title: Liver resection for noncolorectal, nonneuroendocrine metastases.
abstract: In noncolorectal, nonendocrine liver metastases, the role of surgery is less define than in colorectal or neuroendocrine cancer. This role is marginal as liver is not the primary site of metastases of these cancers. Less than 2 to 5% of the patients with these malignancies might be one day considered as potential candidates for liver resection, as most patients suffer from extra hepatic tumour spread at the time they develop liver involvement. However, in these few cases with liver metastases only, as no other therapeutic option may provide mid- or long-term tumour-free survival, liver resection is indicated in resectable liver metastases. Some prognostic factors have been established in the literature from the few published series: unique versus multiple hepatic metastases, unilobar vs bilobar, metachronous vs synchronous, R0 vs R1 or R2 liver resections. The type of primary tumour is also of great importance, as cutaneous melanoma, pancreatic and gastric adenocarcinoma have a very bad prognosis for liver resection of metastases, even after R0 resection. In these cases, percutaneous or laparoscopic radiofrequency ablation may find its place. In sarcoma, breast carcinoma, uveal melanoma, and genitourinary cancers, liver resection may provide satisfactory long-term results in selected cases, and is the standard of care for isolated, resectable metastasis. However, due to the scarcity of indication of liver resection for noncolorectal, nonneuroendocrine metastases, the decision should be multidisciplinary, and the patients should be informed of the advantages and pitfalls of the surgical procedure.
