Cancer among Hispanic males in south Florida. Nine years of incidence data

Dade County (Florida) is the largest county in the United States in which a majority of the population is Hispanic. To describe and compare cancer incidence among white and black Hispanic and non-Hispanic males in South Florida and to identify those sites showing important racial-ethnic differences between sub-groups, incidence rates were determined from 9 years of prospective population-based cancer surveillance data.

All incident cancer cases diagnosed among male residents of Dade County for the period January 1, 1981, through December 31, 1989, were obtained from the statewide tumor registry for Florida, the Florida Cancer Data System. Race- and ethnic-specific age-standardized incidence rates and standardized rate ratios to compare rates among racial-ethnic subgroups for each site are presented.

Compared with white non-Hispanics, white Hispanic males had significantly higher rates of cancers of the liver, gallbladder, nasal cavity, penis, and thyroid; acute lymphocytic leukemia; and Kaposi's sarcoma. Significantly lower rates were found for cancers of the esophagus, stomach, colon, rectum, pancreas, lung, testes, bladder, and kidney, and for mesothelioma, melanoma, non-Hodgkin's lymphoma, and chronic lymphocytic leukemia. Black Hispanics had significantly lower rates only of cancers of the esophagus, lung, and prostate than did black non-Hispanics.

Differences were found in incidence rates by race-ethnicity; while incidence rates for most sites among white Hispanic males were lower than among white non-Hispanics, higher rates for several sites are of particular concern and merit further investigation to determine differences in risk factors and exposures.
