Interventional therapy can be applied to many malignant tumors. Besides the most common liver cancer, interventional therapy has also achieved better efficacy in the treatment of the following tumors. 1.Gastric cancer perfusion therapy: The main sites of gastric cancer are the less curved side of gastric fundus and gastric sinus. Most of the lymph node metastases of gastric cancer are also distributed along the left gastric artery. Depending on the location of tumor, the left gastric artery, abdominal cavity artery, gastroduodenal artery and common hepatic artery are selected for cannulation and one-time high-dose infusion of anti-cancer drugs, which is effective in reducing lesions, improving surgical resection rate, preventing intraoperative medical spread and preventing liver metastasis. 2.Bronchial artery perfusion chemotherapy for lung cancer: selective bronchial arteriography and intra-arterial chemotherapeutic drug perfusion for lung cancer are also commonly used in clinical practice, among which repeated drug administration is more effective than single drug administration. 3.peritoneal artery perfusion chemotherapy for pancreatic cancer: systemic chemotherapy for pancreatic cancer is not effective. The infusion of chemotherapy drugs through the cavity artery can effectively increase the blood concentration in the tumor site and rapidly reduce the symptoms of abdominal pain, with good effect and low side effects. 4. Intubation chemotherapy for pelvic tumor: super-selective intubation of chemotherapeutic drugs by percutaneous femoral artery puncture in the internal iliac artery is a better treatment method for pelvic confined tumor, which can provide a chance to continue treatment for patients with advanced tumor who cannot tolerate surgery, lose the chance of surgery or other treatments are ineffective.
