作者总结1987～1993年期间收治的533例原发性肺癌,其中生前临床确诊有肝转移者63例(占11.8％）,肺癌诊断同时已有肝转移者40例（63.5％）,其后治疗过程中出现肝转移者23例（36.5％）。肝脏是原发性肺癌转移的好发部位之一。文献报告肺癌肝转移发生率为38％～44％,而本组临床诊断率较低,此虽与腹部超声、CT等检查方法的诊断率有关,但一般认为多数情况下,是由于肝转移早期缺少症状,且只是在确诊肺癌时重视肝转移的筛查,而其后即使出现新的转移,也未能进行充分的检查所致。
The authors summarized 533 cases of primary lung cancer treated during the period from 1987 to 1993. Among them, 63 cases (11.8%) were diagnosed with liver metastases before their lifetime diagnosis, while 40 cases (63.5%) of liver metastases were diagnosed with lung cancer. During the process, there were 23 cases (36.5%) of liver metastases. The liver is one of the major sites of metastasis of primary lung cancer. The literature reports that the incidence of liver metastases from lung cancer is 38% to 44%, but the clinical diagnosis rate in this group is relatively low. Although this is related to the diagnostic rate of abdominal ultrasound, CT, etc., it is generally considered that in most cases, it is due to early liver metastasis. The lack of symptoms, and the importance of screening for hepatic metastases only when lung cancer is diagnosed, and subsequent new metastases, have not been adequately examined.
