Allogeneic hematopoietic stem cell transplantation is challenging for patients with transfusion-dependent thalassemia who have experienced iron overload and received chronic transfusion support. A transplantation strategy including a reduced-intensity preparative regimen and tailored immunosuppression to support donor engraftment and prevent graft-versus-host disease (GVHD) was developed for this population. The combination of a pretransplantation immunosuppression phase with reduced dosing of fludarabine/prednisone, a treosulfan-based preparative regimen with reduced cyclophosphamide dosing, and introduction of a calcineurin/methotrexate-free GVHD prophylaxis/engraftment supporting regimen with abatacept/sirolimus/antithymocyte globulin was tested.

Background: Oculofaciocardiodental (OFCD) syndrome is an X-linked dominant condition that is typically lethal in males.

Observations: A 13-month-old male patient with OFCD syndrome presented with hepatoblastoma. He received chemotherapy per standard of care and had a surgical resection with few complications.

Background: Supportive care clinical practice guidelines (CPGs) facilitate the incorporation of the best available evidence into pediatric cancer care. We aimed to assess the impact of the work of the Children's Oncology Group (COG) Supportive Care Guideline Task Force on institutional supportive care practices.

Procedure: An online survey was distributed to representatives at 209 COG sites to assess the awareness, use, and helpfulness of COG-endorsed supportive care CPGs.

Purpose: The Pediatric Oncology Group of Ontario (POGO) supported an effort to implement infection management care pathways based on clinical practice guidelines, to improve the consistency of infection management in pediatric cancer patients. The objective of this qualitative study was to describe the perspective of healthcare professionals (HCPs) following implementation.

Methods: Four tertiary pediatric oncology centers in Ontario, Canada, implemented the pathways.

Objective was to update a clinical practice guideline (CPG) for the management of fatigue in children and adolescents with cancer or pediatric hematopoietic cell transplant recipients. We reconvened a multi-disciplinary and multi-national panel. While the previous 2018 CPG evaluated adult and pediatric randomized controlled trials (RCTs) to manage fatigue, this 2023 update revised previous recommendations based only on pediatric RCTs.

Article Synopsis
  • Genetic variations affecting the enzyme thiopurine methyltransferase (TPMT) can increase toxicity risk, especially in patients with TPMT deficiency, leading to higher TGN exposure.
  • A study of 88 pediatric patients found that those with intermediate TPMT activity faced significantly more febrile neutropenia and myelotoxicity compared to those with normal activity, suggesting the need for adjusted dosing based on genetic status to lower toxicity risks.

Waldeyer's ring (WR) involvement in pediatric Hodgkin lymphoma (HL) is extremely rare and criteria for determining involvement and response to treatment are unclear. The international Staging, Evaluation, and Response Criteria Harmonization for Childhood, Adolescent and Young Adult Hodgkin Lymphoma (SEARCH for CAYAHL) Group performed a systematic review of the literature in search of involvement or response criteria, or evidence to support specific criteria. Only 166 cases of HL with WR involvement were reported in the literature, 7 of which were pediatric.

Terms used to label types of clinical recommendations and guidance are applied inconsistently and do not reflect the methods used to create each type. Here, the international Pediatric Oncology Supportive Care Guideline Network proposes a lexicon for types of recommendations and guidance documents. A lexicon describing three types of recommendations (clinical practice guideline-derived, good practice statement, and expert opinion statement) and two types of guidance documents (clinical practice guideline and expert opinion) is presented.

Providing evidence-based supportive care for children with cancer has the potential to optimize treatment outcomes and improve quality of life. The Children's Oncology Group (COG) Supportive Care Guidelines Subcommittee conducted a systematic review to identify current supportive care clinical practice guidelines (CPGs) relevant to childhood cancer or pediatric hematopoietic stem cell transplant. Only 22 papers met the 2011 Institute of Medicine criteria to be considered a CPG.
