Variations in screening and management practices for subsequent asymptomatic meningiomas in childhood, adolescent and young adult cancer survivors.
Childhood, adolescent and young adult (CAYA) cancer survivors treated with cranial radiotherapy are at risk for developing subsequent meningiomas. There is insufficient evidence concerning the benefits and harms of screening for subsequent meningiomas, and uncertainty about the most appropriate clinical management of asymptomatic meningiomas. Data describing current clinical decision-making is essential to formulate surveillance recommendations. ⋯ There is international variation in opinions and clinical practice regarding screening for subsequent asymptomatic meningiomas among at risk CAYA cancer survivors. Decision-making regarding interventions of asymptomatic meningiomas are largely driven by clinical characteristics. These valuable insights into current clinical practice will inform surveillance guidelines for CAYA cancer survivors.

Congenital glioblastomas (cGBMs) are uncommon tumors presenting in early infancy, variably defined as diagnosed at birth or at age less than 3 months by strict criteria, or more loosely, as occurring in very young children less than 12 months of age. Previous studies have shown that cGBMs are histologically indistinguishable from GBMs in older children or adults, but may have a more favorable clinical outcome, suggesting biological differences between congenital versus other GBMs. Due to the infrequency of cGBMs, especially when employing strict inclusion criteria, molecular features have not been sufficiently explored. ⋯ Our results show that cGBMs are genetically heterogeneous and biologically different from pediatric and adult GBMs. Identification of ALK and ROS1 raise the possibility of targeted therapy with FDA-approved targeted inhibitors.

Evidence supporting routine postoperative antiepileptic drug (AED) prophylaxis following oncologic neurosurgery is limited, and actual practice patterns are largely unknown beyond survey data. ⋯ Use of seizure prophylaxis following intracranial biopsies and supratentorial resections is highly variable, consistent with a lack of guidelines or consensus. Current practice patterns do not support a clear standard of care and may be driven in part by geographic variation, availability of post-discharge services, and electronic prescribing defaults rather than evidence. Given uncertainty regarding effectiveness, indications, and appropriate duration of AED prophylaxis, well-powered trials are needed.

Socioeconomic factors affect treatment delivery for patients with low grade glioma: a Swedish population-based study.
Despite aspirations to achieve equality in healthcare we know that socioeconomic differences exist and may affect treatment and patient outcome, also in serious diseases such as cancer. We investigated disparities in neurosurgical care and outcome for patients with low-grade glioma (LGG). ⋯ The neurosurgical care for LGG in Sweden, a society with universal healthcare, displays differences that can be related to socioeconomic factors.

The combination of stereotactic radiosurgery with immune checkpoint inhibition or targeted therapy in melanoma patients with brain metastases: a retrospective study.
Evidence pointing to a synergistic effect of stereotactic radiosurgery (SRS) with concurrent immunotherapy or targeted therapy in patients with melanoma brain metastases (BM) is increasing. We aimed to analyze the effect on overall survival (OS) of immune checkpoint inhibitors (ICI) or BRAF/MEK inhibitors initiated during the 9 weeks before or after SRS. We also evaluated the prognostic value of patients' and disease characteristics as predictors of OS in patients treated with SRS. ⋯ The concurrent administration of anti-PD-1+/-CTLA-4 mAbs with SRS was associated with improved survival in melanoma patients with newly diagnosed BM. In addition to CNS tumor burden, the extension of systemic disease retains its prognostic value in patients treated with SRS. Elevated serum LDH levels are predictors of poor outcome in these patients.
