Programmed death1 (PD-1) is mainly expressed on the surface of activated T cell. The combination between PD-1 and its legends PD-L1/PD-L2 activate downstream signaling pathways and negatively regulate T cell activation. Ab?normal increase expression of PD-L1 on tumor cell surface mediates the tumor immune escape. Inhibition of PD-1 signaling pathway contributes to antitumor effect of T cells. The development of this pathway inhibitors has become a hot spot for tu?mor immunotherapy. This article expounds the progress about antitumor effects mediated by PD-1 pathway inhibition from experiments in vivo or in vitro and clinical development of PD-1 pathway inhibitors, providing a new target for cancer immu?notherapy and theoretical and clinical basis for the clinical application of immunotherapy with traditional therapy methods.

The resection can be performed in about 20 percent of patients with primary hepatocellular carcinoma(PHC) in clinic. However, with the development of interventional treatment such as transcatheter arterial chemoembolization(TACE), better therapeutic effect has been achieved by two-stage resection such as TACE in patients with unresectable PHC. At present, surgical resection is still regarded as the first choice of PHC, and the principle of comprehensive therapeutic solutions around surgical operation has been established. The pretreatment of TACE is an important measure to improve the therapeutic effect in PHC.This paper discussed the mechanism, effect and value of TACE in pretreatment of unresectable PHC. The selection of operative opportunity, sign, and ways after TACE and the factors affecting prognosis of two-stage resection were also reviewed.
