Summary
The Cancer Genome Atlas (TCGA) is a comprehensive, collaborative effort led by the National Institutes of Health (NIH) to map the genomic changes that occur in major types and subtypes of cancer. Researchers across the nation are using various genome analysis technologies, including high-throughput DNA sequencing, to carry out this effort.
A pilot project initiated in 2006 established the scientific infrastructure and demonstrated the "proof of concept" needed to mount a large-scale cancer genome mapping project. Based on this success, TCGA announced in September 2009 that it will map the genomes of at least 20 cancers over the next five years.
TCGA makes its data swiftly available to the worldwide research community for use in developing better ways of diagnosing, treating and preventing cancer.

Funding
Funding Institutions: National Cancer Institute (NCI) and National Human Genome Research Institute (NHGRI), both part of NIH.
Funding: $175 million in American Recovery and Reinvestment Act funds, plus $50 million each in appropriated funds from NCI and NHGRI, over two years. Funding for the remaining three years has not yet been finalized.
Pilot Funding: The pilot effort was funded by $50 million each from NCI and NHGRI for three years.
Cancers
Types of Cancer: TCGA is currently in the process of selecting the 20 cancers to be mapped over the next five years. The pilot effort focused on brain (glioblastoma), lung (squamous carcinoma) and ovarian (serous cystadenocarcinoma).
Number of Samples per Cancer: Up to 500 samples of both tumor and matched normal tissues.

Data Access
All data generated by the TCGA research network are made rapidly available to the research community through the TCGA Data Portal.
There are two tiers of data:
- Open Access — Data that cannot be aggregated to generate a dataset unique to an individual. User certification is not required for accessing such data.
- Controlled Access — Clinical data and other individually unique information. This tier of data requires user certification for access.
To reach the TCGA Data Portal and to learn more about its access policies, go to http://cancergenome.nih.gov/dataportal.
