Prognostic Value of 18F-FDG Standard Uptake Value by Integrated PET/CT in the Staging of Malignant Pleural Mesothelioma
2012
Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor with generally disappointing results in terms of survival, however, there are occasional long-term survivors probably due to the biologic characteristics of the disease. Standard uptake value (SUV) of [18F] Fluorodeoxyglucose (FDG) evaluated by photon emission tomography (PET) is now widely accepted as an indicator of biologic behavior in several malignancies. The aim of this study was to verify whether SUVmax and SUVmean are inversely associated with the prognosis of patients with MPM and whether there was a correlation between grading/disease stage and SUV value. Patients with histologically proven MPM underwent integrated PET and computed tomography (CT) scanning. Patients fasted and received 5.18 MBq of FDG per kilogram of body weight. Based on the maximum Chi-Square method, a SUVmax of 4.21 (range: 2.30–14.74) and a SUVmean of 2.78 (range: 1.80–7.00) were used to classify patients as having a good or poor prognosis, respectively.
