Brief Summary:
RATIONALE: Drugs used in chemotherapy 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 (Bv) may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving combination chemotherapy together with bevacizumab is more effective than combination chemotherapy alone in treating colon cancer in adjuvant setting.
PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens with or without bevacizumab to compare how well they work in treating patients who have undergone surgery for high risk stage II or stage III colon cancer.

Detailed Description:
This was an open-label Phase III, multicenter, multinational, randomized, 3-arm study designed to evaluate the efficacy and safety of bevacizumab in combination with either intermittent fluorouracil/leucovorin with oxaliplatin (FOLFOX4) or capecitabine plus oxaliplatin (XELOX) versus FOLFOX4 regimen alone, as adjuvant chemotherapy in colon carcinoma.
The treatment phase consisted of two parts of 24 weeks for a total of 48 weeks. The first part (weeks 1 to 24) consisted of treatment with either FOLFOX4, FOLFOX4 in combination with bevacizumab, or XELOX in combination with bevacizumab. The second part (weeks 25 to 48) consisted of single-agent bevacizumab for patients randomized to either bevacizumab-containing arm, but was only an observation period for patients assigned to the FOLFOX4-alone arm.
Patients were to be followed for recurrence/new occurrence of colorectal cancer and survival. Patients who experienced a confirmed recurrence, occurrence of a new colorectal cancer during therapy, or experienced unacceptable toxicity were to be taken off study treatment but remain in study follow-up. Patients that came off therapy due to a confirmed recurrence/appearance of new colorectal cancer, were to be followed for survival until the end of the study follow-up period. The primary analysis was performed 36 months after the last patient has been randomized. After the primary analysis, patients continue to be followed for survival for at least a further 2 years ie, until all patients have been followed-up for at least 5 years following randomization.
