BACKGROUND: Non-nasopharyngeal head and @entity135 (LELC) is a rate entity. The purpose of this study was to analyze its demographic, clinicopathologic, and survival characteristics. METHODS: A cohort from the Surveillance, Epidemiology, and End Results (SEER) database of cases with non-nasopharyngeal head and neck LELC between 1973 and 2011. RESULTS: There were 378 cases with 5-year overall survival (OS) of 70.5% and @entity66 ( @entity66 ) of 77.7%. The majority of cases were <60-year-old white @entity1 . Salivary gland LELC had the highest OS (80.8%) and @entity66 (85.7%) at 5 years. Multivariate analysis showed that older age, no surgery, and no radiation were independently significantly associated with worse survival (p < .05). CONCLUSION: Non-nasopharyngeal head and neck LELC is uncommon in the United States with salivary gland LELC having the highest OS and @entity66 compared with other head and neck sites. The optimal treatment with surgery and/or radiotherapy needs to be further investigated.    2015 Wiley Periodicals, Inc. Head Neck 38: E1294-E1300, 2016.
