Patients who have received prior lenalidomide therapy will be eligible if >= partial response (PR) was observed on a prior lenalidomide containing regimen and patients did not progress while receiving lenalidomide; isolated bone lytic lesions in the absence of measurable para-proteins will not be considered measurable disease

Serum bilirubin =< 1.5 times upper limit of normal (ULN)
Serum glutamic oxaloacetic transaminase (SGOT)/serum glutamic pyruvic transaminase (SGPT) =< 3x ULN
Calculated creatinine clearance >= 60ml/min by Cockcroft-Gault formula; creatinine clearance >= 60 ml/min or serum creatinine =< 2.0 mg/dL
Absolute neutrophil count (ANC) >= 1500/uL
Platelet count >= 100,000/ uL
Hemoglobin (Hgb) >= 10 g/dL following recovery from last therapy
Cardiac and pulmonary function adequate for transplant
Ability to sign informed consent
All study participants must be registered into the mandatory RevAssist program, and be willing and able to comply with the requirements of RevAssist
Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10-14 days prior to and again within 24 hours of prescribing lenalidomide (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide; FCBP must also agree to ongoing pregnancy testing
Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy

Exclusion criteria:
