Cardiac mortality and morbidity during breast cancer treatment can be caused by both radiotherapy and chemotherapy. As chemotherapy cannot be omitted due its proven overall survival benefit, newer radiotherapy techniques like DIBH with Real-time Position Monitoring (RPM), have been devised to minimise dose to the heart without compromising target coverage. Very sparse prospective data look into the benefit of DIBH in chest wall radiotherapy. Aim: To determine dosimetrically whether DIBH reduces the cardiac (heart and left anterior descending [LAD] artery) and ipsilateral lung doses compared to FB, in patients receiving radiotherapy to left side chestwall with 3D-CRT technique and to quantify it. Material and methods: 25 consecutive left sided postmastectomy breast cancer patients with minimum breath hold duration more than 15 seconds were selected. 2 plans were made for each patient u..
