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 ...

Volumetric-modulated arc therapy (VMAT) versus 3D-conformal radiation therapy in supra-diaphragmatic Hodgkin’s Lymphoma with mediastinal involvement: A dosimetric comparison

Journal of the Egyptian National Cancer Institute, 2016
Purpose: To compare volumetric-modulated arc therapy (VMAT) with 3D-conformal radiation therapy (3D-CRT) mediastinal irradiation for stage I–II supra-diaphragmatic Hodgkin’s Lymphoma (HL). Patients and methods: Eleven patients were planned for RT after 4–

Application of an updated severity‐based FMEA approach to Radiation Therapy QA: A multi‐institutional exercise

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background External beam radiation therapy (RT) involves many complex steps to safely and reliably treat patients. The radiation oncology community has adopted process maps and failure modes and effects analysis (FMEA) to analyze risk using the TG‑100 methodology, but the traditional TG‑100–endorsed risk priority number (RPN) has recognized ...

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.

Spine SBRT using VMAT

Journal of Physics: Conference Series, 2017
Metastases of the spinal column are common amongst cancer patients with approximately 18,000 new cases in North America each year that require urgent treatment. Historically radiation therapy doses have been limited due to the proximity of the spinal cord.

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 ...
