The primary purpose of this trial is to evaluate whether deep inhalation breath hold (DIBH) is feasible and effective for reducing the radiation dose to the heart during radiotherapy for cancer of the left breast. Who is it for? You may be eligible to enroll in this trial if you are aged 18 or over and have been diagnosed with breast cancer (left or right breast) for which radiotherapy treatment is planned following breast conserving surgery or mastectomy. Study details There will be two groups .... Read more

The purpose of the trial is to demonstrate the feasibility to evaluate Deep Inhalation Breath Hold (DIBH) countrywide as demonstrated in patient compliance and reproducibility of set-up. The trial is a two-arm study assessing the feasibility of DIBH during Radiotherapy treatment: the intervention group corresponds to left-sided breast cancer patients whereas the control group corresponds to right sided breast cancer patients. Left sided breast cancer patients who do not proceed to treatment with .... Read more
Control group Active
Right sided breast cancer participants and Left sided breast cancer participants who fail DIBH to receive standard of care radiotherapy only
Outcome: Primary Outcome - Feasibility of DIBH Feasibility will be determined by three factors: 1. Favourable DIBH plan: The difference in the geometric relation between heart and target volume in free breathing and DIBH which will be assessed in the direct comparison of treatment plans developed for the two CT scans acquired for the trial. DIBH plan will be considered favourable if the target volume DVH parameters can be assumed to be clinically non-inferior, the lung DVH is b .... Read more
Outcome: Magnitude of the potential impact of DIBH on cardiac dose in patients undergoing radiotherapy for left-sided breast cancer Magnitude of the potential impact of DIBH will be assessed by looking at the mean dose to the heart using DIBH RT plan and the dose to the heart using free breathing plan. The software used to develop the RT plans will measure/capture the mean dose to the heart. Timepoint: When left-sided breast cancer participants have completed RT planning f .... Read more
