[Treatment regimen for children and adolescents with Hodgkin's disease designed to decrease late complications of radiotherapy].

Between 1997 to 1999 in 9 centres of the Polish Paediatlic Leukemia/Lymphoma Study Group, 167 children and adolescents (aged 2-19 years) with stage 1 to IV Hodgkin's disease (HD) were treated according to a regimen with a limited use of radiotherapy (RT). All patients received B-DOPA and MVPP chemotherapy. The number of cycles of chemotherapy was adjusted in respective risk groups. In 13 children with stage IA and IIA disease with favourable prognostic factors chemotherapy alone was used. In other patients the dose of RT applied to lymphatic regions was 15-46,4 Gy. In case of a small tumour at presentation and good response to initial chemotherapy the RT dose was 15-16 Gy. In other cases doses of 25-30 Gy were planned. The use of higher doses, particularly exceeding 35 Gy, in eleven patients, was not justified. Among all the 167 patients, three oftliem (1.2%) with advanced disease (Stage III-1V) did not achieve first remission. The 4-year overall survival (OS), relapse free survival (RFS) and event free survival (EPS) were 99%. 93% and 90%, respectively. Relapses occurred in 8 children (first remission lasted for 4-29 (median = 9 months). All 13 children in whom chemotherapy alone was used remain in first remission. In the group of children who received RT in the dose of 15-16 Gy relapse occurred in one child. Our preliminary analysis indicates that limited use of RT in selected cases of HD in children and adolescents did not show worse results of treatment. However, the assessment of possible influence of this regimen on the decreased rate of late complications requires longer follow-up.

[Extramedullary (bone) relapse 16 months after allo bmt in a 7-year-old girl treated for acute lymphoblastic leukaemia from the second year of life].

7-year-old girl treated for acute lymphoblastic leukaemia since June 1995 after marrow relapse (June 1997) presented with painful oedema of the upper part of left hip and limping, 16 months after allogeneic bone marrow transplantation (BMT). Bone marrow examination excluded medullary relapse. Histopathological investigation of periosteum and bone scrapings revealed massive leukemic infiltration. Radiotherapy resulted in local arrest of the malignant process. However, bone marrow relapse was diagnosed in the child two months later with subsequent death after one month.

[Assessment of the efficacy of treating infections in hematopoietic proliferative diseases: Monotherapy with ceftazidime and tobramycin combined with amoxycillin/ampicillin].

Efficacy of the ceftazidime monotherapy in 120 febrile children with neoplastic diseases and granulocytopenia was compared with that of tobramycin combined with amoxycillin/ampicillin. The obtained results were similar in both types of antibiotic therapy. However, granulocytopenia was higher and septicemia was more frequent in children treated with ceftazidime. Isolated bacteria were more sensitive to ceftazidime than to tobramycin with amoxycillin/ampicillin. Both regimens were tolerated well. Despite a low number of patients in both groups, one may conclude that ceftazidime is more efficient in patients with granulocytopenia. Less adverse reactions, lower number of infections, less frequent medical procedures, elimination of the potentially toxic aminoglycosides and lower cost of therapy advocate the use of ceftazidime monotherapy.

[Stages of B-lymphocyte differentiation in acute lymphoblastic leukemia].

Blasts phenotype was determined in 61 children with the acute lymphoblastic leukemia. Non-T-cell acute lymphoblastic leukemia was diagnosed in 51 children. Stages of blasts differentiation were determined with the aid of monoclonal antibodies set using alkaline phosphatase-anti-alkaline phosphatase technique. Blasts in 50 patients belonged to B subpopulation confirmed by the presence of panB CD19 and CD22 antigens. Common antigen was seen in 76.5% of the examined patients with non-T-cell acute lymphoblastic leukemia. Cases of non-T-cell acute lymphoblastic leukemia were divided into 8 subgroups depending on the antigens of B-cells differentiation. An identification of pre-B subgroups of the acute lymphoblastic leukemia indicates heterogenicity of the acute lymphoblastic leukemias in childhood and enables their classification into groups corresponding to the early stages of lymphoblasts maturation.
