Ethnic differences in uterine corpus cancer incidence and mortality in New Mexico's American Indians, hispanics and non-Hispanic whites.
BACKGROUND
Although ethnic and radical differences in uterine corpus cancer incidence and mortality have been reported worldwide, few published data have addressed the epidemiology of uterine cancer among US American Indians and Hispanics.


METHODS
We reviewed uterine corpus cancer incidence and survival data from New Mexico's population-based cancer registry collected from 1969 to 1992, and examined State vital records data for uterine cancer deaths collected from 1958 to 1992, focusing on ethnic differences in occurrence and outcomes of uterine malignancies.


RESULTS
Non-Hispanic white women had age-adjusted incidence rates that were substantially higher (20.8 per 100,000) than rates for Hispanics (10.3) and American Indians (6.0) over the 24-year period. Uterine cancer mortality rates were also higher for non-Hispanic whites and Hispanics than for American Indian women, although mortality rates were substantially lower than incidence rates. Five-year survival for uterine cancer was comparable among all groups for all stages combined (87.3% for non-Hispanic whites, 81.4% for Hispanics, and 84.6% for American Indians).


CONCLUSIONS
Our population-based data show ethnic differences in uterine corpus cancer incidence rates for non-Hispanic white women that were double those for Hispanics, and triple those for American Indian women. Ethnic differences in survival were comparable. Aetiologic studies are warranted to investigate the dramatic ethnic differences in occurrence of uterine cancer.
