Glioma is a highly lethal malignancy and multiple challenges remain for it in the genomic study and clinical treatment. Next-generation sequencing (NGS) holds many advantages, and NGS can comprehensively analyze the whole genome, exome, transcriptome and epigenome to deepen the understanding of tumor genomics; and now, it has been successfully applied in the clinical study of some tumors, especially in personalized treatment for these tumors. At present, NGS has also been a hot in glioma research to clarify the pathogenesis of glioma, so as to draw up a personalized treatment method to benefit the patients.
