Too much nutrition, tumor grows fast? A lot of cancer patients do wrong!
By Chen Yingping, reporter of Yangcheng Evening News
Many patients in our country find that they are in the middle and late stage of cancer, and they will appear emaciation and fatigue. But in the process of treatment, it is common for patients to pay more attention to supplements and less attention to nutrition. Clinical data show that malnutrition will directly affect the prognosis of patients and reduce the survival time. At the special meeting on nutrition and rehabilitation for cancer patients at the first Annual Conference on cancer support and rehabilitation in Suzhou, medical experts urged that nutrition support is very important for cancer treatment and should be persisted throughout. So, how should cancer patients make up for it?
The patient is too thin and anaemia first “take care of”
Data show that 20% to 80% of cancer patients in China will suffer from malnutrition. Cancer treatment, including surgery, radiotherapy and chemotherapy, many people will have nausea, vomiting, diarrhea and other more serious gastrointestinal reactions, patients can not eat hard to absorb and cause malnutrition, resulting in anemia and weight loss. On the other hand, many advanced patients have fatigue and emaciation before treatment, unable to treat.
Professor Yao Qinghua, director of the Department of integrated traditional Chinese and Western medicine of Zhejiang Cancer Hospital, shared a 60 year old patient with advanced gastric cancer who received nutritional support before treatment. The female patient had multiple metastases of lymph node, intestine and stomach, which reduced 8 kg in a month. Before admission, she vomited seriously, couldn’t eat food or even drink water. After the evaluation of nutritionists, was diagnosed as severe malnutrition.
The oncologist and the nutritionist worked out a set of nutrition supplement plan for her, and the nutrition treatment was carried through all the time. Later, the patient’s physical condition improved, and was able to complete a series of treatment such as chemotherapy and resume eating.
The reporter learned from the interview that the successful cases of nutrition intervention treatment similar to those mentioned above are not popular in China at present due to the concept and doctors’ equipment. Only 30% of the patients with malnutrition have received scientific and reasonable nutrition intervention in large hospitals.
Professor Wang Jiejun, chairman of the Expert Committee on cancer support and rehabilitation therapy of the Chinese society of Clinical Oncology, pointed out that the nutritional status of patients with gastric cancer, colorectal cancer and pancreatic cancer is generally worse, which directly affects the survival of patients.
How to “support” correctly?
According to experts, the first step in the nutritional treatment of cancer patients is to carry out nutritional screening, score and grade the nutritional status of the patients; the second step is to develop personalized nutritional supplement programs, including diet, oral nutrition powder, parenteral nutrition drip, etc., which requires close cooperation between the nutritionists and tumor doctors.
Professor Xie Yaochang, from the clinical oncology department of Hong Kong, pointed out that the common dietary and nutritional misconceptions of patients are: the diet should be light or even vegetarian. In fact, cancer patients need a high protein diet. Reducing food intake will lead to insufficient protein absorption and accelerate muscle loss. He suggested that the diet of cancer patients should be high protein, high energy, high fat and low carbohydrate, such as meat, fish, eggs and dairy products.
Common dietary misconceptions of Zhiduo D cancer patients
1. Should cancer patients eat a light diet, mainly fruits and vegetables, and avoid animal products, such as milk or meat?
wrong. Cancer patients should maintain a balanced diet to provide adequate nutrients. Cancer patients need a high protein diet. Meat and milk are rich in high-quality protein. Reducing food intake will lead to insufficient protein absorption and accelerated muscle loss.
2. Cancer patients need low sugar diet to starve cancer cells?
wrong. Low sugar diet will not starve cancer cells, but will increase the chance of malnutrition in cancer patients. Intake of enough calories and protein is the primary goal, in order to maintain a better body to overcome all kinds of discomfort during treatment.
