Chronic myeloid leukemia in a pediatric population in the Congo
Year 2017,
Volume: 4 Issue: 3, 27 - 29, 31.03.2017
Objective:
Chronic myeloid leukemia is a rare hematological malignant disorder among
children and adolescents for which data are scare in Africa. The aim of the
study is to report clinical, biological feature of children with chronic
myeloid leukemia. Additionally, describing cytogenetic response to imatinib
and adherence of children to the drug.
Patients and Methods: A retrospective study was carried out from January 2007 to December
2016 (10 years) in the department of Hematology at the Teaching Hospital in
Brazzaville. Four of 52 patients
admitted during the period for chronic myeloid leukemia, were children. We
collected data from these children’s medical records for analysis.
Results: They
were four adolescents (2 boys and 2 girls) with a median age of 13.75 years
at the time of diagnosis (range 11.2 and 16 years) that presented at the
chronic phase of the the chronic myeloid leukemia. Delay diagnosis was 4 months. All
adolescents presented with a voluminous splenomegaly (median size: 16.75 cm)
and high white blood cells count: 133.37G/L (range: 60.7 and 219 G/L). The
response to imatinib was poor. None patient was adherent to the treatment.
Conclusion:
Chronic myeloid leukemia in children in the Congo is rare. Abdominal pain and
voluminous splenomegaly are the main finding symptoms of the malignancy.
Despite the delayed diagnosis of the disease, children present at chronic
phase. The response to imatinib is poor as children are not adherent to the
treatment.
