概括
前列腺癌可以在放射学上进展,即使PSA水平无法检测. 像PSMA PET/CT这样的先进成像对于早期检测和管理至关重要,无论PSA状态如何.
科学领域:
- 在瘤学瘤学.
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
背景情况:
- 尽管前列腺特异性抗原 (PSA) 水平无法检测,但前列腺癌 (PCa) 的进展可能会发生.
- 在PCa中,放射性疾病进展 (rDP) 需要进一步调查,特别是在低PSA的背景下.
- 需要澄清PSMA PET/CT在识别无法检测PSA的rDP中的实用性.
研究的目的:
- 确定前列腺癌 (PCa) 患者的PSMA PET/CT放射性疾病进展 (rDP) 的频率和特征.
- 分析PSA零rDP的临床影响,包括进展到抗割PCa和整体存活率.
- 评估rDP地点与整体存活率 (OS) 之间的关联.
主要方法:
- 梅奥诊所PSMA PET前列腺癌注册表对rDP和无法检测的PSA患者的分析.
- 通过活检或治疗反应确认疾病进展.
- 估计使用卡普兰-梅尔法和日志等级测试进行组比较的整体存活 (OS).
主要成果:
- 12% (257/2141) 的患者在2021-2023年期间表现出PSA零rDP.
- 61%的人最初患有局部性疾病,39%的人患有新发转移性疾病.
- 内脏转移显著与较差的生存状况相关 (p < 0.0001).
结论:
- 前列腺癌患者经常发展转移性疾病,即使PSA值无法检测.
- 建议定期进行高级成像,如PSMA PET/CT,不论PSA水平如何,以及时检测进展.

7.9K
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 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...
