The Cooperative Italian FLIN Study Group: prevalence and clinico-pathological features of colorectal laterally spreading tumors

Abstract

LSTs represent approximately 5% of all precancerous colorectal lesions in the Italian population and are prevalent in the proximal colon. These lesions are no more likely to harbor advanced histology than similar-sized polypoid lesions. Large nodularity or depressed surface are risk factors for advanced histology.
