The 1-year mortality after radiotherapy for nasopharyngeal carcinoma: a population-based analysis.

To assess the incidence and predictors of nasopharyngeal carcinoma (NPC)-specific mortality in the first year among NPC patients. We identified 2714 patients in the SEER program. 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. 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.
