Post-transplant ring sideroblasts are common in haploidentical peripheral blood stem cell transplantation but not linked to SF3B1 mutations

Key Points

• This research aims to explore the prevalence of ring sideroblasts after haploidentical peripheral blood stem cell transplantation and their association with SF3B1 mutations.
• Analyzed erythroid dysplasia and ring sideroblasts prevalence in haploidentical PBST.
• Compared findings with SF3B1 mutations and assessed prognostic significance.
• Erythroid dysplasia and ring sideroblasts occurred significantly more after haploidentical PBSCT.
• No link between ring sideroblasts and SF3B1 mutations was found.
• Post-transplant outcomes remained influenced primarily by transplant modality and patient age.
