Abstract

Pancreatic cancer has historically proven resistant to anticancer agents. On the one hand, drugs might be more efficient if higher levels could be achieved at the tumor site rather than the normal tissues. On the other hand, the thick stroma and the relative absence of abundant vessels may account at least partially for the failure of successive clinical trials to demonstrate effective treatments in this type of malignancy. In this context, the development and testing in clinical trials of treatment strategies that aim to optimize drug delivery is an important target in improving the prognosis of patients with pancreatic cancer.

摘要

胰腺癌在历史上已被证明对抗癌药物具有耐药性。一方面,如果在肿瘤部位而不是正常组织中能达到更高的药物浓度,药物可能会更有效。另一方面,厚实的基质和相对缺乏丰富的血管可能至少部分解释了为什么在这种类型的恶性肿瘤中,连续的临床试验未能证明有效的治疗方法。在这种情况下,旨在优化药物递送的治疗策略的开发和临床试验是改善胰腺癌患者预后的一个重要目标。
