Objectives: Although pediatric cancer often causes significant stress for families, most childhood cancer survivors are resilient and do not exhibit severe or lasting psychopathology. Research demonstrates some survivors may report benefit-finding or positive outcomes following this stressful life event. However, considerably less research has included families of children who are unlikely to survive their illness.

Background: Pediatric brain tumor survivors (PBTS) experience neurocognitive late effects, including problems with working memory, processing speed, and other higher order skills. These skill domains are subserved by various white matter (WM) pathways, but not much is known about these brain-behavior links in PBTS. This study examined the anterior corona radiata (ACR), inferior fronto-occipital fasciculi (IFOF), and superior longitudinal fasciculi (SLF) by analyzing associations among diffusion metrics and neurocognition.

Objectives: This qualitative study examined how families share information and feelings about advanced pediatric cancer from the perspective of both parents and children, as well as how these perspectives vary by child developmental stage.

Methods: Participants (24 mothers, 20 fathers, 23 youth [children and adolescents]) were from a larger longitudinal study at an academic pediatric hospital. Eligible youth had advanced cancer (physician-estimated prognosis of <60%, relapse, or refractory disease), were aged 5-19 years (>8 years old to participate independently), had an English-speaking parent, and lived within 140 miles of the hospital.

Article Synopsis
  • The study aimed to evaluate the effectiveness and safety of stereotactic body radiation therapy (SBRT) in treating pediatric patients with metastatic disease.
  • 16 pediatric and adolescent patients underwent SBRT from 2000 to 2020, showing a median overall survival (OS) of 17 months and a one-year OS rate of 75%.
  • Results indicated excellent local control of tumors, especially for those receiving higher doses (≥100 Gy), with low rates of severe toxicity, suggesting SBRT is a viable treatment option for this demographic.

Background: Central nervous system (CNS)-directed treatments can cause long-term academic, social, and emotional difficulties for children with cancer. However, limited research has examined the emergence of problems longitudinally and has often stratified risk by diagnosis alone. Therefore, this study compared competence and adjustment in children, who did and did not receive CNS-directed treatment, over the first 3 years following a cancer diagnosis.

Purpose: Young individuals face a variety of developmental tasks as they mature into adulthood. For survivors of childhood cancer, growing up may be more difficult due to their illness and late effects from treatment. This study is the first to quantitatively examine perceptions of maturity and how these perceptions contribute to satisfaction with life among young adult survivors of childhood cancer.

Objective: Meaning-making may assist individuals in adaptation to stressful life events, particularly bereavement. However, few studies have examined meaning-making among pediatric populations with advanced illness to understand how this process unfolds before the child's death. This study explores meaning-making pre-bereavement among children with advanced cancer and their parents.

Background: Pediatric hematology, oncology, and hematopoietic cell transplantation (HCT) patients are at increased risk for bloodstream infections. The authors sought to evaluate the influence of a standardized best practice central venous catheter (CVC) maintenance bundle on the burden of and risk factors for mucosal barrier injury (MBI) and non-MBI central line-associated bloodstream infections (CLABSIs) across a common inpatient and ambulatory continuum in this high-risk population.

Methods: A retrospective cohort study of patients with underlying malignancy, hematologic disorders, and HCT recipients with a CVC in place at the time of CLABSI diagnosis in both inpatient and ambulatory settings from January 1, 2012 to December 31, 2016.

Childhood cancer survivors are at risk for impaired psychosocial functioning, but limited research has focused on psychosexual outcomes in young adulthood. This qualitative study examined the perceived impact of childhood cancer on adult survivors' romantic relationships and sexual/physical intimacy. Phone interviews were completed with adult survivors of childhood cancer, exploring the impact of cancer on (1) romantic relationships and (2) sexual/physical intimacy.

Objective: The majority of childhood cancer survivors develop at least one late effect subsequent to treatment (eg, cardiovascular disease and obesity). Consistent engagement in recommended health behaviors may mitigate some of these conditions. Researchers have identified early survivorship as a teachable moment, yet few studies have examined positive health behaviors during this period.

Objective: The Cancer Care Index (CCI), a single metric that sums the number of undesirable patient events in a given time frame (either preventable harm events or missed opportunities to provide optimal care), resulted in a 42% improvement in performance. Our objective was to test the index concept in other service lines to determine whether similar performance improvement occurred.

Study Design: Care indices were developed and introduced in 3 additional service lines: Nephrology (Chronic Kidney Disease Care Index; CKDCI), Pulmonology (Lung Transplantation Care Index; LTCI), and Otolaryngology (Tracheostomy Care Index; TCI).
