ABSTRACT
The prognostic significance of so-called organ sites was investigated in 585 cases with carcinoma of the oral cavity and lips. For the subsamples studied the numerical distribution of TNM categories, life tables and life table comparisons were computed. This produced the following results:
1. There is no demonstrable difference in prognosis between identical T catagories in the organs of the oral cavity. 2. In some cases there is a significant difference between identical N categories in organs of the oral cavity. In the No category this is, however, attributable to the substantial differences in the numerical distribution of T categories. By contrast, a logical explanation for the computationally demonstrable significant differences in the Nx category is not available. The problem is currently being investigated. 3. An assessment of identical TN combinations in the "organs" of the oral cavity proved to be impossible on account of the inadequate number of cases available. The so-called "organ localization" of primary tumours in the oral cavity need not - at least for the time being - be accorded any prognostic relevance. The findings should, however, be re-examined on the basis of greater numbers.
