Representativeness of the Surveillance, Epidemiology, and End Results Program Data: Recent Trends in Cancer Mortality Rates

摘要: BACKGROUND Mortality, incidence, and survival rates are the primary measures used by National Cancer Institute (NCI) to monitor cancer in United States. The Surveillance, Epidemiology, End Results (SEER) data system collects on all cancers diagnosed among residents geographically defined populations, which comprise about 10% of U.S. population. This is major component NCI for tracking these rates. Thus, it important assess degree SEER representative entire PURPOSE mortality, but not incidence or survival, available from Center Health Statistics. These provide a census against mortality subset regions may be compared. METHODS Multivariate regression analyses age-adjusted 1975 1988, computed areas States, were performed race- sex-specific 15 sites. Representativeness was evaluated testing differences trends levels between population those Program. RESULTS Data reflected correct direction trend sites, although some race-, sex-, site-specific existed magnitude when compared with CONCLUSIONS demonstration that do occasionally yield differ suggests coverage are, cases, greater IMPLICATIONS issue particular relevance interpretation measures, data, there no national database. Future efforts should directed at better understanding how differs so can adjusted more nationally representative.
