How frequently should CTC be performed?
There is little long-term data on the optimal frequency at which CTC should be performed. However, according to joint guidelines from the American Cancer Society (ACS), the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology (ACR), CTC should be performed every 5 years, similar to double-contrast barium enema. This is compared to every 10 years for OC among patients with no polyps.
