Liver cancer is a common clinical malignant tumor, which is extremely harmful. Liver cancer is divided into primary liver cancer and secondary liver cancer. Primary liver cancer is divided into hepatocellular carcinoma and intrahepatic bile duct cancer, while secondary liver cancer mainly refers to metastatic cancer of lung cancer, thyroid cancer, bone cancer, stomach cancer, intestinal cancer, uterine cancer, etc. Typical symptoms of hepatocellular carcinoma include painless lumps in liver, jaundice, poor circulation, some patients even do not have any symptoms, and some only have fever symptoms. Others, such as abdominal pain, ascites, bloating, and symptoms of primary cancer. Diagnosis of liver cancer mainly relies on liver ultrasound, liver CT and enhanced CT scan, liver aspiration cytology examination to make clear diagnosis, and other biochemical full items, tumor markers, BNP, blood routine, etc. to assess the whole physical condition of patients and formulate individualized treatment plan. The main treatment options for liver cancer are as follows: 1. surgery, 2. hepatic artery embolization chemotherapy, 3. chemotherapy, 4. radiotherapy, 5. radiofrequency ablation, 6. conservative treatment. 1.Surgical treatment. There are focal resection and liver transplantation. There are obvious indications for focal resection surgery: no ascites and distant metastasis, prolonged prothrombin time of coagulation function not more than 50%, heart, liver and kidney function tolerance, liver resection not more than 70% in normal liver function; moderate cirrhosis not more than 50% or only the left half of the liver can be resected; severe cirrhosis cannot be lobectomized and pathology confirmed that more than 80% of liver cancer combined with cirrhosis is recognized to local resection instead of regular lobectomy. Although liver transplantation is a method for treating liver cancer and has been widely reported abroad, its status in the treatment of liver cancer has not been confirmed for a long time, and patients often die of recurrence due to the application of long-term immunosuppressive drugs after surgery, and it is still difficult to be promoted in developing countries in recent years due to the source of donors and huge costs. 2.Hepatic artery embolization chemotherapy. This is the first choice for patients with inoperable hepatocellular carcinoma. Through femoral artery puncture, a catheter is inserted into the hepatic artery supplying the growth of hepatocellular carcinoma, and chemotherapeutic drugs are injected, and the corresponding hepatic artery is blocked with embolization agent. 3. Chemotherapy. It can be applied alone or in combination after surgery. The main combination chemotherapy regimens for hepatocellular carcinoma are: oxaliplatin plus calcium folinate plus fluorouracil regimen; capecitabine plus oxaliplatin regimen; capecitabine plus cisplatin regimen; adriamycin plus oxaliplatin regimen, etc. The side effects are relatively large and the efficacy is not certain. 4.Radiotherapy. Primary liver cancer is not sensitive to radiotherapy. Radiotherapy can be applied alone or as postoperative or post-chemotherapy adjuvant treatment. 5.Radiofrequency ablation. Radiofrequency ablation of hepatocellular carcinoma is a clinical treatment method that uses electrode needles to puncture into the tumor through the skin and liver to completely destroy the tumor through the principle of heat production. Radiofrequency ablation for liver cancer is applicable to early stage liver cancer, i.e. grade A liver cancer. Radiofrequency ablation for hepatocellular carcinoma has the characteristics of small invasion, good patient tolerance, short hospitalization time and complications. After surgery, fever occurs due to tumor necrosis, and body temperature is normal after absorption of necrotic tumor tissue. 6.Conservative treatment. It is the choice of patients with advanced liver cancer, mainly to reduce symptoms, symptomatic treatment, hepatoprotective treatment, strengthen nutritional support treatment, apply fatty milk human albumin amino acid, oxygen absorption, release ascites to reduce abdominal pressure and so on. Eat a light diet, you can moderate the amount of fish and other high-quality protein. The enlarged liver is very fragile, avoid bumping and belt tying too tightly to avoid liver rupture.
