Survival after AHSCT with a FluMel conditioning regimen in MF patients. Cumulative OS (A) and EFS (B) in 32 MF patients who received a transplant from a sibling donor. Median survival has not been reached, because 75% of patients were alive at last follow-up and 71% were without disease progression. Cumulative OS (C) and EFS (D) in 34 MF patients who received a transplant from an unrelated donor. Median OS and EFS in unrelated transplants are shown.
