Lumbar puncture helps identify leukemic cells in the cerebrospinal fluid (CSF). [3] Even if leukemic cells are not found in the CSF at the time of diagnosis, it is highly likely that they will spread there over time. Thus, prophylactic intrathecal chemotherapy, a treatment to lower the risk of leukemia spreading to the spinal cord and brain by ...
Acute lymphoblastic leukemia (ALL) is a cancer of the lymphoid line of blood cells characterized by the development of large numbers of immature lymphocytes. [1] Symptoms may include feeling tired, pale skin color, fever, easy bleeding or bruising, enlarged lymph nodes, or bone pain. [1]
[4] [5] If lumbar puncture is performed this may show increased protein levels but no white blood cells. [1] [3] [4] Computed tomography scanning may be performed in the first instance; this may show low density white matter areas in the posterior lobes. [4] The diagnosis is typically made with magnetic resonance imaging of the brain.
Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and
CLL is the most common type of leukemia in the UK, accounting for 38% of all leukemia cases. Approximately 3,200 people were diagnosed with the disease in 2011. [91] In Western populations, subclinical "disease" can be identified in 3.5% of normal adults, [92] and in up to 8% of individuals over the age of 70. [93]
Whereas acute leukemia must be treated immediately, chronic forms are sometimes monitored for some time before treatment to ensure maximum effectiveness of therapy. Chronic leukemia mostly occurs in older people but can occur in any age group. Additionally, the diseases are subdivided according to which kind of blood cell is affected.
CSF cytology: is performed after drawing the CSF by lumbar puncture. Cytogenetic: measures chromosomal content of cells and fluorescence in situ hybridization which detects numerical and structural genetic aberrations as a sign of malignancy. This is especially useful for liquid tumors such as leukemia and lymphoma.
For the analysis of cerebrospinal fluid, a sample is first collected via lumbar puncture (LP). Normally it is assumed that all the proteins that appear in the CSF, but are not present in the serum, are produced intrathecally (inside the central nervous system). Therefore, it is normal to subtract bands in serum from bands in CSF when ...
