Overview

Most patients with chronic lymphocytic leukemia are initially asymptomatic. If left untreated, patients with chronic lymphocytic leukemia may progress to develop weight loss, fever, and lymph nodes swelling. Common complications of chronic lymphocytic leukemia include immunodeficiency, warm autoimmune hemolytic anemia, and Richter's transformation. Prognosis is generally good, and the 5-year survival rate of patients with chronic lymphocytic leukemia is 81.7%.

Natural History, Complications and Prognosis

Natural History

Most patients with chronic lymphocytic leukemia are initially asymptomatic.
If left untreated, patients with chronic lymphocytic leukemia may progress to develop weight loss, fever, and lymph nodes swelling.

Complications

Common complications of chronic lymphocytic leukemia include:^[1]^[2]^[3]^[4]

Richter's transformation
Recurrent infections
Anemia
- Autoimmune thrombocytopenia
- Red cell aplasia
- Chemotherapy-induced anemia
Immune thrombocytopenia
Colitis
Intussusception
Small intestinal bacterial contamination
Tumor lysis syndrome
Constrictive pericarditis

Prognosis

Prognosis is generally good, and the 5-year survival rate of patients with chronic lymphocytic leukemia is 81.7%.^[5]
Common prognostic factors for chronic lymphocytic leukemia patients include age, tumor stage, and the presence of certain genetic mutations.^[6]
The table below lists prognostic factors for chronic lymphocytic leukemia patients:^[7]^[8]^[1]


Prognostic Factor	Description

Age	Older age at the time of diagnosis is associated with a worse prognosis.
Gender	Males are associated with a worse prognosis when compared to females.
Performance status	Patient's poor performance status is associated with a worse prognosis.
Stage	Binet stages B and C or Rai stages 2-4 are associated with a worse prognosis.
Lymphocyte doubling time	A rapid lymphocyte doubling time is associated with a worse prognosis.
Genetic mutations	Deletion of chromosome 17 short arm and chromosome 11 long arm are associated with a worse prognosis.
Prolymphocytes percent	An increased percentage of prolymphocytes is associated with a worse prongnosis.
Histological analysis	Diffuse histology on bone marrow aspiration is associated with a worse prognosis.
Lactate dehydrogenase (LDH) level	Elevated level of LDH is associated with a worse prognosis.
β2-microglobulin level	Elevated level of β2-microglobulin is associated with a worse prognosis.
Lymphocyte surface markers	Over expression of CD38 is associated with a worse prognosis.
Immunoglobulin (Ig)VH gene	The absence of IgVH gene mutation is associated with a worse prognosis.
Membrane-bound proteins	The expression of zeta-chain-associated protein kinase 70 (ZAP) is associated with a worse prognosis.
