Exosome-based Detection of Molecular Residual Disease in Stage II-III Colorectal Cancer

This study aims to establish an exosome-based liquid biopsy signature to detect molecular residual disease (MRD) in stage II-III colorectal cancer (CRC) patients. Identifying patients with MRD after surgery is crucial for selecting appropriate candidates for adjuvant chemotherapy (ACT), allowing for more personalized treatment approaches and potentially improving patient outcomes.
