What is M7 AML?

Acute Megakaryoblastic Leukaemia (AML, M7) is a rare type of acute myeloid leukemia (AML) evolving from primitive megakaryoblasts. It accounted for 1.2% of newly diagnosed AML according to Eastern Cooperative Oncology Group (ECOG) trials between 1984 and 1997.

How do you treat AML M7?

Treatment includes intensive multidrug chemotherapy and allogeneic bone marrow transplantation. Nevertheless, outcome of AML remains poor with an overall survival of 35-60%. Patients with AML-M7 have a dismal prognosis, which is not the case for children with Down syndrome suffering from AML.

What causes megakaryocytic leukemia?

Pathophysiology. Adult-AMKL can result from the progression of other myeloproliferative neoplasms (MPN) viz., chronic myelogenous leukemia, polycythemia vera, essential thrombocytosis, and primary myelofibrosis. In one review of adult-AMKL, 25% of 49 cases were considered as secondary to one of these MPN.

What is AML with monosomy 7?

Acute myeloid leukemia (AML) with monosomy 7 is associated with poor disease-free survival when treated by aggressive conventional chemotherapy alone. Similarly, outcomes are poor in children with myelodysplastic syndrome (MDS) with monosomy 7 treated by chemotherapy, immunosuppressive drugs or supportive measures.

What is Inv test?

The Inv(16), CBFB-MYH Mutation Analysis Test is a genetic test that detects the inv(16), CBFB-MYH mutation. It is used to diagnose AML subtype M4Eo. It also aids in the treatment of AML by guiding selection of therapeutic drugs, including disqualifying certain drugs from use.

Is AML curable?

Although AML is a serious disease, it is treatable and often curable with chemotherapy with or without a bone marrow/stem cell transplant (see the Types of Treatment section).

What is the life expectancy of someone with acute myeloid leukemia?

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people 20 and older with AML is 26%. For people younger than 20, the survival rate is 68%.

What is Monoblastic leukemia?

Acute monoblastic and monocytic leukemia are myeloid leukemias in which the peripheral blood or bone marrow has greater than or equal to 20% blasts (including promonocytes) and in which greater than or equal to 80% of the leukemic cells are of monocytic lineage, including monoblasts, promonocytes, and monocytes; a …

What does Amkl mean?

Acute megakaryoblastic leukaemia (AMKL) is a rare subtype of acute myeloid leukaemia (AML). It is more common in children than in adults. In children with Down syndrome, AMKL is the most common type of AML.

What happens if you are missing chromosome 7?

A loss of part or all of one copy of chromosome 7 is common in myelodysplastic syndrome, which is a disease of the blood and bone marrow. People with this disorder have an increased risk of developing leukemia.

How common is monosomy 7?

In large multicenter cohorts of children and young adults, monosomy 7 is found in approximately 20% of individuals with MDS and 5% of individuals with AML [Wlodarski et al 2018].
