Acute Myelodysplasia with Myelofibrosis (APMF)

Acute myelodysplasia with myelofibrosis (APMF) is a sudden and severe bone-marrow disease. The bone marrow, which normally makes red cells, white cells, and platelets, becomes packed with very immature cells called blasts. At the same time, thick scar-like fibers grow through the marrow (myelofibrosis). Because of this, the marrow cannot release enough healthy cells. People develop anemia (low red cells), infections (low white cells), and bleeding or bruising (low platelets). The blast count is usually 20% or higher in the marrow or blood, which places it under acute myeloid leukemia in modern systems. It is rare, fast-moving, and needs urgent specialist care. SEEROrphaCollege of American Pathologists

This is a rare, fast-growing blood and bone-marrow cancer. All three blood-making cell lines (red cells, white cells, platelets) start to grow abnormally and immature “blast” cells go up. At the same time, scar tissue forms inside the bone marrow (called myelofibrosis). Because of the scarring, the marrow cannot make healthy blood cells, so people become anemic, prone to infections, and bruise or bleed easily. In medical books this disease is called acute panmyelosis with myelofibrosis (APMF). Older and alternate names include “acute myelodysplasia with myelofibrosis,” “malignant (acute) myelofibrosis,” and “acute myelosclerosis.” SEER

Another names

This disease has appeared in the literature under many labels. The most common are: Acute panmyelosis with myelofibrosis (APMF), acute (malignant) myelofibrosis, acute (malignant) myelosclerosis, acute myelodysplasia with myelofibrosis, acute panmyelosis, and occasionally malignant myelofibrosis. Earlier reports also used acute myelosclerosis. These names reflect the same clinicopathologic picture: an acute marrow-wide proliferation of immature cells (blasts) with marked marrow fibrosis, rapid onset cytopenias, and high short-term risk. Today, APMF is generally categorized within acute myeloid leukemia rather than myelodysplastic syndromes. Genetic Rare Diseases CenterSEERASH Publications

Types

There is no universally accepted “subtyping” for this disease in current classifications. However, clinicians often describe practical patterns that help with reasoning and management:

1) De novo APMF. This pattern appears without a known prior bone-marrow disease. It presents abruptly with pancytopenia, very fibrotic marrow, and high blasts. It behaves aggressively and is treated as acute leukemia. ASH Publications

2) Secondary/therapy-related APMF-like presentations. Similar clinicopathologic pictures can arise after prior chemotherapy, radiation, or toxic exposures that damage the marrow. The biology and outlook are often worse. PubMed

3) Overlap with MDS with fibrosis (MDS-F). Some people show myelodysplastic changes with significant marrow fibrosis and then evolve quickly into an acute, APMF-like phase. MDS with fibrosis carries a poorer prognosis than MDS without fibrosis, so early recognition matters. PMC+1

4) Overlap with acute megakaryoblastic leukemia (AMKL). APMF and AMKL may share features (marked fibrosis, megakaryocytic markers), and careful pathology is needed to separate them. Nature

Note: In WHO/ICC updates, AML with myelodysplasia-related changes (AML-MRC) is defined differently (by clinical history, dysplasia, or specific cytogenetics) and is not the same as APMF, although blasts and dysplasia can coexist. NCBIASH Publications

Causes

Because APMF is rare, “causes” are best framed as associations seen in case series and related marrow disorders. Not every person has a clear trigger.

