Chronic lymphocytic leukemia (CLL) is a type of cancer that affects the blood and bone marrow. [8] [9] In CLL, the bone marrow makes too many lymphocytes, which are a type of white blood cell. [8] [9] In patients with CLL, B cell lymphocytes can begin to collect in their blood, spleen, lymph nodes, and bone marrow.
In 2011, a year after treatment, two of the three people with advanced chronic lymphocytic leukemia were reported to be cancer-free [99] and in 2013, three of five subjects who had acute lymphocytic leukemia were reported to be in remission for five months to two years. [100]
Chronic leukemia is an increase of abnormal white blood cells. It differs from acute leukemia, and is categorized as myelogenous, lymphocytic or myeloproliferative. Chronic leukemia may refer to: Chronic myelogenous leukemia; Chronic lymphocytic leukemia, including Hairy cell leukemia
The lymphocyte subtypes are B-cells that share certain features with the abnormal clones of lymphocytes that circulate in chronic lymphocytic leukemia/small lymphocyte lymphoma (CLL/SLL) or, less frequently, other types of B-cell malignancies. Some individuals with these circulating B-cells develop CLL/SLL or the lymphoma types indicated by ...
Signs and symptoms of chronic lymphocytic leukemia commonly precede those of multiple myeloma, sometimes by years. [38] The relationship between the two clones of cells in this combined disease has not been established although one study suggests that the clonal plasma cells and clonal lymphocytes arise from a common hematological stem cell. [39]
A B-cell leukemia is any of several types of lymphoid leukemia which affect B cells. [1] Types include (with ICD-O code): [citation needed] 9823/3 – B-cell chronic lymphocytic leukemia/small lymphocytic lymphoma; 9826/3 – Acute lymphoblastic leukemia, mature B-cell type; 9833/3 – B-cell prolymphocytic leukemia
Indolent chronic lymphocytic leukemia or indolent CLL, which is a slow-progressing blood and bone marrow cancer, [2] Indolent lymphoma or low-grade lymphoma, a type of slow-growing non-Hodgkin lymphoma or slow-growing NHL. [3]
Lymphoproliferative disorders are a set of disorders characterized by the abnormal proliferation of lymphocytes into a monoclonal lymphocytosis.The two major types of lymphocytes are B cells and T cells, which are derived from pluripotent hematopoietic stem cells in the bone marrow.
