Peripheral Blood Monocytes as Predictive Marker for Colorectal Cancer Diagnosis: A Comparative Study of a Stool Based Versus Blood Based Screening Test

In this prospective study, the main goal is to evaluate the strength of Monomark -a monocyte-based transcriptomic test combined to a mathematical model- in patients with a positive FIT test. Therefore, in parallel to the routine FIT screening, blood samples will be harvested and the monocyte genetic profile will be determined. This fundamental study, will disclose the diagnostic power of a biomarker panel ("MonoMark") head to head with the well-established FIT diagnostic test, a core prerequisite for the routine use of this test as an alternative and more reliable CRC screening tool.
