PET Scan in Lung Cancer Follow-up
Can you address the use of PET scans for follow up after surgery?
Charles B. Simone II, MD, Radiation Oncologist at Penn Medicine, responds:
There are no recommendations that are widely agreed upon for how to follow patients once they have completed therapy for lung cancer. The options are to use chest x-rays, CT scans, or CT-PET scans. Most physicians treating lung cancers will follow patients more closely (every 3-6 months) for the first 2 years after treatment, when they are at the highest risk for recurrence, but patients will often continue to be followed with life-long annual surveillance thereafter. CT scans are more sensitive for detecting a recurrence or new cancer than chest x-rays. Most guidelines and experts recommend surveillance with CT scans and not PET or PET/CT scans. PET/CT scans, however, can be used to evaluate any abnormality that may be revealed by the CT scan.
