F-18 fluorodeoxyglucose-positron emission tomography ([18F]FDG PET), a functional imaging modality, can be used to measure tumor cell metabolism. Thus, in this study, we hypothesize that there exist correlations between EGFR mutation status and [18F]FDG uptake of advanced lung adenocarcinoma. Methods From May 2004 to April 2008, patients with stage IIIB or IV lung adenocarcinoma who underwent [ 18F]FDG PET and EGFR mutation analysis before receiving any treatment were eligible to participate in this study. The association of EGFR mutation status with patient characteristics and the SUVMAX from the [ 18F]FDG PET was evaluated. Multivariate logistic regression analysis was used to analyze predictors of EGFR mutations. Results Seventy-seven lung adenocarcinoma patients were included in this study. EGFR mutations were identified in 49 (64%) of the patients. The [18F]FDG uptake was significantly higher in EGFR-mutant (mean SUVMAX = 10.5 ± 4.7) than wild-type (8.0 ± 3.3) lung adenocarcinoma patients (P = 0.008). The median SUVMAX was 9.5, and patients with an SUVMAX 9.5 were more likely to harbor EGFR mutations (P = 0.009). In the multivariate analysis, an SUVMAX 9.5 remained a statistically significant predictor of EGFR mutations (P = 0.005). Conclusions Among Asian patients with advanced lung adenocarcinoma, those with higher SUVMAX on the [ 18F]FDG PET are more likely to carry EGFR mutations. ? 2008 Humana Press Inc. |
