Summary:

      This randomized phase II trial studies how well everolimus works in treating patients with
      pancreatic neuroendocrine tumors metastatic to the liver previously treated with surgery.
      Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell
      growth. Giving everolimus after surgery may kill any tumors cells that remain.
