Planning of radiotherapy capacity and productivity [PDF]

open access: yesRadiotherapy and Oncology, 2013
In the late 1990s a period of shortage of radiotherapy capacity caused long waiting times in The Netherlands. Investments in treatment vaults, equipment and training capacity were made. The developments since then are described and the actual situation is compared with the predictions throughout the years.Data are based on annual surveys on production,

Primary extranodal diffuse large B‐cell lymphoma: Molecular features, treatment, and prognosis

open access: yesAging and Cancer, Volume 3, Issue 3-4, Page 133-146, September-December 2022., 2022
One‐third of DLBCL arises from extranodal organs and is challenging to manage. Molecular features are critical to elucidate the differences in clinical features, predict the disease prognosis, and improve effective targeted therapeutic strategies. Abstract Diffuse large B‐cell lymphoma (DLBCL) is the most common subtype of non‐Hodgkin's lymphoma and ...

CT-Based Pelvic T1-Weighted MR Image Synthesis Using UNet, UNet++ and Cycle-Consistent Generative Adversarial Network (Cycle-GAN)

open access: yesFrontiers in Oncology, 2021
BackgroundComputed tomography (CT) and magnetic resonance imaging (MRI) are the mainstay imaging modalities in radiotherapy planning. In MR-Linac treatment, manual annotation of organs-at-risk (OARs) and clinical volumes requires a significant clinician ...

Feasibility of radical cardiac‐sparing, treatment planning strategies for patients with locally advanced, non‐small cell lung cancer

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose A set of treatment planning strategies were designed and retrospectively implemented for locally advanced, non‐small cell lung cancer (NSCLC) patients in order to minimize cardiac dose without compromising target coverage goals. Methods Retrospective analysis was performed for 20 NSCLC patients prescribed to 60–66 Gy that received a ...
