Dosimetric comparison of TG‐43 formalism and HU‐based AcurosBV algorithms in HDR brachytherapy for head‐and‐neck superficial lesions with H.A.M. applicators

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background TG‐43 formalism assumes homogeneous water media, potentially overlooking anatomical heterogeneities that affect dose accuracy. AcurosBV, a model‐based dose calculation algorithm, accounts for tissue and material heterogeneities. This study evaluates their dosimetric differences in high‐dose‐rate (HDR) brachytherapy using Harrison ...

COVID-19 and influenza vaccination among adults stably engaged in HIV care

Vaccine: X
Introduction: Vaccination against COVID-19 and influenza is recommended for people living with HIV, but real-world uptake data remain incomplete, especially in populations facing socioeconomic barriers. We assessed uptake and associated factors at an HIV

Experimental evaluation of an intraoperative‐imaging based workflow for electron beam radiotherapy of pancreatic cancer using in situ dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Purpose The aim of this study is to perform an experimental evaluation of an imaging‐based intraoperative electron beam radiotherapy (IOERT) and in vivo dose verification workflow for pancreatic cancer on a porcine cadaver. Materials and methods The Imaging Ring m (ImR) mobile cone‐beam computed tomography (CBCT) scanner (medPhoton GmbH ...

Effect of First‐Line Chemotherapy Alone Versus First‐Line Chemotherapy Plus Radiotherapy on Survival in Patients With Locally Advanced Pancreatic Cancer in the IMRT Era: A Retrospective Cohort Study

Cancer Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background The role of intensity‐modulated radiotherapy (IMRT) and novel combination chemotherapy regimens in locally advanced pancreatic cancer (LAPC) remains unclear. In this study, we focused on comparing survival between first‐line chemotherapy alone and first‐line chemotherapy plus IMRT in patients with LAPC.

Direct optimization of the probability of lesion origin in proton treatment planning for low‐grade glioma patients

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background In proton therapy of low‐grade glioma (LGG) patients, contrast‐enhancing brain lesions (CEBLs) on magnetic resonance imaging are considered predictive of late radiation‐induced lesions. From the observation that CEBLs tend to concentrate in regions of increased dose‐averaged linear energy transfer (LETd) and proximal to the ...

A simulation study of a novel spiral volumetric modulated arc therapy for enhanced dose delivery efficiency and quality in radiotherapy

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Conventional volumetric modulated arc therapy (VMAT) is limited by its longitudinal field size for large targets, often requiring multiple isocenters, while Helical Tomotherapy (HT) offers superior longitudinal conformity but suffers from prolonged treatment times due to its narrow fan beam.
