Liquid Biopsy Workshop


A HUPO Workshop on Liquid Biopsy:

Principles, Process and Practices

Classroom E2.18, O’Brien Centre for Science, University College Dublin

In the era of personalized medicine, it is desirable to have noninvasive or minimally invasive methods to determine and follow longitudinally the molecular composition of a patient’s progress/health, which will help gain a broader molecular understanding of the disease. One such approach is through liquid biopsies that can be used to characterize the specific disease and monitor proteomic changes over time using repeat sampling of biofluids. While most of the research on liquid biopsies uses blood derivatives, other biofluids that can be used include urine, sputum, saliva, tears and nipple aspirate fluid. Liquid biopsies have the potential to help clinicians screen for disease, stratify patients to the best treatment, monitor treatment response and development of resistance. Liquid biopsies also offer an opportunity to detect diseases at the earliest stage and monitor recurrence in cases where biopsy is difficult, such as brain cancer. The race to capitalize on the approach has ignored the contribution of proteomics that is poised to benefit more broadly than genomics. The workshop will discuss the principles, process and practice of liquid biopsy in general and the role of proteomics in particular. Attendees will learn both existing and emerging technologies that can be beneficial in the pursuit of liquid biopsy in the point of care applications.
