Conclusion:

The use of a second coaching session seems to reduce fraction treatment times as a result of a better EBH stability.

This is a preliminary study that has to be extended to more patients in order to obtain statistically significant results.

Purpose/Objective:

In radiotherapy (RT), respiratory motion management (RMM) using a breath-hold (BH) technique can be utilised to suppress tumour motion and hence reduce the dose to organs-at-risk (OARs). Deep Inspiration Breath-Hold (DIBH) is a common technique that has proven to be highly effective at reducing the cardiac dose for patients undergoing radiotherapy for left breast cancer. There exists a gap in the guidelines for the technologies and practices followed when using DIBH to treat left-sided breast cancer patients. This study aims to explore the use of breath hold practices across Ireland.
