Good Nutrition Critical to Chemotherapy

• Weight loss has been shown to be a poor prognostic sign in cancer.

• Malnutrition can impair the response to treatment, quality of life, and the immune system.

• It has been estimated that 80% of cancer patients never receive a nutritional

evaluation.

Is there any evidence that malnutrition has a real impact on cancer treatment or on a person's chances of surviving the disease?

• Numerous studies strongly suggest that substantial malnutrition has serious

consequences for cancer patients.

• Malnutrition reduces the

effectiveness of chemotherapy, lowers overall quality of life and

lowers patients' chances of survival.

• The older group was more likely to eat less food than usual (55% vs. 45%), to have a global fat deficit (56% vs. 44%) and to have existing edema (58% vs. 42%).
