Anorexia and cachexia

(PSYCHIATRIC TIMES) - Many patients with advanced cancer undergo a wasting syndrome associated with cancer anorexia/cachexia and asthenia.

Patients who exhibit such symptoms generally have a short survival, respond poorly to cytotoxic agents, and suffer from increased toxicity from these agents. In addition, cancer… Continue
