Background:
Indications for resection of liver metastases from colorectal cancer and surgical strategies are still under debate.
Methods:
We have retrospectively reviewed the outcome of 660 patients after 685 liver resections for metastases of colorectal cancer in our institution from 1988 to 2004. All surviving patients have a minimum follow-up period of 1 year. The longest follow-up in these patients is 16 years. Three different time periods of 5 to 6 years each were analyzed.
Results:
The 30- and 60-day mortality rates were 1.5% (n = 10) and 2.2 % (n = 15), respectively. The rate of formally curative (R0) resections was 84%. Five-year survival rates in all patients and in patients after R0 resection were 37% and 42%, respectively. If only resections from 1999 to 2004 were considered, 5-year survival in patients after R0 resection was 50%. In a multivariate analysis, surgical radicality, ligamental lymph node involvement, number of liver metastases, and time period, in which the liver resection had been performed, were independent prognostic parameters.
Conclusions:
Outcome after liver resection for metastases from colorectal cancer has constantly improved. A formally curative resection is the most relevant prognostic parameter. Number of liver metastases and, in the few patients concerned, lymph node infiltration of the hepatoduodenal ligament, were further prognostic parameters.
