Brief summary
RATIONALE: Drugs used in chemotherapy, such as irinotecan, floxuridine, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of colorectal cancer by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with bevacizumab works in treating patients with stage IV colorectal cancer.
Detailed description
For the purpose of this study treatment cycle consist of six weeks, 2 weeks of consecutive treatment followed by 1 week of rest and 2 weeks of treatment followed by one week of rest. Treatment will be administered weekly, 4 out 6 weeks, on days 1, 8, 22 and 29 according to the schedule. There will be no treatment delivered on weeks 3 & 6 (Days 15 and 36). Disease will be evaluated by CT scan at the completion of every two cycles. Patients with complete response (CR), or partial response (PR), will be evaluated for possible surgical resection. Patients who become operable will continue to be evaluated for survival and disease relapse. Patients with stable disease (SD), and those with less than pCR after surgery should continue chemotherapy until radiographic evidence of tumor progression is identified or unacceptable side effects.

Patients must have a bilirubin of ≤ 1.5 mg/dl and an SGOT of ≤ three times normal for patients with no liver disease, and ≤ five times normal for those with liver metastases. 11. Patients must be informed of the investigational nature of the study and give written informed consent. 12.

Exclusion criteria
1. Patients who have had prior chemotherapy or radiation therapy for their colorectal cancer, with exception of adjuvant chemo/radiation therapy. 2. Patients receiving concomitant radiation, hormonal therapy, chemotherapy, or immunotherapy. 3. Patients receiving any investigational drug within 30 days prior to start of this study. 4. Patients with serious underlying medical illnesses (including Congestive Heart Failure New York Heart Association Functional Classification 2-4) or active infection. 5. Patients with central nervous system metastasis must have completed radiation prior to entry into this protocol. 6. Patients with psychiatric conditions or associated conditions which would make participating in this study dangerous to their health. 7. Patients with uncontrolled hypertension.
