Revolutionizing Artificial intelligence-assisted prostate cancer diagnosis with AI
Background: Prostate cancer diagnosis heavily relies on histopathological evaluation, which is subject to variability. While immunohistochemical staining (IHC) assists in distinguishing benign from malignant tissue, it increases workload, costs, and leads to diagnostic delays. Artificial intelligence (AI) presents a promising solution to reduce reliance on IHC by accurately classifying atypical glands and borderline morphologies in hematoxylin and eosin (H&E) stained tissue sections. Methods: In this study, we evaluated an AI model's ability to minimize IHC use without compromising diagnostic accuracy. We retrospectively analyzed prostate core needle biopsies from routine diagnostics at three different pathology sites. These cohorts consisted exclusively of diagnostically challenging cases where pathologists had required IHC to finalize the diagnosis.
Key Executive Insights
Results: We show that the AI model achieves high performance, with area under the curve values ranging from 0.951 to 0.993 for detecting cancer in routine H&E-stained slides. When applying sensitivity-prioritized diagnostic thresholds, the model reduces the need for IHC staining by 44.4%, 42.0%, and 20.7% across the three cohorts, without a single false negative prediction. Among slides with a benign ground truth label, IHC use is reduced by up to 80.6%.
Conclusions: This AI model shows promise for reducing unnecessary IHC use in difficult prostate biopsy cases while maintaining diagnostic safety. Its integration into clinical workflows could streamline decision-making in prostate pathology and alleviate resource burdens.

The AI model demonstrated high diagnostic accuracy across all cohorts. For the SUH internal validation cohort, the model achieved an AUC of 0.980. At a sensitivity-prioritized threshold of 0.01, it reduced IHC staining by 44.4% without any false negatives. In the SFR external validation cohort, the model reached an AUC of 0.993 and reduced IHC use by 42.0% (at threshold 0.01) with no false negatives. For the SCH external validation cohort, the AUC was 0.951, leading to a 20.7% IHC reduction (at threshold 0.01) without false negatives. This consistent performance indicates robust generalization across different institutions and scanner types.
The core strategy for reducing IHC involves leveraging the AI model's high confidence in benign morphology. When the AI predicts a very low probability of cancer (below a sensitivity-prioritized threshold like 0.01), it recommends against IHC, supporting a benign diagnosis. This approach allows pathologists to confidently forgo IHC in such cases, significantly reducing unnecessary staining. Conversely, if the AI indicates a higher cancer probability, it advises IHC, ensuring diagnostic safety. This systematic approach aims to standardize IHC ordering practices, minimizing variability and resource burden.
Integrating AI into clinical workflows requires careful planning for laboratory protocols, workflow dynamics, and user interactions. Prospective studies are essential to validate clinical and economic benefits, accounting for infrastructure, image processing times, and long-term operating expenses. The AI model's attention maps can also provide an additional layer of decision support, highlighting diagnostically challenging regions even when AI advises against IHC. This transformative opportunity can improve diagnostic precision, streamline workflows, and optimize resource utilization, contributing to better patient outcomes.

Case Study: AI-Driven IHC Reduction in Challenging Prostate Biopsies
Challenge: Pathologists frequently require basal-cell IHC to confirm diagnoses in cases with ambiguous H&E morphologies, leading to increased workload, costs, and delays. This is particularly prevalent in cases that ultimately prove to be benign but initially presented with low-level suspicion.
Solution: A task-specific AI model, trained on prostate cancer grading, was retrospectively applied to a cohort of challenging prostate biopsies where IHC had originally been performed. By implementing sensitivity-prioritized diagnostic thresholds, the AI identified cases that could confidently be signed out as benign without the need for IHC, while maintaining 100% sensitivity for cancer detection.
Impact: The AI model successfully reduced the need for IHC staining by an average of 35.7% across three independent cohorts (44.4%, 42.0%, and 20.7%) without a single false negative prediction. Notably, for slides with a benign ground truth, IHC use was reduced by up to 80.6%. This demonstrates AI's potential to significantly streamline diagnostic workflows, reduce resource burdens, and improve efficiency in prostate pathology while upholding diagnostic safety.
