概括
-131前列腺支架疗法 (PB) 为低风险和中等风险前列腺癌提供了出色的生化控制. 患者报告的生活质量结果与立体性身体放射疗法相当,支持PB考虑.
科学领域:
- 在瘤学瘤学.
- 辐射疗法 辐射疗法
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
背景情况:
- 使用-131 (Cs-131) 的低剂量率 (LDR) 前列腺支架疗法 (PB) 是前列腺癌的治疗选择.
- 将PB结果与其他放射治疗方法进行比较对于治疗选择至关重要.
研究的目的:
- 使用已发表的数据,比较Cs-131 PB单疗与立体体辐射疗法 (SBRT) 的结果.
- 评估患者报告的Cs-131 PB后的生活质量.
主要方法:
- 对138名用Cs-131 PB单疗法治疗的患者进行分析,随访至少5年.
- 展望收集扩大前列腺癌指数复合 (EPIC) 问卷.
- 与放射治疗瘤组 (RTOG) 0938和PACE-B试验的数据进行比较.
主要成果:
- 尿功能下降在Cs-131 PB中为43%,而在RTOG 0938.3中为41.3%.
- 在2年后,与PACE-B (32%, 33%) 相比,Cs-131 PB在尿路领域显示出最小的临床重要差异 (26.4%的尿失禁,40.7%的阻塞性/刺激性).
- 五年生化无疾病生存率 (bDFS) 为Cs-131 PB的97.8%,而RTOG 0938的91.3%和PACE-B的95.8%.
结论:
- Cs-131 PB单一治疗显示出对低风险和中等风险前列腺癌的良好生化控制.
- 患者报告的尿路和肠道生活质量变化很小,与SBRT相比.
- 考虑到患者的方便性和资源的可用性,Cs-131 PB是一种可行的治疗选择.

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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
