Background: The role of liver resection for non-colorectal, non-neuroendocrine, non-sarcoma (NCNNNS) metastases is ill-defined. This study aimed to examine the oncologic outcomes of liver resection in such patients. Methods: A retrospective analysis of liver resection for NCNNNS metastases was performed at two large centers. Liver resection was offered selectively in patients with stable disease. Oncologic outcomes were examined using the Kaplan-Meier method. Results: Fifty-two patients underwent liver resection for NCNNNS metastases. Overall 5-year survival was 58%. Five-year survival was 85% for breast metastases, 66% for ocular melanoma, 83% for other melanomas, 50% for gastro-esophageal metastases, and 0% for renal cell carcinoma metastases. A contemporary colorectal liver metastasis cohort had a survival of 63% (p=0.89). Conclusions: Liver resection is an effective option in the management of selected patients with NCNNNS metastases which have been deemed stable. Five-year survival rates were comparable to that of a contemporary cohort of patients with colorectal liver metastases in carefully selected patients. Further, larger studies are required to help identify potential prognostic variables and aid in decision-making in this heterogeneous population.
