Objectives

Narrative objectives1

This is a multicenter prospective observational study based on a centralized registry that collects clinical and biomarker data from patients with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), or chronic myelomonocytic leukemia (CMML) diagnosed at institutions participating in the Japan Adult Leukemia Study Group (JALSG). The study aims to determine the 3- and 5-year survival rates and to evaluate the associations between treatment outcomes, treatment strategies, and patient-related factors such as age and comorbidities.

Basic objectives2

Others

Basic objectives -Others

In addition to assessing overall survival in all registered patients, the primary objective is to collect data on factors potentially associated with treatment outcomes, including (1) disease characteristics at diagnosis, including hematologic malignancy panel testing results; (2) treatment regimens used in real-world clinical practice; (3) the use of novel agents such as venetoclax, gemtuzumab ozogamicin (GO), azacitidine, lenalidomide, FLT3 inhibitors, CPX-351, and IDH inhibitors, as well as supportive therapies including iron chelation and erythropoiesis-stimulating agents; (4) allogeneic hematopoietic stem cell transplantation; (5) comorbidities; and (6) geriatric-specific factors, in order to generate evidence that may contribute to improving future prognosis.

Assessment

Primary outcomes

Overall survival of patients with AML, MDS, or CMML

Key secondary outcomes

Initial treatment efficacy and remission rates by treatment type for AML, MDS, and CMML
Relapse-free survival by AML, MDS, and CMML
Impact of the use of new drugs on survival rates for AML, MDS, and CMML
Impact of the use of supportive care medications on survival rates for AML, MDS, and CMML
Evaluation of causes of death
Survival rates following allogeneic hematopoietic stem cell transplantation, and the relationship between transplantation methods and relapse-free and graft-versus-host disease (GVHD)-free survival rates
Evaluation of transplantation-related complications in allogeneic hematopoietic stem cell transplantation cases
Analysis of risk factors affecting overall survival (OS) (impact of patient background, comorbidities, and concomitant medications on treatment outcomes)
Impact of genetic information on prognosis

Key inclusion criteria

Age >16 years at the time of informed consent.

Newly diagnosed and previously untreated AML (acute myeloid leukemia and related neoplasms), MDS (myelodysplastic syndromes), or CMML (chronic myelomonocytic leukemia) according to the Revised 4th Edition of the WHO Classification.
Patients with acute leukemias of ambiguous lineage (acute undifferentiated leukemia and mixed phenotype acute leukemia [MPAL]) and blastic plasmacytoid dendritic cell neoplasm (BPDCN) are also eligible.
MDS/MPN (myelodysplastic/myeloproliferative neoplasms) other than CMML are excluded.

After receiving a full explanation regarding participation in this study, written informed consent was obtained from the patient (or, in the case of minors or adults with impaired capacity to consent due to cognitive decline, from a legal representative, or from both the patient and the legal representative) based on their full understanding and of their own free will.

Key exclusion criteria

If the principal investigator or a co-investigator determines that participation in this study is inappropriate.
