概括
获得病理完整反应 (pCR) 的三阴性乳腺癌患者的整体复发次数较少. 然而,PCR幸存者面临的中枢神经系统复发的比例更高,这表明了明显的失败模式.
科学领域:
- 在瘤学瘤学.
- 临床研究 临床研究
背景情况:
- 三阴性乳腺癌 (TNBC) 具有远程转移的高风险.
- 新辅助化疗后的病理完整反应 (pCR) 与更好的结果有关.
- 在TNBC中,pCR可能无法完全预防中枢神经系统 (CNS) 复发.
研究的目的:
- 分析新辅助化疗后TNBC患者的复发模式.
- 在TNBC中调查pCR和中枢神经系统复发之间的关系.
- 在TNBC幸存者中识别明显的失败模式.
主要方法:
- 对774名TNBC患者的回顾性分析.
- 在pCR和没有pCR的患者之间,复发率和复发部位的比较.
- 对中枢神经系统复发比例相对于所有复发的统计分析.
主要成果:
- 在PCR患者中,中枢神经系统复发的数量较少 (5.0%与8.8%相比).
- 中枢神经系统复发在pCR患者中占所有复发的比例明显高 (50.0%对20.2%).
- pCR与一种独特的中枢神经系统占主导地位的失败模式有关.
结论:

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...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates these...
