==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.

==Differentiating Leukemia from other Diseases==
==Differentiating Leukemia from other Diseases==
Leukemia must be differentiated from various diseases that cause [[weight loss]],  [[night sweats]], [[hepatosplenomegaly]], and palpable [[lymph node]]s, 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:<ref name="H">Hoffbrand V, Moss P. Essential Haematology. John Wiley & Sons; 2011</ref>

Overview

Leukemia (Greek leukos, “white”; haima, “blood”) can be defined as a group of hematopoietic stem cell malignancies due to genetic abnormalities that may lead to clonal proliferation of these cells. These group of diseases are classified based on the type of hematopoietic stem cell involved and the duration of the disease. The leukemias are the most common malignancies among children younger than 15 years. Among them, Acute Lymphoblastic Leukemia (ALL) is the most common leukemia and accounts for 77% of childhood leukemia. However, Chronic Lymphocytic Leukemia (CLL) is the most common form of leukemia in adults, and 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 result in 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 leukemia, prolymphocytic leukemia, 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]

Disease Etiology Clinical Manifestation Laboratory Findings Gold standard diagnosis Associated findings
Demography History Symptoms Signs Lab Histopathology

  • Clonal proliferation of malignant myeloid blast cells in the bone marrow
  • Genetic abnormalities t(8;21), inv(16), and t(15;17)
  • The most common leukemia in adults

  • The incidence of adult T-cell leukemia increases with age, and the median age at diagnosis is 57 years.
  • Males are more commonly affected with adult T-cell leukemia than females.
  • The male to female ratio is approximately 1.4 to 1.
