CBTRUS Statistical Report: Primary Brain and Central Nervous System Tumors Diagnosed in the United States in 2005-2009

Abstract

primary brain and CNS tumors in the United States. This report represents a dramatic increase in population coverage (approximately 97% from the initial CBTRUS Reports). The central cancer registries receive populationbased, standardized data from all healthcare data sources primarily through certified tumor registrars. Along with the UDS, there are quality control checks and a system for rating each central registry to further insure that these data are reported as accurately and completely as possible. These individuals and organizations provide the high quality data that are the foundation of the CBTRUS statistical reports and scientific activities.
