Haplo-HSCT for Myelofibrosis

"This is a single-arm study in which all patients will undergo haploidentical hematopoietic stem cell transplantation for the treatment of myelofibrosis.~Pre-transplant Evaluation:~Evaluation includes status of primary Disease, donor specific antibodies (DSA), organ function (assessments for heart, liver, lungs, kidneys, and the nervous system), and Spleen size.~Transplantation Protocol:~Conditioning Regimen:~Dac/TT/Bu/Flu/ATG regimen:~Decitabine 100 mg/m², on day -12. Thiotepa (TT) 5 mg/kg/day, on days -11 and -10. Busulfan 0.8 mg/kg body weight, every 6 hours, on days -8 to -6. Fludarabine 30 mg/m², once daily, on days -6 to -2. Anti-thymocyte globulin (ATG) 2.5 mg/kg body weight, once daily, on days -5 to -2.~Transplant Donor: Haploidentical donor. GVHD (Graft-versus-Host Disease) Prophylaxis Regimen: Cyclosporine, mycophenolate mofetil, and short-course methotrexate for GVHD prevention.~Graft:~Target MNC (Mononuclear Cells): 6-8 × 10⁸/kg. Target CD34+ stem cells: 5 × 10⁶/kg"
