CLL is a disorder where too many lymphocytes, a type of white blood cell, are produced. This disease results in the abnormal accumulation of lymphocytes in the marrow, the bloodstream and the lymphatic system. CLL always involves the bone marrow, frequently involves the lymph nodes and less often infiltrates the spleen.
Chronic lymphocytic leukemia (CLL) is a form of slowly-progressing leukemia, a disease characterized by an accumulation of abnormal lymphocytes, typically B-cells, in the blood and bone marrow. The malignant cells grow both in the bone marrow, where they can crowd out normal blood-producing cells, and the lymph nodes, where they can result in bulky and/or uncomfortable tumors.
Leukemia of mature lymphocytes. Mostly slowly progressive. Occurs mainly in older adults
slowly progressing cancer of the blood that affects lymphocytes
A slowly progressive form of lymphocytic leukemia, characterized by an increased number of the B lymphocytes in the marrow and blood. Enlargement of lymph nodes and the spleen occur commonly. It is the most prevalent form of leukemia and occurs predominantly after age 55 years. It may be diagnosed by chance before the patient develops any clinical symptoms of disease.
CLL. A common type of indolent (slowly progressing) cancer in which too many lymphocytes (white blood cells) are found in the peripheral blood and bone marrow. Most patients with CLL are older than 50 years and have no symptoms at the time of their diagnosis.
lymphocytic leukemia that is marked by an abnormal increase in the number of mature lymphocytes and especially B cells
(CLL) - A disease in which too many infection-fighting white blood cells called lymphocytes are found in the body. Chronic leukemia progresses more slowly than the acute form and has more mature-looking cancer cells.
The Condition"...The pattern of the lymphocytes in the biopsy of the marrow can be one useful factor in determining the probable rate of progression of the disease..."
chronic leukemia characterized by lymphoblast-like cells; more common in older men
CLL is a disease that makes immature lymphocytic cells. Unlike in acute lymphocytic leukemia (ALL), these cells can carry out some of their normal functions. As a result, chronic leukemia gets worse gradually.
The Condition"...When it occurs, it may affect the skin, nervous system and lymph nodes more often and is more rapidly progressive than is the B cell type..."
The Condition"...The report of an elevated white blood cell count is the most common clue that leads a physician to consider the diagnosis of chronic lymphocytic leukemia..."
A slowly progressing condition marked by the proliferation of abnormal white blood cells called lymphocytes; leaves the body susceptible to anemia, infection, and bleeding.
longer term over-production of white blood cells, most common in people over 65
See: Leukemia, chronic lymphocytic.
a disease caused by the overabundance of mature white blood cells (lymphocytes) in the body; most commonly found in adults
type of blood cancer that involves the overproduction of mature lymphocytes.
a slowly progressing malignancy of the blood in which too many lymphocytes, a type of white blood cell, are produced by the bone marrow and by organs of the lymph system.
A chronic leukemia affecting the lymphocytes (a type of white blood cell). Generally it occurs in older persons without symptoms and progresses slowly.
A slowly progressing form of leukemia characterized by an increased number of the type of white blood cells known as lymphocytes. It has variable symptoms and course, but may be diagnosed by chance before the patient develops any clinical symptoms of disease.
A cancer of the lymphocytes on the white blood cells. It usually occurs in persons over the age of 60. It is more common in men.
The Condition"...These large numbers of leukemic lymphocytes (white cells) can collect in the lymphatic system and the lymph nodes may become enlarged..."
The Condition"Each year, nearly 7,000 people in the United States learn that they have chronic lymphocytic leukemia..." Recommendation Selenium"In evaluating 59 patients with lymphoid malignancies such as Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma and chronic lymphocytic leukemia, serum selenium concentrations were significantly lower in patients than in controls..."
A slowly progressing disease in which too many white blood cells called lymphocytes are found in the body.
A type of lymphoma characterized by an uncontrolled accumulation of large numbers of lymphocytes (white blood cells) in the blood, bone marrow, lymph nodes, and other organs. CLL is usually referred to as leukemia because its initial effects are on the blood and bone marrow.
The Condition"...This change in the cell's DNA confers a growth and survival advantage on the cell, which becomes abnormal and malignant (leukemic)..."
The Condition"...These distinctions may be accounted for by the malignant transformation occurring after the common lymphocyte has differentiated into one of the three types of lymphocytes..."
Chronic lymphocytic leukemia (or "chronic lymphoid leukemia"), known for short as CLL, is a type of leukemia in which too many lymphocytes are produced. Although the malignant lymphocytes in CLL may look normal and mature, they are not and these cells may not cope effectively with infection.
