Study Notes
Diagnosis of Acute Lymphoblastic Leukemia (ALL)
- Lumbar puncture aids in detecting CNS involvement and ensures accurate diagnosis of ALL.
- Molecular tests help identify specific genetic alterations and assist in prognostic assessment.
- Bone marrow aspiration and biopsy are performed to evaluate the extent of leukemic infiltration in the bone marrow.
Key Symptoms and Signs of ALL
- Common symptoms of ALL include fatigue, fever, easy bruising, and bleeding.
- Symptoms that are NOT typically associated with ALL should be identified for accurate diagnosis.
Philadelphia Chromosome
- The presence of the Philadelphia chromosome is significant as it indicates a specific genetic mutation associated with a poorer prognosis in ALL.
- Targeted therapies are available for Philadelphia chromosome-positive (Ph+) ALL.
Prevalence and Demographics
- Acute lymphoblastic leukemia represents approximately 25% of all leukemia cases in children under 15 years of age.
- The most common type of ALL is B-cell ALL, whereas T-cell ALL is less frequent.
- Differences in ALL incidence between racial groups may be attributed to genetic, environmental, or socio-economic factors.
Morphological Subtypes
- The French-American-British (FAB) classification of ALL includes three morphological subtypes: L1, L2, and L3.
- Among these, the L1 subtype is the most common.
Prognostic Factors
- Key factors affecting the prognosis of ALL include age at diagnosis, white blood cell count, and cytogenetic findings.
- The most common cause of ALL remains unclear, although genetic predispositions and environmental factors play roles.
Imaging and Treatment
- Common imaging tests used in ALL diagnosis may include X-rays, CT scans, and MRI; however, certain imaging modalities may not be relevant.
- Intrathecal chemotherapy is often administered directly into the spinal canal to target CNS leukemia.
