Prostate cancer is the most common non-cutaneous malignancy in American men. Docetaxel is a useful chemotherapeutic agent for prostate cancer that has been available for over a decade, but the length of the treatment and systemic side effects hamper compliance. Additionally, docetaxel resistance invariably emerges, leading to disease relapse. Docetaxel resistance is either intrinsic or acquired by adopting various mechanisms that are highly associated with genetic alterations, decreased influx and increased efflux of drugs. Several combination therapies and small P-glycoprotein inhibitors have been proposed to improve the therapeutic potential of docetaxel in prostate cancer. Novel therapeutic strategies that may allow reversal of docetaxel resistance include alterations of enzymes, improving drug uptake and enhancement of apoptosis. In this review, we provide the most current docetaxel reversal approaches utilizing nanotechnology. Nanotechnology mediated docetaxel delivery is superior to existing therapeutic strategies and a more effective method to induce P-glycoprotein inhibition, enhance cellular uptake, maintain sustained drug release, and improve bioavailability.
前列腺癌是美国男性中最常见的非皮肤恶性肿瘤。多西他赛是一种用于前列腺癌的有效化疗药物,已上市十多年,但治疗时间长和全身副作用妨碍了患者的依从性。此外,多西他赛耐药性总会出现,导致疾病复发。多西他赛耐药性要么是内在的,要么是通过采用与基因改变、药物流入减少和流出增加高度相关的各种机制而获得的。已经提出了几种联合疗法和小的P-糖蛋白抑制剂来提高多西他赛在前列腺癌中的治疗潜力。可能使多西他赛耐药性逆转的新型治疗策略包括改变酶、改善药物摄取和增强细胞凋亡。在本综述中,我们提供了利用纳米技术的最新多西他赛逆转方法。纳米技术介导的多西他赛递送优于现有的治疗策略,是诱导P-糖蛋白抑制、增强细胞摄取、维持持续药物释放和提高生物利用度的更有效方法。
