Detection of Circulating Tumor DNA in Plasma: A Potential Biomarker for Esophageal Adenocarcinoma [1]
Egyud and colleagues evaluated plasma levels of circulating tumor (ct)DNA in patients with esophageal adenocarcinoma, ranging from stage I to stage IV. The quantity of ctDNA and likelihood of ctDNA detection was greater at later stages, suggesting that it may be challenging to use for early-stage diagnosis. However, changes in ctDNA levels were indicative of response to therapy and recurrence, and the authors conclude that they may serve as a dynamic biomarker to monitor a patient’s response to treatment.
