Care of the cancer patient is becoming increasingly individualized. At the fulcrum of such therapeutic decision-making lies a relevant and accurate understanding of unique patient characteristics and preferences, and of tumor biology. In a pure sense, prognostic factors reflect tumor biology that may be used to estimate outcome independent of systemic treatment, whereas predictive factors reflect a relative resistance or sensitivity to specific therapy(ies) and are increasingly used to select optimal treatments for an individual patient. Perhaps the best and oldest example of a biomarker with proven clinical utility is the estrogen receptor alpha (ER), the expression of which on breast tumors has served both as a prognostic and predictive biomarker for the last three decades [1].
