{{Short description, Cancer biomarker discovery project
The Early Detection Research Network (EDRN) is a collaboration led by the
National Cancer Institute
The National Cancer Institute (NCI) coordinates the United States National Cancer Program and is part of the National Institutes of Health (NIH), which is one of eleven agencies that are part of the U.S. Department of Health and Human Services. ...
(NCI) focused on the discovery of cancer biomarkers. The effort, started in 2000, includes both principal investigators and associate members from leading research institutions across the United States.
The objectives of EDRN include:
* Developing and testing promising biomarkers and technologies to obtain preliminary information to guide further testing;
* Evaluating promising, analytically proven
biomarker
In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues to examine normal biological processes, ...
s and technologies, such as measures of accuracy, sensitivity, specificity and, when possible, as potential predictors of outcomes or surrogate endpoints for
clinical trial
Clinical trials are prospective biomedical or behavioral research studies on human subject research, human participants designed to answer specific questions about biomedical or behavioral interventions, including new treatments (such as novel v ...

* Analyzing biomarkers and their expression patterns to serve as background for large, definitive validation studies;
* Collaborating with academic and industrial leaders to develop high-throughput, sensitive

To disseminate (from Latin, lat. ''disseminare'' "scattering seeds"), in the field of communication, is to broadcast a message to the public without direct feedback from the audience.

Dissemination takes on the theory of the traditional ...
of information to ensure progress and avoid fragmentation of effort.
Since 2000, EDRN has established a national infrastructure to support validation of cancer biomarkers through innovative research and technology approaches. EDRN supports validation of some of the most promising proteomic and genomic markers evaluating their results for continued research. The biomarkers must be reliable and repeatable in testing; highly sensitive and specific; quantitative; readily obtained by non-invasive methods; part of the causal pathway for disease; capable of being modulated by the

The EDRN is organized to perform research around specific organ sites. Research teams within and outside EDRN are established to develop protocols of study around each of these organ sites. Within the EDRN, collaborations are established so researchers involved in specific organs can work together and study results. These organ groups include
breast
The breasts are two prominences located on the upper ventral region of the torso among humans and other primates. Both sexes develop breasts from the same embryology, embryological tissues. The relative size and development of the breasts is ...

The EDRN also has been a pioneer in the development of a national informatics infrastructure to support cancer biomarker research. By leveraging technology development for planetary science at NASA's Jet Propulsion Laboratory, the EDRN has been able to develop and deploy an infrastructure to support

Data sharing is the practice of making data used for scholarly research available to other investigators. Many funding agencies, institutions, and publication venues have policies regarding data sharing because transparency and openness are consid ...
