The systems of the body most affected by chemotherapy drugs include visual and semantic memory, attention and motor coordination and executive functioning. [9] [10] These effects can impair a chemotherapy patient's ability to understand and make decisions regarding treatment, perform in school or employment and can reduce quality of life. [10]
Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. [2] The risk is especially high in cytotoxic chemotherapy for leukemia. In the case of non-small-cell lung cancer, myelosuppression predisposition was shown to be modulated by enhancer mutations. [3]

This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Due to the high mortality of untreated TTP, a presumptive diagnosis of TTP is made even when only microangiopathic hemolytic anemia and thrombocytopenia are seen, and therapy is started. Transfusion is contraindicated in thrombotic TTP, as it fuels the coagulopathy. Since the early 1990s, plasmapheresis has become the treatment of choice for TTP.
[9] [10] There are three known genetic mutations that cause ET. The most common genetic mutation is a JAK2 mutation. Roughly 50% of the population of ET patients have this mutation. The JAK 2 gene signals a protein that promotes the growth of cells. The protein is part of a signaling pathway called the JAK/STAT pathway.
Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term thrombocythemia is used, as either primary thrombocythemia or essential thrombocythemia .
This is a shortened version of the fourth chapter of the ICD-9: Diseases of the Blood and Blood-forming Organs. It covers ICD codes 280 to 289. The full chapter can be found on pages 167 to 175 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Coagulopathy (also called a bleeding disorder) is a condition in which the blood's ability to coagulate (form clots) is impaired. [1] This condition can cause a tendency toward prolonged or excessive bleeding (bleeding diathesis), which may occur spontaneously or following an injury or medical and dental procedures.
