Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
After completing the standard of care planning MRI scans, participants will be asked to complete a short (10-15 mins) anonymous survey on an electronic platform to ask about their experience of the MRI scan and whether they have a preference for the supine or prone position. Participants will be asked to indicate their agreement with a statement on a Likert scale, and have the opportunity to provide answers to open- ended questions, There are no changes to standard treatments for participants.

Outcomes
Primary outcome [1] 336731 0
Quantification of image distortion in both the supine and prone positions to allow comparison and determine whether there is a patient or position specific difference.
Timepoint [1] 336731 0
Single timepoint post data collection from MRI simulation session.
Primary outcome [2] 337863 0
Measurement of relative distance from the Planning Target Volume (PTV) to the Organs At Risk (OAR) in the supine and prone positions.
Timepoint [2] 337863 0
Single timepoint post data collection on the same dataset from the MRI simulation session.
Primary outcome [3] 337864 0
Assessment of breathing motion for each patient in each position to determine whether this effect is more prominent in either position.
Timepoint [3] 337864 0
Single timepoint post data collection on the data from the MRI simulation session.
Secondary outcome [1] 433501 0
Assessment of dose differences (dose in Gray) to the target, organs at risk and normal tissue for each patient plan between the supine and prone positions on synthetic CTs generated from the MRI scans. This will be assessed as a composite secondary outcome.
Timepoint [1] 433501 0
Single timepoint post data collection on the data from the MRI simulation session.
Secondary outcome [2] 433502 0
Analyse survey responses (content analysis) to assess whether there is a patient preference for the supine or prone position.
Timepoint [2] 433502 0
Single timepoint, one survey will be completed directly after the MRI simulation appointment.

Summary
Brief summary
The aim of this study is to compare the benefits and limitations of different positioning options for early breast cancer patients who are suitable for partial breast treatment on the Magnetic Resonance integrated Linac.

Who is it for?
You may be eligible for this study if you are a female age 40 or older, with early stage breast cancer and suitable for accelerated partial breast radiotherapy.

Study details
Participants will receive both a supine (on your back) and prone (on your tummy) scan in the MRI and a CT scan in the ideal treatment position (supine OR prone) as per our usual standard of care. Participants will then be asked to complete a short (10-15 mins) anonymous survey on an electronic platform to ask about their experience of the MRI scan and whether they have a preference for the supine or prone position. There are no changes to standard treatments for participants.

It is hoped that the findings from this study will streamline the simulation process for APBI patients and help us to determine who would benefit from which position without needing to complete both scans. It is also hoped that this information can be used across our other treatment machines to benefit patients who may not be able to have an MRI scan to work out the best position for them.
