Multidisciplinary Postoperative Validation of 18 F-FDG PET/CT Scan in Nodal Staging of Resected Non-Small Cell Lung Cancer.

This analysis showed the significance of extracapsular tumor invasion, which causes an inflammatory reaction, on LNM, which is probably responsible for preoperative false-positive findings. In conclusion, PET/CT scans are very effective in identifying patients without tumors. Furthermore, it is highly probable that patients with negative findings are free of disease.
