Study Notes
Biomarkers in Pathology
- Biomarkers are measurable molecules that signal biological or pathological processes, or treatment response.
Cancer Biomarkers
- Cancer biomarkers indicate cancer presence.
- These may originate from tumor cells, surrounding tissue, or bodily fluids.
- Examples include proteins like HER2 (breast/gastric cancer) and PSA.
Diagnostic Biomarkers
- Diagnostic biomarkers identify diseases like cancer.
- They encompass molecules, genes, or proteins measured for disease confirmation.
- Example: CD markers (like CD20 for B-cell lymphomas) identify lymphomas or leukemias.
Prognostic Biomarkers
- Prognostic biomarkers predict disease outcome (e.g., cancer).
- They assess disease severity, progression rate, and survival probability, irrespective of treatment.
- Example: A p53 mutation indicates poor prognosis in many cancers.
Predictive Biomarkers in Oncology
- Predictive biomarkers determine treatment response.
- These encompass genes, proteins, or other molecules.
- Example: EGFR mutations predict sensitivity to tyrosine kinase inhibitors in non-small cell lung cancer.
