摘要: 胰腺癌的恶性程度极高,发现时通常已至晚期,中位生存时间极短,严重威胁人类生命健康。并且与其他癌种相比,近些年取得的治疗进展也十分有限。免疫检查点抑制剂(Immune checkpoint inhibitors,ICIs)作为近几年的新兴药物已在多个肿瘤中获得了令人振奋的治疗效果,但是在胰腺癌中却遭遇了滑铁卢。胰腺癌对ICIs治疗不敏感的原因可能包括以下几个方面:一是胰腺癌抗原性弱,不足以激活免疫系统;二是免疫微环境中致密的结缔组织阻碍药物浸润;三是大量免疫抑制细胞构成的免疫抑制微环境,抑制T淋巴细胞活化等。但最新的研究表明以ICIs为基础的联合治疗方案能够通过增加肿瘤抗原的暴露,打破间质屏障及改善免疫抑制微环境等方法增加胰腺癌对ICIs治疗的敏感性,从而发挥积极的抗肿瘤作用。本文将以ICIs为基础的联合治疗方案在胰腺癌治疗领域所取得的进展进行综述。

Abstract: Pancreatic cancer is extremely malignant.It is usually in the advanced stage when discovered,and the median survival time is extremely short,which seriously threatens human life and health.Compared with other cancers,the treatment progress made in recent years is also very limited.Immune checkpoint inhibitors(ICIs),as emerging drugs in recent years,have achieved exciting therapeutic effects in multiple tumors,but they have encountered Waterloo in pancreatic cancer.The reasons why pancreatic cancer is not sensitive to ICIs treatment may include the following aspects:first,pancreatic cancer is weak antigenic and insufficient to activate the immune system;second,the dense connective tissue in the immune microenvironment hinders drug infiltration;third,the immunosuppressive microenvironment formed by a large number of immunosuppressive cells inhibits the activation of T lymphocytes.However,the latest research shows that ICIs-based combination therapy can increase the sensitivity of pancreatic cancer to ICIs treatment by increasing the exposure of tumor antigens,breaking the interstitial barrier,and improving the immunosuppressive microenvironment,thereby exerting a positive anti-tumor effect.This article reviews the progress made in the field of pancreatic cancer treatment based on ICIs-based combination therapy.
