The older Dukes staging system 42 for CRC and its later modifications (mainly
the Modified Dukes-Astler-Coller staging - MAC 43, 44) is a pathological staging
based on resection of the tumor and measures the depth of invasion through
the mucosa and bowel wall. It does not take into account the level of nodal
involvement or the grade of the tumor. It is, however, still widely used in
surgical publications in Belgium and other European countries.
Based on different sources 40, 41, 45, 44 we produced a comprehensive overview of
the TNM stages for CRC and their correlates with Dukes and MAC
classifications (Table 4).
