Guide for use:

Record the extent of the primary cancer at the time of diagnosis of the cancer.

TNM staging applies to solid tumours excluding brain tumours.

The current edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual provides an equivalent and alternative source of TNM stage grouping codes.

Stage groupings using classification systems other than the TNM classification system are recorded separately.

Comments:
Cancer stage is an important determinant of treatment and prognosis, and is used to evaluate new treatments and analyse outcomes. Survival analysis is adjusted by stage at diagnosis and distribution of cancer cases by type and stage.
