What is interventional treatment for liver cancer? Introducing the specific process of interventional treatment for liver cancer

Interventional treatment of liver cancer tumors can use larger drug doses through trans-arterial drug administration, but because the drug administration is precise, the drug causes less damage to other tissues and organs in the body, the drug causes fewer toxic side effects, the body recovers faster, and there are fewer complications from treatment. In addition, embolization therapy can effectively inhibit tumor development and win precious time for surgical treatment.

Interventional therapy refers to a method of diagnosis and treatment through blood vessels, based on imaging and clinical diagnosis results, with the help of catheter guidewires and other therapeutic equipment, under the guidance of medical imaging equipment. Compared with traditional treatment methods, the application of interventional therapy in the treatment of liver tumors causes less trauma to patients, has higher treatment safety, fewer side effects, and more ideal treatment effects.

1. Selective hepatic artery infusion. It refers to the intra-arterial infusion of drugs through a catheter at a dose equal to or less than that of intravenous administration, which can increase the local drug concentration of target cells, prolong the contact time between the drug and cancerous tissue, and reduce the total dose of systemic drugs, thereby achieving the purpose of improving efficacy and reducing side effects. The efficacy of selective hepatic artery infusion of chemotherapy drugs and the effective blood concentration of drugs at the tumor site are positively correlated with the time the drugs are exposed to the tumor.

Second, selective hepatic artery embolization. It refers to the use of special catheters to selectively inject embolic agents into tumor blood vessels and tumor blood supply arteries, blocking the tumor blood supply and destroying the tumor vascular bed, thereby inhibiting the growth of the tumor, which is equivalent to starving the tumor to death. Commonly used embolic agents are gelatin sponge, super-liquid iodized oil and sodium alginate microspheres. In addition to embolization, selective transcatheter arterial chemoembolization can also be performed. Chemotherapy and embolization can be performed simultaneously through the catheter, and the effect is also relatively ideal.

Traditional tumor intervention and treatment methods include radiosurgery, radiotherapy and chemotherapy, as well as traditional Chinese medicine. Compared with traditional methods, interventional therapy has the advantages of minimally invasive, low cost, safety and good efficacy, especially for tumor patients who cannot undergo surgery, the treatment effect is better and the long-term survival rate is higher. Interventional therapy directly administers drugs through arteries, which can be used for large doses of drug treatment, with stronger efficacy and fewer side effects.

In summary, interventional treatment of liver cancer mainly refers to the use of minimally invasive technology to directly administer drugs to tumor lesions through blood vessels for treatment. Compared with traditional treatment methods such as surgery, radiotherapy and chemotherapy, interventional treatment is more precise in drug administration, the drug efficacy reaches the lesions directly, the treatment effect is better, the effective concentration of drugs in tumor tissue is higher, but the side effects on normal tissues are smaller, and its status in tumor treatment is getting higher and higher.
