Abstract

Pancreatic adenocarcinoma (PAC) remains one of the leading causes of cancer-related death. Despite multiple advances in targeted and immune therapies, the 5-year survival in advanced PAC remains poor. In this review, we discuss some of the unique aspects of the tumor microenvironment (TME) in PAC that may contribute to its resistance to immune therapies, as well as opportunities to potentially overcome some of these inherent barriers. Furthermore, we discuss strategies to enable immune therapies in PAC such as cytotoxic chemotherapy and radiation therapy, cancer vaccines, cytokine based therapy, oncolytic viruses, and adoptive T-cell therapy. Finally, we address a variety of targeted therapies as a strategy to further amplify immune responses in PAC.

摘要

胰腺腺癌(PAC)仍然是癌症相关死亡的主要原因之一。尽管在靶向治疗和免疫治疗方面取得了多项进展,但晚期PAC的5年生存率仍然很低。在本综述中,我们讨论了PAC肿瘤微环境(TME)的一些独特方面,这些方面可能导致其对免疫治疗产生抗性,以及潜在克服其中一些固有障碍的机会。此外,我们还讨论了在PAC中实施免疫治疗的策略,如细胞毒性化疗和放射治疗、癌症疫苗、基于细胞因子的治疗、溶瘤病毒和过继性T细胞治疗。最后,我们探讨了各种靶向治疗方法,作为进一步增强PAC免疫反应的策略。
