ScienceDaily (Nov. 6, 2009) — A rapid decline in metabolic activity on a PET scan after radiation therapy for non-small cell lung cancer is correlated with good local tumor control, according to a study presented by researchers at Thomas Jefferson University Hospital at the 51st ASTRO Annual Meeting.
In addition, the researchers also found that the higher the metabolic activity and tumor size on a PET scan before treatment, the more likely a patient is to die from lung cancer.
"PET scanning is an emerging tool of molecular imaging in lung cancer, in contrast to CT scans and MRI scans which are anatomic imaging," said Maria Werner-Wasik, associate professor of Radiation Oncology at Jefferson Medical College of Thomas Jefferson University, and the study's lead author. "It has become an important tool in the evaluation of lung cancer staging and evaluation of treatment response."
