Intrinsic Genomic Differences Between African American and White Patients With Clear Cell Renal Cell Carcinoma

Abstract

African American patients have less frequent VHL inactivation, are enriched in the ccB molecular subtype, and have decreased up-regulation of HIF-associated gene signatures than white patients. These genomic differences would predict decreased responsiveness to VEGF-targeted therapy and are a biologically plausible contributing factor to the worse survival of African American patients with ccRCC, even in the targeted therapy era.
