Reirradiation: Standards, challenges, and patient‐focused strategies across tumor types

open access: yesCA: A Cancer Journal for Clinicians, EarlyView.
Abstract Reirradiation (reRT), defined as administering a course of radiation therapy to a specific area previously irradiated, is an evolving treatment strategy for locoregionally recurrent cancer that offers significant potential and poses inherent challenges.

Consolidation, Systematic Appraisal and Comparison of Guideline Recommendations Regarding Management of Chronic Pain: Protocol for a Digital Chronic Pain Recommendation Map

open access: yesClinical and Public Health Guidelines, Volume 2, Issue 4, October 2025.
ABSTRACT Introduction Chronic pain affects 1 in 5 adults and children globally; however, management remains highly variable and low value care is common. Inconsistent recommendations among clinical practice guidelines for management of chronic pain contribute to suboptimal patient management.

Characterization of a 0.5 × 0.5 mm plastic scintillating detector for small field dosimetry: Its performance and comparison with other commercially available plastic scintillating detectors

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Background Lack of an ideal detector for small field dosimetry has led to the development of many new types of detectors. Recent studies have shown that plastic scintillation detectors (PSDs) provide favorable dosimetric characteristics, such as minimal volume averaging and fluence perturbation effects, real time response rates, high signal to

Optimizing lung SBRT delivery: A hybrid approach combining dynamic conformal arc (DCA) and volumetric modulated arc therapy (VMAT) techniques

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Purpose This study introduces and evaluates a hybrid dynamic conformal arc‐volumetric modulated arc therapy (hDCA‐VMAT) technique for lung stereotactic body radiotherapy (SBRT). The goal is to combine the planning efficiency of VMAT with the delivery robustness of dynamic conformal arc (DCA) techniques, particularly for low‐density lung ...

Evaluation of intra‐fractional target displacement by patient motion during a single‐isocenter multi‐target stereotactic radiation therapy for brain metastases

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Background Single‐isocenter multi‐target volumetric modulated arc therapy (SIMT‐VMAT) has been implemented widely in fractionated stereotactic radiosurgery (fSRS) to treat brain metastases. The impact of rotational intra‐fractional patient motion (IFPM) is influenced by the distance between the geometric target's center and the isocenter (DTI).

Machine learning and lean six sigma for targeted patient-specific quality assurance of volumetric modulated arc therapy plans

open access: yesPhysics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy plans with excessive complexity exhibit higher uncertainties and worse patient-specific quality assurance (PSQA) results, while the workload of measurement-based PSQA can impact the efficiency of the radiotherapy ...

A predictive quality assurance model for patient‐specific gamma passing rate of hyperarc‐based stereotactic radiotherapy and radiosurgery of brain metastases

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 9, September 2025.
Abstract Objective Measurement‐based patient specific quality assurance (PSQA) is an increasingly debated topic among medical physicists. Developments like online adaptive radiotherapy and same‐day stereotactic treatments limit the time to do measurement‐based PSQA. Herein, we develop a predictive machine learning model to supplement PSQA by predicting
