Demonstrates high diagnostic yields in pediatric brain tumors using minimal invasive techniques, suggesting improved patient outcomes.
Through the use of contemporary minimally invasive techniques, pediatric brain tumor biopsy has a histological diagnostic yield of 88.3% and molecular diagnostic yield of 82.0%. Robot-guided and optical image-guided techniques provided the highest diagnostic yield (97.5% and 91.4%, respectively, for histological analysis), while endoscopic biopsies had the highest rate of nondiagnostic results (19.2%), likely due to smaller specimen volumes.
