Advances in Stem Cell Transplantation for Myelofibrosis.

PURPOSE OF REVIEW: Allogeneic hematopoietic cell transplantation is the only potentially curative treatment for myelofibrosis. This review discusses issues not well-covered by existing guidelines: timing of transplant, pre-transplant spleen management and alternative donors; providing our approach to these situations.

RECENT FINDINGS: Research continues to allow better identification, by better risk stratification and advances in understanding likelihood of durable JAKi response, which patients are likely to derive benefit from upfront transplant versus those for whom delayed transplant may be more appropriate. Several options of JAKi therapy provide a non-surgical option for pre-HCT splenomegaly management, allowing some patients to avoid risks associated with splenectomy. Recent years have also seen a sharp spike in haploidentical donor transplants, along with narrowing of the gap in outcomes between donor types. Continuous enrollment in prospective studies or well-designed registries is required to generate the high-quality data needed to develop better decision tools for these scenarios.
