Abstract:
Drug treatment of colorectal cancer has made impressive progress during the past 10 years. In addition to fluorouracil new anticancer drugs like irinotecan and oxaliplatin have become available. The activity of fluorouracil was optimized by using schedules of prolonged infusion. Capecitabine is an oral pro-drug of fluorouracil. When colorectal metastases are limited to the liver they should be resected if possible. Sometimes they can be reduced in size by primary chemotherapy (downstaging) and resected later. Very new and exciting are reports with the monoclonal antibody bevacizumab in combination with chemotherapy. Bevacizumab blocks angiogenesis. So far it is available only in the USA.
