Although the UICC/AJCC's TNM staging of the 7th edition was improved in 2002, there are still shortcomings concerning the prognostic quality. Alternative TNM-based stage-groupings such as the T and N Integer Score (TANIS) where shown to have a better prognostic quality for various kinds of head and neck tumors in the past. The aim of the study was to compare the prognostic value of the 7th edition of the UICC/AJCC TNM-classification for carcinoma of the parotid gland with different TNM-based stage groupings.
