Abstract:Intravenous immunoglobulin(IVIG) has been widely used in chemotherapy for hematological malignancies, targeted therapy, and hematopoietic stem cell transplantation;however, there are still no available guidelines or consensus statements on the application of IVIG in pediatric hematological/neoplastic diseases at present in China and overseas. This consensus is developed based on the research advances in the application of IVIG in pediatric hematological/neoplastic diseases across the world and provides detailed recommendations for the clinical application of IVIG in pediatric hematological/neoplastic diseases and the prevention and treatment of related adverse reactions.
