Hepatocellular carcinoma interventional therapy, known as hepatocellular carcinoma interventional therapy, is the least invasive treatment method that involves making tiny channels of several millimeters in diameter in blood vessels or skin, or treating the lesion locally under the guidance of imaging equipment (angiography, fluoroscopy, CT, MR, B-ultrasound) without opening an incision to expose the lesion. Hepatocellular carcinoma interventional therapy is a kind of regional local chemotherapy by injecting anti-cancer drugs or embolic agents into the hepatic artery through the femoral artery cannula. It is the first choice of non-open surgery for hepatocellular carcinoma and its efficacy has been confirmed. Comprehensive tumor staging treatment is to apply the available treatments in a planned and rational manner according to the patient’s body condition, pathological type, invasion scope and development trend of the tumor, so as to maximize the cure rate and improve the survival quality. It is a new type of treatment program for tumors at the present stage and is the basic principle of most tumor treatments. Advantages of hepatocellular carcinoma interventional therapy 1. Precise efficacy. Successful treatment can see rapid decrease of AFP, shrinkage of tumor and pain relief. 2.Mechanical science: the local drug concentration of interventional therapy is tens of times higher than that of systemic chemotherapy, and the blood supply of tumor is blocked, so the two-pronged treatment is effective and less toxic than systemic chemotherapy. 3. Interventional treatment for liver cancer is simple and easy to operate, safe and reliable. 4.It can be performed even for old and weak people and people with certain diseases, without general anesthesia and keeping awake. 5.Diagnostic imaging is clear and can be repeated for multiple comparisons. 6.For some hepatocellular carcinoma, it can be reduced in size and then resected in two steps. 7.It can be used as one of the important means of comprehensive treatment for advanced tumors. 8.The cost of hepatocellular carcinoma intervention is relatively low. Disadvantages of liver cancer interventional therapy 1.Despite super-selective entry, there are still obvious side effects, with the most reactions in digestive tract, which bring discomfort to human body. 2.The main blood supply of liver cancer depends on hepatic artery, but there is portal vein blood supply around the cancer mass, so that the cancer cells can survive secretly. The catheter should be super-selected to enter the blood supply artery for better efficacy, but sometimes it is difficult to enter the hepatic artery. However, sometimes it is difficult to enter the hepatic artery, while some hepatocellular carcinoma can have multi-vessel blood supply. Pay attention to diet First of all, it is important to emphasize that the diet structure should be reasonable. In principle, the diet of liver cancer requires diversified recipes: color, flavor, softness and digestibility. As the digestive function of liver cancer patients has decreased and their appetite is not good, so pay attention to the changes of recipes and choose some foods that patients like to eat; and advocate the combination of meat and vegetarian foods to complement each other: the nutritional value of meat and vegetarian foods have their respective strengths, and the most important feature of meat food is that it contains essential amino acids and high quality proteins for human body; while vegetable proteins in vegetarian foods, except soybeans and soybean products, contain incomplete essential amino acids and the quality of protein is easy to be poor. The quality of protein is easy to be poor, so it should be balanced in the diet of liver cancer. Secondly, there should be enough calories. Sufficient calories can reduce the consumption of protein, reduce the burden on the liver and facilitate the synthesis of tissue protein. The daily food calories for liver cancer patients are more appropriate according to the principle of 2500 – 2800 kcal. If weight-based, the daily calorie requirement for liver cancer diet should be about 35–40 kcal per kg of body weight. Finally, it is emphasized that patients with hepatocellular carcinoma should be provided with appropriate amount of liquid in the diet: supply sufficient liquid to dilute bile and promote the discharge of metabolites from the body, especially for patients with jaundice but without ascites, they can drink a lot of water. Drink more juice, rice soup, honey water, watermelon juice, etc. However, when liver cancer ascites patients with obvious hyponatremia, water intake should be restricted in the diet.
