Article Synopsis
  • Subcutaneous patient-derived xenografts (PDXs) are utilized for childhood cancer research, and this study establishes a resource of 68 early passage PDXs from 65 pediatric solid tumor patients.
  • Genomic profiling reveals low mutational similarity in about 30% of paired patient tumors (PTs) and PDXs, with aggressive tumor subclones influencing the major tumor clone in PDXs, highlighting a possible immune suppression of these subclones in patients.
  • The study shows that PDXs mirror PTs in copy number and transcriptomic profiles, and identifies a specific gene fusion, LRPAP1-PDGFRA, emphasizing the influence of immune responses on tumor evolution in childhood cancers.

Cancer survivors are at an increased risk of thromboembolism compared to the general pediatric population. Anticoagulant therapy decreases the risk of thromboembolism in cancer patients. We hypothesized that pediatric cancer survivors are in a chronically hypercoagulable state compared to healthy controls.

Purpose: Infant and young childhood medulloblastoma (iMB) is usually treated without craniospinal irradiation (CSI) to avoid neurocognitive late effects. Unfortunately, many children relapse. The purpose of this study was to assess salvage strategies and prognostic features of patients with iMB who relapse after CSI-sparing therapy.

Background: Low-middle-income countries (LMICs) share a substantial proportion of global surgical complications. This is compounded by the seemingly deficient documentation of postsurgical complications and the lack of a national average for comparison. In this context, the implementation of the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) that compares hospital performance based on postsurgical complication data provided by a wide array of centers, could be a major initiative in a resource-challenged setting.

Purpose: To study the efficacy and tolerability of valproic acid (VPA) and radiation, followed by VPA and bevacizumab in children with newly diagnosed diffuse intrinsic pontine glioma (DIPG) or high-grade glioma (HGG).

Methods: Children 3 to 21 years of age received radiation therapy and VPA at 15 mg/kg/day and dose adjusted to maintain a trough range of 85 to 115 μg/mL. VPA was continued post-radiation, and bevacizumab was started at 10 mg/kg intravenously biweekly, four weeks after completing radiation therapy.

We describe the case of a 12-year-old Hispanic male with a clinical and molecular diagnosis of Simpson-Golabi-Behmel Syndrome (SGBS) who subsequently developed metastatic medulloblastoma. While individuals with SGBS have been documented to have increased risk for intra-abdominal tumors such as Wilms tumor and neuroblastoma, medulloblastomas, or CNS tumors in general, have not been reported in patients with this syndrome. Our patient was clinically diagnosed with SGBS as an infant.

Purpose: To describe the demographic and clinical features and outcomes for children and adolescents with primary CNS lymphoma (PCNSL).

Experimental Design: A retrospective series of children and adolescents with PCNSL was assembled from 10 cancer centers in 3 countries.

Results: Twenty-nine patients with a median age of 14 years were identified.

Article Synopsis
  • The study aimed to assess the frequency and causes of bilateral ocular trauma at the Khyber Institute of Ophthalmic Medical Sciences over a seven-year period.
  • Out of 1551 hospitalized ocular trauma patients, 46 (2.9%) had bilateral damage, primarily due to landmine and dynamite blasts, with most victims being young males aged 16 to 40.
  • The findings revealed that treatment resulted in poor visual outcomes, with only 28.2% of patients regaining significant vision post-injury.
