Abstract
PURPOSE: To review and critique the current state of liquid biopsy in pHGG. MATERIALS AND METHODS: Published literature was reviewed for articles related to liquid biopsy in pediatric glioma and adult glioma with a focus on high-grade gliomas. RESULTS: This review discusses the current state of liquid biomarkers of pHGG and their potential applications for liquid biopsy development. CONCLUSIONS: While nascent, the progress toward identifying circulating analytes of pHGG primes the field of neuro-oncoogy for liquid biopsy development.
