17cm tumor protruding towards heart

My Husband is a livern transplant patient of 5 years and now has liver cancer and a small one in lung. The dr siad teh liver tumor is massive and gave him nexavar to start. We are in Dallas and trying to get into MD Anderson for a second opinion. Anyway, just go on here looking for information on Nexavar a success statistics on it. The Dr. didn't give us a time ot anything. She said she didn't know but is treating it as stage IV.
