Machine Learning in Biomarker-Driven Precision Oncology: Automated Immunohistochemistry Scoring and Emerging Directions in Genitourinary Cancers
Manual IHC scoring is subjective, inconsistent, and lacks scalability, hindering precision oncology.
This review highlights how ML-driven digital pathology is automating immunohistochemistry (IHC) scoring, moving beyond manual interpretation. It details current applications in well-studied biomarkers like ER/PR and HER2, and explores emerging uses in genitourinary (GU) cancers (prostate, renal, bladder). The aim is to standardize biomarker quantification, accelerate discovery, and enhance precision oncology.
Executive Impact
ML-assisted IHC offers significant advancements in precision oncology by standardizing biomarker quantification, reducing inter-observer variability, and enabling high-throughput analysis. This translates into more accurate diagnoses, personalized treatment strategies, and accelerated biomarker discovery.

ML in HER2-Low Breast Cancer
ML models trained on curated HER2 datasets have achieved over 0.9 AUC for differentiating HER2-low status from negative, a critical distinction for eligibility for trastuzumab deruxtecan treatment. This highlights ML's technical feasibility in assessing weak membranous stains, a challenging task for human eyes.
Key Takeaway: ML enhances precision in HER2-low identification, improving patient selection for targeted therapies.
