Lung V5 and Planning Target Volume/Lung Volume Ratio as Independent Risk Factors for ≥Grade 2 Radiation Pneumonitis after Moderately Hypofractionated Radiotherapy: A Retrospective Study

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Lung V5 and the planning target volume/lung volume ratio were identified as independent dosimetric risk factors for clinically significant radiation pneumonitis following moderately hypofractionated radiotherapy for lung cancer. Maintaining V5 < 35% may help mitigate this risk in clinical practice.

Reduced‐dose versus standard‐dose total body irradiation before allogeneic haematopoietic stem cell transplantation in adults with acute lymphoblastic leukaemia

British Journal of Haematology, EarlyView.
Summary Comparative data on reduced‐dose (8 Gy) versus standard‐dose (12 Gy) total body irradiation (TBI) before allogeneic haematopoietic stem cell transplantation (allo‐HSCT) for adults with acute lymphoblastic leukaemia (ALL) remain limited. We retrospectively analysed 101 adults undergoing first allo‐HSCT between 1999 and 2024 after 8 Gy or 12 Gy ...

OSL at elevated temperature of smart chip cards for retrospective dosimetry

Radiation Physics and Chemistry, 2023
Smart chip cards are a promising material in retrospective dosimetry due to their high collectability with low replacement cost. In this study, dose reconstruction using OSL at elevated temperatures for various chip cards was investigated. The approximate spectral emission of the chip cards was determined through a comparison of radiation-induced and ...

An institutional experience of a scripting‐driven automation of the emergent palliative radiotherapy workflow

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background Emergency palliative radiotherapy is often delivered under time‐constrained and high‐stress conditions, frequently bypassing conventional computed tomography (CT) simulation and relying on nonstandard workflows. These factors increase variability and the potential for error.
