The therapeutic management of malignant colorectal polyp with endoscopic resection is mainly based on specific histopathological criteria. The quality of these criteria is strongly linked to the management of the endoscopic specimen. The French Pathology Society drafted a standardized pathological report with
guidelines for the macroscopic management of the endoscopic specimen and explanatory notes for each histopathological criteria. These
guidelines are based on the TNM AJCC/UICC classification, 8th edition and the WHO 2010 classification of colorectal tumors, the recommendations of the French Society of Digestive Endoscopy, the synthesis of the literature and on international
consensus for prognostic criteria. The pathological report of a malignant colorectal polyp must clearly mention: the histological type and the size of the polyp, the pT stage and the following five prognostic criteria: the value of the resection margins, the level of tumor invasion into the submucosa, the grade of the tumor, the absence or presence of vascular emboli and of tumor budding.
