American Joint Committee on Cancer TNM staging system (8th Edition)[2]
The American Joint Committee on Cancer (AJCC) staging system describes the extent of disease based on the following anatomic factors: size and extent of the primary tumour (T); regional lymph node involvement (N); and presence or absence of distant metastases (M). Nonanatomic prognostic factors (e.g., tumour grade, biomarkers) may be used to supplement the staging of certain cancers.
Staging laparoscopy is also performed to determine the presence of peritoneal or superficial liver metastases in patients who have potentially resectable disease.[47]
