Different mutation profiles and clinical characteristics among Hispanic patients with non-small cell lung cancer could explain the “Hispanic paradox”

The high frequency of EGFR mutations and low frequency of KRAS mutations in Hispanic populations and different prevalence in lung cancer-related-developing risk factors compared with Caucasian populations, such as the lower frequency of smoking exposure and higher WSE, particularly in women, might explain the prognosis differences between foreign-born-Hispanics, US-born-Hispanics and NHWs.
