Researchers from the John Hopkins University School of Medicine in America have identified potential biomarkers that may predict whether patients with kidney cancer are likely to respond to treatment with immunotherapy drugs that target the PD-1/PD-L1 pathway, such as nivolumab.

However, the researchers noted that not all PD-L1-positive RCCs respond to these immunotherapies.
