Boost Approaches in Patients Undergoing Postoperative Radiotherapy

open access: yesJournal of Surgical Oncology, Volume 133, Issue 6, Page 773-784, May 2026.
ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Clinical validation of a high‐definition mid‐position magnetic resonance imaging approach for lung radiotherapy planning

open access: yesMedical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Respiratory‐correlated four‐dimensional (4D) magnetic resonance imaging (4D‐MRI) is useful to estimate breathing induced motion for MRI‐guided radiotherapy. Based on 4D‐MR image sets, a three‐dimensional mid‐position (MidP) MRI can be generated using deformable image registration (DIR) for radiotherapy planning. However, the desired

Prediction of VMAT gamma passing rates using 3D CNNs based on leaf position analysis and gradient class activation mapping for plan complexity evaluation

open access: yesMedical Physics, Volume 53, Issue 5, May 2026.
Background Volumetric Modulated Arc Therapy (VMAT) is a highly conformal radiotherapy technique that enables precise tumor irradiation while sparing surrounding healthy tissue. However, the high technical demands this technique places on Linear Accelerators (LinAc) necessitate reliable quality assurance (QA) tools.

Deep Learning‐Based Particle Tracking Velocimetry (PTV) for Spherical and Non‐Spherical Particles: Application to Sediment Transport

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Particle‐resolved measurements in physical experiments are crucial to the study of sediment transport. Conventional particle tracking velocimetry (PTV) relies on template matching of simple shapes via intensity thresholding and nearest‐neighbor linking.

At the Right Time: Temporal Precision in Personalised Medicine

open access: yesSociology of Health &Illness, Volume 48, Issue 4, May 2026.
ABSTRACT Personalised medicine was initially heralded as delivering ‘the right drug to the right patient at the right time’. Although molecular precision has dominated recent developments, the temporal dimension has remained underexplored. This paper examines how temporal precision is emerging as a defining feature of next‐generation precision medicine,

Programmed Death‐Ligand 1 Expression Predicts Poor Prognosis in Patients With Early‐Stage Non‐Small‐Cell Lung Cancer Undergoing Stereotactic Body Radiotherapy

open access: yesThoracic Cancer, Volume 17, Issue 9, May 2026.
PD‐L1 expression is independently associated with inferior survival outcomes and increased regional recurrence in early‐stage NSCLC treated with SBRT. These findings suggest that PD‐L1 status serves as a prognostic biomarker for identifying high‐risk patients who may benefit from intensified systemic strategies, such as combining SBRT with ...

Stage III Lymph Node–Positive Non‐Small‐Cell Lung Cancer Patients With or Without Lymph Node Irradiation by Stereotactic Body Radiation Therapy: Propensity Score–Matched Analysis

open access: yesThe Clinical Respiratory Journal, Volume 20, Issue 5, May 2026.
ABSTRACT Purpose This study compared the local control (LC) and survival of patients with stage III lymph node–positive non‐small‐cell lung cancer (NSCLC) who received lymph node irradiation (LNs R+) and those who did not (LNs R−). Methods We retrospectively reviewed patients with stage III LN–positive NSCLC who underwent stereotactic body radiotherapy
