概括
巩固性辐射疗法 (RT) 对晚期霍奇金淋巴瘤患者实现完全反应而没有无进展生存益处. 这一发现基于对两项试验的二次分析,表明RT在这个患者群体中没有益处.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 临床试验 临床试验
背景情况:
- 巩固性放射治疗 (RT) 在患有庞大疾病的高级霍奇金淋巴瘤中的作用仍然不确定.
- 以前的随机对照试验 (RCT) 没有证明化疗后巩固性RT的益处.
- 在之前的研究中,有限的样本大小可能降低了检测小益处的统计能力.
研究的目的:
- 评估在患有晚期霍奇金淋巴瘤和体积较大的疾病,达到完全代谢反应的患者中整合性RT的疗效.
- 为了比较无进展生存期 (PFS) 在被随机分配到没有RT的患者和随机分配到最初批量部位的RT.
主要方法:
- 使用重建的患者数据对两个第三阶段RCT (GITIL/FIL HD0607和FIL HD0801) 的二次分析.
- 进行了治疗意图 (ITT) 和每协议 (PP) 分析.
- 在使用日志级别测试的组之间进行了无进展生存 (PFS) 的比较.
主要成果:
- 总共分析了412名患者 (ITT) 和373名患者 (PP).
- 五年ITT PFS为没有RT和RT组的90.1% (P = .81).
- 五年PP PFS为没有RT的90.9%,RT的92.9% (P = .31),在体积较大的疾病亚组中没有发现显著差异.
结论:
- 巩固性RT到最初的庞大的结节部位不会在晚期霍奇金淋巴瘤患者中改善PFS,这些患者在化疗后具有完全的代谢反应.
- 这些发现表明,RT在这个特定的患者群体中与PFS益处无关.
- 这项分析提供了进一步的证据,证明RT在治疗大型霍奇金淋巴瘤中的作用.

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