1. Prior myelodysplastic syndrome (MDS). Fibrotic MDS can transform abruptly to an APMF-like acute phase. PMC

2. Previous chemotherapy (alkylators, topoisomerase II inhibitors) for another cancer. NCBI

3. Radiation exposure (therapeutic or accidental). NCBI

4. Benzene and other marrow toxins in occupational settings. PubMed

5. Complex cytogenetic abnormalities seen in AML/MDS biology. NCBI

6. TP53 mutation (common in therapy-related/complex karyotype AML/MDS; often aggressive). HealthTree

7. RUNX1-pathway alterations (seen across myeloid neoplasia with dysplasia). NCBI

8. Ageing marrow (risk of myeloid neoplasms rises with age). ASH Publications

9. Prior myeloproliferative neoplasm with fibrosis (rare progression patterns). Nature

10. Immune/autoimmune marrow injury leading to hypocellular precursors that later transform. PMC

11. Viral triggers suspected in case reports (association rather than proof). PubMed

12. Cigarette smoke and solvent exposure (broad AML/MDS risk data). ASH Publications

13. Inherited DNA repair defects (predispose to therapy-related AML-like biology). ASH Publications

Symptoms

1. Severe tiredness. Low red cells starve the body of oxygen, so everyday tasks exhaust the person.

2. Shortness of breath on exertion. Anemia makes the heart and lungs work harder to deliver oxygen.

3. Pale skin or conjunctiva. Less hemoglobin means visible paleness.

4. Fast heartbeat and palpitations. The heart beats faster to compensate for anemia. (ECG often shows sinus tachycardia.)

5. Frequent infections. Low neutrophils weaken defenses; fevers are common.

6. Fever without a clear source. Can reflect infection or cytokines from leukemia.

7. Easy bruising. Low platelets make small impacts leave large marks.

8. Bleeding gums or nosebleeds. Platelet shortage and fragile mucosa cause bleeding.

9. Prolonged bleeding from cuts. Clotting is slower when platelets are very low.

10. Petechiae (pinpoint skin spots). Tiny bleeds under the skin signal thrombocytopenia.

11. Bone pain or sternal tenderness. Marrow expansion and fibrosis can ache.

12. Back pain. Reported in case descriptions and may reflect marrow changes. PubMed

13. Night sweats. A sign of high cell turnover and inflammation.

14. Unintentional weight loss. Catabolic state and reduced appetite.

15. Abdominal fullness (sometimes). Spleen can enlarge, though organomegaly may be absent in APMF. PubMed

Diagnostic tests

A) Physical examination (bedside observations)

1. General appearance and vital signs. Fever, rapid pulse, and rapid breathing suggest infection and anemia stress.

2. Skin inspection. Look for pallor, bruises, and petechiae that point to low counts.

3. Mouth/nose exam. Bleeding gums, mucosal petechiae, or ulcers hint at thrombocytopenia and neutropenia.

4. Lymph node check. Large nodes are less typical in APMF but must be noted to exclude other causes.

5. Abdominal palpation/percussion. Assess spleen and liver size; enlargement changes risk and differential.

6. Chest exam. Crackles or signs of pneumonia are important when neutropenic fever is present.

7. Sternal tenderness. Local tenderness may reflect intense marrow activity and fibrosis.

Why this matters: Physical signs are quick clues that guide urgent supportive care (antibiotics, transfusions) while lab confirmation proceeds.

B) “Manual” clinical tests and procedures (simple, non-lab tools clinicians use)

8. Orthostatic blood pressure/heart rate. A drop in pressure or big pulse rise suggests volume depletion or severe anemia.

9. Capillary refill time. Slow refill (>2 sec) supports poor perfusion from anemia or sepsis.

10. Bedside bleeding time or platelet function screening (where available). Helps explain mucosal bleeding while awaiting labs.

11. Stool occult blood test. Finds hidden GI bleeding that worsens anemia.

12. Bedside ultrasound (POCUS) for spleen size and free fluid. Rapid, radiation-free triage when unstable.

Why this matters: These simple checks flag immediate risks and help prioritize transfusion, antibiotics, and imaging.

C) Laboratory & pathological tests (the diagnostic core)

13. Complete blood count (CBC) with differential and reticulocyte count. Shows pancytopenia with low reticulocytes (marrow failure) and circulating blasts.

14. Peripheral blood smear review. A pathologist checks for blasts, dysplastic cells, and tear-drop forms; these hint at fibrosis and acute leukemia.

15. Bone marrow aspiration and trephine biopsy. Often a “dry tap” occurs because of fibrosis; the core biopsy shows panmyelosis with ≥20% blasts and dense reticulin/collagen fibrosis. Special stains (silver reticulin, trichrome) grade fibrosis. SEER

16. Flow cytometry immunophenotyping. Confirms the myeloid nature of blasts and compares with megakaryoblastic patterns when needed. PubMed

17. Cytogenetics (karyotype) and FISH. Detects myelodysplasia-related or complex changes that shape prognosis. NCBI

18. Molecular testing (NGS panel). Looks for TP53, RUNX1, and other mutations that signal aggressive biology. HealthTree

19. Coagulation profile (PT/INR, aPTT, fibrinogen, D-dimer). Screens for DIC-like changes that sometimes occur in acute leukemias.

