A protective effect of childhood vaccinations on leukemia risk, particularly acute lymphoblastic leukemia (ALL), has been hypothesized, though findings are inconsistent. We used a nationwide cohort of Danish children born 1997-2018 (n = 1,360,230), to examine associations between childhood vaccinations and leukemia (<20 years) using registry data (follow-up: December 31, 2018). Cox proportional hazard models with age as the underlying time estimated hazard ratios (HRs) for leukemia (any, ALL, acute myeloid [AML], and other), comparing vaccinated with unvaccinated children.

Background: The management of pediatric acute myeloid leukemia (AML) is based on the prognostic risk classification of initial leukemia. Targeted next-generation sequencing (NGS) is a reliable method used to identify recurrently mutated genes of pediatric AML and associated prognosis.
Methods: In this study, we retrospectively evaluated the prognostic, and therapeutic utility of a targeted NGS panel covering twenty-five genes, in 21 children with de novo and 8 with relapsed or secondary AML.

Background: Few studies have investigated associations between per- and polyfluoroalkyl substances (PFAS) and childhood cancers. Detectable levels of PFAS in California water districts were reported in the Third Unregulated Contaminant Monitoring Rule for 2013-2015.
Methods: Geocoded residences at birth were linked to corresponding water district boundaries for 10,220 California-born children (aged 0-15 years) diagnosed with cancers (2000-2015) and 29,974 healthy controls.

Background: Childhood obesity can result in adverse health outcomes. The objectives of this study were to describe the prevalence of obesity and determine the association between obesity at cancer diagnosis and event-free survival (EFS) and overall survival (OS) in children diagnosed with cancer in Canada.
Methods: The authors conducted a retrospective cohort study using the Cancer in Young People in Canada database, including all children with newly diagnosed cancer aged 2-18 years across Canada from 2001 to 2020.
Langerhans cell histiocytosis (LCH), juvenile xanthogranuloma (JXG) family lesions, and Rosai-Dorfman-Destombes disease (RDD) are now classified by the World Health Organization (WHO) under the heading of histiocytic/dendritic cell neoplasms. Each disease may manifest as a focal lesion, as multiple lesions, or as a widespread aggressive systemic disease with visceral organ involvement. Erdheim-Chester disease (ECD) is a rare systemic disease process of adults with limited cases in children.
