The selection of targeted therapies for relapsed or refractory advanced renal cell carcinoma

The treatment of R/R RCC primarily consists of inhibition of VEGF, HIF, and mTOR pathways, and the selection of a specific agent depends on the histologic subtype of the tumor, the prior lines of therapy chosen, and patient co-morbidities. Future tumor-based and circulating biomarker research might one day enable the identification of transcriptional signatures that could predict a response to immune, angiogenesis, or HIF-based therapies.
