概括
将6个月的雄激素抑制疗法 (AST) 添加到70 Gy 3D-CRT (3D-CRT) 符合辐射治疗中,显著改善了局部性前列腺癌患者的生存率. 这种组合疗法可以降低前列腺癌的死亡率,并减少后期救援治疗的需要.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
背景情况:
- 高度局部性前列腺癌的管理通常涉及70 Gy辐射疗法与3年的雄激素抑制疗法 (AST),但长期的AST有不良影响.
- 调查AST较短的持续时间对于平衡治疗疗效和患者福祉至关重要.
研究的目的:
- 在临床局部性前列腺癌患者中,评估单独3D-CRT和3D-CRT与6个月AST相结合的3D-CRT的生存益处.
主要方法:
- 一项前性随机对照试验,涉及206名局部前列腺癌患者.
- 患者随机分配,接受单独70 Gy 3D-CRT (104名患者) 或70 Gy 3D-CRT与6个月的AST (102名患者).
- 关键的资格标准包括PSA≥10 ng/mL,格里森得分≥7,或放射性前列腺外疾病.
主要成果:
- 平均随访时间为4.52年后,3D-CRT加AST组的整体存活率显著提高 (P=.04) 和前列腺癌特异性死亡率降低 (P=.02).
- 在组合治疗组中,无救援AST的存活率明显高于组合治疗组 (P=.002).
- 使用3D-CRT加AST的5年生存率为88%,仅使用3D-CRT为78%;无救援AST的5年生存率分别为82%和57%.
结论:
- 将6个月的AST添加到70 Gy 3D-CRT中,为临床局部性前列腺癌患者提供了显著的整体生存益处.
- 这种较短的AST持续时间有效地提高了治疗结果,同时可能减轻与长期安德روج因抑制相关的长期副作用.

Randomized Experiments
6.3K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
732
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...
