Criteria: * Documentation of Disease * Patients must have one malignant polyp, pathologically confirmed within 90 days of enrollment. Patients with multiple malignant polyps are not eligible. * Definition of Disease Colorectal carcinoma (CRC) develops within serrated or adenomatous polyps.

These lesions are classified as pT1 in the TNM classification system (24) Prior Treatment Endoscopic resection of the polypoid lesion-malignant polyp with simple snare polypectomy, conventional endoscopic mucosal resection (EMR), or endoscopic submucosal dissection (ESD) (25). * Age ≥ 18 Exclusion Criteria: A patient will be considered inelligibe for this study if any of the following conditions apply: * Synchronous malignancy * Hereditary cancer syndromes * History of Inflammatory bowel disease
