among NPC patients. Methods: We identified 2714 patients in the SEER program. Results: Of the patients, 151 (5.6%) patients who died as NPC-related disease within 1 year of diagnosis. Specifically, 67.5% of the NPC-related deaths were attributed to keratinizing tumors, while 67.6% were attributed to advanced T stage. Older age, keratinizing squamous tumors and stage T3-4 disease were independent predictors of 1-year NPC-related death. Conclusion: The 1-year mortality rate is low among NPC patients after radiotherapy. Older age, keratinizing tumor and advanced T stage are predictors of high-mortality risk within 1 year in NPC patients.
