Liver cancer is one of the common malignant tumors in China, and its incidence rate has increased significantly in recent years. Due to the insidious onset of liver cancer, no or no obvious symptoms in the early stage, and rapid progress, most of them are already in the middle and late stage when found, and most of the liver cancer patients in China have a history of cirrhosis and poor liver function. For those patients who cannot be surgically resected, they need to actively adopt non-surgical treatment methods to reduce symptoms, improve life quality and prolong survival. Among the many non-surgical treatment methods for liver cancer, ultrasound-guided microwave ablation is one of the fast-developing minimally invasive thermal ablation techniques for liver cancer treatment in recent years. What is ultrasound-guided microwave ablation for liver cancer treatment? Ultrasound-guided microwave ablation for liver cancer treatment is to deliver a microwave antenna needle into the predetermined liver tumor site under the surveillance guidance of ultrasound, and the combination of power and time is set according to the size of the tumor, and the action time usually takes 3-10 minutes. The polar molecules in the tumor tissue move at high speed under the action of microwave field and generate heat by friction with each other. When the temperature reaches about 60 degrees, the cancer cell protein denatures and coagulates, and the necrotic tumor tissue is absorbed by the patient’s body. At the same time, the necrotic tumor tissue can stimulate the immune system of the body and improve the immunity of the body. What are the advantages of ultrasound ablation for liver cancer treatment? The main advantages of ultrasonic ablation for liver cancer treatment are as follows: 1. Minimally invasive, less patient damage, less pain and faster recovery. 2. 2. Short treatment operation time, generally less than 10 minutes. 3. Safe, no toxic side effects of radiotherapy, no damage to the immune system, on the contrary, it can improve the immunity of the body. 4.The effect is exact, and the tumor cells are directly ablated and destroyed. 5.It can be combined with chemotherapy, radiotherapy or surgical treatment. 6.It is suitable for middle and late stage tumors that cannot be operated, recurrence or metastasis after surgery. 7.For hepatocellular carcinoma less than 5 cm, it can obtain long-term survival efficacy similar to that of surgical resection. 8.It can be repeatedly treated for many times. 9.The cost of single treatment is lower than surgery. Is ultrasound ablation safe for liver cancer treatment? Ultrasound ablation is a minimally invasive treatment for liver cancer, which is safe. The most common complications include pain in the liver area within a short period of time, hypothermia lasting less than 3 weeks, which can be relieved by itself without special treatment in most cases. Serious complications are less common. 4.What kind of patients are suitable for ultrasonic ablation treatment? Ultrasound ablation treatment for liver cancer is usually suitable for single tumor with maximum diameter less than 5 cm; or the number of tumors is less than 3 and the maximum diameter is less than 3 cm. There is no invasion of blood vessels, bile ducts and adjacent organs as well as distant metastasis.
