Perioperative circulating tumor DNA as a potential prognostic marker for operable stage I to IIIA non–small cell lung cancer

Abstract

The utility of serial circulating tumor DNA (ctDNA) monitoring for predicting disease recurrence and survival for early-stage non-small cell lung cancer (NSCLC) has not been well characterized. The detection of ctDNA before and after surgery is associated with the identification of a high risk of disease recurrence and long-term patient outcomes for resectable NSCLC. Perioperative ctDNA analyses identify disease recurrence earlier than routine radiologic imaging. ctDNA analyses can detect minimal residual disease for resectable NSCLC and thus can facilitate early intervention.
