Acute Myeloid Leukemia With Myelodysplasia(AML-MR)

Acute myeloid leukemia, myelodysplasia-related (AML-MR) is a blood cancer that starts in the bone marrow and produces too many immature white blood cells (blasts). Doctors use the term “myelodysplasia-related” when the leukemia shows strong links to myelodysplastic disease—either because the person previously had MDS or an MDS/MPN overlap, or because the leukemia carries special chromosome changes or specific “MDS-type” gene mutations. Modern classifications (2022 onward) say that seeing abnormal cell shapes alone is not enough; the diagnosis needs history, cytogenetics, and/or gene evidence. A typical feature is ≥20% blasts in the marrow or blood for this category, and it generally behaves more aggressively than some other AML types. College of American PathologistsNature

Acute myeloid leukemia with myelodysplasia-related features (AML-MR) is a fast-growing blood cancer that starts in the bone marrow—the soft center inside bones where new blood cells are made. In AML-MR, the leukemia has signs of previous “wear and tear” in the marrow called myelodysplasia (“dysplasia” means abnormal shape or development). Doctors recognize AML-MR in three main ways:

1. there is clear dysplasia (abnormal look) in blood-forming cells under the microscope,

2. there are chromosome changes known to be linked to myelodysplasia, or

3. the person had past myelodysplastic syndrome (MDS) or a related bone-marrow disease before AML appeared. NCBI

Modern classification systems also let doctors diagnose AML-MR when the leukemia cells carry a specific set of gene mutations that point to “myelodysplasia-related biology.” The most important “MR genes” include ASXL1, BCOR, EZH2, STAG2 and several spliceosome genes (SF3B1, SRSF2, U2AF1, ZRSR2). These mutations are strongly connected to AML that arises from or behaves like MDS and they usually predict higher-risk disease. (Some systems also consider RUNX1.) PMCASH Publications+1

People with AML-MR often have symptoms like tiredness, shortness of breath, frequent infections, bruising or bleeding, because their bone marrow can’t make healthy red cells, white cells, or platelets. AML-MR needs quick, specialist care. Treatments may include chemotherapy, lower-intensity regimens, and sometimes allogeneic stem-cell transplant (a donor marrow transplant) if the person can safely undergo it. One chemotherapy, CPX-351 (liposomal daunorubicin + cytarabine, brand Vyxeos), is specifically approved for AML with myelodysplasia-related changes. FDA Access DataU.S. Food and Drug Administration

Other names

Older or alternate terms include “AML with myelodysplasia-related changes (AML-MRC)”, “MDS-related AML”, “secondary AML from MDS”, and “AML-MR” (current WHO 2022 name). Some expert groups also split AML-MR into sub-sets by cause (mutation-defined, cytogenetic-defined, or with a prior MDS/MDS-MPN history). In 2022 updates, the category name changed from AML-MRC to AML-MR, and “morphology alone” (cell appearance) no longer establishes the diagnosis without the supporting genetic or clinical criteria. College of American Pathologists

Types

Doctors do not divide AML-MR by how the cells look so much as why it’s considered myelodysplasia-related. The main practical “types” are:

1. History-defined AML-MR
   The person previously had MDS or an MDS/MPN (e.g., chronic myelomonocytic leukemia), then progressed to AML with ≥20% blasts.

2. Cytogenetic-defined AML-MR
   The leukemia carries MDS-type chromosome abnormalities (for example, certain losses or complex karyotypes) that strongly point to an MDS background.

3. Mutation-defined AML-MR
   The leukemia has one or more of eight “MR genes” often seen in MDS or in AML that evolved from MDS: SRSF2, SF3B1, U2AF1, ZRSR2, ASXL1, EZH2, BCOR, STAG2. Finding these helps label the case as AML-MR even if the person never had a formal MDS diagnosis before. Nature

Notes: In 2022 updates, RUNX1 mutation was not kept as its own AML entity; and pure “cell dysplasia” without the genetic or history criteria is no longer enough to call AML-MR. Nature

Causes

In simple terms, “causes” here means exposures, backgrounds, or medical states that make AML-MR more likely.

