RATIONALE: Giving low doses of chemotherapy, such as cyclophosphamide and fludarabine, before a donor peripheral blood stem cell transplant helps stop the growth of tumor cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system and help destroy any remaining tumor cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving antithymocyte globulin before the transplant and cyclosporine after the transplant may stop this from happening.
PURPOSE: This phase II trial is studying how well cyclophosphamide, fludarabine, antithymocyte globulin, and peripheral stem cell transplant followed by cyclosporin and donor white blood cell transfusions work in treating patients with refractory metastatic solid tumors.
- Identify an anti-tumor effect of allogeneic peripheral blood stem cell transplantation by induction of a graft-versus-tumor effect in patients with a diversity of metastatic solid tumors refractory to standard therapy.
- Determine engraftment in these patients.
- Determine the effects of donor lymphocyte infusion and cyclosporine withdrawal on tumor regression in these patients.
OUTLINE: Patients are stratified according to risk of graft rejection, which determines the preparative regimen received. High-risk patients include heavily transfused patients or patients who have received donor-directed blood products and single HLA-locus mismatched patients.
Preparative regimen: Patients receive cyclophosphamide IV over 1 hour on days -7 and -6 and fludarabine IV over 30 minutes on days -5 to -1. Patients at high risk also receive antithymocyte globulin IV on days -5 to -2.
Patients undergo allogeneic peripheral blood stem cell transplantation on day 0. Patients receive cyclosporine either by continuous infusion IV or orally twice a day on days -4 to 100 as graft-versus-host disease (GVHD) prophylaxis.
Patients with less than 100% donor T-cell chimerism or with evidence of tumor progression receive donor lymphocytes after day 100, every 4 weeks, until 100% donor T-cell chimerism, disease regression, and/or GVHD occurs.
Patients are followed at 4, 6, 8, 10, and 12 months, every 3 months for 2 years, and then every 6 months for 2 years.
PROJECTED ACCRUAL: Approximately 150 patients (10 for each cancer) will be accrued for this study.

A cyclic undecapeptide from an extract of soil fungi. It is a powerful immunosupressant with a specific action on T-lymphocytes. It is used for the prophylaxis of graft rejection in organ and tissue transplantation. (From Martindale, The Extra Pharmacopoeia, 30th ed).
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Immunizing agent containing IMMUNOGLOBULIN G anti-Rho(D) used for preventing Rh immunization in Rh-negative individuals exposed to Rh-positive red blood cells.
A glycoprotein migrating as alpha 1-globulin, molecular weight 70,000 to 120,000. The protein, which is present in increased amounts in the plasma during pregnancy, binds mainly progesterone, with other steroids including testosterone competing weakly.
N(2)-((1-(N(2)-L-Threonyl)-L-lysyl)-L-prolyl)-L-arginine. A tetrapeptide produced in the spleen by enzymatic cleavage of a leukophilic gamma-globulin. It stimulates the phagocytic activity of blood polymorphonuclear leukocytes and neutrophils in particular. The peptide is located in the Fd fragment of the gamma-globulin molecule.
Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
