[Classification of malignant tumours of salivary glands by TNM system]. / Klasifikatsiia na zlokachestvenite tumori na sliunchenite zhlezi po TNM sistema.

After a brief historical review on TNM classification of malignant tumours, a clinical (pre-treatment) and pathological (post-surgical) classification of the tumours of the salivary glands, is presented that has been proposed by the International Union for cancer control. The stages for the determination of the differentiation of the primary tumour--G are described as well as the grouping of the patients in four stages on the base of the data from the TNM categories. It has been underlined that the use of the unified TNM classification of malignant tumours of salivary glands is of importance for the improvement of the quality of the therapeutic work, for the improvement of the national and international collaboration in that section of oncology.

Representative planes of dose distribution for intracavitary radiotherapy of cancer of the cervix.

Four different frontal planes have been evaluated for their usefulness in considering the dose distribution from intracavitary applications for carcinoma of the uterine cervix, in relation to the subsequent planning of supplementary external beam therapy. For the primary tumour and its immediate zone of direct invasion the most useful planes are those passing through the radioactive sources in the body of the uterus. Not one of the planes examined gave satisfactory information concerning the dose in the regional lymph node areas. In order to combine the dose distributions from intracavitary and supplementary external beam irradiation, it is found that every case must be considered individually, particularly in regard to the degree of anterversion or retroversion of the uterus. The dose in the lymph nodes may be calculated directly from coordinates determined by the authors, for each specific regional lymph node group.
