[Palliative treatment for colorectal cancer].

Over 50,000 new cases of colorectal cancer are diagnosed in Germany every year. About half of these patients will be cured by surgery. The other reoccur or present primarily with advanced disease. Recently, the survival of patients with metastasized disease has been prolonged from about 6 months with best supportive care alone to more than 20 months with combination chemotherapy. Therefore, adequate palliation is reasonable. Irresectable liver metastasis can be treated by locally ablative procedures such as radiofrequency ablation (RFA) or laserinduced thermotherapy (LITT). In the individual case resection of lung or brain metastasis should be discussed. Practitioners have to deal with plenty of supportive opportunities e.g. analgesics, bisphosphonates, central acting drugs, nutrition but also with drug side effects. In centers different endoscopic or interventional radiologic procedures are offered. Considering the variety of therapeutic options, it is prudent to discuss individual treatment plans in an interdisciplinary "tumor board" and involve the practitioners in the decision making.
