多靶点酪氨酸激酶抑制剂是临床常用的抗肿瘤药物,其通过抑制细胞信号转导,从而促进肿瘤细胞凋亡,具有选择性高,副作用少的特点。目前在非小细胞肺癌、转移性肾癌、甲状腺癌及血液肿瘤等恶性肿瘤的治疗中应用广泛。但该类药物在临床疗效和药动学特征等方面受多种因素的影响,存在较大的个体差异。近年来,群体药动学研究发展迅速,广泛应用于多种药物的研究。笔者综述了阿昔替尼、伊马替尼、厄洛替尼和舒尼替尼在肿瘤患者及健康人群中的药动学特征及影响因素,进而对其群体药动学研究进展进行总结,分析了其在不同瘤种中的药动学特点及其相关协变量。结果表明,人口统计学因素、基因多态性、血生化指标、合并用药和肝肾功能是影响其在体内代谢的重要因素。试验设计和模型构建等因素可能是导致研究结果产生差异的重要原因。本文为临床制定合理、安全的个体化给药方案制定提供理论参考。

人类表皮生长因子受体2(human epidermal growth factor receptor type 2,HER2)的过度表达是乳腺癌患者预后不良的重要因素之一。近年来,针对HER2的靶向药物显著改善HER2阳性乳腺癌患者的预后、延长生存期,但原发性耐药或在治疗过程中产生的获得性耐药最终仍会导致疾病进展甚至转移。目前抗HER2肿瘤药物的耐药策略研究尚不完善;但随之增多的耐药机制方面的探讨,有助于对抗耐药疗法进行甄别和筛选,同时也促进了更多新药的开发。因此,笔者综述了抗HER2阳性乳腺癌靶向治疗代表药物耐药策略的最新进展,以期为临床制定应对耐药的有效策略或个性化治疗方案提供参考。
