Clinical implementation and feasibility of long-course fractionated MR-guided chemoradiotherapy for patients with esophageal cancer: An R-IDEAL stage 1b/2a evaluation of technical innovation.

Purpose: This R-Ideal stage 1b/2a study describes the workflow and feasibility of long-course fractionated online adaptive MR-guided chemoradiotherapy with reduced CTV-to-PTV margins on the 1.5T MR-Linac for patients with esophageal cancer.

Methods: Patients with esophageal cancer scheduled to undergo chemoradiation were treated on a 1.

Prone vs. supine accelerated partial breast irradiation on an MR-Linac: A planning study.

Background And Purpose: Accelerated partial breast irradiation (APBI) may benefit from the MR-Linac for target definition, patient setup, and motion monitoring. In this planning study, we investigated whether prone or supine position is dosimetrically beneficial for APBI on an MR-Linac and we evaluated patient comfort.

Materials And Methods: Twenty-patients (9 postoperative, 11 preoperative) with a DCIS or breast tumor <3 cm underwent 1.

On the Development of a Light Dosimetry Planning Tool for Photodynamic Therapy in Arbitrary Shaped Cavities: Initial Results.

Previous dosimetric studies during photodynamic therapy (PDT) of superficial lesions within a cavity such as the nasopharynx, demonstrated significant intra- and interpatient variations in fluence rate build-up as a result of tissue surface re-emitted and reflected photons, which depends on the optical properties. This scattering effect affects the response to PDT. Recently, a meta-tetra(hydroxyphenyl)chlorin-mediated PDT study of malignancies in the paranasal sinuses after salvage surgery was initiated.

[Supervising quality of care through the patients' eyes; a different approach to inspection is required].

The Netherlands Health and Youth Care Inspectorate (IGJ) wants to take the patient's perspective into account more often in its supervision of quality of care. The inspectorate already has some insight into this perspective via patients' reports; patients report complaints with the aim of preventing recurrence of the problem. However, the inspectorate does not further investigate the vast majority of these complaints and, furthermore, complaints with a clinical aspect are investigated far more often than organisational or communicational problems.
