In brief: Complicated

Measurement of lesions at CT is not a trivial task.
Measurement in the axial plane in two dimensions may not reflect the volume of the lesion. The measurement is affected by slice thickness and window and level settings. RECIST 1.1 is a standard for tumor measurement, but it seems outdated with modern CT. Development of new lung lesions in high risk colon ca is bad, size willnot affect therapy.
