The purpose of this non-treatment, non-interventional protocol is to collect, preserve, and store excess tumor specimens, which would otherwise be discarded, following routine nephrectomy for subjects with advanced renal cell carcinoma (RCC). The collected tumor specimen will be preserved under current Good Manufacturing Practice conditions and will not be used for any other research or therapeutic purpose without a separate consent from the subject, specific to the intended use on a separate Institutional Review Board or Institutional Ethics Committee approved Argos sponsored study.
