Spots Global Cancer Trial Database for Circulating Tumors Cells and Circulating Endothelial Cells in Renal Cell Carcinoma

Study Description

Brief Summary: The purpose of this study is to see if researchers can detect circulating tumor cells (CTC) and circulating endothelial cells (CEC) in the blood.

Detailed Description: Circulating tumors cells (CTCs) and circulating endothelial cells (CECs) are found in the peripheral blood of most common malignancies and are promising surrogate biomarkers. The CellSearchTM CTC assay is currently approved by the Food and Drug Administration as an adjunct for monitoring disease status in breast, prostate and colon carcinomas; and evidence in breast cancer suggests that CTCs are an independent predictor of overall survival and progression-free survival. Evolving data demonstrates a potential role of CTCs as a surrogate assessment for treatment response. The benefit of this approach in renal cell cancer(RCC) is unknown and further investigation is needed to determine the feasibility of using the CellSearchTM CTC Assay in this malignancy. Circulating endothelial cells (CECs) are increased in the peripheral blood of cancer patients and appear to be a marker of tumor related angiogenesis. Studies suggest that CECs increase in the setting of progressive disease and decrease in response to treatment with an antiangiogenic agent. Although current data evaluating CECs in RCC is limited, there is significant interest in CEC evaluation as a marker of treatment response given the majority of current FDA approved RCC therapies target tumor angiogenesis. The overall objective of this protocol is to obtain preliminary data and experience using our Cell Search Assay system which can be used for future grant applications. Our hypothesis is that CTCs and/or CECs will be valuable and versatile biomarkers for therapeutic response, determination of relapse and survival in patients with renal cell cancer.
