With checkpoint inhibitors emerging as potential treatment approaches for advanced renal cell carcinoma, combining or sequencing them with vascular endothelial growth factor receptor (VEGFR)-tyrosine kinase inhibitors (TKIs) may reduce or delay disease progression, according to a recent review. Preliminary evidence suggests that VEGFR-TKIs can reverse immunosuppressive effects in the tumor microenvironment, potentially enhancing the effects of subsequent immunotherapy with checkpoint inhibitors. The authors discuss the potential role of first-line VEGFR-TKIs in priming the tumor microenvironment for immunotherapy.
