Objective: Glioma and meningioma are the most common primary brain tumors in adults. Epidemiologic studies of the relationship between female hormone exposure and exogenous hormone use and the risk of meningioma and glioma in females have yielded inconsistent results.
Methods: Two investigators comprehensively searched 3 electronic databases, including PubMed, Embase, and Cochrane Library. A total of 11 case-control studies were enrolled for meta-analysis. Dose-response meta-analyses were conducted.
Results: Compared with the non-oral contraceptives (OCs) female users, the female OC users might have reduced risk of glioma (risk ratio [RR], 0.87; 95% confidence interval [CI], 0.77-0.97; I = 42.6%). However, there was no obvious evidence of an association between OC use and the risk of meningioma in females (RR, 0.99; 95% CI, 0.87-1.13; I = 42.7%). Using OCs for >10 years in females may significantly decrease the risk of glioma to 30% (RR, 0.7; 95% CI, 0.6-0.81; I = 0%). The dose-response meta-analyses indicated that the risk of glioma in females significantly decreased when the duration of oral OC use was >7.5 years.
Conclusions: OC use may not increase the risks of glioma and meningioma in females. Instead, the long-term use of OCs may significantly decrease the risk of glioma, and the benefits are even more pronounced when the time window is >7.5 years. Nonetheless, the pooled results in this study suggest that OC use may not increase the risk of meningioma. Therefore, our conclusion should be validated and supplemented in future larger studies.

Department of Neurosurgery, The First Affiliated Hospital of Soochow University, Suzhou, China.
Purpose: This study aimed to identify prognostic factors and develop a nomogram for survival in patients with brainstem ependymoma.
Methods: Data of 652 patients diagnosed with brainstem ependymoma extracted from the Surveillance, Epidemiology, and End Results (SEER) registry from 2000 to 2020 were analyzed. Univariate and multivariable Cox regression analyses were performed to examine factors influencing overall survival (OS).

Objective: Communicating hydrocephalus (CH) is an uncommon complication that can affect patients with glioblastoma (GBM). Due to its clinical and radiological findings, it presents as a chronic hydrocephalus. The mechanisms underlying its occurrence and impact on the prognosis of the disease are poorly known, but some studies have suggested that shunting can have a positive impact on the quality of life of these patients.
View Article and Find Full Text PDFBrain cancer continues to be one of the most formidable malignancies to manage, mainly attributable to the presence of the blood-brain barrier (BBB) limiting the permeability of drugs and the diverse characteristics of brain tumors complicating treatment. The management of brain tumors has been hampered by many different factors, including the impermeability of the BBB, which restricts the delivery of chemotherapeutic agents to the tumor site, as well as intertumoral heterogeneity and the influence of brain tumor stem cells. In addition, small molecular weight drugs cannot specifically accumulate in malignant cells and have a limited circulation half-life.

Background: Within the realm of primary brain tumors, specifically glioblastoma (GBM), presents a notable obstacle due to their unfavorable prognosis and differing median survival rates contingent upon tumor grade and subtype. Despite a plethora of research connecting cardiotrophin-1 (CTF1) modifications to a range of illnesses, its correlation with glioma remains uncertain. This study investigated the clinical value of CTF1 in glioma and its potential as a biomarker of the disease.

Background: Glioblastoma multiforme (GBM) is a common and highly aggressive brain tumor with a poor prognosis. However, the prognostic value of ferroptosis-related genes (FRGs) and their classification remains insufficiently studied.
Objective: This study aims to explore the significance of ferroptosis classification and its risk model in GBM using multi-omics approaches and to evaluate its potential in prognostic assessment.
