概括
在术前化疗后PET扫描的代谢反应预测了胰腺癌的结果. 显示最大标准化摄入值 (SUVmax) 显著下降的患者的生存率更好,复发率更低.
科学领域:
- 在瘤学瘤学.
- 核医学是一种核医学.
- 无线电学 (Radiomics) 是一种放射学.
背景情况:
- 胰腺癌的治疗需要可靠的标记物来确定手术前化疗的有效性.
- 目前评估治疗反应的指标有限.
- 使用-18-氧化葡萄糖正子发射断层扫描 (FDG-PET) 的代谢反应评估提供了一个潜在的预后工具.
研究的目的:
- 为了评估代谢反应的预后值,通过FDG-PET的最大标准化吸收值 (SUVmax) 的变化来评估,在接受手术前化疗的胰腺癌患者中.
- 为了确定代谢反应是否可以预测整体存活率,复发率和手术后的病理完整反应.
主要方法:
- 分析了一组210名胰腺癌患者的队列,这些患者在2013年至2022年期间接受了手术前化疗和治愈性手术.
- 根据SUVmax的百分比变化,使用最大选择的等级统计数据对代谢反应进行了分类:响应者 (>75%的减少),稳定疾病 (15%-75%的减少) 和非响应者 (≤15%的减少).
主要成果:
- 与稳定疾病 (66.7%,51.0个月) 和非响应者 (11.6%,32.0个月) 相比,代谢响应者 (15.7%) 的平均整体存活时间 (83.0个月) 显着更长.
- 代谢反应是较低复发率 (HR 0.46) 和实现病理完整反应 (OR 13.39) 的更高几率的独立预测因素.
结论:
- 在术前化疗期间FDG-PET评估的代谢反应是胰腺癌切割后预后的有价值预测指标.
- SUVmax的变化提供了关于治疗有效性和残留瘤状况的关键信息,有助于患者管理.

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...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
