[Tumor cachexia--a special entity and therapeutic sequelae].

Cancer cachexia as a syndrome of generalized host tissue wasting results from interactions of tumor, host and tumor-directed treatment. Cancer cachexia may be associated with all terminal cancer stages and is not tumor-specific. Weight loss, functional impairment and deterioration of the quality of life require palliation. A therapeutic algorithm based on therapeutic standards is proposed: appropriate use of parenteral and enteral nutrition, of progesterone analogues and of metoclopramide. Innovative concepts that may enable prophylactic rather than therapeutic interventions are currently under investigation.
