A Multicenter Randomized Controlled Study of the Effect of Stem Cell Infusion Time on the Development of aGVHD in Patients With Hematological Malignancies After Allogeneic Peripheral Blood Hematopoietic Stem Cell Transplantation
To observe the effect of stem cell infusion on the development of acute graft-versus-host disease (aGVHD) in patients with malignant hematologic diseases after allogeneic peripheral blood hematopoietic stem cell transplantation (allo-PBSCT)
• Definite diagnosis of malignant hematologic disease before transplantation, age 12-60 years old, gender is not limited, race is not limited;
• Patients who are proposed to receive allo-PBSCT for the first time;
• Eastern Cooperative Oncology Group (ECOG) score 0-2;
• No serious organ failure and active infection;
• Voluntary open randomized controlled study to observe whether the time of stem cell infusion affects the occurrence of aGVHD after transplantation;
• Each subject must sign an informed consent form (ICF) indicating that he/she understands the purpose and procedures of the study and is willing to participate in the study; in view of the patient's condition, if the patient's own signature is not conducive to the treatment of his/her condition, the ICF will be signed by the legal representative.
