Next-generation CAR immunotherapy for neuroblastoma: expanding the role of immune cell platforms.
TL;DR
An overview of current therapeutic strategies for NB patients is provided and recent advances in the development of next-generation NB immunotherapies are summarized, highlighting their potential to improve NB management.
Abstract
Neuroblastoma (NB) is a pediatric cancer that develops from immature nerve cells in the peripheral sympathetic nervous system. NB is remarkably heterogeneous, ranging from spontaneous regression to aggressive progression, and is characterized by widespread dissemination and relapse. Approximately half of all NB patients present with widespread metastasis at diagnosis and are classified as high-risk with a substantial likelihood of treatment failure, despite receiving aggressive multimodal therapies, including surgery, chemotherapy, radiotherapy, autologous hematopoietic stem cell transplantation, and monoclonal antibody treatment. Beyond conventional multimodal approaches, immunotherapy has emerged as an essential part of cancer treatment, by boosting the immune system to recognize and eliminate tumor cells. In this review, we provide an overview of current therapeutic strategies for NB patients and summarize recent advances in the development of next-generation NB immunotherapies, highlighting their potential to improve NB management. We further discuss future directions for therapeutic improvement, and the potential limitations and challenges associated with translating these approaches into long-term benefits for NB patients.
