Françoise Mornex, MD, PhD, of Claude Bernard University, Lyon, France, discusses recent developments in radiotherapy techniques for lung cancer, including intensity-modulated radiotherapy (IMRT) and stereotactic radiotherapy. Speaking at the European Lung Cancer Congress (ELCC) 2019, held in Geneva, Switzerland, Prof. Mornex reports that IMRT is especially promising as the method allows the delivery of optimal doses of radiation to the tumor while sparing other, healthy organs.
