In oncology, “to stage ” a patient implies two intentions. The first uses clinical examination and investigations to describe the extent of disease to permit a rational treatment strategy to be formulated. The second employs an agreed classification system to categorize extent of disease within risk hierarchies that predict outcome following conventional treatment strategies. For the latter, the foremost priority is given to the risk of death and is provided by the joint TNM classification of the International Union Against Cancer (UICC) and the American Joint Committee on Cancer (AJCC), a discussion about which will comprise the majority of this chapter. In the creation of the TNM, a strong emphasis is paid to ensure that the classification is both useful for clinicians and researchers, while also being applicable in regions of the world where nasopharyngeal carcinoma (NPC) has its highest incidence. These goals may engender conflict between the latest scientific discoveries and practical application in jurisdictions, where such advances are difficult to implement. This is particularly relevant to NPC and often some compromise is needed to permit all stakeholders to embrace an international classification.
