Thalidomide in Treating Patients With Asymptomatic, Indolent Non-Hodgkin's Lymphoma or Chronic Lymphocytic Leukemia

OBJECTIVES:

• Determine the feasibility, in terms of toxicity and patient compliance, of thalidomide in patients with asymptomatic, indolent non-Hodgkin's lymphoma or chronic lymphocytic leukemia.
• Determine the event-free and progression-free survival of patients treated with this drug.
• Determine disease response and time to next treatment in patients treated with this drug.
• Determine the quality of life of patients treated with this drug.

OUTLINE: Patients receive oral thalidomide once daily. Treatment continues for 18 months in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline, monthly during study, and at the end of the study.

PROJECTED ACCRUAL: A total of 30-36 patients will be accrued for this study within 2 years.
