Effects of Chemotherapy and Nutritional Intervention on Gut Function and Metabolism in Cancer
For the cancer subjects, the study involves 1 test day (approx. 8 hours) before
chemotherapy, an approximately 12-week intervention at home starting the first day of
chemotherapy, and one test day after this intervention. A common treatment plan for the
platinum-based chemo is four doses with 3 week intervals and a clinical evaluation after
these 12 weeks. Cancer subjects will be randomly assigned to receiver either fish oil or a
placebo and protein or a placebo and will take these supplements daily throughout those 12
weeks.
For the healthy subjects, the study will involve one test day (approx. 8 hours)
On these test days, the response to a protein meal will be examined and subjects will
receive a mixture of amino acids which are a little bit heavier than normal, called stable
isotopes. Subjects will also ingest a sugar drink to assess gut permeability. In total,
approximate 120 ml of blood will be drawn on each test day to assess outcome measures. The
investigators' will also collect urine over these 8 hours, and cancer subjects are asked to
collect a fecal sample the day before the test day.

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Supportive Care
Net whole-body protein synthesis
The acute change in whole-body protein synthesis rate before and after intake of meal is determined on the first test day for the healthy control group and the cancer group. Secondly, the cancer patients in all 3 intervention arms are also measured after 12 weeks of intervention to examine the effects of fish oil and protein supplementation during chemotherapy on this outcome measure.
Acutely before and after 4 hours of feeding and the change after 12 weeks of supplementation
