TCGA is a community resource project and data are made available rapidly after generation for community research use. To act in accord with the Fort Lauderdale principles and support the continued prompt public release of large-scale genomic data prior to publication, researchers who plan to prepare manuscripts containing descriptions of TCGA data that would be of comparable scope to an initial TCGA comprehensive, global analysis publication, and journal editors who receive such manuscripts, are encouraged to coordinate their independent reports with TCGA's publication schedule. Specifically, comparable scope is defined as global genome-wide analysis of TCGA data from more than one platform OR analysis of data from a single platform across more than one tumor type under moratorium. Publication involving such analyses is restricted prior to the TCGA publication moratorium release date as described further below.
TCGA defines a global analysis publication as the first paper authored by The Cancer Genome Atlas Research Network which includes the data from at least 100 cases of a specific tumor type and includes analysis of much of the existing TCGA data on that tumor type at the time. For rare tumor projects a global analysis publication includes data from a majority of the qualified cases and much of the existing data on that tumor type. Specifically, these manuscripts report on the comprehensive, integrated analysis of multiple TCGA datasets available including, but not limited to, copy number variation, gene and miRNA expression, promoter methylation and DNA sequence/mutation analysis. A global analysis publication is also defined as an analysis of data from a single platform across more than one tumor type under moratorium. Prior to a global analysis publication on a specific tumor type, available datasets should be considered pre-publication data subject to the standard principles of scientific etiquette regarding publication of findings using data obtained from other sources.
The TCGA program has established the following policy to clarify freedom of TCGA and non-TCGA users to publish findings using TCGA data. There are no limitations on publications containing analyses using any TCGA data set if the data set meets one of the following three freedom-to-publish criteria:
- A global analysis publication has been published on that tumor type; or
- 18 months after 100 cases of a given tumor type have shipped from BCR to characterization and sequencing centers or 18 months after final sample shipment for rare tumor projects; or
- The author receives specific approval from the TCGA Publication Committee in consultation with appropriate disease-specific analysis group(s).
Specifically, the status of each tumor dataset is available below. If you have questions, do not hesitate to contact firstname.lastname@example.org.

Use of TCGA Data in Publications Prior to Initial TCGA Global Analysis Publication
Researchers are free, and indeed encouraged, to publish results based on TCGA data. These results may include, but would not be limited to, integrating TCGA data with data from other sources, particularly in efforts to study the role of specific genes and genomic changes in the biology of cancer. Researchers also are encouraged to use TCGA data to publish on the development of novel methods to analyze genomic data related to cancer and genotype-phenotype relationships in cancer. This may include the application of these methods to portions of the data, for example, specific cancer subtypes, the role of specific genes or gene sets, or particular aspects of tumor biology.
The National Cancer Institute (NCI) and National Human Genome Research Institute (NHGRI) do not consider the deposition of data from TCGA, like those from other large-scale genomic projects, into its own Data Portal or public databases as the equivalent of publication in a peer-reviewed journal. Therefore, although the data are available to others, the producers consider these data as unpublished and expect that the data will be used in accord with standard scientific etiquette and practices concerning unpublished data.
Specifically, both TCGA and non-TCGA investigators using TCGA data that have not met a freedom-to-publish criterion per TCGA policy are asked to provide the TCGA Publications Committee and appropriate tumor-specific analysis groups with an abstract summarizing the findings and use of TCGA data. Authors will receive feedback on whether the TCGA Research Network requests that the findings be submitted in coordination with our global analysis publication of a specific tumor type or whether the submission can occur independent of a TCGA publication. This assessment may also apply to submission of manuscripts to journal editors. This request can be made via email to firstname.lastname@example.org.
Use of TCGA Data in Publications after Initial TCGA Global Analysis Publication
There are no restrictions on the use of TCGA data to publish work after the initial TCGA global analysis publication. Once the TCGA Research Network has published tumor-specific analyses, no specific permission is needed for other investigators to publish using these data or future data generated on the same tumor type. Specifically, all data on that tumor type are released from any limitations as soon as the global analysis is published. However, researchers are encouraged to coordinate with the TCGA Research Network via email to email@example.com when performing multi-platform analysis in these tumor types to explore opportunities for collaboration.
Use of TCGA Data for Research Purposes other than Publication
There are no restrictions on the use of TCGA data for legitimate research purposes not involving publication or public presentation. For example, researchers may use TCGA data in research grant applications or proposals at anytime, regardless of whether the initial TCGA global analysis has been published.
TCGA Program Attribution in Publications and Presentations
TCGA requests that authors who use data from TCGA acknowledge the TCGA Research Network in their work by properly referencing the TCGA dataset. Inclusion of the Network in the authorship list is not required. However, collaborators seeking to add The Cancer Genome Atlas Research Network to the list of authors should share the manuscript with the TCGA Steering Committee for approval prior to submission. Manuscripts may be submitted to firstname.lastname@example.org for review. Authors are also encouraged to recognize the contribution of the appropriate specimen donors and research groups via the acknowledgements section in their publication. Similarly, the TCGA Program requests that journal editors and reviewers attempt to ascertain if TCGA is cited and if appropriate acknowledgements are made.
