Use of Moderate Deep Inspiration Breath Hold for Loco-Regional Radiotherapy of Right Breast Cancer including Internal Mammary Lymph Nodes

Loco-regional radiotherapy (RT) of the breast or chestwall may include the internal mammary lymph nodes (IMN). Inclusion of these lymph nodes with a conventional four field technique may give rise to an increased volume of lung in the treated volume. At our centre patients receiving RT to the left breast are usually simulated and treated using a moderate Deep Inspiration Breath Hold (mDIBH) technique in an attempt to reduce dose to the heart. Patients receiving RT to the right breast or chestwall including the IMN may benefit from treatment with the mDIBH technique by reducing doses to organs at risk (OAR).
