Although I've not heard of it, I too am a Stage IV colon cancer survivor. I was diagnosed in July of '04.
Although I didn't use the above, I did use HAI Therapy.
I had colon cancer with mets to the liver.
I used Irinotecan and used an HAI pump that put FUDR directly into my liver. It caused no side effects. The HAI caused no side effects
Everyone is different, and works for them is different.

I was initially told that I could die at any moment, but had 18 months to live with surgery. I am still here, with no signs of cancer.
You may want to try the colon site, since the diagnosis is colon cancer with mets to the liver.
Good luck.
