Capecitabine, Oxaliplatin, and Bevacizumab in Treating Patients With Metastatic or Recurrent Colorectal Cancer

RATIONALE: Drugs used in chemotherapy, such as capecitabine, and oxaliplatin, 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 find tumor cells and kill them or carry tumor-killing substances to them. Others interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving capecitabine and oxaliplatin together with bevacizumab may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with bevacizumab works in treating patients with metastatic or recurrent colorectal cancer.
