Long-term risk and characteristics of cerebrovascular events after upper body radiotherapy among childhood cancer survivors in the DCCSS-LATER cohort.

Cerebrovascular events (CVEs) are serious late adverse events among childhood cancer survivors. We estimated the incidence and risk factors of symptomatic CVEs and described the clinical characteristics among childhood cancer survivors after upper body radiotherapy. The Dutch Childhood Cancer Survivor Study LATER cohort study includes 5-year childhood cancer survivors diagnosed View Article and Find Full Text PDF

Clinical Characteristics of Pathogenic ACAN Variants and 3-Year Response to Growth Hormone Treatment: Real-World Data.

Introduction: Heterozygous variants in the ACAN gene may underlie disproportionate short stature with characteristically accelerated bone age (BA) maturation and/or early-onset osteoarthritis (OA).

Methods: The objective of this study was to describe phenotype, analyze genotype-phenotype correlations, and assess the response of growth hormone (GH) treatment in children with a heterozygous ACAN variant. Thirty-six subjects (23 boys, 13 girls) with ACAN deficiency and treated for ≥1 year with GH were identified in the Dutch National Registry of GH treatment in children.

Progress against non-Hodgkin's lymphoma in children and young adolescents in the Netherlands since 1990: Stable incidence, improved survival and lower mortality.

Background: With epidemiologic analyses of population-based trends in incidence and outcomes, we ascertained progress against non-Hodgkin's lymphoma (NHL) in children and young adolescents in the Netherlands since 1990.

Methods: Tumour characteristics were extracted from the Netherlands Cancer Registry for patients aged <18 years at diagnosis, between 1990 and 2015. Mortality data for 1980-2016 were derived from Statistics Netherlands.

Significant improvement in survival of advanced stage childhood and young adolescent cancer in the Netherlands since the 1990s.

Background: This is the first national study on trends in cancer survival and mortality for children and young adolescents in the Netherlands including unique information on stage at diagnosis.

Methods: All neoplasms in patients <18 years, diagnosed between 1990 and 2015 (N = 14,060), were derived from the Netherlands Cancer Registry. Cohort and period survival analyses were used to estimate observed survival (OS).

Progress against childhood and adolescent acute lymphoblastic leukaemia in the Netherlands, 1990-2015.

We assessed the epidemiologic progress against childhood and adolescent acute lymphoblastic leukaemia (ALL) in the Netherlands over a 26 year period. ALL patients <18 years were selected from the Netherlands Cancer Registry and the Dutch Childhood Oncology Group. Trend analyses were performed over time and by age group and ALL subtype.
