Allogeneic BMT in patients above 45 years of age : a single center experience

Increasing age has been reported to be associated with worse outcome and higher occurrence of complication after allogeneic bone marrow transplantation. We analysed a cohort of 39 patients between the ages of 45 and 57 (median 49 years) with different hematologic malignancies who had undergone BMT in our institution over the preceding 4 years. Pretransplant conditioning consisted of Bu/CY2, GVHD prophylaxis of a combination of cyclosporine and "short" methotrexate. At present 54% of patients remain alive (with a median follow-up 44 months), the probability of survival at 5 years is 53% (5-year DFS 78%). The 5-year survival probability in the control group of younger patients is 53% (P = 0.8003). Main causes of death were GVHD (4 patients, 10%), relapse (5 patients, 13%) and infection (6 patients, 15%). The incidence of acute GVHD grade II-IV was 51% (grade III-IV 0% patients), the incidence of chronic GVHD 49% (limited 18% and extensive 31% patients). Our results suggest that allogeneic BMT can be performed in patients above the age of 45 years with acceptable morbidity and mortality, especially if a family HLA matched donor is available.
