Paediatric Hematological Malignancies Management (ALL, AML, MDS, Lymphoma)
Paediatric hematological malignancies refer to cancers that affect the blood, bone marrow, and lymphatic system in children. Common conditions include Acute Lymphoblastic Leukemia (ALL), Acute Myeloid Leukemia (AML), Myelodysplastic Syndromes (MDS), and various types of Lymphoma. Management of these diseases involves a multidisciplinary approach, integrating cutting-edge therapies, supportive care, and long-term monitoring to optimize outcomes.
Key Components of Management
Accurate Diagnosis and Risk Stratification:
- Advanced Diagnostic Techniques:
Blood tests, bone marrow aspiration, biopsy, and imaging studies.
Genetic and molecular testing to classify the malignancy and predict treatment response. - Risk Stratification: Categorizes patients into standard or high-risk groups to tailor treatment intensity.
Chemotherapy:
- Forms the backbone of treatment for most pediatric hematological cancers.
- Administered in phases (induction, consolidation, maintenance) to achieve and sustain remission.
- Personalized protocols are used based on the type and risk group of the malignancy.
Targeted Therapy:
- Uses drugs that specifically target cancer cells, sparing normal cells.
- Examples include tyrosine kinase inhibitors (e.g., Imatinib for Philadelphia chromosome-positive ALL).
Immunotherapy:
- Enhances the child’s immune system to combat cancer.
- Includes monoclonal antibodies, CAR-T cell therapy, and immune checkpoint inhibitors.
Bone Marrow Transplantation (Hematopoietic Stem Cell Transplant - HSCT):
- Recommended for high-risk or relapsed cases of leukemia, lymphoma, or MDS.
- Restores healthy blood cell production after intensive chemotherapy or radiation.
Supportive Care:
Addresses complications and improves quality of life:
- Blood and platelet transfusions for anemia and thrombocytopenia.
- Management of infections with antimicrobial therapy.
- Nutritional and psychological support for overall well-being.
Radiation Therapy:
- Used selectively for certain lymphomas or as part of preparative regimens for HSCT.
Long-term Monitoring and Survivorship Care:
- Regular follow-ups to detect late effects, monitor growth, and address developmental needs.
- Survivorship programs focus on transitioning children to a healthy adulthood.
Key Features of Management by Condition
- ALL (Acute Lymphoblastic Leukemia): Most common pediatric leukemia; high cure rates with chemotherapy and targeted therapies.
- AML (Acute Myeloid Leukemia): Aggressive chemotherapy and HSCT for high-risk or relapsed cases.
- MDS (Myelodysplastic Syndromes): HSCT is the only curative option for most cases, often combined with supportive care.
- Lymphoma (Hodgkin’s and Non-Hodgkin’s): Chemotherapy with or without radiation; targeted therapies for refractory cases.
Goals of Management
- Achieve complete remission.
- Minimize treatment-related toxicity.
- Address psychosocial and developmental needs.
- Provide holistic care to ensure long-term survival and quality of life.
