Radiotherapy Delivery in Deep Inspiration for Pediatric Patients—Final Results of the Phase II Feasibility Study TEDDI

Pediatric Blood &Cancer, Volume 73, Issue 4, April 2026.
Abstract Introduction The TEDDI trial tested the feasibility and reproducibility of deep‐inspiration breath‐hold (DIBH) in pediatric patients referred for radiotherapy. This report presents final results, including patient‐reported outcomes (PRO) and dosimetric comparison of DIBH and free‐breathing (FB).

Influence of Normal Tissue Objective Tools on Treatment Planning System in Nasopharyngeal Carcinoma (NPC): A 3D Printed Anthropomorphic Phantom Study [PDF]

Iranian Journal of Medical Physics
Introduction: The normal tissue objective (NTO), one of the new aspects in the radiation treatment planning system (TPS), aims to lower the absorbed dose received by organs at risk (OARs) close to the target volume or Planning Target Volume (PTV).

Quantitative evaluation of the effect of anatomical changes on the results of in vivo dosimetry during radiation therapy in the thoracic region

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Anatomical changes during thoracic radiation therapy can alter dose delivery and compromise accuracy. Electronic portal imaging device (EPID)‐based in vivo dosimetry (IVD) enables noninvasive monitoring of these changes during treatment. Purpose This study quantitatively evaluated the impact of EPID‐based IVD in volumetric modulated

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.
