| 内容記述 | Objective: A novel radiopharmaceutical, 4'-[methyl-(11)C]thiothymidine ((11)C-4DST), has been developed as an in vivo cell proliferation marker based on the DNA incorporation method. The purpose of this study was to evaluate (11)C-4DST uptake in patients with newly diagnosed glioma and to correlate the results with proliferative activity and tumor grade, in comparison with L-[methyl-(11)C]-methionine ((11)C-MET). | |||||

| 内容記述 | Methods: Investigations of (11)C-4DST and (11)C-MET PET/CT were performed retrospectively in 23 patients with newly diagnosed glioma. The maximum standardized uptake value (SUVmax) for tumor (T) and the mean SUV for normal contralateral hemisphere (N) were calculated, and the tumor-to-normal (T/N) ratio was determined. Metabolic tumor volume (MTV) was defined as the volume with a threshold of 40% of the SUVmax. Proliferative activity as indicated by the Ki-67 index was estimated in tissue specimens. | |||||

| 内容記述 | Results: Of 23 gliomas examined, (11)C-4DST PET/CT and (11)C-MET PET/CT detected 20 and 22, respectively. Linear regression analysis between (11)C-4DST and (11)C-MET indicated a weak correlation for SUVmax (r = 0.54, P < 0.008), for T/N ratio (r = 0.56, P < 0.006), and for MTV (r = 0.60, P < 0.003). Linear regression analysis indicated a weak correlation between (11)C-4DST and Ki-67 index for SUVmax (r = 0.46, P < 0.03), for T/N ratio (r = 0.43, P < 0.05), and for MTV (r = 0.68, P < 0.001) and between (11)C-MET MTV and Ki-67 index (r = 0.43, P < 0.04). Using (11)C-4DST, there was a significant difference in SUVmax between grades II and IV (P < 0.03) and in MTV between grades II and IV (P < 0.009) and grades III and IV (P < 0.02). Using (11)C-MET, there was a significant difference in SUVmax (P < 0.009) and T/N ratio (P < 0.02) between grades II and IV and in MTV between grades II and IV (P < 0.03) and grades III and IV (P < 0.02). | |||||

| 内容記述 | Conclusion: (11)C-4DST PET/CT is feasible for imaging of brain gliomas, as well as (11)C-MET PET/CT. Especially, it showed the highest correlation coefficient between (11)C-4DST MTV and Ki-67 index in newly diagnosed gliomas. Keywords: 11C-4DST; 11C |
