Retrospective experience of children with relapsed brain tumors treated with oral combination of axitinib and metronomic etoposide.

Metronomic chemotherapy-based combinations have received interest for relapsed/refractory malignancies. Preclinical and clinical studies showed activity of metronomic etoposide and axitinib. We report our retrospective experience in six children treated with axitinib and metronomic etoposide for refractory/relapsed brain tumors as an "off-label" combination.

Late toxicity comparison of alkylating-based maintenance regimen with cyclophosphamide (VAC) vs ifosfamide (VAI) in Ewing sarcoma survivors treated in the randomized clinical trial Euro-EWING99-R1 in France.

In Euro-EWING99-R1 randomized trial, cyclophosphamide was shown to be noninferior to ifosfamide in the consolidation of standard-risk Ewing sarcoma (SR-EWS) after a common induction with VIDE (vincristine-ifosfamide-doxorubicin-etoposide). We present the results of the late effects analysis of VAC (vincristine-dactinomycin-cyclophoshamide) vs VAI (vincristine-dactinomycin-ifosfamide) conducted in Euro-EWING99-R1 French cohort. Of 267 French randomized patients, 204 were alive and free-of-relapse at 5-years including 172 with available long-term follow-up data concerning cardiac, renal and/or gonadal functions (sex-ratio M/F = 1.

AGAP3: A novel BRAF fusion partner in pediatric pancreatic-type acinar cell carcinoma.

Most available molecular data on pancreatic acinar cell carcinoma (PACC) are provided by studies of adult cases. BRAF, RAF1, or RET rearrangements have been described in approximately 30% of cases. To the best of our knowledge, only seven cases with molecular data have been reported in pediatric PACC.

Tolerance induction to deferasirox in a child with transfusion-dependent beta thalassemia.

Beta thalassemias are autosomal recessive hemoglobin disorders related to a defect in the beta-globin chain production. Most of the major forms of beta-thalassemia are transfusion dependent leading to iron overload. Today, three iron chelators are available in France.

Rhabdomyosarcoma associated with germline TP53 alteration in children and adolescents: The French experience.

Objective: To describe the clinical characteristics and outcome of patients with Li-Fraumeni-associated rhabdomyosarcoma (RMS).

Method: Retrospective analysis of data from 31 French patients with RMS diagnosed before the age of 20 years associated with a TP53 pathogenic germline variant. Cases were identified through the French Li-Fraumeni database.

Tumor rupture in hepatoblastoma: A high risk factor?

Background: Hepatoblastoma tumor rupture is a high-risk criterion in the SIOPEL 3/4 protocol. Little is known about the outcome of these children.

Methods: Radiological signs of possible tumor rupture, defined as peritoneal effusion, peritoneal nodules, or hepatic subcapsular hematoma, were reported in 24 of 150 patients treated for hepatoblastoma in France from January 2000 to December 2014 after central radiological expert review.
