Online MR guided dose escalated radiotherapy for organ preservation in distal rectal cancer

Clinical and Translational Radiation Oncology, 2022
Introduction: Non-surgical management of rectal cancer aiming for organ-preservation is an important development to improve rectal cancer treatment. Dose escalated radiotherapy represents one approach to increase clinical complete response (cCR) rates ...

Use of radiobiological modeling in treatment plan evaluation and optimization of prostate cancer radiotherapy [PDF]

, 2011
There are many tools available that are used to evaluate a radiotherapy treatment plan, such as isodose distribution charts, dose volume histograms (DVH), maximum, minimum and mean doses of the dose distributions as well as DVH point dose constraints ...

Experimental validation of multi-fraction online adaptations in magnetic resonance guided radiotherapy

Physics and Imaging in Radiation Oncology, 2023
Background and purpose: Radiotherapy plan verification is generally performed on the reference plan based on the pre-treatment anatomy. However, the introduction of online adaptive treatments demands a new approach, as plans are created daily on ...

PD-L1 blockade enhances response of pancreatic ductal adenocarcinoma to radiotherapy [PDF]

, 2017
Pancreatic ductal adenocarcinoma (PDAC) is considered a non‐immunogenic tumor, and immune checkpoint inhibitor monotherapy lacks efficacy in this disease. Radiotherapy (RT) can stimulate the immune system.

Feasibility of tumour-focused adaptive radiotherapy for bladder cancer on the MR-linac

Clinical and Translational Radiation Oncology, 2022
Bladder tumour-focused magnetic resonance image-guided adaptive radiotherapy using a 1.5 Tesla MR-linac is feasible. A full online workflow adapting to anatomy at each fraction is achievable in approximately 30 min. Intra-fraction bladder filling did not
