DeepSeek for Pathology Report Understanding: A Benchmark Study of Cancer Type Extraction, AJCC Staging, and Prognosis Prediction
This benchmark study demonstrates that while DeepSeek models effectively extract cancer types and predict AJCC stages from 952 unstructured pathology reports, DeepSeek-extracted structured variables did not significantly improve prognosis prediction under the evaluated framework compared with using the original pathology report text directly, supporting a hybrid architecture that leverages DeepSeek for information extraction and staging while relying on traditional machine learning for outcome modeling.
