Yes, I have a suggestion. A friend of mine has a son in the same position. Mets to the omentum, mysentery, etc. Mayo couldn't offer him anything but they did have surgery at Wake Forest and combined that with the heated chemo. I know of another person in the same situation. I would HIGHLY suggest calling Dr. Levine at Wake Forest University. He and his team are world renowned for their surgery and approach.

I would suggest reading these articles and consider calling them. It apparently takes quite a long time to see Dr. Levine but seeing any of his staff is also fine. They all do the procedure together.
Hope this helps.
