Article Abstract
Among central nervous system (CNS) tumors, gliomas are the most prevalent type of tumor. Single nucleotide polymorphisms (SNPs) in telomerase reverse transcriptase (TERT) gene have been identified as risk loci for gliomas by previous genome-wide association studies (GWAS). We examined association between TERT variants and glioma risk in a Korean population. For a case-control study, a total of 32 TERT SNPs from 317 patients with glioma and 480 population-based controls were genotyped. Logistic regression was used for statistical analysis of the link between TERT SNPs and risk of glioma. In this study, eight TERT variants, including four glioma-associated variants reported in previous studies, showed significant association with the risk of glioma. Conditional and stepwise analyses were conducted to validate independent associations in the group of the eight variants. Both analyses identified an intronic variant (rs56345976) as the causal variant among the eight variants. Glioma subgroup analyses indicate that rs56345976 variant is associated with the risk of WHO grade 4, glioblastoma, isocitrate dehydrogenase (IDH) wild-type, and 1p/19q non-codeletion glioma. This study presents a profound comprehension of the relationship between TERT variants and the risk of glioma. Further studies of this variant are required to investigate its effect on glioma susceptibility.

Germline rare variants in cancer susceptibility genes and subsequent neoplasm risk after childhood cancer.
J Natl Cancer Inst

Background: Among childhood cancer survivors, germline rare variants in autosomal dominant cancer susceptibility genes (AD CSGs) could increase subsequent neoplasm (SNs) risks, but risks for rarer SNs and by age at onset are not well understood.
Methods: We pooled the Childhood Cancer Survivor Study and St Jude Lifetime Cohort (median follow-up = 29.7 years, range 7.
Role of patient frailty in resection of newly diagnosed motor eloquent glioblastomas guided by a navigated transcranial magnetic stimulation and tractography approach.

Department of Neurosurgery, Paracelsus Medical University, Breslauer Straße 201, 90471, Nuremberg, Bavaria, Germany.
Purpose: Resection of glioblastomas infiltrating the motor cortex and corticospinal tract (CST) is often linked to increased perioperative morbidity. Navigated transcranial magnetic stimulation (nTMS) motor mapping has been advocated to increase patient safety in these cases. The additional impact of patient frailty on overall outcome after resection of cases with increased risk for postoperative motor deficits as identified with nTMS needs to be investigated.

Background: Glioblastoma (GBM) is an extremely aggressive brain tumor, marked by restricted therapeutic possibilities and a generally unfavorable prognosis. GBM's complexity and heterogeneity necessitate comprehensive genetic and immunological profiling to enhance therapeutic strategies.
Methods: The study integrated The Cancer Genome Atlas (TCGA) and Integrative Epidemiology Unit Open Genome-Wide Association Studies (IEU OpenGWAS) data to identify genetic factors influencing GBM using expression quantitative trait loci (eQTL) and genome-wide association studies (GWAS).

Fludioxonil, a fungicide commonly used in agriculture, has been detected in livestock, such as cattle, even though it is primarily intended for use in plants. Unintended exposure to fludioxonil may compromise immune cells, cardiomyocytes, and glioma cells, indicating its potential risk as an environmental hazard. However, research on the detrimental effects of fludioxonil remains scarce, particularly regarding its impact on livestock, which are directly exposed to fludioxonil because of its widespread agricultural use.
