Colonoscopy Screening Intervals Could Be Extended For Some Patients, Researchers Suggestby Marla Milling
The standard advice for average-risk adults (ages 50-66) who have a negative colonoscopy is to have another one in 10 years.
That may be changing.
Researchers at The Maria Sklodowska-Curie National Research Institute of Oncology in Warsaw, Poland believe the currently recommended 10-year screening interval could be safely extended.
The observational study published in the Annals of Internal Medicine says that a single negative high-quality screening colonoscopy is associated with an 84% reduced chance of colorectal cancer (CRC) and a 90% reduction in death for up to 17.4 years.
Study authors say “only high-quality colonoscopy provided a profound and stable reduction in both CRC incidence and mortality throughout follow-up.”
The study analyzed a screening registry of 276,372 people. Of those, more than 110,000 were excluded because they did not have a negative colonoscopy or they had a family history of CRC or other factors.
