[Biomarkers in tumor pathology]

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Malignant transformation involves accumulating genetic alterations affecting key cellular pathways like senescence and apoptosis.
• Understanding cancer complexity relies on identifying functional impairments in biochemical pathways, as proposed by Hanahan and Weinberg.

Discussion:

• Molecular advances are crucial for biomarker discovery, including genetic alterations, proteins, and microRNAs.
• Biomarkers are essential for all phases of neoplastic disease, from risk assessment to treatment selection.

Key Insights:

• Over 30 inherited mutated genes increase tumor risk (e.g., colon, breast, thyroid).
• Biomarkers facilitate serological screening for early tumor detection and personalized treatment strategies.
• Newly discovered biomarkers can serve as therapeutic targets or indicate prognosis and treatment resistance.

Outlook:

• Personalized, molecularly-guided cancer treatments significantly improve survival rates for certain tumor types.
• Ongoing biomarker research offers hope for advancing oncology and improving patient outcomes.
