Interventional tumor treatment follows the principles of general malignant tumor treatment, and has been widely used in clinical practice with its characteristics of minimally invasive, rapid effect and repeatability. A large number of clinical data show that interventional tumor treatment can significantly improve the quality of survival, reduce pain and prolong the survival period of patients. The main treatment is trans-femoral chemoembolization, combined with incisive intra-tumor drug injection or trans-arterial chemoinfusion, which can substantially increase the local drug concentration and block the tumor blood supply to achieve good therapeutic effect. Interventional therapy is a new interdisciplinary and cross-disciplinary treatment combining radiological technology, surgical method and internal medicine, which often selects the patient’s femoral artery to make a small incision, adopts femoral artery puncture technique, and under the surveillance of X-ray, uses a catheter to reach the lesion with a counter-current, injects chemotherapeutic drugs into the lesion, and some can also use embolic agent to embolize the tumor blood supply artery, which can rapidly inactivate the tumor cells. The efficiency is significantly higher than that of systemic chemotherapy. Interventional therapy can increase the local concentration of drugs in the lesion, which is 100-400 times higher than that of systemic drugs, and the effect time is long-lasting, while the toxic side effects on the whole body are significantly reduced compared with systemic drugs. After clinical observation, we found that no patient delayed the next course of treatment due to severe bone marrow suppression after interventional therapy.
