This phase I trial studies the side effects and best dose of bortezomib when given together with lenalidomide in treating patients with acute myeloid leukemia or myelodysplastic syndrome that has come back (relapsed) after donor stem cell transplant. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stimulate or suppress the immune system in different ways and stop cancer cells from growing. It may also stop the growth of acute myeloid leukemia or myelodysplastic syndrome by blocking the growth of new blood vessels necessary for tumor growth. Giving bortezomib together with lenalidomide may be a better treatment for acute myeloid leukemia or myelodysplastic syndrome.

PRIMARY OBJECTIVES:
I. Establish the maximum tolerated dose (MTD) of Velcade (bortezomib), up to 1.3 mg/m^2/day that can be administered in combination with lenalidomide 50 mg daily in patients with relapsed acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) after allogeneic stem cell transplant (SCT).
II. Determine the toxicity profile of Velcade when used in combination with lenalidomide in patients with relapsed AML or MDS after allogeneic SCT.
SECONDARY OBJECTIVES:
I. Assess efficacy in terms of complete remission (CR) rates following up to 2 induction cycles of lenalidomide in addition to Velcade.
II. Document the duration of CR in patients who achieve CR.
III. Determine the relapse free survival (RFS) and overall survival (OS) of patients enrolled in this study.
IV. Assess the association between cluster of differentiation (CD)74 expression and clinical outcomes (attainment of CR, disease free survival [DFS] and OS).
OUTLINE: This is a dose-escalation study of bortezomib.
INDUCTION PHASE: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 and bortezomib subcutaneously (SC) on days 2, 5, 9, and 12. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients achieving partial remission (PR), CR, or CR with incomplete hematologic recovery (CRi) may proceed to maintenance therapy.
MAINTENANCE PHASE: Patients receive lenalidomide PO QD on days 1-21 and bortezomib SC on days 2 and 5. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then monthly thereafter.
