With the prolongation of liver cancer radiotherapy and the accumulation of radiotherapy dose, liver cancer patients will experience various stomach discomforts, such as loss of appetite in mild cases and nausea and vomiting in severe cases. Therefore, before liver cancer radiotherapy, patients should eat as little as possible, and after radiotherapy, they should supplement food, so as to facilitate nutrient absorption. If the stomach discomfort is more serious, metoclopramide (Gastrofluan) or vitamin B6 can be used for symptomatic treatment. During the whole course of hepatocellular carcinoma radiotherapy, one must eat more meals and less food, and consume foods with high protein, low salt and low fat in order to minimize gastrointestinal discomfort. Generally speaking, for inoperable liver cancer, the combination of radiation therapy and interventional embolization can significantly improve the survival of patients. For patients with liver cancer with lymph node metastasis, adrenal metastasis, and inoperable intrahepatic cholangiocarcinoma, radiotherapy can prolong their survival. The treatment of hepatocellular carcinoma can also be carried out with Chinese traditional medicine Hibiscus pill. The side effects of radiotherapy can be treated with Chinese traditional medicine Nourishing Yin and Generating Blood combination to reduce symptoms and enhance its therapeutic effect, so that patients can obtain better survival and life quality.
