  • We conclude that in early colorectal cancer arising in pedunculated polyps (0-Ip), mucosal endoscopic resection would be indicated as only treatment in Haggitt levels 1, 2 and 3, tumors smaller than 2 cm, well- or moderately differentiated, without vascular or lymphatic affection, with submucosal infiltration lower than 1 µm from the muscularis mucosae and maximal submucosal width lower than 4 µm, and undergoing en bloc resection. (isciii.es)
  • Those polyps with a size bigger than 3 cm, affecting more than one third of circumference or two colonic haustras, or with flat or depressed morphology are more difficult to be resected with the conventional endoscopic polypectomy, thus with the new endoscopic approaches, such as endoscopic mucosal resection, the number of resected polyps has increased, avoiding the surgical act in many cases (10). (isciii.es)
  • In addition, six out of eight affected subjects who have positive germline mutation have confirmed neoplastic colonic polyps, indicating that colorectal neoplasia is an associated feature of BHD in some families. (bmj.com)

  • We posit that gCD and propolis induce the release of neoplasm-associated biomarkers in systemic circulation (e.g., metabolites, neoplastic, apoptotic, and immune response proteins), and these markers could be used to detect early stage intestinal neoplasms. (jcancer.org)
  • METHODS: In 210 female C57bl mice, colonic tumours were initially induced with the methylating carcinogen 1,2-dimethylhydrazine (DMH) and mice were then treated with GLP-2. (ku.dk)
