Appendiceal neuroendocrine tumors in children and adolescents: The European Cooperative Study Group for Pediatric Rare Tumors (EXPeRT) diagnostic and therapeutic recommendations.

Neuroendocrine tumors of the appendix, formerly known as carcinoid tumors, represent a rare entity. They are slow-growing tumors, characterized by an indolent clinical course. In pediatric patients, the 5-year overall survival is estimated to be 100% and the event-free survival slightly less than 100%, with only one reported case of local relapse to date.

Impact of maintenance treatment on male gonadal function in patients treated for localized rhabdomyosarcoma in RMS2005 trial in France.

Background: Maintenance treatment with vinorelbine and oral cyclophosphamide (oral-CPM) improves outcome of nonmetastatic high-risk (HR) and very-high risk (VHR) rhabdomyosarcoma (RMS) patients. However, gonadal toxicity of maintenance was not yet investigated.

Methods: The authors focused their analysis on male gonadal toxicity in HR/VHR groups of RMS2005 trial, in France.

Portal Vein Obstruction in Pediatric Liver Transplant Patients: An Evaluation of Self-Reported Management Practices.

Background And Aims: Portal vein obstruction (PVO) is a known complication after pediatric liver transplantation (pLT). Effective management strategies are crucial in improving patient outcomes. This study investigated the various practice patterns related to PVO management to clarify the degree of consensus on the diverse facets of care involved in addressing PVO after pLT.

Surgical Strategy for Pediatric Liver Tumors Involving the Hepatic Venous Confluence and the Inferior Vena Cava.

Background: Pediatric liver tumors presenting as centrally located masses with contact to or even invasion of all three hepatic veins (HVs) and the inferior vena cava (IVC) present significant surgical challenges. While liver transplantation may be indicated in truly unresectable tumors, extended liver resection with vascular reconstruction can be an organ-preserving alternative.

Objective: This study aimed to present a reference center's strategy for children with liver tumors involving the hepatic venous confluence or the retrohepatic IVC who underwent extended liver resection with vascular reconstruction.

Maintenance Chemotherapy in Patients With High-Risk Rhabdomyosarcoma: Long-Term Survival Analysis of the European Soft Tissue Sarcoma Study Group RMS 2005 Trial.

The European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) RMS 2005 trial evaluated maintenance chemotherapy in high-risk rhabdomyosarcoma (RMS). Patients were randomly assigned to either discontinue treatment (standard arm) or receive six 28-day cycles of vinorelbine (25 mg/m) once per day on days 1, 8, and 15, plus once daily low-dose cyclophosphamide (25 mg/m; experimental arm). Initial results showed improved overall survival (OS), but disease-free survival (DFS) improvement was not statistically significant.

Pulmonary Consequences of Surgical Treatment in Children's Primary Lung Tumors: A National Retrospective Study.

Background And Aims: Primary lung tumors (PLTs) in children are rare, and surgery remains the key to ensure remission. Here we describe the PLTs clinical characteristics, their management, and the pulmonary outcome following surgery.

Methods: We carried out a French national cohort of pediatric PLTs from 2013 to 2023 from the FRACTURE rare pediatric tumors national database.

Therapy and Outcomes of Patients with Relapsed Nonmetastatic Rhabdomyosarcoma: A Report from the French Society of Pediatric Oncology Malignant Mesenchymal Tumor Committee.

Background: The prognosis for patients with relapse of localized rhabdomyosarcoma (RMS) remains poor, with limited evidence for optimal second-line therapy. This study describes the management and outcomes of relapsed RMS patients in France.

Methods: We retrospectively reviewed all nonmetastatic RMS patients enrolled in France in the RMS 2005 study who relapsed between 2006 and 2019 after achieving complete local control, defined as complete remission or stable residue ≥ 6 months after treatment completion.

Too Big to Fail: Volumetric Analyses and Incidence of Posthepatectomy Liver Failure in 125 Major Hepatectomies in Children.

Objective: To assess the incidence of posthepatectomy liver failure (PHLF) and the role of the future liver remnant (FLR) in children undergoing major hepatectomy.

Background: Incidence and risk factors of PHLF in children are unclear, with no validated definition for this age group. Consequently, the role of the FLR in pediatric hepatectomy and evidence-based preoperative guidelines remains undefined.

Prediction of Whole Liver Graft Weight Based on Biometric Variables in Paediatric and Adult Liver Donors.

Background/objectives: In paediatric liver transplantation, donor-recipient compatibility depends on graft size. We explored whether the graft weight can be predicted using the donor's biometric parameters.

Methods: We used seven easily available biometric variables in 142 anonymised paediatric and adult donors, with data collected between 2016 and 2022.
