18F-FLT MicroPET评估顺铂对A549肺癌早期疗效反应的研究
18F-FLT MicroPET Imaging of Early Anti-tumor Response to Cisplatin on Lung Cancer
摘要
Abstract
In order to investigate the feasibility of 18F-FLT MicroPET in the early efficacy of the antineoplastic drug. Twelve A549 lung carcinoma-loaded mice were randomly divided into 2 groups(control and treatment group, n=6 in each group). Cisplatin (DDP, 25 mg/ kg) and saline were injected intragastricaly everyday to the treatment and control group, respectively. Tumor volume and weight were detected everyday and 18F-FLT MicroPET scans were performed at 0, 2, 5, 9, 14 d. The MicroPET results showed that after the second ad-ministration, the tumor uptake of treatment group decreased 21. 28%, from (4. 91 ± 0. 71)%ID/g to (3. 87±0. 61)%ID/g, while tumor volume was significantly decreased until 9 d (P<0. 01). Compared with traditional method, MicroPET can detect much earlier and more accurate efficacy of antitumor agents.关键词
