MRI imaging appears to hold good value in monitoring patients who have been originally treated (i.e. radiation, chemo) for more localized colorectal cancer (i.e. stage II, III) and who have not received surgery but rather a watch and wait approach (i.e. active surveillance). Those patients who had the better responses (i.e. complete response) to the initial treatment had the better 5 year disease-free survival. It is good to see how MRI used in this area can be predictive of survival, rise of cancer recurrence, and the ability to keep or preserve the bowel. Some patients who have chosen this path can find further comfort on the use of MRI in the monitoring process which should also include periodic endoscopy evaluations as well to make sure.
