To Realize the Potential of Liquid Biopsies, Focus on Higher Quality Research and Clinical Data Sets

Posted by Dan Brudzewsky on Oct 15, 2018 9:30:00 AM

Liquid biopsy requires better standardization to realize all the new possibilities for studying metastasis, heterogenicity, treatment efficacy, and disease recurrence. Furthermore, it is critical for clinicians to have confidence in liquid biopsy data to diagnose and treat patients. This is only achievable when consistent and high-quality data is generated at research and all clinical centers. The Liquid Biopsies course at EMBL Advanced Training Centre provides a unique practical training in best practices and pitfalls on the complete liquid biopsy workflow, from sample preparation to data analysis. The course is targeted for clinical laboratory and research scientists interested in learning all aspects of liquid biopsy testing.

How A New Generation of ctDNA Reference Standards Are Enabling the Promise of Precision Medicine

Posted by Omo Clement, Ph.D. on Jun 14, 2018 10:00:00 AM

An important goal in cancer disease management is early detection. When detected early, disease progression can be significantly mitigated with a plethora of options (targeted therapy, chemotherapy, surgery, etc.) available to medical practitioners, to afford progression free survival and a higher quality of life. A great promise of liquid biopsies is the possibility of early detection of cancer long before clear evidence of lesions and tumor growth observable by imaging or other techniques.1 As proxy for solid tissue biopsies, plasma-based liquid biopsy application is rapidly gaining traction in cancer disease diagnosis, progression, monitoring, and in predicting resistance to treatment options.2

Accelerating Liquid Biopsy Assay Development

Session Summary from Next Generation Dx Summit 2017

Posted by Sam Blier on Sep 8, 2017 11:15:00 AM

At the 2017 Next Generation Dx Summit in Washington, DC, our CSO, Russell Garlick, PhD, presented a workshop on accelerating liquid biopsy assay development. He has worked closely with a variety of groups in the liquid biopsy space that are developing and validating circulating tumor DNA (ctDNA) assays. He highlighted some common challenges facing the field, and explained how SeraCare has been using these collaborations to develop QC tools specifically for ensuring the robustness of these cutting-edge tests.

How Many Target Copies Are Present in Your Plasma DNA Sample?

A 0.1% measurement requires a reasonable amount of input material

Posted by Dale Yuzuki on Jun 15, 2017 1:30:00 PM

The field of circulating tumor DNA analysis (ctDNA, also sometimes called in a larger context “liquid biopsy”) holds great promise for monitoring response to cancer treatment, assisting therapeutic choice, monitoring recurrence, and for pre-cancer screening. As such there is a great amount of assay development and ongoing clinical trials; at ClinicalTrials.gov searching for the term "Circulating DNA" you can find over 180 open clinical trials for a wide range of tumor types and interventions.

What lessons for liquid biopsy have been learned from fetal aneuploidy testing?

Posted by Russell Garlick on Sep 30, 2016 1:06:00 PM

Non-invasive prenatal screening (NIPS) is currently offered in over 80 countries, covering over 80 million annual births, with an estimated volume of over one million screening tests performed annually. First offered in 2011, there has been rapid adoption of these genomic tests in the marketplace.
