RATIONALE: Drugs used in chemotherapy, such as chlorambucil and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known whether chlorambucil is more effective than fludarabine in treating Waldenström macroglobulinemia, splenic lymphoma, or lymphoplasmacytic lymphoma.

PURPOSE: This randomized phase III trial is studying chlorambucil to see how well it works compared with fludarabine as first-line therapy in treating patients with previously untreated Waldenström macroglobulinemia, splenic lymphoma, or lymphoplasmacytic lymphoma.

Condition Intervention Phase
Lymphoma Drug: chlorambucil Drug: fludarabine phosphate Procedure: quality-of-life assessment Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomised Trial of Chlorambucil Versus Fludarabine as Initial Therapy of Waldenström's Macroglobulinaemia and Splenic Lymphoma With Villous Lymphocytes

Estimated Enrollment: 400
Study Start Date: June 2006
Study Completion Date: January 2013
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Detailed Description:


  • Compare the efficacy of first-line therapy comprising chlorambucil vs fludarabine phosphate in patients with previously untreated Waldenström macroglobulinemia, splenic lymphoma with villous lymphocytes, or non-IgM lymphoplasmacytic lymphoma.

OUTLINE: This is a multicenter study. Patients are stratified according to disease (Waldenström macroglobulinemia vs splenic lymphoma with villous lymphocytes vs non-IgM lymphoplasmacytic lymphoma). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral chlorambucil on days 1-10. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
  • Arm II: Patients receive fludarabine phosphate orally or IV on days 1-5. Treatment repeats every 28 days for 3-6 courses in the absence of disease progression or unacceptable toxicity.

Patients undergo quality of life assessment at baseline.
