Application of a Tissue-Free Epigenomic Assay to Improve MRD Detection in Previously Treated CRC - Episode 3

COSMOS-CRC-01: Clinicopathologic Correlation of ctDNA With RFS

October 14, 2024

Yoshiaki Nakamura, MD, PhD, discusses how the COSMOS-CRC-01 study demonstrated statistically significant recurrence-free intervals across various postoperative and adjuvant chemotherapy time points, highlighting the prognostic value of serial, tissue-free ctDNA assays for real-time detection of MRD vs single postchemotherapy assessments.

1. Please summarize the statistically significant recurrence-free intervals across the postoperative, post-ACT, and paired pre- and post-ACT analyses in the COSMOS-CRC-01 study.

2. Please address the prognostic value of serial, tissue-free, epigenomic ctDNA assays in detecting MRD in real time vs a single postchemotherapy time point.
