CPC-039 Lung Cancer, Radiation Therapy & PET
As we continue our discussion of lung cancer, I want to cover how radiation therapy and PET are becoming linked. I’ll discuss the three key volumes used for any plan, the most important of which is the Gross Tumor Volume (GTV) that the therapist delineates using imaging. In lung cancer, PET can have a particular influence on the size of the GTV, either by increasing or decreasing this volume. For example, PET can detect regional lymph nodes in non-small cell lung cancer patients.
