Summary:

      This phase III trial studies rituximab and yttrium Y-90 ibritumomab tiuxetan to see how well
      they work compared to rituximab alone in treating patients with untreated follicular
      lymphoma. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's
      immune system attack the cancer, and may interfere with the ability of tumor cells to grow
      and spread. Radioactive substances linked to monoclonal antibodies can bind to cancer cells
      and give off radiation which may help kill cancer cells. It is not yet known whether
      rituximab works better with or without yttrium Y-90 ibritumomab tiuxetan in treating
      follicular lymphoma.
