Describe the metabolic changes associated with cancer that contribute to weight loss and nutrient depletion
Cytokines, released by both tumor cells and immune cells, induce an inflammatory and catabolic state. Cancer patients exhibit an increased rate of protein turnover, but reduced muscle protein synthesis. Muscle contributes amino acids for gluconeogenesis (glucose production), further depleting the body's supply of protein. Triglyceride breakdown increases, elevating serum lipids. Many patients develop insulin resistance. These metabolic abnormalities help to explain why people with cancer fail to regain lean tissue or maintain healthy body weights even when they are consuming adequate energy and nutrients.
