SLIDE 22 NOTES: A brief look at the five models investigated in depth as part of this workshop shows that the surveillance patterns differ substantially. Some base surveillance strategies contingent on the size of the initial adenoma, some don’t. Most use a 3-year surveillance schedule. And they differ as to whether a different surveillance regimen is enacted for advanced adenomas.

What none of the models appear to have is any tailoring of surveillance on the basis of age. But the data suggest that in practice, age is an important determinant of the frequency of surveillance.
