Abstract
Metastases are generally an expression of widespread disease and therefore warrant systemic treatment. However, clinical observations have revealed that local surgical treatment might be beneficial in the case of organ-confined metastatic disease. Randomised studies have revealed that in the case of brain metastases, metastasectomy followed by radiotherapy, has a favourable outcome with respect to both the quality of life and overall survival. Retrospective non-randomised studies in selected patient groups show prolonged post-treatment survival in the case of both lung and liver metastasectomy. The most important prognostic factors for metastasectomy are: disease control elsewhere in the body, tumour species, the patient's general condition, and the possibility of a total resection of the metastasis. These factors form the basis of the separate decision-making process for each individual patient.
