This complementary and alternative medicine (CAM) information summary provides an overview of the use of coenzyme Q10 in cancer therapy. The summary includes a history of coenzyme Q10 research, a review of laboratory studies, and data from investigations involving human subjects. Although several naturally occurring forms of coenzyme Q have been identified, Q10 is the predominant form found in humans and most mammals, and it is the form most studied for therapeutic potential. Thus, it will be the...
Although cytogenetic abnormalities are found in as many as 80% of the patients with aCML, none is specific.[1,2,3,5] No Philadelphia chromosome or BCR/ABL fusion gene exists.
The exact incidence of aCML is unknown. The median age at the time of diagnosis of this rare leukemic disorder has been reported to be in the seventh or eighth decade of life.[1,2,3]
Morphologically, aCML is characterized by myelodysplasia associated with bone marrow and peripheral blood patterns similar to chronic myelogenous leukemia, but cytogenetically it lacks a Philadelphia chromosome or BCR/ABL fusion gene. The white blood cell count in the peripheral blood is variable. Median values range from 35 × 109 /L to 96 × 109 /L, and some patients may have white blood cell counts greater than 300 × 109 /L.[1,2,3,5] Blasts in the peripheral blood typically account for less than 5% of the white blood cells. Immature neutrophils usually total 10% to 20% or more. The percentage of monocytes is rarely more than 10%. Minimal basophilia may be present.[1,2,3,5] Nuclear abnormalities, such as acquired Pelger-Huët anomaly, may be seen in the neutrophils. Moderate anemia (often showing changes indicative of dyserythropoiesis) and thrombocytopenia are common.[1,2,3,4] Bone marrow findings include the following: [1,2,3,5]
Blast count less than 20%.
Erythroid precursors accounting for more than 30% of marrow cells with dyserythropoiesis present (in some cases).
