Sixty‐two patients with a variety of malignant diseases including 44 with breast cancer, seven with sarcomas, five with germ cell tumours, four with Hodgkin's disease and two with multiple myeloma received short duration, high dose chemotherapy, with non‐cryopreserved peripheral blood progenitor cell rescue as treatment for malignancy. Limited, (one or two) peripheral blood precursor cell collections were performed following either cyclophosphamide, cyclophosphamide + GCSF or GCSF priming. Total nucleated cell and CD34 + cell yields were significantly higher with either of the two GCSF priming regimens as compared to cyclophosphamide only priming. Cell viability at the time or reinfusion was also enhanced by GCSF priming. Chemotherapy regimens included either high dose cyclophosphamide, mitoxantrone and VP16 (HD‐CNV); high dose melphelan plus VP16; high dose BCNU, cyclophosphamide and VP16 (BCV); or high carboplatin, cyclophosphamide and VP16 (PCV) all given over 8–12 h. Non‐cryopreserved blood progenitor cells, stored at 4 °C, were reinfused 24 h after completion of chemotherapy. Sixty‐one of 62 patients showed hematologic recovery. Median time to hematologic recovery was significantly shorter for patients receiving GCSF primed cell collections. There was also significantly less hospitalization and antibiotic usage for patients receiving GCSF primed precursor cell collections. The addition of post chemotherapy GCSF did not, however, appear to enhance the rate of hematologic recovery. This study shows that simplified schedules for high dose chemotherapy administration together with simple precursor cell collection procedures provide safe and effective methods for administering myeloablative chemotherapy treatment.
