  • About disease-related malnutrition

    Malnutrition or malnourishment is a condition that occurs
    if the body does not get the right amount of nutrients to maintain its health.
    When this is due to the effects of a disease or illness we call it
    disease-related malnutrition.

What is cancer-related malnutrition?

Disease-related malnutrition is present in a wide range of diseases. The problem is known worldwide, affecting about 20 million patients with the cost of 120 billion Euros in the European Union countries.1 Cancer-related malnutrition is the type of malnutrition triggered by the malignant disease. Cachexia is a complex metabolic syndrome with underlying illness and characterized by loss of muscle with or without loss of fat mass.2 Cancer cachexia is defined as general physical wasting and malnutrition associated with cancer. More than 30% of cancer patients die due to cachexia, while more than 50% die with cachexia being present.

Weight loss / cachexia is a major distress for cancer patients, partly because muscle wasting makes the disease visible. Weight loss is negatively correlated to treatment toxicities, response rate, quality of life and overall survival in cancer patients.3-6 Malnutrition is also an independent predictive factor of early discontinuation of anticancer treatment, which in turn is correlated to poorer results in curative or adjuvant setting.7

What are the causes of cancer-related malnutrition?

By population prevalence, cancer-related cachexia is one of the most frequent cachexia subtypes.8 Weight loss seen in cancer patients is understood to be driven in a varying degree by low food intake. Low food intake may be the result of a wide variety of symptoms directly or indirectly limiting oral intake. Direct limiting factors among others are anorexia, swallowing difficulties, alterations in taste and smell, while indirect limiting factors include pain and fatigue. A variety of metabolic and endocrine changes, and activation of catabolic pathways account for some of the weight loss, that is typically greater than could be expected for the level of food intake.9 Malnutrition and cachexia are common findings in cancer patients, and they become more evident with tumor growth and metastases. The mechanisms by which they are sustained involve damage caused by the primary tumor or by anticancer therapies (surgery, chemotherapy, radiotherapy). Meal-related neural or hormonal signals and humoral signals related to body fat or energy storage and the interaction of these signals with the brain play a pathogenetic role10

Anti-tumor therapies such as surgery, chemotherapy and radiotherapy also have an impact on the nutritional status. Surgery itself can reduce food consumption and increase nutritional requirements. Surgical interventions in the oral cavity, to the tongue, salivary glands, and olfactory nerve lead to loss of taste and smell, which in turn cause reduced food intake and thus nutritional decline. Chemotherapy can affect nutrient uptake and cause metabolic abnormalities, such as hyperglycemia, hypercalcemia, and micronutrient deficiency. Nutritional deficits have specific adverse effects on immune competence. When this is combined with immunocompromised state due to cytotoxic agents, the effect is often doubled. Radiation therapy to the head and neck is associated with anorexia, esophagitis, dryness of the mouth, nausea, vomiting, swallowing difficulties, sore throat, and alterations in taste and smell, all of which can significantly reduce food intake and negatively impact nutritional status. Irradiation of the abdomen or pelvic area may cause acute diarrhea, anorexia, nausea, vomiting, abdominal pain, enteritis and colitis, leading to nutritional deficits.11

What are the consequences of cancer-related malnutrition?

Why is it important to be well-nourished?

Getting the right amount of nutrients is crucial for preventing weight loss and muscle wasting which helps keep up strength, overcome weakness and tiredness. It also helps keep the immune system healthy in order to avoid complications, infections and, ultimately, to recover more quickly.

Nutritional support, addressing the specific needs of cancer patients, is required to help improve prognosis, and reduce the consequences of cancer-related nutritional decline.

How can we help?

The main source of nutrients is normally food. However, for patients suffering from cancer-related malnutrition, a healthy diet is often not enough. Since the nutritional demand is increased but appetite is reduced, patients need nutritional supplements that contain high energy in low volume, so even a little quantity significantly boosts the nutritional intake. Specially formulated nutritional products are available for patients to stay well-nourished and fight disease more effectively. They come in all tastes and formats, catering for everyone’s needs.

Medifood’s innovative nutritional product is highly effective due to its beneficial features. Its high energy and protein contents are able to attenuate the deterioration of the nutritional status, to improve weight, to decrease the rate of complications, and to influence the modulators of the catabolic response in cancer patients with malnutrition and cachexia. Since most malignant cells are not able to metabolize significant amount of fats and they use carbohydrates as the main source of energy13, the product with its low carbohydrate content may have an indirect beneficial effect on tumor cell proliferation, and enhance the efficacy of the primary anti-tumor therapy by ameliorating the nutritional status of cancer patients. Due to its high content of ω-3 fatty acids, the product t is able to modulate the level of inflammation and reduce the associated tissue wasting.
