What is interventional treatment for liver cancer? Detailed description of interventional treatment for liver cancer

What is interventional treatment for liver cancer? Interventional treatment is one of the more effective treatments for early liver cancer. Below we will further answer this question for you.

The most commonly used technique for interventional treatment of liver cancer is hepatic arterial chemoembolization, which involves inserting a catheter into the hepatic artery via arterial puncture, and then super-selectively inserting a catheter into the tumor's blood supply artery to inject chemotherapy drugs and iodized oil chemotherapy emulsion, thereby performing local high-concentration chemotherapy on the tumor and embolizing the tumor's nourishing blood vessels, eliminating the tumor's blood supply, and achieving the dual effects of "killing the tumor with drugs + starving it to death," according to the study.

For small hepatocellular carcinomas with a diameter of less than 5 cm, microcatheter technology is used to super-selectively cannulate the hepatic segmental or subsegmental arteries, and a large amount of iodized oil chemotherapy drug emulsion is injected under pressure to completely fill the terminal arterioles and venules of the tumor, so as to achieve the purpose of medical hepatic segment resection. If TACE is combined with local radiofrequency ablation or microwave therapy, the therapeutic effect can be similar to that of surgical resection, and it is superior to surgical treatment in terms of safety, recurrence rate, repeatability, complication rate and indications.

For advanced liver cancer with large or numerous tumors, TACE is the preferred non-surgical treatment method, which can effectively control the local growth rate of the tumor, significantly relieve clinical symptoms such as abdominal pain, and improve the patient's quality of life. However, a single TACE operation has limited therapeutic effect on liver cancer. Multiple embolizations can achieve the maximum tumor necrosis rate and prolong the patient's survival. The interval between TACE operations is determined according to the tumor's response and the patient's condition, usually 4-12 weeks.
