Importance: Pediatric patients with cancer commonly experience severely bothersome symptoms. The effectiveness of routine symptom screening with symptom feedback and symptom management care pathways is unknown.
Objective: To determine whether thrice-weekly symptom screening with symptom feedback and management care pathways, compared with usual care, improves overall self-reported symptom scores measured by the Symptom Screening in Pediatrics Tool (SSPedi) in pediatric patients with cancer.
Background: Socioeconomic disparities exist in pediatric patients with hematologic malignancies, leading to suboptimal survival rates. Social determinants of health impact health outcomes, and in children, they may not only lead to worse survival outcomes but carry over into late effects in adult life. The social deprivation index (SDI) is a composite score using geographic county data to measure social determinants of health.

The primary objective was to describe the adaptation process and specific adaptation decisions related to symptom management care pathways based on clinical practice guidelines. The secondary objective evaluated if institutional factors were associated with adaptation decisions.

We reviewed the last 40 years of data to see how pediatric cancer care has evolved. Methods We retrospectively analyzed SPIRS data from 1981 through 2020 in five-year increments, looking at numbers of new diagnoses, care delivery sites, and trial enrollment in Children's Oncology Group (COG) studies.

The current study aimed to examine the relationship between health disparities, as measured by the social deprivation index, and mortality in paediatric oncology patients using a population-based national database.
Methods: In this cohort study of children across all paediatric cancers, survival rates were determined using the Surveillance, Epidemiology, and End Results (SEER) database from 1975 to 2016.
Purpose: Children with relapsed/refractory central nervous system (CNS) tumors require novel combinations of therapies. Irinotecan and temozolomide (IT) is a frequently used therapy with an established toxicity profile. Bevacizumab is an anti-VEGF monoclonal antibody with demonstrated activity in CNS tumors.

Our previous review of historical outcomes at our institution revealed suboptimal disease control and a high incidence of grade ≥3 toxic effects in patients treated before 2006. The purpose of this study was to evaluate changes during the past decade since the introduction of proton therapy.
View Article and Find Full Text PDFPurpose: In 2010, we published a comprehensive review of our institutional outcomes about treating children with spinal and paraspinal Ewing sarcoma using photon therapy. Multimodality therapy was associated with fair disease control but also with serious toxicity, including a 37% rate of grade 3 or greater toxicity. We therefore sought to assess our more recent experience about treating children with more modern technology and treatment regimens.

Proton therapy may improve the therapeutic ratio in these patients. We report outcomes in infants with rhabdomyosarcoma treated with proton therapy.

Purpose: Ewing sarcoma of the pelvis is associated with inferior local control compared with those arising from other primary sites. Despite its increased use, outcome data for treatment with proton therapy remain limited. We report 3-year disease control and toxicity in pediatric patients treated with proton therapy.

This report documents our experience with another manifestation: a primitive sarcoma that resembles PPB and DICER1-associated sarcoma of the kidney. These tumors are distinguished by their unusual location in the peritoneal cavity, associated with visceral and/or parietal mesothelium.

Purpose: This study aimed to report on the institutional outcomes after proton therapy for pelvic rhabdomyosarcoma (RMS).
Methods And Materials: Thirty-one children (≤21 years old) with group III pelvic RMS were enrolled on a prospective outcome study and treated between 2007 and 2018. Patients with vaginal/cervical RMS were excluded.
Purpose: Despite the dosimetric advantages of proton therapy, little data exist on patients who receive proton therapy for Ewing sarcoma of the cranium and skull base. This study reports local disease control and toxicity in such patients.
Materials/methods: We reviewed 25 patients (≤21 years old) with nonmetastatic Ewing sarcoma of the cranium and skull base treated between 2008 and 2018.
Posaconazole is a lipophilic triazole antifungal that exhibits variable absorption when administered orally. It possesses a broad spectrum of activity against various fungi, such as Aspergillus and traditionally resistant molds such as Rhizopus and Mucor, which carry a poor prognosis. Unfortunately, the tablet and suspension formulations of posaconazole are Food and Drug Administration approved for treatment of fungal diseases only in patients older than 13 years of age.

