Area of Science:

• Oncology
• Molecular Pathology
• Genomics

Background:

• Metastatic disease evaluation increasingly utilizes molecular techniques.
• Traditional methods are complemented by advanced molecular analyses.

Purpose of the Study:

• To highlight the indispensable role of pathology in metastatic disease evaluation.
• To underscore the importance of integrated molecular analysis of tumors and their microenvironment.

Main Methods:

• In situ molecular techniques: immunohistochemistry, in situ hybridization, and fluorescence in situ hybridization (FISH).
• Molecular biology techniques applied to both frozen and fixed tissue samples.
• Analysis of tumor cells and their surrounding stroma, including immune cells.

Main Results:

• Integrated molecular approaches correlate genomic alterations with functional and structural changes.
• Tumor microenvironment analysis yields crucial prognostic and predictive biomarkers.
• Phenogenomic characterization of tumors as organs is achievable through comprehensive tissue analysis.

Conclusions:

• Pathology is mandatory for a complete understanding of metastatic disease.
• The integration of molecular techniques and microenvironment analysis is vital for advancing cancer diagnostics and therapeutics.
• Tissue analysis enables a shift from descriptive to functional genomics and integrated biology in oncology.
