My husband has intraheptic with about the same mass. He received approval for the treatment by AETNA and had half the treatment done two weeks ago at the University of Colorado Hospital in Denver Colorado. You might contact UCH Interventional Radiology at 303-372-6130 to see how they got it approved, it was approved very quickly. I can't tell you yet if it has helped or not, I can tell you it made my husband very sick for the first two weeks, and he's still unable to eat as he did before and definately is very weak and fatigued but they tell you that will happen. I'll let you know how he progresses, at first blush I almost wish he hadn't had the treatment because he suffered a lot with it, but if it ends up in the long run making him feel better then I guess it was worth it.
