Summary:

      RATIONALE: Monoclonal antibodies such as rituximab and yttrium Y 90 ibritumomab tiuxetan can
      locate cancer cells and either kill them or deliver radioactive cancer-killing substances to
      them without harming normal cells. Drugs used in chemotherapy use different ways to stop
      cancer cells from dividing so they stop growing or die. Combining rituximab and combination
      chemotherapy with yttrium Y 90 ibritumomab tiuxetan may kill more cancer cells.

      PURPOSE: Phase II trial to study the effectiveness of combining rituximab and combination
      chemotherapy with yttrium Y 90 ibritumomab tiuxetan in treating older patients who have
      B-cell lymphoma that has not been previously treated.
