Treatment of Hodgkin's disease in children with VAMP (vinblastine, adriamycin, methotrexate, prednisone) and VEPA (vinblastine, etoposide, prednisone, adriamycin).

Treatment of Hodgkin's disease in children should be directed at maximizing cures and minimizing the long-term effects of alkylating agents, anthracyclines, and bleomycin. In this study methotrexate and etoposide were used in the VAMP/VEPA regimens to treat 60 clinically staged pediatric patients with Hodgkin's disease. Twenty-nine patients with stages I-IIA received four courses of VAMP plus low-dose radiotherapy. Thirty-one IIA bulky disease and IIB-IVB patients received four or six courses of VEPA plus low-dose radiotherapy. There were 6 partial remissions after the completion of chemotherapy and all of these patients relapsed, but 4 were successfully salvaged with ABMT. Two patients have died. The 3.1-year overall survival rate is 97% (100% VAMP, 94% VEPA) and the event-free survival rate is 88% (97% VAMP, 77% VEPA). These results suggest that VAMP is a reasonable treatment for low stages of Hodgkin's disease, but more advanced disease is not adequately treated by VEPA and low-dose radiotherapy.

History of pediatric hematology-oncology in the Czech Republic.

Specialized treatment for children with hematologic and oncologic diseases in the Czech Republic has a relatively short history. Dr. Josef Koutecky in 1964 was the first to organize the discipline of oncologic treatments and started a department that has since grown to include six other senior members. They treat over 250 new patients a year (approximately 150 malignant tumors) with an incidence similar to that in other European nations. Most are treated on cooperative group protocols with other centers in Europe and North America. Over 30 children also receive bone marrow transplants yearly from this group. Hematologic diseases including leukemia were first treated by D.r. O. Hrodek since the late 1950s in the Second Department of Pediatrics in Prague. Eight other centers in the Czech Republic besides Motol treat children with leukemia. Since 1985 they have followed the Berlin-Frankfurt-Münster (BFM) protocols for patients with acute lymphoblastic leukemia (ALL) and acute myeloblastic leukemia (AML). The Motol Hematology Section does about 20 transplants a year. New molecular biology laboratories in both sections aid the diagnosis and follow-up of the patients.
