Article: Tetrasomy 8 as a primary chromosomal abnormality in a child with acute megakaryoblastic leukemia. a case report and review of the literature.
[show abstract] [hide abstract]
ABSTRACT: Tetrasomy 8 is a relatively rare chromosomal abnormality in hematological disorders, and is mostly associated with myeloid malignancies and poor prognosis. In a number of cases, tetrasomy 8 has been reported as an accompanying anomaly with other chromosomal changes. In this report, we describe a 14-year-old girl with acute megakaryoblastic leukemia associated with tetrasomy 8 (primary) and trisomy 6, 19 and 20. She died 6 months after diagnosis, suggesting a relatively poor prognosis for AML with tetrasomy 8. To the best of our knowledge, this is the first report of a tetrasomy 8 abnormality associated with subtype FAB M7. Interestingly, this abnormality has not been previously reported in childhood AML patients.Cancer Genetics and Cytogenetics 05/2001; 126(2):166-8. · 1.39 Impact Factor -
Article: Myelodysplastic syndrome associated with monosomy 7 in a child with Bloom syndrome.
[show abstract] [hide abstract]
ABSTRACT: Bloom syndrome is a genomic instability syndrome associated with predisposition to development of various types of malignancy. In this report, we described a 7-year-old boy with Bloom syndrome (BS) and myelodysplastic syndrome (MDS) associated with monosomy 7 and loss of the Y chromosome. To our knowledge, this was the first case with BS showing monosomy 7 and MDS during the early childhood period.Cancer Genetics and Cytogenetics 01/2000; 116(1):44-6. · 1.39 Impact Factor -
Article: Loss of maternal allele in a child with myelodysplastic syndrome and monosomy 7.
[show abstract] [hide abstract]
ABSTRACT: Monosomy 7 or partial deletion of the long arm of chromosome 7 is frequently described in children with myelodysplastic syndrome and acute myeloblastic leukemia. Parental origin of chromosome 7 in children with sporadic monosomy 7 has been examined very rarely. To investigate if monosomy 7 shows parent-of-origin, we have studied a female child with monosomy 7 and de novo myelodysplastic syndrome by a series of polymorphic polymerase chain reaction markers. We found loss of maternal allele and discussed the results with the previous reports.American Journal of Hematology 10/1999; 62(1):49-51. · 4.67 Impact Factor -
Article: Primary myelodysplastic syndrome in children: the clinical experience in 33 cases.
[show abstract] [hide abstract]
ABSTRACT: We describe the clinicomorphological features in 33 cases of primary myelodysplastic syndrome classified according to the FAB classification which presented to a single centre over a 12 year period. Presenting features were typically related to pancytopenia although hepatosplenomegaly and granulocytic sarcomas were far more prevalent than in the adult population. Morphological assessment of the peripheral blood and the bone marrow showed seven patients had refractory anaemia (RA), 13 patients had RA with excess of blasts (RAEB), nine patients had RAEB in transformation (RAEB-t) and four patients had chronic myelomonocytic leukaemia (CMML). The overall mean survival was short (9.9 months) in all the subgroups and the leukaemic transformation rate was high. None of the patients scored 0-1 according to the Bournemouth Scoring System; four patients scored 2 whereas 29 patients scored 3 to 4. We conclude that unlike adults, the myelodysplastic syndromes in children run an aggressive clinical course, irrespective of the FAB subtype, and the pathogenesis of these diseases in paediatric practice warrants scientific scrutiny. Intensive chemotherapy such as the one used in de novo-AML lead to complete remission in some children and these early results suggest that this should be the treatment of choice in paediatric MDS.British Journal of Haematology 11/1992; 82(2):347-53. · 4.94 Impact Factor -
