Which treatment method is best for middle and late stage liver cancer? The most suitable treatment method for middle and late stage liver cancer

Interventional treatment of liver cancer is to introduce special puncture needles, catheters, guide wires, balloons, stents, drainage tubes and other precision instruments into the human body under the guidance of medical imaging equipment to diagnose and locally treat some liver diseases, including primary liver cancer, metastatic liver cancer, hepatic hemangioma, liver cyst, cirrhosis, portal hypertension, intractable ascites and gastrointestinal bleeding, hepatic vein occlusion (Budd-Chiari syndrome), benign and malignant obstruction of the bile duct, liver bleeding, etc., as well as liver puncture biopsy.

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 advanced liver cancer with large or numerous tumors, transcatheter arterial chemoembolization 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 transcatheter arterial chemoembolization 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 transcatheter arterial chemoembolizations is determined according to the tumor's response and the patient's condition, usually 4-12 weeks.
