Child and family perceptions of satisfaction with neutropenia management in pediatric acute myeloid leukemia.

Purpose: Chemotherapy for pediatric acute myeloid leukemia (AML) is very intensive and many, but not all centers, require extended hospitalization until neutrophil recovery. Child and family preferences, beliefs, and experiences around hospitalization have not been systematically assessed.

Patients And Methods: We recruited children with AML and their parents from nine pediatric cancer centers across the United States for a qualitative interview about their experiences of neutropenia management.

Medical Outcomes, Quality of Life, and Family Perceptions for Outpatient vs Inpatient Neutropenia Management After Chemotherapy for Pediatric Acute Myeloid Leukemia.

Importance: Pediatric acute myeloid leukemia (AML) requires multiple courses of intensive chemotherapy that result in neutropenia, with significant risk for infectious complications. Supportive care guidelines recommend hospitalization until neutrophil recovery. However, there are little data to support inpatient over outpatient management.

Outcome of patients with relapsed or progressive Ewing sarcoma enrolled on cooperative group phase 2 clinical trials: A report from the Children's Oncology Group.

SevenChildren's Oncology Group phase 2 trials for patients with relapsed/progressive solid tumors were analyzed to estimate the event-free survival (EFS) for relapsed/progressive Ewing sarcoma. One hundred twenty-eight Ewing sarcoma patients were enrolled and 124 events occurred. The 6-month EFS was 12.

Impact of COVID-19 Pandemic on Timing of Childhood Cancer Diagnoses.

The COVID-19 pandemic impacted the health care system in unprecedented ways. We reviewed the registry of new cancer patients who presented to the Children's of Mississippi Center for Cancer and Blood Disorders and showed the average number of new pediatric cancer diagnoses dropped during the initial COVID-19 months and rose significantly in June 2020. We must encourage families to seek health care when needed and keep scheduled appointments for routine vaccinations and health maintenance as we know the long-term sequela of delaying health maintenance far outweighs risks at present.

Health Insurance Coverage Disruptions and Cancer Care and Outcomes: Systematic Review of Published Research.

Background: Lack of health insurance coverage is associated with poor access and receipt of cancer care and survival in the United States. Disruptions in coverage are common among low-income populations, but little is known about associations of disruptions with cancer care, including prevention, screening, and treatment, as well as outcomes of stage at diagnosis and survival.

Methods: We conducted a systematic review of studies of health insurance coverage disruptions and cancer care and outcomes published between 1980 and 2019.

Single-Institution Experience of Synovial Sarcoma.

Objectives: The purpose of this study was to investigate the patient population and outcomes of synovial sarcoma at a single institution.

Methods: A retrospective review of the medical records of 28 patients with synovial sarcoma diagnosed from 1992 to 2017 was performed. Demographics, staging, disease location, treatment, and response to treatment were reviewed.

Impact of Race and Socioeconomic Status on Psychologic Outcomes in Childhood Cancer Patients and Caregivers.

Complex relationships between race and socioeconomic status have a poorly understood influence on psychologic outcomes in pediatric oncology. The Family Symptom Inventory was used to assess symptoms of depression and anxiety in pediatric patients with cancer and their caregivers. Separate hierarchical linear regression models examined the relationship between demographic variables, cancer characteristics, socioeconomic status, and access to care and patient or caregiver depression/anxiety.

Identifying patient- and family-centered outcomes relevant to inpatient versus at-home management of neutropenia in children with acute myeloid leukemia.

Efficacy of therapeutic strategies relative to patient- and family-centered outcomes in pediatric oncology must be assessed. We sought to identify outcomes important to children with acute myeloid leukemia and their families related to inpatient versus at-home management of neutropenia. We conducted qualitative interviews with 32 children ≥8 years old and 54 parents.

Off-therapy procedures are not beneficial in pediatric B-cell acute lymphoblastic leukemia.

Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Although curable, approximately 20% of patients relapse. In an effort to detect relapse earlier, our institution performed surveillance bone marrow (BM) and cerebrospinal fluid (CSF) evaluations every 3 months from the end of therapy to 1 year off.

A Novel β-Globin Chain Hemoglobin Variant, Hb Allentown [β137(H15)Val→Trp (GTG>TGG) HBB: c.412_413delinsTG, p.Val138Trp], Associated with Low Oxygen Saturation, Intermittent Aplastic Crises and Splenomegaly.

