Toward optimized front-line therapeutic strategies in patients with metastatic colorectal cancer--an expert review from the International Congress on Anti-Cancer Treatment (ICACT) 2009

Abstract

Metastatic colorectal cancer is a particularly frequent and severe cancer. Patients die mainly from metastatic disease; however, the survival of these patients has dramatically improved with the progress in chemotherapeutic regimens as new routes of administration and introduction of more potent cytotoxic agents administered in sequential 5-FU-folinic acid-irinotecan/5-FU-folinic acid-oxaliplatine strategies. Biologic therapies have been also developed targeting two different pathways, angiogenesis and the epidermal growth factor receptor. Their combination with chemotherapy leads to improved progression-free survival and overall survival in some cases as the addition of cetuximab in wild-type K-Ras tumors. The objectives of this expert conference were to review the different options, the available prognostic or predictive factors to optimally guide the treatment.
