Objectives: The aim of this retrospective study was to assess the incidence of late complications occurring ‡2 years after allogeneic hematopoietic stem cell transplantation (HSCT) for malignant diseases using a T-cell depletion strategy. Methods: Between 1984 and 2004, 142 patients were eligible for the study. Total body irradiation (TBI) was carried out in 85% of the patients and T-cell depletion in 84%. Results:Non-relapse mortality (NRM) was 3% (95% CI 0–11) at 10 years, and serious late events affected a substantial number of patients. The cumulative incidence (CI) of chronic graft-versus-host disease (cGvHD) was 30% (95% CI 23–40), and that of infectious complications was 17% (95% CI 11–23). Multivariate analysis showed a higher risk for late complications in patients with cGvHD (HR 1.9, 95% CI 1.2–3.2, P = 0.011) and patients receiving methylprednisolone during conditioning (HR 1.9, 95% CI 1.1–3.3, P = 0.019 1), patients with cGvHD also having a higher risk for NRM (HR 13.2, 95% CI 1.2–143, P = 0.03), as well as those receiving steroids for >3 months (HR 40.3, 95% CI 2.3–718, P = 0.02) and those receiving antithymocyte globulin (HR 9.6, 95% CI 0.8–68, P = 0.024). Conclusions: A significant proportion of long-term survivors of HSCT had late complications. cGvHD remained an important risk factor for late complications despite T-cell depletion resulting in immuno suppression and infectious complications.
