Postoperative circulating tumor DNA could guide CRC adjuvant treatment

The large, ongoing CIRCULATE-Japan trial is investigating the role of circulating tumor DNA (ctDNA)-based molecular residual disease testing in patients with resectable colorectal cancer after radical surgery. An interim analysis of GALAXY, a prospective, observational arm of CIRCULATE-Japan, establishes ctDNA as a prognostic and predictive biomarker.
