Use of Hematopoietic Stem Cell Transplantation to Assess the Origin of Myelodysplastic Syndrome

[Primary myelodysplastic syndrome in children]
Abstract:
Primary MDS is a group of heterogenous clonal haematopoetic disorders. In a third of patients MDS terminates as acute myeloid leukaemia, usually resisitant to treatment, while the others succumb due to infections and haemorrhage. Conservative managements of MDS (chemotherapy, haematopoetic growth factors, modulation of cytokine network) are unsuccessful, while the bone marrow transplantation is the only definite treatment. We reviewed clinical and haematological presentations, frequency of dysplastic features, histological and cytogenetic findings in 29 children with primary MDS. Indications for haematological evaluation in our patients were symptoms and signs of isolated or combined cytopenias, fever of unknown origin and frequent infections. Hepatosplenomegaly was found in 19 (65%) patients, while this pattern was found in 10% of adult patients. Normochromic anaemia was found in 25 (86%) patients and thrombocytopenia in 23 (76%). Patients presenting pancytopenia had the lowest probability of survival. Degree of dysplasia, histology and kariotype of bone marrow had no influence on survival rates. Prognostic factors in paediatric MDS are of limited significance, as MDS in children is an absolute indication for bone marrow transplantation.
Insights
Primary Myelodysplastic Syndromes (MDS) in children are serious blood disorders. Bone marrow transplantation is the only effective treatment, as other therapies and prognostic factors show limited significance.
Area of Science:
- Hematology
- Pediatric Oncology
- Stem Cell Transplantation
Context:
- Primary Myelodysplastic Syndromes (MDS) are heterogeneous clonal hematopoietic disorders in children.
- MDS can progress to acute myeloid leukemia or lead to fatal infections and hemorrhage.
- Current conservative management strategies are largely unsuccessful.
Purpose:
- To review the clinical and hematological presentations, dysplastic features, and histological and cytogenetic findings in 29 children with primary MDS.
- To evaluate the significance of prognostic factors in pediatric MDS.
- To underscore the role of bone marrow transplantation in treating pediatric MDS.
Summary:
- A review of 29 pediatric primary MDS cases revealed common indications for evaluation including cytopenias, fever, and infections.
- Hepatosplenomegaly (65%), normochromic anemia (86%), and thrombocytopenia (76%) were frequent findings.
- Pancytopenia was associated with lower survival, but dysplasia, histology, and karyotype did not significantly influence outcomes.
Impact:
- Prognostic factors in pediatric MDS have limited significance.
- Bone marrow transplantation is the definitive treatment for pediatric MDS.
- Early identification and transplantation are crucial for improving outcomes in children with MDS.