20. Tumor lysis risk labs (uric acid, LDH, potassium, phosphate, creatinine). High cell turnover raises these; guides prevention and treatment.

21. Exclusion labs when the picture is unclear: B12/folate (to exclude megaloblastic anemia), hemolysis markers, viral serologies if clinically indicated.

22. Pathology review to distinguish AMKL, MDS-F, and APMF. Multidisciplinary review is key because APMF and AMKL can overlap, but correct labeling changes therapy approach. Nature

Why this matters: The biopsy with fibrosis grading plus blast quantification is decisive, while genetics and mutations refine prognosis and trial eligibility.

D) Electrodiagnostic and monitoring tests

23. 12-lead ECG. Checks for anemia-related tachycardia, ischemia in severe anemia, electrolyte-related arrhythmias during treatment.

24. Continuous cardiac monitoring or Holter in unstable patients. Tachyarrhythmias and QT issues may appear during therapy.

25. Pulse oximetry. Detects hypoxemia during infection or transfusion reactions.

26. Electrolyte-related conduction assessment (ECG trend). Helpful when giving tumor-lysis therapy (e.g., potassium shifts).

27. EEG (rarely) if unexplained seizures or encephalopathy develop during severe illness.

Why this matters: These tools protect the heart and brain during high-risk periods of anemia, infection, and intensive treatment.

E) Imaging tests

28. Ultrasound abdomen. Measures spleen and liver size, checks for portal hypertension or infarcts when pain occurs.

29. Chest X-ray. Screens for pneumonia in neutropenic fever and for line-related complications.

30. CT scan (targeted). Looks for internal bleeding, deep infection, or organ infarcts when symptoms point that way.

31. MRI of spine or pelvis if severe focal bone or back pain raises concern for other causes. PubMed

32. Whole-body imaging when indicated (e.g., CT/PET in atypical cases) to investigate fevers or extramedullary disease.

Why this matters: Imaging supports complication management and helps rule in/out alternative diagnoses; it does not replace marrow testing.

Non-pharmacological treatments

Dietary “molecular and supportive

(Supportive only—always clear with your oncology team. Avoid unapproved supplements during neutropenia or with interacting drugs.)

1. Protein repletion (whey, eggs, fish, legumes) – Dose: include high-quality protein at each meal. Function/Mechanism: Supplies amino acids to rebuild muscle and immune proteins; helps wound healing and enzyme systems. Note: Choose pasteurized/fully cooked sources when counts are low.

2. Vitamin D (correct deficiency) – Dose: per blood level and clinician order. Function: Supports bone, muscle, and immune regulation. Mechanism: Nuclear receptor effects that modulate innate/adaptive responses. Caution: Avoid high doses without labs.

3. Omega-3 fatty acids from food (oily fish, flax) – Dose: 2 fish servings/week unless advised otherwise. Function: Anti-inflammatory signal balance. Mechanism: Competes with arachidonic acid pathways; may ease cachexia-related inflammation. Caution: Watch bleeding risk when platelets are low—food sources preferred.

4. Soluble fiber (oats, bananas, cooked veggies) – Dose: add gradually. Function: Gut comfort and microbiome support. Mechanism: Fermentation to short-chain fatty acids that nourish colon lining. Caution: Choose well-washed, well-cooked forms during neutropenia.

5. Folate/B12 repletion if deficient – Dose: only with lab-confirmed deficiency. Function: DNA/RNA synthesis and red-cell health. Mechanism: Cofactors for nucleotide pathways. Caution: Never self-supplement high doses without team guidance in AML.

6. Zinc (from diet or supervised supplement) – Function: Wound healing and enzyme function. Mechanism: Cofactor in immune signaling and protein structure. Caution: Excess may upset copper balance; get advice first.

7. Electrolyte-rich fluids – Function: Support kidneys during tumor-lysis risk periods and prevent dehydration. Mechanism: Maintains perfusion and drug clearance. Caution: Tailor to heart/kidney status.

