Annen: Age-Stratified Conditioning Regimen
MDS patients without identical sibling donor or unrelated donor would receive haplo-HSCT.
Participants will receive either reduced-toxicity Bu/Flu/Cy/ATG conditioning regimen (for patients aged ≥55 years) or standard myeloablative modified Bu/Cy+ATG conditioning regimen (for patients aged <55 years) followed by unified post-transplant immunosuppression and supportive care.
|
RTC preconditioning regimen consisted of cytarabine (2g/m2/day, days -10 to -9), busulfan (3.2 mg/kg/day on days -8 to -6), cyclophosphamide (1.0 g/m2/day, days -5 to -4), fludarabine (30 mg/m2/day, days -6 to -2), semustine (250 mg/m2, day-3), and rabbit antithymocyte globulin (thymoglobulin, 2.5 mg/kg/d, days -5 to -2; Sanofi, France).
Bu/Cy preconditioning regimen consisted of tandard institutional myeloablative busulfan + cyclophosphamide + rabbit ATG regimen per department routine dosing guidelines.

Tidsramme |
|---|---|---|
|
Hematopoietic engraftment
Tidsramme: Day 30 and Day 90 post-transplantation
|
Neutrophil engraftment is defined as the first day of sustained absolute neutrophil count (ANC) ≥0.5×10⁹/L for 3 consecutive days; platelet engraftment is defined as the first day of sustained platelet count (PLT) ≥20×10⁹/L without transfusion support for 7 consecutive days.
Cumulative incidence of neutrophil engraftment at Day 30 and platelet engraftment at Day 90 will be calculated.
|
Day 30 and Day 90 post-transplantation
|
|
Cumulative incidence of graft-versus-host disease (GVHD)
Tidsramme: Day 100 and 3 years after transplantation
|
Cumulative incidence of Grade II-IV and Grade III-IV acute GVHD at Day 100, as well as chronic GVHD and moderate-severe chronic GVHD within 3 years after transplantation, graded per Seattle criteria.
|
Day 100 and 3 years after transplantation
|
|
Cumulative incidence of CMV and EBV reactivation
Tidsramme: 1 year after transplantation
|
Defined as any detectable CMV or EBV viral load elevation requiring clinical intervention within 1 year after transplantation.
|
1 year after transplantation
|
|
Cumulative incidence of hematologic relapse
Tidsramme: 1 year after transplantation
|
Defined as bone marrow blast recurrence or extramedullary disease relapse within 1 year after transplantation.
|
1 year after transplantation
|
|
Disease-free survival (DFS)
Tidsramme: 1 year after transplantation
|
Defined as the time from transplantation until hematologic relapse or death from any cause.
|
1 year after transplantation
|
|
Overall survival(OS)
Tidsramme: 1 year after transplantation
|
Defined as the time from treatment until death from any cause or the last follow-up.
|
1 year after transplantation
|
|
Conditioning-related organ toxicities
Tidsramme: From conditioning start to Day 30 post-transplantation
|
Incidence of grade 1-4 cardiac, renal, hepatic, gastrointestinal and oral mucosal toxicities from conditioning initiation to Day +30 post-transplantation, with separate analysis of Grade 3-4 severe organ injury, hepatic veno-occlusive disease (VOD), and conditioning-related death, graded per WHO organ toxicity scale.
