Abstract
Background: The aim of our study was to analyze the survival of patients who were operated from liver metastases. This paper is a retrospective study of the case reports from the Clinic for Operative Oncology - Oncology Institute of Vojvodina. The study included all the patients treated operatively for secondary malignant liver tumors in the period from May 2003 to May 2007. Methods: The study included 33 patients (17 men and 16 women). The mean age of patients was 57.8 years (range, 27-75 years). In 23 patients, (69.7%) metastases were of colorectal origin, while in 10 patients (30.3%) metastases originated from some other organs. Results: Hepatectomies were performed in 54.54% and metastasectomies in 45.45% of patients. More severe postoperative complications (which required repeated surgery) were registered in 3.03% of patients. Intraoperative mortality was 3.03% and postoperative mortality was 12.12%. Liver re-resection was performed in 21.21% of patients. An overall one-year survival was 75.76%, and a tree-year survival was 43.75%. One-year survival in patients with colorectal metastases was 86.96% and three-year survival was 50%, while in patients with metastases originating from some other organs, one-year survival was 70% and three-year survival was only 25%. Intrahospital mortality in patients with colorectal metastases was 8.7% while in patients with non-colorectal metastases it was 30%. Conclusion: The aim of this paper was to show that only surgical removal of metastases can lead to life quality improvement and to prolongation of the overall survival and that modern neoadjuvant and biological therapies may increase resectability of the inoperable changes.

Summary
Liver is an organ, which, most often, metastasizes from the colorectal carcinoma, breast carcinoma, malignant lung tumor, and malignant genitourinary tract tumor. The number of patients, operated on due to liver metastases of the colorectal carcinoma is very small in comparison to frequency of the primary carcinoma and its tendency to metastasize [4,5]. Excision of one or more metastases from liver can be performed only if all the observed metastatic changes can be removed and if there is no such metastatic change left, which is not visible during the operation, but which is confirmed by visual techniques. This means that those metastases, visible should be removed
