The treatment method and prognosis of poorly differentiated gastric cancer are closely related to the stage. Generally speaking, the tumor can be radically resected by surgery in the relatively early stage, and after the surgery, regular adjuvant radiotherapy can be used to control and completely kill the remaining tumor cells, and part of the population can reach the state of clinical cure, and it is possible to survive for 20 years, and the patients can continue to survive for a long time after that.
