Empty Versus Full Bladder Protocols in Radiotherapy Planning for Localised Prostate Cancer: A Dosimetric Study

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Background When planning prostate radiotherapy, full bladder preparation is widely used to displace bowel and bladder from high‐dose regions but is difficult to reproduce and can prolong workflows. Methods Twenty men with localised prostate cancer ± seminal vesicles underwent CT simulation with full and empty bladders.

Assessing dose rate distributions in VMAT plans [PDF]

Physics in Medicine and Biology, 2016
Dose rate is an essential factor in radiobiology. As modern radiotherapy delivery techniques such as volumetric modulated arc therapy (VMAT) introduce dynamic modulation of the dose rate, it is important to assess the changes in dose rate. Both the rate of monitor units per minute (MU rate) and collimation are varied over the course of a fraction ...

Sex Differences in Health‐Related Quality of Life in Patients With Head and Neck Cancer—A Prospective Study

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Objective To analyse sex differences in health‐related quality of life (HRQL) before, during and up to 3 months posttreatment of head and neck cancer, and to examine the importance of salivary secretion rate for HRQL posttreatment. Methods Patients were recruited before starting curative oncologic treatment.

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

Veterinary and Comparative Oncology, EarlyView.
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, EarlyView.
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 ...

Association of recurrence patterns and outcome with HR and HER2 status in patients with resected brain metastases from breast cancer

International Journal of Cancer, Volume 159, Issue 2, Page 440-449, 15 July 2026.
What's new? While treatment strategies for solid brain metastases have been relatively uniform across cancer subtypes, tailored approaches are warranted. In this observational study, intracranial recurrences after microsurgical resection occurred significantly earlier and more frequently at distant sites in patients with triple‐negative breast cancer ...

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.

Explainable machine learning for patient‐specific quality assurance in intensity‐modulated radiotherapy based on anatomical structures

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Patient‐specific quality assurance (PSQA) plays a pivotal role in intensity‐modulated radiotherapy (IMRT) to ensure accurate dose delivery. However, conventional measurement‐based PSQA approaches are labor‐intensive and provide limited insight into the underlying factors contributing to variations in gamma passing rates (GPRs ...
