Tumor patients complicated with malnutrition
Malnutrition is one of the common complications of patients with malignant tumors, gastric cancer, the incidence of malnutrition in patients with colorectal cancer and pancreatic cancer can be as high as 70%~80%. In the course of treatment of cancer, stress due to surgery, radiotherapy, chemotherapy treatment, such as the implementation of the increase in patients with digestive tract reaction such as anorexia, increased incidence of malnutrition. In addition, the tumor itself caused by the organism increases in energy consumption and inflammation, also contributed significant cause of malnutrition in patients with cancer. Different from the common weight loss due to hunger, body composition changes in cancer patients with malnutrition is not only a significant fat group lost, there are a lot of muscles and somatic cell loss, accompanied by intracellular fluid, extracellular fluid, protein groups, multiple body such as bone and mineral composition of different levels of consumption. Immunity of patients with malnutrition can cause decreased, accelerate the growth of tumors and can lead to a series of complications. A considerable portion cannot accept or adhere due to malnutrition in patients with radiotherapy and chemotherapy.
Malnutrition affecting cancer therapy
Diet nutrition in cancer patients has been troubled by problems of the patients ' families, many cancer patients often have "more nutrition-rich, cancer cells grow faster" idea. Currently in the clinical treatment of cancer, still common neglect the importance of nutritional support, many in the case of hunger and malnutrition in patients with cancer, repeated many times for chemotherapy, radiotherapy or surgery. Due to malnutrition, reduce plasma protein levels, body to the chemotherapy drug absorption, distribution, metabolism and excretion are obstacles significantly affect plasma dynamics of chemotherapy drugs, lead to increased side effects of chemotherapy drugs, body decline in tolerance, that cancer treatment effects greatly reduced.
Nutritional support ≠ nutrient intake
Nutritional support is through the specific proportion of the supply of nutrients, reach slowed tumor growth process, enhance the effect of tumor treatment purposes. For example, to patients with malignant tumor of fat for energy as the main carbohydrate supplement nutritional support, to improve the nutritional status of patients with, but does not stimulate tumor growth. Studies show that is the need for proper nutrition in the treatment of patients with tumors, because different metabolism of tumor cells and normal cells of the body metabolism, based on the metabolic characteristics of tumor cells to adjust the composition of the nutritional components, makes them is not conducive to tumor growth and give the body enough nutrients, so as to achieve better treatment results. Nutritional support in cancer patients are different from general nutrition, medical doctors and the attention should, by professional doctors according to the specific situation of patients with special nutrition and nutritional support of specific programmes.
Nutritional therapy now is no longer a means of treatment in the past, has gradually become an important means of clinical treatment and gradually for the majority of doctors and patients. See November 4, 2008 edition of the family health report of the original medical guide
