概括
通过FDG PET扫描测量干的代谢瘤体积 (MTV) 是治疗免疫疗法和化疗的高级非小细胞肺癌 (NSCLC) 患者无进展生存 (PFS) 和整体生存 (OS) 的重要预测指标.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 核医学是一种核医学.
背景情况:
- 晚期非小细胞肺癌 (NSCLC) 是一个重大的治疗挑战.
- 免疫检查点抑制剂 (ICI) 与基于的化疗相结合,代表了高级NSCLC的标准一线治疗.
- 预后生物标志物对于分层患者和个性化治疗策略至关重要.
研究的目的:
- 在接受一线ICI和化疗的晚期NSCLC患者中,评估18F-氧糖 (FDG) 定子发射断层扫描 (PET) 参数的预后值.
- 评估在初级瘤和干转移中代谢瘤负担的重要性.
主要方法:
- 在一线ICI治疗之前,对70名III/IV期NSCLC患者进行了基线FDG PET/CT的回顾性分析.
- 对干病变的SUVmax,代谢性瘤体积 (MTV) 和总损伤糖解 (TLG) 的量化.
- 使用生存分析,PET参数与无进展生存率 (PFS) 和总生存率 (OS) 的相关性.
主要成果:
- 较高的干MTV和TLG与较差的表现状态有关 (PS ≥2).
- 单变量分析显示PS,MTV-干和TLG-干显著预测了PFS和OS.
- 多变量分析确定PS和MTV-干是PFS和OS的独立预测因素.
- 下部MTV-干 (<225.81) 与明显更长的PFS和OS相关 (P <0.001).
- SUVmax-torso与生存结果没有显著的关联.
结论:
- 基于干的代谢瘤体积 (MTV-干) 是先进的NSCLC患者在一线ICI和化疗中PFS和OS的强有力的独立预测器.
- FDG PET衍生代谢瘤负担评估有助于该患者组的预后分层.
- 可以将MTV-torso集成到临床决策中,用于治疗规划和患者管理.

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 being...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
