Current and future approaches for the therapeutic targeting of metastasis (review)

Area of Science:

• Oncology
• Cancer Biology
• Molecular Medicine

Background:

• Metastasis is the primary cause of cancer mortality, accounting for approximately 90% of cancer deaths.
• Metastatic cancers often exhibit resistance to conventional chemotherapy, highlighting the need for innovative therapeutic strategies.
• Understanding the cellular and micro-environmental factors driving metastasis has led to the identification of novel molecular targets.

Purpose of the Study:

• To review promising molecular targets for anti-metastatic therapies.
• To provide examples of how these targets are being exploited in cancer treatment.
• To discuss the potential for synergistic effects when targeting multiple pathways.

Main Methods:

• Review of current scientific literature on metastasis mechanisms and therapeutic targets.
• Identification and categorization of key molecular targets, including intracellular enzymes, cell surface receptors, and extracellular matrix components.
• Analysis of preclinical and clinical strategies employing these targets.

Main Results:

• Several molecular targets, such as protein tyrosine kinases, cell surface receptors, and extracellular matrix factors, show promise for anti-metastatic therapies.
• Targeting these pathways can lead to multiple downstream antineoplastic effects.
• Synergistic therapeutic outcomes may be achieved by simultaneously targeting multiple factors.

Conclusions:

• Targeting specific molecular pathways involved in metastasis offers a promising avenue for developing novel anti-cancer treatments.
• Combination therapies that exploit these targets alongside conventional treatments may enhance efficacy against metastatic disease.
• Further research into these molecular targets is crucial for advancing the treatment of metastatic cancers.
