Abstract:
Cancer cachexia has been listed as a major cause of death in cancer patients. In order to investigate the metabolic effects of the tumor on the host, we have evaluated an experimental model of cancer cachexia in the mouse (MAC16 colon adenocarcinoma), in which weight loss can reach 30-40% of initial weight with a tumor burden of only 2.5%, without a reduction in the intake of either food or water. The weight loss appears not to arise from tumor necrosis factor production, which is associated with a marked reduction in both food and water intake, but may be a result of catabolic factors produced by the tumor and present in the circulation. Both insulin and 3-hydroxybutyrate are effective inhibitors of the tumor catabolic factors in vitro and protect, to some extent, weight loss in vivo. However, whereas 3-hydroxybutyrate was associated with a reduction in tumor weight, insulin caused an enhancement, suggesting that the former may be more appropriate than the latter in the clinical treatment of cancer cachexia.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
