Allo Non-Myeloablative SCT Utilizing Mis-Matched Family Member Stem Cells Purged Using Campath

Inclusion Criteria

• Patients must have their pathology reviewed and the diagnosis confirmed.
• Performance status (PS) must be Cancer and Leukemia Group B (CALGB) PS 0, 1, or 2
• Patients must have a 3-5/6 Human leukocyte antigen (HLA)-matched related donor who is evaluated and deemed able to provide peripheral blood progenitor cells (PBPCs) and/or marrow by the transplant team.
• HIV antibody negative.
• Patients must test negative for serum beta-human chorionic gonadotropin (hCG) and must agree to use some form of adequate birth control during the periods they receive chemotherapy and any post-chemotherapy medications related to the transplant.
• Patients must be 17 years of age or greater.
• Patients must also have a resting Multi Gated Acquisition Scan (MUGA) and/or echocardiography (ECHO) and pulmonary function tests (PFTs) with testing of diffusing capacity of the lung for carbon monoxide (DLCO) performed before transplant and found to be acceptable according to the treating institution's guidelines. The required minimum standards include MUGA and/or ECHO showing an ejection fraction (EF) of 40% and PFTs showing DLCO of 40%. Those with an EF 40-50%, undergo cardiac evaluation and consultation. Also, those with DLCO 40-50%, undergo pulmonary evaluation and consultation.
• Specific populations for each disease category:
• Hematologic malignancies Those with high risk or relapsed hematologic malignancy (including myeloid and lymphoid leukemias and lymphomas, myeloma or myelomatous like diseases, myeloproliferative disease, myelodysplasia). Those with good risk disease (first remission acute myeloid leukemia (AML) with myelomonocytic together with bone marrow eosinophilia (M4eos) - inversions in chromosome 16, promyelocytic (M3) AML with translocations in chromosomes (15;17); or translocations in chromosomes (8;21) in first remission are not eligible).
• Bone marrow failure:
• Those specifically with idiopathic or secondary moderate, severe or very severe aplastic anemia (idiopathic or secondary) according to the accepted 'Camitta criteria' would be candidates.
• Those with diseases known to lead to severe marrow failure are eligible as well. These include those with myelofibrosis or Paroxysmal nocturnal hemoglobinuria (PNH).
• Solid Tumors:
• Patients must have had a biopsy confirming disease recurrence (metastases) at some point in their history, unless the patient presented with metastatic disease, in which case the initial primary site biopsy is adequate.
• Patients with renal cell cancer, or melanoma will be eligible for this approach at this time. Patients will have had documented metastatic disease at some time in the past. Patients who are in remission or with residual disease after prior therapy for their metastatic disease are eligible, as there is no accepted cure for these patients with metastatic disease.
• Breast Cancer- Patients will have had documented metastatic disease at some time in the past. Patients who are in remission or with residual disease after prior therapy for their metastatic disease are eligible. Patient must have failed at least one chemotherapy regimen for their metastatic disease and 1 hormonal agent if they are receptor positive.

Exclusion Criteria

• Pregnant or lactating women,
• Patients with other major medical or psychiatric illnesses which the treating physician feels could seriously compromise tolerance to this protocol, and
• Leukemia patients in first remission with good risk cytogenetics for leukemia [t(15;17); t(8,22)]
