目的本研究旨在评估2-[18F]氟丙酸([18F]FPA)在前列腺癌(PCa)PET成像中的潜在价值,并探讨PCa模型中[18F]FPA积累与脂肪酸合酶(FASN)水平之间的关系。报道首例PCa患者的[18F]FPA PET研究结果。 方法选择高FASN表达的LNCaP、PC-3细胞系和低FASN表达的DU145细胞系进行细胞培养。在LNCaP、PC-3和DU145肿瘤中进行[18F]FDG和[18F]FPA的APET成像比较。此外,在这些模型中使用奥利司他进行体内抑制实验。在一项人体PET研究中,对术前PCa患者进行了[18F]FPA PET和[18F]FDG PET检查。结果LNCaP和PC-3肿瘤中[18F]FPA的摄取高于[18F]FDG(P<0.05和P<0.05),但在DU145肿瘤中较低(P<0.05)。用奥利司他治疗后,LNCaP、PC-3和DU145肿瘤中[18F]FPA的积累(%ID/g)分别减少了27.6%、40.5%和11.7%。在第一位 PCa 患者中,[18F]FPA 显示出比 [18F]FDG 更高的放射性摄取。结论 PCa 模型中的 [18F]FPA 摄取可能随脂肪酸合酶活性而变化,并且在施用单一 FASN 抑制剂后可能会减少,尽管活性不是直接测量的。 [18F]FPA 似乎是一种潜在的广谱 PET 显像剂,并且可以作为诊断人类 PCa 的有价值的工具。
PurposeThis study aimed to evaluate the potential value of 2-[18F]fluoropropionic acid ([18F]FPA) for PET imaging of prostate cancer (PCa) and to explore the relationship between [18F]FPA accumulation and fatty acid synthase (FASN) levels in PCa models. The results of the first [18F]FPA PET study of a PCa patient are reported.ProceduresThe LNCaP, PC-3 cell lines with high FASN expression, and DU145 cell lines with low FASN expression were selected for cell culture.APET imaging comparison of [18F]FDG and [18F]FPA was performed in LNCaP, PC-3, and DU145 tumors. Additionally,in vivoinhibition experiments in those models were conducted with orlistat. In a human PET study, a patient with PCa before surgery was examined with [18F]FPA PET and [18F]FDG PET.ResultsThe uptake of [18F]FPA in the LNCaP and PC-3 tumors was higher than that of [18F]FDG (P<0.05 andP<0.05), but was lower in DU145 tumors (P<0.05). The accumulation (% ID/g) of [18F]FPA in the LNCaP, PC-3, and DU145 tumors decreased by 27.6, 40.5, and 11.7 %, respectively, after treatment with orlistat. The [18F]FPA showed higher radioactive uptake than [18F]FDG in the first PCa patient.ConclusionsThe [18F]FPA uptake in PCa models may be varies with fatty acid synthase activity and could be reduced after administration of a single FASN inhibitor, albeit the activity that is not measured directly. The [18F]FPA seems to be a potential broad-spectrum PET imaging agent and may serve as a valuable tool in the diagnosis of PCa in humans.
