An explainable machine learning approach for cervical cancer screening: decoding morphological diagnostic drivers
Background Cervical cancer screening in primary care is hindered by expert pathologist shortages and heavy diagnostic workloads, leading to fatigue-induced misdiagnoses. This study evaluated the diagnostic capacity, subpopulation robustness, and operational efficiency of an interpretable machine learning (ML) tool within a large Chinese healthcare network. Methods A retrospective database of 5,000 women was audited. Archived liquid-based cytology (LBC) digital slides were evaluated via a parallel validation chan…

Researchers audited 5,000 archived liquid-based cytology cases and compared an interpretable machine learning pipeline, LBC-NET, to a double-blind panel of senior cytopathologists for detection of high-grade squamous intraepithelial lesions or worse, testing robustness across age and clinical subgroups.
The reported gains in sensitivity and throughput suggest potential to alleviate pathologist shortages and fatigue-related errors in primary care screening, but the retrospective, single-network design leaves prospective performance, generalizability beyond the studied population, and long-term patient outcomes uncertain.
- Parallel validation compared LBC-NET pipeline against double-blind panel of senior cytopathologists on archived LBC digital slides.
- Diagnostic safety was stratified across age, vaginal infections, and menopause conditions with reported p > 0.05 for subpopulation differences.
- Transparency was quantified using game-theoretic Shapley Additive exPlanations (SHAP) and morphological feature tracking.
In a retrospective audit of 5,000 women, the LBC-NET pipeline detected HSIL+ with higher sensitivity than senior cytopathologists and reduced review time while increasing daily capacity.
The rundown
The study used a retrospective database of 5,000 women from a large Chinese healthcare network, evaluating archived liquid-based cytology digital slides through LBC-NET versus manual double-blind cytopathologist review.
Operational efficiency was assessed via continuous cumulative distribution curves, and SHAP analysis identified nucleus-to-cytoplasmic ratio and nuclear hyperchromasia intensity as core drivers of model predictions.
