PURPOSE: To present our experience in the treatment of patients with liver metastases from colorectal cancer.
METHODS: The surgical and histopathological records of our department dating from 1st January 1997 to 31 December 2016 were examined, searching for patients who have undergone surgical treatment of colorectal liver metastasis.
RESULTS: A total of 90 patients with colorectal liver metastases were treated in the last 20 years in our department. Their mean age was 65.28 years and 54 (60%) were male. The primary tumor was in the colon in 71 patients (78.9%) and in 19 (21.1%) patients in the rectum. Thirty-six (40%) patients presented with synchronous metastatic liver disease, from which 27 were subjected to simultaneous resection, 2 underwent a liver-first approach and 7 were subjected to resection of primary tumor first. Regarding the number of metastases 67 (74.4%) patients had single metastasis, 12 (13.3%) had 2 lesions, 4 (4.4%) had 3 lesions and 7 (7.8%) had 4-8 lesions. In-hospital and 30-day mortality was 3.85%. Median survival was 41 months.
CONCLUSION: Surgical resection is the treatment of choice for the management of liver metastasis from colorectal cancer and can be safely performed. Follow up of patients with colorectal cancer is imperative as metachronous metastasis presents in a significant percentage of patients with negative locoregional lymph nodes of the primary tumor. The order of resection doesn't seem to alter outcome in synchronous metastasis. Recurrence is common and re-resection if feasible is the only chance of cure.
