原发性肝癌切除术后肝外转移灶的观察

探讨原发性肝癌肝外转移的某些特性。方法：收集１１年内在我院施行了根治性肝切除术,后出现肝外转移而肝内无复发的３５例肝癌患者的临床资料,进行分析。结果：３５例肝癌根治性切除术后,分别于术后１个月到８年出现临床可以查知的转移灶而无直内复发,其中８例,患者于术后３－８年才发现肝外转移灶。

The observation of distant metastasis of primary liver cancer after hepatectomy

Objective: To investigate some properties of metastasis of primary liver cancer(PLC). Methods: We collected 35 cases of PLC who received radical PLC resection in recent 11 years in our hospital. Distant metastases had been found after operation, but no evidence of intrahepatic recurrence. Result: Distant metastases of these cases were not found in 22. 9% (8/35) patients until three years after operation. Conclusions: Metastases of PLC can persist for up to 7 years in a state of "tumor dormancy". It is an important reason for long term recurrence. Therapeutic programs for patients who may exist metastases after operation, would have important significance.
