Dosimetric Comparison Using an Intraoral Stent during Volumetric-modulated Arc Therapy in a Patient with Carcinoma of the Tongue

Journal of Radiation and Cancer Research
A 47-year-old man diagnosed with carcinoma of the tongue and postsurgery was planned for adjuvant radiotherapy. He was simulated for radiotherapy with or without an acrylic intraoral stent (IOS). Two different radiotherapy treatment plans with volumetric-

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Develop a novel non‐coplanar trajectory optimization algorithm for an efficient 4pi spot‐scanning proton Arc (SPArc‐4pi) treatment delivery

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background The degree of freedom has been recognized as a key factor in particle beam therapy, such as improving the dose conformity and linear energy transfer distributions. Therefore, proton arc therapy has drawn significant interest in the Society of Radiation Oncology as a potentially efficient and optimal treatment option for cancer ...

Retrospective Analysis of Survival and Adverse Effects Associated With Stereotactic Body Radiation Therapy in 12 Dogs With Hepatocellular Carcinoma

Veterinary and Comparative Oncology, Volume 24, Issue 3, Page 485-498, September 2026.
ABSTRACT This retrospective analysis evaluated 12 dogs with hepatocellular carcinoma (HCC) who received stereotactic body radiation therapy (SBRT). Dogs received between 6 and 25 Grey (Gy) per fraction for 1–5 fractions for a total dose of 13–30 Gy. Eleven patients (92%) experienced acute adverse effects (AE), with the majority being VRTOG grade 2–3 ...

The Definitive‐Intent 10‐Fraction Radiotherapy Protocol (‘The Zurich Protocol’) Yields Lasting Tumour Control and Survival in Dogs With Intracranial Meningiomas

Veterinary and Comparative Oncology, Volume 24, Issue 3, Page 601-610, September 2026.
ABSTRACT Moderately hypofractionated definitive‐intent radiotherapy protocols can be used for canine intracranial meningiomas to shorten overall treatment time while maintaining tumour control and limiting normal tissue toxicity. This retrospective study evaluated oncologic outcomes, toxicity, and radiation dose‐volume‐related prognostic factors in ...

End‐to‐end deep learning pipeline for automated IMRT planning in lymphoma: Feasibility and limitations

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Intensity‐modulated radiation therapy (IMRT) is widely used for lymphoma because a multileaf collimator (MLC) can sculpt dose around irregular targets. Planning, however, is time‐consuming and difficult to standardize. Fluence map prediction (FMP) using deep learning (DL) could potentially be used to automate planning, but it has ...
