The common treatment methods for liver cancer can be divided into two types: surgical and non-surgical treatments. I. Surgical treatment includes liver transplantation and hepatectomy, which is the preferred treatment for liver cancer and can remove the tumor tissue completely and achieve the purpose of radical cure. At present, about 4,000 liver transplants are carried out in China every year, and the technology is very mature. Non-surgical treatment includes arterial chemoembolization, local ablation therapy (radiofrequency ablation, microwave ablation, alcohol injection, high-intensity focused ultrasound), radiotherapy and molecular targeted therapy, which are mainly used for patients who cannot receive surgical treatment due to various reasons, or adjuvant treatment before and after surgery. Among them, arterial chemoembolization, which is often referred to as interventional therapy, is the first choice of non-surgical treatment and is commonly used for patients with intermediate to advanced hepatocellular carcinoma that cannot be surgically resected to achieve the purpose of controlling the disease and prolonging survival. For early stage hepatocellular carcinoma patients with single tumor ≤125px in diameter or multiple nodules (within 3) with maximum diameter ≤75px, without vascular bile duct invasion and good liver function, radiofrequency or microwave ablation is the best alternative to surgery.
