Overview
The mainstay of therapy for symptomatic chronic lymphocytic leukemia patients is immunochemotherapy. Asymptomatic chronic lymphocytic leukemia patients are managed with observation and follow-up, whereas symptomatic chronic lymphocytic leukemia patients are treated with immunochemotherapy. Immunochemotherapies used for the treatment of chronic lymphocytic leukemia patients include purine analogues, alkylating agents, monoclonal antibodies, corticosteroids, tyrosine kinase inhibitors, and B-cell receptor pathway inhibitors. Radiation therapy is not recommended for the management of chronic lymphocytic leukemia patients.
Immunochemotherapy
- The mainstay of therapy for symptomatic chronic lymphocytic leukemia patients is immunochemotherapy.
- 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:
- 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 might be observed as:
- An increase of greater than 50% over a 2-month period
- A lymphocyte doubling in a period shorter than six months
- Immunochemotherapeutic agents used for the treatment of chronic lymphocytic leukemia patients include:
- Purine analogues such as:
- Alkylating agents such as:
- Monoclonal antibodies such as:
- Immunomodulatory agents such as:
- Corticosteroids such as:
- Tyrosine kinase and B-Cell receptor pathway inhibitors such as:
- Idelalisib (targets phosphoinositide 3-kinase delta)
- Ibrutinib (targets bruton tyrosine kinase)
- The optimal immunochemotherapeutic regimen used for the management of chronic lymphocytic leukemia patients depends on a number of factors which include:
- 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:
