Study Notes
Diagnosis
- Acute Myeloid Leukemia (AML) diagnosis involves a combination of:
- Physical examination
- Medical history
- Laboratory tests:
- Complete Blood Count (CBC) to evaluate blood cell counts
- Blood smear to examine blood cell morphology
- Bone marrow biopsy to examine bone marrow cells
- Immunophenotyping to identify specific cell surface markers
- Genetic testing to identify specific mutations (e.g., FLT3, NPM1)
- Diagnosis is typically confirmed by:
- Presence of 20% or more blast cells in the bone marrow
- Detection of specific genetic mutations
Treatment Options
- Treatment goals:
- Induction therapy: achieve remission
- Consolidation therapy: maintain remission
- Maintenance therapy: prevent relapse
- Treatment options:
- Chemotherapy:
- Combination of cytotoxic drugs (e.g., cytarabine, daunorubicin)
- Targeted therapy (e.g., FLT3 inhibitors)
- Supportive care:
- Blood transfusions
- Infection management
- Stem cell transplantation (see below)
- Chemotherapy:
Stem Cell Transplantation
- Autologous stem cell transplantation:
- High-dose chemotherapy followed by infusion of patient's own stem cells
- Aims to remove cancer cells and restore healthy bone marrow
- Allogenic stem cell transplantation:
- High-dose chemotherapy followed by infusion of donor stem cells
- Aims to replace cancer cells with healthy donor cells
- Stem cell transplantation can be:
- Myeloablative (high-dose chemotherapy)
- Non-myeloablative (lower-dose chemotherapy)
Risk Factors
- Increased risk of AML:
- Age (risk increases after 60)
- Genetic mutations (e.g., Down syndrome, Fanconi anemia)
- Exposure to:
- Radiation (e.g., radiation therapy)
- Chemicals (e.g., benzene)
- Previous chemotherapy or radiation therapy
- Family history of AML
Symptoms
- Common symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Easy bruising or bleeding
- Frequent infections
- Weight loss
- Enlarged lymph nodes or spleen
- Symptoms may vary depending on the location and extent of cancer cell infiltration

- Exposure to:
- Radiation (e.g., radiation therapy)
- Chemicals (e.g., benzene)
- Previous chemotherapy or radiation therapy
- Family history of AML
Symptoms
- Common symptoms of AML include:
- Fatigue
- Weakness
- Shortness of breath
- Easy bruising or bleeding
- Frequent infections
- Weight loss
- Enlarged lymph nodes or spleen
- Symptoms may vary depending on the location and extent of cancer cell infiltration
Treatment Options
- Chemotherapy is the most common treatment for AML, aiming to kill cancer cells
- Induction chemotherapy involves cytarabine and anthracycline (daunorubicin or idarubicin) to induce remission
- Consolidation chemotherapy involves high-dose cytarabine to prevent relapse
- Stem cell transplant can be autologous or allogeneic, replacing cancerous bone marrow with healthy stem cells
- Targeted therapy inhibits specific proteins or genes involved in AML
- FLT3 inhibitors (e.g., midostaurin) are used for FLT3-mutated AML
- IDH1/2 inhibitors (e.g., ivosidenib) are used for IDH1/2-mutated AML
- Supportive care manages symptoms and side effects, including blood transfusions, antibiotics, and pain management
Symptoms
- Fatigue is a common symptom of AML
- Shortness of breath is a common symptom of AML
- Easy bruising or bleeding is a common symptom of AML
- Frequent infections are a common symptom of AML
- Weight loss is a common symptom of AML
- Bone pain is a less common symptom of AML
- Swollen lymph nodes are a less common symptom of AML
- Enlarged liver or spleen are less common symptoms of AML
- Confusion or dizziness are less common symptoms of AML
- Headaches or seizures are rare symptoms of AML
Diagnosis
- Complete Blood Count (CBC) evaluates blood cell counts
- Peripheral blood smear examines blood cells
- Bone marrow biopsy examines bone marrow cells
- Fluorescence in situ hybridization (FISH) detects chromosomal abnormalities
- Polymerase chain reaction (PCR) detects genetic mutations
- CT or PET scans evaluate organ involvement or detect extramedullary disease
- X-rays evaluate bone involvement
