A blood test to detect lung cancer inches toward the clinic

Uptake of recommended low-dose CT for lung cancer screening has been dismal. Blood-based assays are an attractive alternative being explored by the Circulating Cell–Free Genome Atlas (CCGA) project. Interim results of a CCGA study of 561 individuals without cancer and 118 patients with lung cancers of all stages have found that a trio of assays searching for molecular signatures in plasma cell-free DNA achieved roughly 50% sensitivity for detection of early-stage (stage I-IIIA) lung cancers and 91% sensitivity for detection of late-stage (stage IIIB-IV) lung cancers.

In this video interview from the annual meeting of the American Society of Clinical Oncology, lead study author Geoffrey R. Oxnard, MD, of the Dana-Farber Cancer Institute, Boston, discusses the science behind these assays, how they may fill an unmet medical need, and ongoing work to bring them into the clinic.
