Diagnosis, HLA matching, JAK2^V617F, and age do not correlate with survival after AHSCT with a FluMel conditioning regimen in MF patients. OS in recipients with grafts from sibling (Sib) and unrelated (Unrel) donors based on diagnosis (PMF, ET-MF, or PV-EF) (A), HLA-matched or HLA-mismatched donor (B) (*2/32 patients in the HLA-matched Sib group received a 1-antigen-mismatched transplant from their sibling, and none of them died), presence of JAK2^V617F mutation (Jak2 pos) (C), and age < or ≥57 years (D).
