If the tumor can be removed, you will receive 1 additional cycle of oxaliplatin, leucovorin, and 5-FU (no bevacizumab) at the same doses before you go on to have the surgery. Your surgery will be scheduled 8-12 weeks after the completion of chemotherapy. The surgeon will explain the surgery and any risks. During liver tumor surgery, normal tissue around the edges of the tumor will be collected as part of routine care. You will be asked to sign a separate consent form for the surgery. Additional routine blood tests (about 2 tablespoons) and a PET scan will be done before surgery.
