Summary
Brief summary (as posted)
The investigators will evaluate the outcomes of allogeneic stem cell transplantation which is the only curative treatment modality in the patients with chronic myeloid leukemia after failing tyrosine kinase inhibitor therapy. However, any update was not reported on the transplant outcomes in the patients failed TKI therapy, thus necessitating update of this data. Also, the European Group for Blood and Marrow Transplantation (EBMT) risk score is still of value, but insufficient numbers of patients have been transplanted in recent years and after TKI therapy to allow a robust reanalysis. Our study hypothesis is that allogeneic SCT treatment modality can rescue CML patients who failed TKI therapy due to resistance or to intolerance with improved survival and long-term outcomes. Also, another hypothesis will be examined if the EBMT risk score proposed pre-imatinib era can reproduce similar prognostic risk stratification of long-term outcomes in the patients treated with TKI.

[]Primary outcomes (1)
- measure
- Overall survival following allogeneic SCT for CML after TKI failure.
- timeFrame
- at 3 years
- description
- Overall survival will be calculated from transplantation until the date of death from any cause or of latest follow-up
Secondary outcomes (2)
- measure
- Failure free survival following allogeneic SCT for CML after TKI failure
- timeFrame
- at 3 years
- description
- Time to failure free survival is defined as the interval between transplantation and treatment failure. Treatment failure will be defined as primary hematologic resistance, cytogenetic resistance, loss of CCyR, development of ABL tyrosine kinase domain mutation, clonal evolution and progression to accelerated phase (AP) or blastic crisis (BC).
- measure
- Relapse following allogeneic SCT for CML after TKI failure
- timeFrame
- at 3 years
