Accuracy and workflow efficiency of surface-guided open-face vs. closed-face masks in SRT/SRS for brain metastases
Background: Open-face masks (OFMs) provide comparable immobilization or superior accuracy with greater patient comfort than closed-face masks (CFMs), but their impact on workflow efficiency in stereotactic radiotherapy (SRT) and radiosurgery (SRS) for brain metastases remains unclear. This study…

Decreased overall survival in patients with brain metastases from non-small cell lung cancer with radiotherapy dose on the neurogenic niches
Background: Non-small cell lung cancer (NSCLC), the most common type of lung cancer frequently leads to brain metastases (BMs), which are associated with a poor prognosis. Radiotherapy is the main treatment for BMs, but irradiates healthy tissue, including neural stem cells (NSCs). NSCs reside in…

Time toxicity in CBCT-guided radiation therapy: A retrospective analysis of unplanned imaging burden across disease sites
Purpose: Adaptive radiotherapy (ART) enhances treatment precision by adjusting for anatomical changes identified during a course of treatment. While ART is resource-intensive, non-adaptive workflows may also incur significant time and resource burden due to reactive interventions. This study aims…

Feasibility of transitioning to marker-less immobilisation using optical surface guidance in head and neck cancer treatment: a study at territory state cancer centre in a developing country
Purpose/Objective(s): In countries such as India, where a large share of cancer patients undergoes head and neck radiotherapy, setups still rely primarily on laser alignment with surface markers on the mask. This study explores transitioning from conventional marker-based setup to markerless setups…

Radiation therapist led treatment of lung stereotactic ablative body radiation therapy patients in the absence of the radiation oncologist – An image matching consistency comparison study
Introduction: The aim of this study was to evaluate the consistency of day 1 cone-beam computed tomography (CBCT) image registration in lung stereotactic ablative body radiation therapy (SABR) among radiation oncologists (RO), radiation therapists (RTT) and paired RTTs, negating the need for RO to…

A reirradiation workflow for managing patients with treatments planned in a multi-TPS environment
Reirradiation is becoming more common. Safe and effective implementation relies on accurate dose accumulation methodology, complex treatment planning, and multidisciplinary communication. Clinical workflow guidance to address these challenges is needed. Herein we report a TPS-agnostic reirradiation…

Comparative dosimetric analysis of deep inspiration breath-hold versus free breathing radiotherapy in lung cancer: special emphasis on cardiac and subcardiac structure protection
Background: Radiation therapy (RT) plays a central role in the treatment of lung cancer. However, cardiac and pulmonary toxicities remain major concerns. Deep inspiration breath-hold (DIBH) has been shown to improve target stability and reduce organ-at-risk (OAR) exposure, but data in lung cancer…
