Nasopharyngeal cancer mortality in disaggregated Asian and non‐Asian Americans

Background Nasopharyngeal carcinoma (NPC) mortality varies based on multiple risk factors. While NPC mortality is higher in Asia, little is known about Asian subgroups in the United States (US). Methods Using the 2005–2020 National Vital Statistics System, we examined NPC mortality by age, race (non‐Hispanic black, Hispanic white (HW), non‐Hispanic white (NHW), Chinese, Filipino, Asian Indian, Japanese, Korean, Vietnamese), sex, and nativity (Untied States or foreign‐born). Results Upon disaggregation, Chinese (1.96 [CI: 1.78–2.16]), Filipino (0.68 [0.68–1.11]), and Vietnamese Americans (0.68 [0.52–1.10]) had the top age‐adjusted mortality rates (AAMR per 100 000 person‐years). Foreign‐born Chinese, Vietnamese, Filipinos, Asian Indians, and NHW had higher AAMRs compared to US‐born persons. All male groups had higher AAMR compared to females. Stratifying for race, nativity, and sex, foreign‐born Chinese males (4.09 [3.79–4.40]) had the highest AAMR. Conclusion These findings demonstrate the importance of disaggregating NPC mortality data by Asian subgroups, providing valuable insights for targeted public health interventions in the United States.
