Abstract
Objective: The development of novel targeted therapies is opening new perspectives in the treatment of pediatric brain tumors. Their precise role in therapeutic protocols still needs still to be defined. Thus, these novel pharmacological approaches in pediatric neurosurgery were the topic of the European Society for Pediatric Neurosurgery (ESPN) Consensus Conference held in Lyon (France) in January 25-27, 2024.
Method: The paper reviews the current knowledge about targeted therapy as well as the current literature published on the topic. The conference aimed for an interdisciplinary consensus debate among pediatric oncologists and pediatric neurosurgeons on the following questions. Question 1: What is the current role for targeted therapies as neoadjuvant treatments before pediatric brain tumor removal? Question 2: What are the benefits, cost/efficiency, and long-term side effects of targeted therapies in the treatment of pediatric brain tumors? Question 3: Based on contemporary data, at which stage and in which pathologies do targeted therapies play a significant role?
Results: Ninety-two participants answered consensus polls on the state of the art of targeted therapies, the ethical issues related to their use, and the evolving change in the role of pediatric neurosurgeons. The neoadjuvant role of targeted therapies is difficult to define as there are many different entities to consider. Despite the recently reported potential benefits, questions regarding the use of targeted therapies are manifold, in particular regarding sustainable benefits and long-term side effects. Additionally, challenging cost issues is a limiting factor for the broader availability of these drugs. Studies have demonstrated superiority of targeted therapy compared to chemotherapy both in randomized trials and compared to historical cohorts in the management of a subset of low-grade gliomas. The same drug combinations, BRAFi and MEKi, may be effective in HGG that have relapsed, progressed, or failed to respond to first-line therapy. Similar conclusions on efficacy may be drawn for mTORi in TSC and selumetinib in plexiform neurofibromas. For other tumors, the picture is still obscure due to the lack of data or even the lack of suitable targets. In conclusion, targeted treatment may not always be the best option even when a target has been identified. Safe surgery remains to be a favorable option in the majority of cases.
Conclusion: The constantly evolving drug technology and the absence of long-term safety and efficacy studies made it difficult to reach a consensus on the predefined questions. However, a report of the conference is summarizing the present debate and it might serve as a guideline for future perspectives and ongoing research.
期刊介绍：
The journal has been expanded to encompass all aspects of pediatric neurosciences concerning the developmental and acquired abnormalities of the nervous system and its coverings, functional disorders, epilepsy, spasticity, basic and clinical neuro-oncology, rehabilitation and trauma. Global pediatric neurosurgery is an additional field of interest that will be considered for publication in the journal.
