概括
布里甘蒂2019名图表对于检测前列腺癌患者的淋巴结转移而不是最佳的,前列腺癌患者的PSMA-PET扫描结果为负. 需要更准确的方法来识别那些可以从进一步治疗中受益的患者.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 在瘤学瘤学.
- 核医学就是核医学.
背景情况:
- 在急性前列腺切除术 (RP) 期间,根据淋巴结 (LN) 转移风险推进行骨盆淋巴结解剖 (ePLND).
- ePLND带有潜在的副作用,促使在改进成像的背景下对诊断工具进行评估.
- 术前[68Ga]Ga-PSMA-11PET扫描越来越多地用于评估RP之前的转移.
研究的目的:
- 为了评估布里甘蒂2019年名图的表现在前列腺癌患者的当代队列中,前手术前PSMA-PET扫描结果为负.
- 为了评估nomogram在预测淋巴结转移中的准确性.
- 在这个患者群体中确定与淋巴结转移相关的临床参数.
主要方法:
- 包括中等和高风险前列腺癌患者接受RP和ePLND的术前阴性[68Ga]Ga-PSMA-11 PET.
- 通过ROC分析和临床参数的后勤回归来评估nomogram的准确性.
- 在假阴性PSMA-PET扫描患者的样本上进行了AR和PSMA的免疫组织化学 (IHC).
主要成果:
- 该研究包括108名患者 (28%中等,72%高风险);12人患有隐藏的LN转移.
- 布里甘蒂2019年号码表显示准确度为0.62.
- [68Ga]Ga-PSMA-11 PET具有89%的负预测值 (NPV).
- 数字直肠检查 (DRE) 和癌症核心的百分比与LN转移显著相关 (P<0.05).
结论:
- 布里甘蒂2019名图表对于检测阴性淋巴结转移在前列腺癌患者的阴性PSMA-PET扫描是不理想的.
- 虽然负的PSMA-PET可能允许对ePLND的值略高,但需要更精确的患者选择方法.
- 在PSMA-PET成像时代,ePLND的治疗效益与诊断效益需要重新评估.

Positron Emission Tomography
4.2K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
93
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...
