Overview
The mainstay of therapy for symptomatic chronic lymphocytic leukemia patients is immunochemotherapy.[1] Asymptomatic chronic lymphocytic leukemia patients are managed with observation and follow-up, whereas symptomatic chronic lymphocytic leukemia patients are treated with immunochemotherapy. Immunochemotherapies for chronic lymphocytic leukemia include purine analogues, alkylating agents, monoclonal antibodies, steroids, corticosteroids, Tyrosine kinase inhibitors, and B-cell receptor pathway inhibitors.[1][2] Radiation therapy is not recommended for the management of chronic lymphocytic leukemia patients.[3][4][5]
Immunochemotherapy
- The mainstay of therapy for symptomatic chronic lymphocytic leukemia patients is immunochemotherapy.[1][4][5]
- Asymptomatic chronic lymphocytic leukemia patients are managed with observation and follow-up, whereas symptomatic chronic lymphocytic leukemia patients are treated with immunochemotherapy.
- Indications to initiate immunochemotherapy among patients with chronic lymphocytic leukemia include:[3]
- Symptomatic chronic lymphocytic leukemia patients presenting with:
- Fever of unknown origin (>38.1°C for a period greater than two weeks)
- Night sweats for more than one month
- Unintentional significant weight loss over a period of six months
- Patients presenting with thrombocytopenia or anemia due to bone marrow failure
- Patients presenting with refractory autoimmune hemolytic anemia or refractory autoimmune thrombocytopenia
- Evidence of symptomatic splenomegaly, with the spleen being palpated more than 6cm below the costal margin
- Evidence of symptomatic progressive lymph nodes swelling, with a size greater than 10 cm in diameter
- Evidence of a rapidly progressive lymphocytosis, which may be indicated by:
- An increase of greater than 50% over a 2-month period
- A lymphocyte doubling period shorter than six months
- Immunochemotherapies for chronic lymphocytic leukemia include purine analogues, alkylating agents, monoclonal antibodies, steroids, corticosteroids, Tyrosine kinase inhibitors, and B-cell receptor pathway inhibitors.[1][2]
- Purine analogues used for the management of chronic lymphocytic leukemia patines may include:
- Alkylating agents used for the management of chronic lymphocytic leukemia patients may include:
- Monoclonal antibodies used for the management of chronic lymphocytic leukemia patients may include:
- Immunomodulatory agents used for the management of chronic lymphocytic leukemia patients may include:
- Corticosteroids used for the management of chronic lymphocytic leukemia patients may include:
- Tyrosine kinase and B-Cell receptor pathway inhibitors used for the management of chronic lymphocytic leukemia patients may include:
- Idelalisib (targets phosphoinositide 3-kinase delta)
- Ibrutinib (targets bruton tyrosine kinase)
- The optimal immunochemotherapeutic regimens used for the management of chronic lymphocytic leukemia depends on a number of factors which include:[3][4][5]
- The clinical presentation of the patients
- The performance status of the patients
- The stage of the tumor
- The presence of specific genetic mutations
- First line therapy vs. refractory/relapsed therapy
- The algorithm below summarizes the management approach for chronic lymphocytic leukemia patients:[1][2][3]
