TNM Supplement 1993

This 1993 supplement facilitates uniform application of the TNM classification. The supplement provides explanations and examples that will solve practical problems when using TNM on a daily basis. It spells out the requirements for pathological classification (pT, pN) and contains recommendations for classification of new tumour sites and entities which are not yet formally included in the TNM system. It also includes proposals for optimal expansion of TNM subsets where more detailed data are needed without altering the basic rules of the TNM classification.
