抄録

The recurrence was observed after curative resection of liver metastasis of colorectal carcinoma in twenty-four of 33 cases, intrahepatic recurrence only was in 7. extrahepatic recurrence only in 6 and both intra and extrahepatic recurrence in 11. All intrahepatic recurrence was occurred within 2 years after surgery. Intrahepatic recurrence was related with vascular invasion of colorectal carcinoma, timing and number of liver metastasis and surgical procedure. Extrahepatic recurrence was related with lymph node metastasis of colorectal carcinoma and distribution of liver metastasis. Survival was related with lymph node metastasis and vascular invasion of colorectal carcinom, size of liver metastasis, but was not related with surgical procedure. The systematic resection of liver metastasis is important to reduce intrahepatic recurrence, but systematic hepatectomy couldn't improve the survival. Therefore, prohibition and early detection and treatment of extrahepatic recurrence is also important.
