RESUMO
International statistics suggest lower cancer incidence in the Middle East and Middle Eastern (ME) immigrants in Europe, Australia, and Canada, but little is known from the United States. This study compares cancer rates in ME population with other race/ethnic groups in California from 1988 through 2004. ME cases in California cancer registry were identified by surname and ME population was estimated from U.S. Census data. Cancer rates for ME countries was obtained from Globocan. The ME incidence rate ratios for all sites combined in male and female were 0.77 and 0.82, respectively and were statistically significant. ME rates were significantly lower for cancers of the colon, lung, skin melanoma, female breast and prostate, and were significantly higher for cancers of the stomach, liver, thyroid, leukemia, and male breast. Cancer incidence in ME population in California was 2.4 times higher than rates in home countries. Incidence trends in ME males remained fairly stable but in females shows a slight decline in recent years. Cancer incidence in ME population is lower than non-Hispanic white and non-Hispanic Black, but is higher than rates for Hispanics and Asians, and ME countries. Improved data quality, chronic infections, acculturation, and access to screening services are some of the factors responsible for the observed pattern.
