Therapeutic Options for a Patient With Previously Untreated Chronic Lymphocytic Leukemia

Release Date: May 31, 2009
Expiration Date: May 31, 2010

Interactive Case Study Overview

Chronic lymphocytic leukemia (CLL) is the most common leukemia in the United States, accounting for nearly 35% of all leukemias. Patients with CLL exhibit a highly variable clinical course, and 80% have low-risk disease at diagnosis. Risk stratification is therefore an essential aid in the selection of optimal treatment strategies. Prognosis of patients with CLL has been correlated with age, sex, and Binet/Rai stage; however, an array of molecular and biologic characteristics have been recently identified that offer important independent prognostic information. Gene profiling analyses have identified 5 genetic risk factors. Patients with CLL who harbor a deletion of chromosome 17p13 (del[17p13]) or del(11q22) alone or in combination with other cytogenetic abnormalities have the worst prognosis, whereas patients with del(13q14) as a sole abnormality have the best prognosis. The prognostic use of these molecular and cytogenetic parameters is being validated in prospective clinical trials. In recent years, purine analogue–based chemotherapy and chemoimmunotherapies incorporating monoclonal antibodies targeting CD20 and/or CD52 have improved clinical outcomes for patients with CLL. Response to these treatment regimens is being further correlated with cytogenetic risk factors in order to determine the optimal treatment strategy for these patients. The eradication of minimal residual disease is increasingly being recognized as a therapeutic goal and is being assessed routinely in the management of patients with CLL.

The purpose of this activity is to apprise physicians of risk-stratification strategies based on molecular and cytogenetic features in the management of patients with CLL.
