大肠癌是常见的恶性肿瘤之一,发病率及死亡率亦逐年上升,严重威胁人们的生命。目前对大肠癌的治疗仍是以手术为主、辅以局部或全身放疗及化疗的综合治疗。早期大肠癌手术治疗效果明确,但有20～25%左右的患者在首诊时已有其它器官的转移给治疗带来了困难。而靶向治疗作为一种新的治疗手段,为晚期大肠癌的治疗开辟了新途径。 Colorectal cancer is one of the common malignant tumors. The morbidity and mortality also increase year by year, which seriously threatens people’s lives. Currently the treatment of colorectal cancer is still based surgery, supplemented by local or systemic radiotherapy and chemotherapy combined treatment. Early surgical treatment of colorectal cancer has a clear effect, but about 20 to 25% of patients in the first consultation has been the transfer of other organs to the treatment of the difficulties. Targeted therapy as a new treatment for the treatment of advanced colorectal cancer has opened up new ways.
