Topic: Thrombocytosis


  
  Thrombocytosis: Encyclopedia of Medicine
Thrombocytosis is a blood disorder in which the body produces a surplus of platelets (thrombocytes).
Thrombocytosis is an abnormally increased number of platelets in the blood.
Complications of thrombocytosis include stroke, heart attack, and formation of blood clots in the arms and legs.

 eMedicine - Thrombocytosis : Article by Susumu Inoue, MD   (Site not responding. Last check: 2007-10-10)
Primary thrombocytosis is a component of a myeloproliferative disorder (eg, essential thrombocythemia, myelofibrosis with myeloid metaplasia, polycythemia vera, chronic myelocytic leukemia [rare]) or, in rare cases, of acute myelocytic leukemia.
In pediatrics, primary thrombocytosis is exceedingly rare, whereas secondary, or reactive, thrombocytosis is common, particularly in infants.
Older children with thrombocytosis with thrombosis (suspected or demonstrated) or a history of thrombosis, increased bleeding tendency despite thrombocytosis, or splenomegaly must promptly be referred to a hematologist.

 Thrombocytosis: A clinical marker of tumor aggressiveness in renal cell carcinoma
Thrombocytosis: A clinical marker of tumor aggressiveness in renal cell carcinoma
Thrombocytosis correlated with increasing T stage (p< 0.001), increasing Fuhrman grade (p< 0.001), increasing tumor size (p< 0.001), nodal involvement (p< 0.001), and the presence of metastases (p= 0.01).
Thrombocytosis clearly is associated with a worse prognosis in renal cell carcinoma patients in this and other reports in the literature.

 `Thrombocytosis Herbal Remedy from Robert McDowell's Herbal Treatments
Thrombocytosis results in an increased numbers of platelets in the blood stream, normally they should range between 150 - 400 mill per ml of blood, with thrombocytosis the platelets can amount to between 400mill.
Three basic causes may be responsible for thrombocytosis: it may be a temporary response to a change in the body’s chemistry; it may be a reaction to a disorder or disease in another part of the body; or it may be a symptom of an underlying disease in the bone marrow.
Temporary thrombocytosis may occur in response to exercise, pregnancy and delivery, or other factors causing elevated blood levels of the hormone epinephrine.

 CancerNetwork:
To determine whether thrombocytosis played a role in ovarian cancer tumor growth and metastasis, the investigators examined the records of 183 consecutive patients with and without thrombocytosis who had undergone surgery for advanced ovarian cancer.
They found that 41 of the 183 patients demonstrated thrombocytosis prior to surgery and that those with the disorder had higher CA-125 levels, more advanced-stage disease, higher-grade tumors, and a greater tendency that their cancer had spread to the lymph nodes.
Although surgery successfully removed most of the cancer in 87% of all patients with and without thrombocytosis, the investigators found that almost half of the patients with thrombocytosis prior to surgery demonstrated a greater degree of residual cancer after surgery.

 Thrombocytosis: Patient Information: Arizona Telemedicine Program
Thrombocytosis is defined as an elevated level of platelets in the blood.
Thrombocytosis as a reaction to another disorder in the body results from increased production of platelets in the marrow and increased release of stored platelets from the spleen.
Thrombocytosis is diagnosed by patient history, physical examination for signs of disease, and laboratory testing.

 Essential Thrombocythemia: Myeloproliferative Disorders: Merck Manual Professional
To distinguish from other myeloproliferative disorders that produce thrombocytosis, the diagnosis of ET requires a normal Hct, MCV, and iron studies; absence of the Philadelphia chromosome and ABL-BCR translocation (present in chronic myelocytic leukemia); and absence of teardrop-shaped RBCs and significant increase in bone marrow fibrosis (present in idiopathic myelofibrosis).
Unlike ET, thrombocytosis does not increase the risk of thrombotic or hemorrhagic complications unless patients have severe arterial disease or prolonged immobility.
With secondary thrombocytosis, the platelet count is usually < 1,000,000/μL, and the cause may be obvious from the history, physical examination, or radiologic or blood testing.

 Thrombocytosis and essential thrombocythaemia
Thrombocytosis is a medical term used to describe a high number of platelets in your blood.
In thrombocytosis, the platelet count is more than 400 million per ml; rarely, it can reach 5000 million per ml.
The thrombocytosis usually resolves as the infection recovers, although it may take longer to settle.

 AccessMedicine - Harrison's Internal Medicine: Essential Thrombocytosis
"Essential thrombocytosis (other designations include essential thrombocythemia, idiopathic thrombocytosis, primary thrombocytosis, hemorrhagic thrombocythemia) is a clonal disorder of unknown etiology involving a multipotent hematopoietic progenitor cell and is manifested clinically by the overproduction of platelets without a definable cause.
Clinical recognition of thrombocytosis is unlikely in the largely asymptomatic persons affected by this disorder.
As a consequence, essential thrombocytosis was formerly considered to be a disease of the elderly and to be responsible for significant morbidity due to hemorrhage or thrombosis.

Although surgery successfully removed most of the cancer in 87 percent of all patients with and without thrombocytosis, the investigators found that almost half the patients with thrombocytosis prior to surgery demonstrated a greater degree of residual cancer after the operation.
Further, the patients with thrombocytosis remained disease-free for only about 38 months, while those without the disorder were free of cancer for approximately 49 months - nearly a year longer.

— Reactive thrombocytosis (RT) refers to thrombocytosis in the absence of a chronic myeloproliferative or myelodysplastic disorder, in patients who have a medical or surgical condition likely to be associated with an increased platelet count, and in whom the platelet count normalizes, or is expected to normalize, after resolution of this condition.
