Molecular Testing

    Excerpt from GenomeWeb:

    “Researchers from Genentech, Foundation Medicine, UC Davis, and other medical centers, have published a report on the development and early validation of Foundation’s planned blood-based tumor mutational burden test.

    “Appearing today in Nature Medicine, the study describes the development of the test and its characteristics, and its retrospective validation in two cohorts. Investigators demonstrated, by applying the assay to samples from two clinical trials, that blood-based TMB (bTMB) could reproducibly identify lung cancer patients who respond to immunotherapy treatment with Roche/Genentech’s atezolizumab (Tecentriq).”

    Excerpt:

    “U.S. regulators have approved a first-of-a-kind test that looks for mutations in hundreds of cancer genes at once, giving a more complete picture of what’s driving a patient’s tumor and aiding efforts to match treatments to those flaws.

    “The U.S. Food and Drug Administration approved Foundation Medicine’s test for patients with advanced or widely spread cancers, and the Centers for Medicare and Medicaid Services proposed covering it.

    “The dual decisions, announced late Thursday, will make tumor-gene profiling available to far more cancer patients than the few who get it now and will lead more insurers to cover it.”

    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 and concerns described in the original post below have been addressed and largely resolved by refining the technology. The latest proof of this is… Read more »
