Response to first-line therapy is a primary determinant of outcome in patients with metastatic colorectal cancer (mCRC). In the past decade, the development of antiangiogenic and anti-EGFR biologic agents, doublet and triplet chemotherapy regimens, and combinations of these treatment modalities has created not only new first-line treatment options, but also new challenges for the management of this disease. In this Perspectives, these advances and the confusion surrounding their implications are discussed. The authors attempt to address some of the challenges in clinical decision-making and propose an algorithm for personalized allocation of first-line treatments in patients with mCRC.
