Abstract
Colorectal cancer is a heterogeneous disease with a wide range of long-term outcomes and responses to treatment. Recent advances in the genetic and molecular characterization of tumors has yielded a set of prognostic and predictive biomarkers that aid the identification of patients at higher risk for disease recurrence and progression, and in some cases indicate the likelihood of response to a specific treatment. Increasingly, these biomarkers have become integral to the treatment algorithm for managing patients with colorectal cancer. Prognostic and predictive factors in colorectal cancer can broadly be categorized into treatment impact, clinicopathologic factors, and molecular markers. This review will focus primarily on molecular markers, which are foundational to the paradigmatic shift toward personalized cancer therapy.
