An Evolving Role for AXL in Metastatic Renal Cell Carcinoma

Abstract

High tumoral expression of AXL was associated with inferior response to anti-PD-1 therapy and increased tumoral programmed death ligand 1 (PD-L1) expression in patients with metastatic renal cell carcinoma, with particularly poor outcomes in those with high AXL and PD-L1. AXL expression has potential as a biomarker and therapeutic target.
