- Tumors are “staged” in order to help design a treatment plan. The TNM system is common to all solid tumor classification systems, with T showing the size of the primary tumor, N indicating the presence of affected regional lymph nodes, and M showing the presence or absence of distant metastases.
- The staging is then classified into categories which have treatment and prognostic significance. In the case of colorectal cancer, two of the more commonly used staging systems are the Astler-Coller and Dukes’ methods.
