Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Description of intervention: Magnetic resonance image guided single fraction (21Gy) neo-adjuvant breast radiotherapy administered over a period of 5-10 minutes approximately 6 weeks prior to surgery. Fraction will be delivered to a single lesion by a multidiciplinary team including Radiation Oncologist, radiation therapist, medical physicist and MR radiographers. The fraction delivered will be recorded in the patients medical record and will be reviewed by the clinical team prior to surgery.

Outcomes
Primary outcome [1] 325815 0
To determine the feasibility of MRI guided single fraction neo-adjuvant breast radiotherapy. Feasibility will be defined as the ability to plan and deliver a pre-operative single fraction of SABR within 48 hours. This will be collected from data linkage with hospital electronic medical records.
Timepoint [1] 325815 0
Monitored from trial entry to delivery of intervention
Secondary outcome [1] 389228 0
Pathological response in resected tumour tissue following the delivery of intervention and in 12 months follow up as assessed by PET/MRI imaging.
Timepoint [1] 389228 0
At time of surgery and time of disease progression or 12 months post treatment, which ever occurs first.
Secondary outcome [2] 391023 0
Quantitative comparison between planning volumes and dosimetry for planning-MR image guidance vs. CT for planning-CBCT image guidance.
Timepoint [2] 391023 0
Enrollment on study until delivery of intervention
Secondary outcome [3] 396264 0
Quantification of dosimetric differences comparing CT and Cone Beam CT.
Timepoint [3] 396264 0
Radiation therapy planning period which occurs pre-dose administration.
Secondary outcome [4] 396285 0
To evaluate the impact of MRI guided single fraction neo-adjuvant breast radiotherapy on quality of life as measured by EORTC QLQ-C30 and QLQ-BR23.
Timepoint [4] 396285 0
Report measurements will occur at study enrolment, on day of radiotherapy treatment after treatment, two weeks post-surgery and at 12 month follow up.
Secondary outcome [5] 396286 0
Exploratory outcome measure: quantification of changes in blood biomarkers before and after intervention.
Timepoint [5] 396286 0
Study enrolment, on day of radiotherapy treatment after treatment, two weeks post-surgery and at 12 months follow up.

Efficacy
Statistical methods / analysis
Descriptive summary statistics will be prepared to report the proportion of patients who can be feasibly treated with the MRI guided single fraction techniques using adapt to position and shape.
Secondary measures that will be collected as categorical values (i.e. Clavien grade) will be presented as counts and percentage frequency, while continuous variables (i.e. Quality of Life or Patient Reported Outcome Measures) will be presented as mean ± standard deviation if normally distributed or median (Inter-quartile range) if skewed. Appropriate parametric or non-parametric tests will be applied if comparisons between groups are possible. Rate of recurrence will be considered via time to event analysis using the Kaplan-Meier method and cox regression analysis if the sample size allows.
Statistical analysis will be conducted using Stata v15.1 (StataCorp, College Station, Texas, USA) with a p-value of less than 0.05 considered to indicate statistical significance.

Summary
Brief summary
This trial is investigating the feasibility of pre-operative high-dose radiation in early breast cancer patients.

Who is it for?
You may be eligible for this trial if you are a female aged 60 or over, with unifocal breast cancer graded <3 on core biopsies. You must also be oestrogen and progesterone receptor positive, and clinically node negative.

Study details
Parents recruited to this study will be offered a high radiation dose delivered in a single treatment using an MRI-guided linear accelerator, 6 weeks prior to surgery. They will be followed up for disease response and progression.

It is hoped that this study will help investigators examine the feasibility of pre-operative single dose radiotherapy, which may reduce patient inconvenience as well as potentially decreasing side effects of extended radiation treatment.
