We examined transplantation outcomes after a second HLA-matched sibling transplantation for primary (16%) or secondary (84%) graft failure in 166 patients with severe acquired aplastic anemia (AA). Two-thirds of these patients has a performance score > 90. In most cases (88%), the same donor was used for both transplants, for both transplantations, and 84% of the second transplantations used bone marrow grafts. We identified 2 prognostic factors: intertransplantation interval (surrogate for primary graft failure and early secondary graft failure) and performance status. Shorter intertransplantation interval (>or= 3 months) and poor performance score (> 90) at second transplantation were associated with high mortality. In patients with a performance score of 90% to 100%, the 8-year probability of overall survival (OS) after second transplantation >or= 3 and < 3 months from first transplantation was 56% and 76%, respectively. The corresponding probabilities in patients with lower performance scores were 33% and 61%. The predominant cause of failure after second transplantation was nonengraftment (in 72 of 166 patients), most commonly in patients with primary or early secondary graft failure (51 of 72; 71%). Our data indicate that novel approaches, including conditioning regimens with greater immunosuppression, should be explored for these patients.
