Resveratrol for Cancer Radio‐Sensitization: Ready for Prime Time or Future Perspective

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Resveratrol exerts antioxidant and anti‐inflammatory effects by reducing reactive oxygen species and suppressing NF‐κB and JAK/STAT signaling pathways. It modulates metabolic signaling through AMPK‐dependent inhibition of mTOR, influencing cell survival and inflammatory responses.

Disparities in Proton Radiation Utilization for HPV‐Associated Oropharyngeal Cancer Following TORS

Head &Neck, Volume 48, Issue 5, Page 1218-1224, May 2026.
ABSTRACT Introduction Racial, socioeconomic, and geographic disparities in receipt of proton radiation have been reported. Whether disparities exist for oropharyngeal squamous cell carcinoma (OPSCC) is not well studied. Methods Patients with HPV‐associated OPSCC treated with transoral robotic surgery (TORS) and adjuvant radiation from 2016 to 2023 were

A preclinical setup for spatially fractionated radiation therapy with electrons

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Spatially fractionated radiation therapy (SFRT) has therapeutic potential as a priming therapy which boosts tumor control. However, the optimal delivery and spatial fractionation parameters have not been deciphered and the mechanisms at play are not yet fully understood.

Retrospective Dosimetric Comparison of HDR Interventional Radiotherapy (Brachytherapy) Versus Planning with VMAT and Electron Beam Therapy for Non-Melanoma Skin Cancer Treatment

Applied Sciences
This study compares dosimetric outcomes of high-dose-rate (HDR) interventional radiotherapy (IRT) using Iridium-192, Volumetric Modulated Arc Therapy (VMAT), and electron beam therapy for non-melanoma skin cancer (NMSC).

Prediction of VMAT gamma passing rates using 3D CNNs based on leaf position analysis and gradient class activation mapping for plan complexity evaluation

Medical Physics, Volume 53, Issue 5, May 2026.
Background Volumetric Modulated Arc Therapy (VMAT) is a highly conformal radiotherapy technique that enables precise tumor irradiation while sparing surrounding healthy tissue. However, the high technical demands this technique places on Linear Accelerators (LinAc) necessitate reliable quality assurance (QA) tools.

A Bayesian Causal Model for Matrix‐Valued Exposures With Applications to Radiotherapy Planning

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT In radiotherapy for cancer, organs surrounding the target tumor, known as organs‐at‐risk (OARs), should be protected from excessive radiation to avoid toxicity. Radiation exposure to multiple OARs can be summarized using matrix‐valued dose‐volume histograms (DVH), and understanding the causal relationship between DVHs and toxicity outcomes can

Metastatic malignant nerve sheath tumour in a dog

Veterinary Record Case Reports, Volume 14, Issue 2, May 2026.
Abstract A 5‐year‐old, male, English Cream Golden Retriever dog with a 3‐month history of left thoracic limb lameness was presented to the University of Georgia Veterinary Teaching Hospital. Physical examination was unremarkable. Neurological examination indicated a left peripheral C6‒T2 lesion, but further diagnostics were declined in favour of ...

A deep learning-based dose calculation method for volumetric modulated arc therapy

Radiation Oncology
Background Volumetric modulated arc therapy (VMAT) planning optimization involves iterative adjustment of numerous parameters, and hence requires repeatedly dose recalculation.
