Targeting CNS Metastases in Non-Small Cell Lung Cancer With Evolving Approaches Using Molecular Markers: A Review.

Importance: Central nervous system (CNS) metastases presenting as either brain parenchymal metastases or leptomeningeal metastases are diagnosed in up to 50% of patients with advanced non-small cell lung cancer during their disease course. While historically associated with a poor prognosis due to limited treatment options, the availability of an increasing number of targeted therapies with good CNS penetration has significantly improved clinical outcomes for these patients. This has occurred in parallel with a more nuanced understanding of prognostic factors.

Disrupting the epileptogenic network with stereoelectroencephalography-guided radiofrequency thermocoagulation.

Stereoelectroencephalography-guided radiofrequency thermocoagulation (SEEG-guided RF-TC) is a treatment option for focal drug-resistant epilepsy. In previous studies, this technique has shown seizure reduction by ≥50% in 50% of patients at 1 year. However, the relationship between the location of the ablation within the epileptogenic network and clinical outcomes remains poorly understood.

Statistical segmentation model for accurate electrode positioning in Parkinson's deep brain stimulation based on clinical low-resolution image data and electrophysiology.

Background: Deep Brain Stimulation (DBS), applying chronic electrical stimulation of subcortical structures, is a clinical intervention applied in major neurologic disorders. In order to achieve a good clinical effect, accurate electrode placement is necessary. The primary localisation is typically based on presurgical MRI imaging, often followed by intra-operative electrophysiology recording to increase the accuracy and to compensate for brain shift, especially in cases where the surgical target is small, and there is low contrast: e.
