Diagnostic and prognostic values of FDG-PET in patients with non-small cell lung cancer

PurposeThe aim of this study was to address the efficacy of 2-[F-18]-Fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) in the staging of non-small cell lung cancer (NSCLC) and in prognostic prediction in patients with NSCLC.MethodsForty-four patients (26 males, 18 females) were analyzed.ResultsAccurate staging was obtained by addition of FDG-PET. Multivariate analysis indicated that the standardized uptake value of the primary tumor was the most significant prognostic factor for disease-free survival (P=.0073).ConclusionFDG-PET is useful for the diagnosis of NSCLC and for prognostic prediction in patients with NSCLC.