1. Previous MDS – the most direct pathway; many cases arise as the next step after myelodysplastic syndrome.

2. Previous MDS/MPN overlap (e.g., CMML) – these mixed disorders often evolve into AML fitting AML-MR biology.

3. Age-related clonal hematopoiesis – as we age, marrow cells collect mutations; certain clones (e.g., splicing-factor mutations) raise risk of MDS → AML-MR.

4. Specific “MR gene” mutations acquired over time (e.g., SRSF2, U2AF1, SF3B1, ZRSR2, ASXL1, EZH2, BCOR, STAG2) can “set the stage” for MDS-like biology and leukemic transformation. Nature

5. Chromosome 5 or 7 abnormalities in marrow cells (classically seen in MDS) increase risk of transformation to AML-MR.

6. Complex karyotype (many chromosome changes at once) – a hallmark of MDS-like disease that often progresses to AML-MR.

7. Prior cytotoxic chemotherapy (alkylating agents, topoisomerase II inhibitors) for other cancers can produce MDS-like damage that later evolves to AML; when it meets AML-MR criteria, it is labeled with the therapy-related qualifier. College of American Pathologists

8. Radiation exposure (medical or environmental) that damages marrow DNA can drive an MDS → AML-MR pathway.

9. Benzene and industrial solvent exposure – classic marrow toxins linked to MDS and AML risk.

10. Smoking – contributes to DNA damage and marrow mutational burden.

11. Long-standing immune dysregulation or chronic inflammation – can stress bone marrow and promote clonal evolution.

12. Aplastic anemia history – some patients treated for severe marrow failure later develop MDS and AML-MR.

13. Inherited marrow-failure or predisposition syndromes (e.g., GATA2 deficiency, Fanconi anemia, telomere biology disorders) can lead to MDS and then AML-MR in adulthood.

14. Down syndrome (in children) – while its leukemias follow special rules, DS-associated myeloid disease can progress along MDS/AML lines.

15. Exposure to pesticides or heavy metals – suspected contributors to marrow DNA injury.

16. Prior chronic myeloid or myeloproliferative disease that shifts toward dysplasia and blasts.

17. Chronic viral infections (rare; proposed mechanism is marrow stress and DNA injury).

18. Autoimmune disease requiring prolonged immunosuppressants – long-term marrow stress and mutagenic exposures raise risk.

19. Obesity and metabolic stress – associated with oxidative stress and clonal evolution (supportive risk data are emerging).

20. Unknown/idiopathic factors – in many patients no single exposure is found, yet the typical genetic patterns of AML-MR still develop.

(Several of the above causes contribute by first causing MDS biology—the recognized “staging ground” for AML-MR. Modern guidelines emphasize history plus cytogenetic/molecular evidence when deciding AML-MR.) College of American Pathologists

Symptoms

1. Tiredness and weakness – due to anemia (low red cells).

2. Shortness of breath on exertion – another sign of anemia.

3. Pale skin – reduced hemoglobin makes the skin look pale.

4. Easy bruising – platelets are often low or do not work well.

5. Bleeding (gums, nose, heavier periods) – because of thrombocytopenia and fragile blood vessels.

6. Frequent infections – white cells are abnormal or too few.

7. Fever – can reflect infection or cancer-related inflammation.

8. Bone or joint pain – crowded marrow can ache.

9. Night sweats – a “B-symptom” of active blood cancers.

10. Unintended weight loss – reflects high metabolic activity of the disease.

11. Fullness in the left upper abdomen – enlarged spleen from marrow stress and abnormal blood cell breakdown.

12. Swollen gums or gum overgrowth – more common with monocytic leukemia cells.

13. Skin rashes or purple spots (petechiae) – bleeding under the skin from low platelets.

14. Headache, dizziness, or confusion – severe anemia or very high white counts can reduce blood flow (“leukostasis”).

15. Enlarged lymph nodes (less common) – can occur with tissue “myeloid sarcoma.”

Diagnostic tests

A) Physical Examination

1. General exam and vital signs
   The clinician checks temperature, heart rate, breathing rate, and blood pressure. Fever suggests infection risk; fast heart rate or low blood pressure may reflect anemia or sepsis. A full general exam sets the urgency of care.

