For many years, the treatment of pediatric lymphoma has been challenged by marked variability in therapeutic response and poor outcomes in relapsed or refractory cases. Under the leadership of Professor Zhang Yonghong, his team has driven the development of standardized and precision-based treatment strategies through long-term research and clinical innovation. In particular, they have achieved major breakthroughs in the management of relapsed and refractory pediatric lymphoma. By integrating molecular biology–based risk stratification and pioneering the application of CAR-T therapy, the team has significantly improved treatment outcomes, elevating the overall standard of pediatric lymphoma care in China. In this issue, Hematology Frontier invited Professor Zhang Yonghong to share insights into his team’s exploration and innovation in precision diagnosis and treatment of pediatric lymphoma, as well as his perspectives on future directions.
