Summary:

      This phase II trial studies how well pazopanib hydrochloride works in treating patients with
      kidney cancer that has spread to other places in the body (metastatic). Pazopanib
      hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for
      cell growth. Pazopanib hydrochloride may also stop the growth of kidney cancer by blocking
      blood flow to the tumor.
