It is sometimes difficult to apply the headframes of stereotactic systems in awake patients who are lethargic or demented or in patients who are very sensitive to the discomfort of local anesthetic injection. A device for external stabilization of the stereotactic system during its application to the head is described. This device, a modification of the Somi brace, is easy to apply, allows for adjustment of the base ring in all planes and provides sufficient stability even in obtunded or uncooperative patients. This device simplifies and makes more precise the application of the stereotactic headframe and may be of considerable utility in stereotactic surgery.

Purpose: Especially in Europe, amino acid PET is increasingly integrated into multidisciplinary neuro-oncological tumor boards (MNTBs) to overcome diagnostic uncertainties such as treatment-related changes. We evaluated the accuracy of MNTB decisions that included the O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) PET information compared with FET PET results alone to differentiate tumor relapse from treatment-related changes.
Patients And Methods: In a single academic center, we retrospectively evaluated 180 MNTB decisions of 151 patients with CNS WHO grade 3 or 4 gliomas (n = 122) or brain metastases (n = 29) presenting equivocal MRI findings following anticancer treatment.
Expansion of stereotactic work envelope using transformation matrices and geometric algebra for neurosurgery.

Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.

Objective: To identify clinicopathologic and genomic features associated with brain metastasis after resection of lung adenocarcinoma (LUAD) and to evaluate survival after brain metastasis.
Methods: Patients who underwent complete resection of stage I-IIIA LUAD between 2011 and 2020 were included. A subset of patients had broad-based panel next-generation sequencing performed on their tumors.
Challenges in assessing national radiotherapy costs: application of the ESTRO-HERO model in Spain.

January 2025
Bellvitge Biomedical Research Institute (IDIBELL), Hospitalet Barcelona, Barcelona, Spain.
Background And Purpose: The aim was to estimate the cost of the external beam radiotherapy (EBRT) in public health care centers in Catalonia (Spain), according to the ESTRO-HERO costing model for 2018.
Materials And Methods: Personnel, equipment, and activity data from 2018 from the 11 RT centers were used, incorporating European mean values adapted to the Catalan context. Secondly, EBRT costs were estimated, incorporating 2023 fractionation technique and scheme usage percentages.
