简要总结
RATIONALE: Pentostatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving pentostatin together with cyclophosphamide and rituximab may kill more cancer cells.
PURPOSE: This phase II trial is studying the side effects and how well giving pentostatin together with cyclophosphamide and rituximab works in treating patients with previously untreated chronic lymphocytic leukemia.
详细描述
OBJECTIVES:
- To determine the frequency of response in patients with previously untreated, intermediate- or high-risk B-cell chronic lymphocytic leukemia (CLL) treated with pentostatin, cyclophosphamide, and rituximab.
- To characterize the toxicity of this regimen in these patients.
OUTLINE: Patients receive cyclophosphamide IV followed by pentostatin IV on day 1 in course 1. Beginning in course 2 and in all subsequent courses, patients receive cyclophosphamide IV on day 1, pentostatin IV on day 1, and rituximab IV on day 1 or on days 1 and 2. Treatment repeats every 3 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed at least every 3 months for 1 year.

主要结局
Overall Objective Response
时间窗: 2 years
The major criteria for determination of response to therapy in patients with CLL include physical examination and examination of the peripheral blood and bone marrow. Radiographic studies are not required but those that were abnormal pre-treatment, will be repeated to document the degree of maximal response.
