I think I have read that fish oil based lipid infusions help stem weight loss in cancer.
Fish oil based infusion are also being tried with low dose cox inhibitors as a treatment in varous cancer types see Geek diet post link below.
The article on the lung cancer patient is also thought provoking.
Dietary change should be discussed with you medical advisors. If the lipid infusion was of any interest you could always print out the trials and take them along.
I hope things improve.
You are being very brave about it all.
