How long does a person with cachexia live?
The ASCO guidelines describe the onset of cachexia as weight loss that exceeds 5% over the previous six months or depletion of muscle mass and more than 2% weight loss. Refractory cachexia is characterized by poor performance status, progressive cancer, and a life expectancy of less than three months.
What are the stages of cachexia?
Cancer cachexia is divided into three consecutive clinical stages:10 pre-cachexia, cachexia, and refractory cachexia, though patients may not experience all three stages.
How does cachexia lead to death?
Cachexia is estimated to occur in up to 80% of people with advanced cancer, depending on the cancer type and how well they respond to cancer treatment. And it's thought to directly cause up to 30% of cancer deaths, often because of heart or respiratory failure related to muscle loss.
Can you gain weight if you have cachexia?
Caring for the cachectic patient presents a frustrating and recurring dilemma. Cachexia is defined as ongoing weight loss, often with muscle wasting, associated with a long-standing disease. In cachexia, refeeding often does not induce weight gain.
What is the best treatment for cachexia?
Thalidomide has multiple immunomodulatory and anti-inflammatory properties; its inhibitory effect on TNF-α and IL-6 production may be responsible for its anticachectic activity. Thus, thalidomide has been used for treatment of cachexia associated with acquired immunodeficiency syndrome, tuberculosis, and cancer.
What is the main difference between anorexia and anorexia nervosa?
"Anorexia" describes a simple inability or aversion to eating, whether caused by a medical problem or a mental health issue. "Anorexia nervosa," however, is the name for the clinical eating disorder, the main symptom of which is self-starvation.

What is cachexia in cancer?
Cancer anorexia-cachexia syndrome (CACS) is a common problem in advanced cancer and especially in ovarian cancer. “Cachexia is among the most diebilitating and life-threatening aspects of cancer.” It is associated with anorexia and wasting of muscle tissue and fat, and arises from an interaction of tumor and host cytokine response. There is a weight loss of more than 5% within 6 months. [ 159] Weight loss reduces survival time. Cachexia is increased in the elderly and in children, and in more than 20% it is the main cause of death. With ovarian tumors there are special problems of gastrointestinal obstruction, malabsorption, surgery, chemotherapy, and depression. With simple starvation, there is an increase of appetite, decrease in metabolism, and relative sparing of lean body mass. With cachexia, the appetite is reduced, the metabolic rate is increased, and there is a wasting of lean body mass resulting in reduced tolerance to therapy and increase of surgical complications. [ 159] Sometimes correction of possible reversible factors may bring some relief such as anemia (with erythropoietin), dehydration, infection, pain, and depression. Megestrol acetate and glucocorticoids short term have been used.
What is CACS in medical terms?
CACS is defined as a complex metabolic syndrome associated with an underlying disease that is characterised by loss of weight and muscle mass, with or without the loss of fatty mass, often associated with anorexia, inflammatory processes, insulin resistance and increased tissue protein turnover rates [7].
How does cachexia differ from other types of weight loss?
