After the resection of gastric cancer, the cancer cells have spread and produced distant metastasis, so it is not very meaningful to operate again. At this time, comprehensive treatments such as radiotherapy, Chinese herbal medicine and biological immunotherapy can be taken to slow down the spread of cancer cells, further improve the patient’s survival quality and prolong the patient’s survival period. The patient’s mental state and nutritional status should also be considered. If the nutritional status is poor, additional nutritional supplements are needed to strengthen the patient’s body resistance. If the patient’s physical condition is particularly poor and may not be able to tolerate radiotherapy, chemotherapy or targeted therapy, then only appropriate nutritional support can be given.
