Outcomes and toxicities of definitive radiotherapy and reirradiation using 3‐dimensional conformal or intensity‐modulated (pencil beam) proton therapy for patients with nasal cavity and paranasal sinus malignancies

open access: yesCancer, 2020
Proton therapy (PT) improves outcomes in patients with nasal cavity (NC) and paranasal sinus (PNS) cancers. Herein, the authors have reported to their knowledge the largest series to date using intensity‐modulated proton therapy (IMPT) in the treatment ...

Feasibility Study of Robust Optimization to Reduce Dose Delivery Uncertainty by Potential Applicator Displacements for a Cervix Brachytherapy

open access: yesApplied Sciences, 2021
Brachytherapy is an important technique to increase the overall survival of cervical cancer patients. However, a possible shift of the applicators in relation to the target and organs at risk may occur between imaging and treatment.

Proton versus photon radiation therapy: A clinical review

open access: yesFrontiers in Oncology, 2023
While proton radiation therapy offers substantially better dose distribution characteristics than photon radiation therapy in certain clinical applications, data demonstrating a quantifiable clinical advantage is still needed for many treatment sites ...

Online daily adaptive proton therapy.

open access: yesBritish Journal of Radiology, 2020
It is recognised that the use of a single plan calculated on an image acquired some time before the treatment is generally insufficient to accurately represent the daily dose to the target and to the organs at risk. This is particularly true for protons,

Clinical commissioning of intensity modulated proton therapy systems: Report of AAPM Task Group 185.

open access: yesMedical Physics (Lancaster), 2020
Proton therapy is an expanding radiotherapy modality in the United States and worldwide. With the number of proton therapy centers treating patients increasing, so does the need for consistent, high-quality clinical commissioning practices.

Proton therapy delivery: What is needed in the next ten years?

open access: yesBritish Journal of Radiology, 2020
Proton radiation therapy has been used clinically since 1952, and major advancements in the last 10 years have helped establish protons as a major clinical modality in the cancer-fighting arsenal.

Comparison of pencil beam and Monte Carlo calculations with ion chamber array measurements for patient-specific quality assurance

open access: yesRadiation Medicine and Protection, 2022
Objective: To determine under what conditions and criteria comparisons between calculations made with the current clinical treatment planning system (Syngo) and an in-house built TPS (TIMPS) would allow skipping of in-beam portal-specific measurements ...

Development of a Comprehensive, Contour-Based, Peer Review Workflow at a Community Proton Center [PDF]

open access: yesInternational Journal of Particle Therapy, 2020
Purpose: Quality assurance and continuing quality improvement are integral parts of any radiation oncology practice. With increasingly conformal radiation treatments, it has become critical to focus on every slice of the target contour to ensure adequate
