Leukemia
Known Symptoms
- Bone marrow failure effects: Anemia (fatigue, pallor, shortness of breath).
Thrombocytopenia (bruising, petechiae, bleeding).
Neutropenia (fever, recurrent infections). - Organ infiltration: Hepatosplenomegaly, lymphadenopathy. Bone/joint pain, CNS involvement (headache, cranial nerve palsies).
- Constitutional symptoms: Weight loss, night sweats.
- Red flags: Unexplained fevers with cytopenias, spontaneous bleeding, or rapidly enlarging masses.
Known Causes
- Genetic mutations (e.g., BCR-ABL in CML, FLT3 in AML).
- Environmental exposures (ionizing radiation, benzene, chemotherapy agents).
- Genetic syndromes (e.g., Down syndrome, Fanconi anemia).
- Viral infections (e.g., HTLV-1 associated with adult T-cell leukemia).
- Pathophysiology: Clonal expansion of malignant hematopoietic precursor cells disrupts normal bone marrow function, causing cytopenias and systemic spread.
Care
- Prevention:
- Minimize exposure to known risk factors (e.g., radiation, benzene).
- Genetic counseling for high-risk families.
- Follow-up:
- Regular monitoring of blood counts and minimal residual disease (MRD). Long-term surveillance for relapse or secondary malignancies. Management of late effects from therapy (e.g., cardiac toxicity, infertility).
- Bone marrow failure effects: Anemia (fatigue, pallor, shortness of breath).
