Optimal timing in the treatment of intracranial hemangioblastoma (HB) remains controversial, particularly for patients of von Hippel-Lindau disease (VHL) with multiple small lesions. We evaluated efficacy of stereotactic radiosurgery (SRS) for intracranial HB based on the longer follow-up data with a larger number of patients and lesions. ⋯ SRS could be offered as an effective treatment for small, solid, and VHL-associated HBs. If the tumors show apparent enlargement in size or can possibly become symptomatic along with a slight increase in size, SRS should be recommended before they present with the clinical symptoms.

Diffuse low-grade gliomas (LGGs) form a heterogeneous subgroup of gliomas in adults. Chromosome (chr) arms 1p/19q codeletion and IDH mutation have been shown to be closely associated with oligodendroglial phenotype and better prognosis. We sought to identify relevant biomarkers in non 1p/19q codeleted LGGs. ⋯ Novel genomic entities and biomarkers have been identified in non 1p/19q codeleted LGGs. Our findings may help to stratify non 1p/19q codeleted LGGs, facilitating future individualization of treatment. Further prospective studies are warranted to support our findings.
