Background/Aims:
We retrospectively reviewed our results with curative hepatic resection of metastases from colorectal carcinoma, and analyzed several factors of the primary tumor and liver metastases.
Methodology:
From 1988 to 1995, 90 patients underwent curative resection of colorectal liver metastases. The total mortality rate was 1.1%. Overall 5-year survival rate after hepatectomy was 37.9%.
Results:
Mesenteric lymph node metastases from the primary tumor and the prehepatectomy serum carcinoembryonic antigen level were significant. In multivariate analysis, positive mesenteric lymph node was an independent prognostic factor. In the recurrent patterns, mesenteric lymph node metastases were associated with extrahepatic recurrence after hepatectomy.
Conclusions:
The prehepatectomy carcinoembryonic antigen level and mesenteric lymph node metastases of the primary tumor were the most important predictive factors for long survival after hepatectomy. Patients with these risk factors should be closely followed up with regard not only to the remnant liver but also extrahepatic organs.
