Outcomes after allogeneic hematopoietic stem cell transplantation in acute myeloid leukemia patients with der(1;7)(q10;p10)

Abstract The prognosis of acute myeloid leukemia (AML) patients with der(1;7)(q10;p10) who underwent allogeneic hematopoietic stem cell transplantation (allo‐SCT) is unclear due to its rarity. We retrospectively analyzed 151 AML patients with der(1;7)(q10;p10) and compared the findings with those of 853 AML patients with monosomy 7 or chromosome 7q deletion (‐7/del(7q)) using Japanese nationwide registry data. The der(1;7)(q10;p10) group showed significantly better transplant outcomes than the ‐7/del(7q) group. In the multivariate analysis of the der(1;7)(q10;p10) group, additional chromosomal abnormalities and a poor performance status significantly influenced the survival. In conclusion, allo‐SCT is a feasible treatment option for AML patients with der(1;7)(q10;p10).
