Omega 3 fatty Acids to fight/prevent muscle & weight Loss due to chemo. (?).

I recently read an article (http// was said to have been published in CANCER a peer-reviewed journal of the American Cancer Society (dated: 2/28/2011), that stated that fish oil (omega-3 fatty acids), may help combat cancer related malnutrition (loss of weight and muscle mass). I am curious as to if anyone else is aware of this discovery; Or, may have tried it themselves (?).
