What is small liver cancer? Generally, the diameter is less than 3 cm in the early stage

Small liver cancer is also called subclinical liver cancer or early liver cancer. There are no obvious clinical symptoms and signs of liver cancer. Small liver cancer generally refers to liver cancer in which the maximum diameter of a single cancer nodule in hepatocellular carcinoma does not exceed 3 cm or the sum of the diameters of two cancer nodules does not exceed 3 cm. Patients often have no clinical symptoms. Tumor nodules are mostly spherical, with clear boundaries, uniform cross-sections, and no bleeding or necrosis. The standard for small liver cancer in my country is: the maximum diameter of a single cancer nodule does not exceed 3 cm; the number of multiple cancer nodules does not exceed two, and the sum of their maximum diameters should be less than 3 cm.

Hepatobiliary Surgery Chronic hepatitis history is a high-risk group for liver cancer in my country Liver cancer is a common malignant tumor in my country. The tumor is relatively hidden, and the liver has a strong compensatory ability, so early liver cancer is not easy to detect. In the subclinical stage of small liver cancer, the patient is asymptomatic, so it needs to be discovered in the high-risk population survey and physical examination of the middle-aged and elderly. Those who are over 40 years old and have a positive hepatitis B surface antigen and a history of chronic hepatitis are high-risk groups for liver cancer in my country. The detection rate of liver cancer screening in high-risk groups is 501/100,000, which is 34.5 times that of the census in the natural population. At present, most people advocate the use of the simple and sensitive AFP reverse hemagglutination method as a preliminary screening test, and the positive ones are then re-examined by radioimmunoassay. At the same time, ultrasound imaging is a simple and reliable imaging diagnosis method for liver cancer. It can detect cases with negative AFP or low AFP concentrations. Ultrasound diagnosis and AFP combined diagnosis are ideal screening methods for small liver cancer.

Small hepatocellular carcinoma after radical surgical resection of liver cancer The recurrence rate after surgical resection of liver cancer is very high, and most of them recur in the liver. After surgery, AFP decreases for a time, and then gradually increases with recurrence, or ultrasound or CT is checked after surgery. When it is discovered, its characteristic is that the tumor recurrence is mostly in the residual liver near the original resected liver. Small hepatocellular carcinoma obtained after comprehensive treatment of large liver cancer Comprehensive treatment of liver cancer includes transcatheter arterial embolization chemotherapy, guided chemotherapy, radiotherapy and intratumoral alcohol injection. Among them, if the tumor is an expansive type with a complete fibrous capsule, arterial embolization is the most effective. Recently, anhydrous alcohol is injected into the tumor through a Chiba needle under ultrasound guidance. After repeated injections, the tumor tissue coagulates and necrotizes, and the tumor volume is reduced by non-surgical methods, providing an opportunity for surgery.
