The National Cancer Institute (NCI) Center for Biomedical Informatics and Information Technology (CBIIT) is planning to retire the caIntegrator data portal on or after January 30, 2015. Much of the study data currently hosted in the NCI instance of caIntegrator is also available in other data portals, including the Cancer Genome Atlas TCGA data portal. Those data that are not available elsewhere will be migrated to the Georgetown Database of Cancer G-DOC 
. Upon retirement, the caIntegrator URL will be redirected to a web page that will direct visitors to the current location of these data, to make the transition as smooth and easy as possible.
Please contact NCI CBIIT Application Support if you have any questions or concerns.
