eLife Assessment
This study presents an important finding that has identified 27 differentially methylated regions as a signature for non-invasive early cancer detection and predicting prognosis for colorectal cancer. The findings demonstrate promising clinical potential, particularly for improving cancer screening and patient monitoring. In general, the evidence supporting the claims of the authors is solid. A larger sample size will be key to further improving this work in the future. The work will be of interest to researchers interested in cancer diagnosis or colorectal cancer monitoring.
