Incidence and Descriptive Epidemiology of Mesothelioma in the United States, 1999-2002

To estimate the recent incidence of mesothelioma in the United States and characterize its descriptive epidemiology, incidence data were obtained from the National Program of Cancer Registries (NPCR) and the Surveillance, Epidemiology and End Results (SEER) Program. Age-adjusted incidence rates and 95% confidence intervals were calculated. The U.S. incidence was 1.11 cases per 100,000 persons. Most cases occurred among older, white males. However, 173 cases (< 2%) occurred in persons younger than 40. The proportion of women with peritoneal mesothelioma was triple that of men (14.8% vs 5.4%). Of 40 reporting states, 11 had incidence rates significantly higher than the national rate.
