摘要

Introduction: Immune-based therapies (e.g., IFN) have been used for some time in advanced clear cell renal cell carcinoma (RCC) with overall modest success. Recent advances have demonstrated that tumor cells evade immune-mediated destruction by inducing inhibitory signals that result in effector T-cell exhaustion. One mechanism involves interaction between the T-cell programmed death-1 (PD-1) receptor and its ligand, PD ligand-1, expressed on tumor and inflammatory cells. Nivolumab, an anti-PD-1 antibody, blocks this pathway, thereby reversing T-cell suppression and activating antitumor responses.
