    The U.S. Food and Drug Administration (FDA) has approved a liquid biopsy test (a type of biopsy that uses a blood draw instead of surgery) for detecting whether patients have EGFR mutations in their metastatic lung tumors, which could help guide treatment options.

    Article from Clinical OMICs curated by Editor in Chief George Lundberg, MD, who notes: 

    Researchers have recently demonstrated a noninvasive way to diagnose and classify brain tumors using a blood test. This promising “liquid biopsy” method detects cell-free tumor DNA in the blood and analyzes its chemical features—specifically, its “methylation patterns”—with high sensitivity and accuracy. Such a test could help guide treatment decisions.

    Excerpt:

    “New research by investigators at the University of California, San Francisco and the Children’s National Health System, has provided early evidence that liquid biopsy testing could help doctors monitor how well treatments are working in kids with diffuse midline gliomas.

    “Brain cancers present a challenge for longitudinal monitoring, because obtaining repeat biopsy samples is dangerous and difficult. But liquid biopsy techniques have now opened the possibility of tracking these and other tumors over time based on analysis of tumor genetic material that is shed into the blood or other body fluids.”

    Excerpt:

    “New data this week has added evidence for the value of blood-based cancer testing in non-small cell lung cancer, demonstrating in a cohort of about 300 that comprehensive liquid biopsy — in this case Guardant Health’s Guardant360 test — can help identify targeted mutations in more patients than tissue sequencing.

    “The study also found that patients treated on the basis of blood-based test results respond to treatment similarly to those treated based on tissue test results.”

    Testing for Tumor Mutations: Liquid Biopsy Versus Traditional Biopsy

    Emma Shtivelman, PhD

    Update as of August 27, 2020: A lot has changed in the three-and-a-half years since this blog post was written. Liquid biopsies are by now widely recognized and used as a valuable diagnostic and monitoring tool. Many of the reservations… Read more »
