What is Acute Myeloid Leukemia (AML) with Maturation?

Acute myeloid leukemia with maturation, also known as AML-M2, is a subtype of acute myeloid leukemia (AML). It is characterized by the presence of immature and mature myeloid cells in the bone marrow or blood.

Key Features:

• Presence of > 20% blasts: AML-M2 is defined by the presence of more than 20% blast cells in the bone marrow or blood.
• Maturation stages: The disease is characterized by the maturation stages of myeloid cells, which are cells that normally develop into red blood cells, white blood cells, and platelets.

Symptoms:

• Fever
• Pain: Common places for pain include the bones, back, and stomach.
• Fatigue: Feeling very tired.
• Paleness or change in skin color

Causes and Development:

• Myeloid stem cells: Myeloid stem cells go through several stages of development in the bone marrow before fully maturing into red blood cells, white blood cells, and platelets.
• Abnormal cell growth: In AML-M2, there is abnormal growth of myeloid cells, which can lead to an accumulation of immature and mature cells in the bone marrow or blood.

Acute Myeloid Leukemia (AML) with maturation is a type of blood cancer that affects the bone marrow's ability to produce healthy blood cells. The signs and symptoms of AML with maturation can vary from person to person, but common ones include:

• Fever: Many people with AML experience recurring fevers, which can be a sign of an infection or inflammation in the body [1].
• Fatigue: Feeling extremely tired or weak is another common symptom of AML with maturation. This can be due to the cancer cells crowding out healthy blood cells and affecting the body's ability to produce energy [5].
• Easy bruising or bleeding: People with AML may experience easy bruising or bleeding, which can be a sign that their platelet count is low [4].
• Pale skin: Some individuals with AML may appear pale due to a lack of red blood cells in the body [1].
• Bone pain or tenderness: Pain or tenderness in the bones, back, and stomach are also possible symptoms of AML with maturation [2].

It's essential to note that these symptoms can be similar to those experienced by people with other conditions. If you're experiencing any of these symptoms, it's crucial to consult a healthcare provider for proper diagnosis and treatment.

Diagnostic Tests for Acute Myeloid Leukemia (AML) with Maturation

Acute myeloid leukemia with maturation is a subtype of AML that can be diagnosed through various tests. Here are some of the diagnostic tests used to confirm this condition:

• Blood tests: Blood tests, including complete blood counts (CBCs), are typically done to diagnose AML with maturation. These tests help identify abnormal white blood cells and their characteristics [1].
• Bone marrow aspiration and biopsy: Bone marrow aspiration and biopsy are considered the definitive diagnostic tests for AML with maturation. These procedures involve removing a sample of bone marrow from the hipbone using a needle, which is then examined under a microscope to look for cancerous cells [3].
• Genetic analysis: Genetic analysis is also used to identify specific genetic abnormalities associated with AML with maturation. This test helps determine the subtype of AML and guide treatment decisions [4].
• Imaging tests: Imaging tests, such as X-rays or CT scans, may be done to rule out other conditions that can cause similar symptoms [8].

Additional Diagnostic Tests

In some cases, additional diagnostic tests may be necessary to confirm the diagnosis of AML with maturation. These tests may include:

• Routine bone marrow exam during first remission of acute myeloid leukemia
• Additional diagnostic tests for AML without maturation

It's essential to consult a healthcare provider for accurate and personalized information on diagnosing and treating AML with maturation.

Treatment Options for Acute Myeloid Leukemia (AML) with Maturation

Acute myeloid leukemia (AML) with maturation, also known as AML-M2, is a type of blood cancer that affects the bone marrow's ability to produce healthy blood cells. The treatment options for AML with maturation are similar to those for other types of AML.

Chemotherapy

Chemotherapy is a common treatment approach for AML with maturation. It involves using medications to kill cancer cells in the bone marrow and bloodstream. Chemotherapy can be given as an outpatient procedure or as part of a hospital stay [10].

Targeted Therapy

Targeted therapy, also known as molecularly targeted therapy, uses medications that specifically target the genetic mutations responsible for AML with maturation. For example, venetoclax (Venclexta) targets BCL-2, a protein in cancer cells that helps them live longer than they should [2].

Stem Cell Transplant

A stem cell transplant is a treatment option for some patients with AML with maturation. This procedure involves replacing the patient's bone marrow with healthy stem cells from a donor or the patient themselves [10].

Other Treatment Options

Other treatment options for AML with maturation include radiation therapy, which uses high-energy rays to kill cancer cells, and other medications such as azacytidine and decitabine. The choice of treatment depends on various factors, including the patient's age, overall health, and specific characteristics of their leukemia [10].

The differential diagnosis of acute myeloid leukemia (AML) with maturation, also known as AML-M2, involves distinguishing it from other hematologic malignancies that may present with similar symptoms and characteristics.

According to the search results, the differential diagnosis of AML includes:

• Acute lymphoblastic leukemia (ALL), which can be distinguished by the presence of lymphoid markers [8].
• AML without maturation, which is characterized by a high percentage of blasts but lacks most markers of myeloid and monocytic maturation [8].
• Acute monoblastic leukemia (M5a), which is a subtype of acute myeloid leukemia that is distinguished by the presence of monoblasts in the bone marrow [8].
• Acute megakaryoblastic leukemia, which is a rare subtype of acute myeloid leukemia characterized by the proliferation of megakaryocytes [8].

Additionally, AML with maturation can be distinguished from other subtypes of AML based on the presence or absence of specific markers. For example, most cases express early hematopoiesis-associated antigens (eg, CD34, CD38, and HLA-DR) and lack most markers of myeloid and monocytic maturation [7].

It's worth noting that the differential diagnosis of AML with maturation is a complex process that requires careful examination of clinical and laboratory findings. The underlying pathophysiology in AML consists of clonal expansion and arrested maturation of hematopoietic stem cells and progenitor cells, which can lead to a variety of subtypes and presentations [6].
