[The role of local surgical and radiological control in the treatment of soft tissue sarcoma sensitive to chemotherapy in children. Report of Polish Pediatric Solid Tumors Treatment Group].

In this paper the role local surgical and radiological control in the treatment of soft tissue sarcomas in children was analyzed. All children were treated according to CWS-91 and SIOP-IV protocols. Eighty three children with RMS A + E, EES/PNET, SS, UDS were included in the analysis. The primary surgery consisted of R0 (5%), R1 (18%) or R2 (16%) resection. In majority of cases (61%) primary surgical intervention was limited to diagnostic biopsy. Conventional or hyperfractionated radiotherapy was performed in 42.8%, 73.8% and 75% of children with disease stage II, III and IV, respectively. Delayed surgery was performed in 20 out of 53 (37.7%) children with stage III of the disease. In 5 patients without primary focus (urinary bladder in 3 and prostate in 2 cases) removed, progression of the disease occurred. In 5 children (stage IV) with progression of the disease no secondary surgery was performed. In 4 of them the primary tumor exceeded 10 cm in diameter. No delayed surgery was performed in 69% of relapsed children with stage III of the disease. Planned radiation therapy was not performed in 15.9% of cases. Primary local surgical control of primary tumor is of great importance for remission duration. In children who underwent delayed surgery the estimated EFS was of 0.7, in comparison with 0.5 EFS of those without secondary surgical treatment.

[Treatment outcome for myelodysplastic syndromes (MDS) obtained by the Polish Children's Leukemia/Lymphoma Study Group].

Fourty children with MDS treated in seven centres of The Polish Children's Leukemia Lymphoma Study Group in period 1975-1998y were included to the study. In 16 children RAEB-T, in 2 CMML in 10 RA and in 12 RAEB were diagnosed. Our and literature data showed that BMT is the best therapy for children with MDS. For children, who don't have a donor for BMT. Roacutan therapy seems to be the most effective.

[Hodgkin's disease in two children of mother treated with nitrogranulogen].

Hodgkin's disease was diagnosed in a 12-year old boy and a 2-year old his sister whose mother had been treated with repeated cycles of nitrogen mustard for optic neuritis. The mother received the first treatment two years prior to the boy's birth, and subsequently, in recurrent optic neuritis, three years prior to the birth of the girl.

[Treatment results for rhabdomyosarcoma in children].

The results of treatment in 45 children with rhabdomyosarcoma was presented. Two-years survival was achieved in 63% and five-year in 45%. The importance of location and group of clinical progression discussed was importance prognostic factors in rhabdomyosarcoma.

Standard and intermediate risk acute lymphoblastic leukemia in Poland: a report of the Polish Children's Leukemia/Lymphoma Study Group.

A total of 527 children with acute lymphoblastic leukaemia (ALL) from the most frequent risk groups: standard risk group (SRG) and intermediate risk group (IRG) were treated between 1987 and 1991 according to an intensified treatment program (based on the BFM protocol) including the use of an intermediate dose of methotrexate in the IRG. A comparison of the treatment results in this group from 513 children treated between 1981 and 1987 indicates that the chance for a 6 year event-free survival has increased to 73% (previously 55%).

[Once again about the early diagnosis of Hodgkin's disease].

We describe the initial presentation of Hodgkin's disease, which 40 years ago was generally not diagnosed until its advanced stages. The diagnosis is now being made earlier. The initial symptoms of Hodgkin's disease are described; this may facilitate earlier diagnosis.

[Results of treatment for severe acquired aplastic anemia in children].

The authors evaluated results of treatment of 106 children with acquired aplastic anemia. The patients were divided into 3 groups depending on the severity of their disease. Thirty-nine patients were classified as very severe, 30 as severe and 37 as non-severe according to the modified Camitta criteria. Among them, 47 children were treated with oxymetholone and prednisolone. In this group 32 died. Antilymphocyte globulin (ALG) was given to 48 patients and 20 received cyclosporin A (CsA). The results obtained by these two methods are nearly the same and 5 year survival was 61% and 59% respectively. Bone marrow was transplanted in only one child, who is still in complete remission. Statistical analysis showed a steady increase in incidence of aplastic anemia in the years 1987-1989, which might coincide with the Czarnobyl explosion. However, further research is required to prove this point.

[Malignant neuroectodermal tumor of the arm in a 15-year-old girl successfully treated with chemo- and radiotherapy].

In a 15-year-old girl with right upper arm tumor diagnosed at first as neuroblastoma, the second histopathological examination revealed PNET. In spite of the advanced stage of disease (IIIrd or IVth) surgical excision was not performed but chemotherapy (8 courses of VADRAC and 8 courses of VP16 + CDDP) and radiotherapy (40 Gy) was administered. After 4 initial cycles all symptoms of the disease disappeared. The child remains in CCR for 60 months, including 40 months of therapy.
