Background: Oral cavity cancer (OCC) and laryngeal cancer cancer survival for NH White, NH Black, Hispanic, and Asian are among the most common cancers worldwide. This study patients. In the multivariable analyses of both OCC and laryngeal investigated survival in non-Hispanic (NH) Black, NH White, cancer survival, NH Black patients had worse survival than NH Asian, and Hispanic patients with OCC and laryngeal cancer of White patients in the high nSES tertile. NH Black patients with OCC low, intermediate, and high neighborhood socioeconomic status were at higher risk of death than NH White patients at all nSES (nSES). levels.
