The Intratumoral Balance between Metabolic and Immunologic Gene Expression Is Associated with Anti–PD-1 Response in Patients with Renal Cell Carcinoma

Pretreatment tumor PD-L1 expression has been shown to correlate with response to anti-PD-1/PD-L1 therapies. Yet, most patients with PD-L1(+) tumors do not respond to treatment. The current study was undertaken to investigate mechanisms underlying the failure of PD-1-targeted therapies in patients with advanced renal cell carcinoma (RCC) whose tumors express PD-L1. Formalin-fixed, paraffin-embedded pretreatment tumor biopsies expressing PD-L1...
