Intermediate gastrectomy chemotherapy for pancreatic cancer is not necessarily curable, and its five-year survival rate is about 40%. Cardia cancer is a common malignant tumor, which can be metastasized through blood, lymph nodes and plantation, and the common symptoms are mainly eating disorder, obstruction and abdominal pain. When the disease develops to the middle stage, it means that the tumor cells have infiltrated or metastasized to lymph nodes, and it is necessary to control the spread and metastasis of the cancer cells through the comprehensive treatment of gastric resection surgery, preoperative chemotherapy or postoperative radiotherapy. Through standardized treatment, only the progression of the disease can be controlled, which prolongs the life span of the patient. However, if the disease has not yet metastasized, some patients can be cured through surgical treatment.
