COVD-28. IMPACT OF COVID‐19 IN CHILDHOOD CENTRAL NERVOUS SYSTEM TUMORS IN ARGENTINA. REPORT FROM THE NATIONAL PEDIATRIC CANCER REGISTRY, ROHA NETWORK

Introduction: The true impact of COVID‐19 infection on children undergoing cancer treatment is unknown. At the present time, data on the clinical spectrum and outcome of children with cancer and concurrent COVID‐19 are limited, and further data are awaited. Monitor the incidence and survival across this pandemic is critical to understanding the extent to which this occur and to prepare contingency plans. Results: Ninety-seven pediatric patients with cancer and COVID-19 infection have been identified by the Argentinian Oncopediatric Register since April 2020. Sixteen of them had diagnosis of CNS tumor (female=7, male=9); 5 Medulloblastoma, 3 DIPG, 2 GBM, 2 LGG, 2 anaplastic ependymoma, 1 anaplastic ganglioglioma and 1 germinoma. Most frequent aged was between 1–4 years old (6 patients), followed by 15 to 19 (4p), 5–9 (3p) and 10–14 (3p). Most patients were asymptomatic (9p) and the screening was performed regarding a virus exposed (5p), previous to a procedure with anesthesia (2p) and previous a mandatory travel (2p). The most frequent symptom was isolated fever (6p); only 1 patient presented fever with others symptoms. None received specific treatment for COVID infection. No death related to COVID-19 infection was found; 1 patient with metastatic medulloblastoma and COVID-19 infection passed away due to a rapidly tumor progression. Conclusion: Although COVID-19 infection is a new challenging in the management of pediatric brain tumor patients, our experience showed a relative indolent course in this specific population.
