Fliss-Isakov N, et al. - This case-control study examined the connection between lifetime smoking habits and colorectal polyps of different classifications by analyzing data from 828 consecutive subjects aged 40 to 70 years, undergoing screening or diagnostic colonoscopy. Researchers found that current-smoking had a stronger connection to increased odds for distal vs proximal polyps and with serrated-polyps vs adenomas. Findings suggested an association of colorectal polyps with smoking duration, which is independent of other potential confounders, smoking intensity, and cessation.