We therefore evaluated outcomes in our pediatric patients who received 45 GyRBE using proton therapy. To assess disease control and toxicity, we reviewed the medical records of 30 children (≤21 years old) with COG stage 1, group III embryonal orbital rhabdomyosarcoma enrolled on a prospective outcome study and treated with proton therapy between 2007 and 2018.

Treatment-related acute esophagitis can lead to hospitalization and treatment delays. The aim of this study was to analyze the incidence, risk factors, and management of esophagitis in pediatric patients with Ewing sarcoma of the thoracic region.

Pediatric lung cancer is a very rare occurrence, particularly as a primary lesion. A concurrent diagnosis is even more unusual and only reported a handful of times in Ewing sarcoma. Our patient is a 13-year-old boy who had concurrent diagnoses of Ewing sarcoma and minimally invasive adenocarcinoma of the lung, formerly bronchoalveolar carcinoma.

The study here grew sweet potato (Ipomoea batatas) to maturity in field microcosms using substrate amended with three concentrations (100, 500 or 1000 mg kg DW) of either nZnO, nCuO, or nCeO or equivalent amounts of Zn, Cu, or Ce. Adverse effects on tuber biomass were observed only for the highest concentration of Zn or Cu applied.

In a prior study, the accumulation of Zn, Cu, and Ce from ZnO, CuO, or CeO2, respectively, was examined in carrot (Daucus carota L.) grown in sand culture in comparison to accumulation from exposure to equivalent concentrations of ionic Zn(2+), Cu(2+), or Ce(4+).

Procedure: We performed a randomized, placebo-controlled, double-blind trial of oral glutamic acid as a preventive agent in pediatric patients with cancer who would be receiving vincristine therapy for at least 9 consecutive weeks (Stratum 1 = Wilms tumor and rhabdomyosarcoma) or 4 consecutive weeks in conjunction with steroids (Stratum 2 = Acute lymphoblastic leukemia and non-Hodgkin lymphoma).
Voriconazole pharmacokinetics are not well characterized in children despite prior studies. To assess the appropriate pediatric dosing, a study was conducted in 40 immunocompromised children aged 2 to <12 years to evaluate the pharmacokinetics and safety of voriconazole following intravenous (IV)-to-oral (PO) switch regimens based on a previous population pharmacokinetic modeling: 7 mg/kg IV every 12 h (q12h) and 200 mg PO q12h. Area under the curve over the 12-h dosing interval (AUC(0-12)) was calculated using the noncompartmental method and compared to that for adults receiving approved dosing regimens (6 → 4 mg/kg IV q12h, 200 mg PO q12h).

Procedure: Patients with Ewing sarcoma family of tumors (ESFT), osteosarcoma (OS), soft tissue sarcomas (STS), medulloblastoma (MB)/primitive neuroectodermal tumor (PNET), astrocytoma, or neuroblastoma (NB) recurrent or refractory to conventional therapy, measurable disease, and adequate organ function were treated with topotecan 0.3 mg/m2/day by continuous intravenous infusion for 21 consecutive days, followed by 7 days without therapy prior to response assessment.
Background: The optimal administration of radiotherapy for patients with high-risk neuroblastoma (NB) currently is undefined in the context of modern therapy using myeloablative chemotherapy with autologous stem cell rescue (hematopoietic stem cell transplantation [HSCT]).
Methods: The authors conducted a retrospective review of the records of 21 consecutive patients with high-risk NB to assess local control and toxicity of external beam radiotherapy (XRT). Therapy included multiagent induction chemotherapy and delayed surgical resection, consolidation of HSCT and local XRT, and 13-cis-retinoic acid maintenance therapy.
