概括
没有放射治疗的新辅助化疗 (NAC) 在约一半高风险局部晚期直肠癌 (LARC) 患者中显示出具有临床意义的效果. 如果NAC无效,即使有计划的手术,也可能需要进一步的治疗.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 胃肠道瘤学 胃肠道瘤学
背景情况:
- 高风险的局部晚期直肠癌 (LARC) 存在重大治疗挑战.
- 新辅助化疗 (NAC) 是管理LARC的一个关键组成部分.
- 没有放射治疗的NAC在高风险LARC中的作用需要进一步调查.
研究的目的:
- 为了评估高风险的LARC患者的短期/中期外科结局,这些患者在没有放射治疗的情况下接受了NAC (S-1 + 氧沙 + 贝瓦西祖马布) 治疗.
- 评估病理完整反应 (ypT0-2) 和无病生存率.
主要方法:
- 一组32名高风险LARC患者 (定义为cT4b,MRF ≤1mm或cLLN+) 接受了四次NAC治疗.
- 患者在没有新辅助放射治疗的情况下接受了手术.
- 分析了包括病理反应,生存率和局部复发在内的结果.
主要成果:
- 在45.1%的患者中,获得了病理完整反应 (ypT0-2).
- 三年无病生存率 (3yDFS) 为 ypT0-2 的 81.2%,为 ypT ≥3.6 的 46.6%.
- 三年局部复发 (3yLR) 在ypT0-2时为0%,在ypT ≥3.8时为48.8%.
结论:
- NAC在约一半高风险LARC患者中显示出临床显著的效果.
- 如果单独使用NAC是无效的,就应该考虑放射治疗,即使计划进行扩展性手术.
- 这种方法提供了有希望的结果,但强调了需要量身定制的治疗策略.

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.

Cancer Therapies

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...