2. Skin and mucosa check
   Looking for pallor, bruises, petechiae, and gum bleeding gives quick clues about anemia and low platelets. Mouth inspection can also show gum overgrowth from leukemic infiltration.

3. Lymph node exam
   The doctor gently feels neck, armpits, and groin. Large, firm nodes are not typical but can occur; when present, they may raise the possibility of tissue disease (myeloid sarcoma) requiring imaging or biopsy.

4. Abdominal exam (liver and spleen)
   An enlarged spleen or liver suggests high cell turnover and blood cell trapping—common in myeloid diseases. The spleen tip can be felt under the left rib cage in many cases.

5. Neurologic screening
   A quick check for headaches, confusion, weakness, or vision changes helps catch leukostasis or bleeding. If abnormal, doctors may escalate to brain imaging.

B) Manual (microscopy/bedside) Tests

6. Peripheral blood smear (manual slide review)
   A technologist or pathologist looks at a stained blood smear under a microscope. Seeing blasts, Auer rods, dysplastic neutrophils, or giant platelets supports the suspicion of AML-MR and guides urgent work-up.

7. Manual differential count
   Counting 100–200 cells by hand estimates the percentage of blasts and other white cell types. This manual count cross-checks automated machines, especially when cells look abnormal.

8. Bone marrow aspirate smear (manual morphology)
   Aspirated marrow is spread on glass slides and examined for blasts and dysplasia in red cell, white cell, and platelet lines. In AML-MR, ≥20% blasts (for this category) plus dysplasia are typical, but dysplasia alone is not enough to make the AML-MR label without the genetic/history criteria. College of American Pathologists

9. Cytochemical stains (e.g., MPO, Sudan Black B, nonspecific esterase)
   These older but still useful stains help confirm myeloid lineage and monocytic features when flow cytometry is limited or equivocal.

10. Manual reticulocyte count
    Counting young red cells assesses marrow response to anemia. In AML-MR, reticulocytes are often low because normal red-cell production is suppressed.

C) Laboratory & Pathological Tests

11. Complete blood count (CBC) with indices
    Shows anemia, abnormal white counts (high or low), and low platelets. Mean cell volume and other indices often reflect underlying dysplasia.

12. Comprehensive metabolic panel, uric acid, LDH, phosphorus, potassium
    These basic chemistries check organ function and look for tumor lysis risk (high uric acid, high potassium, high phosphate) that can occur at presentation.

13. Coagulation panel (PT/INR, aPTT, fibrinogen, D-dimer)
    Screens for bleeding risk and disseminated intravascular coagulation, which sometimes accompanies aggressive leukemia.

14. Bone marrow core biopsy (histology)
    A trephine core shows cellularity, fibrosis, and architecture. It supports the blast estimate and the degree of dysplasia and provides material for immunohistochemistry and additional studies.

15. Flow cytometry (immunophenotyping)
    Labels the blasts with antibodies to define myeloid lineage and exclude acute lymphoblastic leukemia or mixed-phenotype disease. It also provides a leukemia “signature” to follow as measurable residual disease (MRD) during treatment.

