TNM Classification of Malignant Tumours (TNM) is the cancer staging system developed and maintained by the International Union Against Cancer (UICC) to achieve consensus on one globally recognised standard for classifying the extent of spread of cancer. The TNM classification is also used by the American Joint Committee on Cancer (AJCC) and the International Federation of Gynecology and Obstetrics (FIGO). In 1987, the UICC and AJCC staging systems were unified into a single staging system.
Additional recommended knowledge
Each tumor has its own TNM classification. Not all tumors have TNM classifications, but most do. For instance, there is no TNM classification for brain tumors, and prostate cancer is staged based on the independent Gleason score.
The general outline for the TNM classification is below. The values given in parenthesis give a range of what can be used for all cancer types, but not all cancers use this full range.
Mandatory parameters ('T', 'N', and 'M')
Use of an "X" instead of a number or other suffix means that the parameter was not assessed.
For the T, N and M parameters exist subclassifications for some cancer-types (e.g. T1a, Tis, N1i)
Uses and aims
Some of the aims for adopting a global standard are to:
Since the number of combinations of categories is high, combinations are grouped to stages for better analysis.
