- 涉及34名IIIB期非小细胞肺癌 (NSCLC) 患者.
- 使用传统的[18F]化氧糖 (FDG) 阳子发射断层扫描 (PET) 标准化吸收值 (SUV) 分析和化学辐射前后骨糖代谢的新型网络分析.
主要成果:
- 传统的肺瘤SUV分析没有预测NSCLC患者的存活率 (p = 0.23-0.35).
- 在化学辐射前对骨糖代谢的网络分析显著预测了患者的生存率 (p = 0.0003),确定了不同的幸存者群.
- 化学辐射导致了集群同质化和骨代谢网络的预测价值的丧失 (p = 0.77).
结论:
- 天生的,治疗前的骨葡萄糖代谢网络预测NSCLC患者的生存率.
- 适应后的治疗后网络失去了预测价值,突出了骨在先天免疫力和全身葡萄糖调节中的作用.
- 骨代谢的网络分析是一个优越的预后工具,与传统的SUV PET分析对NSCLC相比.

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...

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...
