Congenital malformation in children with acute leukemia: Single center report

Abstract

Introduction:Leukemia is a multifactorial disease. Some genetic syndromes is well known related to leukemia. We evaluated non-syndromic malformation and leukemia relation.Materials and Methods: 288 patients diagnosed with acute leukemia are included the study. 201 patients with non-malign hematologic disease are accepted as a control. Syndromic children were excluded both group. All children were examined according to ICD-10th, Chapter XVII for congenital malformation. The type and number of malformations were compared both group.Results: There were no differences between leukemia and control group in terms of age at diagnosis, gender, consanguinity between parents, parents age at birth, family history of cancer and pregnancies of mother. Congenital malformations were more observed in leukemic population (p<0.001). The most common malformation in the control group was on the skin. Whereas the most common malformation in leukemic children was seen in the circulatory system, second region was skin. Having circulatory system malformation explained 12.53 high of the leukemia risk.Conclusions: Malformations were more common in leukemic children. We found that having a circulatory system malformation significantly increased the risk of leukemia. But the risk was very high previous study. This related to we evaluated echocardiography result which is common use for basal test.
