Targeting metastatic breast cancer: problems and potential

Area of Science:

• Oncology
• Cancer Biology
• Genomics

Background:

• Breast cancer is a leading cause of cancer mortality in women, primarily due to metastasis.
• Current therapies struggle against metastatic disease due to tumor dormancy, heterogeneity, and detection limitations.

Purpose of the Study:

• To highlight the critical need for understanding metastasis mechanisms distinct from primary tumors.
• To propose a comprehensive therapeutic strategy for progressive breast cancer.
• To advocate for a "Metastasis Genome Atlas" project.

Main Methods:

• Review of current understanding of breast cancer metastasis and therapy resistance.
• Conceptual framework for a multi-pronged therapeutic approach.
• Call for genomic research focused on metastasis.

Main Results:

• Identified challenges in current breast cancer adjuvant therapies against metastases.
• Proposed a three-pronged therapeutic strategy: blocking dissemination, eradicating disseminated cells, and eliminating established metastases.
• Emphasized the need for deeper knowledge of metastasis driver and maintenance genes.

Conclusions:

• A novel, multi-pronged therapeutic approach is essential for managing progressive breast cancer.
• Targeting metastasis-specific mechanisms and dormancy is crucial.
• A "Metastasis Genome Atlas" is needed to advance research and therapy development.
