当前肝癌的五年总生存率居我国十七种常见恶性肿瘤的倒数第二.肝癌的发生和发展是一个进行性加重的过程.目前的临床研究主要是针对中间阶段,即医院内阶段的诊疗原理及方法的探索.尤其是针对肝癌发生的癌前阶段和治疗后的康复阶段的研究现在还严重不足.提出阶梯式防治的策略旨在强调只有对肝癌患者进行全病程的防治研究,才有可能显著改善我国肝癌的总体疗效.“,”The five-year overall survival rate with liver cancer currently ranks the second lowest among seventeen common malignant tumors in China.The occurrence and development of liver cancer is a process of progressive exacerbation.Nowadays,the clinical research is mainly aimed at the intermediate stage,that is,the exploration of the principle and method of diagnosis and treatment in the hospital.Notably,the research on the precancerous stage and the recovery stage after treatment of liver cancer are still seriously inadequate.We put forward a stepwise strategy to emphasize that only the full course of prevention and treatment study on liver cancer patients can significantly improve the overall efficacy of liver cancer in China.
