Result of liver resection as treatment for metastases from noncolorectal cancer

Abstract

Background and objectives: While liver resection for metastatic disease from colorectal cancer extends survival in selected patients, the efficacy of hepatectomy for metastases from other malignancies has not been defined.

Methods: Between 1988 and 1998, 20 hepatic resections were performed in 18 patients (2 underwent a double resection due to recurrence) as treatment of noncolorectal metastases. One-, 2-, and 5-year overall and disease-related actuarial survival rates were calculated.

Results: No intraoperative or early postoperative deaths were reported. Seven minor (30%) and 1 major (5%) postoperative complications occurred; mean blood loss was 401 +/- 324 ml. In 25% of patients, intra- or postoperative blood transfusion was needed. The mean postoperative hospital stay was 13. 2 days (range 9-23). The overall actuarial survival rate was 54% at 1 year, 42% at 2 years, and 21% at 5 years (mean 38 +/- 11 months). Survival is related to the primary tumor nature.

Conclusions: Hepatic resection for metastases from noncolorectal carcinoma is safe and feasible, with a relatively low incidence of intra- or postoperative complications and a short hospital stay. Although it achieves good results in terms of survival in patients suffering from neuroendocrine metastases, it could also have a cytoreductive effect for other tumors.
