[Hospital Inpatient Use in Mainland Portugal by Children with Complex Chronic Conditions (2011 - 2015)].

Introduction: Due to epidemiological change, interest in complex chronic conditions has been increasing within the pediatric health system. As such, we aim to evaluate hospital inpatient care in the National Health Service (mainland Portugal) by pediatric patients (0 - 17 years) with complex chronic conditions.

Material And Methods: Observational longitudinal retrospective epidemiological study using anonymized administrative data.

Busulfan and melphalan versus carboplatin, etoposide, and melphalan as high-dose chemotherapy for high-risk neuroblastoma (HR-NBL1/SIOPEN): an international, randomised, multi-arm, open-label, phase 3 trial.

Background: High-dose chemotherapy with haemopoietic stem-cell rescue improves event-free survival in patients with high-risk neuroblastoma; however, which regimen has the greatest patient benefit has not been established. We aimed to assess event-free survival after high-dose chemotherapy with busulfan and melphalan compared with carboplatin, etoposide, and melphalan.

Methods: We did an international, randomised, multi-arm, open-label, phase 3 cooperative group clinical trial of patients with high-risk neuroblastoma at 128 institutions in 18 countries that included an open-label randomised arm in which high-dose chemotherapy regimens were compared.
