EXPOSE Study: Exosomal microRNA Signature for Preoperative Staging in Colon Cancer

This observational study, called EXPOSE, is looking for 400 participants with colon cancer to help develop a new diagnostic test. The goal is to find a way to more accurately identify patients with aggressive colon cancer (pathological stage IIB or higher) before surgery. This information could help doctors decide if neoadjuvant chemotherapy (chemotherapy given before surgery) would be beneficial. Researchers are testing two diagnostic methods: the EXPOSE assay (which uses small RNA sequencing of exosomal microRNAs) and the EXPOSE RT-qPCR panel (which quantifies exosomal microRNAs). The study aims to see if these tests can predict a patient's pathological stage IIB or higher status one year after surgery. You may be eligible if you have confirmed colon cancer, have had or will have surgery, and have available preoperative blood samples and clinical data.
