RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Alternating treatment with more than one drug may kill more cancer cells.

PURPOSE: Phase II trial to study the effectiveness of fludarabine alternating with cyclophosphamide in treating patients who have previously untreated chronic lymphocytic leukemia.

Condition Intervention Phase
Drug: cyclophosphamide
Drug: fludarabine phosphate
Phase 2

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: `A Phase II Study of Alternating Cycles of Fludarabine and Cyclophosphamide in Previously Untreated Patients With B-Cell CLL

Detailed Description:

OBJECTIVES: I. Determine the rate and duration of complete and partial remissions in patients with previously untreated B-cell chronic lymphocytic leukemia after treatment with alternating courses of fludarabine and cyclophosphamide. II. Monitor and assess toxicity of this regimen in these patients. III. Utilize molecular genetic studies and flow cytometry on peripheral blood cells from patients achieving complete remission by conventional criteria. IV. Apply FISH techniques using probes to chromosomes 12 and 13 as prognostic factors for time to progression and overall survival of these patients.

OUTLINE: Patients receive alternating courses of fludarabine and cyclophosphamide. Fludarabine is administered IV over 10-30 minutes on days 1-5 of courses 1, 3, and 5. Cyclophosphamide is administered IV over 30-60 minutes on day 1 of courses 2, 4, and 6. Treatment repeats every 4 weeks. Patients achieving clinical complete remission (CCR) after 6 courses of chemotherapy receive 2 additional courses (one course of each drug). Patients achieving partial remission after 6 courses of chemotherapy also receive 2 additional courses. If these patients then achieve CCR, they receive another 2 courses. Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study within 22 months.
