INVESTIGATOR PERSPECTIVES Application of a Tissue-Free Epigenomic Assay to Improve MRD Detection in Previously Treated CRC

Yoshiaki Nakamura, MD, PhD, discusses how the use of tissue-free circulating tumor DNA (ctDNA) analysis for detecting minimal residual disease (MRD) can enhance the prediction of recurrence in stage II to III colorectal cancer (CRC), particularly when tumor specimens are limited.

Yoshiaki Nakamura, MD, PhD, discusses how the COSMOS-CRC-01 study was designed to evaluate the efficacy of ctDNA analysis for MRD detection, outlining the rationale for patient enrollment, the timing of plasma sample collection, and the implications for monitoring disease post surgery and during adjuvant chemotherapy.
