Molecular pathology of tumor metastasis. I. Predictive pathology

Area of Science:

• Oncology
• Molecular Biology
• Diagnostic Pathology

Background:

• Despite advances in primary tumor management, disseminated cancer remains a leading cause of death.
• Lack of understanding of molecular mechanisms driving tumor metastasis hinders clinical progress.
• Metastasis research is a key focus in oncology, generating fragmented but vital molecular data.

Purpose of the Study:

• To review current knowledge on the metastatic genotype and phenotype of major human solid tumors.
• To highlight the role of tumor cell-extracellular matrix interactions in tumor dissemination.
• To bridge basic research findings with diagnostic pathology for clinical application.

Main Methods:

• Literature review of metastasis research in oncology.
• Analysis of gene expression related to tumor cell-extracellular matrix interactions.
• Synthesis of data on metastatic potential in lung, colon, breast, prostate cancers, and melanoma.

Main Results:

• Tumor cell-extracellular matrix interactions are critical determinants of metastatic potential.
• Gene expression profiles can define the metastatic capabilities of malignant tumors.
• Fragmented molecular data on metastasis is increasingly available.

Conclusions:

• Translational diagnostic pathology can leverage basic research for clinical insights.
• Understanding metastatic mechanisms is essential for improving cancer treatment strategies.
• Further integration of molecular data into clinical practice is needed for managing metastatic disease.
