Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in china. The insidious onset of liver cancer early symptoms or no obvious symptoms, rapid progression, it usually is in late stage, and the vast majority of China's liver cancer patients had a history of cirrhosis, liver function, and tumor location, the number of patients with systemic conditions and other factors, the resection rate of less than 20%, prognosis poor. For those who can not be resected, the need for the use of non surgical treatment, in order to reduce symptoms, improve quality of life and prolong the survival of the purpose. In the method of non operative treatment of liver cancer, ultrasound guided microwave ablation is a minimally invasive technique for the treatment of liver cancer.
A what is ultrasound guided microwave ablation for liver cancer?
Ultrasound guided percutaneous microwave ablation of liver cancer in ultrasound guided liver tumor surveillance, needle puncture site into the microwave antenna scheduled, according to tumor size power and time combination, time usually takes 3-10 minutes. In the tumor tissue of polar molecules in high speed under the action of microwave field, mutual friction, when the temperature reached 60 degrees, cancer cell protein coagulation, necrosis of tumor tissue were absorbed. At the same time, the necrotic tumor tissue can stimulate the body's immune system, improve the body's immune system.
B ultrasound ablation of liver cancer what are the advantages? Ultrasound ablation of liver cancer is mainly the following:
1, minimally invasive, patients with small damage, pain, fast recovery.
2, the operation time is short, generally not more than 10 minutes.
3, safe, no radiotherapy and chemotherapy side effects, does not damage the immune system, on the contrary can improve immunity.
4, the effect is exact, direct ablation of tumor cells damaged.
5, can be combined with chemotherapy, radiotherapy or surgery.
6, suitable for advanced surgery, tumor recurrence or metastasis after operation.
7, for less than 5 cm of liver cancer can be obtained with surgical resection similar to the long-term survival.
8, can be repeated treatment.
9, the cost of a single treatment is lower than surgery.
C ultrasound ablation of liver cancer is safe?
Ultrasound ablation is a minimally invasive treatment for liver cancer, high safety. The general complications in the short-term pain of hepatic region, less than 3 weeks duration of fever was the most common, most without special treatment can be relieved, others include: nausea, skin burns, pleural effusion, dyspnea, subcapsular hematoma of the liver, bile duct stricture. Serious complications are rare.
D what kind of patients are suitable for ultrasound ablation therapy?
Ultrasound ablation of liver cancer is usually applied to single tumor, the maximum diameter is less than 5 cm, or the number of tumors is less than 3, and the maximum diameter of less than 3 cm. No vessel, bile duct and adjacent organ invasion and distant metastasis. The grade of liver function as Child-Pugh A or B, or by medical treatment to A or B. Sometimes, for unresectable larger than 5 cm in diameter of single tumor, or maximum diameter greater than 3 cm tumor, ultrasound ablation can also be regarded as a part of palliative treatment, the tumor load.
