Dasatinib-induced Chylothorax in Chronic Myelogenous Leukemia in Pediatric Patient: Report of a Case and Review of Literature.

Dasatinib is a second-generation potent and efficacious oral tyrosine kinase inhibitor frequently used for imatinib-resistant or intolerant BCR-ABL-positive chronic myeloid leukemia and for Philadelphia chromosome-positive acute lymphocytic leukemia. Dasatinib is known to cause adverse pulmonary events such as chylothorax and has been described in the adult literature but not pediatric literature. The authors present a pediatric case of dasatinib-related chylothorax, subsequent management, and a review of the literature of adult cases with dasatinib-related chylothorax.

An accurate DNA damage response pathway is critical for the repair of DNA double-strand breaks. Repair may occur by homologous recombination, of which many different sub-pathways have been identified. Some recombination pathways are conservative, meaning that the chromosome sequences are preserved, and others are non-conservative, leading to some alteration of the DNA sequence.
