Abstract: Objective To explore whether myocardial glucose metabolism is altered and its related factors in newly diagnosed patients with lung adenocarcinoma (LAD) who underwent fluorine-18 fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT). Methods From our 18F-FDG PET/CT imaging database, 182 patients with newly diagnosed LAD and 45 non-oncologic subjects with matched age and sex were retrospectively analyzed. The uptake of 18F-FDG in left ventricular (LV) myocardium, arterial wall, epicardial adipose tissue (EAT), spleen, and bone marrow were compared between the two groups. Multiple Logistic regression analysis was used to identify significant factors related with the high uptake of 18F-FDG in left ventricle of LAD. Results LAD patients had higher uptake of 18F-FDG in left ventricle than that of non-oncologic patients (P=0.05), whereas no significant difference of 18F-FDG uptake was found in the arterial wall, EAT, spleen, or bone marrow between the two groups. The activity of EAT was independently related to the high LV 18F-FDG uptake in LAD before antineoplastic therapy. Conclusion Myocardial glucose metabolism was increased in patients with LAD before antineoplastic therapy. The activity of EAT was an independent factor for prediction of the high LV 18F-FDG uptake in LAD.
