Removing the so-called 'brakes' on T cell immune responses by blocking the PD-1/PDL1 check point should boost anti-tumor immunity and provide durable tumor regression for cancer patients.However, 30%–60% of patients show no response to PD-1/PD-L1 blockade. Thus, it is urgent to explore the underlying resistance mechanisms to improve sensitivity to anti-PD-1/PD-L1 therapy. We propose that the mechanisms promoting resistance mainly include T cell exclusion or exhaustion at the tumor site,immunosuppressive factors in the tumor microenvironment(TME), and a range of tumor-intrinsic factors. This review highlights the power of studying the cellular and molecular mechanisms of resistance to improve the rational design of combination therapeutic strategies that can be translated to the clinic. Here, we briefly discuss the development of PD-1/PD-L1 blockade agents and focus on the current issues and future prospects for potential combinatorial therapeutic strategies that include anti-PD-1/PD-L1 therapy, based upon the available preclinical and clinical data. 关键词：治疗学肿瘤免疫应用抵抗机制免疫疗法微型环境房间封锁
