Acute toxicity and quality of life after margin reduction using a sub-fractionation workflow for stereotactic radiotherapy of localized prostate cancer on a 1.5 Tesla MR-linac

Tariq A. Lalmahomed, T. Willigenburg, Sandrine M.G. van de Pol, Eline N. de Groot-van Breugel et autres

BACKGROUND AND PURPOSE: A sub-fractionation workflow to correct for intrafraction motion in localized prostate cancer radiotherapy was implemented at our center, allowing for PTV margin reduction from isotropic 5 mm to 2 mm in cranio-caudal and left-right directions and 3 mm in …

Treatment planning for MR-guided SBRT of pancreatic tumors on a 1.5 T MR-Linac: A global consensus protocol

Guus Grimbergen, Hidde Eijkelenkamp, Louk M.W. Snoeren, Rana Bahij et autres

Background and purpose Treatment planning for MR-guided stereotactic body radiotherapy (SBRT) for pancreatic tumors can be challenging, leading to a wide variation of protocols and practices. This study aimed to harmonize treatment planning by developing a consensus planning protocol for MR-guided pancreas …

Stereotactic body radiotherapy of central lung tumours using a 1.5 T MR-linac: First clinical experiences

Laura G. Merckel, Jacquelien Pomp, Sara Lyons Hackett, Astrid L.H.M.W. van Lier et autres

Background: MRI-guidance may aid better discrimination between Organs at Risk (OARs) and target volumes in proximity of the mediastinum. We report the first clinical experiences with Stereotactic Body Radiotherapy (SBRT) of (ultra)central lung tumours on a 1.5 T MR-linac. Materials and Methods: …

On the feasibility of cardiac substructure sparing in magnetic resonance imaging guided stereotactic lung radiotherapy

Luuk H.G. van der Pol, Sara Lyons Hackett, Firdaus A. A. Mohamed Hoesein, Louk M.W. Snoeren et autres

Abstract Background Lung stereotactic body radiotherapy (SBRT) has proven an effective treatment for medically inoperable lung tumors, even for (ultra‐)central tumors. Recently, there has been growing interest in radiation‐induced cardiac toxicity in lung radiotherapy. More specifically, dose to cardiac (sub‐)structures (CS) was …

Online adaptive MR-guided radiotherapy: Conformity of contour adaptation for prostate cancer, rectal cancer and lymph node oligometastases among radiation therapists and radiation oncologists

Marnix J. A. Rasing, G.G. Sikkes, Nicole G.P.M. Vissers, A.N.T.J. Kotte et autres

Background and purpose: Online adaptive MR-guided treatment planning workflows facilitate daily contour adaptation to the actual anatomy. Allocating contour adaptation to radiation therapists (RTTs) instead of radiation oncologists (ROs) might allow for increasing workflow efficiency. This study investigates conformity of adapted target …

Impact of magnetic resonance-guided versus conventional radiotherapy workflows on organ at risk doses in stereotactic body radiotherapy for lymph node oligometastases

Anita M. Werensteijn-Honingh, P.S. Kroon, Dennis Winkel, J Gaál et autres

Background and purpose Magnetic resonance (MR)-linac delivery is expected to improve organ at risk (OAR) sparing. In this study, OAR doses were compared for online adaptive MR-linac treatments and conventional cone beam computed tomography (CBCT)-linac radiotherapy, taking into account differences in clinical …
