Multicenter StudyBilateral spheno-orbital meningiomas: surgical management, progression, and recurrence.
Bilateral spheno-orbital meningiomas (bSOMs) are a rare entity among meningiomas. These tumors are benign and predominantly affect women. They represent 4% of spheno-orbital meningiomas (SOMs) and are poorly described in the literature. This study aimed to describe the characteristics, risk factors, evolution, and management of bSOMs. ⋯ Bilateral SOMs are usually found in female patients and are strongly associated with hormone replacement therapy. Early surgical management with gross-total resection is the most effective treatment in terms of recurrence and improves visual acuity. Given the slow progressive nature of bSOMs and their time to recurrence, which can be up to 10 years, long-term follow-up of patients is essential.

Multicenter StudyLong-term radiographic and endocrinological outcomes of stereotactic radiosurgery for recurrent or residual nonfunctioning pituitary adenomas.
Stereotactic radiosurgery (SRS) is used for the treatment of residual/recurrent nonfunctional pituitary adenoma (NFPA). The aim of this study was to evaluate the factors related to long-term tumor control and delayed endocrinopathies following SRS. ⋯ SRS affords favorable and durable tumor control for the vast majority of NFPAs. Post-SRS hypopituitarism occurs in a minority of patients, but this risk increases with time and warrants long-term follow-up.

Multicenter StudyUse of circulating tumor cells and microemboli to predict diagnosis and prognosis in diffuse glioma.
Circulating tumor cell (CTC) detection is a promising noninvasive technique that can be used to diagnose cancer, monitor progression, and predict prognosis. In this study, the authors aimed to investigate the clinical utility of CTCs in the management of diffuse glioma. ⋯ The authors revealed a correlation between CTCs and clinical characteristics and demonstrated that CTCs and CTMs are independent predictors for the diagnosis and prognosis of diffuse glioma. Their CTC- and CTM-based survival models can enable clinicians to evaluate patients' response to surgery as well as their outcomes.

Industry payments to academic neurosurgeons in 2021: an open payments cross-sectional analysis.
The Open Payments Program (OPP) was a database started in 2013 by the US government to report payments made by the medical device and pharmaceutical industry to physicians. Neurosurgery is a technologically advanced field that relies heavily on the latest innovations for complex treatment of its patient population. This study sought to explore the financial relationship between academic neurosurgeons and the industry. ⋯ Neurosurgery has been rated by many as a field fueled by research, innovation, and technology. In 2021, academic neurosurgeons had a strong relationship with the medical device and pharmaceutical industry as reflected in the OPP data. While the true impact on patient care cannot be directly measured, the advancement of the field relies heavily on these collaborations.

Radiation therapy (RT) is used selectively for patients with low-grade glioma (LGG) given the concerns for potential cognitive effects in survivors, but prior cognitive outcome studies among LGG survivors have had inconsistent findings. Translational studies that characterize changes in brain anatomy and physiology after treatment of LGG may help to both contextualize cognitive findings and improve the overall understanding of radiation effects in normal brain tissue. This study aimed to investigate the hypothesis that patients with LGG who are treated with RT will experience greater brain volume loss than those who do not receive RT. ⋯ This study demonstrated volume loss in contralateral brain structures among LGG survivors, and patients who received RT experienced greater volume loss than those who did not. The results of this study may help to provide context for cognitive outcome research in LGG survivors and inform the design of future strategies to preserve cognition.
