Endoscopic resection of high risk colorectal carcinoma does not negatively affect patient outcomes

WASHINGTON — Patient outcomes are not negatively affected by the endoscopic resection of high-risk colorectal carcinomas followed by surgery, according to study findings presented at DDW 2015.There are no histologic risk factors for lymph node metastases at baseline for about 25% of T1 colorectal carcinomas. These can be treated by endoscopic resection only, however, during colonoscopy, it is difficult to tell the difference between low-risk and high-risk invasive cancers, according to Anouk Overwater, MD, a gastroenterologist in the department of gastroenterology and hepatology at the University Medical Center Utrecht, Netherlands.
