Leukemia | any malignant blood disorder in which leukocytes (WBC), usually in an immature form, proliferate (grow) unregulated; often with decreased erythrocytes (RBC) and platelets |
4 Types of Leukemia | ALL, CLL, AML, CML |
ALL (Acute Lymphocytic Leukemia) | onset usually younger than 5, rarely over 15; increased lymphocytes, decrease RBC and platelets |
CLL (Chronic Lymphocytic Leukemia) | onset older than 40; increased lymphocytes, normal or low RBC and platelets; most common type in adults |
AML (Acute Myelogenous Leukemia) | all age ranges; decrease in myeloid formed cells (monocytes, granulocytes, RBC and platelets) |
CML (Chronic Myelogenous Leukemia) | onset older than 20, increasing with age; genetic link, same as AML but greater number of normal cells |
Leukemia signs and symptoms | fatigue from anemia (low RBC, tired, pale, fragile, cold, low o2); infections (low/immature WBC); bruising (low platelets); spleen & lymph enlargement (from infection); nose bleeding, mouth and GI tract (low platelets) |
Leukemia treatment | chemotherapy, bone marrow transplant, stem cell transplant |
Multiple Myeloma | malignancy involving plasma cells or B-lymphocyte cells in the bone marrow; poor prognosis w/estimated survival of 1-5 years |
Multiple Myeloma treated by | steroids/chemo, bone marrow transplants; treatment doesn't cure, but prolongs life |
Multiple Myeloma Pathophysiology | osteoclast breaks down bone cells, abnormal plasma cells release osteoclast, release proteins that damage kidneys and reduce production of antibodies |
