[Treatment results in localized forms of reticulosarcoma and Ewing's sarcoma in children]

The results of treatment of 53 cases of pediatric localized Ewing's sarcoma and bone reticulosarcoma were analysed. Chemoradiotherapy is a procedure of choice in bone marrow sarcoma treatment: while overall five-year survival was 28.4 +/- 6.2%, it was as high as 64.9% in cases of combined treatment (total focal dose of at least 50 Gy + polychemotherapy). Two cases of osteo- and chondrosarcoma development in exposed bone are described.
