Cardia cancer is currently treated mainly by traditional treatments such as surgery and radiotherapy, which should be considered first. There are many patients who have undergone interventional treatment for cardia cancer here, mainly in the following cases: a. Patients who cannot undergo surgery or are unwilling to undergo surgery and radiotherapy. Patients who cannot undergo surgery or are unwilling to undergo surgery and radiotherapy because of their physique, age, fear of trauma, difficulty of invading large blood vessels with complex tumor structure, excessive risk or metastasis, etc. Patients with advanced disease, patients with persistent bleeding after radiotherapy, or acute hemorrhage, do interventional embolization to stop bleeding for the purpose of hemostasis. Third, to improve feeding for the purpose of: placement of esophageal stents or percutaneous gastrostomy leak and gastric tube. The stent carrying radioactive particles can improve feeding and have therapeutic effect on tumor at the same time, which has been clinically applied and the effect is more ideal. It has been clinically applied and has better effect, but the cost is higher. Arterial perfusion and embolization is a kind of local palliative treatment which is more effective than systemic chemotherapy and has less side effects. After interventional treatment, radiotherapy can be done to further improve the therapeutic effect. V. Postoperative anastomotic stenosis, esophageal-tracheal leak and mediastinal leak of esophageal cancer are also indications for intervention. Sixth, embolization to stop bleeding and esophageal stent can be done once, while perfusion needs to be done repeatedly for 2-6 times with an interval of 4-8 weeks each time. The cost of each time is about 5000-7000.
