Proof-of-concept Study of Blood Markers of Tumor Dissemination in Patients With Versus Without Intestinal Polyps

Overview

The study authors hypothesize that in patients with intestinal polyps, tumor cells could disseminate and circulating factors could be secreted by the polyp. These two parameters could become biomarkers to refine the follow-up of patients and to establish targeted therapeutic strategies.
