Summary:

      This randomized phase II/III trial studies how well lenalidomide works and compares it to
      observation in treating patients with asymptomatic high-risk asymptomatic (smoldering)
      multiple myeloma. Biological therapies such as lenalidomide, may stimulate the immune system
      in different ways and stop cancer cells from growing. Sometimes the cancer may not need
      treatment until it progresses. In this case, observation may be sufficient. It is not yet
      known whether lenalidomide is effective in treating patients with high-risk smoldering
      multiple myeloma than observation alone.
