Lymphomas are the third most frequent malignancies in childhood. The Hungarian Pediatric Oncology Group was founded in 1971, and since then the same chemotherapeutic protocols have been used in the whole country. In this study we analyzed the data of childhood Hodgkin's lymphoma in Hungary in the last 11 years (1988-1998). We also compared our results with the international (German) data. The incidence of Hodgkin's lymphoma (0-15 years) was 7.1/1,000,000 child/year (the same for non-Hodgkin's lymphoma was 7.5/1,000,000/year); 5.5% of all pediatric malignancies in Hungary). The patients were treated according to the German DAL-HD-82 and 90 protocols. The therapy consisted of 2-6 cytostatic blocks, depending on the stage, followed by involved field irradiation. The overall survival was 94.7+/-2.0% at 5 years and 91.9+/-2.7% at 10 years. These results are very similar to the German data: 94% at 5 years and 93% at 10 years. The good results are due to the well organised network and the uniformed treatment. The results may be ameliorated by using autologous bone marrow transplantation.
