    Abstract:
    BACKGROUND: A significant number of patients with colorectal metastatic disease confined to the liver are inoperable at assessment. For these patients, the outlook is poor. Chemotherapy can 'down-stage' some tumours and render them operable. The authors present a series of patients with inoperable disease despite down-staging with chemotherapy, who underwent a two-stage resection to clear their metastatic disease. METHODS: The case-notes of 11 patients who were found to have inoperable hepatic metastatic disease were identified using computerised medical records and mean hospital stay, survival and long-term follow-up data was noted. RESULTS: The mean follow-up from initial resection was 13.5 months (range of 5-20 months). Three deaths were recorded in the follow-up interval. Causes of death included recurrence of hepatic disease following completion of two-stage resection, progression of original hepatic disease leading to inoperability at second stage operation and recurrence of original primary colorectal tumour. The mean survival in the patients who died was 17 months (range of 15-19 months). The remaining patients are alive to date with six patients showing no evidence of hepatic recurrence, follow-up period of 13 months (range of 8-20 months). One patient developed de novo prostate cancer and is awaiting his second liver resection, and one patient has stable hepatic disease with no evidence of progression. CONCLUSION: Two-stage liver resection can prolong survival when compared to chemotherapy alone, with a recurrence rate equivalent to ablation techniques. Longer-term studies are needed for further evaluation.
