Abstract
Background: It has been postulated that the occurrence of invasive carcinoma in a colon adenoma can be predicted by estimating the size of the resected polyp. Recently, significant intra- and inter-observer differences in size were found when 22 pathologists estimated the size of 12 polyp phantoms. In this work, the size of a large cohort of endoscopically-resected colon polyps was assessed with a novel method. Patients and methods: Three pathologists measured photocopies of 148 resected polyps (adenomas at histology) in two independent trials. Results: The size recorded by the three participants was congruent in only 50% of the measurements in trial 1, and in 62% in trial 2. A significant difference in size assessment was found between the three investigators (p
