[Surgical interventions in liver metastases].
Surgical treatment of hepatic metastases is predominantly aimed at "curative" resection. This can be achieved in about 20% of colorectal secondaries, and is associated with a 30-40% 5-year survival. One to three metastases in the absence of extrahepatic disease are regarded a clear indication to resection. Among patients with non-colorectal malignancies, occasional long term survival was reported in leiomyosarcoma, breast cancer, and renal cancer metastases, respectively. Endocrine tumors such as carcinoid, gastrinoma, or pheochromocytoma, are different because of their remarkable symptoms along with a protracted natural history. Quality of life may be considerably improved here by even non-radical debulking. The vast majority of patients, however, ist not suitable to undergo hepatic resection. Palliative therapeutic options involve hepatic artery ligation or embolization, cryo-surgery and percutaneous laser coagulation, and various types of regional chemotherapy. These methods may enable a temporary relief of symptoms, but no significant impact on survival time, and no true long term benefit has been proven. Prospective randomized trials against combined treatment as well as untreated patients are required for a more meaningful judgement and improved effectiveness.
