Automatic adaptive radiotherapy triggering based on CBCT using deep learning for esophageal cancer underwent volumetric modulated arc therapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Esophageal cancer (EC) is a highly fatal malignancy for which radiotherapy plays a critical role in treatment. However, anatomical changes during radiotherapy can lead to increased doses to surrounding organs at risk (OARs). Adaptive radiotherapy (ART) is a strategy that incorporates patient‐specific anatomic changes into treatment ...

PCA‐based respiratory motion modeling for individualized PTV margin optimization in NSCLC radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Respiratory motion remains a major challenge in radiotherapy for non‐small cell lung cancer (NSCLC), often requiring a balance between target coverage and normal tissue sparing. Introduction This study aimed to develop and validate a clinically implementable, individualized PTV margin strategy by integrating principal component ...

Cross‐anatomical evaluation of a deep‐learning auto‐contouring system: qualitative, geometric, and dosimetric validation

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Accurate and consistent delineation of target and normal structures is essential for safe and effective radiotherapy. Compared with manual or atlas‐based methods, deep learning‐based auto‐contouring has demonstrated improved efficiency and reduced interobserver variability. However, its performance can vary across anatomical regions

Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging

open access: yesJournal of Medical Radiation Sciences, Volume 73, Issue 2, Page 156-163, June 2026.
This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Osteoradionecrosis After Modern Radiotherapy for Oral Cavity Cancer: Incidence and Risk Factors

open access: yesLaryngoscope Investigative Otolaryngology, Volume 11, Issue 3, June 2026.
This retrospective single‐institution review evaluated contemporary ORN rates in 172 patients with oral cavity squamous cell carcinoma treated exclusively with IMRT (2013–2022). Reported osteoradionecrosis (ORN) incidence after head and neck cancer IMRT is relatively low, however, the 3 year ORN incidence was 24% in this cohort and increased incidence ...

The Tumor Immune Microenvironment in Endometrial Cancer: Composition, Molecular Subtypes, and Therapeutic Implications

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Endometrial cancer (EC), a major gynecologic malignancy and a representative “cold tumor”, exhibits a tumor immune microenvironment (TIME) influenced by a broad range of cellular and molecular elements, immunosuppressive signals, and pathways of immune evasion.

Risk Factors and Predictive Model for Otitis Media With Effusion After Radiotherapy in Nasopharyngeal Carcinoma: A Retrospective Study

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, Volume 12, Issue 3, Page 305-315, June 2026.
ABSTRACT Objective To investigate the impact of different radiation fields on the risk of otitis media with effusion (OME) in nasopharyngeal carcinoma (NPC) patients and to develop a nomogram to identify high‐risk patients after radiotherapy. Methods Clinical data were collected from 170 NPC patients who underwent radiotherapy at Peking Union Medical ...

Bevacizumab for Radiation‐Induced (Radiculo)plexopathy

open access: yesEuropean Journal of Neurology, Volume 33, Issue 6, June 2026.
ABSTRACT Objectives Radiation‐induced (radiculo)plexopathy [RI(R)P] is a debilitating delayed neurological adverse event occurring in cancer survivors years after the irradiation of the brachial or lumbar plexuses. No effective treatments have been identified to date.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

open access: yesVeterinary and Comparative Oncology, Volume 24, Issue 2, Page 229-239, June 2026.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...
