Deciphering molecular pathways driving cancer invasion and metastasis: advances and therapeutic prospects

Area of Science:

• Oncology
• Molecular Biology
• Translational Medicine

Background:

• Metastasis is the leading cause of cancer mortality globally.
• Understanding the molecular circuits of metastatic progression is critical for developing effective treatments.

Purpose of the Study:

• To review recent advances in the molecular mechanisms of cancer metastasis.
• To examine therapeutic innovations targeting metastatic pathways.
• To discuss emerging technologies for metastasis detection and treatment.

Main Methods:

• Narrative review integrating expert-guided literature selection.
• Focus on molecular circuits: epithelial-mesenchymal transition (EMT), organotropism, extracellular matrix remodeling, angiogenesis, hypoxia-inducible signaling, migration modes, and tumor-immune interactions.
• Analysis of therapeutic strategies including EMT modulators, MMP inhibitors, VEGF/VEGFR inhibitors, hypoxia-activated prodrugs, and immunotherapies.

Main Results:

• Advances in understanding EMT, organotropism, and tumor-immune interactions.
• Development of targeted therapies like EMT modulators, VEGF/VEGFR inhibitors, and novel immunotherapies (ICB, CAR T-cells).
• Emerging technologies like nanotechnology, multi-omics, single-cell analysis, and CRISPR-Cas9 offer new tools for metastasis management.

Conclusions:

• Despite progress, challenges like intratumoral heterogeneity and resistance persist.
• Biomarker-guided, multi-target combinations and interdisciplinary collaboration are essential.
• Integrated strategies targeting tumor plasticity and microenvironment are key to transforming metastatic cancer outcomes.
