Popis: BACKGROUND Persons with multiple sclerosis are increasingly treated with intermediate- or high-dose chemotherapy and a hematopoietic cell autotransplant. This is often done in an inpatient setting using frozen blood cell grafts. OBJECTIVE Determine if chemotherapy and a hematopoietic cell autotransplant can be safely done in an outpatient setting using refrigerated, non-frozen grafts. METHODS We developed an autotransplant protocol actionable in an outpatient setting using a refrigerated, non-frozen blood graft collected after giving cyclophosphamide, 50 mg/kg/d × 2 days and filgrastim, 10 μg/kg/d. A second identical course was given 9 days later followed by infusion of blood cells stored at 4°C for 1-4 days. The co-primary outcomes were rates of granulocyte and platelet recovery and therapy-related mortality. RESULTS We treated 426 consecutive subjects. Median age was 47 years (range, 21-68 years). A total of 145 (34%) were male. Median graft refrigeration time was 1 day (range, 1-4 days). Median interval to granulocytes >0.5 × 10E + 9/L was 8 days (range, 2-12) and to platelets >20 × 10E + 9/L, 8 days (range, 1-12). Only 15 subjects (4%) were hospitalized, predominately for iatrogenic pneumothorax (N = 5) and neutropenic fever (N = 4). There was only 1 early death from infection. CONCLUSION Intermediate-dose chemotherapy and a hematopoietic cell autotransplant can be safely done in an outpatient setting using, refrigerated, non-frozen grafts.
