Anti-IMP3 Autoantibody and MicroRNA Signature Blood Tests in Finding Metastasis in Patients With Localized or Metastatic Kidney Cancer

PRIMARY OBJECTIVE: I. To develop a blood test by monitoring the titer of IMP3 autoantibody and/or microRNA (miRNA)/small non-coding RNA (snRNA) expression in patients' serum for the early detection of RCC and its recurrence/metastasis. OUTLINE: Serum samples are collected prior to treatment and analyzed for anti-IMP3 autoantibody titer via enzyme-linked immunosorbent assay (ELISA) and total RNA via sequencing, microarray, and/or quantitative polymerase chain reaction (q-PCR). Previously collected tissue samples are analyzed for IMP3 via immunohistochemistry (IHC).
