概括

-18-氧葡萄糖正子发射断层扫描/计算机断层扫描 (18F-FDG PET/CT) 显著改善了瘤划分和分期的头部和部状细胞癌 (HNSCC) 患者接受放射治疗. 这种增强的成像允许更精确的辐射规划,可能改善治疗结果.

科学领域:

在瘤学瘤学.
放射疗法是一种放射治疗.
医疗成像医学成像

背景情况:

精确的分期和瘤划分对于头部和部状细胞癌 (HNSCC) 的有效放射治疗 (RT) 至关重要.
基于计算机断层扫描 (CT) 的RT是标准的,但18F-FDG PET/CT提供了对初级和结节疾病的卓越检测.

研究的目的:

调查18F-FDG PET/CT对HNSCC患者的RT规划的影响.
将仅使用CT生成的RT计划与PET/CT数据进行比较.

主要方法:

一项针对51名HNSCC患者进行的前性研究,这些患者接受了与西斯普拉丁的激烈体积调节弧RT.
每位患者创建了两个RT计划:一个仅使用CT数据,另一个使用PET/CT数据.
分析和比较了计划目标体积 (PTV) 和剂量-体积直方图.

主要成果:

在11.8% (T阶段) 和33.3% (N阶段) 的患者中,PET/CT改变了TNM分期.
远程转移在9.8%的患者中被发现,影响了治疗政策.
在37.2%的患者中,PET/CT规划改善了原发性瘤PTV覆盖率 (PTV4),在33.3%的患者中改善了节点PTV (PTV2),剂量向目标体积递送显著改善.

结论:

18F-FDG PET/CT增强了HNSCC中原发性瘤和淋巴结的点划分.
在代谢活跃的病变中,PET/CT可促进剂量升级,并识别隐藏的远程转移.
集成PET/CT使得HNSCC的个人化和潜在的更有效的RT策略成为可能.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
