Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, Volume 20, Issue 8, Page 2023-2039, August 2026.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Evaluation of dosimetric impact and plan robustness of MLC motion and setup errors in SRS for multiple brain metastases

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background HyperArc is an effective technique for treating multiple small brain metastases using high‐definition, precise radiation. However, the small size of individual lesions makes treatment vulnerable to inherent inaccuracies from beam‐limiting devices such as multi‐leaf collimators (MLCs), as well as patient setup errors.

Accelerated and standardized commissioning of a robotic RadioSurgery system using a hybrid golden beam data model

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The CyberKnife™ system requires extensive beam data acquisition across multiple collimation systems. The CyberComm™ framework integrates a linac output tuning procedure with a hybrid Golden Beam Data (GBD) model to accelerate and standardize CyberKnife commissioning while maintaining dosimetric accuracy.

Human Epidermal Growth Factor Receptor 2‐Positive, Claudin‐18 Isoform 2‐Positive, Mismatch Repair‐Deficient Gastric Cancer Revealed by Immunohistochemical Analysis of Surgical Specimens: A Case Report

Cancer Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Human epidermal growth factor receptor 2 (HER2), mismatch repair (MMR) proteins, claudin‐18 isoform 2 (CLDN18.2), and the programmed cell death ligand‐1 combined positive score (PD‐L1 CPS) are predictive biomarkers for the efficacy of combination chemotherapy in patients with locally advanced unresectable or metastatic gastric or ...
