Overall Study Goal: To determine brain and CNS tumor incidence and survival patterns among U.S. adolescents and young adults.
Study Data Sources Incidence: All Primary CBTRUS 2000-2004 SEER 2004-2006 Survival: Malignant Primary SEER 1973-2006
Demographic Characteristics • Age Groups: 15-19, 20-24, 25-29, 30-34 • Gender: Males, Females • Race/Ethnic Groups: Hispanics Black, non-Hispanics Other, non-Hispanics White, non-Hispanics
Brain and CNS Tumor Definitions - Behavior Non-Malignant (0, 1) Passed in 2002 - Public Law 107-206 Required collection of benign (0) and uncertain (1) behavior starting with cases diagnosed in January 2004 Malignant (3) Note: Pilocytic astrocytomas are included in malignant category.
Statistical Methods Measures: • Frequencies • Age-specific Rates • Annual Percentage Change • Kaplan-Meier Survival Method for Cohort and Period Analysis • Proportions for 5-year survival All Analyses Performed Using SEER*Stat Version 6.5.1

Summary Point • Brain and CNS tumors among adolescents and young adults are unique in that the patterns of site and histology groupings reflect transitional patterns from those observed for children to older adults.
Summary Point Non-malignant tumors are an important subgroup in these age groups because of their high relative frequency compared with younger age groups.
Summary Point Proportionately, non-malignant pituitary tumors exhibited high representation within these age groups.
Summary Point Brain and CNS tumor incidence rates for Hispanics and Black, non-Hispanics were observed to be lower than their White, non-Hispanic and Other, non-Hispanic counterparts.
Summary Point • 5-year period relative survival rates were observed to be greater than 60% in these age groups indicating improvements and progress in treatment outcomes.
