Autologous peripheral blood stem cells (PBSC) collected after an intensive course of chemotherapy were employed for hematological reconstitution in 3 patients (age 24-44 years), 2 with Hodgkin's and 1 with high-grade non-Hodgkin's lymphoma, in 2nd complete or partial remission. PBSC collections were performed with a Fenwal CS-3000 cell separator (programs "3" and "1-modified"). After collection and partial RBC removal, cells were cryopreserved and stocked in liquid nitrogen. In all patients the CVB combination was employed as myeloablative transplant regimen. Patients received respectively 28.0, 33.1 and 12.3 x 10(4)/Kg peripheral blood CFU.GM. Hematologic recovery was prompt and complete in 2 patients, while a patient with Hodgkin's lymphoma who had previously been treated with combined modality, is still moderately thrombocytopenic and granulocytopenic 148 days post graft. Patients are currently alive and disease-free 148-301 days post graft.
