儿童急性淋巴细胞白血病的抗体和细胞疗法：机制与前景

BACKGROUND: Acute lymphoblastic leukemia (ALL) is one of the most commonly diagnosed cancers in children. Despite enormous efforts to treat ALL over the past decade, the intensity of conventional chemotherapeutic strategies has reached the tolerance limit. Among various recently developed therapeutic approaches, antibody and cellular-based therapies showed less toxicity and better curative effect. SUMMARY: Due to advanced mechanistic actions, these innovative therapies have provided durable responses and long-term survival in eradicating pediatric ALL, especially patients with refractory/relapsed ALL. Owing to these aspects, herein, we emphasize the mechanisms of action and application status of antibodies targeting tumor antigens, antibody-drug conjugates, bispecific antibodies, and chimeric antigen receptor T cells. KEY MESSAGES: The significant prospects and challenges are discussed, highlighting the innovative immunotherapies to deal with ALL. Together, this review will summarize the progress of antibody and cellular-based therapies for pediatric ALL, which may promote further research on antibody-based biopharmaceutics.
