Abstract

BACKGROUND:

Allogeneic hematopoietic stem cell transplantation (alloHSCT) is often performed in cases of advanced hematological diseases, but because of the associated mortality and a high risk of relapse it is life prolonging only in some patients.

PATIENTS AND METHODS:

A retrospective multi-center analysis of 401 patients was conducted to analyze the variables associated with outcome after alloHSCT in advanced hematological diseases. The Cox proportional hazards model was used to assess the independence of overall survival (OS) and disease-free survival (DFS) from prognostic factors in a multivariate model.

RESULTS:

The 5-year OS and DFS were 27.3 and 21.1% respectively. Multivariate analysis showed that the underlying malignancy had a significant influence on OS and DFS (p < 0.001 and p < 0.011, respectively), whereas development of severe acute graft versus host disease (GvHD) had a negative impact on OS (p < 0.001). Development of chronic GvHD showed a trend to a better OS (p = 0.085) and DFS (p = 0.199). No impact was seen for the intensity of conditioning.

CONCLUSION:

Development of chronic GvHD but not the conditioning regimen improved the outcome after alloHSCT for advanced malignancies, underlining the importance of immunological rather than cytotoxic effects.
