Guide for use:

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

Applies to all cancer stage groupings where a staging classification other than the standard TNM classification is used.

Choose the lower (less advanced) stage category when there is any uncertainty.

The relevant cancer stage grouping source will be indicated in the data element Cancer staging-cancer staging scheme source, code N[N] and if applicable, the related edition number will be recorded in data element Cancer staging-cancer staging scheme source edition number, code N[N].

A separate data element captures the extent of the primary cancer based on the TNM stage classification.

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.
