Background: Venous thromboembolism (VTE) is a frequent complication of childhood acute lymphoblastic leukemia (ALL).
Objectives: We aimed to identify molecular markers and signatures of leukemia microenvironment associated with VTE in childhood ALL, by dual-omics approach of gene expression (GEP) and DNA-methylation profiling.
Patients/methods: Eligible children were aged 1-21 years old with newly diagnosed ALL enrolled on the Dana Farber Cancer Institute 16-001 trial with available RNA sequencing data from bone marrow at diagnosis.
Treatment of acute lymphoblastic leukemia (ALL) is associated with neurocognitive deficits in young children. While computerized measures have been utilized in pediatric oncology research, they exclude patients below the age of 4 years. Patients enrolled on "Treatment of Newly Diagnosed Acute Lymphoblastic Leukemia in Children and Adolescents" were offered participation in an optional neurocognitive study.
