How does cancer cachexia indicate the prognosis of a cancer patient?

·

How does cachexia occur in cancer patients?

Although the weight loss brought on by starvation is mainly from adipose tissue stores, the weight loss of cancer cachexia is caused by loss of both skeletal muscle and adipose tissue mass[68]. In patients with cachexia there is an increase in muscle protein catabolism leading to a net loss of muscle mass.

What is cancer cachexia?

Cancer cachexia is a wasting syndrome characterized by weight loss, anorexia, asthenia and anemia. The pathogenicity of this syndrome is multifactorial, due to a complex interaction of tumor and host factors. The signs and symptoms of cachexia are considered as the prognostic parameters in cancer patients.

Does cachexia indicate end of life?

Cachexia, defined by specific weight loss criteria, has a devastating physical and psychological effect on patients and caregivers. It results in a loss of muscle mass, altered body image, and associated decrease in physical functional level; it also often indicates the end of life.

How does cachexia progress?

The precachectic stage is characterized by early clinical and metabolic signs, such as weight loss (less than 5%), anorexia, and impaired glucose tolerance. The progression to cachexia depends upon multiple factors such as systemic inflammation, cancer type and stage, low food intake, and response to treatment.

How long can you live with cancer cachexia?

Cachexia (score from 5-8): Weight loss is greater than 5% and other symptoms or conditions associated with cachexia are present. Refractory Cachexia (score 9-12): This usually includes people who are no longer responding to cancer treatments, have a low-performance score, and have a life expectancy of less than 3

Can you recover from cancer cachexia?

Cachexia is very different to general weight loss. Doctors can’t reverse it fully despite you being able to eat.

Can cancer cachexia be reversed?

A defining feature of cancer cachexia is that it cannot be fully reversed by conventional nutritional support. Cancer cachexia, indeed, is different from simple starvation since, conceptually, both inflammation and metabolic abnormalities may alter the anabolic response of the skeletal muscle after meal ingestion.

Can cachexia be cured?

There is no specific treatment or way to reverse cachexia. The goal of treatment is to improve symptoms and quality of life. Current therapy for cachexia includes: appetite stimulants such as megestrol acetate (Megace)

Why do people lose appetite at end of life?

This could be because they find the effort of eating or drinking to be too much. But it may also be because they have little or no need or desire for food or drink.

What is the mortality rate of cachexia?

Up to 80% of advanced cancer patients will experience cachexia in their disease trajectory (1,2). It is known that cancer cachexia (CC) has a negative effect on function, treatment tolerance and overall mortality, with cachexia being the cause of death in 30% of cancer patients (3).

They find it difficult to perform regular daily activities [18], and experience a significant symptom burden [19, 20]. Patients with cancer cachexia have significant decrease in physical function [21, 22], with low grip strength, and shorter walking distance even when controlling for muscle wasting [23, 24].
