NCT06314971

Brief Summary

Tumor recurrence significantly affects survival rates following the local resection of submucosal colorectal cancers (T1 CRC). Despite this, there are currently no reliable biomarkers established to predict recurrence in T1 CRC. This study seeks to improve the prediction of recurrence-free survival in individuals who have survived T1 CRC.

Study Population

Two cohorts of patients with T1 colorectal cancer

You may qualify if:
