Should I get a colonoscopy?What about the recent article that was published? This is a much more appropriate title to the recently published New England Journal article since the primary intervention being studied was being randomized to get a letter recommending a colonoscopy, or not, not actually getting a colonoscopy itself. The study shows that letters alone won’t prevent colon cancer or death from colon cancer, which isn’t all that surprising!
Notable problems/limitations of this study from the opinion of a gastroenterologist:
1) Only a little over 40% of people who were selected to get a colonoscopy got one. Hard to show a benefit when the study group doesn’t do what is being studied.
2) In US, follow up surveillance after polyps are removed is more frequent. We know that long term surveillance is needed to further minimize risks of colon cancer or death
3) This study is not applicable/generalizable to the US general population as those countries enrolled (Sweden, Norway, Netherlands and Poland) have a predominately white population and a much overall lower rate of colon cancer.
Don’t be fooled, folks. Colonoscopies reduce the risk of colon cancer and your chances from dying due to colon cancer by up to 50%. I will continue to strongly recommend colonoscopy as the best test to both detect and prevent colon cancer for all of my patients.
