About 30% to 70% of lung cancer patients have lung cancer bone metastasis, which is a great concern for lung cancer patients and their families. No doctor can accurately estimate the survival time. A considerable number of patients regard lung cancer as a fatal disease with a very short survival period and are pessimistic and disappointed after learning that they have lung cancer and have no confidence in treatment. In fact, the influence of psychological factors plays an important role in the treatment of lung cancer. Adverse emotions will reduce the immunity of the body and its ability to identify and remove tumor cells. And a good psychological condition can not only prevent the occurrence of tumor, but also make the emerged tumor in a self-limiting state and eventually be eliminated by the body’s own immune function. The care of advanced lung cancer patients is crucial 1. When lung cancer patients have no difficulty in swallowing, they should be free to choose food, and without affecting the treatment, they should eat more protein and carbohydrate-rich food to improve the dietary quality and create good conditions for surgery. If the nutritional status is poor, it is difficult to tolerate the trauma of surgery, slow healing and easy infection after surgery, which is unfavorable to surgery recovery. 2.Elements diet contains various nutrients necessary for human body. When enough calories are supplied, it can supplement protein nutrition and promote the synthesis of muscle protein, and when calories are not supplied enough, branched-chain amino acids can also provide more calories. There are many kinds of elemental meals, when applied, start with low concentration, if orally should pay attention to slow drinking, because the elemental meal is hypertonic liquid, cited too fast easily produce diarrhea and vomiting. 3, post-operative diet allocation: post-operative diet allocation according to the condition. Because the surgery trauma will cause the dysfunction of the digestive system, so in the food selection and supplementation, do not rush. All should eat more fresh vegetables and fruits. Fruits and vegetables are rich in vitamin C, which is a cancer inhibiting substance and can block the generation of cancer cells, and also garlic contains anti-cancer substances. Develop good living and eating habits, regular physical examination, timely diagnosis and treatment. 4.Prevention of decubitus ulcers: The nutritional status of patients with advanced lung cancer is generally poor, sometimes combined with systemic edema, which is very easy to produce decubitus ulcers, and it is difficult to cure because of rapid expansion. It is especially important to prevent the occurrence of decubitus ulcers. Reduce local pressure, change the position on time, and use air rings and soft pillows to cushion vulnerable parts of the body to avoid long-term pressure. 5. Keep the skin clean, especially for patients who are incontinent, keep the bed clean and flat, and apply a baking lamp to the broken skin to keep the area dry. and assist the doctor in resuscitation. 7.Patients with advanced lung cancer often have metastases to different parts of the tumor, which cause different symptoms, and should be observed and given corresponding care. 8.For example, liver or brain metastasis may cause sudden coma, convulsions and blurred vision, so nursing staff should detect and give symptomatic treatment in time. For bone metastases, limb protection should be strengthened. For abdominal metastases, intestinal obstruction often occurs, and patients should be observed for symptoms such as abdominal distension and abdominal pain. 9.Oedema can occur due to malnutrition and low plasma protein, which should be reduced by increasing nutrition and elevating the affected limbs. 10.Psychological care: Patients with advanced lung cancer will have anxiety, fear, sadness and other psychological problems, and often appear to be indifferent and lonely. Therefore, patients in this period are afraid of being indifferent and abandoned, often feel lonely, especially at night, always feel that death is coming, the care of family members will make patients feel safe, comfortable and warm. We should take various measures to alleviate patients’ pain, which is the basis of good psychological care. Thus, it seems that nursing of advanced lung cancer patients plays an irreplaceable role in their treatment and recovery, and good basic nursing of advanced lung cancer patients can effectively improve the quality of life of advanced lung cancer patients and prolong their survival period, which brings great spiritual encouragement to them. In general, how long a patient can live with advanced lung cancer varies depending on the treatment effect and physical function, but as long as the appropriate treatment method is chosen, it can improve the symptoms and prolong the survival period. With the continuous improvement of treatment methods, new treatment methods and drugs are increasingly used in the treatment of advanced lung cancer, and the survival period of patients with advanced lung cancer is significantly higher than before. Patients should not be trapped by the question of how long they can live with advanced lung cancer, nor should they believe in the advertisements that advertise how long a certain drug can make them live. The question of how long a patient can live in the late stage of lung cancer is not necessarily an exact answer for any patient, and it is most important to receive regular treatment as soon as possible.
