Monoclonal Antibody Therapy Plus Cyclosporine and Peripheral Stem Cell Transplantation in Treating Patients With Metastatic Breast Cancer

RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and deliver tumor-killing substances to them without harming normal cells. Peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. Sometimes the transplanted cells can make an immune response against the body's normal tissues. Cyclosporine may prevent this from happening. PURPOSE: Phase I trial to study the effectiveness of radiolabeled monoclonal antibody plus cyclosporine and peripheral stem cell transplantation in treating patients who have metastatic breast cancer that has not responded to previous therapy.
