title: [Indications and operative procedures for neuroendocrine liver metastases].
abstract: Neuroendocrine malignancies encompass a variety of tumors that differ considerably in origin, hormonal activity, and biological behavior. Because of their rarity most therapeutic recommendations have been based on limited evidence from small retrospective series observing miscellaneous patient cohorts. Only in recent years proposals for TNM and histological grading systems have been elaborated that allow further stratification of patients suffering from these tumors. Especially patients with well and moderately differentiated neuroendocrine malignancies benefit from resection of liver metastases, improving the 5-year survival rate from <50% to 80%. Orthotopic liver transplantation can likewise improve survival in carefully selected patients. New developments in imaging modalities, intensive care treatment, and in liver surgery itself have broadened the selection of potentially resectable tumors.
