Driven by input from the scientific community, the Cancer Imaging Program (CIP) stands at the crossroad of two powerful scientific requisites: the need for cross-disciplinary research and the increase of inter-institutional data sharing. The Cancer Imaging Archive (TCIA) is building a research community focused on connecting cancer phenotypes to genotypes by providing clinical images matched to subjects from The Cancer Genome Atlas (TCGA). |
TCGA began in 2006 as a three-year pilot jointly sponsored by the National Cancer Institute (NCI) and National Human Genome Research Institute (NHGRI). The TCGA pilot project (focused initially on glioblastoma, ovary, and lung cancers) confirmed that an atlas of genomic changes could be constructed for specific cancer types. It also showed that national networks of research and technology teams working on related projects could pool their efforts, create an economy of scale, and develop an infrastructure for making the data publicly accessible. Freely available data enables researchers across the world to make and validate important discoveries. The success of that pilot encouraged the National Institutes of Health (NIH) to invest in TCGA’s efforts to collect and characterize more than 20 additional tumor types and make findings freely accessible for researchers to download via TCGA Data Portal.
As an opportunity to leverage this wealth of new biomedical knowledge, CIP used its agreements with TCGA Tissue Site Source institutions to collect clinical diagnostic images for TCIA that match genomically analyzed tissue cases in the 20-plus cancer types that TCGA has characterized.
Frederick National Lab Research Efforts
Imaging Source Site (ISS) Groups are being populated and were organized by the Cancer Imaging Informatics Lab within the Frederick National Laboratory for Cancer Research. The groups were governed by participants from institutions that have which provided imaging data to the archive for a given each TCGA cancer type. Modeled after the TCGA genomic analysis groups, ISS groups are given the opportunity were given a one year embargo window after 100 cases were accrued to publish a marker paper for a given cancer type per the guidelines in the table abovetype. This opportunity will generate increased participation in building these multi-institutional data sets as they become an open community resource. Current ISS groups includeincreased incentive among source sites to contribute their patients' images, which would ultimately become a public resource to enable radiogenomic research. The ISS groups included:
