Symptoms and Leukemia Diagnostic Laboratory ~ Leukemia, cancer of the blood forming tissues is the most common form of cancer in children. However, even for a child with the most favorable prognosis, this countless physical leukemia, clinic, physician office and the community can do much to prevent problems and reduce others.
Evaluation
Leukemia is a general term given to a group of malignant lymph system and bone marrow. The following is an overview of the immunological morphologic leukemia, cyto-chemical.
Morphological and cytochemical markers
Leukemia is classified according to their predominant cell type and level of maturity. As described by the following:
Lymphoma or lymphocytic leukemia involving the lymphatic system.
Mielo for those of myeloid (bone marrow) Original
Blast and acute- for immature cells involving
And chronic cystic those involving mature cells
In children, two forms are generally recognized: acute lymphoblastic leukemia (ALL) and acute non-lymphocytic leukemia (myelogenous) (LANL or AML). Synonyms for all include lymphatic, lumphocytic, lymphoblastic leukemia and lymph-blast. In general, the term "stem cells" or "leukemic blasts" also refers to the nature of lymphocytic leukemia. Synonyms for Type LANL include granulocytic, myelo-cytic, monocytic myeloid, and mono-myeloid monoblástica. There are also rarer forms of leukemia that are named for the specific cell involved, such as basophils or eosinphilic leukemia.
Because of the confusion and inconsistencies in classifyin leukemia, acute lymphoblastic leukemia and acute lymphoblastic non are subdivided according to another system known as the French-American-British system (FAB). Types with the best prognosis are Mi, acute myeloid leukemia without differentiation, and Mz, myelotic acute leukemia differentiation.
The different cells show differing reactions when exposed to certain chemicals. For example, lymphoblasts show no reactivity to Sudan black stain and peroxidase, whereas myeloblasts demonstrate the reactivity at a time.
Another important distinction between the types of cells is the absence or presence of Auer rods, granules containing RNA that appear in the cytoplasm of affected myeloblasts and promyelocytes. His presence is a strong diagnostic indicator for certain types of ANLL and is associated with a better prognosis.
Leukocyte count and sternal puncture. The key dates are:
• Leukocytosis (with levels of leukocytes 40-100x1o ^ 6) or leukopenia
• Source hypoplastic anemia
• Thrombocytopenia
• White blood cell count (explosions can be seen in the peripheral blood)
• Bone marrow aspirates blasts are higher than 20%
That about the main Symptoms and Leukemia Diagnostic Laboratory, greetings always healthy.
