Arterial chemotherapy usually refers to arterial infusion chemotherapy. It is not possible to determine which is better, arterial infusion chemotherapy or intravenous chemotherapy, as each patient’s physical condition, the severity of the disease, and the treatment plan adopted are different. Arterial infusion chemotherapy is a minimally invasive, safe and less painful tumor treatment method. Under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body for local treatment of tumors. It does not need to cut the human body tissues during the operation, which is more suitable for the malignant tumors of liver, lung, pelvis and soft tissues that have lost the chance of operation or are not easy to be operated. Intravenous chemotherapy refers to the use of some cytotoxic chemotherapeutic drugs for intravenous infusion, which belongs to systemic drug therapy and can control the spread and metastasis of cancer cells.
