Figures & data
Figure 1. This figure describes the features of progression free survival curves of cytotoxic drug, molecular targeted drug and immune checkpoint inhibitor. The patients treated with immune checkpoint inhibitors are divided into three groups according to antitumor effects, non-responder, short-term responder and long-survivor.
Figure 2. This scheme describes how antitumor effector T cells are interacting each other to kill tumor cells and how PD-1 suppresses the T cell functions.
