BACKGROUND: Extrahepatic malignant disease has always been considered an absolute contraindication to hepatectomy for colorectal liver metastases. This study reports the long-term outcome and prognostic factors of patients undergoing extrahepatic disease resection simultaneously with hepatectomy for liver metastases. METHODS: From January 1987 to January 2001, 75 patients underwent a complete R0 resection of extrahepatic disease simultaneously with hepatectomy for colorectal liver metastases. They were inscribed in a registry and then prospectively followed up. They represented 25% of the 294 patients who underwent an R0 hepatectomy for colorectal liver metastases during the same period. RESULTS: The mortality rate was 2.7%, and morbidity was 25%. After a median follow-up of 4.9 years (range, 1.7-13.4 years), the overall 3- and 5-year survival rates were 45% and 28%, respectively. By using a Cox model, there was a significant difference in survival between patients with single versus multiple sites of extrahepatic disease. Also, the presence of more than five liver metastases was a significant parameter. CONCLUSIONS: Extrahepatic disease in colorectal cancer patients with liver metastases should no longer be considered as a contraindication to hepatectomy. However, this intended R0 resection cannot be performed in 50% of laparotomized patients, and negative prognostic factors for surgery include the presence of multiple extrahepatic disease sites or more than five liver metastases.
