Proposal for a modified T-classification for oral cancer. The DOSAK
1Department of Maxillo-facial Surgery, University Medical School, DOSAK Central Tumour Registry/Frankfurt am Main, Germany.
Abstract:
The UICC plans to publish a modification of the TNM system. A proposal for a T category is calculated out of the data from the DOSAK tumour registry containing more than 3000 cases of primary squamous cell carcinomas of the oral cavity & oropharynx. By adding tumour thickness as a factor of the T component, the prognostic relevance of the classification is enhanced.
