Prognostic value and differences of the sixth and seventh editions of the UICC/AJCC staging systems in nasopharyngeal carcinoma.
The aim of this study was to identify the prognostic value and differences between the 6th and 7th International Union Against Cancer/American Joint Committee on Cancer staging systems in nasopharyngeal carcinoma. ⋯ The revisions of the 7th edition of the staging system are acceptable with regard to the distribution of patient classifications and the separation of survival curves. Moreover, this study will help to develop a better classification system and to better identify the appropriate treatment regimens in nasopharyngeal carcinoma.
