Widespread recurrence of pt1 cancer three years and three months after endoscopic mucosal resection
Most authors consider Endoscopic Mucosal Resection (EMR) a safe and effective procedure to treat sessile and pedunculated intramucosal colonic cancers (Tis), as very few cases of local or distant (lymph nodes, liver, lung) metastases have been reported. EMR can be effective also in T1 cancers, which infiltrates submucosa and are associated to an overall 10% rate of lymph nodes metastases, with a rate increasing parallel to their distal site.
