60,700 (2015) [7] Chronic lymphocytic leukemia ( CLL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell ). [2] [8] Early on, there are typically no symptoms. [2] Later, non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss for no clear reason may occur.
Large granular lymphocytic (LGL) leukemia is a chronic lymphoproliferative disorder that exhibits an unexplained, chronic (> 6 months) elevation in large granular lymphocytes (LGLs) in the peripheral blood. It is divided in two main categories: T-cell LGL leukemia (T-LGLL) and natural-killer (NK)-cell LGL leukemia (NK-LGLL).
Richter's transformation (RT), also known as Richter's syndrome, is the conversion of chronic lymphocytic leukemia (CLL) or its variant, small lymphocytic lymphoma (SLL), into a new and more aggressively malignant disease. [1] CLL is the circulation of malignant B lymphocytes with or without the infiltration of these cells into lymphatic or ...
Aggressive NK-cell leukemia (ANKL) is a lymphoid leukemia that is a deficiency NK cells. Not very much is known about this disease due to its rarity, but it is highly aggressive. A majority of patients with NK cell leukemia die within a year of diagnosis, and for ANKL in particular, half of patients die within two months.
Monoclonal B-cell lymphocytosis. Monoclonal B-cell lymphocytosis (MBL) is an asymptomatic condition in which individuals have increased blood levels of particular subtypes of monoclonal lymphocytes (i.e. an aberrant and potentially malignant group of lymphocytes produced by a single ancestral cell). This increase must persist for at least 3 ...
Acute lymphoblastic leukemia (ALL) 4.0% Acute myeloid leukemia (AML) 8.7% Chronic lymphocytic leukemia (CLL) sorted under lymphomas according to current WHO classification; called small lymphocytic lymphoma (SLL) when leukemic cells are absent. 10.2% Chronic myelogenous leukemia (CML) 3.7% Acute monocytic leukemia (AMoL) 0.7% Other leukemias 3.1%
353,500 (2015) [8] Leukemia ( also spelled leukaemia and pronounced / luːˈkiːmiːə / [1] loo-KEE-mee-ə) is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. [9] These blood cells are not fully developed and are called blasts or leukemia cells. [2]
Hairy cell leukemia is an uncommon hematological malignancy characterized by an accumulation of abnormal B lymphocytes. [1] It is usually classified as a subtype of chronic lymphocytic leukemia (CLL). Hairy cell leukemia makes up about 2% of all leukemias, with fewer than 2,000 new cases diagnosed annually in North America and Western Europe ...
