Topology-Based Biomarkers Accurately Predict Breast Cancer Outcome and Survival

Area of Science:

• Computational biology
• Biomedical engineering
• Oncology

Background:

• Malignant transformation in breast cancer involves loss of tissue structure.
• Traditional histological assessments (e.g., grade) are subjective and have limited predictive value.
• Need for quantitative, objective biomarkers in breast cancer diagnosis and prognosis.

Purpose of the Study:

• To develop continuous mathematical scores reflecting tissue organization in breast cancer.
• To assess the prognostic accuracy of topology-based biomarkers compared to traditional methods.
• To integrate biomarkers with gene expression data for predicting therapeutic response.

Main Methods:

• Application of topological measurements and statistical modeling to human breast cancer tissues.
• Derivation of continuous mathematical scores from tissue architecture.
• Integration of topology-based biomarkers with gene expression data.

Main Results:

• Generated quantifiable, continuous biomarkers predicting breast cancer survival with higher accuracy.
• Topology-based measurements showed less variation across racial and ethnic groups.
• Developed topology-derived gene signatures predicting therapeutic response and uncovering regulatory networks.

Conclusions:

• Spatial and topological biomarkers show significant potential for breast cancer treatment and diagnosis.
• Quantitative analysis of tumor architecture offers a promising avenue for prognostic and predictive algorithms.
• Linking biology, medicine, and mathematics through quantitative biomarkers enhances understanding of breast cancer.
