Brief Summary

Chronic lymphocytic leukemia. B-cell chronic lymphocytic leukemia (B-CLL) is the most prevalent leukemia in the Western Hemisphere, accounting for \~25% of all leukemia's. It represents a monoclonal expansion of small, long-lived, apparently slowly dividing CD5+ B cells. Because of the low proliferative index and a presumed uniform proliferative rate of B-CLL cells in vivo (a fact not yet tested or documented), B-CLL appears to be primarily a disease of accumulation rather than proliferation.

Outcome Measures

Primary Outcomes (1)

  • B Cell Chronic Lymphocytic Leukemia Subgroups: Direct measurement of leukemic cell turnover (synthesis and removal) using deuterated water as a DNA-labeling agent in patients with chronic lymphocytic leukemia

    We believe that the results of these studies may identify in vivo correlates of the in vitro studies we have performed previously. Kinetic analyses may be another way to identify patients with different levels of risk from this disease and thereby provide an additional prognostic parameter. This information may also help to individualize future therapies for specific patients based on the in vivo biology in their particular B-CLL clone.

Chronic Lymphocytic Leukemia

You may qualify if:

  • Must be 18 years of age.
  • Must meet the clinical and laboratory criteria for B-CLL (i.e., compatible clinical history and physical exam, presence of lymphocytosis, i.e., \>10,000 lymphocytes / mm3, evidence for a monoclonal population of CD5+/CD19+/CD23+ cells in the periphery that have dim surface membrane lg with L chain isotype restriction).
  • All patients will be staged according to the system of Rai. Only new onset patients who are not receiving therapy will be entered into the heavy water leukemic cell turnover studies.

You may not qualify if:

  • Patients hospitalized for an acute medical problem, related or not to their leukemia, within 4 weeks of enrollment.
  • A history of a second malignancy involving the hematopoietic system, or the need for extensive chemotherapy for any second malignancy; patients with active immunologic disorders (e.g., HIV and AIDS), especially autoimmune problems (e.g., autoimmune hemolytic anemia of any cause other than B-CLL).
  • Patients with impaired decision-making capabilities, e.g. dementia, psychosis, alcoholism, and illicit drug use will also be excluded.
