Objectives

Narrative objectives1

The objectives of this study are to determine the incidence, risk factors, response to therapy and long-term outcome in patients with therapy-related acute promyelocytic leukemia (tAPL) from the JALSG observation studies. Our aim is also to analyze the impact of additional cytogenetic abnormalities and the role of hematopoietic stem cell transplantation (HSCT) in patients with t-APL.

Basic objectives2

Others

Basic objectives -Others

Overall survival rate in patients with t-APL. Compare the survival between t-APL and de novo cases.

Assessment

Primary outcomes

Overall survival (OS) rates in patients*1 with t-APL and de novo APL, respectively.

Key secondary outcomes

1. Complete remission (CR) rates (*1)
2. Relapse free survival (*1)
3. Cumulative incidence of relapse (*1)
4. Comparison of OS, disease free survival (DFS) and event free survival (EFS)*2 between t-APL and de novo APL
*2: Event is defined as failure to achieve CR, relapse including molecular relapse, or death from any cause.
5. Age, gender, ECOG PS and additional chromosomal abnormalities of onset of APL (*1)
6. Backgrounds before the onset of t-APL: primary neoplasm, previous therapy, treatment effect, and latency period to the occurrence of t-APL
7. Comparison of clinical data and biological characteristics between therapy-related and de novo patients at the time of initial diagnosis of APL
8. Implementation status of actual administration of the chemotherapy drugs. Rates of complete remission and safety profile and grades. Incidence and outcome of hematopoietic stem cell transplantation (HSCT: allogeneic- and/or autologous-). Efficacy and safety of HSCT, such as treatment related mortality, relapse, engraftment, acute graft versus host disease (GVHD), chronic GVHD, and so on (*3).
*3: These are the data from the Japan Society for Hematopoietic Cell Transplantation Transplant Registry Unified Management Program (TRUMP) database.
9. Association of known prognostic factors for de novo APL with prognosis in t-APL. Exploration of new prognostic factors in t-APL. Feasibility of classification according to these prognostic factors.
10. Long-term outcomes (OS, DFS, and EFS)
