The objective of this study is to systematically review the role of positron emission tomography (PET) and PET/computed tomography (PET/CT) with Fluorine-18-Fluorodeoxyglucose (FDG) in patients with osteosarcoma (OS).
A comprehensive literature search of published studies through October 10(th), 2012 in PubMed/MEDLINE, Embase and Scopus databases regarding whole-body FDG-PET and FDG-PET/CT in patients with OS was performed.
We identified 13 studies including 289 patients with OS. With regard to the staging and restaging of OS, the diagnostic performance of FDG-PET and PET/CT seem to be high; FDG-PET and PET/CT seem to be superior to bone scintigraphy and conventional imaging methods in detecting bone metastases; conversely, spiral CT seems to be superior to FDG-PET in detecting pulmonary metastases from OS.
Metabolic imaging may provide additional information in the evaluation of OS patients. The combination of FDG-PET or FDG-PET/CT with conventional imaging methods seems to be a valuable tool in the staging and restaging of OS and may have a relevant impact on the treatment planning.
本研究旨在系统地回顾氟代脱氧葡萄糖(FDG)正电子发射断层扫描(PET)和 PET/计算机断层扫描(PET/CT)在骨肉瘤(OS)患者中的作用。
通过 PubMed/MEDLINE、Embase 和 Scopus 数据库对截至 2012 年 10 月 10 日发表的关于全身 FDG-PET 和 FDG-PET/CT 在 OS 患者中的应用的研究进行了全面的文献检索。
我们共确定了 13 项研究,包括 289 名 OS 患者。在 OS 的分期和再分期方面,FDG-PET 和 PET/CT 的诊断性能似乎较高;FDG-PET 和 PET/CT 在检测骨转移方面似乎优于骨闪烁扫描和常规影像学方法;相反,螺旋 CT 在检测 OS 的肺转移方面似乎优于 FDG-PET。
代谢成像可能为 OS 患者的评估提供额外信息。FDG-PET 或 FDG-PET/CT 与常规影像学方法的结合似乎是 OS 分期和再分期的一种有价值的工具,并且可能对治疗计划产生相关影响。
