Predictive Value of Myelodysplastic Syndrome Stem Cells Determined by Multiparameter Flow Cytometry

February 22, 2026 updated by: Chang Yingjun, Peking University People's Hospital

Predictive Value of Myelodysplastic Syndrome Stem Cells Determined by Multiparameter Flow Cytometry in Patients Receiving Allotransplantation: a Multi-center, Prospective Clinical Study

Presently, multiparameter flow cytometry (MFC) and polymerase chain reaction (PCR) have been used for disease load, including measurable residual disease (MRD), monitoring in patients with myelodysplastic syndrome (MDS). MFC is the most commonly method for disease load evaluation. In patients with acute myeloid leukemia, leukemia stem cells (LSCs) determined using MFC for leukemia load and MRD detection is superior to traditional MFC method. In the investigators previous single center study, the investigators demonstrated that detection of disease load, including MRD, by MFC in patients with MDS-EB is superior to predict outcomes after allogeneic stem cell transplantation. Here, the investigators will perform a multi-center, prospective clinical trial to investigate the predictive values of MDS-SC in patients with MDS-EB who received allografting.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

To determine whether there was any difference in relapse between the pre-transplant MRD-positive and -negative groups, the cumulative incidence approach was used with a test for equivalence of CIF for the difference in the Kaplan-Meier estimate of the 1-year CIR. With a planned sample size of 163 AML/MDS patients, 80% power can be achieved against the hypothesis of CIR as 18.3% and 3.6% for cases in the pre-transplant MRD-positive and -negative groups at a significance level of P = 0.05 in Student's one-tailed t-test.

Description

Inclusion Criteria:

  • Patients with Myelodysplastic syndromes;
  • Between 15 and 70 years old;
  • Subjects are able to provide written informed consent.

Exclusion Criteria:

  • Subjects who cannot comply with the study;
  • Patient has severe cardiac (ejection fraction <50%), hepatic (total bilirubin >34μmol/L, ALT, AST >2x upper limit of normal) or renal (blood creatinine >130μmol/L) disease；
  • Uncontrolled serious infection;
  • Other conditions that do not tolerate transplantation or other therapies.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
1 year-cumulative relapse rate
Time Frame: through study completion, an average of 1 year
Relapse was defined by the morphological evidence of disease in the peripheral blood, BM or extramedullary sites. Time to relapse was defined from the date of transplantation to the date of disease recurrence. Patients exhibiting minimal residual disease were not classified as having relapsed.
through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cumulative positive rate of measurable residual disease (MRD) after transplantation
Time Frame: through study completion, an average of 1 year
The proportion of MRD positive patients after treatment.
through study completion, an average of 1 year
Disease-free survival (LFS)
Time Frame: through study completion, an average of 1 year
Disease-free survival was defined as days from transplantation to disease progression after transplantation.
through study completion, an average of 1 year
Overall survival (OS)
Time Frame: through study completion, an average of 1 year
Overall survival referred to patients who survived until the final follow-up time point.
through study completion, an average of 1 year
Non-recurrent death (NRM)
Time Frame: through study completion, an average of 1 year
Non-recurrent mortality was defined as all causes of death other than those related directly to malignant disease itself, occurring at any time after CR.
through study completion, an average of 1 year
Transplant-related death (TRM)
Time Frame: through study completion, an average of 1 year
Transplant-related death was defined as all causes of death other than those related directly to malignant disease itself, occurring at any time after transplantation.
through study completion, an average of 1 year
Acute graft-versus-host disease (GVHD)
Time Frame: through study completion, an average of 1 year
Acute GVHD was defined and graded from 0 to IV based on the pattern and severity of organ involvement; grades III-IV aGVHD manifest as serious clinical features on the skin, liver and/or gut.
through study completion, an average of 1 year
Chronic graft-versus-host disease (GVHD)
Time Frame: through study completion, an average of 1 year
Chronic GVHD was defined and graded according to the National Institute of Health criteria:[Biol Blood Marrow Transplant,2005,11: 945] that is, mild cGVHD reflects the involvement of no more than 1 or 2 organs/sites (except for lung) with a maximum score of 1; moderate cGVHD involves at least 1 organ/site with a score of 2 or ≥3 organs/sites with a score of 1 (or lung score 1); and severe cGVHD is diagnosed when a score of 3 is given to any organ (or lung score 2). The diagnosis is mainly based on clinical manifestations.
through study completion, an average of 1 year
