Cancer patients often experience a profound loss of appetite (anorexia), especially in the last weeks of life, as well as a deterioration and wasting of body tissue (cachexia). There is clear evidence that cancer patients have undergone metabolic changes in their physiological responses to food. The metabolic changes with cachexia seem to be mediated by a variety of molecules in the body (including proinflammatory cytokines, neuroendocrine hormones, neurotransmitters, eicosanoids, and tumor-related substances) (produced by the tumor itself and by the body in response to the tumor; Barber et al., 2000). Cachexia is the immediate cause of nearly one-third of cancer deaths (Argiles and Lopez-Soriano, 1999).
Pharmacologic agents commonly used to treat cachexia include corticosteroids and progestational drugs (Gagnon and Bruera, 1998). Eight randomized, double-blind, placebo-controlled studies have confirmed that progestational drugs can increase appetite, food intake, and energy level. Additionally, in many patients, these drugs increase weight, and may also have an effect on nausea and vomiting (Body, 1999). Drugs that lessen the process of skeletal muscle protein catabolism that occurs in cachexia pa
