Eligibility Criteria:
Inclusion Criteria:~* Aged 18 or above.~* Endoscopically removed colorectal lesion with the following pathological characteristics:~  * A moderately-to-well differentiated adenocarcinoma.~ * If possible to judge: distance between adenocarcinoma and vertical or lateral resection margin is less than 1 mm.~ * In case of piecemeal resection: unjudgeable radicality (mostly due to loss of orientation and multiple fragments).~ * Absence of / unjudgeable lymphatic / vascular invasion.~ * No or only grade I tumor budding.~* No suspicion of dissemination on the following investigations: serum carcino-embryonic antigen, a computer tomographic (CT) scan of the abdomen and a chest X-ray; in case of a rectal tumor (less than 15 cm from the anal verge): an additional magnetic resonance imaging of the rectum.~* Operation is advised in agreement with the Dutch Guideline on Colorectal cancer, planned and agreed on by the patient.~* Written informed consent is obtained.~Exclusion Criteria:~* Pathology shows one or more of the following characteristics:~  * A radical en-bloc resection with a free vertical and lateral margin of ≧ 1 mm.~ * A poorly differentiated or signet-cell containing adenocarcinoma.~ * Lymphatic or vascular invasion (if this feature is unjudgeable due to piecemeal resection, no exclusion is done).~ * Tumor budding grade II-III.~* Suspicion of dissemination on investigations as mentioned in the inclusion criteria.~* Patients already receiving anti-tumor treatment for another tumor or a synchronic colorectal cancer.~* Patients in whom a second-look endoscopy would require major and unacceptable effort and / or resources, for instance clinical admission for bowel preparation, long travel, general anesthesia, extremely difficult to reach polypectomy site. Such at the decision of the patient and / or treating physician.~* Patient is planned for trans-anal surgery.~* Patient is not planned for surgery.~* Patient is pregnant.~* Patient does not provide written informed consent or is unable to provide such.
