The therapeutic application of 89strontium for the relief of pain in 11 cases of carcinoma of the prostate with skeletal metastases is reported. A significant clinical improvement could be observed in 8 of the 11 patients with generalized osseous metastases of prostatic carcinoma after the application of 30 muCi. 89strontium per kg. The effect was long lasting. At the same time an increase of alkaline phosphatase was observed, which was interpreted as an indication of the reactivation of osteoblasts and osteoid peripheral zones owing to beta-emission of the radioisotope in the affected areas. The indications for such therapy are discussed.
The clinical course of 201 patients with malignant non-Hodgkin-lymphomas was analysed according to the Kiel classification. The five-year survival rate of 133 patients with lymphomas of low grade malignancy was 63% in comparison to 23% out of 68 patients with lymphomas of high grade malignancy. Radio- and chemotherapy were used in a different way. Patients with centrocytic-centroblastic lymphomas had the best porgnosis, which was not influenced by the stage of the disease. The poorest prognosis was observered in patients with lymphoblastic lymphomas. These results support the importance of a classification of malignant non-Hodgkin-lymphomas which is not only based on morphological criteria.
