转移性肝癌在国外相当多见,与原发性肝癌相比约13～65:1,国内发病率低,约为原发性肝癌的1.2倍。临床所见的消化系统癌的肝转移远较其他系统的癌为多,约35～50%。Nims报告尸检统计胃、结肠、直肠的癌肿发生肝转移分别为44.5%、65.3%和47%。结直肠癌在初次手术时就有11～25%发生肝转移,约30%病人于结直肠癌的治疗性切除术后2年内死亡,发现肝转移后平均生存期6～10个月。
Metastatic liver cancer is quite common in foreign countries, and it is about 13 to 65:1 compared with primary liver cancer. The incidence in China is low, about 1.2 times that of primary liver cancer. The liver metastases of digestive system cancer seen in clinic are far more than those in other systems, about 35 to 50%. Nims reported autopsy of 44.5%, 65.3%, and 47% of liver metastases in gastric, colon, and rectal cancers, respectively. Liver metastasis occurs in 11 to 25% of colorectal cancers during initial surgery, and approximately 30% of patients die within 2 years of therapeutic resection of colorectal cancer. The average survival time after liver metastasis is 6 to 10 months.
