Background: Subsequent short-latency leukemias are well-described among survivors of childhood cancer. However, late (5-14.9 years from diagnosis, LL) and very late (≥15 years from diagnosis, VLL) subsequent leukemias have not been well studied.

Aobjective: The impact of fine motor impairment among adult survivors of childhood acute lymphoblastic leukemia (ALL) on life after treatment is unknown.

Methods: This study evaluated prevalence and utilized multivariate logistic regression to identify risk factors for fine motor impairment among survivors of ALL, and associations with educational attainment and social independence. Latent class analysis defined social independence (independent, moderately independent, dependent), using employment, independent living, personal care assistance, routine need assistance, driver's license status, and marital status inputs.

Survivors of childhood cancer may experience accelerated biological aging, resulting in premature frailty and death. We used seven measures of biological age in the St. Jude Lifetime (SJLIFE) Cohort to compare biological age acceleration between the SJLIFE Cohort and the third United States National Health and Nutrition Examination Survey controls, explore trajectories of biological age according to cancer treatment and type, and test associations of biological age acceleration with frailty and death (mean follow-up of 26.

Background: Childhood cancer survivors have increased risk of dyslipidemia and atherosclerotic cardiovascular disease (CVD). The aim of this study was to evaluate the prevalence and associated cardiovascular risks of specific lipid abnormalities among childhood cancer survivors.

Methods: Comprehensive lipid panel measurements were obtained from 4115 5-year survivors, with 3406 (mean age at evaluation = 35.

Article Synopsis
  • The study examines the impact of treatment changes for childhood acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL) on physical performance and participation restrictions in survivors compared to their siblings.
  • Researchers analyzed data from 6,511 survivors and 4,127 siblings, finding that survivors had significantly higher rates of performance limitations and personal care restrictions.
  • Despite advancements in treatment over the decades, the prevalence of reduced physical function did not significantly decrease, highlighting the need for ongoing screening and early interventions for cancer survivors.

Objective: This study used childhood cancer survivors as a novel model to study whether children who experience central nervous system (CNS) injury are at higher risk for neurocognitive impairment associated with subsequent late onset chronic health conditions (CHCs).

Methods: Adult survivors of childhood cancer (n = 2,859, ≥10 years from diagnosis, ≥18 years old) completed a comprehensive neurocognitive battery and clinical examination. Neurocognitive impairment was defined as age-adjusted z score < 10th percentile.

Purpose: This study compared the measurement properties for multiple modes of survey administration, including postal mail, telephone interview, and Web-based completion of patient-reported outcomes (PROs) among survivors of childhood cancer.

Methods: The population included 6,974 adult survivors of childhood cancer in the Childhood Cancer Survivor Study who completed the Brief Symptom Inventory-18 (BSI-18), which measured anxiety, depression, and somatization symptoms. Scale reliability, construct validity, and known-groups validity related to health status were tested for each mode of completion.

Background: The objective of this study was to characterize chronic disease, health-related quality of life (HRQOL), emotional distress, and social attainment among long-term survivors of neuroblastoma.

Methods: Chronic health conditions among 136 ≥10-year neuroblastoma survivors (median age, 31.9 years; range, 20.

Purpose: To examine prevalence and predictors of neurocognitive outcomes, social attainment, emotional distress, and health-related quality of life (HRQOL) in long-term survivors of pediatric Wilms tumor (WT).

Methods: One hundred fifty-eight WT survivors (59% female; mean [SD] age 33 [9.1] years; time since diagnosis 29 [9.

Background: Treatment for childhood acute lymphoblastic leukemia has evolved over the past five decades, with moderation of traditional chemotherapy and radiotherapy and the introduction of targeted immune-based and cellular-based therapies. The affect of these changes on late health outcomes has not been assessed. Using data from the The St Jude Lifetime (SJLIFE) Cohort, we aimed to characterise the magnitude of morbidity and patterns of late health outcomes among survivors of childhood acute lymphoblastic leukaemia treated over time.

We report long-term effects of the PROSPER delivery system for universal evidence-based preventive interventions on adolescent conduct problem behaviors (CPBs). A cluster randomized trial included 28 school districts assigned to PROSPER or a control condition. Community-based teams in PROSPER condition school districts selected evidence-based interventions-a family-focused intervention in sixth grade and a school-based intervention the next year; follow-up assessments were conducted through 12th grade.
