Influence of county-level geographic/ancestral origin on glioma incidence and outcomes in US Hispanics.

Glioma incidence and outcomes differ in association with the geographic origins of Hispanic communities, with counties of predominantly Mexican/Central-American-origin at significantly reduced risk and those of Caribbean-origin at comparatively greater risk. Although typically classified as a single ethnic group, appreciating the cultural, socioeconomic, and genetic diversity of Hispanics can advance cancer disparities research.
