与全身化疗相比,高温胸内化疗 (HITHOC) 和高温腹内化疗 (HIPEC) 分别增加胸腔和腹腔中西斯的暴露. 这些局部治疗方法与传统方法具有相似的安全性.
科学领域:
- 药理动力学和瘤学
- 药物输送系统 药物输送系统
- 癌症治疗方法 癌症治疗方法
背景情况:
- 西斯是一种基石化疗剂,用于治疗各种癌症.
- 系统化疗 (SC) 导致药物广泛分布和潜在的毒性.
- 超热性胸内化疗 (HITHOC) 和超热性腹内化疗 (HIPEC) 是区域化疗输送方法.
研究的目的:
- 为了比较通过 SC 与 HITHOC 或 HIPEC 进行的西斯普拉丁的药理动力学.
- 评估和比较与这些不同的施用方法相关的不良影响.
- 提供药理动力学证据支持局部高热化疗的疗效.
主要方法:
- 60名患者被分为三个组:SC,HITHOC和HIPEC.
- 在HITHOC/HIPEC期间,通过静脉注射 (SC) 或注入输液中给药了标准化剂量 (40mg) 的西斯.
- 使用HPLC量化了血和透的度,分析了AUC0-24h,Cmax和Tmax等参数.
主要成果:
- 与HIPEC相比,在HITHOC中 perfusate cisplatin的AUC0-24h和Cmax显著更高.
- 血思的AUC0-24h和Cmax在HITHOC与SC相比较低,与HIPEC没有显著差异.
- 与SC相比,HITHOC (胸腔) 和HIPEC (腹腔) 腔的绝对生物可用性显著更高,不同组的不良事件没有显著差异.
结论:
- 在胸腔和腹腔中,HITHOC和HIPEC显著增强了对青的局部暴露.
- 这些局部化的高热化疗方法显示出相对于全身管理相比,有利的药物动力学特征.
- 通过HITHOC或HIPEC进行局部应用提供了一种有前途的策略,用于改善恶性多发性溢出或炎的局部药物暴露.

Cancer Therapies
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...
