Long-term outcome in patients with adrenal metastases following resection of colorectal liver metastases.
BACKGROUND
The prognostic significance of adrenal metastases (AMs) in patients with colorectal liver metastases (CLMs) remains unknown. The aim of this study was to determine the influence of AMs on long-term outcome and the role of adrenalectomy in patients with CLMs.


METHODS
All patients resected for CLMs who developed AMs at a single institution between 1992 and 2006 were included in the study. Their long-term outcome was compared with that of all other patients resected for CLMs but without AMs.


RESULTS
Hepatectomy was performed in 796 patients, of whom 14 (1.8 per cent) developed AMs, a median of 28 months after initial diagnosis of CLMs; the remaining 782 patients (98.2 per cent) had no AMs. All 14 patients had chemotherapy, and ten went on to adrenalectomy. Median survival after diagnosis of CLMs was 50 months in patients with AMs versus 68 months in those without (P = 0.020). After diagnosis of AMs, median survival was 23 months, whether or not adrenalectomy was performed.


CONCLUSIONS
The development of AMs after liver resection for colorectal cancer deposits carries a poor prognosis, and adrenalectomy is probably not warranted.
