RATIONALE: 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. 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. Chemoembolization kills tumor cells by carrying chemotherapy drugs directly into the tumor and blocking the blood flow to the tumor. Giving bevacizumab together with chemoembolization may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bevacizumab together with chemoembolization works in treating patients with liver cancer that cannot be removed by surgery.
