What is the Difference Between Prognostic and Predictive Biomarkers?
While prognostic biomarkers indicate the likely course of cancer irrespective of treatment, predictive biomarkers provide information about the likely response to a specific treatment. For example, EGFR mutations in non-small cell lung cancer serve as predictive biomarkers, suggesting that patients are likely to respond well to EGFR inhibitors. Understanding both types of biomarkers helps in personalizing cancer treatment.
