Brief summary

Leukaemia is a major disease that seriously endangers human health, the long-term survival rate of acute myeloid leukaemia receiving conventional chemotherapy is only 10% to 45%, haematological relapse is the main cause of treatment failure in acute myeloid leukaemia, reducing the relapse rate is the key to improving the efficacy of acute leukaemia, biomarker-guided preemptive therapy is an effective way to reduce the recurrence of leukaemia, existing markers to predict the recurrence has a high false Existing markers have high false-negative and false-positive rates for predicting relapse, and improving the accuracy of leukaemia relapse prediction is a major clinical problem that needs to be solved urgently. The group has found that circulating leukaemia stem cells remaining after chemotherapy are the key to relapse, therefore, we propose to conduct a multicentre prospective clinical study on the prediction of acute leukaemia relapse by circulating leukaemia stem cells.

Design outcomes

Primary

MeasureTime frameDescription
The primary end point was cumulative incidences of relapse (CIR)2 yearsRelapse 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 diagnosis to the date of disease recurrence. Patients exhibiting minimal residual disease were not classified as having relapsed.

Secondary

MeasureTime frameDescription
Leukemia free survival (LFS)2 yearsLeukimia-free survival was defined as days from diagnosis to disease progression after transplantation.
Overall survival (OS)2 yearsOverall survival referred to patients who survived until the final follow-up time point.
Acute GVHD2 yearsAcute GVHD was defined and graded from 0 to IV based on the pattern and severity of organ involvement\[Sullivan KM. Graft-versus-host-disease. In: Thomas ED, Blume KG, Forman SJ (eds). Hematopoietic Cell Transplantation. 2nd edn. Blackwell Science: Boston, MA, USA, 1999, pp 515-536.\]; grades III-IV aGVHD manifest as serious clinical features on the skin, liver and/or gut.
Transplant related mortality (TRM)2 yearsTransplant-related mortality was defined as all causes of death other than those related directly to malignant disease itself, occurring at any time after transplantation.
Chronic GVHD2 yearsChronic 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.
Non-relapse mortality (NRM)2 yearsNon-relapse mortality was defined as all causes of death other than those related directly to malignant disease itself, occurring at any time after CR.
