 RATIONALE: Drugs used in chemotherapy, such as cisplatin and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Infusing chemotherapy directly into the liver and giving it together with sorafenib may kill more tumor cells.