Hemoglobin (Hb) variants may be associated with low oxygen saturation and exacerbated episodes of anemia from common stressors such as viral infections. These attributes frequently cause increased clinical concern and unnecessary and expensive testing if not considered early in the evaluation of the patient. Some clinically significant Hb variants result in a normal Hb electrophoresis result, which can be method-dependent.

Multimodality Imaging in Pediatric Osteosarcoma in the Era of Image Gently and Image Wisely Campaign With a Close Look at the CT Scan Radiation Dose.

The increasing use of serial multimodality imaging in the management of pediatric osteosarcoma raises concern of over exposure to ionizing radiation in children, especially from repeated computed tomographic (CT) scans. This study reviews the utilization of multimodality imaging in patients with osteosarcoma at our institution and analyzes any potential radiation-related complications. Twenty-eight patients were identified.

Vorinostat Enhances Cytotoxicity of SN-38 and Temozolomide in Ewing Sarcoma Cells and Activates STAT3/AKT/MAPK Pathways.

Histone deacetylase inhibitors (HDACi) have been evaluated in patients with Ewing sarcoma (EWS) but demonstrated limited activity. To better understand the potential for HDACi in EWS, we evaluated the combination of the HDACi vorinostat, with DNA damaging agents SN-38 (the active metabolite of irinotecan and topoisomerase 1 inhibitor) plus the alkylating agent temozolomide (ST). Drugs were evaluated in sequential and simultaneous combinations in two EWS cell lines.

Chondrosarcoma presenting with pulmonary embolism in a 9-year-old girl: a case report.

Chondrosarcoma is a malignant bone tumour common in adults, third to myeloma and osteosarcoma, but is exceptionally rare in children. Here we discuss a 9-year-old girl presenting with occlusive right pulmonary artery neoplastic embolus, resulting from a primary right proximal humerus chondrosarcoma. To the best of our knowledge, this the first pediatric and only second overall case reported in the United States of a neoplastic pulmonary embolus resulting from a primary chondrosarcoma.

Cutaneous Ewing sarcoma: report of 2 cases and literature review of presentation, treatment, and outcome of 76 other reported cases.

Cutaneous Ewing sarcoma is a rare variant that has been poorly characterized and has no standard therapy. We report 2 patients with cutaneous Ewing sarcoma and review 76 other cases reported in the literature for demographics, presentation, treatment, and outcome. Only 2 patients presented with metastatic disease, and only 8 patients developed metastatic disease.

Candidate gene association analysis of acute lymphoblastic leukemia identifies new susceptibility locus at 11p15 (LMO1).

To determine the contribution of susceptibility loci in explaining the genetic basis of acute lymphoblastic leukemia (ALL), we genotyped 29 high-potential candidate genes with 672 tagged single-nucleotide polymorphisms (SNPs) in a sample (163 cases and 251 healthy controls) of Caucasian children. Fifty SNPs in 15 genes were significantly associated with ALL risk at the P < 0.05 level.

Polymorphisms in CYP1A1 and ethnic-specific susceptibility to acute lymphoblastic leukemia in children.

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. The U.S.

Multilocus association of genetic variants in MLL, CREBBP, EP300, and TOP2A with childhood acute lymphoblastic leukemia in Hispanics from Texas.

Background: Hispanic children have both a higher incidence and a poorer outcome in acute lymphoblastic leukemia (ALL). Moreover, a higher incidence for therapy-related acute myeloid leukemia with 11q23 translocations after treatment with topoisomerase II (topo II) inhibitors has been observed in Hispanic children with ALL. We sought to determine the potential role of genetic variants within the topoisomerase IIα gene (TOP2A), within the mixed lineage leukemia gene (MLL) and two of its translocation partners, cyclin AMP response element-binding protein gene (CREBBP) and E1A binding protein gene (EP300) in the increased sensitivity of Hispanic children with ALL to topo II inhibitors.

Ewing sarcoma: prognostic criteria, outcomes and future treatment.

Ewing sarcoma (EWS) is a bone tumor occurring primarily in adolescence and young adulthood. Multi-institutional clinical trials have improved the outcome for patients with nonmetastatic EWS, but not with metastatic EWS. Furthermore, although 30% of EWS recur, multi-institutional studies have not been completed for this high-risk group.
