Outcome Measures

Primary Outcomes (1)

  • Incidence of Systemic Mastocytosis associated with t(8;21) Acute Myeloid Leukemia

    Evaluation of the incidence of systemic mastocytosis associated with t(8;21) AML in patients with de novo t(8;21) AML. The incidence of systemic mastocytosis associated with t(8;21) AML will be evaluated by means of the number of diagnosis of systemic mastocytosis associated with t(8;21) AML on the number of all diagnoses of de novo t(8;21) AML between September 2022 and August 2023.

    at 1 year

Secondary Outcomes (4)

  • Hematological characteristics of all the t(8;21) Acute Myeloid Leukemia

    at 1 year

  • Responses to the first induction therapy of all the t(8;21) Acute Myeloid Leukemia

    at 1 year

  • Incidence of transplantation of all the t(8;21) Acute Myeloid Leukemia

    at 1 year

  • Survival Distribution of all the t(8;21) Acute Myeloid Leukemia

    at 2 years

Study Arms (3)

Systemic Mastocytosis with associated t(8;21) AML

SM and AML were diagnosed according to the 5th edition WHO classification criteria.

The t(8;21) AML without Systemic Mastocytosis

The t(8;21) AML patients do not have associated Systemic Mastocytosis according to the 5th edition WHO classification criteria and no AML1-ETO clone was detected in mast cells.

OSM (Oligo-mastocytic SM) with associated t(8;21) AML

The t(8;21) AML patients do not have associated Systemic Mastocytosis according to the 5th edition WHO classification criteria, but AML1-ETO clones were detected in mast cells.
