S0408: Capecitabine, Oxaliplatin, and Bevacizumab in Pts Undergoing Surgery for Liver Mets From 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 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 tumor cells by blocking blood flow to the tumor. Giving capecitabine and oxaliplatin together with bevacizumab before and after surgery may be an effective treatment for liver metastases.
PURPOSE: This phase II trial is studying how well giving capecitabine and oxaliplatin together with bevacizumab works in treating patients who are undergoing surgery for liver metastases due to colorectal cancer.
