概括
在接受胸部放射治疗的高级非小细胞肺癌患者中,无溶剂纳米颗粒与蛋白结合的帕克利塔塞尔 (nab-paclitaxel) 显示出比基于溶剂的帕克利塔塞尔 (sb-paclitaxel) 更高的毒性和更低的疗效.
科学领域:
- 医学瘤学 医学瘤学
- 临床试验 临床试验
- 辐射瘤学 辐射瘤学
背景情况:
- 局部发达的非小细胞肺癌 (NSCLC) 需要有效的治疗策略.
- 胸部放射治疗 (RT) 与化疗相结合是一种标准的方法.
- 不同的帕克利塔塞尔配方可能会影响治疗结果.
研究的目的:
- 为了比较胸部RT加卡博普拉丁的疗效和毒性与以溶剂为基础的帕克利塔塞尔 (sb-paclitaxel) 或纳米颗粒蛋白结合的帕克利塔塞尔 (nab-paclitaxel).
主要方法:
- 一个多中心的1/2期随机试验在患有不可手术的IIIA/B期NSCLC的患者中进行.
- 第1阶段确定了nab-paclitaxel的剂量.
- 2期随机分配患者每周服用sb-paclitaxel或nab-paclitaxel与并发RT,然后进行整合治疗.
主要成果:
- 与sb-paclitaxel (30%) 相比,nab-paclitaxel与3级或更高不良事件的更高率 (56%) 相关.
- 较少的患者完成了nab-paclitaxel的整合治疗 (26%) 与sb-paclitaxel (58%) 相比.
- 纳布-帕克利塔塞尔的2年总生存率 (56%vs. 67%) 和无进展生存率 (27%vs. 44%) 在数值上较低.
结论:
- 与sb-paclitaxel相比,nab-paclitaxel在这种NSCLC治疗环境中表现出增加的毒性和数值较低的疗效.
- 在局部晚期的NSCLC中,Sb-paclitaxel可能是与胸部RT和carboplatin同时进行和巩固治疗的首选选择.

Treatment Resistant Cancers
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...
