This phase I trial studies the side effects and best dose of lenalidomide after donor stem cell transplant and bortezomib in treating patients with multiple myeloma that is likely to recur (come back) or spread. Giving low doses of chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It may also help the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving bortezomib at the time of transplant may stop this from happening. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Giving lenalidomide after donor stem cell transplant may be a better treatment for multiple myeloma.

PRIMARY OBJECTIVES:
I. Identify the maximal tolerated dose (MTD) and safety of lenalidomide up to 10 mg following non-myeloablative allogeneic stem cell transplant for multiple myeloma.
SECONDARY OBJECTIVES:
I. Assess safety and tolerability of weekly bortezomib following allogeneic hematopoietic stem cell transplant (alloHSCT).
II. Obtain estimates of transplant-related mortality (TRM).
III. Obtain estimates of acute and chronic graft-versus-host disease (GVHD).
IV. Obtain estimates of 1 year relapse and survival.
OUTLINE: This is a dose-escalation study of lenalidomide.
PREPARATIVE REGIMEN: Patients receive fludarabine phosphate on days -5 to -3 and undergo total body irradiation (TBI) on days -1 to 0.
TRANSPLANT: Patients undergo allogeneic hematopoietic stem cell transplant (SCT) on day.
GVHD PROPHYLAXIS: Patients receive standard GVHD prophylaxis comprising cyclosporine orally (PO) twice daily (BID) beginning on day -1 with taper beginning on day 100, mycophenolate mofetil PO BID on days 1-56, and bortezomib subcutaneously (SC) or intravenously (IV) weekly on days 1-91.
MAINTENANCE THERAPY: Beginning after day 100 and before day 150, patients receive lenalidomide PO daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up monthly for 1 year post-transplant.
