This year's report (2005-2006) will be the last report in which data have come voluntarily from central state cancer registries who have been our collaborators over the last years. On June 7, 2005 we held our last Collaborators Working Luncheon during the North American Association of Central Cancer Registries Annual Meeting where I had the opportunity to thank the individuals who have steadfastly supported us in word and in deed. Fortunately, we will continue to work with them, and we will continue to use their data, although collection will be different. Progress has been made! Starting in 2007, we hope to be reporting primary brain tumor data through the National Program of Cancer Registries (NPCR). We are excited to know that data collected in 2004, the year Public Law 107-260 mandated NPCR to collect data on non-malignant (benign) brain tumors, will provide us with the opportunity to analyze data on all primary brain tumors from most of the United States. We have worked with NPCR in the preparation of this 2005-2006 report. Our commitment to provide high quality incidence data on all primary brain tumors in the United States will only be enhanced by this future relationship. During this interim period the CBTRUS will continue to work to improve the data collection practices for primary brain tumors, to foster the epidemiology of brain tumors through the Brain Tumor Epidemiology Consortium, and to contribute to the literature on the descriptive epidemiology of brain tumors. On behalf of the Board of Directors and Advisors, I would like to thank our collaborating registries for providing data for this statistical report, our sponsors for providing financial support, and to all those who support our mission. Carol Kruchko President & Administrator, CBTRUS
