Essential Thrombocythemia (ET) Is a Chronic Disease That May Shorten Survival Over Time. Essential thrombocythemia may be caused by a person acquiring (not inheriting) a somatic mutation in any of several genes, such as the JAK2 gene (most frequently), CALR gene, and rarely, the MPL, THPO, or TET2 gene. The reason why some people acquire mutations that cause the disease is unknown. 1,2 In general, ET is a chronic disease that does not shorten life expectancy in the first decade following diagnosis; however, over longer periods of time, survival may be shortened. Treatment generally revolves around preventing clotting or excessive bleeding. Introduction. Therefore, elevated platelet counts (>450 x 10 9 /l) require careful diagnostic work-up to differentiate between reactive thrombocytosis (RT), caused by various conditions, and essential thrombocythemia (ET), a myeloproliferative neoplasm (MPN).

Patient does not require treatment but those who are high risk of thrombosis and bleeding requires immediate care. For high platelet count, it can be reduce through using of hydroxyurea (also known as hydroxycarbamide), interferon-a or anagrelide as a superior treatment it has low risk of thrombosis. Despite a major molecular response, the patient developed a thrombocytosis. Deregulated Janus Kinase 2 (JAK2) activation is central to the pathogenesis of most MPNs, including ET. A fully normal platelet count isn't necessary to prevent bleeding, even with severe cuts or accidents. CancerConnect News: By interfering with protein signaling linked to blood cell production, Jakafi (ruxolitinib) may be effective in the treatment of essential thrombocythemia (ET) in patients who progress on or cant tolerate Hydrea (hydroxyurea). Considering taking medication to treat essential thrombocytosis? Essential thrombocythemia is a rare and chronic condition where there is excessive production of blood platelets in the body.

The elevation in the amount of platelets may not be long-lasting if the cause is a recent injury or an operation that is the cause of significant loss of blood. Thrombocytosis is known as an increase in the number of platelets circulating in the blood stream. Thrombocytosis is an adverse prognostic factor in many types of cancer. There is evidence that interventions early in the disease in people without symptoms affect the outcome or improve survival.
