BACKGROUND: Because World Health Organization (WHO) grades II and @entity1653 are relatively uncommon, there is limited literature on the descriptive epidemiology of these @entity5 , and the existing literature predates the 2000 WHO classification revisions. Our purpose was to provide a modern, population-based study of the descriptive epidemiology of @entity347 in the United States. METHODS: The Central @entity1313 Registry of the United States (CBTRUS) was queried for @entity1653 categorized by WHO grade for the 2004--2010 study period. Age-adjusted incidence (95% confidence interval in parentheses) per 100,000 population was calculated by age, sex, race, and ethnicity. @entity1987 ( @entity1987 ) was calculated using Joinpoint. RESULTS: From 2004 to 2010, the incidence of WHO II @entity1653 increased from 0.28 (95% CI, 0.27--0.29) to 0.30 (95% CI, 0.28-0.32), representing an @entity1987 of 3.6% (95%CI, 0.8%-6.5%). Conversely, from 2000-2010, the incidence of @entity347 decreased from 0.13 (95% CI, 0.11-0.14) to 0.06 (95%CI, 0.06-0.07), representing an @entity1987 of -5.4% (95% CI, -6.8% to -4.0%). From 2004 to 2010, the overall proportion of WHO I, II, and III @entity1653 was 94.6%, 4.2%, and 1.2%, respectively. For @entity347 , females in the 35-64 year age group had a higher incidence than males in the same age group, whereas males in the >=  75 year age group >=  had a higher incidence. Black and Asian Pacific Islander races were both associated with the highest incidence of @entity347 . Hispanic ethnicity was not associated with any difference in incidence. CONCLUSION: This study presents the most comprehensive evaluation of the modern descriptive epidemiology of @entity347 . Temporal trends likely reflect the 2000 WHO histological criteria revisions.
