‘Modest’ benefit of screening colonoscopy in early 70s

medwireNews: Screening colonoscopies could be useful for preventing colorectal cancer (CRC) in individuals aged 70–74 years, although the benefit of routine screening is less clear for those between 75 and 79 years of age.

Among 46,872 Medicare beneficiaries aged 70–74 years who underwent a screening colonoscopy, the 8-year risk of CRC was 2.19%, compared with 2.62% for their 1,762,816 counterparts who did not have the procedure. This gave a significant risk difference of –0.42%, which the authors describe as a “modest” reduction.

For individuals aged between 75 and 79 years, the 8-year CRC risk was 2.84% and 2.97% for those who did and did not undergo a screening colonoscopy, respectively, equating to a nonsignificant risk difference of –0.14%.

“Our findings are consistent with the [US Preventive Services Task Force] recommendations for routine screening through age 75, followed by individualized decisions afterward”, write Xabier García-Albéniz (Harvard TH Chan School of Public Health, Boston, Massachusetts, USA) and co-authors in the Annals of Internal Medicine.
