大肠癌为全球发病率第三位的肿瘤,也是我国最常见的恶性肿瘤之一。文献报道,约40%的大肠癌患者死于肝转移,15%～25%的大肠癌患者在原发肿瘤诊断时即有肝转移,20%左右的患者原发肿瘤治疗后出现肝转移[1,2]。因此,大肠癌肝转移的诊断与治疗仍是医学研究的难点。本文针对大肠癌肝转移的诊断与治疗作一综述。 Colorectal cancer is the third most common cancer in the world and one of the most common malignant tumors in our country. It has been reported in the literature that about 40% of patients with colorectal cancer die of liver metastases and 15-25% of patients with colorectal cancer have liver metastases at the time of primary tumor diagnosis, and about 20% of patients have liver metastases after primary tumor treatment [1 ,2]. Therefore, the diagnosis and treatment of liver metastasis of colorectal cancer is still the difficulty of medical research. This article reviews the diagnosis and treatment of liver metastasis of colorectal cancer.
