A 46-year-old man was diagnosed with brain metastasis after a two-year history of melanoma. Paliative radiotherapy was administered followed by dacarbazine, temozolamide, ipilimumab, stereotactic radiosurgery, ipilimumab reinduction and finally vemurafenib, to which the patient showed objective responses. The patient received vemurafenib for four months and died after progresive disease. Long-term follow-ups after surgery have been reported in the literature. However, in patients with unresectable metastases, outcomes are mostly detrimental. The present patient survived for 40 months after brain metastasis. The unusually long survival observed in the present case indicates the sequential effectiveness of radiotherapy, chemotherapy, ipilimumab, stereotactic radiosurgery and vemurafenib.

Glioblastoma multiforme (GBM) is characterized by pronounced immune escape and resistance to chemotherapy-induced apoptosis. Preliminary investigations revealed a marked overexpression of gasdermin E (GSDME) in GBM. Notably, cisplatin (CDDP) demonstrated a capacity of inducing pyroptosis by activating caspase-3 to cleave GSDME, coupled with the release of proinflammatory factors, indicating the potential as a viable approach of inducing anti-tumor immune activation.

Recent technologic advancements have facilitated the use of hypofractionated Gamma Knife-based radiosurgery (HF-GKRS) to treat large lesions or those in eloquent areas. This study aimed to analyze the preliminary results of HF-GKRS for these meningiomas, and to determine its effectiveness and safety. This single-center retrospective study analyzed data of patients who underwent HF-GKRS for large meningiomas or those in eloquent areas with > 6 months of follow-up.

Glioblastoma multiforme (GBM) is the most prevalent, treatment-resistant, and fatal form of brain malignancy. It is characterized by genetic heterogeneity, and an infiltrative nature, and GBM treatment is highly challenging. Despite multimodal therapies, clinicians lack efficient prognostic and predictive markers.

Glioma is a highly fatal and heterogeneous brain tumor with few known risk factors. Our study examines genetically predicted variability in blood cell indices in relation to glioma risk and survival in 3418 cases and 8156 controls. We find that increased platelet to lymphocyte ratio (PLR) confers an increased risk of glioma (odds ratio (OR) = 1.

The etiological basis of pituitary neuroendocrine tumors is uncertain. We used Mendelian randomization technique to investigate the potential influence of several risk factors on the likelihood of developing pituitary neuroendocrine tumors. We admitted 8 risk factors, divided into 3 lifestyle factors and 5 chronic diseases as exposure factors.
