Selection for proton radiotherapy of grade 1-3 glioma patients.

Background: For adult patients with grade 1-3 gliomas, identifying patients with an indication for proton therapy (PT) can be challenging due to sparse evidence supporting its benefits. In this study, we aimed to ensure national consensus and develop a decision support tool to aid clinicians in identifying patients with grade 1-3 gliomas eligible for PT.

Methods: Sixty-one historic patients referred for postoperative radiotherapy for glioma grade 1-3 were included in this study and had new photon therapy and PT plans calculated.

Treatment plan comparison of proton vs photon radiotherapy for lower-grade gliomas.

Background And Purpose: Patients with lower-grade gliomas are long-term survivors after radiotherapy and may benefit from the reduced dose to normal tissue achievable with proton therapy. Here, we aimed to quantify differences in dose to the uninvolved brain and contralateral hippocampus and compare the risk of radiation-induced secondary cancer for photon and proton plans for lower-grade glioma patients.

Materials And Methods: Twenty-three patients were included in this in-silico planning comparative study and had photon and proton plans calculated (50.

A national study on the inter-observer variability in the delineation of organs at risk in the brain.

Background: The Danish Neuro Oncology Group (DNOG) has established national consensus guidelines for the delineation of organs at risk (OAR) structures based on published literature. This study was conducted to finalise these guidelines and evaluate the inter-observer variability of the delineated OAR structures by expert observers.

Material And Methods: The DNOG delineation guidelines were formed by participants from all Danish centres that treat brain tumours with radiotherapy.

UWB Wind Turbine Blade Deflection Sensing for Wind Energy Cost Reduction.

A new application of utilizing ultra-wideband (UWB) technology to sense wind turbine blade deflections is introduced in this paper for wind energy cost reduction. The lower UWB band of 3.1-5.
