Primary liver cancer is one of the common malignant tumors in my country. The mortality rate ranks third among digestive system malignant tumors. About 110,000 people die of liver cancer in my country each year, accounting for 45% of the deaths from liver cancer in the world. Due to the monitoring of high-risk groups by serum alpha-fetoprotein (AFP) detection combined with ultrasound imaging, liver cancer can be diagnosed in the subclinical stage, and the long-term effect of early resection is particularly significant. In addition, active comprehensive treatment has significantly improved the five-year survival rate of liver cancer. This disease can occur at any age, with the highest incidence at 40 to 49 years old, and the ratio of men to women is 2 to 5:1.