8. Antiemetic-friendly small meals – Function: Keep calories in during nausea. Mechanism: Smaller gastric load reduces nausea triggers; bland choices are easier to tolerate. Benefit: Weight maintenance.

9. Iron intake moderation if transfusion-dependent – Function: Avoid extra iron burden. Mechanism: Limits absorption that can add to transfusional iron; follow doctor on chelation if needed. Caution: Never restrict iron if you are iron-deficient unless told.

10. Food-safety protocol (“neutropenic precautions”) – Function: Lower infection risk. Mechanism: Avoids raw/undercooked foods, unpasteurized items, salad bars, and unwashed produce during profound neutropenia. Benefit: Fewer GI infections. (Evidence and practices vary by center; follow your team’s policy.)

---

Immunity-booster / regenerative / stem-cell–related

(These are prescription medical therapies, not over-the-counter boosters.)

1. G-CSF (filgrastim) – Dose: short courses post-chemo per protocol. Function: Help neutrophils recover. Mechanism: Stimulates marrow production and release. Note: Used selectively; may not be appropriate in all AML phases.

2. GM-CSF (sargramostim) – Dose: specialist-directed. Function: Broader myeloid stimulation. Mechanism: Acts on progenitors and antigen-presenting cells. Note: Also selective due to side-effects.

3. IVIG (intravenous immunoglobulin) – Dose: case-by-case for recurrent serious infections with low immunoglobulins. Function: Passive antibodies. Mechanism: Supplements humoral immunity. Caution: Infusion reactions, headache; limited indications.

4. Erythropoiesis-stimulating agents (epoetin alfa/darbepoetin) – Dose: weight- and Hb-guided. Function: Red-cell regeneration to reduce transfusions. Mechanism: Stimulates erythroid precursors. Caution: Thrombosis risk, not for all patients.

5. Palifermin (keratinocyte growth factor) in transplant settings – Dose: per transplant protocol. Function: Protect mucosal lining. Mechanism: Stimulates epithelial repair. Benefit: Less severe mouth/throat mucositis after high-dose therapy.

6. Allogeneic hematopoietic stem-cell transplantation (HSCT) – Not a drug but the core regenerative therapy. Function: Replace diseased marrow with donor stem cells. Mechanism: High-dose conditioning wipes out cancer cells; donor cells engraft and rebuild blood formation; graft-versus-leukemia effect adds anti-cancer power. Note: Only for selected patients with careful risk–benefit review; may offer the best chance for durable cure. ASTCT Journal

---

Procedures / Surgeries

1. Allogeneic HSCT – See above. Why: Potential cure/durable control. Procedure: Conditioning chemo (± radiation), infusion of donor stem cells, protective care in neutropenia. Risks: Infections, graft-versus-host disease, organ toxicities. ASTCT Journal

2. Central venous catheter or port placement – Why: Reliable access for chemo, transfusions, antibiotics, and blood draws. Procedure: Minor surgical insertion under sterile conditions. Risks: Infection, clot, line malfunction.

3. Leukapheresis (select cases) – Why: Rapidly lower very high white counts causing leukostasis risk before chemo can act. Procedure: Machine removes blasts from blood temporarily. Risks: Line issues, electrolyte shifts; short-term bridge.

4. Splenic irradiation (palliative, if symptomatic splenomegaly occurs) – Why: Ease pain or fullness when enlarged spleen causes discomfort or low counts from sequestration. Procedure: Local radiation in small fractions. Risks: Worsening cytopenias; used cautiously.

5. Splenectomy (rare, carefully selected) – Why: Severe symptoms or refractory low platelets due to spleen sequestration despite other measures. Procedure: Surgical removal of spleen. Risks: Surgical risks and lifelong higher infection risk; vaccinations required.

