Can Gamma Knife treat liver cancer? What are the effects and side effects of Gamma Knife in treating liver cancer?

There are about 1 million cases of liver cancer every year in the world, and the incidence of liver cancer in my country accounts for 55% of the new cases in the world each year. As a country with a high incidence of hepatitis B, liver cancer in my country mostly develops through the three steps of liver disease: hepatitis, cirrhosis, and liver cancer.

Liver cancer originates in the liver tissue and is prone to invade adjacent tissues and the portal vein, metastasizing into the liver or to distant sites through the intrahepatic blood vessels and lymphatic channels. This determines the complexity and difficulty of treatment.

Liver cancer often appears as a round or oval shape in imaging, which is more suitable for Gamma Knife treatment. Its significance lies in increasing the tumor dose to improve the local tumor control rate and tumor-free survival rate, thereby reducing the distant metastasis rate, reducing the radiation dose to normal tissues, and reducing the incidence of complications.

Gamma Knife radical treatment is feasible for patients with good general condition, good liver function reserve, no ascites or a small amount of ascites, no jaundice or jaundice caused by compression of the first liver portal, tumor diameter 5cm-8cm, no intrahepatic spread and liver portal lymph node metastasis. For patients with advanced disease, Gamma Knife treatment can shrink tumors, relieve pain, improve general condition and improve quality of life.

Adverse reactions that may occur during Gamma Knife treatment of liver cancer patients include nausea, vomiting, anorexia, fatigue and loss of appetite, but they are relatively mild and can be recovered quickly after symptomatic treatment. They will not affect the progress of Gamma Knife treatment of the body; symptoms can also be relieved after stopping Gamma Knife treatment of the body.
