Middle digestive cancers in Texas Hispanics: a New World syndrome?
To test the hypothesis that middle digestive cancers in Texas Hispanics follow the patterns predicted by the New World Syndrome (1984), cancer incidence rates and relative risks for middle digestive cancers were estimated for 1944-1992. The relative risk for all middle digestive cancers is significantly elevated in Texas Hispanics compared with Anglos, and this risk has increased over time. Elevated risks of these cancers in Texas Hispanics have been explained as resulting from the evolutionary history of Native Americans (American Indians), their genetic relation to Texas Hispanics, and a changing diet and lifestyle. Recent Texas cancer incidence data add further support to the hypothesis. Other current disease prevalence data in Texas Hispanics, percent of the population which is diabetic and percent which is overweight, are also consistent with the New World Syndrome. Expected patterns of disease in males vs females are also confirmed. Factors that do not support the New World Syndrome hypothesis and can be examined by future studies are described. This is the first report since the original describing and updating patterns of middle digestive cancers in Texas Hispanics as resulting from the New World Syndrome. Application of these findings to contemporary medical practice and to cancer prevention are reviewed.
