Marrow transplantation for leukemia following fractionated total body irradiation. A comparative trial of methotrexate and cyclosporine.

Journal Article

Fifty-six patients, 30-47 yr of age, with leukemia in relapse received allogeneic marrow transplants from HLA-identical siblings. All patients were treated with cyclophosphamide (120 mg/kg) and 7 daily fractions of 2.25 Gy of total body irradiation (TBI) for seven consecutive days. Nine patients (16%) are currently alive and free of disease 324-845 days from transplantation. The actuarial relapse and survival rates at 2 yr were 56% and 9.5% respectively. These data were not remarkably different from those in previous studies using 10 Gy of TBI administered as a single dose. Thirty patients were randomized to receive methotrexate (MTX) and 26 to receive cyclosporine (CSP) as postgrafting prophylaxis for acute graft-versus-host disease (GVHD). The probability of developing significant acute GVHD by day 100 post-transplant was 71% for patients in the MTX group and 45% for patients in the CSP group (p less than 0.05). The probability of relapse was 37% for patients in the MTX group and 70% for patients in the CSP group (p less than 0.05). Transplant-related deaths were more frequent in the MTX group and leukemic deaths were more frequent in the CSP group although this may have been related to an uneven distribution of high-risk patients. Long-term disease-free survival was comparable. Patients in the MTX group had more severe mucositis, more alveolar pneumonias and possibly more deaths due to complications of acute and chronic GVHD. Patients in the CSP group had a higher incidence of hypertension, neurological complications and renal dysfunction.
