Résumé
Progression of Philadelphia-negative myeloproliferative (MPN) or myelodysplastic/myeloproliferative neoplasms (MDS/MPN) to acute myeloid leukemia (AML) is an adverse event in the course of the disease. Although allogeneic hematopoietic SCT (allo-SCT) is considered as the only curative therapy, few data exist on the outcome of patients with Philadelphia-negative MPN or MDS/MPN in blast phase who received an allo-SCT. Sixty patients were included in this retrospective study. AML was secondary to an MPN in 43 cases, whereas AML evolved from an MDS/MPN in 17 cases. Patients received allo-SCT in CR or advanced disease in 26 cases and 34 cases, respectively. With a median follow-up of 31 months (range, 25-44), OS and leukemia-free survival (LFS) were, respectively, 18% and 9% at 3 years. CR at transplant was associated with an improved LFS in univariate and multivariate analysis. The 3-year LFS was 18% for patients undergoing allo-SCT in CR versus 3% in advanced disease (P=0.008). Absence of thrombosis and an intermediate or favorable AML karyotype were associated with an improved outcome for patients who received allo-SCT in CR. New strategies are needed to improve the outcome of patients with MPN-MDS/MPN in blast phase.
