Mechanisms underlying invasion and metastasis

Area of Science:

• Oncology
• Cancer Biology
• Molecular Biology

Background:

• Despite advances in molecular characterization, therapies for advanced tumors and patient survival rates remain largely unchanged.
• Emerging evidence suggests tumor spread (metastasis) is regulated by mechanisms disrupting normal homeostatic processes.

Purpose of the Study:

• To review recent developments in understanding metastasis regulation.
• To highlight the role of the peritumoral stroma in cancer invasion and spread.

Main Methods:

• Literature review of recent studies on cancer metastasis.
• Analysis of evidence linking homeostatic disturbances to tumor spread.
• Focus on the role of the tumor microenvironment, specifically the peritumoral stroma.

Main Results:

• Consolidation of evidence that tumor spread involves disruptions in normal physiological processes.
• Identification of the peritumoral stroma as an active participant in modulating cancer invasion.

Conclusions:

• Understanding non-molecular regulatory mechanisms is crucial for advancing cancer therapy.
• The tumor microenvironment, particularly the stroma, represents a key target for future anti-metastasis strategies.
