Oxaliplatin and fluoropyrimidines are synergic combinations very active for the treatment of advanced colorectal cancer and for the adjuvant treatment of stage III colon cancer. Oxaliplatin-based regimens can be further strengthened by the addition of a third component, either a traditional drug such as irinotecan or targeted agents such as anti-vascular endothelial growth factor (VEGF) drugs, bevacizumab and aflibercept, or the anti-epidermal growth factor receptor (EGFR), cetuximab and panitumumab. The availabilty of all these active agents prompted several clinical trials on different lines of treatment of advanced colorectal cancer patients and in the adjuvant setting. Clinical studies involving the administration of anti-EGFR drugs also helped identify mutations in KRAS as a negative marker for the activity of these agents. However, positive selection criteria for targeted agents have not been identified. The results of oxaliplatin-containing regimens are critically presented and discussed in this review.
