1. The definition of small hepatocellular carcinoma definition of small liver cancer at home and abroad is not the same, the domestic standard is 5 cm in diameter as small liver cancer liver cancer, and the foreign standard is 2 cm. Surgical treatment of small hepatocellular carcinoma is still the first choice, if the patient is poor liver function, surgery can not be the first choice within the tumor ethanol injection. Poor efficacy of hepatic artery thrombosis. In recent years, liver transplantation in the treatment of small hepatocellular carcinoma in the attention.
2. Small hepatocellular carcinoma surgery: resection of small hepatocellular carcinoma by local excision, local resection not only improve the resection rate, lower mortality, but also improve the survival rate. Hilar liver resection more difficult in recent years because of experience, resection rate was significantly improved, even if the tumor is close to the inferior vena cava, as long as adequate preparation and sufficient level of technology can also be removed.
3. Liver transplantation: treatment of small hepatocellular carcinoma in liver transplantation not only removed the status of liver cancer, and removed the basis of all liver cancer, liver cancer is the presence of liver sclerosis susceptibility factors removed. Comparison recognized in recent years concluded that, compared with resection, liver transplantation has better effect. The question now is liver problems and funding sources, a large area of promotion is still difficult to achieve.
4. Embolization: Although the treatment of liver cancer have a good effect, but its efficacy by the constraints of the tumor blood supply, and the surrounding liver tissue on the foci of the lesions had no obvious potential therapeutic effect, often not as hepatocellular carcinoma the only way of treatment, and, because of small hepatocellular carcinoma often not rich arterial blood supply, its value of small hepatocellular carcinoma larger than treating liver cancer.
5. Immunological treatment or medical treatment: often used as adjuvant treatment of surgery, limited efficacy alone.
6. Anhydrous ethanol injection: the first is the application of local treatment of liver cancer means of liver damage due to infiltration by the scope of the impact of alcohol, only for small hepatocellular carcinoma, and its treatment are not sure, have been effective Local treatment of a more determined way (such as radiofrequency ablation) are replaced.
7. Treatment of small hepatocellular carcinoma in recent years in other patients with good liver function, tumor resectability, surgical methods are preferred. Recently, using ultrasound-guided radiofrequency ablation therapy gradually increased.
