RESUMO
The study analyzes the current status of personalized medicine in pediatric oncology in Spain. It gathers national data on the tumor molecular studies and genomic sequencing carried out at diagnosis and at relapse, the centers that perform these studies, the technology used and the interpretation and clinical applicability of the results. Current challenges and future directions to achieve a coordinated national personalized medicine strategy in pediatric oncology are also discussed. Next generation sequencing-based (NGS) gene panels are the technology used in the majority of centers and financial limitations are the main reason for not incorporating these studies into routine care. Nowadays, the application of precision medicine in pediatric oncology is a reality in a great number of Spanish centers. However, its implementation is uneven and lacks standardization of protocols; therefore, national coordination to overcome the inequalities is required. Collaborative work within the Personalized Medicine Group of SEHOP is an adequate framework for encouraging a step forward in the effort to move precision medicine into the national healthcare system.

PURPOSE: The COVID-19 pandemic has forced healthcare stakeholders towards challenging decisions. We analyse the impact of the pandemic on the conduct of phase I-II trials for paediatric cancer during the first month of state of alarm in Spain. METHODS: A questionnaire was sent to all five ITCC-accredited Spanish Paediatric Oncology Early Phase Clinical Trial Units, including questions about impact on staff activities, recruitment, patient care, supply of investigational products, and legal aspects. RESULTS: All units suffered personnel shortages and difficulties in enrolling patients, treatment continuity, or performing trial assessments. Monitoring activity was frequently postponed (73%), and 49% of on-going trials interrupted recruitment. Only two patients could be recruited during this period (75% reduction in the expected rate). CONCLUSIONS: The COVID-19 crisis has significantly impacted clinical research practice and access to innovation for children with cancer. Structural and functional changes are under way to better cope with the expected future restrictions.

PURPOSE: Elevated mortality and morbidity rates persist in pediatric patients with medulloblastoma. We present a clinical audit of a real-world cohort of patients in search for pragmatic measures to improve their management and outcome. METHODS/PATIENTS: All pediatric patients with medulloblastoma treated between 2003 and 2016 at a Spanish reference center were reviewed. In the absence of internationally accepted quality indicators (QIs) for pediatric CNS tumors, diagnostic, therapeutic, survival, and time QIs were defined and assessed. RESULTS: Fifty-eight patients were included, 24% were younger children (< 3 years), 36% high risk (anaplastic, metastasis, or surgical residue > 1.5 cm2), and 40% standard risk. Five-year OS was 59.2% (95% CI 47-75); 5-year PFS 36.4% (95% CI 25-53). Five main areas of quality assurance were identified: diagnosis, global strategy, frontline treatment modalities, outcomes, and long-term and end-of-life care. A set of 34 QIs was developed and applied. Lack of central pathology review, delay in the incorporation of novel molecular markers, and absence of a neurocognitive and quality-of-life evaluation program were some of the audit findings. CONCLUSIONS: This real-world research study resulted in the development of a pragmatic set of QIs, aimed to improve clinical audits and quality of care given to children and adolescents with medulloblastoma. We hope that our findings will serve as a reference to further develop a quality assurance system with specific QIs for pediatric CNS tumors in the future and that this will ultimately improve the survival and quality of life of these patients.

PURPOSE: Corticoid-induced osteonecrosis (ON) of femoral head can lead to severe hip joint impairment and hip replacement, with negative impact in young survivors of acute lymphoblastic leukaemia (ALL) with long life expectancy. We aim to improve quality of life in these patients with a novel approach. METHODS/PATIENTS: Based on the regenerative capacities of mesenchymal stem cells (MSCs), we performed locally implanted autologous cell therapy in two adolescents suffering of bilateral femoral ON. This required a simple, minimally invasive surgical procedure. RESULTS: Both patients experienced significant pain relief and restoration of gait kinematic values. Radiographic evaluation showed cessation of hip collapse. No toxicities/complications were observed after a 4-year follow-up. CONCLUSIONS: Our preliminary results suggest that autologous MSCs can be considered as a novel treatment for children and young adults with ON after overcoming ALL. It may avoid hip replacement and improve quality of life of leukaemia survivors.

PURPOSE: Neuroendocrine tumors (NETs) are, after lymphomas, the most frequent gastrointestinal tumors in children, mainly located in the appendix. Best management remains unclear, given the absence of pediatric guidelines. We present the first Spanish series of pediatric patients with NETs. PATIENTS AND METHODS: Retrospective study of all pediatric patients (<18 years) with NET treated in four oncology reference institutions in Spain between 1994 and 2015. RESULTS: Seventeen patients were included. All patients presented with acute abdomen. TNM stage was T1a (82%) and T1b (12%). Extension study was heterogenous, with only 4 patients undergoing an OctreoScan. Four patients met criteria for second surgery (affected surgical margins or mesoappendix invasion), but it was only performed in two. Despite the diverse management, none of the patients relapsed during follow-up. CONCLUSIONS: The disparity in diagnostic tests, second surgery criteria and follow-up shown in this study highlights the need for specific pediatric guidelines.
