SURGICAL TREATMENT OF LIVER METASTASES FROM COLORECTAL CANCER PATIENT SELECTION AND ONCOLOGICAL OUTCOME

The indications for surgical resection of liver metastases from colorectal cancer remain controversial. Clinical, pathological, and outcome data for 418 consecutive patients undergoing hepatectomy between 1984 and 1998 were examined. The over-all 5-year survival rate was 42%, and the 10-year survival rate was 31%. The 5-year survival rate of patients with four or more nodules was 24%, with 20 patients surviving for more than 5 years. Five factors were found to be significant and independent predictors of poor long-term outcome by multivariate analysis. The preoperative scoring system reported by Fong et al was double-checked in our 418 patients and was found to be useful to predict long-term outcome after hepatectomy. It is clear that liver resection alone has limitations. Therefore clinical risk scoring (CRS) and effective intravenous systemic chemotherapy to prevent recurrence both in the remaining liver and lung should be established to improve survival outcome in patients with poor prognostic factors after liver resection.
