收集１９８４年１２月～１９９４年１１月间经手术和病理证实的结直肠癌肝转移病人３２例。分析其病史、术前检查结果和肝转移灶的特点，发现病史超过半年、癌肿绕肠管３／４周以上和／或ＣＥＡ异常增高者，肝转移的可能性很大。Ｂ超和ＣＴ是定位诊断的主要方法，但只能发现较大的转移灶，它们在本组的阳性率分别只有３１％和４６．２％。对于高度怀疑肝转移而术中仔细探查仍未发现转移灶者，术后密切随访有助于转移性肝癌的早期诊断。
Thirty-two patients with colorectal liver metastases confirmed by surgery and pathology between December 1984 and November 1994 were collected. Analysis of the medical history, preoperative examination results, and features of liver metastases revealed that patients with a history of more than six months, 3/4 weeks or more of cancer bypass, and/or abnormally high CEA were more likely to have liver metastases. B-ultrasonography and CT are the main methods for localization diagnosis, but only large metastases can be found. Their positive rates in this group were only 31% and 46.2%, respectively. For those who are highly suspicious of liver metastases and have not been found to have metastases after careful exploration during the operation, close follow-up after surgery can help early diagnosis of metastatic liver cancer.
