Abstract:

Background: In this study, we evaluated the activity of IPF on preoperative PET in patients who underwent lung cancer surgery and attempted to identify high-risk patients who might develop postoperative Acute Exacerbation (AE) of IPF. Methods: The pulmonary uptake of Fluorodeoxyglucose (18F-FDG) was quantified at six sites (left and right sides of the upper, middle, and lower lobes), and AE of IPF after lung cancer surgery was examined. Results: UIP patients had a significantly higher FDG distribution in the right upper lobe than other IPs (p<0.05). Seven patients who were all UIP developed AE after lung resection, their FDG accumulation was high in bilateral upper lobe (p<0.05), in UIPs. Conclusion: The widely distributed pulmonary uptake of 18F-FDG on preoperative PET might be an etiologic factor predicting postoperative AE in UIP patients with lung cancer.
