肝癌是我国常见的高度恶性肿瘤,预后极差。中晚期肝癌、转移性肝癌往往失去手术机会,介入与化疗的疗效也很有限。肝癌是开展适形放射放疗的理想器官,这是因为肝癌常规放疗法疗效欠佳,还因为它是一个再生能力极强的大器官,小的局部高剂量聚焦照射能有效摧毁肝癌病灶,而肝功能不受明显影响。我们采用立体三维适形放射治疗肝癌,取得一定疗效如下。 Liver cancer is a common malignant tumor in China, with a very poor prognosis. In advanced liver cancer, metastatic liver cancer often lose the chance of surgery, interventional and chemotherapy is also very limited. Liver cancer is the ideal organ to carry out conformal radiotherapy. This is because the conventional radiotherapy for liver cancer is ineffective, and because it is a large organ with strong regenerative ability, small local high-dose focused irradiation can effectively destroy the liver cancer and the liver Function is not significantly affected. We use three-dimensional conformal radiotherapy of liver cancer, achieved a certain effect is as follows.
