RATIONALE: Drugs used in chemotherapy, such as pentostatin and 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 and bevacizumab, 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. It is not yet known whether giving pentostatin and cyclophosphamide together with rituximab is more effective with or without bevacizumab in treating patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.
PURPOSE: This randomized phase II trial is studying the side effects of giving pentostatin and cyclophosphamide together with rituximab with or without bevacizumab and to see how well it works in treating patients with B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.

Arms | Assigned Interventions |

Arm I: Experimental
Patients receive bevacizumab IV over 30-90 minutes on day 1 of courses 1-5 and on days 1, 22, and 43 of course 6; rituximab IV over 2-4 hours on days 2 and 3 of course 1 and on day 1 of courses 2-6; and pentostatin IV over 30 minutes and cyclophosphamide IV over 30 minutes on day 2 of course 1 and on day 1 of courses 2-6. Patients also receive pegfilgrastim subcutaneously (SC) on day 3 of course 1 and on day 2 of courses 2-6. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.

OBJECTIVES:
Primary
Secondary
OUTLINE: Patients are stratified according to Rai risk group (high [Rai stage III or IV] vs low [Rai stage 0] or intermediate [Rai stage I or II]) and FISH prognosis group (favorable [normal, +12, 13q-, or other] vs unfavorable [17p- or 11q-]). Patients are randomized to 1 of 2 treatment arms.
NOTE: *Course 6 is 56 days in duration
NOTE: *Course 6 is 56 days in duration
Patients undergo blood sample collection and bone marrow biopsy/aspiration periodically for translational research studies. Samples are analyzed by flow cytometry for assessment of minimal residual disease. Molecular prognostic markers (including CD38, ZAP-70, IgVH gene mutation status, and cytogenetic abnormalities by FISH), Tcl-1 and CD49d protein expression, and immunoglobulin heavy chain D and J family gene usage are also analyzed. Plasma samples are stored for future studies evaluating levels of VEGF, bFGF, and thrombospondin by ELISA.
After completion of study therapy, patients are followed periodically for up to 5 years.
