Liver cancer – a major killer of human health – is located in the third place of malignant tumor incidence, and is further divided into two categories: primary and secondary. Primary refers to the growth of liver itself. Secondary refers to metastasis from other organs, and most liver cancers are primary. The pathogenesis of primary liver cancer is still not clear, but the following causes are basically recognized: viral hepatitis, cirrhosis, aflatoxin contamination and harmful chemical environmental pollution. Hepatitis and cirrhosis account for more than 90% of the occurrence of hepatocellular carcinoma. The damage of hepatitis and cirrhosis to the liver function of patients is great, and it is a very important and absolutely cautious issue to choose the method to treat liver cancer on the basis of their long-term testing and treatment, as improper choice will aggravate the damage of liver function or even the failure of liver function, which will make the treatment of liver cancer come to nothing. How to choose the treatment for hepatitis, cirrhosis and liver cancer? The current treatment methods for liver cancer are basically as follows: surgery, intervention, chemotherapy and radiotherapy, traditional Chinese medicine and biology. The latter four methods are not effective or have inaccurate efficacy, while the first two are the main methods. Medical concept: surgery is the first choice for tumor treatment, but with the development of imaging technology, interventional treatment for liver cancer has taken up half of the ground. Surgical treatment: Only 20-25% of liver cancer are suitable for surgery, and the vast majority of them are not suitable for surgical conditions. Moreover, because liver cancer is based on hepatitis and cirrhosis, surgical trauma has a greater impact on liver function, and recovery of liver function after tumor removal is really a matter of anxiety for doctors and patients, sometimes the tumor is removed, but liver function never returns to normal, or ascites and Sometimes the tumor is removed, but the liver function never returns to normal, or ascites and liver failure appear, making the surgery seem useless. It is ideal to choose a method that can treat the tumor and minimize the damage to liver function. Interventional treatment: Interventional treatment of liver cancer is a mature technology, which is divided into two types: catheter intervention (arterial embolization) and local ablation. Catheter intervention is to inject embolic blocking agent to block the blood flow to the tumor and let the tumor die of ischemia, and at the same time, some chemotherapeutic drugs can be injected to act directly on the tumor. Liver cancer depends on arterial blood for 75% of its blood supply, so the effect of blocking arterial blood is very effective, but the effect of one kind of arterial blood supply is not obvious (lack of blood supply for liver cancer). In addition, 25% of the blood supply of hepatocellular carcinoma comes from portal vein, which cannot be embolized by catheter intervention, therefore, some hepatocellular carcinomas can survive even after arterial embolization by portal vein blood supply alone. As we can see, the catheter interventional approach for liver cancer has minimal impact on liver function, but it also has shortcomings. Local ablation, which is another type of intervention. The principle is that under the guidance of imaging, a needle is pierced into the tumor and locally heated to a temperature above 80°C to kill the tumor, or let the temperature drop below -120°C to freeze the tumor to death, alternating between freezing and heat to damage the tumor more completely. The former is thermal therapy, such as micro-blog, radio frequency, laser, and the latter is argon helium knife. This method of treating liver cancer is less damaging to liver function, and it is also a method recognized at home and abroad with positive efficacy. If the above two methods are used in combination, most of liver cancers can be effectively treated and a wider range of liver cancer types can be treated. To summarize the advantages of interventional methods for hepatocellular carcinoma arising from hepatitis and cirrhosis: 1. 2. Suitable for many types of liver cancer. 3. Definite curative effect.
