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.
Lymphoid leukemias are a group of leukemias affecting circulating lymphocytes, a type of white blood cell.The lymphocytic leukemias are closely related to lymphomas of the lymphocytes, to the point that some of them are unitary disease entities that can be called by either name (for example, adult T-cell leukemia/lymphoma).
The key factor that distinguishes low-count CLL/SLL-MLB, high-count CLL/SLL-MLB, and CLL/SLL is the number of circulating monoclonal B cells, as described above. However, the other MLB phenotypes may progress to and/or be mimicked by various monoclonal B-cell lymphocyte malignancies.
CLL/SLL is the most common adult leukemia in Western countries, accounting for 1.2% of the new cancers diagnosed each year in the United States. It usually occurs in older adults (median age at diagnosis 70) and follows an indolent course over many years. [11] About 1-10% of CLL/SLLs develop a Richter's transformation at a rate of 0.5–1% per ...
Aggressive NK-cell leukemia is a disease with an aggressive, systemic proliferation of natural killer cells (NK cells) and a rapidly declining clinical course. [ 1 ] [ 2 ] [ 3 ] It is also called aggressive NK-cell lymphoma .
The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. [1] [2] A minority of cancers are due to inherited genetic mutations. [3] Most cancers are related to environmental, lifestyle, or behavioral exposures. [4] Cancer is generally not contagious in humans, though it can be caused by oncoviruses and cancer ...
Chronic lymphocytic leukemia (CLL) and small cell lymphocytic lymphoma (SLL) are different manifestations of the same disease and are managed in the same way. [21] When the abnormal lymphocytes are located mostly in the lymph nodes, it is referred to as SLL; when the abnormal lymphocytes are mostly in the blood and bone marrow, it is called CLL.
It is divided in two main categories: T-cell LGL leukemia (T-LGLL) and natural-killer (NK)-cell LGL leukemia (NK-LGLL). As the name suggests, T-cell large granular lymphocyte leukemia is characterized by involvement of cytotoxic- T cells ).
