circulating tumor DNA

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.

Investigators showed that sequencing cell-free DNA could detect microsatellite instability, structural rearrangements, and clonal hematopoiesis in patients with metastatic disease.

Following recent publications and anticipating the readout from its NILE study next year, the company plans to make the case that its liquid biopsy approach performs as well as tissue tests.

The company reported revenues of $21.7 million compared to $11.1 million in the year-ago quarter, overshooting analysts' expectations of $17.5 million.

Investigators shared data at an oncology meeting last week, showing that the test has high sensitivity and specificity in a blinded case-control cohort that included early-stage tumors.