Preventions and safety habits

1. Report fever ≥38.0 °C immediately (single reading or repeated 37.8–38).

2. Hand hygiene, mask in crowds, and avoid sick contacts during low counts.

3. Food safety: no raw/undercooked meats, unwashed produce, or unpasteurized dairy during neutropenia.

4. Medication checkups: avoid NSAIDs and blood-thinners unless approved when platelets are low; avoid supplement/herb interactions (e.g., grapefruit interactions with some oral agents). College of American Pathologists

5. Oral care: soft brush, alcohol-free rinse; manage mouth sores early.

6. Skin care: moisturize, treat cuts fast, avoid foot injuries.

7. Sun and heat: protect during photosensitizing drugs; hydrate well.

8. Vaccinations: stay up to date per oncology guidance (inactivated only; timing matters).

9. Avoid benzene/solvents and tobacco smoke; use workplace PPE.

10. Safe travel plan: carry summary, nearby hospital list, and enough meds.

What to eat and what to avoid

1. Eat: fully cooked proteins (fish, chicken, eggs), beans, lentils—avoid: raw/undercooked animal products during neutropenia.

2. Eat: soft fruits you can peel or wash very well—avoid: salad bars/unwashed produce when counts are very low.

3. Eat: whole grains and cooked vegetables—avoid: unpasteurized juices/dairy.

4. Eat: small, frequent meals to fight nausea—avoid: large greasy meals that worsen nausea.

5. Drink: plenty of water or oral rehydration—avoid: alcohol (raises bleeding/infection risk) and energy drinks.

6. Use: gentle seasonings and lemon/ginger for flavor—avoid: very spicy foods if mouth sores.

7. Choose: food sources of omega-3s (well-cooked fish)—avoid: fish high in mercury or raw sushi in neutropenia.

8. Include: yogurt only if pasteurized and your team allows—avoid: “probiotic” products without approval.

9. If transfusion-dependent: get iron advice—avoid: high-iron supplements unless prescribed.

10. Check labels for interactions (e.g., grapefruit)—avoid herbs/supplements unless cleared with your team. College of American Pathologists

Frequently Asked Questions

1. Is APMF the same as myelofibrosis?
   No. APMF is an acute leukemia with marrow scarring. Primary myelofibrosis is a chronic myeloproliferative neoplasm. SEER

2. Why is it sometimes called “acute myelodysplasia with myelofibrosis”?
   That is an older/alternate name; today it is grouped with AML as acute panmyelosis with myelofibrosis. SEER

3. What causes it?
   The exact trigger is not always known. It may arise “de novo” or after prior marrow disease or exposures. Genes and signals that drive scarring and blast growth are involved. PubMed

4. How rare is it?
   Very rare—a tiny fraction of AML cases. Lippincott Journals

5. What are the main symptoms?
   Fatigue/shortness of breath (anemia), infections (low neutrophils), bruising/bleeding (low platelets), and sometimes bone pain or fever.

6. How is it diagnosed?
   Blood tests, bone-marrow biopsy with special stains for fibrosis, blast counts, flow cytometry, chromosome and gene tests. The combination of blasts ≥20% and fibrosis supports the diagnosis. SEER

7. How is it different from acute megakaryoblastic leukemia (AMKL)?
   They can look similar, but APMF shows pan-myeloid involvement with fibrosis; criteria differ from AMKL, though there is overlap. Experts review the biopsy carefully. Nature

8. Is there a standard treatment?
   Because it is so rare, there is no single standard proven best for all. Doctors adapt AML regimens and consider early HSCT if feasible. ASTCT JournalLippincott Journals

9. Can it be cured?
   Some patients can achieve long remissions, especially with allogeneic transplant. Outcomes vary with age, fitness, genetics, and response. ASTCT Journal

10. Will I need transfusions?
    Often yes, for anemia or low platelets, especially during treatment.

11. Are targeted drugs possible?
    Yes, if your leukemia has certain mutations (e.g., FLT3, IDH1/2), targeted pills may be added. Testing guides this. College of American Pathologists

12. Is my spleen always big?
    Not always. APMF can have minimal splenomegaly, unlike classic myelofibrosis. Lippincott Journals

13. What about exercise?
    Gentle, planned activity is helpful and safe when matched to your blood counts and symptoms (see physiotherapy list). Always ask your team first.

14. Should I change my diet?
    Yes—focus on safe food handling, enough protein and fluids, and avoid high-risk raw foods during neutropenia. See the food list above.

15. Where can I read the classification details?
    Modern AML classifications (WHO/ICC) include APMF under AML categories; your team can explain how this applies to you. ASH PublicationsPMC
