Study Notes
Risk Groups in MDS and AML
- Low-risk groups: IPSS low, IPSS intermediate-1, IPSS-R very low, IPSS-R low.
- High-risk groups: IPSS intermediate-2, IPSS high, IPSS-R intermediate, IPSS-R high, IPSS-R very high.
Treatment Goals for MDS
- Alter natural disease progression.
- Decrease reliance on red blood cell transfusions.
- Enhance quality of life.
Comorbidities in MDS
- About 50% of newly diagnosed MDS patients have one or more comorbidities, complicating treatment options.
- Evaluating comorbid conditions is crucial for effective management.
Curative Options
- Only allogeneic hematopoietic stem cell transplantation offers a potential cure for MDS.
Recommended Therapies for MDS
- Lower-risk patients benefit from:
- Hematopoietic growth factors.
- DNA hypomethylating agents.
- Immunosuppressive therapies.
- Higher-risk patients may benefit from:
- Intensive chemotherapy.
- Allogeneic hematopoietic stem cell transplantation.
Management of Lower-Risk MDS
- Treatment depends on transfusion independence; typically monitored until transfusion dependence arises.
- Transfusion support is provided with packed RBCs and platelets as necessary.
Diagnostic Criteria for AML
- Diagnosis requires ≥20% peripheral blasts or bone marrow biopsy findings consistent with AML.
- Karyotype abnormalities can also indicate AML regardless of blast percentages, including specific mutations like t(8;21) and inversion(16).
Prognostic Factors for AML
- Patient-specific factors affecting prognosis:
- Age ≥60 is linked to reduced overall survival due to therapy tolerability issues.
- Comorbidities and performance status impact treatment outcomes.
- AML biology-specific factors:
- Karyotype is the strongest prognostic factor for induction therapy responses.
- Distinct genetic abnormalities influence overall survival and treatment sensitivity.
Complete Remission (CR) Criteria for AML
- Absolute neutrophil count > 1 X 10^9.
- Platelet count > 100 X 10^9.
- Independence from transfusions.
- Bone marrow blast percentage < 5%.
- No Auer rod presence and absence of extramedullary disease.
Remission Induction Therapy Principles
- Low-intensity induction therapy is suitable for older or unfit patients.
- Focus on achieving normal hematopoiesis and improving quality of life rather than requiring complete remission.
- Transfusion needs may decrease without achieving complete remission.
Intensive Therapy for AML
- Younger patients often receive intensive remission induction therapy.
- The overall response rate (ORR) can reach 43%, noting that decitabine may improve complete response rates (CR rates of 17.8% vs. 7.8%).
