Study ID: NCT02497664

Study Description

Brief Summary: Neo-adjuvant chemoradiotherapy (neo-CRT) is increasingly applied in the curative treatment of esophageal cancer, with the aim to downstage the tumor, to increase the rate of radical resections, and consequently to improve the survival rates. Due to improved survival, it will become increasingly important to minimize the radiation-induced toxicity among long-term survivors. In the management of locally advanced non small cell lung cancer (NSCLC), radiotherapy is the standard treatment modality. However, the dose that can be safely applied to the tumour is limited by the risk of cardiac and pulmonary complications, which even led to decreased survival in a randomised study, when a higher tumor dose was administered \[1\]. Radiation induced pulmonary and cardiac toxicity are the most important late side effects after thoracic radiotherapy \[2-4\]. The aim of this study is to reduce the radiation dose of heart (and lungs) in order to reduce the toxicity risk. In recent years, the active breathing control (ABC) technique has been introduced in the radiotherapy for left sided breast cancer patients, to minimize the radiation dose to the heart. These patients are irradiated in the inspiration phase, in which the distance between the heart and the breast is largest, while the lungs extend. Breath hold might also be beneficial for radiotherapy of esophageal and lung tumors. For these patients the expiratory phase might theoretically be more beneficial to reduce the heart dose. However, the inspiration phase might be better for the dose to the lungs, which consequently allows cardiac dose reduction.
