Current Status of Predictive Biomarker Development in Metastatic Renal Cell Carcinoma.

PURPOSE OF REVIEW: In this review, we analyze the current state of research in development of new biomarkers that may be useful in managing metastatic renal cell carcinoma (mRCC) setting.

RECENT FINDINGS: Combining tumor-based biomarkers (gene expression profile) and blood-based biomarkers (ctDNA, cytokines) would be helpful in acquiring information regarding RCC and might be significant in the decision-making process. Renal cell carcinoma (RCC) is the sixth most frequently diagnosed neoplasm in men and tithe in women, making it responsible for 5% and 3% of all diagnosed cancers respectively. Metastatic stage represents a non-negligible percentage at diagnosis and is characterized by poor prognosis. Despite clinical features and prognostic score could guide clinicians in therapeutic approach of this disease, biomarkers predictive of response to treatment remain an unmet need.
