Al-Driven Prediction of Cancer Pain Episodes: A Hybrid Decision Support Approach
This study proposes a hybrid machine learning (ML) and large language model (LLM) pipeline to predict cancer pain episodes in hospitalized lung cancer patients. By integrating structured EHR data with unstructured clinical notes, the model achieves high accuracy and sensitivity for 48-hour and 72-hour predictions, improving proactive pain management and resource allocation.

Machine Learning Module
The ML module integrates structured EHR data, including demographics, tumor stage, vital signs, and WHO-tiered analgesic use, to capture temporal medication trends. It employs various supervised learning models like Random Forest and XGBoost, augmented with SMOTE for imbalanced datasets, to predict pain episodes. This module provides statistical robustness and identifies key predictive features, adapting its focus from immediate clinical observations for 48-hour predictions to systemic inflammatory markers for 72-hour forecasts.
Large Language Model Module
The LLM module, powered by DeepSeek-R1, processes unstructured clinical notes to interpret ambiguous dosing records, rescue medication use, and free-text complaints. Utilizing a Retrieval-Augmented Generation (RAG) framework, it accesses a domain-specific knowledge base to enhance contextual reasoning and resolve inconsistencies. A carefully engineered prompt guides the LLM to provide clinically relevant, multi-faceted rationales, significantly improving interpretability and accuracy in complex or data-sparse scenarios.
Hybrid Integration & Performance
The hybrid ML+LLM framework combines the statistical robustness of ML with the contextual depth of LLMs. A decision-level fusion strategy ensures that the LLM augments ML predictions in cases of marginal confidence, enhancing both sensitivity and interpretability. This integrated approach significantly outperforms standalone models, reducing missed pain alerts and false positives, making it a reliable tool for real-time pain management in complex clinical scenarios.

Case Study: Hybrid Model Corrects ML Underestimation
In Case 2, the ML-only model significantly underestimated pain probability (0.24), failing to capture the patient's poor opioid response indicated in unstructured notes. The LLM module, however, correctly identified this critical factor and predicted high pain (0.95). The integrated ML+LLM framework leveraged both modalities to provide an accurate prediction of 'Yes', successfully addressing ML's limitation by incorporating contextual information, leading to better clinical decision support.
