The maximum number of chemotherapy treatments for advanced gastric cancer is decided according to the condition and patient’s physical quality. 3-4 times of chemotherapy treatments for advanced gastric cancer are given, and the need to continue chemotherapy is decided according to the post-operative recovery, and 1-2 times can be added for those who have better tolerance or are more sensitive to chemotherapy drugs. For advanced gastric cancer, if the gastrointestinal reaction is serious after 1-2 times of chemotherapy or there is obvious bone marrow suppression, multiple times of chemotherapy is not advocated for advanced gastric cancer, and symptomatic supportive treatment should be the main treatment direction to reduce pain or improve the quality of survival of advanced gastric cancer, and extra-gastrointestinal nutritional support can be given to reduce pain.
