Colon cancer is one of the leading cancer diseases in the Western world, with most patients having localized tumors upon their initial diagnosis. Adjuvant chemotherapy is clearly recommended for patients with Dukes C disease. In Dukes B colon cancer, chemotherapy has only marginal effects and is therefore not routinely recommended. However, in patients with risk factors such as insufficient lymph node removal, perforation, etc., chemotherapy might have more impact and should be individually discussed with the patient. Routinely, the combination of oxaliplatin plus 5FU/LV (FOLFOX) should be used. Oral fluoropyrimidines may be given alternatively. Recent results questioned the benefit of adjuvant chemotherapy in elderly patients. Data on bevacizumab combined with FOLFOX did not meet the expectations and will be discussed in detail.
