- 在瘤学瘤学.
- 胃肠道手术 胃肠道手术
- 化疗研究 化疗研究
背景情况:
- 新辅助化疗 (NAC) 建议用于局部晚期结肠癌 (LACC),包括临床T4b病例.
- 由于临床试验数据不确定,LACC中NAC的长期存活益处仍在争论中.
- 确定从NAC中获益最多的患者子组对于个性化治疗策略至关重要.
研究的目的:
- 评估新辅助化疗 (NAC) 在局部晚期结肠癌 (LACC) 患者的疗效.
- 根据结肠癌的不同组织学亚型,评估NAC对生存结果的影响.
主要方法:
- 对3709名接受治疗切除 (2014-2018) 的LACC患者进行了回顾性分析.
- 新辅助化疗 (NAC) 和辅助化疗 (AC) 组之间的比较.
- 倾向性得分匹配 (PSM) 用于混调整;卡普兰-梅尔 (K-M) 曲线和日志等级测试用于生存分析.
主要成果:
- 与AC相比,接受NAC的非性腺癌 (NMAC) 患者的5年整体存活率 (OS) (76.3%对69.2%) 和无病存活率 (DFS) (67.2%对60.1%) 显著改善.

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
134
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...

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...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
143
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
