Biorepository & Patient Research Registries

Amazing advances have been made in molecular and cellular biology over the past decade as health care has tranistioned into an exciting era of “precision” medicine, dramatically changing our understanding of factors that mediate gastrointestinal health and disease. Also known as precision medicine, the care of patients has been increasingly guided by the molecular characterization of their diseases, which has allowed care providers to more accurately and comprehensively diagnose GI illnesses earlier, determine prognoses sooner, then predict the risk of disease and response to therapy. While many diseases appear the same clinically, they are very different at the molecular level, and these molecular features will more accurately predict how well the disease responds to specific therapies. This changes how we treat patients and allows us to identify treatments that are likely to be most successful.

Accelerating Precision Medicine

Our ability to translate dramatic advances in our understanding of the molecular pathology of digestive diseases into clinical care has been slowed or blocked by a lack of high-quality, clinically annotated patient samples. To address this deficit in critical research knowledge, the Division and Dr. William Grady, Professor of Medicine at UW and Member of the Fred Hutchinson Cancer Research Center, has established the Gastrointestinal Biorepository and Patient Research Registries.

The Biorepository and Registries form a valuable research resource to a core that is actively collecting tissue samples and health information from prospectively consented patients, who have agreed to allow access to their health data and to donate biosamples for the sake of advancing science and ultimately improving our ability to care for patients. Collected biospecimens are processed using strict, state-of-the-art protocols that ensure their long term viability and future utility in discovery science.

Advancing Cutting Edge Studies of Gastrointestinal Disease & Health

Because the biospecimens reveal information about both the biology of the patient and the disease, it is critical to know as much as possible about our patients and their specific diseases. Well annotated specimens --the who, what, when, and where of each specific specimen—are a unique and essential aspect the of the Registry that makes it extremely valuable for translational research. Because it takes many years to collect enough samples that have a particular characteristic, it is often not possible to do such research without a biorepository as it would take 5-10 years to collect enough samples to even begin a study. By having an existing biorepository, research is accelerated by 5-10 years. More importantly, research that could not be done before biorepositories existed can now take place. This type of resource is often critical for getting NIH grant support in an era of hyper-competition for funding.

The Registry serves as a bridge between the collected biosamples and each patient's health data. The well-annotated samples in the UW biorepository have in-depth and highly detailed demographics, precise and meticulous clinical notations, exhaustive treatment history, and accurately recorded disease information. This data is critical for being able to do translational research that connects studies done in the laboratory with patients and their illnesses. Translational research is what leads to new ways of treating patients.
