Magnus Løberg and Michael Bretthauer from the Department of Transplantation Medicine at Oslo University Hospital are first and last author respectively on an article recently published in New Eng J Med (journal impact factor 54.42), entitled "Long-Term Colorectal-Cancer Mortality after Adenoma Removal".
Taking advantage of nationwide data in the Cancer Registry of Norway on patients who have had colorectal adenomas removed, they have evaluated colorectal-cancer mortality in a large, population-based cohort with virtually complete follow-up for death from colorectal cancer.
The findings are commented in an editorial in NEJM.

Their finding that the removal of low-risk adenomas reduces the risk of death from colorectal cancer over a period of 8 years to a level below the risk in the general population is consistent with the hypothesis that surveillance every 5 years after removal of low-risk adenomas may confer little benefit over less intensive surveillance strategies. Furthermore, complications associated with colonoscopy are not trivial and might offset the benefit of surveillance.
