肝癌是我国发病率较高的消化系统恶性肿瘤,手术治疗效果差,易复发,而且确诊时多为中晚期肝癌。此时肿瘤生长迅速,体积较大,或多伴有广泛转移,已错过手术切除的最佳治疗时机。而选择药物化学治疗或介入治疗,不仅不良反应大,而且效果治疗也不甚理想。伽马刀经过CT和磁共振等现代影像技术精确地定于某一部位。它的定位极准确,误差常<0.5 mm。伽马刀与普通放射治疗相比具有显著优势,放射治疗的准确度高,可使肿瘤区域得到高剂量的聚焦射线,而对
Liver cancer is a high incidence of digestive system malignancies in our country, poor surgical treatment, easy to relapse, and when diagnosed mostly in advanced liver cancer. At this time rapid tumor growth, larger, or more with extensive metastases, surgery has missed the best timing of treatment. The choice of chemical chemotherapy or interventional therapy, not only adverse reactions, and the effect of treatment is not ideal. Gamma Knife through CT and MRI and other modern imaging technology precisely at a certain location. Its positioning is very accurate, the error often <0.5 mm. Gamma Knife compared with ordinary radiotherapy has a significant advantage, the high accuracy of radiation therapy, the tumor area can be high-dose focused rays, and
