In-Domain Supervised Pathology Report Classification: A Reproducible Pipeline from Data Curation to Production-Matched Evaluation
arXiv:2606.16026v1 Announce Type: new Abstract: We introduce an in-domain supervised pipeline designed to counter the out-of-distribution performance drop that hampers supervised biomedical NLP models, a problem observed when models trained on pathology reports are moved across cancer registries. Our contribution is a reproducible recipe for training a supervised classifier from routinely collected cancer registry data. It describes how to build the in-domain training set and a production-matched holdout, and to choose operating points that keep the false-negative rate (FNR) very low while kee
The proliferation of AI in healthcare, specifically in biomedical NLP, highlights the critical need for robust and reliable models that perform consistently across different data environments. This research addresses a known challenge in deploying such models directly.
This development provides a reproducible methodology for improving the generalization and integrity of AI models used in sensitive domains like pathology, ensuring more accurate diagnostic support and mitigating risks associated with out-of-distribution performance. It advances practical AI application in medical research and clinical settings.
The ability to develop more reliable, in-domain supervised classification pipelines means AI models can be deployed with higher confidence in diverse healthcare systems without significant performance degradation when transferred between cancer registries. It reduces a significant barrier to the broader adoption of AI in medical diagnostics.
