One in three adults will develop some form of cancer in their lifetime. The incidence of malnutrition in cancer patients ranges from 40 to 80%, and most often presents at the time of diagnosis. Malnutrition is recognized as a poor prognostic indicator and can significantly impact treatment and recovery.
Cancer and its treatment can affect a patient’s nutritional status in a number of ways. Chemotherapy and radiation therapy not only kill cancer cells, but also healthy, normal cells and tissues. Some of the adverse effects associated with these treatment regimes include nausea, vomiting, diarrhea, mucositis (ulcers or sores in the mouth, stomach and intestine), decreased ability to digest food, plus alterations in smell and taste.
Even a 5% loss in body weight can negatively affect a patient’s response to treatment. Proper nutritional intervention has a place in cancer treatment. Among the recorded benefits are improved ability to perform activities of daily life, fewer complications ie, infections, fewer treatment interruptions, better tolerance of treatments and favourable psychological effects, including improved quality of life.
The main objectives of nutritional intervention in cancer patients are to increase energy and nutrient intake in ways acceptable to the patient, to tackle problems which restrict food intake, and to identify when further support measures are needed.
It is highly recommended that all cancer patients undergoing treatment meet with a dietitian who will assess their current nutritional intake and needs. The dietitian will work with the patient to develop a dietary plan aimed at restoring or maintaining good nutritional status.
