Interpret TNM staging system for solid tumours. T (primary tumour size/invasion): T0-T4. N (regional lymph node involvement): N0-N3. M (distant metastasis): M0 (none) or M1 (present). Combined into Stage I-IV groupings; Stage IV always indicates metastatic disease.
Enter the values for the scenario you are assessing. Interpret TNM staging system for solid tumours. T (primary tumour size/invasion): T0-T4. N (regional lymph node involvement): N0-N3. M (distant metastasis): M0 (none) or M1 (present). Combined into Stage I-IV groupings; Stage IV always indicates metastatic disease. Use the tnm staging result to inform your calculation.
