esophageal cancer

Investigators reported on how ctDNA, measured using Natera's patient-specific Signatera assays, corresponded to a patient's disease progression and other biomarkers.

The diagnostic can now be used to identify patients with esophageal squamous cell carcinoma who may benefit from first-line treatment with Keytruda.

The test relies on a signature that Almac developed for stratifying breast cancer patients, but which, as the researchers showed, can be used in other cancers as well.
