==[[Leukemia overview|Overview]]==
==Overview==
'''Leukemia''' (Greek leukos, “white”; haima, “blood”) could be defined as a group of [[hematopoietic stem cell]] [[malignancies]] that [[genetic]] abnormalities may lead to clonal proliferation of these cells. These group of diseases are classified based on type of [[hematopoietic stem cell]] involvement and duration of disease. The leukemias are the most common malignancies among children younger than 15 years. Among them, [[ALL]] is the most common leukemia accounts for 77% of childhood leukemia. However, [[CLL]] is the most common form of leukemia in adults, it accounts for 30% of all leukemias in the United states. The increased rate of proliferation and decreased rate of [[apoptosis]] in this progeny of cells may compromise normal [[bone marrow]] function and ultimately marrow failure. Clinical manifestations, diagnosis, laboratory findings, and therapy are different according to the type of malignancy.

Overview

Leukemia (Greek leukos, “white”; haima, “blood”) could be defined as a group of hematopoietic stem cell malignancies that genetic abnormalities may lead to clonal proliferation of these cells. These group of diseases are classified based on type of hematopoietic stem cell involvement and duration of disease. The leukemias are the most common malignancies among children younger than 15 years. Among them, ALL is the most common leukemia accounts for 77% of childhood leukemia. However, CLL is the most common form of leukemia in adults, it accounts for 30% of all leukemias in the United states. The increased rate of proliferation and decreased rate of apoptosis in this progeny of cells may compromise normal bone marrow function and ultimately marrow failure. Clinical manifestations, diagnosis, laboratory findings, and therapy are different according to the type of malignancy.

Differentiating Leukemia from other Diseases

Leukemia must be differentiated from various diseases that cause weight loss, night sweats, hepatosplenomegaly, and palpable lymph nodes, such as hairy cell leukaemia, prolymphocytic leukaemia, follicular lymphoma, and mantle cell lymphoma. Based on the expression of cell surface markers, the table below differentiates different types of leukemia from other diseases that cause similar clinical presentations:[1]
