After Stereotactic Body Radiotherapy PET Scans Track Small Tumors

Readily available CT screening for lung cancer is increasing the discovery of small, primary lung cancers. For many, a radiation technique called stereotactic body radiotherapy presents a less invasive treatment option to surgery that is typically offered to non-surgical candidates. Currently there is great interest in evaluating this approach in surgical candidates, but researchers have yet to identify an early method to determine the effectiveness in treatment which is vital. In a study presented at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles, researchers presented data showing metabolic response monitored by FDG PET may be an early surrogate for local treatment failure which may allow timely salvage surgery if deemed necessary.
