Background: The prevalence and characteristics of household material hardship (HMH) in families of children with advanced cancer and its association with parent distress are unknown and herein described.

Methods: Parents of children aged ≥2 years with advanced cancer at five cancer centers completed baseline surveys as part of the PediQUEST Response trial. HMH (housing, energy, and food) was operationalized as binary (≥1 HMH domains), ordinal (zero, one, or two or more HMH domains), and housing based (none, nonhousing [food and/or energy], only housing, or housing + other).

High-quality communication is essential for the optimal care of children with cancer and their families. There are opportunities for pediatric oncologists to engage in clear and compassionate prognostic communication across the disease trajectory including at the time of diagnosis, disease recurrence or progression, and end of life. Contrary to previously held beliefs, prognostic disclosure supports parental hope and meets the needs and expectations of families who prefer honest conversations about prognosis.

Importance: Pediatric palliative care treats patients with a wide variety of advanced illness conditions, often with substantial levels of pain and other symptoms. Clinical and research advancements regarding symptom management for these patients are hampered by the scarcity of data on symptoms as well as an overreliance on clinician report.

Objective: To provide a detailed description of the symptoms among patients receiving pediatric palliative care based on parental report via a validated, structured symptom assessment measure.

Background: Radiotherapy is often deferred in very young children with medulloblastoma, in favor of more intense chemotherapy and stem cell rescue; however, posterior fossa radiation has been shown to improve overall survival (OS) and event-free survival compared with adjuvant chemotherapy alone. This study was performed to assess the OS, recurrence-free survival (RFS), patterns of failure, and clinical toxicity for children aged five and under who received focal proton radiation to the tumor bed alone.

Procedure: From 2010 to 2017, 14 patients with newly diagnosed medulloblastoma at one institution received tumor bed irradiation following surgery and chemotherapy.

Introduction: Including children in medical conversations is considered the standard of care for children with cancer. However, previous qualitative research has raised concerns about how the child's presence impacts the parent's communication experience. The current study examines the frequency and impact of child presence during a serious medical conversation on the parent's communication experience in pediatric oncology.

Background: Despite growing evidence and support for shared decision making, little is known about the experiences of parents who hold more active roles than they wish.

Methods: This was a prospective cohort study of 372 parents of children with cancer and their oncologists at 2 academic pediatric hospitals. Parents were surveyed within 12 weeks of the diagnosis, and they were assessed for associated factors and outcomes of holding a more active decision-making role than they preferred.

Background: Pediatric cancer-related fatigue is prevalent and significantly impairs health-related quality of life, yet its patterns and correlates are poorly understood. The objectives of this study were to describe fatigue as prospectively reported by children with advanced cancer and to identify the factors associated with fatigue and associated distress.

Methods: Children (age ≥2 years) with advanced cancer (N = 104) or their parents at 3 academic hospitals reported symptoms at most weekly over 9 months using the computer-based Pediatric Quality of Life Evaluation of Symptoms Technology (PediQUEST) system.

Background: Parents of children with cancer have unmet information needs regarding future limitations resulting from cancer or its treatment. Prior research has demonstrated that, in early care discussions, clinicians focus on the acute effects of therapy rather than long-term limitations, partly due to worries of causing distress. The validity of concerns regarding distress is unknown.

This paper aims to review literature published on the support of cancer caregivers with health technology. Eighteen articles were reviewed to better understand cancer caregiving and categorized into four different themes: (1) design guidelines, (2) information facilitation, (3) social support, and (4) multicomponent interventions. Analysis of the current articles revealed that there are substantial gaps in knowledge regarding a range of health technologies that facilitate family caregiver support and its distribution to health institutions.

Few studies have investigated parent preferences for late effects communication during pediatric cancer treatment. We used questionnaire data to assess whether parental preferences for late effects information change over the year after diagnosis. Most parents found this information to be very/extremely important at baseline, assessed soon after diagnosis, (94%, 153/162), 4 months (91%, 147/162), and 12 months (96%, 156/163).
