The average survival period of early gastric cancer patients after chemotherapy is about one year, which is only for patients with local lymph node metastasis and who need adjuvant chemotherapy as determined by pathological type and pathological analysis. Patients should also be reviewed regularly after chemotherapy, especially for local recurrence of the anastomosis. If there is recurrence, chemotherapy should be used again to control the development of gastric cancer. For patients without high-risk factors, adjuvant chemotherapy is not needed after surgery, and only regular review is required. As long as patients pay attention to daily care, such as eating less and more meals, light diet, etc., they can survive for a long time as normal people without special circumstances. It can be seen that the survival period of early gastric cancer patients after chemotherapy cannot be generalized, and it has a certain relationship with the specific condition, treatment method, postoperative care and personal constitution of patients.
