Abstract

Simple Summary: In brain tumor surgery, increasing the extent of resection has been shown to improve patient outcomes and survival. 5-ALA serves as a tumor visualization adjunct and has been approved for use in adult high-grade gliomas. The purpose of this systematic review was to assess whether 5-ALA has similar utility and safety in pediatric patients. A total of 249 pediatric cases were identified from the relevant literature, confirming the safety of 5-ALA in this population. Overall, the fluorescence rates and utility were favorable, although there were some variations across different tumor grades and types. While our preliminary findings suggest that 5-ALA is both safe and effective in pediatric brain tumor surgery, further systematic clinical studies are needed to validate these results. Background: 5-Aminolevulinic acid-guided surgery for adult gliomas has been approved by the European Medicines Agency and the US Food and Drug Administration, becoming a reliable tool for improving gross total resection rates and patient outcomes. This has led several medical centers to explore the off-label use of 5-ALA in the resection of pediatric brain tumors, assessing its efficacy and safety across various tumor types. However, given the differences between children and adults, the appropriateness of 5-ALA use in pediatric populations has not yet been fully established. Methods: We collected eligible publications from Embase, Scopus, PubMed, and Proquest, ultimately selecting 27 studies. Data extraction and retrospective analysis of 249 surgical cases were conducted to determine the current efficacy and safety of 5-ALA in pediatric brain tumors. The fluorescence rate and utility stratified by several clinical features, including WHO grade, tumor classification, and tumor location, were analyzed. Results: Most studies suggest that 5-ALA can enhance tumor identification in high-grade tumors, including glioblastomas and anaplastic astrocytomas. Changes in survival or recurrence rates associated with 5-ALA-guided resection have not been reported. None of the cases reported significant postoperative complications related to the use of 5-ALA. Conclusions: 5-ALA can aid in the resection of high-grade gliomas in pediatric patients. The efficacy of 5-ALA in low-grade gliomas and other tumors may require enhancement with additional tools or modified administration protocols. The safety of 5-ALA has reached a preliminary consensus, although further randomized controlled trials and data on survival and molecular characteristics are needed. [ABSTRACT FROM AUTHOR]
