From Biomarker Discovery to Targeted Clinical Application: Addressing Translational Gaps in Early Cancer Detection.

Area of Science:

• Oncology
• Biomarker Research
• Translational Science

Background:

• Breast cancer biomarker research has advanced significantly.
• However, few candidate biomarkers reach clinical validation for early detection.

Purpose of the Study:

• To examine the key translational barriers hindering biomarker progression.
• To identify gaps across the biomarker development continuum.

Main Methods:

• Review and analysis of translational challenges in biomarker development.
• Identification of five major translational gaps.

Main Results:

• Five key gaps identified: discovery-to-clinical relevance, methodological/analytical validation, regulatory complexity, real-world integration, and equity/deployment.
• These gaps highlight limitations in scientific rigor, validation, regulation, implementation, and healthcare equity.

Conclusions:

• Successful biomarker translation requires more than analytical validity.
• A supportive ecosystem is essential for effective breast cancer early detection and improved population outcomes.