16. Conventional karyotyping (cytogenetics)
    Looks at all chromosomes in dividing cells. MDS-type abnormalities and complex karyotype strongly support AML-MR. This test also detects other AML-defining fusions that change management. Nature

17. FISH (fluorescence in situ hybridization) panels
    Targets specific chromosome regions when karyotyping is slow or the abnormality is subtle (“cryptic”). Helpful for confirming MDS-related cytogenetic changes. College of American Pathologists

18. Next-generation sequencing (NGS) for myeloid genes
    A targeted panel checks for the eight “MR genes” (SRSF2, SF3B1, U2AF1, ZRSR2, ASXL1, EZH2, BCOR, STAG2). Finding any of these supports the AML-MR category in WHO 2022. Nature

19. PCR/NGS for other AML-defining abnormalities
    Tests for NPM1, CEBPA, KMT2A, NUP98, MECOM, BCR::ABL1, etc., because these can alter both the diagnosis family and treatment decisions. Modern guidelines emphasize a genetics-first approach. Nature

20. MRD assays after treatment (flow or molecular)
    After therapy starts, sensitive tests measure tiny levels of remaining leukemia. MRD status helps predict relapse risk and informs transplant timing. College of American Pathologists

D) Electrodiagnostic Tests

21. 12-lead electrocardiogram (ECG)
    Leukemia itself does not live on the ECG, but baseline ECG is essential before anthracyclines or QT-prolonging drugs, and it helps manage electrolyte shifts from tumor lysis. It also screens for silent heart strain in very anemic patients.

22. EEG (when neurologic symptoms suggest seizures or encephalopathy)
    Rarely needed, but in patients with confusion or suspected seizure—especially with very high white counts or CNS bleeding—EEG helps assess brain function while imaging is arranged.

E) Imaging Tests

23. Chest X-ray (CXR)
    Quick screen for pneumonia in neutropenic or febrile patients; also shows fluid overload or heart enlargement that may affect chemotherapy planning.

24. CT or MRI (site-directed)
    Head CT/MRI for neurologic symptoms; abdomen/pelvis for organ size or pain; soft-tissue imaging when a myeloid sarcoma (chloroma) is suspected. Imaging guides biopsy and staging.

25. Echocardiogram
    An ultrasound of the heart (non-invasive imaging) to measure ejection fraction before starting anthracyclines. This helps balance leukemia urgency with cardiac safety.

   Dose: 50–150 mg/day adjusted.
   Function: Stimulates platelet production via TPO receptor.
   Caution: AML contexts are limited/individualized because of theoretical blast stimulation—used only when a specialist deems appropriate.

Procedures / “Surgeries

1. Allogeneic Hematopoietic Stem-Cell Transplant (HSCT)
   Procedure: High-dose chemo (sometimes plus radiation), then infusion of donor stem cells.
   Why: Offers the best chance of long-term control/cure for fit patients with high-risk AML-MR by replacing diseased marrow and adding a donor immune attack against leukemia (graft-versus-leukemia).

2. Central Venous Catheter / Port Placement
   Procedure: Minor surgery to insert a tunneled line or port.
   Why: Safe delivery of chemo, transfusions, and blood draws over months.

3. Leukapheresis
   Procedure: Machine removes excess white cells from the blood.
   Why: Rapid temporary lowering of dangerously high blast counts to reduce stroke/lung risks before chemo works.

4. Lumbar Puncture with Intrathecal Chemotherapy
   Procedure: Needle into lower back to sample or give medicine into spinal fluid.
   Why: Prevent or treat leukemia spread to the brain/spinal fluid in selected cases.

5. Splenectomy (rare)
   Procedure: Surgical removal of an enlarged, overactive spleen.
   Why: Considered only in special situations (e.g., painful massive spleen or severe blood-cell destruction not controlled otherwise).

