In this review, we will discuss adjuvant chemotherapy in non-metastatic colon cancer, the existing prognostic and predictive molecular biomarkers in the field, and how to integrate these molecular biomarkers into the decision about whether to administer adjuvant therapy.

Use of Molecular Biomarkers to Inform Adjuvant Therapy for Colon Cancer

Monoclonal antibodies to the epidermal growth factor receptor (EGFR) are among the promising novel targeted therapies being explored in colorectal cancer. Two such agents that inhibit EGFR signaling by interfering with ligand-binding are cetuximab (Erbitux) and panitumumab (Vectibix). This review will address the use of cetuximab and panitumumab in chemotherapy-refractory colorectal cancer as well as in front-line therapy for the disease, consider predictors of response and resistance, and outline comparisons between these agents.

Monoclonal Antibodies to EGFR: What Does the Future Hold?

Damjanov and Meropol havedone an excellent job of reviewingboth the complex biologyof epidermal growth factor signalingand the current status ofepidermal growth factor receptor(EGFR, ErbB-1) inhibition for thetreatment of colorectal cancer. As theypoint out, several factors have madeEGFR a potentially high-value targetin cancer therapy. In addition, theyreview several phase II studies thathave demonstrated clinical activity foranti-EGFR antibodies in patients withadvanced colorectal cancer.
