结直肠癌肝转移(colorectal liver metastases,CRLM)是造成结直肠癌(colorectal cancer,CRC)患者死亡的最主要原因之一,手术切除是CRLM患者可能获得长期生存的关键,但CRC患者在发现肝转移病灶时,仅大约20%的患者肝转移灶可以手术切除,而其他的患者往往由于没有可能进行根治性切除或手术切除后残存的肝脏体积<30%,而失去了切除肝转移灶的机会[1]。 Colorectal liver metastases (CRLM) is one of the most important causes of death in patients with colorectal cancer (CRC). Surgical resection is the key to long-term survival in patients with CRLM, but liver cancer is found in patients with CRC. At metastatic sites, only about 20% of patients have liver metastases that can be surgically removed, while other patients often lose the opportunity to remove liver metastases because they do not have the possibility of undergoing radical resection or surgical resection of less than 30% of the remaining liver volume.
