原发性肝癌是我国常见的恶性肿瘤,早期症状不明显,一旦出现症状,病情发展比较快,治疗后的一年生存率较低。近年由于应用甲胎蛋白检测方法开展肝癌普查以来,可以较早期地发现肝癌病人,甚至癌瘤直径只有1厘米的早期小肝癌也可以诊断出来,使肝癌的疗效有了明显提高。 Primary liver cancer is a common malignancy in China. The early symptoms are not obvious. Once symptoms occur, the condition develops rapidly, and the one-year survival rate after treatment is low. In recent years, due to the use of alpha-fetoprotein detection methods for liver cancer screening, liver cancer patients can be discovered earlier. Even early-stage small hepatocellular carcinomas with a tumor diameter of only 1 cm can be diagnosed and the efficacy of liver cancer can be significantly improved.
