BACKGROUND: Liver resection is currently accepted as the only potential cure for patients with metastases of colorectal tumors in the liver. However, cancer will recur in more than 70% of patients. METHODS: In the 7 years to December 1997, 60 patients underwent liver resections for colorectal metastases at our institute. Of these, 20 patients had repeated surgical resections for recurrent disease of the liver and other organs. Another 2 patients had undergone previous hepatectomy elsewhere. The clinical data for these patients were reviewed. RESULTS: The median interval between the 2 resections was 16 months. Eighteen hepatectomies, 6 lung resections, and 1 pancreatoduodenectomy were performed in 22 patients. Operative mortality and complication rates were 0% and 18%, respectively. At a median follow-up of 25 months after repeated resection, the survival rate in these patients was 73% at 2 years (12 of 16 evaluable patients are surviving) and 22% at 5 years (2 of 10 evaluable patients are surviving); the median survival time was 44 months. CONCLUSIONS: Repeated resections for recurrent colorectal metastases yield comparable results to first liver resections in operative mortality and morbidity rates, survival time, and pattern of recurrence. Although the number of patients surviving more than 5 years is still limited, the absence of other proven treatments supports the concept of an aggressive resectional approach for these patients.
