Anti-cancer treatment on nutritional status, cancer treatment must affect people's nutrition, whether the body damage caused by surgery or by chemotherapy or radiation generated by cellular and molecular damage.
Surgery, especially gastrointestinal subtotal, can cause malabsorption of nutrients; gastrectomy, small bowel resection surgery can cause dumping syndrome, respectively, blind mixed syndrome; esophagus, stomach resection due to anastomotic stenosis. Gastric cancer surgery in patients with metabolic response directly after surgery in patients with benign disease similar to, such as nitrogen loss and energy needs increase. In addition to the general reaction to trauma, the oral pharynx and gastrointestinal surgery may be different according to the surgical site has special nutritional problems.
Anti-cancer treatment on nutritional status of chemical treatment can seriously affect the nutritional status of patients, nutrition and appetite inevitably cause damage. Effect may be direct (interference in patients with cellular metabolism or DNA synthesis and cell replication) or indirect (due to nausea, vomiting, taste changes and food aversion.) Most drugs will stimulate the chemoreceptor trigger the hospital, resulting in nausea and vomiting. Gastrointestinal mucosa is particularly vulnerable to the rapid conversion of chemical substances to the injury, resulting in stomatitis, ulcers, absorption capacity decreased. These results in turn, caused by intake and decreased absorption of nutrients and malnutrition led to increased cancer patients. Bone marrow is another organ with high cell transformation, clinical manifestations of anemia, leukopenia and thrombocytopenia.
Radiotherapy effects on the gastrointestinal tract of patients with back support can affect the state. The severity of injury and radiation dose and irradiated tissue volume. The role of radiation therapy are divided into early and late. Early effect is transient and manifested as diarrhea, bleeding, nausea, vomiting, weight loss, mucositis, dry mouth, taste change and loss of appetite and so on. Late effects include intestinal stenosis, mournful pipes and malabsorption.
Anti-cancer treatment on nutritional status, however, the above situation does not explain some of the early or towel on the patient's loss of appetite and weight loss, because the vast majority of patients at this time the tumor has not specified symptoms and signs of money, but also did not receive anti-tumor treatment. Moreover, there are many cancer patients, there has been no above-mentioned factors, the impact of these factors or elbow is not obvious, but also malnutrition and even cachexia. This shows that the occurrence of cachexia must have its deeper causes.
