概括
间隔压缩化疗 (ICC) 对局部化的尤文肉瘤在10年内显示出比标准化疗持续的生存优势. 这种方法改善了无事件和整体存活率,而没有增加二次癌症.
科学领域:
- 儿科瘤学 儿科瘤学
- 医学瘤学 医学瘤学
- 临床试验 临床试验
背景情况:
- 临床试验结果通常随着终点的成熟而顺序报告.
- 更新的分析为治疗的有效性和安全性提供了关键的长期数据.
- 以前关于AEWS0031的报道显示,间隔压缩化疗 (ICC) 的生存益处.
研究的目的:
- 评估与标准时间化疗 (STC) 相比,ICC的生存优势的长期 (10年) 维持.
- 为了评估二次恶性瘤 (SMNs) 的发病率,在接受ICC治疗的患者与STC治疗.
- 为了确定受益于局部尤文肉瘤中ICC的患者子组.
主要方法:
- 从儿童瘤组研究AEWS0031.3的长期结果的分析.
- 随机分配568名符合条件的患者接受ICC (每2周一次化疗) 或STC (每3周一次化疗).
- 评估10年无事件生存率 (EFS),总生存率 (OS) 和SMN的累积发病率.
主要成果:
- 10年EFS是70%的ICC与STC (P=.03) 的61%相比.
- 10年后的生存率为ICC的76%,与STC的69%相比 (P=.04).
- 在ICC和STC组之间,SMN的10年累积发病率没有显著差异 (P=.5).
结论:
- 长期的随访证实,与STC相比,ICC与局部Ewing肉瘤中优越的EFS和OS有关.

Treatment Resistant Cancers
3.3K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
