概括
FDG PET/CT扫描和血液测试可以帮助预测头癌 (HNSCC) 中的HPV状况. 特定的成像指标,如瘤代谢体积 (MTV) 和瘤与肝脏的比率 (TLRmax),在HPV阴性患者中较高.
科学领域:
- 在瘤学瘤学.
- 核医学是一种核医学.
- 生物标志物 生物标志物
背景情况:
- 人类乳头瘤病毒 (HPV) 状态是头部和部状细胞癌 (HNSCC) 的关键预后因素.
- 准确确定HPV状态对于指导治疗策略和预测患者结果至关重要.
- 在临床实践中,预测HPV状况的非侵入性方法非常可取.
研究的目的:
- 评估[18F]FDG PET/CT成像参数和血液学标记在确定HNSCC患者HPV状况中的有用性.
- 确定特定的PET/CT指标和血液检测结果,可以作为HPV负性的独立预测指标.
主要方法:
- 从106名HNSCC患者的临床和诊断数据的回顾性分析 (26.4%的HPV阳性,73.6%的HPV阴性).
- 评估半定量[18F]FDG PET/CT参数,包括SUVmax,SUV平均值,SUV总值,代谢瘤体积 (MTV),总损伤糖解 (TLG),以及瘤与肝脏的比率 (TLRmax,TLR平均值,TLRTLG).
- 血液学变量的评估:白细胞 (WBC),淋巴细胞 (LYMPH),中性细胞 (NEU),单细胞 (MON),血小板 (PLT) 和各种比率 (NRL,LMR,PLR,MLR). 使用了统计和人工神经网络分析.
主要成果:
- 在HPV阳性和HPV阴性组之间观察到主要瘤MTV和TLRmax的显著差异,在HPV阴性组的值较高.
- 阴性HPV患者的中性粒细胞数量 (NEU),中性粒细胞百分比 (NEU%) 和中性粒细胞与淋巴细胞比率 (NRL%) 显著增加.
- 接收器操作特征 (ROC) 分析确定了几个FDG PET/CT参数 (SUVmax,TotalSUV,MTV,TLG,TLRmax,TLRTLG) 和口腔位定位作为HPV负性的独立预测因素.
结论:
- 从原发性瘤的FDG PET/CT成像中获得的半定量参数是HNSCC中HPV负性的有价值的独立预测指标.
- 这些成像生物标志物,与血液学参数一起,可以支持在HNSCC患者中非侵入性确定HPV状态.
- 需要进一步的前性研究来验证这些发现,并将其纳入临床决策.

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...
