pTNM Staging | AJCC 2017
The TNM staging system anatomically classifies malignancies based on the extent of the primary tumour, regional lymph node involvement, and distant metastases. Staging helps physicians decide eligibility for clinical trials, define a patient's prognosis, and determine best treatment options.
The American Joint Committee on Cancer (AJCC) publishes the AJCC Cancer Staging Manual every 6-8 years. This tool is based on the 8th edition (2017) which represents the most up to date TNM staging guide.
