Malignant stroma is usually irreversible, the treatment of patients with malignant stroma is more difficult, and the condition usually cannot be better recovered and improved through treatment. If a malignant tumor develops to malignant stroma, it is often already in the terminal stage of cancer. As the patient has been tortured by the disease for a long period of time, the growth and reproduction of the tumor cells consume a large amount of nutrients in the body, resulting in a lack of nutrients in the body such as fat, protein and other nutrients, and the atrophy of the muscles and the subcutaneous fat, which has already been unable to achieve a better therapeutic effect, and basically can not be reversed and recovered. For tumor patients with malignant disease, intravenous supplementation of appropriate nutrition should be actively used, and nasal feeding tube can also be chosen to provide nutrition to the patient, to maintain the patient’s body state as much as possible, to minimize the patient’s pain and prolong the patient’s survival time.
