Combination Chemotherapy With or Without G-CSF in Treating Patients With Relapsed Chronic Lymphocytic Leukemia

• Status: Terminated
• Trial end date: 2007-09-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as fludarabine, mitoxantrone, and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. Colony stimulating factors, such as G-CSF, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of combination chemotherapy. It is not yet known whether giving combination chemotherapy alone is more effective than combination chemotherapy together with G-CSF in treating patients with chronic lymphocytic leukemia.

PURPOSE: This randomized phase III trial is studying giving combination chemotherapy together with G-CSF to see how well it works compared to giving combination chemotherapy alone in treating patients with relapsed stage I, stage II, stage III, or stage IV chronic lymphocytic leukemia.
