Radiation dose to heart base linked with poorer survival in lung cancer patients

Advances in radiotherapy (RT) have allowed an increased proportion of lung cancer patients to be treated curatively. High doses delivered to critical thoracic organs can result in excess mortality with tolerance doses poorly defined. This work presents a novel method of identifying anatomical dose-sensitive regions within the thorax.A high-resolution, normal-tissue dosimetric analysis was performed to identify regions in the heart that correlate...
