Abstract

Objective

We investigated the role of anti-thymocyte globulin (ATG; Thymoglobulin) in matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT) after reduced intensity conditioning (RIC) in myelodysplastic syndrome (MDS).

Methods

Forty-seven patients with 10 mg/kg ATG (ATG group; median age 53 years) and 33 without ATG (no-ATG group; median age 43, P < .0001) were compared.

Results

Median time to engraftment was similar. Two-year cumulative incidence of moderate-to-severe chronic graft-versus-host disease (GVHD) was significantly lower in the ATG group (15% vs 55%, P < .0001), while that of acute GVHD was similar compared with the no-ATG group. After a median follow-up of 60 months (range, 14-184), the 3-year cumulative incidences of non-relapse mortality and relapse were 9% and 21% for ATG group and 15% and 19% for no-ATG group (P = .408 and P = .717), respectively, leading to a significantly better 3-year GVHD-free and relapse-free survival (GRFS) in the ATG group (55% vs 19%, P = .006): The 3-year overall and disease-free survival were similar. Infectious complication occurred with similar frequencies in both groups.

Conclusion

These findings suggest that ATG can be safely used to decrease moderate-to-severe chronic GVHD with improved GRFS for patients with MDS receiving MSD-HSCT in RIC setting.
