N2 - Transplantation protocols for patients with Fanconi anemia are being modified continuously. However, it is unclear how outcomes have changed over time. We determined historical adverse event rates from long-term follow-up of 117 Fanconi anemia patients in the Hôpital Saint Louis transplant cohort, who received low-dose cyclophosphamide- and irradiation-based conditioning, in combination with other modalities, between 1976 and October 2002. In high-risk patients with mismatched donors, the peritransplantation mortality rate during 0 to 6 months declined significantly over time (P = .003), from 28%/month (95% confidence interval [CI], 9%-87%/month) during 1985 to 1989 to 3.3%/ month (95% CI, 0.8%-13.3%/month) during 2000 to October 2002. The corresponding proportion of patients who developed severe acute graft-versus-host disease also declined significantly over time (P = .003). In low-risk patients with matched sibling donors, the peritransplantation mortality rate was consistently low, 1.4%/month (95% CI, 0.3%-5.3%/month), during 1990 to October 2002. Sample sizes to detect 2-fold reductions from rates and risks observed since the mid-1990s are larger than recently reported case series. To demonstrate further advances in survival, transplant centers may need to coordinate their protocols and engage in multicenter collaborative studies.
