circulating tumor DNA

The firm's has expanded its ctDNA sequencing test to cover 17 genes, enough to provide a readout of microsatellite instability for guiding cancer immunotherapy use.

The firm's new RT-PCR assay identifies 20 gene fusion between NTRK1/2/3 and other genes, allowing clinicians to potentially detect rare forms of different cancers.

The firm is moving into a larger facility after its first full year of profitability and planning new hires to support its plans to bring liquid biopsy kits through the FDA.

Plans are in place for a Guardant360-based assay to predict response to AsztraZeneca's Tagrisso and for a blood-based TMB test using the larger GuardantOmni panel.

Research continues to show that it is possible to detect genetic signs of cancer in a blood sample without the need to measure specific oncogenic mutations.

At the conference, researchers presented data from a number of studies using molecular diagnostic tools to better characterize breast cancer recurrence and treatment outcomes.

Qiagen and Foundation Medicine will develop tissue- and plasma-based companion tests to identify best responders to the PI3K inhibitor alpelisib

With a DNA methylation atlas and deconvolution algorithm, researchers are attempting to trace cfDNA back to tissue sources in healthy or ill individuals.

A circulating tumor DNA analysis identified somatic mutations in more than 64 percent of advanced non-small cell lung cancer cases, including some drug targets.

Investigators published an initial report on the method, which they call cfMeDIP-Seq, last week, and are now hoping to move to analysis of samples from longitudinal health studies.
