Good therapeutic effect: According to the principle of pharmacokinetics, after the drug is injected intravenously (intravenous chemotherapy), when the drug reaches the target organ through a long route, a considerable amount of the drug has already been combined with plasma proteins, which reduces the amount of biologically active free drug, thus reducing the efficacy of the drug. The arterial target vessel drug delivery (interventional chemotherapy), the pathway is short and close to the target organ when the drug protein binding rate is much lower than that of intravenous drug delivery, the drug potency can be increased by 2-22 times, and the efficacy is 4-10 times. Side effects are significantly lower than systemic chemotherapy. Indications of interventional chemotherapy: local chemotherapy can be used for almost all parts of the body with middle and advanced malignant tumors, and for malignant tumors detected at an early stage, the use of “sandwich” treatment (i.e., interventional-surgical-interventional) can significantly reduce the rate of postoperative recurrence. Contraindications to interventional chemotherapy: generally there is no absolute contraindication, but caution should be taken in the following cases: (1) those with serious bleeding tendency; (2) those with serious damage to the function of heart, brain, kidney and other important organs. The blood supply of tumor is very rich, in addition to interventional infusion of chemotherapeutic drugs for adequate killing, the nutritional source of tumor should be cut off as far as possible. Generally speaking, interventional embolization is feasible for the double blood-supplying organs and the parts with rich collateral circulation, such as bronchial artery embolization of lung cancer, hepatic artery embolization of hepatocellular carcinoma, and bilateral internal iliac artery embolization of pelvic tumors, etc. Tumor tissues are necrotic due to ischemia and hypoxia after embolization. Commonly used embolic agents include gelatin sponge, iodized oil, PVA particles, etc.. Traditional Chinese medicine can be used for different periods of interventional therapy, according to the individual treatment, or to support the correctness and lowering the rebelliousness to stop vomiting, or to cultivate the vitality and strengthen the foundation, or to reduce the toxicity and side effects of chemotherapeutic drugs, to enhance the therapeutic efficacy, and to prevent the resistance to the drugs.
