Abstract

Throughout a 4-year period, we reinfused autologous peripheral stem cells rather than purged autologous bone marrow following high-dose therapy to 57 patients with relapsed lymphoma and bone marrow metastases. Approximately 7 x 108 circulating mononuclear cells/kg patient weight were collected for each patient with 6-19 4-h apheresis procedures while hemopoiesis was unperturbed. Following collection, the cells were cryopreserved. Administration of high-dose therapy, which included either combination chemotherapy or combination chemotherapy plus total body irradiation, was followed by i.v. administration of the thawed autologous stem cells. The rate of hemopoietic recovery varied with the specific high-dose therapy administered. Sixty-two percent of 50 evaluable patients had a clinical complete response. The actuarial event-free survival for these patients 4 years after transplantation was 30%, and the projected survival at 4 years was 51%. Patients with relapsed lymphoma and bone marrow metastases who receive high dose therapy followed by peripheral stem cell transplantation can experience long-term event-free survival. Whether similar patients would fare as well with the same high-dose therapy followed by a purged autologous bone martow transplantation would require a randomized prospective study.
