Summary

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.

Detailed description

The current standard for treating stage II-III colorectal cancer involves surgical resection, often followed by adjuvant chemotherapy (ACT) for high-risk patients. However, identifying patients who would benefit most from ACT remains challenging. Molecular residual disease (MRD) in these patients is a critical factor in determining the likelihood of recurrence. This study aims to develop an exosome-based liquid biopsy assay using circulating exosomal microRNAs (exo-miRNAs) to predict the presence of MRD in postoperative patients. By analyzing exo-miRNAs from blood samples collected after surgery, the goal is to identify high-risk patients who may benefit from ACT while sparing low-risk patients from unnecessary treatment. A risk-stratification model, termed the exosome-based molecular residual disease prediction for adjuvant chemotherapy induction (EMRATI) score, will be developed to improve ACT decision-making and enhance clinical outcomes for stage II-III CRC patients.