Prevention & Safety Tips

1. No smoking; avoid benzene/solvent exposures (workplace safety).

2. Vaccinations for family/household (flu, COVID, etc.) at safe times per team advice.

3. Hand hygiene and mask in crowds/clinics during neutropenia.

4. Food safety: well-cooked meats/eggs; avoid unpasteurized dairy/raw sprouts/sushi.

5. Prompt fever plan: thermometer at home; call if ≥38.0°C (100.4°F).

6. Skin care: moisturize, protect from cuts; soft toothbrush; electric razor.

7. Oral care: bland rinses, dental checks before intensive therapy.

8. Sun safety during photosensitizing meds; protect the port site.

9. Medication reconciliation at every visit—avoid interactions.

10. Exercise & rest balance—small daily movement plus naps.

When to See a Doctor Urgently

• Fever ≥38.0°C (100.4°F), chills, or feeling suddenly unwell

• Bleeding you cannot stop, black stools, blood in urine, severe nosebleed

• Shortness of breath, chest pain, confusion, severe headache

• New rash, mouth sores preventing drinking, or fast worsening weakness

• Any sudden swelling/pain in legs (possible clot) or IV site redness

• Yellow eyes/skin, very dark urine, or severe abdominal pain

What to Eat and What to Avoid

1. Eat: well-cooked proteins (egg, chicken, fish, tofu, legumes).

2. Eat: soft, high-calorie snacks (yogurt*, puddings, bananas, shakes). *Pasteurized only.

3. Eat: peeled/cooked fruits and vegetables; wash thoroughly.

4. Eat: small, frequent meals; keep an oral rehydration drink handy.

5. Eat: iron- and folate-rich foods as tolerated (beans, greens)—but do not start supplements without labs.

6. Avoid: raw/undercooked meats, sushi, runny eggs, unpasteurized milk/cheese.

7. Avoid: salad bars/buffets during neutropenia.

8. Avoid: grapefruit, Seville oranges, and St. John’s wort with many AML meds (drug interactions).

9. Avoid: alcohol excess; ask before any herbal products.

10. Food safety first: clean hands, separate cutting boards, chill leftovers quickly.

Frequently Asked Questions

1. Is AML-MR different from “regular” AML?
   Yes. It shows marrow “dysplasia,” certain chromosome changes, or specific “MR” gene mutations linked to prior MDS-type biology and often higher risk. PMCASH Publications

2. What genes does AML-MR often have?
   Common MR genes include ASXL1, BCOR, EZH2, STAG2, SF3B1, SRSF2, U2AF1, ZRSR2; some systems also consider RUNX1. PMCASH Publications

3. Why is CPX-351 often mentioned for AML-MR?
   Because it’s FDA-approved specifically for AML with myelodysplasia-related changes and therapy-related AML. FDA Access DataU.S. Food and Drug Administration

4. If I’m older or not fit for intensive chemo, do I still have options?
   Yes—azacitidine or decitabine plus venetoclax and other lower-intensity plans can be effective. PMC

5. Is transplant the only cure?
   Transplant offers the best chance of long-term control for many with high-risk AML-MR, but some patients achieve durable remissions without it. Your team weighs risks and benefits.

6. How are infections prevented during low counts?
   Vaccines (at the right time), protective antibiotics/antifungals when indicated, masks, hand hygiene, and food safety.

7. What is “differentiation syndrome”?
   A sudden inflammatory reaction that can happen with IDH inhibitors (and other agents). It causes fever, breathing trouble, and swelling; doctors treat it urgently with steroids.

8. Can I take vitamins or herbs?
   Only with your team’s approval. Some supplements interact with AML medicines (liver enzymes/QT/bleeding).

9. Why are transfusions common?
   AML and treatment suppress marrow, so you may need red cells for energy and platelets to prevent bleeding.

10. What is tumor lysis syndrome?
    When many leukemia cells die quickly, releasing contents that can harm kidneys and heart. Doctors prevent it with hydration and allopurinol or rasburicase.

11. Will I lose my hair?
    Many intensive regimens cause hair loss. It usually regrows after therapy ends.

12. Can I work during treatment?
    Some do part-time remote work during lower-intensity cycles; many need leave during induction. Energy and infection risk guide this.

13. How long is treatment?
    Induction is weeks; consolidation or maintenance can take months. Transplant adds preparation and recovery time.

14. What if my leukemia has FLT3 or IDH mutations too?
    Targeted drugs like midostaurin, gilteritinib, ivosidenib, or enasidenib may be added depending on setting.

15. What matters most day-to-day?
    Report fevers immediately, follow your medication list, practice food and hand hygiene, and save energy for what matters most.
