Tank - Back to you for a minute. This week I've been doing some research because a friend has been diagnosed with pancreatic cancer. It occurred to me today that some of this might be helpful to you to (I'm an MD).
Resveratrol - the stuff in red wine that is so good for us, concentrated down into a capsule - is readily available as a supplement (here in the U.S., anyway). There's a lot of research being done about its anti-cancer effects, and here's a study on stomach cancer: http://www.ncbi.nlm.nih.gov/pubmed/11960777
It is safe and well-tolerated, although if you are on coumadin, you may need your coumadin dose adjusted. In pancreatic cancer, it also seems to make cancer cells more sensitive to chemo.
