Advanced Approaches to Breast Cancer Classification and Diagnosis.

Area of Science:

• Oncology
• Biomedical Engineering
• Molecular Diagnostics

Background:

• Global cancer deaths have significantly increased, with breast cancer (BC) being a major concern, affecting approximately one in eight women in the US.
• Current BC diagnostic methods like mammography and ultrasound often detect the disease at later stages, highlighting the need for early and advanced molecular diagnostic tools.
• BC is characterized by significant heterogeneity, with variations in growth patterns, cellular features, and biomarker expression, necessitating advanced diagnostic and therapeutic approaches.

Purpose of the Study:

• To review current breast cancer diagnosis and treatment options.
• To explore advanced biomarkers for developing state-of-the-art early screening and diagnostic technologies.
• To discuss the potential of non-invasive, point-of-care biosensors for rapid and accurate BC biomarker detection.

Main Methods:

• Review of current literature on breast cancer diagnosis and treatment.
• Analysis of histological and immuno-molecular studies on BC heterogeneity.
• Exploration of genetic advances and multigene assays for BC detection.
• Evaluation of FDA-approved biomarkers and their application in body fluid analysis.
• Discussion of portable biosensor technology for non-invasive biomarker detection.

Main Results:

• Traditional BC detection methods are often late-stage; early and advanced molecular diagnostics are in high demand.
• BC heterogeneity presents opportunities for developing advanced diagnostic and therapeutic tools by analyzing growth patterns and biomarkers.
• Portable biosensors offer a promising non-invasive, point-of-care solution for detecting BC biomarkers with high specificity and selectivity.
• Multigene assays and integration with clinicopathological information are crucial for predicting BC heterogeneity and recurrence, guiding personalized treatment.

Conclusions:

• There is a critical need for advanced, non-invasive diagnostic tools for early breast cancer detection.
• Harnessing BC heterogeneity and utilizing novel biomarkers with technologies like portable biosensors can revolutionize early screening and diagnosis.
• Personalized treatment strategies, informed by multigene assays and clinicopathological data, are essential for improving long-term patient outcomes.
