Liver resections are usually considered the treatment of choice for colorectal and neuroendocrine metastases. Recently, the morbidity and mortality rates for liver surgery have dramatically decreased. Therefore, hepatic resection has been applied in selected cases of non-colorectal, non-neuroendocrine hepatic metastases. We report our experience with three cases of liver metastases from lung carcinoma and review the literature, to evaluate the role of liver surgery for this indication.
