Radio-guided surgery a safe and simple way to remove potentially cancerous nodules in the lung
Date:2/26/2011

r medical tests. After injection, they used another CT scan and a technique called gamma scintigraphy --which visualizes the gamma radiation being emitted by the radioactive isotope-- to confirm precise staining of the nodule.

During surgery to remove the nodule, the researchers used a gamma detector probe to ensure they had removed all the radio-labeled tissue.

The researchers found that the technique was able to localize nodules in all 19 patients. On average it took 6 minutes to detect the nodule with the gamma probe.

Further analysis of the tissue that had been removed showed that it was a primary lung cancer in 8 cases, and a secondary lesion in 4 cases. The remaining 7 patients were found to have benign nodules. There were no complications during or after surgery.

This study shows that radio-guided surgery is a safe and simple technique for localizing single pulmonary nodules, Dr Terzi said. "Radio-guided thoracoscopy seems to be an effective procedure with fewer complications and failures than other techniques."

Commenting on the study, Dr Eric Lim, Consultant Thoracic Surgeon, Royal Brompton Hospital and Senior Lecturer, National Heart and Lung Institute, Imperial College, London, who was not involved in the study, said: "Dr Bertolaccini reports an innovative method to localize nodules that can be difficult for the surgeon to identify during routine surgery."

"This technology supports the current practice of video-assisted thoracoscopic lung resection as surgeons continuously strive to reduce incision size, pain and length of stay to increase the acceptability of surgery for lung cancer," said Dr Lim.
