The risk of advanced histology in small-sized colonic polyps:  are non-invasive colonic imaging modalities good enough?
A non-negligible fraction of small polyps harbor advanced histology. This finding suggests that expectant follow-up by non-invasive colonic imaging modalities for small polyps or not reporting them may put more than 5% of patients at risk of dysplasia progression.
POLR2F and PRNP exhibited elevated levels in carcinomas compared to normal tissue samples suggesting a possible role for these molecules in colorectal cancer. The association of the three molecules with survival or disease prognosis warrants further investigation.
