Title: Lenalidomide (Revlimid) in Patients With Previously Treated Chronic Lymphocytic Leukemia
Brief Summary: The goal of this clinical research study is to learn if lenalidomide (Revlimid®) can help to control CLL in patients who have already received standard therapy. The safety of lenalidomide will also be studied.

1. Diagnosis of CLL/SLL that meets IWCLL diagnostic criteria.
2. Age 65 yrs and older OR if less than 65 years, must have at least one of the following criteria:

   * Cumulative Illness Rating Score (CIRS) \>6

LDT may be obtained by linear regression extrapolation of absolute lymphocyte counts obtained at intervals of 2 weeks over an observation period of 2 to 3 months. In patients with initial blood lymphocyte counts of \<30,000/µL, LDT should not be used as a single parameter to define indication for treatment.
