Stem cell Infusion without TBI: no evidence of active graft vs host disease and at least days must have elapsed after transplant or stem cell infusion No evidence of active graft versus (vs.) host disease and >= months must have elapsed since transplant Stem cell transplant or rescue: no evidence of active graft versus (vs.) host disease and ? months must have elapsed since transplant prior to registration Stem cell infusion without TBI: no evidence of active graft versus host disease and at least days must have elapsed after transplant, and days for autologous stem cell infusion after I^-MIBG therapy No evidence of active graft versus host disease and >= months must have elapsed since transplant or rescue Stem Cell Transplant or Rescue: No evidence of active graft vs. host disease and ? months must have elapsed since transplant. Hematopoietic cell transplant or other cellular based therapy within days before the planned start of study treatment or patients with active graft-vs-host disease with the exception of Grade skin involvement No evidence of active graft vs. host disease and at least months must have elapsed since transplant The patient must have no evidence of active graft vs. host disease, and greater than or equal to weeks must have elapsed since transplant or stem cell infusion and enrollment on this study for any other pathology No evidence of active graft vs. host disease and at least days must have elapsed after transplant or stem cell infusion. Stem Cell Transplant or Rescue: No evidence of active graft vs. host disease and ? months must have elapsed since transplant. Stem cell transplant or rescue: >= months must have elapsed since the time of transplant; patients with active graft-vs-host disease (GVHD) are eligible if the disease is well controlled on GVHD medications and they are clinically stable Stem cell infusion without TBI: no evidence of active graft vs. host disease and at least days must have elapsed after transplant or stem cell infusion Bone marrow/stem cell transplant or infusion without TBI:\r\n* Part A or Part C: No evidence of active graft vs host disease and >= months must have elapsed since stem cell transplant or infusion\r\n* Part A, Part A, or Part B: No evidence of active graft vs host disease and >= weeks must have elapsed since stem cell transplant or infusion Prior allogeneic stem cell transplant within one year or active graft vs. host disease.
