Tumor therapy and drug intervention options 1. Seldinger technique using conventional interventional therapy
Optional femoral artery puncture site, axillary artery, pots artery. According to the lesion may be. As a relatively superficial femoral artery, catheterization convenient, high success rate, complications, very little reliable and safe operation. Currently the most commonly used femoral artery. The specific method is: first, the skin puncture site disinfection, concurrent anesthesia, the femoral pulse in the upper edge, tip to do with the 2-5mm surgical skin incision, was 40 -50 angle into the femoral artery. If the needle appears along the longitudinal axis of the same femoral artery pulse, puncture proof of success. At this point, after pulling the needle core, we can see the end of injection needle arterial blood, immediately inside the guide wire into the vessel, and finally exit the guide wire. Full operation should be carried out under X-ray monitoring.
Cancer intervention and drug therapy selection 2. Drug choice
Commonly used anti-cancer drug infusion and single dose of the drug: MMC10-20mg ,5-F1J 1000-1500mg, DDP50-l00mg, ADM40-60mg, MTX30-50mg, BLM10-40mg. At present, many with high-dose combination therapy, combination therapy is generally based on the following principles: Each individual application of effective chemotherapeutic agents; mechanism of various chemotherapeutic drugs with each other; under the patient so that each chemotherapy drugs have reached the maximum tolerated dose ; toxic effects of selected drugs do not stack; to select a intravenous drug effective chemotherapy regimens.
Cancer intervention and drug therapy options 3. Embolic agent choice of embolic agents used clinically are proximal embolization of gelatin sponges, and shy parking. The former refers to 3-5mm in diameter the size of embolization of blood vessels, which is commonly used in the embolization is less than 3-5mm size of the blood vessels.
Cancer intervention and drug therapy options 4. Interventional therapy indications and contraindications
(1) Indications for organ-specific late stage cancer patients; tumor recurrence or metastasis; mainly used for primary liver cancer and liver metastasis of gastrointestinal cancer after radical operation can also be used for inoperable head and neck cancer. Breast cancer, lung cancer or lung metastases, and limbs, cancer, pancreatic cancer and esophageal cancer , etc. are also be explored.
(2) contraindications serious liver and kidney dysfunction, systemic extensive metastasis, patients can not cooperate.
