Françoise Mornex, MD, PhD, of Claude Bernard University, Lyon, France, talks about the use of thoracic irradiation in patients with oligometastatic non-small cell lung cancer (NSCLC). Speaking at the European Lung Cancer Congress (ELCC) 2019, held in Geneva, Switzerland, Prof. Mornex reports that currently, there is little data to support the efficacy of this method and so more research is required to confirm the promises of using thoracic irradiation for oligometastatic NSCLC.
