Abstract


Due to the overall improvements in breast cancer treatment, long-term cause specific survival has improved significantly over the past few decades. Radiotherapy is an essential component of multimodal breast cancer treatment. However, with the increasing use of radiotherapy and the larger number of women surviving for many years after treatment, more patients are at risk of developing chronic toxicities associated with their care. In particular, toxicities to the heart carry the potential for reduced survival. In conventional breast radiotherapy the patient is breathing freely, however, several techniques have recently been used to reduce the volume of cardiac tissue in the radiation field. Amongst them is Voluntary Inspiration Breath Hold (VIBH), where the patient holds a quantified inspiration for the duration of treatment delivery. By holding inspiration during beam on, the distance between the chest wall and cardiac structures is increased (Fig 1). This increased distance can be exploited in order to reduce the radiation dose received by the heart. VIBH is an evidence based, simple, inexpensive, and equipment free breath holding technique, with proven inter and intrafraction reproducibility. Breath hold consistency is monitored prior to and during radiotherapy delivery by means of in room treatment lasers and imaging. Dosimetric studies demonstrate a reduction in dose to cardiac tissue when VIBH is applied without compromise of target volume coverage. This presentation presents background analysis of the need for cardiac sparing techniques in left sided breast radiotherapy along with practical insights with respect to its real time clinical application of the VIBH technique.
